PART I

Items 1 and 2. Business and Properties.

General

     The parent company is the owner of Enterprise Products GP, which is the general partner of Enterprise Products Partners. The primary business purpose of Enterprise Products GP is to manage the affairs and operations of Enterprise Products Partners, which is a North American midstream energy company providing a wide range of services to producers and consumers of natural gas, natural gas liquids (“NGLs”), crude oil, and certain petrochemicals. Enterprise Products Partners is an industry leader in the development of pipeline and other midstream energy infrastructure in the continental United States and Gulf of Mexico. Enterprise Products Partners conducts substantially all of its business through a wholly owned subsidiary, Enterprise Products Operating L.P.

     We are a publicly traded Delaware limited partnership, the units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPE.” We were formed in April 2005 and completed our initial public offering of 14,216,784 units in August 2005. Our principal executive offices are located at 1100 Louisiana, 10^th Floor, Houston, Texas 77002 and our telephone number is (713) 381-6500.

     We are owned 99.99% by our limited partners and 0.01% by EPE Holdings. We, EPE Holdings, Enterprise Products GP and Enterprise Products Partners are affiliates and under common control of Dan L. Duncan, the Chairman and controlling shareholder of EPCO. We and Enterprise Products GP have no independent operations outside those of Enterprise Products Partners.

     We completed the “GulfTerra Merger” transactions in September 2004, whereby GulfTerra Energy Partners, L.P. (“GulfTerra”) merged with one of the wholly owned subsidiaries of Enterprise Products Partners. As a result of the GulfTerra Merger, GulfTerra and its consolidated subsidiaries and GulfTerra’s general partner (“GulfTerra GP”) became wholly owned subsidiaries of Enterprise Products Partners. The GulfTerra Merger expanded our asset base to include numerous natural gas and crude oil pipelines, offshore platforms and other midstream energy assets. In connection with the GulfTerra Merger, Enterprise Products Partners purchased various midstream energy assets from El Paso Corporation (“El Paso”) that are located in South Texas.

     In September 2006, Duncan Energy Partners, a Delaware limited partnership, was formed to acquire, own and operate a diversified portfolio of midstream energy assets from Enterprise Products Partners. Duncan Energy Partners completed its initial public offering of 14,950,000 common units in February 2007. The common units of Duncan Energy Partners are listed on the NYSE under the ticker symbol “DEP.” For additional information regarding Duncan Energy Partners, see “Recent Developments” within this Item 1.

Business Strategy

     Our primary objective is to increase cash available for distributions to our unitholders and, accordingly, the value of our limited partner interests. In recent years, major independent oil and gas and other energy companies have divested significant midstream assets. Additionally, there have been several transactions involving the sale of general partner interests in publicly traded partnerships. Asset rationalization among energy companies and transactions involving the sale of general partner interests is expected to continue. Our business strategy seeks to capitalize on these trends by:

§

managing Enterprise Products Partners for the successful execution of its business strategy;

	§		pursuing acquisitions of assets and businesses that may or may not be related to Enterprise Products Partners’ business in accordance with our business opportunity agreements; and
	§		acquiring general partner interests and associated incentive distribution rights and limited partner interests in other publicly traded partnerships.

Parent Company Assets

     The parent company’s cash generating assets consist entirely of its partnership interests in Enterprise Products Partners, from which it receives quarterly cash distributions. The parent company’s assets consist of the following partnership interests in Enterprise Products Partners:

	§		a 100% ownership interest in Enterprise Products GP, which owns a 2% general partner interest in Enterprise Products Partners that entitles Enterprise Products GP to receive 2% of the cash distributed by Enterprise Products Partners;
	§		the incentive distribution rights associated with Enterprise Products GP’s general partner interest in Enterprise Products Partners; and
	§		13,454,498 common units of Enterprise Products Partners, representing an approximate 3.1% limited partner interest in Enterprise Products Partners.

     As an incentive, Enterprise Products GP’s percentage interest in Enterprise Products Partners’ quarterly cash distributions is increased after certain specified target levels of distribution rates are met by Enterprise Products Partners. Enterprise Products GP’s quarterly incentive distribution thresholds are as follows:

	§		2% of quarterly cash distributions up to $0.253 per unit paid by Enterprise Products Partners;
	§		15% of quarterly cash distributions from $0.253 per unit up to $0.3085 per unit paid by Enterprise Products Partners; and
	§		25% of quarterly cash distributions that exceed $0.3085 per unit paid by Enterprise Products Partners.

Enterprise Products GP received incentive distributions from Enterprise Products Partners of $86.7 million, $63.9 million and $32.4 million in 2006, 2005 and 2004, respectively.

     The parent company has no separate operating activities apart from those conducted by Enterprise Products Partners. The parent company’s earnings primarily reflect equity in the income of its general and limited partner interests in Enterprise Products Partners. The following table summarizes key components of the parent company’s results of operations for the periods indicated (dollars in thousands):

		For the Year Ending December 31,
		2006				2005(1)
Equity in income of unconsolidated affiliates		$	111,093			$	24,507
Interest expense			9,547				3,445
Net income			99,499				20,631

     For additional information regarding the financial results of the parent company, see Note 1 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Financial Information by Business Segment

     For information regarding our business segments, see Note 16 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Recent Developments

     In September 2006, Duncan Energy Partners, a consolidated subsidiary of Enterprise Products Partners, was formed, to acquire, own, and operate a diversified portfolio of midstream energy assets. On February 5, 2007, this subsidiary completed its initial public offering of 14,950,000 common units (including an overallotment amount of 1,950,000 common units) at $21.00 per unit, which generated net proceeds to Duncan Energy Partners of $291.3 million. As consideration for assets contributed and reimbursement for capital expenditures related to these assets, Duncan Energy Partners distributed $260.6 million of these net proceeds to Enterprise Products Partners along with $198.9 million in borrowings under its credit facility and a final amount of 5,371,571 common units of Duncan Energy Partners. Duncan Energy Partners used $38.5 million of net proceeds from the overallotment to redeem 1,950,000 of the 7,301,571 common units it had originally issued to Enterprise Products Partners, resulting in the final amount of 5,371,571 common units beneficially owned by Enterprise Products Partners. Enterprise Products Partners used the cash it received from Duncan Energy Partners to temporarily reduce amounts outstanding under its Operating Partnership’s Multi-Year Revolving Credit Facility.

     In summary, Enterprise Products Partners contributed 66% of its equity interests in the following subsidiaries to Duncan Energy Partners:

	§		Mont Belvieu Caverns, LLC (“Mont Belvieu Caverns”), a recently formed subsidiary, which owns salt dome storage caverns located in Mont Belvieu, Texas that receive, store and deliver NGLs and certain petrochemical products for industrial customers located along the upper Texas Gulf Coast, which has the largest concentration of petrochemical plants and refineries in the United States;
	§		Acadian Gas, LLC (“Acadian Gas”), which owns an onshore natural gas pipeline system that gathers, transports, stores and markets natural gas in Louisiana. The Acadian Gas system links natural gas supplies from onshore and offshore Gulf of Mexico developments (including offshore pipelines, continental shelf and deepwater production) with local gas distribution companies, electric generation plants and industrial customers, including those in the Baton Rouge-New Orleans-Mississippi River corridor. A subsidiary of Acadian Gas owns a 49.5% equity interest in Evangeline Gas Pipeline, L.P. (“Evangeline”);
	§		Sabine Propylene Pipeline L.P. (“Sabine Propylene”), which transports polymer-grade propylene between Port Arthur, Texas and a pipeline interconnect located in Cameron Parish, Louisiana;
	§		Enterprise Lou-Tex Propylene Pipeline L.P. (“Lou-Tex Propylene”), which transports chemical-grade propylene from Sorrento, Louisiana to Mont Belvieu, Texas; and
	§		South Texas NGL Pipelines, LLC (“South Texas NGL”), a recently formed subsidiary, which began transporting NGLs from Corpus Christi, Texas to Mont Belvieu, Texas in January 2007. South Texas NGL owns the DEP South Texas NGL Pipeline System.

     In addition to the 34% ownership interest Enterprise Products Partners retained in each of these entities, it also owns the 2% general partner interest in Duncan Energy Partners and 26.4% of Duncan Energy Partners’ outstanding common units. The Operating Partnership of Enterprise Products Partners directs the business operations of Duncan Energy Partners through its control of the general partner of Duncan Energy Partners.

     The formation of Duncan Energy Partners had no effect on Enterprise Products Partners’ financial statements at December 31, 2006. For financial reporting purposes, the financial statements of Duncan Energy Partners will be consolidated into those of Enterprise Products Partners. Consequently, the results

of operations of Duncan Energy Partners will be a component of Enterprise Products Partners’ business segments. Also, due to common control of the entities by Dan L. Duncan, the initial consolidated balance sheet of Duncan Energy Partners will reflect the historical carrying basis of Enterprise Products Partners in each of the subsidiaries contributed to Duncan Energy Partners.

     The public owners of Duncan Energy Partners’ common units will be presented as a noncontrolling interest in Enterprise Products Partners consolidated financial statements beginning in February 2007. The public owners of Duncan Energy Partners have no direct equity interests in the common units of Enterprise Products Partners as a result of this transaction. The borrowings of Duncan Energy Partners will be presented as part of Enterprise Products Partners’ consolidated debt; however, neither the parent company nor Enterprise Products Partners has any obligation for the payment of interest or repayment of borrowings incurred by Duncan Energy Partners.

     Enterprise Products Partners has significant involvement with all of the subsidiaries of Duncan Energy Partners, including the following types of transactions:

	§		It utilizes storage services provided by Mont Belvieu Caverns to support its Mont Belvieu fractionation and other businesses;
	§		It buys natural gas from and sells natural gas to Acadian Gas in connection with its normal business activities; and
	§		It is the sole shipper on the DEP South Texas NGL Pipeline System.

     Enterprise Products Partners may contribute other equity interests in its subsidiaries to Duncan Energy Partners in the near term and use the proceeds it receives from Duncan Energy Partners to fund its capital spending program. Enterprise Products Partners has no obligation or commitment to make such contributions to Duncan Energy Partners.

     For information regarding our other recent developments, see “Overview of Business — Recent Developments” included under Item 7 of this annual report, which is incorporated by reference into this Item 1.

     For recent developments involving releases of ammonia from a third-party pipeline operated by the Operating Partnership through an indirect wholly owned subsidiary, see Item 3 of this annual report.

Segment Discussion

     Our midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States, Canada and the Gulf of Mexico with domestic consumers and international markets. We have four reportable business segments:

	§		NGL Pipelines & Services;
	§		Onshore Natural Gas Pipelines & Services;
	§		Offshore Pipelines & Services; and
	§		Petrochemical Services.

     Our business segments are generally organized and managed according to the type of services rendered (or technologies employed) and products produced and/or sold.

     The following sections present an overview of our business segments, including information regarding the principal products produced, services rendered, seasonality, competition and regulation. Our results of operations and financial condition are subject to a variety of risks. For information regarding our key risk factors, see Item 1A of this annual report.

     NGL Pipelines & Services

     Our NGL Pipelines & Services business segment includes our (i) natural gas processing business and related NGL marketing activities, (ii) NGL pipelines aggregating approximately 13,295 miles and related storage facilities including our Mid-America Pipeline System and (iii) NGL fractionation facilities located in Texas and Louisiana. This segment also includes our import and export terminal operations.

     NGL products (ethane, propane, normal butane, isobutane and natural gasoline) are used as raw materials by the petrochemical industry, feedstocks by refiners in the production of motor gasoline and by industrial and residential users as fuel. Ethane is primarily used in the petrochemical industry as a feedstock for ethylene production, one of the basic building blocks for a wide range of plastics and other chemical products. Propane is used both as a petrochemical feedstock in the production of ethylene and propylene and as a heating, engine and industrial fuel. Normal butane is used as a petrochemical feedstock in the production of ethylene and butadiene (a key ingredient of synthetic rubber), as a blendstock for motor gasoline and to derive isobutane through isomerization. Isobutane is fractionated from mixed butane (a mixed stream of normal butane and isobutane) or produced from normal butane through the process of isomerization, principally for use in refinery alkylation to enhance the octane content of motor gasoline, in the production of isooctane and other octane additives, and in the production of propylene oxide. Natural gasoline, a mixture of pentanes and heavier hydrocarbons, is primarily used as a blendstock for motor gasoline or as a petrochemical feedstock.

     Natural gas processing and related NGL marketing activities. At the core of our natural gas processing business are 23 processing plants located in Texas, Louisiana, Mississippi, New Mexico and Wyoming. Natural gas produced at the wellhead and in association with crude oil contains varying amounts of NGLs. This “rich” natural gas in its raw form is usually not acceptable for transportation in the nation’s major natural gas pipeline systems or for commercial use as a fuel. Natural gas processing plants remove the NGLs from the natural gas stream, enabling the natural gas to meet transmission pipeline and commercial quality specifications. In addition, on an energy equivalent basis, NGLs generally have a greater economic value as a raw material for petrochemical and motor gasoline production than their value

as components of the natural gas stream. After extraction, we typically transport the mixed NGLs to a centralized facility for fractionation (or separation) into purity NGL products such as ethane, propane, normal butane, isobutane and natural gasoline. The purity NGL products can then be used in our NGL marketing activities to meet contractual requirements or sold on spot and forward markets.

     When operating and extraction costs of natural gas processing plants are higher than the incremental value of the NGL products that would be extracted from a stream of natural gas, the recovery levels of certain NGL products, principally ethane, may be reduced or eliminated. This leads to a reduction in NGL volumes available for transportation and fractionation.

     In our natural gas processing activities, we enter into margin-band contracts, percent-of-liquids contracts, percent-of-proceeds contracts, fee-based contracts, hybrid contracts (mixed percent-of-liquids and fee-based) and keepwhole contracts. Under margin-band and keepwhole contracts, we take ownership of mixed NGLs extracted from the producer’s natural gas stream and recognize revenue when the extracted NGLs are delivered and sold to customers on NGL marketing sales contracts. In the same way, revenue is recognized under our percent-of-liquids contracts except that the volume of NGLs we extract and sell is less than the total amount of NGLs extracted from the producers’ natural gas. Under a percent-of-liquids contract, the producer retains title to the remaining percentage of mixed NGLs we extract. Under a percent-of-proceeds contract, we share in the proceeds generated from the sale of the mixed NGLs we extract on the producer’s behalf. If a cash fee for natural gas processing services is stipulated by the contract, we record revenue when the natural gas has been processed and delivered to the producer. The NGL volumes we earn and take title to in connection with our processing activities are referred to as our equity NGL production.

     In general, our percent-of-liquids, hybrid and keepwhole contracts give us the right (but not the obligation) to process natural gas for a producer; thus, we are protected from processing at an economic loss during times when the sum of our costs exceeds the value of the mixed NGLs of which we would take ownership. Generally, our natural gas processing agreements have terms ranging from month-to-month to life of the producing lease. Intermediate terms of one to ten years are also common.

     To the extent that we are obligated under our margin-band and keepwhole gas processing contracts to compensate the producer for the energy value of mixed NGLs we extract from the natural gas stream, we are exposed to various risks, primarily commodity price fluctuations. However, our margin band contracts contain terms which limit our exposure to such risks. The prices of natural gas and NGLs are subject to fluctuations in response to changes in supply, market uncertainty and a variety of additional factors that are beyond our control. Periodically, we attempt to mitigate these risks through the use of commodity financial instruments.

     Our NGL marketing activities generate revenues from the sale and delivery of NGLs obtained through our processing activities and purchases from third parties on the open market. These sales contracts may also include forward product sales contracts. In general, the sales prices referenced in these contracts are market-related and can include pricing differentials for such factors as delivery location.

     NGL pipelines, storage facilities and import/export terminals. Our NGL pipeline, storage and terminalling operations include approximately 13,295 miles of NGL pipelines, 162 million barrels of underground NGL and related product storage working capacity and two import/export facilities.

     Our NGL pipelines transport mixed NGLs and other hydrocarbons to fractionation plants; distribute and collect NGL products to and from petrochemical plants and refineries; and deliver propane to customers along the Dixie Pipeline and certain sections of the Mid-America Pipeline System. Revenue from our NGL pipeline transportation agreements is generally based upon a fixed fee per gallon of liquids transported multiplied by the volume delivered. Accordingly, the results of operations for this business are generally dependent upon the volume of product transported and the level of fees charged to customers (including those charged to our NGL and petrochemical marketing activities, which are eliminated in consolidation). The transportation fees charged under these arrangements are either contractual or regulated by governmental agencies, including the Federal Energy Regulatory Commission (“FERC”).

Typically, we do not take title to the products transported in our NGL pipelines; rather, the shipper retains title and the associated commodity price risk.

     Our NGL and related product storage facilities are integral parts of our operations. In general, our underground storage wells are used to store our and our customers’ mixed NGLs, NGL products and petrochemical products. Under our NGL and related product storage agreements, we charge customers monthly storage reservation fees to reserve a specific storage capacity in our underground caverns. The customers pay reservation fees based on the quantity of capacity reserved rather than on the amount of reserved capacity utilized. When a customer exceeds its reserved capacity, we charge those customers an excess storage fee. In addition, we charge our customers throughput fees based on volumes injected and withdrawn from the storage facility. Accordingly, the profitability of our storage operations is dependent upon the level of capacity reserved by our customers, the volume of product injected and withdrawn from our underground caverns and the level of fees charged.

     We operate NGL import and export facilities located on the Houston Ship Channel in southeast Texas. Our import facility is primarily used to offload volumes for delivery to our NGL storage and processing facilities near Mont Belvieu, Texas. Our export facility includes an NGL products chiller and related equipment used for loading refrigerated marine tankers for third-party export customers. Revenues from our import and export services are primarily based on fees per unit of volume loaded or unloaded and may also include demand payments. Accordingly, the profitability of our import and export activities primarily depends upon the available quantities of NGLs to be loaded and offloaded and the fees we charge for these services.

     NGL fractionation. We own or have interests in seven NGL fractionation facilities located in Texas and Louisiana. NGL fractionation facilities separate mixed NGL streams into purity NGL products. The three primary sources of mixed NGLs fractionated in the United States are (i) domestic natural gas processing plants, (ii) domestic crude oil refineries and (iii) imports of butane and propane mixtures. The mixed NGLs delivered from domestic natural gas processing plants and crude oil refineries to our NGL fractionation facilities are typically transported by NGL pipelines and, to a lesser extent, by railcar and truck.

     Extraction of mixed NGLs by natural gas processing plants represent the largest source of volumes processed by our NGL fractionators. Based upon industry data, we believe that sufficient volumes of mixed NGLs, especially those originating from Gulf Coast and Rocky Mountain natural gas processing plants, will be available for fractionation in commercially viable quantities for the foreseeable future. Significant volumes of mixed NGLs are contractually committed to our NGL fractionation facilities by joint owners and third-party customers.

     The majority of our NGL fractionation facilities process mixed NGL streams for third-party customers and support our NGL marketing activities under fee-based arrangements. These fees (typically in cents per gallon) are subject to adjustment for changes in certain fractionation expenses, including natural gas fuel costs. At our Norco facility, we perform fractionation services for certain customers under percent-of-liquids contracts. The results of operations of our NGL fractionation business are dependent upon the volume of mixed NGLs fractionated and either the level of fractionation fees charged (under fee-based contracts) or the value of NGLs received (under percent-of-liquids arrangements). We are exposed to fluctuations in NGL prices to the extent we fractionate volumes for customers under percent-of-liquids arrangements. Our fee-based customers generally retain title to the NGLs that we process for them.

     Seasonality. Our natural gas processing and NGL fractionation operations exhibit little to no seasonal variation. Likewise, our NGL pipeline operations have not exhibited a significant degree of seasonality overall. However, propane transportation volumes are generally higher in the October through March timeframe in connection with increased use of propane for heating in the upper Midwest and southeastern United States. Our facilities located in the southern United States may be affected by weather events such as hurricanes and tropical storms in the Gulf of Mexico.

     We operate our NGL and related product storage facilities based on the needs and requirements of our customers in the NGL, petrochemical, heating and other related industries. We usually experience an increase in the demand for storage services during the spring and summer months due to increased feedstock storage requirements for motor gasoline production and a decrease during the fall and winter months when propane inventories are being drawn for heating needs. In general, our import volumes peak during the spring and summer months and our export volumes are at their highest levels during the winter months.

     In support of our commercial goals, our NGL marketing activities rely on inventories of mixed NGLs and purity NGL products. These inventories are the result of accumulated equity NGL production volumes, imports and other spot and contract purchases. Our inventories of ethane, propane and normal butane are typically higher in summer months as each are normally in higher demand and at higher price levels during winter months. Isobutane and natural gasoline inventories are generally stable throughout the year. Our inventory cycle begins in late-February to mid-March (the seasonal low point); builds through September; remains level until early December; before being drawn through winter until the seasonal low is reached again.

     Competition. Our natural gas processing business and NGL marketing activities encounter competition from fully integrated oil companies, intrastate pipeline companies, major interstate pipeline companies and their non-regulated affiliates, and independent processors. Each of our competitors has varying levels of financial and personnel resources, and competition generally revolves around price, service and location.

     In the markets served by our NGL pipelines, we compete with a number of intrastate and interstate liquids pipelines companies (including those affiliated with major oil, petrochemical and gas companies) and barge, rail and truck fleet operations. In general, our NGL pipelines compete with these entities in terms of transportation fees and service.

     Our competitors in the NGL and related product storage businesses are integrated major oil companies, chemical companies and other storage and pipeline companies. We compete with other storage service providers primarily in terms of the fees charged, number of pipeline connections and operational dependability. Our import and export operations compete with those operated by major oil and chemical companies primarily in terms of loading and offloading volumes per hour.

     We compete with a number of NGL fractionators in Texas, Louisiana and Kansas. Although competition for NGL fractionation services is primarily based on the fractionation fee charged, the ability of an NGL fractionator to receive mixed NGLs, store and distribute NGL products is also an important competitive factor and is a function of the existence of the necessary pipeline and storage infrastructure.

     Properties. The following table summarizes the significant NGL pipelines and related storage assets of our NGL Pipelines & Services business segment at February 5, 2007.

     The maximum number of barrels that our NGL pipelines can transport per day depends upon the operating balance achieved at a given point in time between various segments of the systems. Since the operating balance is dependent upon the mix of products to be shipped and demand levels at various delivery points, the exact capacities of our NGL pipelines cannot be determined. We measure the utilization rates of such pipelines in terms of net throughput (i.e., on a net basis in accordance with our ownership interest). Total net throughput volumes for these pipelines were 1,450 MBPD, 1,360 MBPD and 1,343 MBPD during the years ended December 31, 2006, 2005 and 2004, respectively.

     The following information highlights the general use of each of our principal NGL pipelines. We operate our NGL pipelines with the exception of Tri-States and a small portion of the Louisiana Pipeline System.

§

The Mid-America Pipeline System is a regulated NGL pipeline system consisting of three primary segments: the 2,568-mile Rocky Mountain pipeline, the 2,771-mile Conway North pipeline and the 2,039-mile Conway South pipeline. This system covers thirteen states: Wyoming, Utah, Colorado, New Mexico, Texas, Oklahoma, Kansas, Missouri, Nebraska, Iowa, Illinois, Minnesota and Wisconsin. The Rocky Mountain pipeline transports mixed NGLs from the Rocky Mountain Overthrust and San Juan Basin areas to the Hobbs hub located on the Texas-New Mexico border. The Conway North segment links the NGL hub at Conway, Kansas to refineries, petrochemical plants and propane markets in the upper Midwest. In addition, the Conway North segment has access to NGL supplies from Canada’s Western Sedimentary Basin through third-party connections. The Conway South pipeline connects the Conway hub with Kansas refineries and

			transports NGLs from Conway, Kansas to the Hobbs hub. The Mid-America Pipeline System interconnects with our Seminole Pipeline at the Hobbs hub. We also own fifteen unregulated propane terminals that are an integral part of the Mid-America Pipeline System.
			During 2006, approximately 54% of the volumes transported on the Mid-America Pipeline System were mixed NGLs originating from natural gas processing plants located in the Permian Basin in west Texas, the Hugoton Basin of southwestern Kansas, the San Juan Basin of northwest New Mexico, and the Greater Green River Basin of southwestern Wyoming. The remaining volumes are generally purity NGL products originating from NGL fractionators in the mid-continent areas of Kansas, Oklahoma, and Texas, as well as deliveries from Canada.
	§		The Dixie Pipeline is a regulated propane pipeline extending from southeast Texas and Louisiana to markets in the southeastern United States. Propane supplies transported on this system primarily originate from southeast Texas, southern Louisiana and Mississippi. This system operates in seven states: Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina and North Carolina.
	§		The Seminole Pipeline is a regulated pipeline that transports NGLs from the Hobbs hub and the Permian Basin area of west Texas to markets in southeastern Texas. NGLs originating on the Mid-America Pipeline System are the primary source of throughput for the Seminole Pipeline.
	§		The EPD South Texas NGL System is a network of NGL gathering and transportation pipelines located in south Texas. The system includes 379 miles of pipeline used to gather and transport mixed NGLs from our south Texas natural gas processing facilities to our south Texas NGL fractionation facilities. The pipeline system also includes approximately 660 miles of pipelines that deliver NGLs from our south Texas fractionation facilities to refineries and petrochemical plants located between Corpus Christi and Houston, Texas and within the Texas City-Houston area, as well as to common carrier NGL pipelines.
	§		The Louisiana Pipeline System is a network of NGL pipelines located in Louisiana. This system transports NGLs originating in southern Louisiana and Texas to refineries and petrochemical companies along the Mississippi River corridor in southern Louisiana. This system also provides transportation services for our natural gas processing plants, NGL fractionators and other facilities located in Louisiana.
	§		The Promix NGL Gathering System is a NGL pipeline system that gathers mixed NGLs from natural gas processing plants in Louisiana for delivery to an NGL fractionator owned by K/D/S Promix, L.L.C. (“Promix”). This gathering system is an integral part of the Promix NGL fractionation facility. Our ownership interest in this pipeline is held indirectly through our equity method investment in Promix.
	§		The DEP South Texas NGL Pipeline System transports NGLs from our Shoup and Armstrong fractionation facilities in south Texas to Mont Belvieu, Texas. This system became operational in January 2007. We purchased 220 miles of this pipeline from ExxonMobil Pipeline Company in August 2006. In addition, we lease an 11-mile segment of this pipeline system from TEPPCO. The remaining 55 miles of this pipeline were either acquired from TEPPCO (10 miles) or constructed by us (45 miles).
			Enterprise Products Partners contributed a direct 66% equity interest in South Texas NGL, its subsidiary that owns the DEP South Texas NGL Pipeline System, to Duncan Energy Partners on February 5, 2007. Enterprise Products Partners owns the remaining 34% direct interest in South Texas NGL. For additional information regarding this subsequent event, see “Recent Developments” within this Item 1.
	§		The Houston Ship Channel pipeline system is a collection of pipelines extending from our Houston Ship Channel import/export facility and Morgan’s Point facility to Mont Belvieu, Texas. This system is used to deliver NGL products to third-party petrochemical plants and refineries as well as to deliver feedstocks to our Mont Belvieu facilities.

§

The Lou-Tex NGL pipeline system is used to provide transportation services for NGLs and refinery grade propylene between the Louisiana and Texas markets. We also use this pipeline to transport mixed NGLs from certain of our Louisiana gas processing plants to our Mont Belvieu NGL fractionation facility.

     In addition to the pipelines identified above, we have begun construction on the Meeker pipeline in the Piceance Basin area of western Colorado. This new 50-mile pipeline will transport mixed NGLs from our Meeker natural gas processing facility to the Mid-America Pipeline System.

     Our NGL and related product storage facilities are integral parts of our pipeline and other operations. In general, these underground storage facilities are used to store NGLs and petrochemical products for us and our customers. Our underground storage facilities include locations in Arizona, Kansas and Utah that were acquired in July 2005. We operate these facilities, with the exception of certain storage locations operated for us by a third party in Louisiana and Mississippi.

     Enterprise Products Partners contributed a direct 66% equity interest in its recently formed subsidiary, Mont Belvieu Caverns, to Duncan Energy Partners on February 5, 2007. Enterprise Products Partners owns the remaining 34% direct interest in Mont Belvieu Caverns.

     Mont Belvieu Caverns owns 33 underground storage caverns with an aggregate underground storage capacity of approximately 100 MMBbls, and a brine system with approximately 20 MMBbls of above-ground storage pit capacity and two brine production wells. These assets store and deliver NGLs (such as ethane and propane) and certain petrochemical products for industrial customers located along the upper Texas Gulf Coast.

     At the core of our natural gas processing business are 23 processing plants located in Texas, Louisiana, Mississippi, New Mexico and Wyoming. Our natural gas processing facilities can be characterized as two distinct types: (i) straddle plants situated on mainline natural gas pipelines owned either by us or by third parties or (ii) field plants that process natural gas from gathering pipelines. We operate the Toca, Chaco, North Terrebonne, Calumet, Neptune, Carlsbad and Pioneer plants and all of the Texas facilities. In addition to the natural gas processing plants noted above, we have begun construction on the Meeker facility and a new natural gas processing facility adjacent to our existing Pioneer plant. The Meeker facility will be constructed in the Piceance Basin of western Colorado and will have the capacity to process 1.7 Bcf/d of natural gas. Our new Pioneer natural gas processing plant located in Opal, Wyoming will have a natural gas processing capacity of 0.75 Bcf/d. On a weighted-average basis, utilization rates for these assets were 56%, 53% and 61% during the years ended December 31, 2006, 2005 and 2004, respectively. These rates reflect the periods in which we owned an interest in such facilities.

     Our NGL marketing activities utilize a fleet of approximately 830 railcars, the majority of which are leased. These railcars are used to deliver feedstocks to our facilities and to distribute NGLs throughout the United States and parts of Canada. We have rail loading and unloading facilities in Alabama, Arizona,

California, Kansas, Louisiana, Minnesota, Mississippi, Nevada, North Carolina and Texas. These facilities service both our rail shipments and those of our customers.

     The following information highlights the general use of each of our principal NGL fractionation facilities. We operate all of our NGL fractionation facilities.

	§		Our Mont Belvieu NGL fractionation facility is located at Mont Belvieu, Texas, which is a key hub of the domestic and international NGL industry. This facility fractionates mixed NGLs from several major NGL supply basins in North America including the Mid-Continent, Permian Basin, San Juan Basin, Rocky Mountain Overthrust, East Texas and the Gulf Coast.
	§		The Norco NGL fractionation facility receives mixed NGLs via pipeline from refineries and natural gas processing plants located in southern Louisiana and along the Mississippi and Alabama Gulf Coast, including our Yscloskey, Pascagoula and Toca facilities.
	§		The Promix NGL fractionation facility receives mixed NGLs via pipeline from natural gas processing plants located in southern Louisiana and along on the Mississippi Gulf Coast, including our Calumet, Neptune, Burns Point and Pascagoula facilities. In addition to the 362-mile Promix NGL Gathering System, Promix owns five NGL storage caverns and a barge loading facility that is integral to its operations.
	§		Our Shoup and Armstrong NGL fractionation facilities fractionate mixed NGLs supplied by our south Texas natural gas processing plants. The Shoup and Armstrong facilities supply NGLs transported by the DEP South Texas NGL Pipeline System.
	§		The BRF facility processes mixed NGLs from natural gas processing plants located in Alabama, Mississippi and southern Louisiana.

     On a weighted-average basis, utilization rates for our NGL fractionators were 75%, 74% and 70% during the years ended December 31, 2006, 2005 and 2004, respectively. These rates reflect the periods in which we owned an interest in such facilities. We own direct consolidated interests in all of our NGL fractionation facilities with the exception of a 50% interest in a facility owned by Promix and a 32.2% interest in a facility owned by Baton Rouge Fractionators LLC (“BRF”).

     Our NGL operations include import and export facilities located on the Houston Ship Channel in southeast Texas. We lease an import facility that can offload NGLs from tanker vessels at a rate of 10,000 barrels per hour. In addition, we own an export facility that currently loads cargoes of refrigerated propane and butane onto tanker vessels at rates of up to 5,000 barrels per hour. We are in the process of expanding our import and export facility. In addition, we own a barge dock that can load or offload two barges of NGLs or refinery-grade propylene simultaneously at rates up to 5,000 barrels per hour. Our average combined NGL import and export volumes were 127 MBPD, 119 MBPD and 91 MBPD for 2006, 2005 and 2004, respectively.

     Onshore Natural Gas Pipelines & Services

     Our Onshore Natural Gas Pipelines & Services business segment includes approximately 18,889 miles of onshore natural gas pipeline systems that provide for the gathering and transmission of natural gas in Alabama, Colorado, Louisiana, Mississippi, New Mexico, Texas and Wyoming. In addition, we own two salt dome natural gas storage facilities located in Mississippi and lease natural gas storage facilities located in Texas and Louisiana.

     Onshore natural gas pipelines. Our onshore natural gas pipeline systems provide for the gathering and transmission of natural gas from onshore developments, such as the San Juan, Barnett Shale, Permian, Piceance and Greater Green River supply basins in the Western U.S., or from offshore developments in the Gulf of Mexico through connections with offshore pipelines. Typically, these systems receive natural gas from producers, other pipelines or shippers through system interconnects and redeliver the natural gas to

processing facilities, local gas distribution companies, industrial or municipal customers or to other onshore pipelines.

     Certain of our onshore natural gas pipelines generate revenues from transportation agreements where shippers are billed a fee per unit of volume transported (typically in MMBtus) multiplied by the volume delivered. The transportation fees charged under these arrangements are either contractual or regulated by governmental agencies, including the FERC. Intrastate natural gas pipelines (such as our Acadian Gas and Alabama Intrastate systems) may also purchase natural gas from producers and suppliers and resell such natural gas to customers such as electric utility companies, local natural gas distribution companies and industrial customers.

     Our Texas, Acadian Gas and Alabama Intrastate pipelines are exposed to commodity price risk to the extent they take title to natural gas volumes through certain of their contracts. In addition, our San Juan Gathering, Permian Basin and Jonah pipeline systems provide aggregating and bundling services, in which we purchase and resell natural gas for certain small producers. Also, several of our gathering systems, while not providing marketing services, have some exposure to risks related to commodity prices through transportation arrangements with shippers. For example, approximately 94% of the fee-based gathering arrangements of our San Juan Gathering System are calculated using a percentage of a regional price index for natural gas. We use commodity financial instruments from time to time to mitigate our exposure to risks related to commodity prices.

     Underground natural gas storage. We own two underground salt dome natural gas storage facilities located near Hattiesburg, Mississippi that are ideally situated to serve the domestic Northeast, Mid-Atlantic and Southeast natural gas markets. On a combined basis, these facilities (our Petal Gas Storage (“Petal”) and Hattiesburg Gas Storage (“Hattiesburg”) locations) are capable of delivering in excess of 1.4 Bcf/d of natural gas into five interstate pipeline systems. We also lease underground salt dome natural gas storage caverns that serve markets in Texas and Louisiana.

     The ability of salt dome storage caverns to handle high levels of injections and withdrawals of natural gas benefits customers who desire the ability to meet load swings and to cover major supply interruption events, such as hurricanes and temporary losses of production. High injection and withdrawal rates also allow customers to take advantage of periods of volatile natural gas prices and respond in situations where they have natural gas imbalance issues on pipelines connected to the storage facilities. Our salt dome storage facilities permit sustained periods of high natural gas deliveries, including the ability to quickly switch from full injection to full withdrawal.

     Under our natural gas storage contracts, there are typically two components of revenues: (i) monthly demand payments, which are associated with storage capacity reservations and paid regardless of the customer’s usage, and (ii) storage fees per unit of volume stored at our facilities.

     Seasonality. Typically, our onshore natural gas pipelines experience higher throughput rates during the summer months as gas-fired power generation facilities increase output for residential and commercial demand for electricity for air conditioning. Likewise, seasonality impacts the timing of injections and withdrawals at our natural gas storage facilities. In the winter months, natural gas is needed as fuel for residential and commercial heating, and during the summer months, natural gas is needed by power generation facilities due to the demand for electricity for air conditioning.

     Competition. Within their market areas, our onshore natural gas pipelines compete with other onshore natural gas pipelines on the basis of price (in terms of transportation fees and/or natural gas selling prices), service and flexibility. Our competitive position within the onshore market is enhanced by our longstanding relationships with customers and the limited number of delivery pipelines connected (or capable of being economically connected) to the customers we serve.

     Competition for natural gas storage is primarily based on location and the ability to deliver natural gas in a timely and reliable manner. Our natural gas storage facilities compete with other providers of natural gas storage, including other salt dome storage facilities and depleted reservoir facilities. We believe

that the locations of our natural gas storage facilities allow us to compete effectively with other companies who provide natural gas storage services.

     The following information highlights the general use of each of our principal onshore natural gas pipelines and storage facilities, all of which we operate.

§

The Texas Intrastate System gathers and transports natural gas from supply basins in Texas (from both onshore and offshore sources) to local gas distribution companies and electric generation and industrial and municipal consumers. This system serves important natural gas producing regions and commercial markets in Texas, including Corpus Christi, the San Antonio/Austin area, the Beaumont/Orange area, the Houston area, and the Houston Ship Channel industrial market. The Texas Intrastate System is comprised of the 7,292-mile Enterprise Texas Intrastate pipeline system, the 197-mile TPC Offshore gathering system and the 651-mile Channel pipeline system. The leased Wilson natural gas storage facility is an integral part of the Texas Intrastate System. We own 100% of the Texas Intrastate System with the exception of the Channel pipeline system, in which we own a 50% undivided interest.

	§		The Jonah Gathering System is located in the Greater Green River Basin of southwestern Wyoming. This system gathers natural gas from the Jonah and Pinedale fields for delivery to regional natural gas processing plants, including our Pioneer facility, and major interstate pipelines. In August 2006, we entered into a joint venture with TEPPCO and are proceeding with an expansion of the Jonah Gathering System. For additional information regarding this joint venture arrangement with TEPPCO and related expansion project, see Item 13 of this annual report.
	§		The Piceance Creek Gathering System consists of a recently constructed natural gas gathering pipeline located in the Piceance Basin of northwestern Colorado. This pipeline is owned by Piceance Creek Pipeline, LLC, the ownership interests of which we acquired from EnCana Oil & Gas (“EnCana”) in December 2006. The Piceance Creek Gathering System extends from a connection with EnCana’s Great Divide Gathering System located near Parachute, Colorado, northward through the heart of the Piceance Basin to our 1.7 Bcf/d Meeker natural gas treating and processing complex, which is currently under construction. Connectivity to EnCana’s Great Divide Gathering System will provide the Piceance Creek Gathering System with access to natural gas production from the southern portion of the Piceance basin, including production from EnCana’s Mamm Creek field. The Piceance Creek Gathering System was placed in service in January 2007 and began transporting initial volumes of approximately 300 MMcf/d of natural gas.
	§		The San Juan Gathering System serves natural gas producers in the San Juan Basin of New Mexico and Colorado. This system gathers natural gas production from over 10,400 wells in the San Juan Basin and delivers the natural gas to natural gas processing facilities, including our Chaco facility.
	§		The Acadian Gas System purchases, transports, stores and sells natural gas in Louisiana. The Acadian Gas System is comprised of the 577-mile Cypress pipeline, 438-mile Acadian pipeline and the 27-mile Evangeline pipeline. The leased Acadian natural gas storage facility is an integral part of the Acadian Gas System.
			Enterprise Products Partners contributed a direct 66% equity interest in Acadian Gas, which is a subsidiary that owns the Cypress and Acadian pipelines, to Duncan Energy Partners on February 5, 2007. Enterprise Products Partners owns the remaining 34% direct interest in Acadian Gas. For additional information regarding this subsequent event, see “Recent Developments” within this Item 1. Acadian Gas owns a 49.5% indirect interest in the Evangeline pipeline.
	§		The Permian Basin System gathers natural gas from wells in the Permian Basin region of Texas and New Mexico and delivers natural gas into the El Paso Natural Gas, Transwestern and Oasis pipelines. The Permian Basin System is comprised of the 452-mile Waha system and 935-mile Carlsbad system.
	§		The Alabama Intrastate System mainly gathers coal bed methane from wells in the Black Warrior Basin in Alabama. This system is also involved in the purchase, transportation and sale of natural gas.
	§		The Encinal Gathering System gathers natural gas from the Olmos and Wilcox formations and delivers into our Texas Intrastate System, which delivers the natural gas into our south Texas facilities for processing. We acquired this gathering system in connection with the Encinal acquisition in July 2006.
	§		Our Petal and Hattiesburg underground storage facilities are strategically situated to serve the domestic Northeast, Mid-Atlantic and Southeast natural gas markets and are capable of delivering in excess of 1.4 Bcf/d of natural gas into five interstate pipeline systems.

     Offshore Pipelines & Services

     Our Offshore Pipelines & Services business segment includes (i) approximately 1,586 miles of offshore natural gas pipelines strategically located to serve production areas including some of the most active drilling and development regions in the Gulf of Mexico, (ii) approximately 863 miles of offshore Gulf of Mexico crude oil pipeline systems and (iii) six multi-purpose offshore hub platforms located in the Gulf of Mexico with crude oil or natural gas processing capabilities.

     Offshore natural gas pipelines. Our offshore natural gas pipeline systems provide for the gathering and transmission of natural gas from production developments located in the Gulf of Mexico, primarily offshore Louisiana and Texas. Typically, these systems receive natural gas from producers, other pipelines and shippers through system interconnects and transport the natural gas to various downstream pipelines, including major interstate transmission pipelines that access multiple markets in the eastern half of the United States.

     Our revenues from offshore natural gas pipelines are derived from fee-based agreements and are typically based on transportation fees per unit of volume transported (typically in MMBtus) multiplied by the volume delivered. These transportation agreements tend to be long-term in nature, often involving life-of-reserve commitments with firm and interruptible components. We do not take title to the natural gas volumes that are transported on our natural gas pipeline systems; rather, the shipper retains title and the associated commodity price risk.

     Offshore oil pipelines. We own interests in several offshore oil pipeline systems, which are located in the vicinity of oil-producing areas in the Gulf of Mexico. Typically, these systems receive crude oil from offshore production developments, other pipelines or shippers through system interconnects and deliver the oil to either onshore locations or to other offshore interconnecting pipelines.

     The majority of revenues from our offshore crude oil pipelines are derived from purchase and sale arrangements whereby we purchase oil from shippers at various receipt points along our crude oil pipelines for an index-based price (less a price differential) and sell the oil back to the shippers at various redelivery points at the same index-based price. Net revenue recognized from such arrangements is based on a price differential per unit of volume (typically in barrels) multiplied by the volume delivered. In addition, certain of our offshore crude oil pipelines generate revenues based upon a transportation fee per unit of volume (typically in barrels) multiplied by the volume delivered to the customer. A substantial portion of the revenues generated by our offshore crude oil pipeline systems are attributable to (i) production from reserves committed under long-term contracts for the productive life of the relevant field or (ii) contracts for the purchase and sale of crude oil with terms from two to twelve months. The revenues we earn for our services are dependent on the volume of crude oil to be delivered and the amount and term of the reserve commitment by the customer.

     Offshore platforms. We have ownership interests in six multi-purpose offshore hub platforms located in the Gulf of Mexico with crude oil or natural gas processing capabilities. Offshore platforms are critical components of the offshore infrastructure in the Gulf of Mexico, supporting drilling and producing operations, and therefore play a key role in the overall development of offshore oil and natural gas reserves. Platforms are used to: (i) interconnect with the offshore pipeline grid; (ii) provide an efficient means to perform pipeline maintenance; (iii) locate compression, separation, production handling and other facilities; (iv) conduct drilling operations during the initial development phase of an oil and natural gas property; and (v) process off-lease production.

     Revenues from offshore platform services generally consist of demand payments and commodity charges. Demand fees represent charges to customers who use our offshore platforms regardless of the volume the customer delivers to the platform. Revenues from commodity charges are based on a fixed-fee per unit of volume delivered to the platform (typically per MMcf of natural gas or per barrel of crude oil) multiplied by the total volume of each product delivered. Contracts for platform services often include both demand payments and commodity charges, but demand payments generally expire after a contractually fixed period of time and in some instances may be subject to cancellation by customers.

     Seasonality. Our offshore operations exhibit little to no effects of seasonality; however, they may be affected by weather events such as hurricanes and tropical storms in the Gulf of Mexico.

     Competition. Within their market area, our offshore natural gas and oil pipelines compete with other pipelines (both regulated and unregulated systems) primarily on the basis of price (in terms of transportation fees), available capacity and connections to downstream markets. To a limited extent, our competition includes other offshore pipeline systems, built, owned and operated by producers to handle their own production and, as capacity is available, production for others. We compete with other platform service providers on the basis of proximity and access to existing reserves and pipeline systems, as well as costs and rates. Furthermore, our competitors may possess greater capital resources than we have available, which could enable them to address business opportunities more quickly than us.

     Properties. The following table summarizes the significant assets of our Offshore Pipelines & Services business segment at February 5, 2007, all of which are located in the Gulf of Mexico primarily offshore Louisiana and Texas.

    The following information highlights the general use of each of our principal Gulf of Mexico offshore platforms. We operate these offshore platforms with the exception of the Marco Polo platform and East Cameron 373. Anadarko will operate the Independence Hub platform once it becomes operational.

     On a weighted-average basis, utilization rates with respect to natural gas processing capacity of our offshore platforms were approximately 17%, 27% and 33% during the years ended December 31, 2006, 2005 and 2004, respectively. Likewise, utilization rates for our offshore platforms were approximately 19%, 9% and 14%, respectively, in connection with platform crude oil processing capacity. These rates reflect the periods in which we owned an interest in such assets. In addition to the offshore platforms we identified in the preceding table, we own or have an ownership interest in fifteen pipeline junction and service platforms. Our pipeline junction and service platforms do not have any processing capacity.

§

The Independence Hub platform is located in Mississippi Canyon Block 920. This platform will process crude oil and natural gas gathered from production fields in the Atwater Valley, DeSoto Canyon, Lloyd Ridge and Mississippi Canyon areas of the Gulf of Mexico.

	§		The Falcon Nest platform currently processes natural gas from the Falcon field.

     Petrochemical Services

     Our Petrochemical Services business segment includes four propylene fractionation facilities, an isomerization complex, and an octane additive production facility. This segment also includes approximately 679 miles of petrochemical pipeline systems.

     Propylene fractionation. Our propylene fractionation business consists primarily of four propylene fractionation facilities located in Texas and Louisiana, and approximately 609 miles of various propylene pipeline systems. These operations also include an export facility located on the Houston Ship Channel and our petrochemical marketing activities.

     In general, propylene fractionation plants separate refinery grade propylene (a mixture of propane and propylene) into either polymer grade propylene or chemical grade propylene along with by-products of propane and mixed butane. Polymer grade propylene can also be produced from chemical grade propylene feedstock. Chemical grade propylene is also a by-product of olefin (ethylene) production. The demand for polymer grade propylene is attributable to the manufacture of polypropylene, which has a variety of end uses, including packaging film, fiber for carpets and upholstery and molded plastic parts for appliance, automotive, houseware and medical products. Chemical grade propylene is a basic petrochemical used in plastics, synthetic fibers and foams.

     Results of operations for our polymer grade propylene plants are generally dependent upon toll processing arrangements and petrochemical marketing activities. These processing arrangements typically include a base-processing fee per gallon (or other unit of measurement) subject to adjustment for changes in natural gas, electricity and labor costs, which are the primary costs of propylene fractionation and isomerization operations. Our petrochemical marketing activities generate revenues from the sale and delivery of products obtained through our processing activities and purchases from third parties on the open market. In general, we sell our petrochemical products at market-related prices, which may include pricing differentials for such factors as delivery location.

     As part of our petrochemical marketing activities, we have several long-term polymer grade propylene sales agreements. To meet our petrochemical marketing obligations, we have entered into several agreements to purchase refinery grade propylene. To limit the exposure of our petrochemical marketing activities to price risk, we attempt to match the timing and price of our feedstock purchases with those of the sales of end products.

     Isomerization. Our isomerization business includes three butamer reactor units and eight associated deisobutanizer units located in Mont Belvieu, Texas, which comprise the largest commercial isomerization complex in the United States. In addition, this business includes a 70-mile pipeline system used to transport high-purity isobutane from Mont Belvieu, Texas to Port Neches, Texas.

     Our commercial isomerization units convert normal butane into mixed butane, which is subsequently fractionated into normal butane, isobutane and high purity isobutane. Isobutane is used in the production of alkylate for motor gasoline, propylene oxide, isooctane and methyl tertiary butyl ether (“MTBE”). The demand for commercial isomerization services depends upon the industry’s requirements for high purity isobutane and isobutane in excess of naturally occurring isobutane produced from NGL fractionation and refinery operations.

     The results of operation of this business are generally dependent upon the volume of normal and mixed butanes processed and the level of toll processing fees charged to customers. Our isomerization facility provides processing services to meet the needs of third-party customers and our other businesses, including our NGL marketing activities and octane additive production facility.

     Octane enhancement. We own and operate an octane additive production facility located in Mont Belvieu, Texas designed to produce isooctane, which is an additive used in reformulated motor gasoline blends to increase octane, and isobutylene. The facility produces isooctane and isobutylene using feedstocks of high-purity isobutane, which is supplied using production from our isomerization units.

     Prior to mid-2005, the facility produced MTBE. The production of MTBE was primarily driven by oxygenated fuel programs enacted under the federal Clean Air Act Amendments of 1990, which mandated the use of reformulated gasoline in certain areas of the United States. In recent years, MTBE has been detected in water supplies. The major source of ground water contamination appears to be leaks from underground storage tanks. As a result of environmental concerns, several states enacted legislation to ban or significantly limit the use of MTBE in motor gasoline within their jurisdictions. In addition, the Energy Policy Act of 2005 eliminated the requirement of oxygenates in reformulated motor gasoline. As a result of such developments, we modified the facility to produce isooctane and isobutylene. Depending on the outcome of various factors, the facility may be further modified in the future to produce alkylate, another motor gasoline additive.

     Seasonality. Overall, the propylene fractionation business exhibits little seasonality. Our isomerization operations experience slightly higher demand in the spring and summer months due to the demand for isobutane-based fuel additives used in the production of motor gasoline. Likewise, isooctane prices have been stronger during the April to September period of each year, which corresponds with the summer driving season.

     Competition. We compete with numerous producers of polymer grade propylene, which include many of the major refiners and petrochemical companies on the Gulf Coast. Generally, the propylene fractionation business competes in terms of the level of toll processing fees charged and access to pipeline and storage infrastructure. Our petrochemical marketing activities encounter competition from fully integrated oil companies and various petrochemical companies. Our petrochemical marketing competitors have varying levels of financial and personnel resources and competition generally revolves around price, service, logistics and location.

     In the isomerization market, we compete primarily with facilities located in Kansas, Louisiana and New Mexico. Competitive factors affecting this business include the level of toll processing fees charged, the quality of isobutane that can be produced and access to pipeline and storage infrastructure. We also compete with other octane additive manufacturing companies primarily on the basis of price.

     Properties. The following table summarizes the significant assets of our Petrochemical Services segment at February 5, 2007, all of which we operate.

     We produce polymer grade propylene at our Mont Belvieu location and chemical grade propylene at our BRPC facility. The primary purpose of the BRPC unit is to fractionate refinery grade propylene produced by an affiliate of ExxonMobil Corporation into chemical grade propylene. The production of polymer grade propylene from our Mont Belvieu plants is primarily used in our petrochemical marketing activities. On a weighted-average basis, aggregate utilization rates of our propylene fractionation facilities were approximately 86%, 83% and 86% during the years ended December 31, 2006, 2005 and 2004, respectively. This business segment also includes an above-ground polymer grade propylene storage and export facility located in Seabrook, Texas. This facility can load vessels at rates up to 5,000 barrels per hour.

     The Lou-Tex propylene pipeline is used to transport chemical grade propylene from Sorrento, Louisiana to Mont Belvieu, Texas. The Sabine pipeline is used to transport polymer grade propylene from Port Arthur, Texas to a pipeline interconnect in Cameron Parish, Louisiana. We own these pipelines through our subsidiaries, Lou-Tex Propylene and Sabine Propylene.

     On February 5, 2007, Enterprise Products Partners contributed a direct 66% equity interest in its subsidiaries that own the Lou-Tex Propylene and Sabine Propylene pipelines to Duncan Energy Partners. Enterprise Products Partners owns the remaining 34% direct interest in these subsidiaries. For additional information regarding this subsequent event, see “Recent Developments” within this Item 1.

     The maximum number of barrels that our petrochemical pipelines can transport per day depends upon the operating balance achieved at a given point in time between various segments of the systems. Since the operating balance is dependent upon the mix of products to be shipped and demand levels at various delivery points, the exact capacities of our petrochemical pipelines cannot be determined. We measure the utilization rates of such pipelines in terms of net throughput (i.e., on a net basis in accordance with our ownership interest). Total net throughput volumes for these pipelines were 97 MBPD, 64 MBPD and 71 MBPD during the years ended December 31, 2006, 2005 and 2004, respectively.

     Our octane additive facility currently has an isoocatane production capacity of 12.0 MBPD. The facility was capable of producing only MTBE prior to mid-2005 at a rate up to 15.5 MBPD. On a weighted-average combined product basis, utilization rates for this facility were approximately 45%, 29% and 83% during the years ended December 31, 2006, 2005 and 2004, respectively.

Title to Properties

     Our real property holdings fall into two basic categories: (i) parcels that we and our unconsolidated affiliates own in fee (e.g., we own the land upon which our Mont Belvieu NGL fractionator is constructed) and (ii) parcels in which our interests and those of our unconsolidated affiliates are derived from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities permitting the use of such land for our operations. The fee sites upon which our significant facilities are located have been owned by us or our predecessors in title for many years without any material challenge known to us relating to title to the land upon which the assets are located, and we believe that we have satisfactory title to such fee sites. We and our unconsolidated affiliates have no knowledge of any challenge to the underlying fee title of any material lease, easement, right-of-way, permit or license held by us or to our rights pursuant to any material lease, easement, right-of-way, permit or license, and we believe that we have satisfactory rights pursuant to all of our material leases, easements, rights-of-way, permits and licenses.

Capital Spending

     We are committed to the long-term growth and viability of Enterprise Products Partners. Part of our business strategy involves expansion through business combinations, growth capital projects and investments in joint ventures with industry partners. We believe that we are positioned to continue to grow our system of assets through the construction of new facilities and to capitalize on expected future production increases from such areas as the Piceance Basin of western Colorado, the Greater Green River Basin in Wyoming, Barnett Shale in North Texas, and the deepwater Gulf of Mexico. For a discussion of our capital spending program, see “Capital Spending” included under Item 7 of this annual report.

Regulation

     Interstate Regulation

     Liquids Pipelines. Certain of our crude oil and NGL pipeline systems (collectively referred to as “liquids pipelines”) are interstate common carrier pipelines subject to regulation by the FERC under the Interstate Commerce Act (“ICA”) and the Energy Policy Act of 1992 (“Energy Policy Act”). The ICA prescribes that interstate tariffs must be just and reasonable and must not be unduly discriminatory or confer any undue preference upon any shipper. FERC regulations require that interstate oil pipeline transportation rates be filed with the FERC and posted publicly.

     The ICA permits interested persons to challenge proposed new or changed rates and authorizes the FERC to investigate such rates and to suspend their effectiveness for a period of up to seven months. If, upon completion of an investigation, the FERC finds that the new or changed rate is unlawful, it may require the carrier to refund the revenues in excess of the prior tariff during the term of the investigation. The FERC may also investigate, upon complaint or on its own motion, rates that are already in effect and may order a carrier to change its rates prospectively. Upon an appropriate showing, a shipper may obtain reparations for damages sustained for a period of up to two years prior to the filing of its complaint.

     The Energy Policy Act deemed liquids pipeline rates that were in effect for the twelve months preceding enactment and that had not been subject to complaint, protest or investigation, just and reasonable under the Energy Policy Act (i.e., “grandfathered”). Some, but not all, our interstate liquids pipeline rates are considered grandfathered under the Energy Policy Act. Certain other rates for our interstate liquids pipeline services are charged pursuant to a FERC-approved indexing methodology, which allows a pipeline to charge rates up to a prescribed ceiling that changes annually based on the change from year-to-year in the Producer Price Index for finished goods (“PPI”). A rate increase within the indexed rate ceiling is presumed to be just and reasonable unless a protesting party can demonstrate that the rate increase is substantially in excess of the pipeline’s costs. Effective March 21, 2006, FERC concluded that for the five-year period commencing July 1, 2006, liquids pipelines charging indexed rates may adjust their indexed ceilings annually by the PPI plus 1.3%.

     As an alternative to using the indexing methodology, interstate liquids pipelines may elect to support rate filings by using a cost-of-service methodology, competitive market showings (“Market-Based Rates”) or agreements with all of the pipeline’s shippers that the rate is acceptable.

     Because of the complexity of ratemaking, the lawfulness of any rate is never assured. The FERC uses prescribed rate methodologies for approving regulated tariff rates for transporting crude oil and refined products. These methodologies may limit our ability to set rates based on our actual costs or may delay the use of rates reflecting higher costs. Changes in the FERC’s approved methodology for approving rates could adversely affect us. Adverse decisions by the FERC in approving our regulated rates could adversely affect our cash flow. Challenges to our tariff rates could be filed with the FERC. We believe the transportation rates currently charged by our interstate common carrier liquids pipelines are in accordance with the ICA. However, we cannot predict the rates we will be allowed to charge in the future for transportation services by such pipelines.

     The Lou-Tex Propylene pipeline is an interstate common carrier pipeline regulated under the ICA by the Surface Transportation Board (“STB”), a part of the United States Department of Transportation. If the STB finds that a carrier’s rates are not just and reasonable or are unduly discriminatory or preferential, it may prescribe a reasonable rate. In determining a reasonable rate, the STB will consider, among other factors, the effect of the rate on the volumes transported by that carrier, the carrier’s revenue needs and the availability of other economic transportation alternatives.

     The STB does not need to provide rate relief unless shippers lack effective competitive alternatives. If the STB determines that effective competitive alternatives are not available and a pipeline holds market power, then we may be required to show that our rates are reasonable.

     Natural Gas Pipelines. Our interstate natural gas pipelines and storage facilities are regulated by the FERC under the Natural Gas Act of 1938 (“NGA”). Under the NGA, the rates for service on these interstate facilities must be just and reasonable and not unduly discriminatory. We operate these interstate facilities pursuant to tariffs which set forth terms and conditions of service. These tariffs must be filed with and approved by the FERC pursuant to its regulations and orders. Our tariff rates may be lowered by the FERC, on its own initiative, or as a result of challenges to the rates by third parties if they are found unlawful and the FERC could require refunds of amounts collected under such unlawful rates. Our rates are derived based on a cost-of-service methodology.

     One element of the FERC’s cost-of-service methodology as it affects partnerships such as ours is an income tax allowance. Pursuant to an order on remand of a decision by the U.S. Court of Appeals for the District of Columbia Circuit in BP West Coast, LLC v. FERC and a policy statement regarding income tax allowance issued by the FERC, the FERC will permit a pipeline to include in cost-of-service a tax allowance to reflect actual or potential tax liability on its public utility income attributable to all partnership or limited liability company interests if the ultimate owner of the interest has an actual or potential income tax liability on such income. Whether a pipeline’s owners have such actual or potential income tax liability will be reviewed by the FERC on a case by case basis. Both the FERC’s income tax allowance policy and its initial application in an individual pipeline proceeding are being challenged in the court of appeals.

     The FERC’s authority over companies that provide natural gas pipeline transportation or storage services also includes (i) certification, construction, and operation of new facilities; (ii) the acquisition, extension, disposition or abandonment of such facilities; (iii) the maintenance of accounts and records; (iv) the initiation, extension and discontinuation of covered services; and (v) various other matters. In addition, pursuant to the Energy Policy Act of 2005, the NGA and the Natural Gas Policy Act of 1978 (“NGPA”) were amended to increase civil and criminal penalties for any violation of the NGA, NGPA and any rules, regulations or orders of the FERC up to $1 million per day per violation.

     Offshore Pipelines. Our offshore pipeline systems are subject to federal regulation under the Outer Continental Shelf Lands Act (“OCSLA”), which requires that all pipelines operating on or across the outer continental shelf provide nondiscriminatory transportation service.

     Intrastate Regulation

     Enterprise Products Partners’ intrastate NGL and natural gas pipelines are subject to regulation in many states, including Alabama, Colorado, Louisiana, Mississippi, New Mexico and Texas. Certain of our intrastate pipelines are subject to regulation by the FERC under the NGPA and provide transportation and storage service pursuant to Section 311 of the NGPA and the FERC’s regulations. Under Section 311 of the NGPA, an intrastate pipeline company may transport gas for an interstate pipeline or any local distribution company served by an interstate pipeline. We are required to provide these services on an open and nondiscriminatory basis. The rates for 311 service may be established by the FERC or the respective state agency, but may not exceed a fair and equitable rate.

     Certain other of our pipeline systems operate within a single state and provide intrastate pipeline transportation services. These pipeline systems are subject to various regulations and statutes mandated by state regulatory authorities. Although the applicable state statutes and regulations vary, they generally require that intrastate pipelines publish tariffs setting forth all rates, rules and regulations applying to intrastate service, and generally require that pipeline rates and practices be reasonable and nondiscriminatory. Shippers may also challenge our intrastate tariff rates and practices on our pipelines.

Environmental and Safety Matters

     General

     Our operations are subject to multiple environmental obligations and potential liabilities under a variety of federal, state and local laws and regulations. These include, without limitation: the Comprehensive Environmental Response, Compensation, and Liability Act; the Resource Conservation and Recovery Act; the Clean Air Act; the Federal Water Pollution Control Act or the Clean Water Act; the Oil Pollution Act; and analogous state and local laws and regulations. Such laws and regulations affect many aspects of our present and future operations, and generally require us to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals, with respect to air emissions, water quality, wastewater discharges, and solid and hazardous waste management. Failure to comply with these requirements may expose us to fines, penalties and/or interruptions in our operations that could influence our results of operations. If an accidental leak, spill or release of hazardous substances occurs at a facility that we own, operate or otherwise use, or where we send materials for treatment or disposal, we could be held jointly and severally liable for all resulting liabilities, including investigation, remedial and clean-up costs. Likewise, we could be required to remove or remediate previously disposed wastes or property contamination, including groundwater contamination. Any or all of this could materially affect our results of operations and cash flows.

     We believe our operations are in material compliance with applicable environmental and safety laws and regulations, other than certain matters discussed under Item 3 of this annual report, and that compliance with existing environmental and safety laws and regulations are not expected to have a material adverse effect on our financial position, results of operations or cash flows. Environmental and safety laws and regulations are subject to change. The clear trend in environmental regulation is to place more

restrictions and limitations on activities that may be perceived to affect the environment, and thus there can be no assurance as to the amount or timing of future expenditures for environmental regulation compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. Revised or additional regulations that result in increased compliance costs or additional operating restrictions, particularly if those costs are not fully recoverable from our customers, could have a material adverse effect on our business, financial position, results of operations and cash flows.

     Water

     The Federal Water Pollution Control Act of 1972, as renamed and amended as the Clean Water Act (“CWA”), and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants into navigable waters of the United States, as well as state waters. Permits must be obtained to discharge pollutants into these waters. The Clean Water Act imposes substantial potential liability for the removal and remediation of pollutants.

     The primary federal law for oil spill liability is the Oil Pollution Act of 1990 (“OPA”), which addresses three principal areas of oil pollution — prevention, containment and cleanup, and liability. OPA subjects owners of certain facilities to strict, joint and potentially unlimited liability for containment and removal costs, natural resource damages and certain other consequences of an oil spill, where such spill is into navigable waters, along shorelines or in the exclusive economic zone of the U.S. Any unpermitted release of petroleum or other pollutants from our operations could also result in fines or penalties. OPA applies to vessels, offshore platforms and onshore facilities, including terminals, pipelines and transfer facilities. In order to handle, store or transport oil, shore facilities are required to file oil spill response plans with the United States Coast Guard, the United States Department of Transportation Office of Pipeline Safety (“OPS”) or the EPA, as appropriate.

     Some states maintain groundwater protection programs that require permits for discharges or operations that may impact groundwater conditions. Contamination resulting from spills or releases of petroleum products is an inherent risk within our industry. To the extent that groundwater contamination requiring remediation exists along our pipeline systems as a result of past operation, we believe any such contamination could be controlled or remedied without having a material adverse effect on our financial position, but such costs are site specific and we cannot predict that the effect will not be material in the aggregate.

     Air Emissions

     Our operations are subject to the Federal Clean Air Act (the “Clean Air Act”) and comparable state laws and regulations. These laws and regulations regulate emissions of air pollutants from various industrial sources, including our facilities, and also impose various monitoring and reporting requirements. Such laws and regulations may require that we obtain pre-approval for the construction or modification of certain projects or facilities expected to produce air emissions or result in the increase of existing air emissions, obtain and strictly comply with air permits containing various emissions and operational limitations, or utilize specific emission control technologies to limit emissions.

     Our permits and related compliance obligations under the Clean Air Act, as well as recent or soon to be adopted changes to state implementation plans for controlling air emissions in regional, non-attainment areas, may require our operations to incur capital expenditures to add to or modify existing air emission control equipment and strategies. In addition, some of our facilities are included within the categories of hazardous air pollutant sources, which are subject to increasing regulation under the Clean Air Act and many state laws. Our failure to comply with these requirements could subject us to monetary penalties, injunctions, conditions or restrictions on operations, and enforcement actions. We may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operating permits and approvals for air emissions. We believe, however, that such requirements will not have a material adverse effect on our operations, and the requirements are not expected to be any more burdensome to us than to any other similarly situated companies.

     Congress is currently considering proposed legislation directed at reducing “greenhouse gas emissions.” It is not possible at this time to predict how legislation that may be enacted to address greenhouse gas emissions would impact our business. However, future laws and regulations could result in increased compliance costs or additional operating restrictions, and could have a material adverse effect on our business, financial position, results of operations and cash flows.

     Solid Waste

     In our normal operations, we generate hazardous and non-hazardous solid wastes, including hazardous substances, that are subject to the requirements of the federal Resource Conservation and Recovery Act (“RCRA”) and comparable state laws, which impose detailed requirements for the handling, storage treatment and disposal of hazardous and solid waste. We also utilize waste minimization and recycling processes to reduce the volumes of our waste. Amendments to RCRA required the EPA to promulgate regulations banning the land disposal of all hazardous wastes unless the waste meets certain treatment standards or the land-disposal method meets certain waste containment criteria.

     Environmental Remediation

     The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as “Superfund,” imposes liability, without regard to fault or the legality of the original act, on certain classes of persons who contributed to the release of a “hazardous substance” into the environment. These persons include the owner or operator of a facility where a release occurred, transporters that select the site of disposal of hazardous substances and companies that disposed of or arranged for the disposal of any hazardous substances found at a facility. Under CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also authorizes the EPA and, in some instances, third parties to take actions in response to threats to the public health or the environment and to seek to recover the costs they incur from the responsible classes of persons. It is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. In the course of our operations, our pipeline systems generate wastes that may fall within CERCLA’s definition of a “hazardous substance.” In the event a disposal facility previously used by us requires clean up in the future, we may be responsible under CERCLA for all or part of the costs required to clean up sites at which such wastes have been disposed.

     Pipeline Safety Matters

     We are subject to regulation by the United States Department of Transportation (“DOT”) under the Accountable Pipeline and Safety Partnership Act of 1996, sometimes referred to as the Hazardous Liquid Pipeline Safety Act (“HLPSA”), and comparable state statutes relating to the design, installation, testing, construction, operation, replacement and management of our pipeline facilities. The HLPSA covers petroleum and petroleum products. The HLPSA requires any entity that owns or operates pipeline facilities to (i) comply with such regulations, (ii) permit access to and copying of records, (iii) file certain reports and (iv) provide information as required by the Secretary of Transportation. We believe that we are in material compliance with these HLPSA regulations.

     We are subject to the DOT regulation requiring qualification of pipeline personnel. The regulation requires pipeline operators to develop and maintain a written qualification program for individuals performing covered tasks on pipeline facilities. The intent of this regulation is to ensure a qualified work force and to reduce the probability and consequence of incidents caused by human error. The regulation establishes qualification requirements for individuals performing covered tasks. We believe that we are in material compliance with these DOT regulations.

     We are also subject to the DOT Integrity Management regulations, which specify how companies should assess, evaluate, validate and maintain the integrity of pipeline segments that, in the event of a release, could impact High Consequence Areas (“HCAs”). HCAs are defined to include populated areas,

unusually sensitive environmental areas and commercially navigable waterways. The regulation requires the development and implementation of an Integrity Management Program (“IMP”) that utilizes internal pipeline inspection, pressure testing, or other equally effective means to assess the integrity of HCA pipeline segments. The regulation also requires periodic review of HCA pipeline segments to ensure adequate preventative and mitigative measures exist and that companies take prompt action to address integrity issues raised by the assessment and analysis. In compliance with these DOT regulations, we identified our HCA pipeline segments and have developed an IMP. We believe that the established IMP meets the requirements of these DOT regulations.

     Risk Management Plans

     We are subject to the EPA’s Risk Management Plan (“RMP”) regulations at certain facilities. These regulations are intended to work with the Occupational Safety and Health Act (“OSHA”) Process Safety Management regulations (see “Safety Matters” below) to minimize the offsite consequences of catastrophic releases. The regulations required us to develop and implement a risk management program that includes a five-year accident history, an offsite consequence analysis process, a prevention program and an emergency response program. We believe we are operating in material compliance with our risk management program.

     Safety Matters

     Certain of our facilities are also subject to the requirements of the federal OSHA and comparable state statutes. We believe we are in material compliance with OSHA and state requirements, including general industry standards, record keeping requirements and monitoring of occupational exposures.

     We are subject to OSHA Process Safety Management (“PSM”) regulations, which are designed to prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals. These regulations apply to any process which involves a chemical at or above the specified thresholds or any process which involves certain flammable liquid or gas. We believe we are in material compliance with the OSHA PSM regulations.

     The OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require us to organize and disclose information about the hazardous materials used in our operations. Certain parts of this information must be reported to employees, state and local governmental authorities and local citizens upon request.

Employees

     As of December 31, 2006, approximately 1,900 persons spend 100% of their time engaged in the management and operations of our business, and 100% of the cost for their services is reimbursed to EPCO under an administrative services agreement, except for approximately 80 persons employed and paid directly by Dixie. In addition, approximately 1,100 persons assigned to EPCO’s shared service organizations spend all or a portion of their time engaged in our business. The cost for their services is reimbursed to EPCO under an administrative services agreement (see Item 13) and is generally based on the percentage of time such employees perform services on our behalf during the year. All of the foregoing persons, except the approximately 80 who are employed directly by Dixie, are employees of EPCO. In addition to the EPCO employees, there are approximately 150 contract maintenance and other various contract personnel engaged in our business. For additional information regarding our relationship with EPCO, see Item 13 of this annual report.

Item 1A. Risk Factors.

     An investment in our units involves certain risks. If any of these risks were to occur, our business, results of operations, cash flows and financial condition could be materially adversely affected. In that case, the trading price of our units could decline, and you could lose part or all of your investment.

     The following section lists some, but not all, of the key risk factors that may have a direct impact on our business, results of operations, cash flows and financial condition. The items are not listed in terms of importance or level of risk.

Risks Inherent in an Investment in Us

The parent company’s operating cash flow is derived primarily from cash distributions it receives from Enterprise Products Partners.

     The parent company’s operating cash flow is derived primarily from cash distributions it receives from Enterprise Products Partners. The amount of cash that Enterprise Products Partners can distribute to its partners, including us, each quarter principally depends upon the amount of cash it generates from its operations, which will fluctuate from quarter to quarter based on, among other things, the:

	§		amount of hydrocarbons transported in its gathering and transmission pipelines;
	§		throughput volumes in its processing and treating operations;
	§		fees it charges and the margins it realizes for its services;
	§		price of natural gas;
	§		relationships among crude oil, natural gas and NGL prices;
	§		fluctuations in its working capital needs;
	§		level of its operating costs, including reimbursements to its general partner; and
	§		prevailing economic conditions.

     In addition, the actual amount of cash Enterprise Products Partners will have available for distribution will depend on other factors, including:

	§		the level of sustaining capital expenditures it makes;
	§		the cost of any capital projects and acquisitions;

	§		its debt service requirements and restrictions contained in its obligations for borrowed money; and
	§		the amount of cash reserves established by Enterprise Products GP for the proper conduct of Enterprise Products Partners’ business.

     Because of these factors, Enterprise Products Partners may not have sufficient available cash each quarter to continue paying distributions at its current level of $0.47 per unit. Furthermore, the amount of cash that Enterprise Products Partners has available for distribution depends primarily upon its cash flow, including cash flow from financial reserves and working capital borrowings, and is not solely a function of profitability, which will be affected by non-cash items such as depreciation, amortization and provisions for asset impairments. As a result, Enterprise Products Partners may be able to make cash distributions during periods when it records losses and may not be able to make cash distributions during periods when it records net income. See “Risks Related to Enterprise Products Partners’ Business” included within this Item 1A for a discussion of further risks affecting Enterprise Products Partners’ ability to generate distributable cash flow.

In the future, we may not have sufficient cash to pay distributions at our current distribution level or to increase distributions.

     Because our primary source of operating cash flow currently consists of cash distributions from Enterprise Products Partners, the amount of distributions we are able to make to our unitholders may fluctuate based on the level of distributions Enterprise Products Partners makes to its partners. We cannot assure you that Enterprise Products Partners will continue to make quarterly distributions at its current level of $0.47 per unit or increase its quarterly distributions in the future. In addition, while we would expect to increase or decrease distributions to our unitholders if Enterprise Products Partners increases or decreases distributions to us, the timing and amount of such changes in distributions, if any, will not necessarily be comparable to the timing and amount of any changes in distributions made by Enterprise Products Partners to us. Factors such as capital contributions, debt service requirements, general, administrative and other expenses, reserves for future distributions and other cash reserves established by the board of directors of EPE Holdings may affect the distributions we make to our unitholders. Prior to making any distributions to our unitholders, we will reimburse EPE Holdings and its affiliates for all direct and indirect expenses incurred by them on our behalf. EPE Holdings has the sole discretion to determine the amount of these reimbursed expenses. The reimbursement of these expenses, in addition to the other factors listed above, could adversely affect the level of distributions we make to our unitholders. We cannot guarantee that in the future we will be able to pay distributions or that any distributions we do make will be at or above our current quarterly distribution of $0.35 per unit. The actual amount of cash that is available for distribution to our unitholders will depend on numerous factors, many of which are beyond our control or the control of EPE Holdings.

Restrictions in our credit facility could limit our ability to make distributions to our unitholders.

     Our credit facility contains covenants limiting our ability to take certain actions. This credit facility also contains covenants requiring us to maintain certain financial ratios. We are prohibited from making any distribution to our unitholders if such distribution would cause an event of default or otherwise violate a covenant under this credit facility. For more information about our credit facility, see Note 14 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Our unitholders do not elect our general partner or vote on our general partner’s officers or directors. Affiliates of our general partner currently own a sufficient number of units to block any attempt to remove EPE Holdings as our general partner.

     Unlike the holders of common stock in a corporation, our unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. Our unitholders do not have the ability to elect our general partner or the officers or directors of our general partner. Dan L. Duncan, through his control of Dan Duncan LLC, the sole

member of EPE Holdings, controls our general partner and the election of all of the officers and directors of our general partner.

     Furthermore, if our unitholders are dissatisfied with the performance of our general partner, they will have little ability to remove our general partner or the officers or directors of our general partner. Our general partner may not be removed except upon the vote of the holders of at least 66 2/3% of our outstanding units. Because affiliates of EPE Holdings own more than one-third of our outstanding units, EPE Holdings currently cannot be removed without the consent of such affiliates. As a result, the price at which our units will trade may be lower because of the absence or reduction of a takeover premium in the trading price.

We may issue an unlimited number of limited partner interests without the consent of our unitholders, which will dilute your ownership interest in us and may increase the risk that we will not have sufficient available cash to maintain or increase our per unit distribution level.

     Our partnership agreement provides that we may issue an unlimited number of limited partner interests without the consent of our unitholders. Such units may be issued on the terms and conditions established in the sole discretion of our general partner. Any issuance of additional units would result in a corresponding decrease in the proportionate ownership interest in us represented by, and could adversely affect market price of, units outstanding prior to such issuance. The payment of distributions on these additional units may increase the risk that we will be unable to maintain or increase our current quarterly distribution.

The market price of our units could be adversely affected by sales of substantial amounts of our units in the public markets, including sales by our existing unitholders.

     Sales by any of our existing unitholders of a substantial number of our units in the public markets, or the perception that such sales might occur, could have a material adverse effect on the price of our units or could impair our ability to obtain capital through an offering of equity securities. We do not know whether any such sale would be made in the public market or in a private placement, nor do we know what impact such potential or actual sales would have on our unit price in the future.

Risks arising in connection with the execution of our business strategy may adversely affect our ability to make or increase distributions and/or the market price of our units.

     In addition to seeking to maximize distributions from Enterprise Products Partners, a principal focus of our business strategy includes acquiring general partner interests and associated incentive distribution rights and limited partner interests in publicly traded partnerships and, subject to our business opportunity agreements, acquiring assets and businesses that may or may not relate to Enterprise Products Partners’ business. However, we may not be able to grow through acquisitions if we are unable to identify attractive acquisition opportunities or acquire identified targets. In addition, increased competition for acquisition opportunities may increase our cost of making acquisitions or cause us to refrain from making acquisitions.

     If we are able to make future acquisitions, we may not be successful in integrating our acquisitions into our existing or future assets and businesses. Risks related to our acquisition strategy include but not limited to:

	§		the creation of conflicts of interests and competing fiduciary obligations that may inhibit our ability to grow or make additional acquisitions;
	§		additional or increased regulatory or compliance obligations, including financial reporting obligations;

	§		delays or unforeseen operational difficulties or diminished financial performance associated with the integration of new acquisitions, and the resulting delayed or diminished cash flows from such acquisitions;
	§		inefficiencies and complexities that may arise due to unfamiliarity with new assets, businesses or markets;
	§		conflicts with regard to the sharing of management responsibilities and allocation of time among overlapping officers, directors and other personnel;
	§		the inability to hire, train and retain qualified personnel to manage and operate our growing business; and
	§		the inability to obtain required financing for our existing business and new investment opportunities.

     To the extent we pursue an acquisition that causes us to incur unexpected costs, or that fails to generate expected returns, our results of operations, cash flows and financial condition may be adversely affected, and our ability to make distributions and/or the market price of our units may be negatively impacted.

The control of our general partner may be transferred to a third party without unitholder consent.

     Our general partner may transfer its general partner interest in us to a third party in a merger or in a sale of all or substantially all of its assets without the consent of our unitholders. Furthermore, there is no restriction in our partnership agreement on the ability of Dan Duncan LLC, as the sole member of EPE Holdings, to sell or transfer all or part of its ownership interest in EPE Holdings to a third party. The new owner of our general partner would then be in a position to replace the directors and officers of EPE Holdings.

All of our units and substantially all of the common units of Enterprise Products Partners that are owned by EPCO and its affiliates, other than Dan Duncan LLC and certain trusts affiliated with Dan L. Duncan, are pledged as security under the credit facility of an affiliate of EPCO. Upon an event of default under this credit facility, a change in ownership or control of us or Enterprise Products Partners could result.

     All of our units and substantially all of the common units of Enterprise Products Partners (other than the 13,454,498 common units we own) that are owned or controlled by EPCO and its affiliates, other than Dan Duncan LLC and certain trusts affiliated with Dan L. Duncan, are pledged as security under a credit facility of EPCO Holdings, Inc., a wholly owned subsidiary of EPCO. This credit facility contains customary and other events of default relating to certain defaults of the borrower, us, Enterprise Products Partners and other affiliates of EPCO. Upon an event of default, a change in control or ownership of us or Enterprise Products Partners could result.

All of our assets are pledged under our credit facility.

     The 13,454,498 common units of Enterprise Products Partners and the 100% membership interest in Enterprise Products GP owned by us are pledged as security under our credit facility. Our credit facility contains customary and other events of default. Upon an event of default, the lenders under our credit facility could foreclose on our assets, which would have a material adverse effect on our business, financial condition and results of operations.

Our general partner has a limited call right that may require you to sell your units at an undesirable time or price.

     If at any time our general partner and its affiliates own more than 90% of our outstanding units, our general partner will have the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the units held by unaffiliated persons at a price not less than their then-current market price. As a result, our unitholders may be required to sell their units at an undesirable time or price and may not receive any return on their investment. Our unitholders may also incur a tax liability upon a sale of their units. At December 31, 2006, affiliates of EPE Holdings, including the Employee Partnerships, owned approximately 86.5% of our units.

We depend on the leadership and involvement of Dan L. Duncan and other key personnel for the success of our businesses.

     We depend on the leadership, involvement and services of Dan L. Duncan, the founder of EPCO and the chairman of each of EPE Holdings and Enterprise Products GP. Mr. Duncan has been integral to the our success and the success of EPCO due in part to his ability to identify and develop business opportunities, make strategic decisions and attract and retain key personnel. The loss of his leadership and involvement or the services of any key members of our senior management team could have a material adverse effect on our business, results of operations, cash flows, market price of our securities and financial condition.

An increase in interest rates may cause the market price of our units to decline.

     As interest rates rise, the ability of investors to obtain higher risk-adjusted rates of return by purchasing government-backed debt securities may cause a corresponding decline in demand for riskier investments generally, including yield-based equity investments such as publicly traded limited partnership interests. Reduced demand for our units resulting from investors seeking other more favorable investment opportunities may cause the trading price of our units to decline.

Enterprise Products Partners may issue additional common units, which may increase the risk that Enterprise Products Partners will not have sufficient available cash to maintain or increase it’s per unit distribution level.

     Enterprise Products Partners has wide latitude to issue additional common units on terms and conditions established by Enterprise Products GP. The payment of distributions on those additional common units may increase the risk that Enterprise Products Partners will be unable to maintain or increase its per unit distribution level, which in turn may impact the available cash that we have to distribute to our unitholders.

Unitholders’ liability as a limited partner may not be limited, and our unitholders may have to repay distributions or make additional contributions to us under certain circumstances.

     As a limited partner in a partnership organized under Delaware law, our unitholders could be held liable for our obligations to the same extent as a general partner if they participate in the “control” of our business. EPE Holdings generally has unlimited liability for the obligations of the partnership, except for those contractual obligations of the partnership that are expressly made without recourse to EPE Holdings. Additionally, the limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in many jurisdictions.

     Under certain circumstances, our unitholders may have to repay amounts wrongfully distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, neither we nor Enterprise Products Partners may make a distribution to our unitholders if the distribution would cause our or Enterprise Products Partners’ respective liabilities to exceed the fair value of our respective assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, partners who received the distribution and who knew at the time of the distribution that it violated

Delaware law will be liable to the partnership for the distribution amount. Liabilities to partners on account of their partnership interest and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

If in the future we cease to manage and control Enterprise Products Partners through our direct or indirect ownership of Enterprise Products GP, we may be deemed to be an investment company under the Investment Company Act of 1940.

     If we cease to manage and control Enterprise Products Partners and are deemed to be an investment company under the Investment Company Act of 1940, we would either have to register as an investment company under the Investment Company Act, obtain exemptive relief from the Securities and Exchange Commission, or modify our organizational structure or our contract rights to fall outside the definition of an investment company. Registering as an investment company could, among other things, materially limit our ability to engage in transactions with affiliates, including the purchase and sale of certain securities or other property to or from our affiliates, restrict our ability to borrow funds or engage in other transactions involving leverage and require us to add additional directors who are independent of us or our affiliates.

Our partnership agreement restricts the rights of unitholders owning 20% or more of our units.

     Our unitholders’ voting rights are restricted by the provision in our partnership agreement generally providing that any units held by a person that owns 20% or more of any class of units then outstanding, other than EPE Holdings and its affiliates, cannot be voted on any matter. In addition, our partnership agreement contains provisions limiting the ability of our unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders’ ability to influence the manner or direction of our management. As a result, the price at which our units will trade may be lower because of the absence or reduction of a takeover premium in the trading price.

Risks Relating to Conflicts of Interest

     Conflicts of interest exist and may arise in the future among us, Enterprise Products Partners, TEPPCO, and our respective general partners and affiliates. Future conflicts of interest may arise among us and the entities represented by any general partner interests we acquire or among Enterprise Products Partners, TEPPCO and such entities.

Conflicts of interest exist and may arise among us, Enterprise Products Partners, TEPPCO and our respective general partners and affiliates and entities affiliated with any general partner interests that we may acquire in the future.

     Conflicts of interest exist and may arise in the future as a result of the relationships among us, Enterprise Products Partners, TEPPCO and our respective general partners and affiliates. EPE Holdings is controlled by Dan Duncan LLC, of which Dan L. Duncan is the sole member. Accordingly, Mr. Duncan has the ability to elect, remove and replace the directors and officers of EPE Holdings. Similarly, through his indirect control of the general partner of each of Enterprise Products Partners and TEPPCO, Mr. Duncan has the ability to elect, remove and replace the directors and officers of the general partner of each of Enterprise Products Partners and TEPPCO. The assets of Enterprise Products Partners and TEPPCO overlap in certain areas, which may result in various conflicts of interest in the future.

     EPE Holdings’ directors and officers have fiduciary duties to manage our business in a manner beneficial to us and our partners. However, all of EPE Holdings’ executive officers and non-independent directors (excluding O.S. Andras) also serve as executive officers or directors of Enterprise Products GP and, as a result, have fiduciary duties to manage the business of Enterprise Products Partners in a manner beneficial to Enterprise Products Partners and its partners. Consequently, these directors and officers may encounter situations in which their fiduciary obligations to Enterprise Products Partners, on the one hand, and us, on the other hand, are in conflict. The resolution of these conflicts may not always be in our best interest or that of our unitholders.

     Future conflicts of interest may arise among us and any entities whose general partner interests we or our affiliates acquire or among Enterprise Products Partners, TEPPCO and such entities. It is not possible to predict the nature or extent of these potential future conflicts of interest at this time, nor is it possible to determine how we will address and resolve any such future conflicts of interest. However, the resolution of these conflicts may not always be in our best interest or that of our unitholders.

If we are presented with certain business opportunities, Enterprise Products Partners (for itself or Duncan Energy Partners) will have the first right to pursue such opportunities.

     Pursuant to an administrative services agreement, we have agreed to certain business opportunity arrangements to address potential conflicts that may arise among us, Enterprise Products Partners and the EPCO Group (which includes EPCO and its affiliates, excluding Enterprise Products GP, Enterprise Products Partners and its subsidiaries (including Duncan Energy Partners), us and EPE Holdings and TEPPCO, its general partner and their controlled affiliates). If a business opportunity in respect of any assets other than equity securities, which we generally define to include general partner interests in publicly traded partnerships and similar interests and associated incentive distribution rights and limited partner interests or similar interests owned by the owner of such general partner or its affiliates, is presented to the EPCO Group, us, EPE Holdings, Enterprise Products GP or Enterprise Products Partners, then Enterprise Products Partners (for itself or Duncan Energy Partners) will have the first right to acquire such assets. The administrative services agreement provides, among other things, that Enterprise Products Partners (for itself or Duncan Energy Partners) will be presumed to desire to acquire the assets until such time as it advises the EPCO Group and us that it has abandoned the pursuit of such business opportunity, and we may not pursue the acquisition of such assets prior to that time. These business opportunity arrangements limit our ability to pursue acquisitions of assets that are not “equity securities.”

Our general partner’s affiliates may compete with us.

     Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. Except as provided in our partnership agreement and subject to certain business opportunity agreements, affiliates of our general partner are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us.

Potential conflicts of interest may arise among our general partner, its affiliates and us. Our general partner and its affiliates have limited fiduciary duties to us and our unitholders, which may permit them to favor their own interests to the detriment of us and our unitholders.

     At December 31, 2006, Dan L. Duncan, EPCO and their controlled affiliates, including the Employee Partnerships, owned approximately 86.5% of our units, and Dan Duncan LLC owned 100% of EPE Holdings. Dan Duncan serves as EPE Holdings’ Chairman as well as the Chairman of Enterprise Products GP. Conflicts of interest may arise among EPE Holdings and its affiliates, including TEPPCO, on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, EPE Holdings may favor its own interests and the interests of its affiliates over the interests of our unitholders. These conflicts include, among others, the following:

	§		EPE Holdings is allowed to take into account the interests of parties other than us, including EPCO, Enterprise Products GP, Enterprise Products Partners and their respective affiliates and any future general partners and limited partnerships acquired in the future in resolving conflicts of interest, which has the effect of limiting its fiduciary duty to our unitholders;
	§		our general partner has limited its liability and reduced its fiduciary duties under our partnership agreement, while also restricting the remedies available to our unitholders for actions that, without these limitations, might constitute breaches of fiduciary duty. As a result of purchasing our units, unitholders consent to various actions and conflicts of interest that might otherwise constitute a breach of fiduciary or other duties under applicable state law;

	§		our general partner determines the amount and timing of our investment transactions, borrowings, issuances of additional partnership securities and reserves, each of which can affect the amount of cash that is available for distribution to our unitholders;
	§		our general partner determines which costs incurred by it and its affiliates are reimbursable by us;
	§		our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered, or from entering into additional contractual arrangements with any of these entities on our behalf, so long as the terms of any such payments or additional contractual arrangements are fair and reasonable to us;
	§		our general partner controls the enforcement of obligations owed to us by it and its affiliates; and
	§		our general partner decides whether to retain separate counsel, accountants or others to perform services for us.

Our partnership agreement limits our general partner’s fiduciary duties to us and our unitholders and restricts the remedies available to our unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty.

    Our partnership agreement contains provisions that reduce the standards to which our general partner would otherwise be held by state fiduciary duty law. For example, our partnership agreement:

	§		permits EPE Holdings to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner. This entitles EPE Holdings to consider only the interests and factors that it desires, and it has no duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or any limited partner;
	§		provides that our general partner is entitled to make other decisions in “good faith” if it reasonably believes that the decision is in our best interests;
	§		generally provides that affiliated transactions and resolutions of conflicts of interest not approved by the Audit, Conflicts and Governance Committee of the board of directors of our general partner and not involving a vote of unitholders must be on terms no less favorable to us than those generally being provided to or available from unrelated third parties or be “fair and reasonable” to us and that, in determining whether a transaction or resolution is “fair and reasonable,” our general partner may consider the totality of the relationships among the parties involved, including other transactions that may be particularly advantageous or beneficial to us; and
	§		provides that our general partner and its officers and directors will not be liable for monetary damages to us, our limited partners or assignees for any acts or omissions unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that the general partner or those other persons acted in bad faith or engaged in fraud, willful misconduct or gross negligence.

    In order to become a limited partner of our partnership, our unitholders are required to agree to be bound by the provisions in the partnership agreement, including the provisions discussed above.

Enterprise Products GP controls Enterprise Products Partners and may influence cash distributed to us.

    Although we are the sole member of Enterprise Products GP, our control over Enterprise Products GP’s actions is limited. The fiduciary duties owed by Enterprise Products GP to Enterprise Products Partners and its unitholders prevent us from influencing Enterprise Products GP to take any action that would benefit us to the detriment of Enterprise Products Partners or its unitholders. For example, Enterprise Products GP makes business determinations on behalf of Enterprise Products Partners that

impact the amount of cash distributed by Enterprise Products Partners to its unitholders and to Enterprise Products GP, which in turn, affects the amount of cash distributions we receive from Enterprise Products Partners and Enterprise Partners GP and consequently, the amount of distributions we can pay to our unitholders.

EPCO’s employees may be subjected to conflicts in managing our business and the allocation of time and compensation costs between our business and the business of EPCO and its other affiliates.

     We have no officers or employees and rely solely on officers of our general partner and employees of EPCO. Certain of our officers are also officers of EPCO and other affiliates of EPCO. These relationships may create conflicts of interest regarding corporate opportunities and other matters, and the resolution of any such conflicts may not always be in our or our unitholders’ best interests. In addition, these overlapping officers allocate their time among us, EPCO and other affiliates of EPCO. These officers face potential conflicts regarding the allocation of their time, which may adversely affect our business, results of operations and financial condition.

     We have entered into an administrative services agreement that governs business opportunities among entities controlled by EPCO, which includes us and our general, Enterprise Products Partners and its general partner, Duncan Energy Partners and its general partner and TEPPCO and its general partner. For information regarding how business opportunities are handled within the EPCO group of companies, see Item 13 of this annual report.

     We do not have an independent compensation committee, and aspects of the compensation of our executive officers and other key employees, including base salary, are not reviewed or approved by our independent directors. The determination of executive officer and key employee compensation could involve conflicts of interest resulting in economically unfavorable arrangements for us.

Risks Relating to Enterprise Products Partners’ Business

     Since our cash flows consist exclusively of distributions from Enterprise Products Partners, risks to Enterprise Products Partners’ business are also risks to us. We have set forth below some, but not all, of the key risks to Enterprise Products Partners’ business, the occurrence of which could have negative impact on Enterprise Products Partners’ financial performance and decrease the amount of cash it is able to distribute to us, thereby impacting the amount of cash that we are able to distribute to our unitholders. These key risks are not in terms of importance or level of risk.

Changes in demand for and production of hydrocarbon products may materially adversely affect Enterprise Products Partners’ results of operations, cash flows and financial condition.

     Enterprise Products Partners operates predominantly in the midstream energy sector which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs and crude oil. As such, its results of operations, cash flows and financial condition may be materially adversely affected by changes in the prices of these hydrocarbon products and by changes in the relative price levels among these hydrocarbon products.

      Changes in prices and changes in the relative price levels may impact demand for hydrocarbon products, which in turn may impact production and volumes of product for which Enterprise Products Partners provide services. Enterprise Products Partners may also incur price risk to the extent counterparties do not perform in connection with its marketing of natural gas, NGLs and propylene.

      In the past, the prices of natural gas have been extremely volatile, and Enterprise Products Partners expects this volatility to continue. The NYMEX daily settlement price for natural gas for the prompt month contract in 2004 ranged from a high of $8.75 per MMBtu to a low of $4.57 per MMBtu. In 2005, the same index ranged from a high of $15.38 per MMBtu to a low of $5.79 per MMBtu. In 2006, the same index ranged from a high of $10.63 per MMBtu to a low of $4.20 per MMBtu.

     Generally, the prices of natural gas, NGLs, crude oil and other hydrocarbon products are subject to fluctuations in response to changes in supply, demand, market uncertainty and a variety of additional factors that are impossible to control. These factors include but are not limited to:

	•		the level of domestic production;
	•		the availability of imported oil and natural gas;
	•		actions taken by foreign oil and natural gas producing nations;
	•		the availability of transportation systems with adequate capacity;
	•		the availability of competitive fuels;
	•		fluctuating and seasonal demand for oil, natural gas and NGLs;
	•		the impact of conservation efforts;
	•		the extent of governmental regulation and taxation of production; and
	•		the overall economic environment.

     Enterprise Products Partners is exposed to natural gas and NGL commodity price risk under certain of its natural gas processing and gathering and NGL fractionation contracts that provide for its fees to be calculated based on a regional natural gas or NGL price index or to be paid in-kind by taking title to natural gas or NGLs. A decrease in natural gas and NGL prices can result in lower margins from these contracts, which may materially adversely affect Enterprise Products Partners’ results of operations, cash flows and financial position.

A decline in the volume of natural gas, NGLs and crude oil delivered to Enterprise Products Partners’ facilities could adversely affect its results of operations, cash flows and financial condition.

     Enterprise Products Partners’ profitability could be materially impacted by a decline in the volume of natural gas, NGLs and crude oil transported, gathered or processed at its facilities. A material decrease in natural gas or crude oil production or crude oil refining, as a result of depressed commodity prices, a decrease in exploration and development activities or otherwise, could result in a decline in the volume of natural gas, NGLs and crude oil handled by its facilities.

     The crude oil, natural gas and NGLs available to Enterprise Products Partners’ facilities will be derived from reserves produced from existing wells, which reserves naturally decline over time. To offset this natural decline, Enterprise Products Partners’ facilities will need access to additional reserves. Additionally, some of its facilities will be dependent on reserves that are expected to be produced from newly discovered properties that are currently being developed.

     Exploration and development of new oil and natural gas reserves is capital intensive, particularly offshore in the Gulf of Mexico. Many economic and business factors are beyond Enterprise Products Partners’ control and can adversely affect the decision by producers to explore for and develop new reserves. These factors could include relatively low oil and natural gas prices, cost and availability of equipment and labor, regulatory changes, capital budget limitations, the lack of available capital or the probability of success in finding hydrocarbons. For example, a sustained decline in the price of natural gas and crude oil could result in a decrease in natural gas and crude oil exploration and development activities in the regions where Enterprise Products Partners’ facilities are located. This could result in a decrease in volumes to its offshore platforms, natural gas processing plants, natural gas, crude oil and NGL pipelines, and NGL fractionators, which would have a material adverse affect on Enterprise Products Partners’ results

of operations, cash flows and financial position. Additional reserves, if discovered, may not be developed in the near future or at all.

A decrease in demand for NGL products by the petrochemical, refining or heating industries could materially adversely affect Enterprise Products Partners’ results of operations, cash flows and financial position.

     A decrease in demand for NGL products by the petrochemical, refining or heating industries, whether because of general economic conditions, reduced demand by consumers for the end products made with NGL products, increased competition from petroleum-based products due to pricing differences, adverse weather conditions, government regulations affecting prices and production levels of natural gas or the content of motor gasoline or other reasons, could materially adversely affect Enterprise Products Partners’ results of operations, cash flows and financial position. For example:

     Ethane. Ethane is primarily used in the petrochemical industry as feedstock for ethylene, one of the basic building blocks for a wide range of plastics and other chemical products. If natural gas prices increase significantly in relation to NGL product prices or if the demand for ethylene falls (and, therefore, the demand for ethane by NGL producers falls), it may be more profitable for natural gas producers to leave the ethane in the natural gas stream to be burned as fuel than to extract the ethane from the mixed NGL stream for sale as an ethylene feedstock.

     Propane. The demand for propane as a heating fuel is significantly affected by weather conditions. Unusually warm winters could cause the demand for propane to decline significantly and could cause a significant decline in the volumes of propane that Enterprise Products Partners transports.

     Isobutane. A reduction in demand for motor gasoline additives may reduce demand for isobutane. During periods in which the difference in market prices between isobutane and normal butane is low or inventory values are high relative to current prices for normal butane or isobutane, its operating margin from selling isobutane could be reduced.

     Propylene. Propylene is sold to petrochemical companies for a variety of uses, principally for the production of polypropylene. Propylene is subject to rapid and material price fluctuations. Any downturn in the domestic or international economy could cause reduced demand for, and an oversupply of propylene, which could cause a reduction in the volumes of propylene that we transport.

Enterprise Products Partners faces competition from third parties in its midstream businesses.

     Even if reserves exist in the areas accessed by Enterprise Products Partners’ facilities and are ultimately produced, Enterprise Products Partners may not be chosen by the producers in these areas to gather, transport, process, fractionate, store or otherwise handle the hydrocarbons that are produced. Enterprise Products Partners competes with others, including producers of oil and natural gas, for any such production on the basis of many factors, including but not limited to:

	§		geographic proximity to the production;
	§		costs of connection;
	§		available capacity;
	§		rates; and
	§		access to markets.

Enterprise Products Partners’ future debt level may limit its flexibility to obtain additional financing and pursue other business opportunities.

    As of December 31, 2006, Enterprise Products Partners had approximately $5.3 billion of consolidated debt outstanding. In addition, as of February 5, 2007, Duncan Energy Partners had approximately $200.0 million outstanding under its credit facility. The amount of Enterprise Products Partners’ future debt could have significant effects on its operations, including, among other things:

	§		a substantial portion of Enterprise Products Partners’ cash flow, including that of Duncan Energy Partners, could be dedicated to the payment of principal and interest on its future debt and may not be available for other purposes, including the payment of distributions on its common units and capital expenditures;
	§		credit rating agencies may view its debt level negatively;
	§		covenants contained in its existing and future credit and debt arrangements will require it to continue to meet financial tests that may adversely affect its flexibility in planning for and reacting to changes in its business, including possible acquisition opportunities;
	§		its ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or such financing may not be available on favorable terms;
	§		it may be at a competitive disadvantage relative to similar companies that have less debt; and
	§		it may be more vulnerable to adverse economic and industry conditions as a result of its significant debt level.

    Enterprise Products Partners’ public debt indentures currently do not limit the amount of future indebtedness that it can create, incur, assume or guarantee. Although its Multi-Year Revolving Credit Facility restricts its ability to incur additional debt above certain levels, any debt it may incur in compliance with these restrictions may still be substantial. For information regarding Enterprise Products Partners’ Multi-Year Revolving Credit Facility, see Note 14 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

    Enterprise Products Partners’ Multi-Year Revolving Credit Facility and each of its indentures for its public debt contain conventional financial covenants and other restrictions. For example, Enterprise Products Partners is prohibited from making distributions to its partners if such distributions would cause an even of default or otherwise violate a covenant under its Multi-Year Revolving Credit Facility. A breach of any of these restrictions by Enterprise Products Partners could permit its lenders or noteholders, as applicable, to declare all amounts outstanding under these debt agreements to be immediately due and payable and, in the case of its Multi-Year Revolving Credit Facility, to terminate all commitments to extend further credit. For additional information regarding Enterprise Products Partners’ Multi-Year Revolving Credit Facility, see Note 14 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

    Enterprise Products Partners’ ability to access capital markets to raise capital on favorable terms will be affected by its debt level, the amount of its debt maturing in the next several years and current maturities, and by prevailing market conditions. Moreover, if the rating agencies were to downgrade Enterprise Products Partners’ credit rating, then Enterprise Products Partners could experience an increase in its borrowing costs, difficulty assessing capital markets or a reduction in the market price of its common units. Such a development could adversely affect Enterprise Products Partners’ ability to obtain financing for working capital, capital expenditures or acquisitions or to refinance existing indebtedness. If Enterprise Products Partners is unable to access the capital markets on favorable terms in the future, it might be forced to seek extensions for some of its short-term securities or to refinance some of its debt obligations through bank credit, as opposed to long-term public debt securities or equity securities. The price and terms upon

which Enterprise Products Partners might receive such extensions or additional bank credit, if at all, could be more onerous than those contained in existing debt agreements. Any such arrangements could, in turn, increase the risk that Enterprise Products Partners’ leverage may adversely affect its future financial and operating flexibility and thereby impact its ability to pay cash distributions at expected rates.

Enterprise Products Partners may not be able to fully execute its growth strategy if it encounters illiquid capital markets or increased competition for investment opportunities.

     Enterprise Products Partners’ strategy contemplates growth through the development and acquisition of a wide range of midstream and other energy infrastructure assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses to enhance its ability to compete effectively and diversifying its asset portfolio, thereby providing more stable cash flow. Enterprise Products Partners regularly considers and enters into discussions regarding, and is currently contemplating and/or pursuing, potential joint ventures, stand alone projects or other transactions that it believes will present opportunities to realize synergies, expand its role in the energy infrastructure business and increase its market position.

     Enterprise Products Partners will require substantial new capital to finance the future development and acquisition of assets and businesses. Any limitations on Enterprise Products Partners’ access to capital will impair its ability to execute this strategy. If the cost of such capital becomes too expensive, Enterprise Products Partners’ ability to develop or acquire accretive assets will be limited. Enterprise Products Partners may not be able to raise the necessary funds on satisfactory terms, if at all. The primary factors that influence Enterprise Products Partners’ initial cost of equity include market conditions, fees it pays to underwriters and other offering costs, which include amounts it pays for legal and accounting services. The primary factors influencing Enterprise Products Partners’ cost of borrowing include interest rates, credit spreads, covenants, underwriting or loan origination fees and similar charges it pays to lenders.

     In addition, Enterprise Products Partners is experiencing increased competition for the types of assets and businesses it has historically purchased or acquired. Increased competition for a limited pool of assets could result in Enterprise Products Partners losing to other bidders more often or acquiring assets at less attractive prices. Either occurrence would limit Enterprise Products Partners’ ability to fully execute its growth strategy. Enterprise Products Partners’ inability to execute its growth strategy may materially adversely affect its ability to maintain or pay higher distributions in the future.

Enterprise Products Partners’ growth strategy may adversely affect its results of operations if it does not successfully integrate the businesses that it acquires or if it substantially increases its indebtedness and contingent liabilities to make acquisitions.

     Enterprise Products Partners’ growth strategy includes making accretive acquisitions. As a result, from time to time, Enterprise Products Partners will evaluate and acquire assets and businesses (either for itself or direct Duncan Energy Partners to do so) that it believes complement its existing operations. Enterprise Products Partners may be unable to integrate successfully businesses it acquires in the future. Enterprise Products Partners may incur substantial expenses or encounter delays or other problems in connection with its growth strategy that could negatively impact its results of operations, cash flows and financial condition. Moreover, acquisitions and business expansions involve numerous risks, including but not limited to:

	§		difficulties in the assimilation of the operations, technologies, services and products of the acquired companies or business segments;
	§		establishing the internal controls and procedures that Enterprise Products Partners is required to maintain under the Sarbanes-Oxley Act of 2002;
	§		managing relationships with new joint venture partners with whom Enterprise Products Partners has not previously partnered;

	§		inefficiencies and complexities that can arise because of unfamiliarity with new assets and the businesses associated with them, including with their markets; and
	§		diversion of the attention of management and other personnel from day-to-day business to the development or acquisition of new businesses and other business opportunities.

     If consummated, any acquisition or investment would also likely result in the incurrence of indebtedness and contingent liabilities and an increase in interest expense and depreciation, depletion and amortization expenses. As a result, Enterprise Products Partners’ capitalization and results of operations may change significantly following an acquisition. A substantial increase in Enterprise Products Partners’ indebtedness and contingent liabilities could have a material adverse effect on its results of operations, cash flows and financial condition. In addition, any anticipated benefits of a material acquisition, such as expected cost savings, may not be fully realized, if at all.

Acquisitions that appear to be accretive may nevertheless reduce Enterprise Products Partners’ cash from operations on a per unit basis.

     Even if Enterprise Products Partners make acquisitions that it believe will be accretive, these acquisitions may nevertheless reduce its cash from operations on a per unit basis. Any acquisition involves potential risks, including, among other things:

	§		mistaken assumptions about volumes, revenues and costs, including synergies;
	§		an inability to integrate successfully the businesses it acquires;
	§		decrease in its liquidity as a result of it using a significant portion of its available cash or borrowing capacity to finance the acquisition;
	§		a significant increase in its interest expense or financial leverage if it incurs additional debt to finance the acquisition;
	§		the assumption of unknown liabilities for which it is not indemnified or for which its indemnity is inadequate;
	§		an inability to hire, train or retain qualified personnel to manage and operate its growing business and assets;
	§		limitations on rights to indemnity from the seller;
	§		mistaken assumptions about the overall costs of equity or debt;
	§		the diversion of management’s and employees’ attention from other business concerns;
	§		unforeseen difficulties operating in new product areas or new geographic areas; and
	§		customer or key employee losses at the acquired businesses.

     If Enterprise Products Partners consummates any future acquisitions, its capitalization and results of operations may change significantly, and you will not have the opportunity to evaluate the economic, financial and other relevant information that it will consider in determining the application of these funds and other resources.

Enterprise Products Partners’ operating cash flows from its capital projects may not be immediate.

     Enterprise Products Partners is engaged in several construction projects involving existing and new facilities for which significant capital has been or will be expended, and Enterprise Products Partners’

operating cash flow from a particular project may not increase until a period of time after its completion. For instance, if Enterprise Products Partners builds a new pipeline or platform or expand an existing facility, the design, construction, development and installation may occur over an extended period of time, and Enterprise Products Partners may not receive any material increase in operating cash flow from that project until a period of time after it is placed in service. If Enterprise Products Partners experiences any unanticipated or extended delays in generating operating cash flow from these projects, Enterprise Products Partners may be required to reduce or reprioritize its capital budget, sell non-core assets, access the capital markets or decrease or limit distributions to unitholders in order to meet its capital requirements.

Enterprise Products Partners’ actual construction, development and acquisition costs could exceed forecasted amounts.

     Enterprise Products Partners has significant expenditures for the development and construction of energy infrastructure assets, including construction and development projects with significant logistical, technological and staffing challenges. Enterprise Products Partners may not be able to complete its projects at the costs it estimated at the time of each project’s initiation or that it currently estimates. For example, material and labor cost trends associated with Enterprise Products Partners’ projects in the Rocky Mountains region have increased since the initiation of these projects due to factors such as higher transportation costs and the availability of construction personnel. Similarly, force majeure events such as hurricanes along the Gulf Coast may cause delays, shortages of skilled labor and additional expenses for these construction and development projects, as were experienced with Hurricanes Katrina and Rita during 2005.

Enterprise Products Partners construction of new assets is subject to regulatory, environmental, political, legal and economic risks, which may result in delays, increased costs or decreased cash flows.

     One of the ways Enterprise Products Partners intend to grow its business is through the construction of new midstream energy assets. The construction of new assets involves numerous operational, regulatory, environmental, political and legal risks beyond its control and may require the expenditure of significant amounts of capital. These potential risks include, among other things, the following:

	§		Enterprise Products Partners may be unable to complete construction projects on schedule or at the budgeted cost due to the unavailability of required construction personnel or materials, accidents, weather conditions or an inability to obtain necessary permits;
	§		Enterprise Products Partners will not receive any material increases in revenues until the project is completed, even though it may have expended considerable funds during the construction phase, which may be prolonged;
	§		Enterprise Products Partners may construct facilities to capture anticipated future growth in production in a region in which such growth does not materialize;
	§		since Enterprise Products Partners is not engaged in the exploration for and development of natural gas reserves, it may not have access to third-party estimates of reserves in an area prior to its constructing facilities in the area. As a result, Enterprise Products Partners may construct facilities in an area where the reserves are materially lower than it anticipate;
	§		where Enterprise Products Partners does rely on third-party estimates of reserves in making a decision to construct facilities, these estimates may prove to be inaccurate because there are numerous uncertainties inherent in estimating reserves; and
	§		Enterprise Products Partners may be unable to obtain rights-of-way to construct additional pipelines or the cost to do so may be uneconomical.

     A materialization of any of these risks could adversely affect Enterprise Products Partners ability to achieve growth in the level of its cash flows or realize benefits from expansion opportunities or construction projects.

     One of the connections between our DEP South Texas NGL Pipeline System and the Mont Belvieu facility is a pipeline Enterprise Products Partners has leased from TEPPCO. The initial term of this lease will expire on September 15, 2007, and if Enterprise Product Partners is unable to construct its planned replacement pipeline or extend the lease, the operations of its DEP South Texas NGL Pipeline System will be interrupted. Enterprise Products Partners cannot assure you that any construction will not be delayed due to government permits, weather conditions or other factors beyond its control.

Enterprise Products Partners may not be able to consummate future public offerings of Duncan Energy Partners on terms that it expects or at all, which would result in less cash available for Enterprise Products Partners to fund its capital spending program.

     Duncan Energy Partners was formed in part to acquire, own and operate midstream energy businesses of Enterprise Products Partners. In the future, Enterprise Products Partners may contribute additional equity interests in its subsidiaries to Duncan Energy Partners and use the proceeds it receives from Duncan Energy Partners to fund its capital spending program. Although Duncan Energy Partners successfully completed its initial public offering in February 2007, there is no guarantee that Duncan Energy Partners will be able to complete future offerings of its securities in amounts that Enterprise Products Partners would expect. If this occurs, Enterprise Products Partners would have less cash available to fund its capital spending program, which could result in less cash distributions to us.

The interruption of distributions to Enterprise Products Partners from its subsidiaries and joint ventures may affect its ability to satisfy its obligations and to make distributions to its partners.

     Enterprise Products Partners is a partnership holding company with no business operations and its operating subsidiaries conduct all of its operations and own all of its operating assets. Its only significant assets are the ownership interests it owns in its subsidiaries and joint ventures. As a result, Enterprise Products Partners depends upon the earnings and cash flow of its subsidiaries and joint ventures and the distribution of that cash in order to meet its obligations and to allow it to make distributions to its partners. The ability of its subsidiaries and joint ventures to make distributions may be restricted by, among other things, the provisions of existing and future indebtedness, applicable state partnership and limited liability company laws and other laws and regulations, including FERC policies. For example, all cash flows from Evangeline are currently used to service its debt.

     In addition, the charter documents governing Enterprise Products Partners’ joint ventures typically allow their respective joint venture management committees sole discretion regarding the occurrence and amount of distributions. Some of the joint ventures in which Enterprise Products Partners participates have separate credit agreements that contain various restrictive covenants. Among other things, those covenants may limit or restrict the joint venture’s ability to make distributions to Enterprise Products Partners under certain circumstances. Accordingly, Enterprise Products Partners’ joint ventures may be unable to make distributions to it at current levels, if at all.

Enterprise Products Partners may be unable to cause its joint ventures to take or not to take certain actions unless some or all of its joint venture participants agree.

     Enterprise Products Partners participates in several joint ventures. Due to the nature of some of these arrangements, the participants have made substantial investments and, accordingly, have required that the relevant charter documents contain certain features designed to provide each participant with the opportunity to participate in the management of the joint venture and to protect its investment, as well as any other assets which may be substantially dependent on or otherwise affected by the activities of that joint venture. These participation and protective features customarily include a corporate governance structure that requires at least a majority-in-interest vote to authorize many basic activities and requires a greater voting interest (sometimes up to 100%) to authorize more significant activities. Examples of these more significant activities are large expenditures or contractual commitments, the construction or acquisition of assets, borrowing money or otherwise raising capital, transactions with affiliates of a joint venture participant, litigation and transactions not in the ordinary course of business, among others. Thus, without the concurrence of joint venture participants with enough voting interests, Enterprise Products

Partners may be unable to cause any of its joint ventures to take or not to take certain actions, even though those actions may be in the best interest of Enterprise Products Partners or the particular joint venture.

     Moreover, any joint venture owner may sell, transfer or otherwise modify its ownership interest in a joint venture, whether in a transaction involving third parties or the other joint venture owners. Any such transaction could result in Enterprise Products Partners being required to partner with different or additional parties.

A natural disaster, catastrophe or other event could result in severe personal injury, property damage and environmental damage, which could curtail Enterprise Products Partners’ operations and otherwise materially adversely affect its cash flow and, accordingly, affect the market price of its common units.

     Some of Enterprise Products Partners’ operations involve risks of personal injury, property damage and environmental damage, which could curtail its operations and otherwise materially adversely affect its cash flow. For example, natural gas facilities operate at high pressures, sometimes in excess of 1,100 pounds per square inch. Enterprise Products Partners also operates oil and natural gas facilities located underwater in the Gulf of Mexico, which can involve complexities, such as extreme water pressure. Virtually all of Enterprise Products Partners’ operations are exposed to potential natural disasters, including hurricanes, tornadoes, storms, floods and/or earthquakes. The location of its assets and its customers’ assets in the U.S. Gulf Coast region makes them particularly vulnerable to hurricane risk.

     If one or more facilities that are owned by Enterprise Products Partners or that deliver oil, natural gas or other products to Enterprise Products Partners are damaged by severe weather or any other disaster, accident, catastrophe or event, Enterprise Products Partners’ operations could be significantly interrupted. Similar interruptions could result from damage to production or other facilities that supply Enterprise Products Partners’ facilities or other stoppages arising from factors beyond its control. These interruptions might involve significant damage to people, property or the environment, and repairs might take from a week or less for a minor incident to six months or more for a major interruption. Additionally, some of the storage contracts that Enterprise Products Partners is a party to obligate Enterprise Products Partners to indemnify its customers for any damage or injury occurring during the period in which the customers’ natural gas is in its possession. Any event that interrupts the revenues generated by Enterprise Products Partners’ operations, or which causes it to make significant expenditures not covered by insurance, could reduce its cash available for paying distributions and, accordingly, adversely affect the market price of its common units.

     Enterprise Products Partners believes that EPCO maintains adequate insurance coverage on behalf of it, although insurance will not cover many types of interruptions that might occur and will not cover amounts up to applicable deductibles. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. For example, change in the insurance markets subsequent to the terrorist attacks on September 11, 2001 and the hurricanes in 2005 have made it more difficult for Enterprise Products Partners to obtain certain types of coverage. As a result, EPCO may not be able to renew existing insurance policies on behalf of Enterprise Products Partners or procure other desirable insurance on commercially reasonable terms, if at all. If Enterprise Products Partners were to incur a significant liability for which it was not fully insured, a material adverse effect on its financial position and results of operations could occur. In addition, the proceeds of any such insurance may not be paid in a timely manner and may be insufficient if such an event were to occur.

An impairment of goodwill and intangible assets could reduce Enterprise Products Partners’ earnings.

     At December 31, 2006, Enterprise Products Partners’ balance sheet reflected $590.5 million of goodwill and $1.0 billion of intangible assets. Goodwill is recorded when the purchase price of a business exceeds the fair market value of the tangible and separately measurable intangible net assets. Generally accepted accounting principles in the United States (“GAAP”) require Enterprise Products Partners to test

goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired. Long-lived assets such as intangible assets with finite useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If Enterprise Products Partners determines that any of its goodwill or intangible assets were impaired, it would be required to take an immediate charge to earnings with a correlative effect on partners’ equity and balance sheet leverage as measured by debt to total capitalization.

Increases in interest rates could materially adversely affect Enterprise Products Partners’ business, results of operations, cash flows and financial condition.

     In addition to Enterprise Products Partners’ exposure to commodity prices, it has significant exposure to increases in interest rates. As of December 31, 2006, it had approximately $5.3 billion of consolidated debt, of which approximately $3.8 billion was at fixed interest rates and approximately $1.5 billion was at variable interest rates, after giving effect to existing interest swap arrangements. From time to time, Enterprise Products Partners may enter into additional interest rate swap arrangements, which could increase its exposure to variable interest rates. As a result, its results of operations, cash flows and financial condition, could be materially adversely affected by significant increases in interest rates.

     An increase in interest rates may also cause a corresponding decline in demand for equity investments, in general, and in particular for yield-based equity investments such as Enterprise Products Partners’ common units. Any such reduction in demand for its common units resulting from other more attractive investment opportunities may cause the trading price of its common units to decline.

The use of derivative financial instruments could result in material financial losses by Enterprise Products Partners.

     Enterprise Products Partners historically has sought to limit a portion of the adverse effects resulting from changes in oil and natural gas commodity prices and interest rates by using financial derivative instruments and other hedging mechanisms from time to time. To the extent that Enterprise Products Partners hedges its commodity price and interest rate exposures, it will forego the benefits we would otherwise experience if commodity prices or interest rates were to change in its favor. In addition, even though monitored by management, hedging activities can result in losses. Such losses could occur under various circumstances, including if a counterparty does not perform its obligations under the hedge arrangement, the hedge is imperfect, or hedging policies and procedures are not followed.

Enterprise Products Partners’ pipeline integrity program may impose significant costs and liabilities on it.

     The U.S. Department of Transportation issued final rules (effective March 2001 with respect to hazardous liquid pipelines and February 2004 with respect to natural gas pipelines) requiring pipeline operators to develop integrity management programs to comprehensively evaluate their pipelines, and take measures to protect pipeline segments located in what the rules refer to as “high consequence areas.” The final rule resulted from the enactment of the Pipeline Safety Improvement Act of 2002. At this time, Enterprise Products Partners cannot predict the ultimate costs of compliance with this rule because those costs will depend on the number and extent of any repairs found to be necessary as a result of the pipeline integrity testing that is required by the rule. Enterprise Products Partners will continue its pipeline integrity testing programs to assess and maintain the integrity of its pipelines. The results of these tests could cause Enterprise Products Partners to incur significant and unanticipated capital and operating expenditures for repairs or upgrades deemed necessary to ensure the continued safe and reliable operation of its pipelines.

Environmental costs and liabilities and changing environmental regulation could materially affect Enterprise Products Partners’ results of operations, cash flows and financial condition.

     Enterprise Products Partners’ operations are subject to extensive federal, state and local regulatory requirements relating to environmental affairs, health and safety, waste management and chemical and petroleum products. Governmental authorities have the power to enforce compliance with applicable

regulations and permits and to subject violators to civil and criminal penalties, including substantial fines, injunctions or both. Certain environmental laws, including CERCLA and analogous state laws and regulations, impose strict, joint and several liability for costs required to cleanup and restore sites where hazardous substances or hydrocarbons have been disposed or otherwise released. Moreover, third parties, including neighboring landowners, may also have the right to pursue legal actions to enforce compliance or to recover for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or other waste products into the environment.

     Enterprise Products Partners will make expenditures in connection with environmental matters as part of normal capital expenditure programs. However, future environmental law developments, such as stricter laws, regulations, permits or enforcement policies, could significantly increase some costs of Enterprise Products Partners’ operations, including the handling, manufacture, use, emission or disposal of substances and wastes.

Federal, state or local regulatory measures could materially adversely affect Enterprise Products Partners’ business, results of operations, cash flows and financial condition.

     The FERC regulates Enterprise Products Partners’ interstate natural gas pipelines and natural gas storage facilities under the Natural Gas Act, and interstate NGL and petrochemical pipelines under the ICA. The STB regulates Enterprise Products Partners’ interstate propylene pipelines. State regulatory agencies regulate its intrastate natural gas and NGL pipelines, intrastate storage facilities and gathering lines.

     Under the Natural Gas Act, the FERC has authority to regulate natural gas companies that provide natural gas pipeline transportation services in interstate commerce. Its authority to regulate those services is comprehensive and includes the rates charged for the services, terms and condition of service and certification and construction of new facilities. The FERC requires that Enterprise Products Partners’ services are provided on a non-discriminatory basis so that all shippers have open access to its pipelines and storage. Pursuant to the FERC’s jurisdiction over interstate gas pipeline rates, existing pipeline rates may be challenged by customer complaint or by the FERC Staff and proposed rate increases may be challenged by protest.

     Enterprise Products Partners has interests in natural gas pipeline facilities offshore from Texas and Louisiana. These facilities are subject to regulation by the FERC and other federal agencies, including the Department of Interior, under the Outer Continental Shelf Lands Act, and by the Department of Transportation’s Office of Pipeline Safety under the Natural Gas Pipeline Safety Act.

     Enterprise Products Partners’ intrastate NGL and natural gas pipelines are subject to regulation in many states, including Alabama, Colorado, Louisiana, Mississippi, New Mexico and Texas, and by the FERC pursuant to Section 311 of the Natural Gas Policy Act. Enterprise Products Partners also has natural gas underground storage facilities in Louisiana, Mississippi and Texas. Although state regulation is typically less onerous than at the FERC, proposed and existing rates subject to state regulation and the provision of services on a non-discriminatory basis are also subject to challenge by protest and complaint, respectively.

     For a general overview of federal, state and local regulation applicable to Enterprise Products Partners’ assets, see Item 1 of this annual report. This regulatory oversight can affect certain aspects of Enterprise Products Partners’ business and the market for its products and could materially adversely affect its cash flows.

Enterprise Products Partners is subject to strict regulations at many of its facilities regarding employee safety, and failure to comply with these regulations could adversely affect its ability to make distributions to us.

     The workplaces associated with Enterprise Products Partners facilities are subject to the requirements of the federal Occupational Safety and Health Act, or OSHA, and comparable state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA hazard

communication standard requires that Enterprise Products Partners maintain information about hazardous materials used or produced in its operations and that it provide this information to employees, state and local governmental authorities and local residents. The failure to comply with OSHA requirements or general industry standards, keep adequate records or monitor occupational exposure to regulated substances could have a material adverse effect on its business, financial condition, results of operations and ability to make distributions to you.

Terrorist attacks aimed at Enterprise Products Partners’ facilities could adversely affect its business, results of operations, cash flows and financial condition.

     Since the September 11, 2001 terrorist attacks on the United States, the United States government has issued warnings that energy assets, including our nation’s pipeline infrastructure, may be the future target of terrorist organizations. Any terrorist attack on Enterprise Products Partners’ facilities or pipelines or those of its customers could have a material adverse effect on its business.

Tax Risks to Our Unitholders

Our tax treatment depends on our status as a partnership for federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the IRS were to treat us as a corporation or if we were to become subject to a material amount of entity-level taxation for state tax purposes, then our cash available for distribution to our unitholders would be substantially reduced.

     The anticipated after-tax benefit of an investment in our units depends largely on our being treated as a partnership for federal income tax purposes. We have not requested, and do not plan to request, a ruling from the IRS (“Internal Revenue Service”) on this matter. The value of our investment in Enterprise Products Partners depends largely on Enterprise Products Partners being treated as a partnership for federal income tax purposes.

     If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which is currently a maximum of 35%. Distributions to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced. This treatment of us as a corporation would result in a material reduction in our anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our units.

     If Enterprise Products Partners were treated as a corporation for federal income tax purposes, it would pay federal income tax on its taxable income at the corporate tax rate. Distributions to us would generally be taxed again as corporate distributions, and no income, gains, losses, deduction or credits would flow through to us. As a result, there would be a material reduction in our anticipated cash flow, likely causing a substantial reduction in the value of our units.

     Current law may change, causing us or Enterprise Products Partners to be treated as a corporation for federal income tax purposes or otherwise subjecting us or Enterprise Products Partners to a material amount of entity level taxation. In addition, because of widespread state budget deficits and other reasons, several states (including Texas) are evaluating ways enhance state-tax collections. For example, our operating subsidiaries will be subject to a newly revised Texas franchise tax (the “Texas Margin Tax”) on the portion of their revenue that is generated in Texas beginning for tax reports due on or after January 1, 2008. Specifically, the Texas Margin Tax will be imposed at a maximum effective rate of 0.7% of the operating subsidiaries’ gross revenue that is apportioned to Texas. If any additional state were to impose a entity-level tax upon us or Enterprise Products Partners as an entity, the cash available for distribution to our unitholders would be reduced.

If the IRS contests the federal income tax positions we take, the market for our units may be adversely impacted, and the costs of any contest will be borne by our unitholders and EPE Holdings.

     The IRS may adopt positions that differ from the position we take, even positions taken with advice of counsel. It may be necessary to resort to administrative or court proceedings to sustain some or all of our counsel’s conclusions or the positions we take. A court may not agree with some or all of our counsel’s conclusions or the positions we take. Any contest with the IRS may materially and adversely impact the market for our units and the price at which they trade. In addition, the costs of any contest with the IRS will result in a reduction in cash available for distribution to our unitholders and our general partner and thus will be borne indirectly by our unitholders and our general partner.

A successful IRS contest of the federal income tax positions taken by Enterprise Products Partners may adversely impact the market for its common units, and the costs of any contest will be borne by Enterprise Products Partners, and therefore indirectly by us and the other unitholders of Enterprise Products Partners.

     The IRS may adopt positions that differ from the positions Enterprise Products Partners takes, even positions taken with the advice of counsel. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions Enterprise Products Partners takes. A court may not agree with all of the positions Enterprise Products Partners takes. Any contest with the IRS may materially and adversely impact the market for Enterprise Products Partners’ common units and the prices at which the common units trade. In addition, the costs of any contest with the IRS will be borne by Enterprise Products Partners and therefore indirectly by us, as a unitholder and as the owner of the general partner of Enterprise Products Partners, and by the other unitholders of Enterprise Products Partners.

Even if our unitholders do not receive any cash distributions from us, they will be required to pay taxes on their share of our taxable income.

     Our unitholders will be required to pay federal income taxes and, in some cases, state and local income taxes on their share of our taxable income, whether or not they receive cash distributions from us. Our unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability that results from their share of our taxable income.

Tax gain or loss on the disposition of our units could be different than expected.

     If our unitholders sell their units, they will recognize gain or loss equal to the difference between the amount realized and their tax basis in those units. Prior distributions in excess of the total net taxable income allocated to a unitholder for a unit, which decreased his tax basis in that unit, will, in effect, become taxable income if the unit is sold at a price greater than such unitholder’s tax basis in that unit, even if the price received is less than such unitholder’s original cost. A substantial portion of the amount realized, whether or not representing gain, may be ordinary income to our unitholders.

Tax-exempt entities and foreign persons face unique tax issues from owning units that may result in adverse tax consequences to them.

     Investment in units by tax-exempt entities, such as individual retirement accounts (known as IRAs), and non-U.S. persons raises issues unique to them. For example, virtually all of our income allocated to organizations exempt from federal income tax, including individual retirement accounts and other retirement plans, will be unrelated business taxable income and will be taxable to them. Distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file United States federal income tax returns and pay tax on their share of our taxable income.

We will treat each purchaser of our units as having the same tax benefits without regard to the units purchased. The IRS may challenge this treatment, which could adversely affect the value of our units.

     Because we cannot match transferors and transferees of units, we will adopt depreciation and amortization positions that may not conform with all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to you. It also could affect the timing of these tax benefits or the amount of gain from your sale of units and could have a negative impact on the value of our units or result in audit adjustments to our unitholders’ tax returns.

Our unitholders will likely be subject to state and local taxes and return filing requirements as a result of investing in our units.

     In addition to federal income taxes, our unitholders will likely be subject to other taxes, such as state and local income taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we or Enterprise Products Partners do business or own property. Our unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements. We or Enterprise Products Partners may own property or conduct business in other states or foreign countries in the future. It is our unitholders’ responsibility to file all federal, state and local tax returns.

Item 1B. Unresolved Staff Comments.

None.

Item 3. Legal Proceedings.

     On occasion, we are named as a defendant in litigation relating to our normal business activities, including regulatory and environmental matters. Although we insure against various business risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify us against liabilities arising from future legal proceedings as a result of our ordinary business activities. We are not aware of any significant litigation, pending or threatened, that we believe may individually have a significant adverse effect on our financial position, cash flows or results of operations.

     A number of lawsuits have been filed by municipalities and other water suppliers against various manufacturers of reformulated gasoline containing methyl tertiary butyl ether (“MTBE”). In general, such suits have not named manufacturers of MTBE as defendants, and there have been no such lawsuits filed against our subsidiary that owns an octane-additive production facility. It is possible, however, that former MTBE manufacturers such as our subsidiary could ultimately be added as defendants in such lawsuits or in new lawsuits.

     We acquired additional ownership interests in our octane-additive production facility from affiliates of Devon Energy Corporation (“Devon”), which sold us its 33.3% interest in 2003, and Sunoco, Inc. (“Sun”), which sold us its 33.3% interest in 2004. As a result of these acquisitions, we own 100% of our Mont Belvieu, Texas octane-additive production facility. Devon and Sun have indemnified us for any liabilities (including potential liabilities as described in the preceding paragraph) that are in respect of periods prior to the date we purchased such interests. There are no dollar limits or deductibles associated with the indemnities we received from Sun and Devon with respect to potential claims linked to the period of time they held ownership interests in our octane-additive production facility.

     On September 18, 2006, Peter Brinckerhoff, a purported unitholder of TEPPCO, filed a complaint in the Court of Chancery of New Castle County in the State of Delaware, in his individual capacity, as a

putative class action on behalf of other unitholders of TEPPCO, and derivatively on behalf of TEPPCO, concerning, among other things, certain transactions involving TEPPCO and us or our affiliates. The complaint names as defendants (i) TEPPCO, its current and certain former directors, and certain of its affiliates; (ii) us and certain of our affiliates, including the parent company of our general partner; (iii) EPCO, Inc.; and (iv) Dan L. Duncan. The complaint alleges, among other things, that the defendants have caused TEPPCO to enter into certain transactions with us or our affiliates that are unfair to TEPPCO or otherwise unfairly favored us or our affiliates over TEPPCO. These transactions are alleged to include the joint venture to further expand the Jonah Gathering System entered into by TEPPCO and one of our affiliates in August 2006 and the sale by TEPPCO to one of our affiliates of the Pioneer gas processing plant in March 2006. The complaint seeks (i) rescission of these transactions or an award of rescissory damages with respect thereto; (ii) damages for profits and special benefits allegedly obtained by defendants as a result of the alleged wrongdoings in the complaint; and (iii) awarding plaintiff costs of the action, including fees and expenses of his attorneys and experts. We believe this lawsuit is without merit and intend to vigorously defend against it. For information regarding our relationship with TEPPCO, see Item 13 of this annual report.

     On February 13, 2007, the Operating Partnership of Enterprise Products Partners received notice from the U.S. Department of Justice (“DOJ”) that it was the subject of a criminal investigation related to an ammonia release in Kingman County, Kansas on October 27, 2004 from a pressurized anhydrous ammonia pipeline owned by a third party, Magellan Ammonia Pipeline, L.P. (“Magellan”). The Operating Partnership is the operator of this pipeline. On February 14, 2007, the Operating Partnership received a letter from the Environment and Natural Resources Division (“ENRD”) of the DOJ regarding this incident and a previous release of ammonia on September 27, 2004 from the same pipeline. The ENRD has indicated that it may pursue civil damages against the Operating Partnership and Magellan as a result of these incidents. Based on this correspondence from the ENRD, the statutory maximum amount of civil fines that could be assessed against the Operating Partnership and Magellan is up to $17.4 million in the aggregate. The Operating Partnership is cooperating with the DOJ and is hopeful that an expeditious resolution acceptable to all parties will be reached in the near future. The Operating Partnership is seeking defense and indemnity under the pipeline operating agreement between it and Magellan. At this time, we do not believe that a final resolution of either the criminal investigation by the DOJ or the civil claims by the ENRD will have a material impact on our consolidated results of operations.

     On October 25, 2006, a rupture in the Magellan Ammonia Pipeline resulted in the release of ammonia near Clay Center, Kansas. We and Magellan are in the process of estimating the repair and remediation costs associated with this release. Environmental remediation efforts continue in and around the site of the release under the supervision and management of affiliates of Magellan. Our operating agreement with Magellan provides the Operating Partnership with an indemnity clause for claims arising from such releases. At this time, we do not believe that this incident will have a material impact on our consolidated results of operations.

     On November 10, 2005, we paid a prorated quarterly distribution of $0.092 per unit. The prorated distribution applied to the 32-day period beginning on August 30, 2005 (the day after we completed our initial public offering) to September 30, 2005 and was based on a declared initial quarterly distribution rate of $0.265 per unit.

     The quarterly cash distributions shown in the table above correspond to cash flows for the quarters indicated. The actual cash distributions (i.e., the payments made to our unitholders) occur within 50 days after the end of such quarter. We expect to fund our quarterly cash distributions to our unitholders primarily with cash provided by operating activities. For additional information regarding our cash flows from operating activities, see “Liquidity and Capital Resources” included under Item 7 of this annual report. Although the payment of cash distributions is not guaranteed, we expect to continue to pay comparable cash distributions in the future.

Overview of Business

     The parent company is the owner of Enterprise Products GP, which is the general partner of Enterprise Products Partners. The primary business purpose of Enterprise Products GP is to manage the affairs and operations of Enterprise Products Partners, which is a North American midstream energy company providing a wide range of services to producers and consumers of natural gas, natural gas liquids (“NGLs”), crude oil, and certain petrochemicals. Enterprise Products Partners is an industry leader in the development of pipeline and other midstream energy infrastructure in the continental United States and Gulf of Mexico. Its midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States, Canada and the Gulf of Mexico with domestic consumers and international markets. Enterprise Products Partners conducts substantially all of its business through a wholly owned subsidiary, Enterprise Products Operating L.P. (the “Operating Partnership”).

     We are owned 99.99% by our limited partners and 0.01% by EPE Holdings. We, EPE Holdings, Enterprise Products GP and Enterprise Products Partners are affiliates and under common control of Dan L. Duncan, the Chairman and controlling shareholder of EPCO. We and Enterprise Products GP have no independent operations outside those of Enterprise Products Partners.

     This annual report contains various forward-looking statements and information based on our beliefs and those of EPE Holdings, our general partner, as well as assumptions made by us and information currently available to us. See “Cautionary Statement Regarding Forward-Looking Information” on page 1 of this annual report.

Basis of Presentation

     The parent company has no separate operating activities apart from those conducted by the Operating Partnership of Enterprise Products Partners. The principal sources of cash flow of the parent company are its investments in limited and general partner ownership interests of Enterprise Products Partners. The parent company’s primary cash requirements are for general and administrative expenses, debt service requirements and distributions to its partners. The parent company’s assets and liabilities are not available to satisfy the debts and other obligations of Enterprise Products Partners.

     In order to fully understand the financial condition and results of operations of the parent company on a standalone basis, we have included discussions of parent company matters apart from those of our consolidated partnership. In general, the discussion of the parent company matters pertains to the period since its initial public offering on August 29, 2005.

     Our historical consolidated financial information presented in this annual report on Form 10-K for periods prior to August 2005 has been presented using the consolidated financial information of our predecessor, Enterprise Products GP and subsidiaries, which includes Enterprise Products Partners. For additional information regarding the basis of presentation of our consolidated financial information, see Note 1 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Recent Developments

     The following information highlights our significant developments since January 1, 2006 through the date of this filing. For additional information regarding the capital projects and acquisitions highlighted below, see “Capital Spending – Significant Recently Announced Growth Capital Projects” included within this Item 7.

§

In February 2007, Duncan Energy Partners L.P. (“Duncan Energy Partners”), a consolidated subsidiary of Enterprise Products Partners, completed an underwritten initial public offering

			of 14,950,000 of its common units. Enterprise Products Partners formed Duncan Energy Partners as a Delaware limited partnership to acquire ownership interests in certain of its midstream energy businesses. For additional information regarding Duncan Energy Partners, see “Other Items – Initial Public Offering of Duncan Energy Partners” included within this Item 7.
	§		In December 2006, we purchased all of the membership interests in Piceance Creek Pipeline, LLC (“Piceance Creek Pipeline”) from an affiliate of the EnCana Corporation (“EnCana”) for $100 million. The assets of Piceance Creek Pipeline consist primarily of a recently constructed 48-mile natural gas gathering pipeline (the “Piceance Creek Gathering System”) located in the Piceance Basin of northwest Colorado. This pipeline will connect to our Meeker natural gas processing plant, which is currently under construction.
	§		In December 2006, Standard & Poor’s raised its credit rating of the Operating Partnership from BB+ to BBB-, which is investment grade, with a stable outlook. As a result of this change, all of the senior unsecured credit ratings of the Operating Partnership are currently at an investment grade level.
	§		In November 2006, we entered into a 30-year agreement with an affiliate of Exxon Mobil Corporation (“ExxonMobil”), to provide gathering, compression, treating and conditioning services for natural gas produced as part of a development program planned by ExxonMobil in the Piceance Basin in Colorado. Under the terms of the agreement, ExxonMobil’s natural gas production from its Piceance Development Project, which encompasses more than 29,000 acres in Rio Blanco County, Colorado, will be dedicated to us. The fee-based agreement includes an option for us to recover NGLs beyond those extracted to condition the gas to meet downstream pipeline specifications.
			To provide these services, we expect to invest approximately $185 million to construct new plant and pipeline facilities to compress the natural gas, treat it to remove impurities, extract NGLs, and deliver gas to the various pipeline transmission systems that serve the region. Construction of the facilities will begin after the receipt of the necessary permits and approvals and is expected to be completed in late 2008.
	§		In November 2006, we announced an expansion of our Texas Intrastate Pipeline with the construction of a 178-mile pipeline (the “Sherman Extension”) that will transport up to 1.1 Bcf/d of natural gas from the growing Barnett Shale area of North Texas. This new pipeline is expected to cost $424.6 million, most of which will be spent in 2008, and be placed in service during the fourth quarter of 2008.
	§		In October 2006, we signed definitive agreements with producers to construct, own and operate an offshore oil pipeline that will provide firm gathering services from the Shenzi production field located in the Southern Green Canyon area of the central Gulf of Mexico.
	§		In September 2006, Enterprise Products Partners sold 12,650,000 of its common units in an underwritten public offering, which generated net proceeds of approximately $320.8 million.
	§		During the third quarter of 2006, the Operating Partnership sold $550 million in principal amount of fixed/floating unsecured junior subordinated notes due 2066 (the “Junior Subordinated Notes A”). For additional information regarding this issuance of debt, see “Liquidity and Capital Resources-Debt Obligations” included within this Item 7.
	§		In August 2006, we became a joint venture partner with TEPPCO involving its Jonah Gas Gathering Company (“Jonah”). Jonah owns the Jonah Gathering System, located in the Greater Green River Basin of southwestern Wyoming. The Jonah Gathering System gathers and transports natural gas produced from the Jonah and Pinedale fields to regional natural gas processing plants, including our Pioneer plant, and major interstate pipelines that deliver

			natural gas to end-use markets. As part of this new joint venture, we and TEPPCO are significantly expanding the Jonah Gathering System (the Phase V expansion project).
	§		In August 2006, we purchased a 220-mile NGL pipeline extending from Corpus Christi, Texas to Pasadena, Texas from ExxonMobil Pipeline Company. The total purchase price for this asset was $97.7 million in cash. This pipeline (in combination with others to be constructed or acquired) will be used to transport NGLs from our South Texas natural gas processing plants to our Mont Belvieu fractionation facilities. Duncan Energy Partners acquired an indirect 66% interest in this pipeline asset on February 5, 2007.
	§		In August 2006, our wholly owned subsidiary, Mid-America Pipeline Company LLC (“Mid-America”), executed new long-term transportation agreements with all but one of its current shippers on its Rocky Mountain pipeline pursuant to terms and conditions of Mid-America’s open season tariff that was accepted by the Federal Energy Regulatory Commission effective August 6, 2006. Under the terms of the new agreements, shippers have committed to transport all of their current and future NGL production from the Rocky Mountains through the Mid-America Pipeline System to either our Hobbs fractionator (expected to be operational by mid-2007) or to Mont Belvieu, Texas via our Seminole Pipeline for a minimum of 10 years and up to a maximum of 20 years. Based on shipper production forecasts and current NGL extraction rates, we expect that these new agreements will fully utilize our Mid-America Pipeline System, including the 50 MBPD Phase I Expansion expected to be placed in-service during the third quarter of 2007.
	§		In July 2006, we signed long-term agreements with CenterPoint Energy Resources Corp. (“CenterPoint Energy”) to provide firm natural gas transportation and storage services to its natural gas utility, primarily in the Houston, Texas metropolitan area. We will provide CenterPoint Energy with an estimated 14 Bcf per year of natural gas beginning in April 2007. Our deliveries to CenterPoint Energy through these new contracts will mark the first time that we have had the opportunity to serve the growing Houston area natural gas market. We are already the primary natural gas service provider to the San Antonio and Austin, Texas markets.
	§		In July 2006, we acquired the Encinal and Canales natural gas gathering systems and their related gathering and processing contracts and other amounts that comprised the South Texas natural gas transportation and processing business of Cerrito Gathering Company, Ltd., an affiliate of Lewis Energy Group, L.P. (“Lewis”). The aggregate value of total consideration we paid or issued to complete this business combination (referred to as the “Encinal acquisition”) was $326.3 million, which includes $145.2 million in cash paid to Lewis and the issuance of 7,115,844 of Enterprise Products Partners’ common units to Lewis.
	§		In April 2006, we announced plans to expand our Houston Ship Channel NGL import and export facility and related pipeline and other assets to accommodate an expected increase in throughput volumes.
	§		In March 2006, we purchased the Pioneer natural gas processing plant and certain related natural gas processing rights from TEPPCO for $38.2 million in cash.
	§		In March 2006, we announced plans to expand our petrochemical assets located in southeast Texas. The plans include the construction of a new propylene fractionator at our Mont Belvieu, Texas facility and the expansion of two refinery grade propylene pipelines.
	§		In March 2006, Enterprise Products Partners sold 18,400,000 of its common units in a public offering, which generated net proceeds of approximately $430 million.
	§		In January 2006, we announced the execution of a minimum 15-year natural gas processing agreement with an affiliate of EnCana. Under this agreement, we have the right to process up to 1.3 Bcf/d of EnCana’s natural gas production from the Piceance Basin area of western

Colorado. To accommodate this production, we began construction of the Meeker natural gas processing facility in Rio Blanco County, Colorado. In addition, we will construct a 50-mile NGL pipeline that will connect our Meeker processing facility to our Mid-America Pipeline System.

Capital Spending

     We are committed to the long-term growth and viability of Enterprise Products Partners. Part of our business strategy involves expansion through business combinations, growth capital projects and investments in joint ventures. We believe that we are positioned to continue to grow our system of assets through the construction of new facilities and to capitalize on expected future production increases from such areas as the Piceance Basin of western Colorado, the Greater Green River Basin in Wyoming, Barnett Shale in North Texas, and the deepwater Gulf of Mexico.

     Management continues to analyze potential acquisitions, joint ventures and similar transactions with businesses that operate in complementary markets or geographic regions. In recent years, major oil and gas companies have sold non-strategic assets in the midstream energy sector in which we operate. We forecast that this trend will continue, and expect independent oil and natural gas companies to consider similar divestitures.

     Based on information currently available, we estimate our consolidated capital spending for 2007 will approximate $1.9 billion, which includes estimated expenditures of $1.7 billion for growth capital projects and acquisitions and $0.2 million for sustaining capital expenditures.

     Our forecast of consolidated capital expenditures is based on our strategic operating and growth plans, which are dependent upon our ability to generate the required funds from either operating cash flows or from other means, including borrowings under debt agreements, issuance of equity by Enterprise Products Partners, and potential divestitures of certain assets to third and/or related parties. Our forecast of capital expenditures may change due to factors beyond our control, such as weather related issues, changes in supplier prices or adverse economic conditions. Furthermore, our forecast may change as a result of decisions made by management at a later date, which may include acquisitions or decisions to take on additional partners.

     Our success in raising capital, including the formation of joint ventures to share costs and risks, continues to be a principal factor that determines how much we can spend. We believe our access to capital resources is sufficient to meet the demands of our current and future operating growth needs, and although we currently intend to make the forecasted expenditures discussed above, we may adjust the timing and amounts of projected expenditures in response to changes in capital markets.
