Partnership Operations, Organization and Basis of Presentation	'
	Note 1.  Partnership Operations and Organization
	General
	We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange ("NYSE") under the ticker symbol "EPD."  We were formed in April 1998 to own and operate certain natural gas liquids ("NGLs") related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products.
	Our integrated midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States ("U.S."), Canada and Gulf of Mexico with domestic consumers and international markets.  Our midstream energy operations include: natural gas gathering, treating, processing, transportation and storage; NGL transportation, fractionation, storage, and import and export terminals (including liquefied petroleum gas or "LPG"); crude oil gathering, transportation, storage and terminals; offshore production platforms; petrochemical and refined products transportation and services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems and in the Gulf of Mexico.  Our assets include approximately 51,000 miles of onshore and offshore pipelines; 200 million barrels ("MMBbls") of storage capacity for NGLs, petrochemicals, refined products and crude oil; and 14 billion cubic feet ("Bcf") of natural gas storage capacity.  In addition, our asset portfolio includes 24 natural gas processing plants, 22 NGL and propylene fractionators, six offshore hub platforms located in the Gulf of Mexico, a butane isomerization complex, NGL import and LPG export terminals, and octane enhancement and high-purity isobutylene production facilities.
	We have five reportable business segments: (i) NGL Pipelines & Services; (ii) Onshore Natural Gas Pipelines & Services; (iii) Onshore Crude Oil Pipelines & Services; (iv) Offshore Pipelines & Services; and (v) Petrochemical & Refined Products Services.
	We are 100% owned by our limited partners from an economic perspective.  We are managed and controlled by Enterprise GP, which has a non-economic general partner interest in us.  We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees.  We have no employees.  All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to an administrative services agreement (the "ASA") or by other service providers.  See Note 12 for information regarding the ASA and other related party matters.

General Accounting Matters	'
	Note 2.  General Accounting Matters
	Our results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of results expected for the full year of 2014.  In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation.  Although we believe the disclosures in these financial statements are adequate and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC").
	These Unaudited Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the Audited Consolidated Financial Statements and Notes thereto included in our annual report on Form 10-K for the year ended December 31, 2013 (the "2013 Form 10-K") filed with the SEC on March 3, 2014.
	See Note 18 for information regarding a two-for-one common unit split announced on July 15, 2014.  All per unit amounts and number of units outstanding in these Unaudited Condensed Consolidated Financial Statements and Notes thereto are presented on a pre-split basis.
	Contingencies
	Certain conditions may exist as of the date our consolidated financial statements are issued, which may result in a loss to us but which will only be resolved when one or more future events occur or fail to occur.  Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the need for accounting recognition or disclosure of these contingencies, and such assessment inherently involves an exercise in judgment.  In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, our management and legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.
	We accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated.  If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued.  We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when it is believed to be only reasonably possible or remote.
	For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, we disclose the nature of the contingency and, if feasible, an estimate of the possible loss or range of loss.
	Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed.  See Note 14 for additional information regarding our contingencies.
	Derivative Instruments
	We use derivative instruments such as futures, swaps, options, forward contracts and other arrangements to manage price risks associated with inventories, firm commitments, interest rates, foreign currencies and certain anticipated future commodity transactions.  To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted.  We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a monthly basis thereafter.  Forecasted transactions are evaluated for the probability of occurrence and are periodically back-tested once the forecasted period has passed to determine whether similarly forecasted transactions are probable of occurring in the future.
	For certain physical forward commodity derivative contracts, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such contracts are not recognized in income.  As a result, the revenues and expenses associated with such physical transactions are recognized during the period when volumes are physically delivered or received.  Physical forward commodity contracts subject to this exception are evaluated for the probability of future delivery and are periodically back-tested once the forecasted period has passed to determine whether similar forward contracts are probable of physical delivery in the future.  See Note 4 for additional information regarding our derivative instruments.
	Estimates
	Preparing our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates that affect amounts presented in the financial statements.  Our most significant estimates relate to (i) the useful lives and depreciation/amortization methods used for fixed and identifiable intangible assets; (ii) measurement of fair value and projections used in impairment testing of fixed and intangible assets (including goodwill); (iii) contingencies; and (iv) revenue and expense accruals.
	Actual results could differ materially from our estimates.  On an ongoing basis, we review our estimates based on currently available information.  Any changes in the facts and circumstances underlying our estimates may require us to update such estimates, which could have a material impact on our consolidated financial statements.
	Recent Accounting Developments
	In May 2014, the Financial Accounting Standards Board ("FASB") and the International Accounting Standards Board finished their joint project to converge U.S. GAAP and International Financial Reporting Standards in the area of revenue recognition.  The resulting accounting standards update eliminates the transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replaces it with a principles based approach for determining revenue recognition.
	The core principle in the new guidance is that a company should recognize revenue in a manner that depicts the transfer of goods or services to customers in an amount that reflects the consideration the company expects to receive for those goods or services.  In order to apply this core principle, companies will apply the following five steps in determining the amount of revenues to recognize:
	§	identify the contract;
	§	identify the performance obligations in the contract;
	§	determine the transaction price;
	§	allocate the transaction price to the performance obligations in the contract; and
	§	recognize revenue when (or as) the performance obligation is satisfied.
	Each of these steps involves judgment and an analysis of the contract's terms and conditions.
	We are continuing to evaluate this recently issued accounting guidance; therefore, we are currently not in a position to estimate its impact on our consolidated financial statements.  The effective date of the new standard is January 1, 2017.  At present, we expect to adopt the new standard using the modified retrospective method.  This modified approach allows us to apply the new standard to (i) all new contracts after the effective date and (ii) all existing contracts as of the effective date through a cumulative adjustment to equity.  Consolidated revenues for periods prior to the effective date would not be retrospectively adjusted.
	Restricted Cash
	Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, crude oil, refined products and NGLs.  Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or deposit requirements change.  At June 30, 2014 and December 31, 2013, our restricted cash amounts were $56.7 million and $65.6 million, respectively.  See Note 4 for information regarding our derivative instruments and hedging activities.

Equity-based Awards	'
	Note 3.  Equity-based Awards
	An allocated portion of the fair value of EPCO's equity-based awards is charged to us under the ASA.  The following table summarizes compensation expense we recognized in connection with equity-based awards for the periods indicated:
		For the Three Months					For the Six Months
		Ended June 30,					Ended June 30,
		2014			2013		2014		2013
	Equity-classified awards:
	Restricted common unit awards	$	9		$	18.3	$	20.6	$	34.9
	Unit option awards		--			0.2		--		0.6
	Phantom unit awards		13.6			--		19.4		--
	Liability-classified awards		0.2			0.1		0.3		0.3
	Total	$	22.8		$	18.6	$	40.3	$	35.8
	The fair value of equity-classified awards is amortized to earnings over the requisite service or vesting period.  Equity-classified awards are expected to result in the issuance of common units upon vesting.  Compensation expense for liability-classified awards is recognized over the requisite service or vesting period based on the fair value of the award remeasured at each reporting date.  Liability-classified awards are settled in cash upon vesting.
	At June 30, 2014, EPCO's significant long-term incentive plans applicable to us were the Enterprise Products 1998 Long-Term Incentive Plan ("1998 Plan") and the 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) ("2008 Plan").  Up to 7,000,000 of our common units may be issued as awards under the 1998 Plan.  The maximum number of common units available for issuance under the 2008 Plan was 12,500,000 at June 30, 2014.  This amount will automatically increase under the terms of the 2008 Plan by 2,500,000 common units on January 1, 2015 and will continue to automatically increase annually on January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 35,000,000 common units.  After giving effect to awards granted under the 1998 Plan and 2008 Plan through June 30, 2014, a total of 1,340,885 and 6,388,498 additional common units could be issued under these plans, respectively.
	Restricted Common Unit Awards
	Restricted common unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions.  Restricted common unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire.  Restricted common units are included in the number of common units outstanding as presented on our Unaudited Condensed Consolidated Balance Sheets.
	The following table presents information regarding restricted common unit awards for the period indicated:
		Number of			Weighted-
		Units			Average Grant
					Date Fair Value
					per Unit (1)
	Restricted common units at December 31, 2013		3,610,607		$	51.66
	Vested		(1,276,762	)	$	47.81
	Forfeited		(115,250	)	$	52.49
	Restricted common units at June 30, 2014		2,218,595		$	53.84
	(1)   Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued.
	Each recipient of a restricted common unit award is entitled to nonforfeitable cash distributions equal to the product of the number of restricted common units outstanding for the participant and the cash distribution per unit paid by Enterprise to its common unitholders.  These distributions are included in "Cash distributions paid to limited partners" as presented on our Unaudited Condensed Statements of Consolidated Cash Flows.
	The following table presents supplemental information regarding our restricted common unit awards for the periods indicated:
		For the Three Months					For the Six Months
		Ended June 30,					Ended June 30,
		2014			2013		2014		2013
	Cash distributions paid to restricted common unitholders	$	1.6		$	3	$	4.1	$	5.6
	Total intrinsic value of restricted common unit awards that vested during period	$	2.7		$	54	$	84.1	$	106.4
	For the EPCO group of companies, the unrecognized compensation cost associated with restricted common unit awards was an aggregate $47.1 million at June 30, 2014, of which our allocated share of the cost is currently estimated to be $42.2 million.  Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 1.7 years.
	Unit Option Awards
	EPCO's long-term incentive plans provide for the issuance of non-qualified incentive options denominated in the common units of Enterprise Products Partners L.P.  In general, unit option awards have a vesting period of four years from the date of grant and expire at the end of the calendar year following the year of vesting (e.g., an option vesting on May 29, 2013 will expire on December 31, 2014).  However, unit option awards only become exercisable at certain times during the calendar year following the year in which they vest (typically the months of February, May, August and November).

	As of June 30, 2014, all compensation expense related to unit option awards had been recognized.
	Phantom Unit Awards
	Phantom unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions.  Phantom unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire.
	At June 30, 2014, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards.  Compensation expense attributable to these awards is based on the grant date fair value of the award, net of an allowance for estimated forfeitures, amortized over the requisite service or vesting period.  The grant date fair value of a phantom unit award is based on the market price per unit of Enterprise's common units on the date of grant.  These awards were first issued in February 2014.
	The following table presents phantom unit award activity for the period indicated:
		Number of			Weighted-

Forfeited		(32,070	)	$	66.08
Phantom unit awards at June 30, 2014		1,690,075		$	66.11
(1)   Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued.
(2)   The aggregate grant date fair value of phantom unit awards issued during 2014 was $114.9 million based on a grant date market price of our common units ranging from $66.08 to $74.55 per unit. An estimated annual forfeiture rate of 3.4% was applied to these awards.
Our long-term incentive plans provide for the issuance of distribution equivalent rights ("DERs") in connection with phantom unit awards.  A DER entitles the participant to nonforfeitable cash payments equal to the product of the number of phantom unit awards outstanding for the participant and the cash distribution per common unit paid by Enterprise to its common unitholders.  Cash payments made in connection with DERs are charged to partners' equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed.
The following table presents supplemental information regarding our phantom unit awards and DERs for the periods indicated:
	For the Three Months					For the Six Months
	Ended June 30,					Ended June 30,
	2014			2013		2014		2013
Cash payments made in connection with DERs	$	1.2		$	--	$	1.2	$	--
Total intrinsic value of phantom unit awards that vested during period	$	1.2		$	--	$	1.2	$	--
For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $84.2 million at June 30, 2014, of which our allocated share of the cost is currently estimated to be $77.4 million.  Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 2.3 years.

Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]	'
Derivative Instruments, Hedging Activities and Fair Value Measurements	'
	Note 4.  Derivative Instruments, Hedging Activities and Fair Value Measurements
	In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.
	Interest Rate Hedging Activities
	We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  The following table summarizes our portfolio of interest rate swaps at June 30, 2014:
	Hedged Transaction	Number and Type		Notional			Period of	Rate	Accounting
		of Derivatives		Amount			Hedge	Swap	Treatment
		Outstanding
	Senior Notes AA	10 fixed-to-floating swaps		$	750		1/2011 to 2/2016	3.2% to 1.2%	Fair value hedge
	Undesignated swaps	6 floating-to-fixed swaps		$	600		5/2010 to 7/2014	0.2% to 2.0%	Mark-to-market
	In July 2014, six undesignated floating-to-fixed swaps having an aggregate notional amount of $600.0 million, that were outstanding at June 30, 2014, expired.  These swaps were accounted for as mark-to-market instruments with changes in fair value recorded in "Interest expense" on our Unaudited Condensed Statements of Consolidated Operations.
	In connection with the issuance of Senior Notes II and HH in March 2013, we settled 16 forward starting swaps having an aggregate notional amount of $1.0 billion, that were outstanding at December 31, 2012, which resulted in cash losses totaling $168.8 million.  These losses are a component of accumulated other comprehensive loss and are being amortized to earnings (as an increase in interest expense) over the forecasted hedge period of ten years using the effective interest method.
	Commodity Hedging Activities
	The prices of natural gas, NGLs, crude oil, refined products and petrochemical products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts.  The following table summarizes our portfolio of commodity derivative instruments outstanding at June 30, 2014 (volume measures as noted):
		Volume (1)		Accounting
	Derivative Purpose	Current (2)	Long-Term (2)	Treatment
	Derivatives designated as hedging instruments:
	Natural gas processing:
	Forecasted natural gas purchases for plant thermal reduction (Bcf)	2.2	n/a	Cash flow hedge
	Forecasted sales of NGLs (MMBbls) (3)	0.6	n/a	Cash flow hedge
	Octane enhancement:
	Forecasted purchases of NGLs (MMBbls)	0.1	n/a	Cash flow hedge
	Forecasted sales of octane enhancement products (MMBbls)	1.6	n/a	Cash flow hedge
	Natural gas marketing:
	Natural gas storage inventory management activities (Bcf)	3.3	n/a	Fair value hedge
	NGL marketing:
	Forecasted purchases of NGLs and related hydrocarbon products (MMBbls)	6.2	n/a	Cash flow hedge
	Forecasted sales of NGLs and related hydrocarbon products (MMBbls)	7.6	n/a	Cash flow hedge
	Refined products marketing:
	Forecasted purchases of refined products (MMBbls)	0.6	n/a	Cash flow hedge
	Forecasted sales of refined products (MMBbls)	1	n/a	Cash flow hedge
	Refined products inventory management activities (MMBbls)	0.2	n/a	Fair value hedge
	Crude oil marketing:
	Forecasted purchases of crude oil (MMBbls)	3.3	n/a	Cash flow hedge
	Forecasted sales of crude oil (MMBbls)	5	n/a	Cash flow hedge
	Derivatives not designated as hedging instruments:
	Natural gas risk management activities (Bcf) (4,5)	73.1	12.6	Mark-to-market
	Crude oil risk management activities (MMBbls) (5)	13.2	n/a	Mark-to-market
	(1)   Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes.
	(2)   The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is March 2015, August 2014 and October 2016, respectively.
	(3)   Forecasted sales of NGL volumes under natural gas processing exclude 0.6 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements.
	(4)   Current volumes include 37.7 Bcf of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences.
	(5)   Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.
	At June 30, 2014, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging the fair value of commodity products held in inventory, (iii) hedging natural gas processing margins, and (iv) hedging octane enhancement margins.

Fair Value Measurements
Our fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk, in the principal market of the asset or liability at a specified measurement date.  Recognized valuation techniques employ inputs such as contractual prices, quoted market prices or rates, operating costs, discount factors and business growth rates.  These inputs may be either readily observable, corroborated by market data or generally unobservable.  In developing our estimates of fair value, we endeavor to utilize the best information available and apply market-based data to the highest extent possible.  Accordingly, we utilize valuation techniques (such as the market approach) that maximize the use of observable inputs and minimize the use of unobservable inputs.
A three-tier hierarchy has been established that classifies fair value amounts recognized in the financial statements based on the observability of inputs used to estimate such fair values.  The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3).  At each balance sheet reporting date, we categorize our financial assets and liabilities using this hierarchy.
Recurring Fair Value Measurements
The following tables set forth, by level within the fair value hierarchy, the carrying values of our financial assets and liabilities at June 30, 2014 and December 31, 2013.  These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value.  Our assessment of the relative significance of such inputs requires judgment.

(1)   There were $5.0 million and $0.5 million of unrealized losses included in these amounts for the three and six months ended June 30, 2014, respectively.  There were unrealized gains of $0.4 million and $1.3 million included in these amounts for the three and six months ended June 30, 2013, respectively.
(2)   There were no transfers into or out of Level 3 during the three or six months ended June 30, 2014 and 2013.
The following table provides quantitative information about our recurring Level 3 fair value measurements at June 30, 2014:
		Fair Value

		Assets				Liabilities			Techniques	Input
Commodity derivatives – Crude oil		$	4.1			$	1.5		Discounted cash flow	Forward commodity prices	$94.16-$106.21/barrel
We believe forward commodity prices are the most significant unobservable inputs in determining our Level 3 recurring fair value measurements at June 30, 2014.  In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold.  We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures.
Nonrecurring Fair Value Measurements

Other Fair Value Information
The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature.  The estimated total fair value of our fixed-rate debt obligations was $20.35 billion and $18.4 billion at June 30, 2014 and December 31, 2013, respectively.  The aggregate carrying value of these debt obligations was $18.38 billion and $17.36 billion at June 30, 2014 and December 31, 2013, respectively.  These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based.  We do not have any long-term investments in debt or equity securities recorded at fair value.

	(1)   Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; office furniture and equipment; buildings; laboratory and shop equipment and related assets.
	(2)   Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets.
	(3)   Platforms and facilities include offshore platforms and related facilities and other associated assets located in the Gulf of Mexico.
	(4)   Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.
	(5)   Marine vessels include tow boats, barges and related equipment used in our marine transportation business.
	(6)   In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; office furniture and equipment, 3-20 years; buildings, 20-40 years; and laboratory and shop equipment, 5-35 years.

	The following table summarizes our depreciation expense and capitalized interest amounts for the periods indicated:
			For the Three Months								For the Six Months
			Ended June 30,								Ended June 30,

	Capitalized interest (2)			17.7				35.7				36.2				67.3
	(1)   Depreciation expense is a component of "Costs and expenses" as presented on our Unaudited Condensed Statements of Consolidated Operations.
	(2)   We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset's estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.
	In March 2013, we sold the Stratton Ridge-to-Mont Belvieu segment of the Seminole Pipeline, along with a related storage cavern, for cash proceeds of $86.9 million.  As a result, net income for the six months ended June 30, 2013 includes a $52.5 million gain attributable to the sale of these assets.  The Seminole Pipeline remains connected to our Mont Belvieu complex through a newly constructed NGL pipeline that we own.
	In April 2013, we sold certain lubrication oil and specialty chemical distribution assets for cash proceeds of $35.3 million.  As a result, net income for the three and six months ended June 30, 2013 includes a $6.7 million gain from the sale of these assets.
	Asset Retirement Obligations
	Property, plant and equipment at June 30, 2014 and December 31, 2013 includes $32.3 million and $37.4 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset.

	(1)   The total carrying amount of goodwill at June 30, 2014 and December 31, 2013 is net of $1.3 million of accumulated impairment charges. No goodwill impairment charges were recorded during the six months ended June 30, 2014.
	In January 2014, our Appalachia-to-Texas Express ("ATEX") ethane pipeline commenced operations.  In addition to construction of new assets, this project involved repurposing portions of the TE Products Pipeline to accommodate the southbound delivery of ethane produced from the Marcellus and Utica Shales to the U.S. Gulf Coast. The repurposed assets were reclassified from the Petrochemical & Refined Products Services business segment to the NGL Pipelines & Services business segment in January 2014 when the ATEX pipeline commenced operations.  Pipeline assets that continue to be utilized by the TE Products Pipeline in the northbound delivery of refined products and other hydrocarbons from the U.S. Gulf Coast remain in the Petrochemical & Refined Products Services business segment.
	In total, the carrying value of the fixed assets at January 1, 2014 that were transferred from the TE Products Pipeline to the ATEX pipeline was $73.7 million.  Based on the relative fair values of the assets involved, we also transferred $520.0 million of goodwill from the Petrochemical & Refined Products Services business segment to the NGL Pipelines & Services business segment.  The relative fair values of the segment assets were determined based on assumptions regarding the future economic prospects of the ATEX pipeline versus the other assets that would remain in the associated reporting unit.  These assumptions included: (i) discrete financial forecasts for the pipelines and related businesses contained within the reporting unit, which, in turn, relied on management's estimates of future operating margins, throughput volumes and similar factors; (ii) long-term growth rates for cash flows beyond the discrete forecast period; and (iii) appropriate discount rates.  We believe our assumptions are consistent with those that market participants would utilize in estimating the reporting unit's fair value.

	In February 2014, EPO issued $850 million in principal amount of 3.90% senior notes due February 2024 ("Senior Notes JJ") and $1.15 billion in principal amount of 5.10% senior notes due February 2045 ("Senior Notes KK").  Senior Notes JJ were issued at 99.811% of their principal amount and Senior Notes KK were issued at 99.845% of their principal amount.  Proceeds from the issuance of Senior Notes JJ and KK were used to repay debt, including amounts then outstanding under EPO's commercial paper program (which EPO used to repay $500.0 million in principal amount of Senior Notes O that matured in January 2014) and for general company purposes.
	Enterprise Products Partners L.P. has unconditionally guaranteed Senior Notes JJ and KK on an unsecured and unsubordinated basis.  These senior notes rank equal with EPO's existing and future unsecured and unsubordinated indebtedness and are senior to any existing and future subordinated indebtedness of EPO.  These senior notes are subject to make-whole redemption rights and were issued under indentures containing certain covenants, which generally restrict EPO's ability (with certain exceptions) to incur debt secured by liens and engage in sale and leaseback transactions.
	364-Day Credit Agreement Terminated on May 1, 2014
Effective May 1, 2014, EPO elected to terminate its $1.0 billion 364-Day Credit Agreement in advance of the facility's scheduled maturity date of June 18, 2014.  No borrowings were made under this variable-rate revolving credit facility since its inception.
Letters of Credit
At June 30, 2014, EPO had $2.5 million of letters of credit outstanding related to operations at our facilities and motor fuel tax obligations.
Lender Financial Covenants
We were in compliance with the financial covenants of our consolidated debt agreements at June 30, 2014.

Equity and Distributions	'
	Note 10.  Equity and Distributions
	Partners' equity reflects the various classes of limited partner interests (i.e., common units, including restricted common units) that we have outstanding.  The following table summarizes changes in the number of Enterprise's outstanding units since December 31, 2013:
			Common				Restricted				Total
			Units				Common				Common
			(Unrestricted)				Units				Units
	Number of units outstanding at December 31, 2013			932,074,401				3,610,607				935,685,008

	We may issue additional equity or debt securities to assist us in meeting our future liquidity and capital spending requirements.  We have a universal shelf registration statement (the "2013 Shelf") on file with the SEC.  The 2013 Shelf allows Enterprise Products Partners L.P. and EPO (on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively.  EPO utilized the 2013 Shelf to issue $2.0 billion of senior notes in February 2014 (see Note 9).
	We have a registration statement on file with the SEC covering the issuance of up to $1.25 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings.  Pursuant to this "at-the-market" program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers' transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement.  During the six months ended June 30, 2014, we sold 795,167 common units under the "at-the-market" program for aggregate gross proceeds of $58.3 million, resulting in net cash proceeds of $57.7 million.  During the six months ended June 30, 2013, we sold 3,766,557 common units under the program for aggregate gross proceeds of $228.5 million. After taking into account applicable costs, these transactions resulted in net cash proceeds of $226.5 million, of which $214.2 million was received as of June 30, 2013.  After taking into account the aggregate sale price of common units sold under our at-the-market program through June 30, 2014, we have the capacity to issue additional common units under this program up to an aggregate sales price of $1.19 billion.
	We also have registration statements on file with the SEC collectively authorizing the issuance of up to 70,000,000 of our common units in connection with a distribution reinvestment plan (or "DRIP").  We issued 2,445,439 common units under our DRIP during the six months ended June 30, 2014, which generated net cash proceeds of $160.4 million.  During the six months ended June 30, 2013, we issued 2,359,089 common units, which generated net cash proceeds of $129.8 million.  After taking into account the number of common units issued under the DRIP through June 30, 2014, we have the capacity to issue an additional 16,035,439 common units under this plan.
	In January 2014, privately held affiliates of EPCO expressed their willingness to consider purchasing through the DRIP a total of $100 million of our common units during 2014.  During the six months ended June 30, 2014, these EPCO affiliates reinvested $50.0 million, resulting in the issuance of 761,487 common units under our DRIP (this amount being a component of the total common units issued under the DRIP for the six months ended June 30, 2014).  On August 7, 2014, these EPCO affiliates reinvested an additional $25 million through the DRIP.
	In addition to the DRIP, we have registration statements on file with the SEC authorizing the issuance of up to 4,000,000 of our common units in connection with an employee unit purchase plan (or "EUPP").  We issued 74,530 common units under our EUPP during the six months ended June 30, 2014, which generated net cash proceeds of $5.2 million.  During the six months ended June 30, 2013, we issued 81,695 common units, which generated net cash proceeds of $4.8 million.  After taking into account the number of common units issued under the EUPP through June 30, 2014, we may issue an additional 3,638,914 common units under this plan.
	The net cash proceeds we received from the issuance of common units during the six months ended June 30, 2014 were used to temporarily reduce amounts outstanding under EPO's commercial paper program and for general company purposes.
	Two-for-One Split of Limited Partner Units
	On July 15, 2014, we announced that our general partner approved a two-for-one split of our common units.  The common unit split will be accomplished by distributing one additional common unit for each common unit outstanding as of the close of business on August 14, 2014.  See Note 18 for additional information regarding this subsequent event.

	Cash Distributions
	The following table presents Enterprise's declared quarterly cash distribution rates per common unit with respect to the quarter indicated:
			Distribution Per			Record	Payment
			Common Unit			Date	Date
	2013:00:00
	1st Quarter		$	0.67		4/30/13	5/7/13
	2nd Quarter		$	0.68		7/31/13	8/7/13
	2014:00:00
	1st Quarter		$	0.71		4/30/14	5/7/14
2nd Quarter		$	0.72		7/31/14	8/7/14
As noted previously, on July 15, 2014, we announced that our general partner approved a two-for-one common unit split that will be completed on August 21, 2014 (see Note 18).  The common unit split will reduce declared future distributions per common unit (e.g., a $0.72 per unit distribution rate will become a $0.36 per unit distribution rate), but not the total amount of distributions paid since the number of common units outstanding will increase proportionally (i.e., the number of common units outstanding will double).
In November 2010, we completed our merger with Enterprise GP Holdings L.P. (the "Holdings Merger").  In connection with the Holdings Merger, a privately held affiliate of EPCO agreed to temporarily waive the regular quarterly cash distributions it would otherwise receive from us with respect to a certain number of our common units it owns (the "Designated Units"). Distributions paid during 2014 exclude 22,560,000 Designated Units.  Distributions to be paid, if any, during 2015 will exclude 17,690,000 Designated Units.

Business Segments [Abstract]	'
Business Segments	'
	Note 11.  Business Segments
	We have five reportable business segments: (i) NGL Pipelines & Services; (ii) Onshore Natural Gas Pipelines & Services; (iii) Onshore Crude Oil Pipelines & Services; (iv) Offshore Pipelines & Services; and (v) Petrochemical & Refined Products Services.  Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.
	We evaluate segment performance based on the non-GAAP financial measure of gross operating margin.  Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations.  This measure forms the basis of our internal financial reporting and is used by our executive management in deciding how to allocate capital resources among business segments.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results.  The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.
	In total, gross operating margin represents operating income exclusive of (1) depreciation, amortization and accretion expenses, (2) impairment charges, (3) gains and losses attributable to asset sales and insurance recoveries and (4) general and administrative costs.  Gross operating margin includes equity in income of unconsolidated affiliates and non-refundable deferred transportation revenues relating to the make-up rights of committed shippers associated with certain pipelines.  Gross operating margin by segment is calculated by subtracting segment operating costs and expenses (net of the adjustments noted above) from segment revenues, with both segment totals before the elimination of intercompany transactions.  In accordance with GAAP, intercompany accounts and transactions are eliminated in consolidation.  Gross operating margin is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests.
	Segment revenues include intersegment and intrasegment transactions, which are generally based on transactions made at market-based rates.  Our consolidated revenues reflect the elimination of intercompany transactions.  Substantially all of our consolidated revenues are earned in the U.S. and derived from a wide customer base.
	Segment assets consist of property, plant and equipment, investments in unconsolidated affiliates, intangible assets and goodwill.  The carrying values of such amounts are assigned to each segment based on each asset's or investment's principal operations and contribution to the gross operating margin of that particular segment.  Since construction-in-progress amounts (a component of property, plant and equipment) generally do not contribute to segment gross operating margin, such amounts are excluded from segment asset totals until the underlying assets are placed in service.  Intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate.  Substantially all of our plants, pipelines and other fixed assets are located in the U.S.
	The following table presents our measurement of non-GAAP total segment gross operating margin for the periods indicated:

(1)   Represents cost of operating our plants, pipelines and other fixed assets, excluding depreciation, amortization and accretion charges.
Period-to-period fluctuations in our product sales revenues and related cost of sales amounts are explained in part by changes in energy commodity prices.  In general, lower energy commodity prices result in a decrease in our revenues attributable to product sales; however, these lower commodity prices also decrease the associated cost of sales as purchase costs decline.  The same correlation would be true in the case of higher energy commodity sales prices and purchase costs.

	Relationship with EPCO and Affiliates
	We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies.  At June 30, 2014, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts, the beneficiaries of which include the estate of Dan L. Duncan) beneficially owned the following limited partner interests in us:

		Total Units

	341,641,866	36.40%
	We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations.  During the six months ended June 30, 2014 and 2013, we paid EPCO and its privately held affiliates cash distributions totaling $431.8 million and $397.5 million, respectively.
	From time-to-time, EPCO and its privately held affiliates elect to reinvest a portion of the cash distributions they receive from us into the purchase of additional common units under our DRIP.  See Note 10 for information regarding reinvestments made during 2014.
	We have no employees.  All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to the ASA or by other service providers.

	(1)    Each phantom unit award includes a DER, which entitles the recipient to receive cash payments equal to the product of the number of phantom unit awards and the cash distribution per unit paid to Enterprise's common unitholders. Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. Phantom unit awards were first issued in February 2014.
	(2)    The Class B units automatically converted into an equal number of distribution-bearing common units in August 2013.

Commitments and Contingencies [Abstract]	'
Commitments and Contingencies	'
	Note 14.  Commitments and Contingencies
	Litigation
	As part of our normal business activities, we may be named as defendants in legal proceedings, including those arising from regulatory and environmental matters.  Although we are insured against various 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 fully indemnify us against losses arising from future legal proceedings.  We will vigorously defend the partnership in litigation matters.
	Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the possible need for accounting recognition and disclosure of these contingencies.  We accrue an undiscounted liability for those contingencies where the loss is probable and the amount can be reasonably estimated.  If a range of probable loss amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum amount in the range is accrued.
	We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote.  For contingencies where an unfavorable outcome is reasonably possible and the impact would be material to our consolidated financial statements, we disclose the nature of the contingency and, where feasible, an estimate of the possible loss or range of loss.  Based on a consideration of all relevant known facts and circumstances, we do not believe that the ultimate outcome of any currently pending litigation directed against us will have a material impact on our consolidated financial statements either individually at the claim level or in the aggregate.
	At June 30, 2014 and December 31, 2013, our accruals for litigation contingencies were $2.3 million and $3.7 million, respectively, and were recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of "Other current liabilities."  Our evaluation of litigation contingencies is based on the facts and circumstances of each case and predicting the outcome of these matters involves uncertainties.  In the event the assumptions we use to evaluate these matters change in future periods or new information becomes available, we may be required to record additional accruals.  In an effort to mitigate expenses associated with litigation, we may settle legal proceedings out of court.
	ETP Matter.  In connection with a proposed pipeline project, we and Energy Transfer Partners, L.P. ("ETP") signed a non-binding letter of intent in April 2011 that disclaimed any partnership or joint venture related to such project absent executed definitive documents and board approvals of the respective companies.  Definitive agreements were never executed and board approval was never obtained for the potential pipeline project.  In August 2011, the proposed pipeline project was cancelled due to a lack of customer support.
	In September 2011, ETP filed suit against us and a third party in connection with the cancelled project alleging, among other things, that we and ETP had formed a "partnership."  The case was tried in the District Court of Dallas County, Texas, 298th Judicial District.  While we firmly believe, and argued during our defense, that no agreement was ever executed forming a legal joint venture or partnership between the parties, the jury found that the actions of the two companies, nevertheless, constituted a legal partnership.  As a result, the jury found that ETP was wrongfully excluded from a subsequent pipeline project involving a third party, and awarded ETP $319.4 million in actual damages on March 4, 2014.  On July 29, 2014, the court entered judgment against us in an aggregate amount of $535.8 million, which includes (i) $319.4 million as the amount of actual damages awarded by the jury, (ii) an additional $150.0 million in disgorgement for the alleged benefit we received due to a breach of fiduciary duties by us against ETP and (iii) prejudgment interest in the amount of $66.4 million.  The court also awarded post-judgment interest on such aggregate amount, to accrue at a rate of 5% per annum, compounded annually.
	We do not believe that the verdict or the judgment entered against us is supported by the evidence or the law and intend to vigorously oppose the judgment through the appeals process.  As of June 30, 2014, we have not recorded a provision for this matter as management believes payment of damages in this case is not probable.
	Contractual Obligations
	Scheduled Maturities of Debt.  With the exception of routine fluctuations in the balance of our revolving credit facility and commercial paper notes, the issuance of senior notes in February 2014 and the scheduled repayment of maturing debt obligations, there have been no significant changes in our consolidated debt obligations since those reported in our 2013 Form 10-K.  See Note 9 for additional information regarding our consolidated debt obligations.
	Operating Lease Obligations.  Consolidated lease and rental expense was $22.5 million and $23.3 million during the second quarters of 2014 and 2013, respectively.  For the six months ended June 30, 2014 and 2013, consolidated lease and rental expense was $45.7 million and $45.3 million, respectively.
	During the second quarter of 2014, we entered into a long-term lease in connection with our plans to construct an ethane export terminal on the Houston Ship Channel.  In addition, we entered into long-term railcar leases in connection with our other operations.  On a combined basis, these agreements increased our estimated long-term operating lease obligations by approximately $34 million over the next five years and $144 million overall.  Apart from these new agreements, there have been no other material changes in our operating lease commitments since those reported in our 2013 Form 10-K.
	Purchase Obligations.  There have been no material changes in our consolidated purchase obligations since those reported in our 2013 Form 10-K.

Insurance Matters [Abstract]	'
Significant Risks and Uncertainties	'
	Note 15.  Insurance Matters
	We participate as a named insured in EPCO's insurance program, which provides us with property damage, business interruption and other insurance coverage, the scope and amounts of which we believe are customary and prudent for the nature and extent of our operations.  While we believe EPCO maintains adequate insurance coverage on our behalf, insurance may not fully cover every type of damage, interruption or other loss that might occur.
	We elected to forego windstorm coverage for our Gulf of Mexico offshore assets during the 2014 Atlantic hurricane season, which extends from June 1 through November 30.  The combination of increasingly high deductibles and proposed premiums resulted in such coverage being uneconomic to us.  Although EPCO's coverage does not provide any windstorm coverage for our offshore assets during the annual policy period that began on June 1, 2014, producers affiliated with our Independence Hub and Marco Polo platforms will continue to provide certain levels of physical damage windstorm coverage for each of these key offshore assets.
	West Storage Claims
	In February 2011, we experienced an NGL release and fire at the West Storage location of our Mont Belvieu, Texas underground storage facility.  We collected $95.0 million and $8.8 million of nonrefundable cash insurance proceeds attributable to this incident during the six months ended June 30, 2014 and 2013, respectively.  The payments we received during the first quarter of 2014 represent the final installments on this property damage claim.
	Operating income for the six months ended June 30, 2014 and 2013 includes $95.0 million and $8.8 million, respectively, of gains related to these insurance recoveries.  To the extent that we received nonrefundable cash insurance proceeds related to this incident, we recorded gains equal to such proceeds as a reduction in operating costs and expenses.

	Two-for-One Split of Limited Partner Units
	On July 15, 2014, we announced that our general partner approved a two-for-one split of our common units.  The common unit split will be accomplished by distributing one additional common unit for each common unit outstanding.  The additional common units will be distributed on August 21, 2014 to holders of record as of the close of business on August 14, 2014.
	All per unit amounts and number of units outstanding in these Unaudited Condensed Consolidated Financial Statements and Notes thereto are presented on a pre-split basis.  As a result of the common unit split, all historical per unit data and number of units outstanding presented in future financial statements will be retroactively adjusted.
	The following table presents pro forma earnings per unit (giving retroactive effect solely to the unit split) for the periods indicated:

General Accounting Matters [Abstract]	'
Contingencies	'
	Contingencies
	Certain conditions may exist as of the date our consolidated financial statements are issued, which may result in a loss to us but which will only be resolved when one or more future events occur or fail to occur.  Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the need for accounting recognition or disclosure of these contingencies, and such assessment inherently involves an exercise in judgment.  In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, our management and legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.
	We accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated.  If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued.  We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when it is believed to be only reasonably possible or remote.
	For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, we disclose the nature of the contingency and, if feasible, an estimate of the possible loss or range of loss.
	Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed.  See Note 14 for additional information regarding our contingencies.
Derivative Instruments	'
	Derivative Instruments
	We use derivative instruments such as futures, swaps, options, forward contracts and other arrangements to manage price risks associated with inventories, firm commitments, interest rates, foreign currencies and certain anticipated future commodity transactions.  To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted.  We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a monthly basis thereafter.  Forecasted transactions are evaluated for the probability of occurrence and are periodically back-tested once the forecasted period has passed to determine whether similarly forecasted transactions are probable of occurring in the future.
	For certain physical forward commodity derivative contracts, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such contracts are not recognized in income.  As a result, the revenues and expenses associated with such physical transactions are recognized during the period when volumes are physically delivered or received.  Physical forward commodity contracts subject to this exception are evaluated for the probability of future delivery and are periodically back-tested once the forecasted period has passed to determine whether similar forward contracts are probable of physical delivery in the future.  See Note 4 for additional information regarding our derivative instruments.
Estimates	'
	Estimates
	Preparing our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates that affect amounts presented in the financial statements.  Our most significant estimates relate to (i) the useful lives and depreciation/amortization methods used for fixed and identifiable intangible assets; (ii) measurement of fair value and projections used in impairment testing of fixed and intangible assets (including goodwill); (iii) contingencies; and (iv) revenue and expense accruals.
	Actual results could differ materially from our estimates.  On an ongoing basis, we review our estimates based on currently available information.  Any changes in the facts and circumstances underlying our estimates may require us to update such estimates, which could have a material impact on our consolidated financial statements.
Restricted Cash	'
	Restricted Cash
	Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, crude oil, refined products and NGLs.  Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or deposit requirements change.  At June 30, 2014 and December 31, 2013, our restricted cash amounts were $56.7 million and $65.6 million, respectively.  See Note 4 for information regarding our derivative instruments and hedging activities.

Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]	'
Hedging Instruments Under the FASB's Derivative and Hedging Guidance	'
	We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  The following table summarizes our portfolio of interest rate swaps at June 30, 2014:
	Hedged Transaction	Number and Type		Notional			Period of	Rate	Accounting
		of Derivatives		Amount			Hedge	Swap	Treatment
		Outstanding
	Senior Notes AA	10 fixed-to-floating swaps		$	750		1/2011 to 2/2016	3.2% to 1.2%	Fair value hedge
	Undesignated swaps	6 floating-to-fixed swaps		$	600		5/2010 to 7/2014	0.2% to 2.0%	Mark-to-market
	The prices of natural gas, NGLs, crude oil, refined products and petrochemical products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts.  The following table summarizes our portfolio of commodity derivative instruments outstanding at June 30, 2014 (volume measures as noted):
		Volume (1)		Accounting

	(1)   Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes.
	(2)   The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is March 2015, August 2014 and October 2016, respectively.
	(3)   Forecasted sales of NGL volumes under natural gas processing exclude 0.6 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements.
	(4)   Current volumes include 37.7 Bcf of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences.

	(1)    Each phantom unit award includes a DER, which entitles the recipient to receive cash payments equal to the product of the number of phantom unit awards and the cash distribution per unit paid to Enterprise's common unitholders. Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. Phantom unit awards were first issued in February 2014.
	(2)    The Class B units automatically converted into an equal number of distribution-bearing common units in August 2013.

[1]	Depreciation expense is a component of "Costs and expenses" as presented on our Unaudited Condensed Statements of Consolidated Operations.
[2]	We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset's estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.
[3]	Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; office furniture and equipment; buildings; laboratory and shop equipment and related assets.
[4]	In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; office furniture and equipment, 3-20 years; buildings, 20-40 years; and laboratory and shop equipment, 5-35 years.
[5]	Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets.
[6]	In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years.
[7]	Platforms and facilities include offshore platforms and related facilities and other associated assets located in the Gulf of Mexico.
[8]	Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.
[9]	Marine vessels include tow boats, barges and related equipment used in our marine transportation business.

[1]	Each phantom unit award includes a DER, which entitles the recipient to receive cash payments equal to the product of the number of phantom unit awards and the cash distribution per unit paid to Enterprise's common unitholders. Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. Phantom unit awards were first issued in February 2014.
[2]	The Class B units automatically converted into an equal number of distribution-bearing common units in August 2013.
