Exhibit 10.3




FORM OF STORAGE LEASE

(North Propane-Propylene Splitters)




     This is a Storage Lease (the “Lease”) between MONT BELVIEU CAVERNS, LLC with an address
at P.O. Box 4324, Houston, Texas 77210-4324 (“Lessor”) and ENTERPRISE PRODUCTS OPERATING L.P.,
(“Lessee”), with an address at P.O. Box 4324, Houston, Texas 77210-4324.



1. Term; Quantity; Product.



For an initial term commencing January 1, 2007 and ending December 31, 2016 (the “Initial Term”),
Lessor leases to Lessee storage space of up to *** barrels of refinery grade propylene (“RGP”) and
*** barrels of polymer grade propylene (“PGP”) (collectively referred to as “Product” in this
Lease) at Lessor’s underground storage wells, located near Interstate 10 and State Highway 146 at
Mont Belvieu, Texas, subject to the terms, provisions, and conditions contained herein. For
purposes of this Lease, a “barrel” of Product is equal to 42 U.S. gallons of equivalent liquid
volume at 60° Fahrenheit.



Lessee’s RGP is presently stored in well *** and Lessee’s PGP is presently stored in well ***.
Each well shall be dedicated for Lessee’s sole use. Lessor reserves the right to designate from
time to time which well will be used for the storage of Lessee’s Product; provided, however, to the
best of Lessor’s ability such well shall provide as a minimum, the same amount of storage capacity
and flow capabilities as the well being replaced, unless otherwise mutually agreed to by the
parties. Each such designated well shall then be dedicated for Lessee’s sole use. If it should
become necessary for Lessor to move Lessee’s Product to an alternate well, then Lessor shall
minimize any disruptions and shall pay for all costs and expenses associated with such move.



Notwithstanding anything to the contrary in this Lease, once every five (5) years (unless otherwise
required more often under applicable law, rule, or regulation), Lessor may designate a period of
time as it or its contractors may reasonably require to perform a mechanical integrity test (“MIT”)
during which Lessor shall have the opportunity to inspect the wells, and to conduct any other
operations as may be required by applicable law, rule, or regulation. Accordingly, Lessee shall
cause all of its Product to be removed from the well at issue prior to the first day of the MIT.
Lessor shall make a reasonable effort to provide Lessee with as much advance notice as possible of
the upcoming MIT and the need to empty the subject well, and to coordinate with Lessee (or Lessee’s
designated representative) the scheduling of such MIT. Lessor will pay for the costs associated
with the MIT. If requested by Lessee, Lessor shall make reasonable efforts, at Lessee’s sole cost,
to make alternate storage for Product available to Lessee at the same charges as then being paid to
Lessor by its olefin storage customers; provided, however, under no
circumstances will Lessor be required to make such alternate storage available unless in
Lessor’s sole opinion such alternate storage will not present any hardship on Lessor. Except as



Storage Lease (Enterprise North Propane-Propylene Splitters)




 









 







required by applicable law, rule, or regulation, Lessee shall not be required to lease alternate
storage for a period exceeding the MIT.



Each twelve (12) month period between January 1 and the following December 31 shall be referred to
herein as a “Lease Year”. This Lease shall continue from year to year following the expiration of
the Initial Term, unless either party terminates this Lease by giving written notice to the other
party at least ninety (90) days prior to the beginning of any ensuing Lease Year.




2. Lessor’s Facilities.



Lessor operates storage wells in which various types of products are stored other than the types of
Product covered by this Lease. Lessor’s storage wells are connected to centrally located pipeline
header facilities operated by Lessor on its property in the vicinity of said storage wells. All
Product delivered by Lessee into or by Lessor out of storage must be delivered by pipeline to such
header facilities, and all such deliveries shall be deemed a delivery into or out of storage for
the purposes of computing all applicable charges under this Lease. As between Lessor and Lessee,
control of Lessor’s facilities will rest exclusively with Lessor.




3. Product Specifications.



Each Product delivered by Lessee into storage or by Lessor from storage must meet the respective
specifications set out in Exhibit “A” attached hereto and made a part hereof. Lessor reserves the
right to modify, add to, or revise such specifications at any time and from time-to time upon
giving not less than thirty (30) days prior written notice.




4. Product Deliveries and Receipts.



It shall be Lessee’s responsibility to make all arrangements necessary to deliver Product for
storage and to receive Product from storage at Lessor’s header facilities, and to pay any charges
imposed by any party for the collection, transfer, and injection of Lessee’s Product to such header
facilities for delivery into storage or from such header facilities for delivery out of storage
under this Lease. The flow rates into and out of storage are subject to Lessor’s scheduling and
operational restrictions.




5. Delivery Restrictions; Allocation.



If Lessor’s scheduling or operational restrictions will not permit all of the parties (including
Lessor) storing any types of products in any of Lessor’s storage wells to deliver or receive the
volumes of Product requested, then Lessor may allocate among such parties Lessor’s available flow
rates in a fair and equitable manner as determined by Lessor.




6. Commingling; Sampling.



Lessor shall not commingle Lessee’s Product with Product of other parties and will redeliver to
Lessee the identical Product received from Lessee. Lessor shall have the right to sample all



Storage Lease (Enterprise North Propane-Propylene Splitters)





2









 








Product to be delivered for storage and may refuse to accept delivery of any Product if the Product
does not meet the required specifications or, if in Lessor’s opinion, satisfactory control of
Product specifications will not be maintained during delivery. At Lessor’s request, Lessee shall
provide Lessor access to the Product to be delivered for the purpose of sampling and provide Lessor
representative samples of such Product.




7. Product Measurement.



Measurement of Product into and out of storage shall be made in accordance with the procedures and
methods set out in Exhibit “B”. All Product gains and losses incurred while the product is under
Lessor’s control shall be for the account of Lessee except as noted in Section 13. Lessor
guarantees to return to Lessee in accordance with the provisions of this paragraph 7 all Product
measured into storage. Lessor shall submit to Lessee monthly stock reports supported with
appropriate receiving and shipping information showing movements of Product into and out of storage
and the amount of Product remaining in storage.




(a) Carbon Dioxide.


Lessee will not be credited for any volume of carbon dioxide held in storage for Lessee by Lessor.




(b) Percentages.


Any references to percentages herein shall mean liquid volume percent.




8. Title; Risk of Loss.



Title to Lessee’s Product shall remain at all times in Lessee. Notwithstanding the return
guarantee set out in paragraph 7 above, Lessor shall be responsible for the loss of or damage to
such Product only when and to the extent such loss or damage is caused by the negligence of Lessor,
its employees and agents.




9. Storage Fees.



Lessee agrees to pay Lessor for the storage, handling, and services of Lessor an annual rental as
set forth in the attached Schedule 1. All minimum rentals are payable in full regardless of
whether or not Lessee actually uses the amount of storage made available hereunder. All of
Lessee’s Product must be removed from storage no later than the last day of the term of this Lease,
subject to the payment of accrued rental and other charges and the other terms, provisions, and
conditions of this Lease. The rate for storage of any Product remaining in storage past the last
day of the term of this Lease shall be *** per barrel per month or any portion thereof,
payable in advance on the first day of each month in the same manner and at the same place as set
forth in Section 11.

10. Taxes.



Lessee shall pay all taxes, if any, levied or assessed on the Product stored hereunder. In the
event it becomes necessary for Lessor to pay any such tax, Lessee shall immediately reimburse
Lessor for such amount upon receipt of notice of payment.




11. Payment Terms.



The total minimum annual rental for storage is payable in equal monthly installments during the
term hereof, each of which installments is due and payable in advance by Lessee at Lessor’s address
set forth on the face of each invoice on or before the first day of each month.




12. Warehouseman’s Lien.



Lessor shall have a lien on all Product of Lessee stored hereunder to cover any accrued and unpaid
amounts payable hereunder and may withhold delivery of any such Product until such accrued and
unpaid amounts are paid. If any such amounts remain unpaid for more than thirty (30) days after
they accrue, Lessor may sell said Product at a public auction at the offices of Lessor in Houston,
Harris County, Texas, on any day not a legal holiday and not less than forty-eight (48) hours after
publication of notice in a daily newspaper of general circulation published in Baytown, Texas, said
notice giving the time and place of the sale and the quantity and Product to be sold. Lessor may
be a bidder and a purchaser at such sale. From the proceeds of such sale, Lessor may pay itself
all charges lawfully accruing and all expenses of such sale, and the net balance may be held for
whomsoever may be lawfully entitled thereto.




13. Product Losses.



Product is not insured by Lessor against loss or damage however caused, and any insurance thereon
must be provided and paid for by Lessee. Lessor’s liability, if any, for loss or damages to the
stored Product shall be limited to the market value of Product which shall be equal to the highest
USGC contract reference price for the applicable Product as published in the last issue of the
month in which the Product was delivered of Chemical Marketing Associates Inc.’s Monomers Market
Report, or at Lessor’s option, replacement of such lost or damaged Product in kind.




14. Force Majeure.



Lessor shall not be responsible to Lessee for any loss of Lessee’s Product, for any loss to Lessee
resulting from delays in returning Lessee’s Product when requested, or for failure of Lessor to
perform its obligations hereunder, due, directly or indirectly, to acts of God or other causes
beyond the reasonable control of Lessor including, without limitation, storm; earthquake;
accidents; acts of the public enemy; emergency or unplanned scheduling and
operational restrictions; rebellion; insurrections; sabotage; invasion; epidemic; strikes; lockouts
or other industrial disturbances; war; riot; hurricane; fire; flood; explosion; compliance with
acts, rules, regulations, or orders of federal, state, or local government,

any agency thereof or
other authority having or purporting to have jurisdiction; mechanical failures or similar causes
not due to Lessor’s fault or negligence. The term of this Lease shall not be extended by the
duration of any force majeure, nor shall Lessee be excused from making any payment due under this
Lease. When claiming force majeure, Lessor shall notify Lessee immediately by telephone, and
confirm same in writing, giving reasonable detail regarding the type of force majeure and its
estimated duration. The settlement of differences with workers shall be entirely within the
Lessor’s discretion.




15. Indemnity.



REGARDLESS OF THE LEGAL THEORY OR THEORIES ALLEGED INCLUDING, WITHOUT LIMITATION, THE NEGLIGENCE
(WHETHER SOLE, JOINT, OR CONCURRENT) OF ANY THIRD PARTY, LESSEE HEREBY AGREES TO INDEMNIFY, DEFEND,
AND SAVE HARMLESS LESSOR, ITS PARENT COMPANY, PARTNERS (GENERAL OR LIMITED), MEMBERS, SUBSIDIARIES,
AFFILIATES, SUCCESSORS, AND ASSIGNS, INCLUDING ANY OFFICER, DIRECTOR, EMPLOYEE, OR AGENT OF ANY
SUCH ENTITY (HEREINAFTER COLLECTIVELY CALLED “INDEMNITEE”) FROM AND AGAINST ANY CLAIM, DEMAND,
CAUSE OF ACTION, DAMAGE, FINE, PENALTY, LOSS, JUDGMENT, OR EXPENSE OF ANY KIND OF ANY PARTY
(HEREINAFTER COLLECTIVELY CALLED “LIABILITY”), INCLUDING ANY EXPENSES OF LITIGATION, COURT COSTS,
AND REASONABLE ATTORNEY’S FEES, RESULTING FROM, ARISING OUT OF, OR CAUSED BY THE DELIVERY OF ANY
PRODUCT BY LESSEE OR LESSEE’S AGENT, CONTRACTOR, OR CARRIER WHICH IS CONTAMINATED OR OTHERWISE
FAILS TO MEET THE SPECIFICATIONS SET FORTH HEREIN, EXCEPT TO THE EXTENT SUCH LIABILITY IS DIRECTLY
CAUSED BY THE NEGLIGENCE OR WILLFUL MISCONDUCT OF AN INDEMNITEE.




16. Claims; Limitations.




Notice of claims by Lessee for any liability, loss, damage, or expense arising out of this Lease
must be made to Lessor in writing within ninety-one (91) days after the same shall have accrued.
Such claims, fully amplified, must be filed with Lessor within said ninety-one (91) days and unless
so made and filed, Lessor shall be wholly released and discharged therefrom and shall not be liable
therefor in any court of justice. No suit at law or in equity shall be maintained upon any claim
unless instituted within two (2) years and one (1) day after the cause of action accrued.



In no event shall Lessor be liable to Lessee for any prospective or speculative profits, or
special, indirect, incidental, exemplary, punitive, or consequential damages, whether based upon
contract, tort, strict liability, or negligence, or in any other manner arising out of this Lease,
and Lessee hereby releases Lessor from any claim therefor.

party specifying the nature of the breach; (b) becomes insolvent; or (c) files or has filed against
it a petition in bankruptcy, for reorganization, or for appointment of a receiver or trustee. In
the event of default, the non-defaulting party may terminate this Lease upon notice to the

SCHEDULE 1

STORAGE LEASE

(NORTH PROPANE-PROPYLENE SPLITTERS)




STORAGE FEES.




(A) For the first Lease Year, Lessee shall pay Lessor annual rent at the rate of *** (the “Base
Storage Rental Rate”) for the volume leased under this Lease.



Commencing with the first day of the second Lease Year, and on the first day of each subsequent
Lease Year, the annual rent shall be adjusted as follows: one-half of the Base Storage Rental Rate
shall remain fixed, and one-half shall be revised annually based on a seasonally adjusted implicit
price deflator in order to determine a new rental rate known as the “Adjusted Rental Rate.” The
Adjusted Rental Rate shall be determined in accordance with the following formula:



*** + [*** X Annual Index / Base Index] = Adjusted Rental Rate





	 	Where:	 	“Base Index” is the final seasonally adjusted implicit price deflator figure for the
calendar year 2005 under the Gross Domestic Product column of the “Implicit Price
Deflators for Gross Domestic Product” table (2000=100); and
	 
	 	 	 	“Annual Index” is the final seasonally adjusted implicit price deflator
figure for the calendar year ending immediately before the Lease Year for
which the adjustment is being determined, said figure being in the same
column, table and survey as the Base Index.





The Adjusted Rental Rate shall be rounded off to the fourth decimal place and shall become
effective on the first day of each Lease Year. In no event will the Adjusted Rental Rate ever be
less than the Base Storage Rental Rate.



For example, in calculating the Adjusted Rental Rate, which shall apply under this Lease, assume in
the second Lease Year the Base Index is 113.2, and the Annual Index is 115.2. Under these facts
the Adjusted Rental Rate would be as follows:


*** + [*** X 115.2/113.2] =

*** + [*** X 1.0177] =

*** + *** = ***




The Adjusted Rental Rate of *** would become effective on the first day of the second Lease Year
and would continue until the last day of the second Lease Year, with a new Adjusted Rental Rate to
apply starting on the first day of the third Lease Year, and so on.



Storage Lease (Enterprise North Propane-Propylene Splitters)



 









 





The “Implicit Price Deflators for Gross Domestic Product” are available in the Survey of Current
Business as published monthly by the Bureau of Economic Analysis of the U.S. Department of
Commerce. Subscriptions to the Survey of Current Business are maintained by the Government
Printing Office, an agency of the U.S. Congress. If said Survey fails to publish a necessary price
deflator figure or ceases to be published, any replacement index published by or on behalf of the
United States government shall be substituted, and if there is no such substitute index, the
parties shall promptly agree on a replacement survey or index or, if they cannot agree, either
party shall be entitled to submit the matter of a replacement index to arbitration under the
commercial arbitration rules of the American Arbitration Association.

Storage Lease (Enterprise North Propane-Propylene Splitters)



 









 






	 	a ball or piston-type or small volume prover in accordance with the API MPMS, Chapter 4,
and Chapter 12, Section 2. The prover will be additionally equipped with a densitometer
installed and proved in accordance with the API MPMS, Chapter 14, Section 6. The meter
proving shall be an Inferred Mass Proving in accordance with API MPMS, Chapter 5,
Section 6.9.1.7.2.






	C.	 	Meter proving frequency shall be in accordance with Section 2.3.C below. The meter shall be
proven immediately prior to and after any meter maintenance is performed.





Section 1.3 Densitometers.




	A.	 	Densitometers with frequency output shall be installed and proved in accordance with the
API MPMS, Chapter 14, Section 6. The frequency output may be driven directly into a
flow computer capable of internally converting frequency to corrected flowing density in
gm/cc, or to a separate frequency converter and into the flow computer as a 4-20 ma signal.
Proving is to be by entrapping a sample of the flowing stream at system conditions in a
double-walled high-pressure vessel known as a pycnometer. The connections for the pycnometer
shall be installed in the same manner as those of the densitometer. Thermowells shall be
installed to allow monitoring of the inlet and outlet temperatures. Accuracy of the
densitometer shall be verified at the time of the meter proving or when accuracy is in
question. The accuracy of the densitometer shall be within +/- 0.001 gm/cc over its entire
range and repeatable to +/- 0.0005 gm/cc.






	B.	 	For chemical grade propylene measurement utilizing a turbine meter, a calculated density may
be used in lieu of a densitometer by using the API MPMS, Chapter 11.3.3.2 method for
pure propylene and correcting it for 92 to 96 percent purity by applying a correction factor
of 0.9987 to the prover mass volume at each proving.





Section 1.4 Temperature and Pressure Transmitters. Temperature and pressure transmitters
shall be verified at the time of the meter proving using a certified thermometer and reference gage
respectively to ensure current readings are within +/-0.2 °F and +/- 1.0 psi. A calibration shall
be performed every 6 months. All verification and calibration data shall be supplied to the
customer. Accuracy of these transmitters shall be +/- 0.05 % of scale.



Section 1.5 Flow Computers. Flow computers shall be capable of accepting turbine pulses
from a turbine meter transmitter or mass pulses from a Coriolis meter transmitter and signals from
the pressure, temperature and density transmitters. The computer shall convert, as required, and
totalize these signals into gross volume, mass, and net volume. For net volume determinations, the
computer shall utilize the latest ASTM, API and GPA tables for temperature, pressure and specific
gravity corrections that are applicable to the product being measured. The weight of water shall be
as provided in the latest version of GPA 2145.



Section 1.6 Composite Sampling Systems. Composite sampling systems shall be installed and
operated in accordance with GPA Standard 2174. The composite sampler shall be operated

ACCOUNTING AND MEASUREMENT PROCEDURES




Section 2.1 Custody Transfer Tickets.




	A.	 	EPOLP shall furnish to the customer daily (0700 to 0700) custody transfer tickets unless
otherwise provided for by separate agreement, for products measured on a volumetric basis.
The ticket shall identify the product and state the net volume in barrels of product measured.






	B.	 	For streams that are measured on a mass basis, custody transfer tickets shall be furnished
stating the total mass measured in pounds. Total pounds mass shall then be converted to pounds
of each component (if required) based on its weight fraction of the analysis of the product
removed from the composite sampler for the same time period in which the mass was totalized.
The component pounds shall then be converted to equivalent gallons of each component (if
required) utilizing the calculation procedure outlined in GPA Standard 8173. The component
density in a vacuum shall be in accordance to GPA Standard 2145. Component gallons shall be
further reduced to barrels. Unless otherwise provided for by separate agreement, custody
transfer tickets for mass-measured products shall be generated on a weekly or batch basis. An
unfinished batch shall be closed out at 0700 hours on the first day of the calendar month,
unless otherwise provided for by separate agreement.





Section 2.2 Measurement Basis.



A. Mass Measurement.




	 	1.	 	Inferred mass measurement shall be accomplished utilizing a flow-proportional composite
sampler, turbine meter, densitometer and flow computer to convert gross volumetrically
measured barrels using density in gm/cc at flowing conditions to total pounds mass
according to the following formula:
	 
	 	 	 	TotalPounds = GrossBBLS x MeterFactor x FlowingDensity(gm/cc) x 350.506987






	 	350.506987 is a conversion factor to convert density in gm/cc to pounds /bbl.






	 	 	 	For polymer grade propylene the composite sampler and densitometer are not required.






	2.	 	Direct mass measurement shall be accomplished by utilizing a flow-proportional
composite sampler, a Coriolis meter, Coriolis transmitter, and a flow computer to convert
mass pulses from the Coriolis transmitter into pounds. Measured pounds mass is calculated
according to the following formula:





MeasuredMass = MeterPulses x MeterFactor

               KFactor




Storage Lease (Enterprise North Propane-Propylene Splitters)



 









 






	 	 	For polymer grade propylene the composite sampler is not required.






	B. 	Volumetric Measurement.






	 	1.	 	Volumetric measurement shall be accomplished utilizing a flow computer, turbine
meter, and temperature and pressure transmitters. A “fixed” specific gravity at 60
oF and vapor pressure at 100 oF may be entered into the flow
computer in the case of “purity” products, if agreed by both parties. Temperature and
pressure shall be referenced to the proper API, ASTM and GPA Tables to calculate and
totalize net barrels. An optional densitometer and flow-proportional composite sampler
may be installed. If a densitometer is installed, the flow computer shall convert the
density signal at flowing conditions in gm/cc to specific gravity at 60 oF
and use GPA TP-15 to determine EVP (Equilibrium Vapor Pressure).
	 
	 	2.	 	On the basis of laboratory analysis, components of mixed streams may be
determined by multiplying the totalized net volume by the liquid volume percent of each
component, if so stipulated by contract.






	 	 	The following shall be utilized by the flow computer to reduce gross barrels to net barrels.
	 
	 	 	For Temperature Reduction. API/ASTM/GPA Technical Publication TP-25 Table 24E shall
be used when measuring propane, isobutane, normal butane, natural gasoline and mixes of the
above.
	 
	 	 	For Pressure Reduction (Compressibility).






	 	a.	 	API MPMS, 11.2.2 (GPA 8286) shall be used for measuring propane,
isobutane, normal butane, and mixes of the above.
	 
	 	b.	 	API MPMS, 11.2.1 shall be used when measuring natural gasoline.






	 	 	Temperature and Pressure Correction. API MPMS, 11.3.3.2 Subroutine “PROPYL”
shall be used for temperature and pressure correction when measuring propylene and as a
ratioed factor based upon propylene content in propane/propylene mix.





Section 2.3 Provings and Tolerances.




	A.	 	Principles. During the proving cycle, turbine pulses (volumetric) from the turbine
meter transmitter or mass pulses from the Coriolis transmitter are accumulated. Dividing the
accumulated pulses by the prover volume or prover mass generates a “K Factor” in terms of
volume or mass, respectively. After the initial proving, this “K Factor” is entered into the
flow computer along with a meter correction factor of 1.0000. After subsequent provings, one
can choose to adjust the “K Factor” or the meter correction factor. If the
choice is made to adjust the “K Factor,” then the meter correction factor remains at 1.0000.
If the adjustment is made at the meter correction factor, then the established “K Factor”
remains the same. The densitometer factor is entered into the flow computer to





Storage Lease (Enterprise North Propane-Propylene Splitters)



 









 






	 	 	correct
flowing density in gm/cc as determined by results of a pycnometer test. The pycnometer
shall be installed so that flow through the vessel shall assure proper purging thus allowing
temperature and pressure equalization with the densitometer being proved. Maximum allowable
temperature differential between the contents in the pycnometer and the densitometer shall
be no greater than +/- 0.2 oF. The pressure shall be equal to that of the
densitometer at time of removal.






	B.	 	General.






	 	1.	 	Meter provings, calibration of instruments, and maintenance of measurement
equipment shall normally be performed by EPOLP personnel, but these functions may be
delegated to responsible third-party contractors under the direction of an EPOLP
representative.
	 
	 	2.	 	A customer’s witness signature does not constitute the approval of the use of
out-of-tolerance equipment, but said signature does attest to the validity of the
proving report.






	C.	 	Proving Intervals. Each meter shall be proven when initially placed into service.
Subsequent provings shall be made every thirty (30) days, unless in accordance with the
API MPMS, Chapter 5.3.9.5.2 the consistency of the meter factor, as evidenced in meter
factor control charts, may allow the proving interval to be extended to a maximum of 60 days.
	 
	D.	 	Meter Factor.






	 	1.	 	Volumetric meter proving calculations shall be in accordance with API
MPMS, Chapter 12.2. The average of five (5) consecutive prover runs shall be taken
to establish an initial or new meter factor, provided that the five (5) proving runs
are within 0.0005 (0.05 %) of each other and the meter factor is within 0.0025 of the
previous meter factor under like operating conditions.
	 
	 	2.	 	The new meter factor shall be used after each successful proving if it meets
the above proving criteria.
	 
	 	3.	 	If the new meter factor deviates from the previous meter factor under like
operating conditions by more than plus or minus 0.0025, then one half (1/2) of the
volume measured since the previous proving shall be corrected using the new meter
factor. If the time of malfunction can be determined by historical data, then the
volume measured since that point in time shall be corrected using the new meter factor.
The new meter factor shall not be used to correct volumes measured more than
thirty-one (31) days prior to the new proving.
	 
	 	4.	 	No work shall be performed on the measuring element of a turbine meter without
first proving the meter. If any work is performed, a new meter factor shall be
established.





Storage Lease (Enterprise North Propane-Propylene Splitters)



 









 






	 	5.	 	If the new meter factor deviates more than 0.0025 but less than 0.0050 from the
previous meter factor, the field representatives of EPOLP and the customer shall
determine the corrective action, if any, to be taken.
	 
	 	6.	 	If the new meter factor deviates 0.0050 or more, the element shall be removed
and inspected. If there is build-up on the internals, then the element shall be
cleaned and the meter re-proved. If excessive wear is found, then the element shall be
repaired or replaced and the meter re-proved to establish a new initial meter factor.
After a 24-hour wear-in period, the meter shall be re-proved and if the meter factor
changes more than +/- 0.0025 from the new initial meter factor, then one-half (1/2) of
the volume measured shall be corrected using the latest meter factor.
	 
	 	7.	 	The measurement technician shall record all required corrections to measured
volumes and shall describe the findings, method of repair, and calculations used in
making the correction on the meter proving report. A correction ticket for the amount
of the correction shall be issued.






	E.	 	Density Factor. The proving intervals, tolerances, repairs and methods of correction
are the same as those provided for in Section 2.3.D above, except that the average of two (2)
successive pycnometer provings shall establish product flowing density, provided the two (2)
successive provings agree within 0.0005 (0.05%).





Section 2.4 Custody Measurement Station Failure.




	A.	 	If a failure occurs on a custody measurement station or the station is out of service while
product is being delivered, then the volume shall be determined or estimated by one of the
following methods in the order stated:






	 	1.	 	By using data recorded by any check measuring equipment that was accurately
registering; or
	 
	 	2.	 	By correcting the error if the percentage error can be ascertained by
calibrations, tests, or mathematical calculations; or
	 
	 	3.	 	By comparison with deliveries made under similar conditions when the
measurement station was registering accurately; or
	 
	 	4.	 	By using historical pipeline gain/loss.





Section 2.5 Sampling Procedures.




	A.	 	Flow proportional composite samples shall be removed from the composite sampler at the same
time the meter is read and a custody ticket issued. Samples of finished LPG

	 	 	products streams
shall be analyzed in accordance with ASTM D-2163 and raw mix stream shall be analyzed by GPA
2186 extended analysis for C6+ streams.






	B.	 	Three samples shall be taken from the composite sampler. One sample shall be retained by
EPOLP for analysis, the second sample shall be retained by the customer for analysis, and the
third shall be held as a referee. If EPOLP has taken custody, its sample shall be analyzed
and the analysis used to account for transfer. If the customer has taken custody, its sample
shall be analyzed and the analysis used to account for transfer. If the customer and EPOLP
are in disagreement, then the referee sample shall be taken to a mutually agreed upon
laboratory which shall analyze the sample in accordance with the proper GPA Standard. This
analysis shall be accepted by the customer and EPOLP as final and conclusive for proportions
and components contained in the stream. Charges for such referee sample shall be borne by the
customer and EPOLP equally.






	C.	 	Referee samples shall be held for a period of thirty (30) days from the date of sampling.






	D.	 	If a malfunction of the sampling occurs resulting in no sample being taken or in an
unrepresentative sample being obtained, the following procedure shall be utilized in the order
stated.






	 	1.	 	The sample collected by any on-stream back-up sampling device that has
extracted a sample in proportion to the volume delivered shall be used.
	 
	 	2.	 	An average of the composite samples taken over a mutually agreed time frame
{not to exceed the last three (3) months of properly sampled deliveries} shall be used.
	 
	 	3.	 	Daily grab samples shall to be used for the time in question.





Section 2.6 Definitions.




	A.	 	“Day” shall mean a period of twenty-four (24) consecutive hours commencing at a local time
agreed on by all parties involved.






	B.	 	“Gallon” shall mean a United States Gallon of 231 cubic inches of liquid at sixty degrees
Fahrenheit (60 oF) and at the equilibrium vapor pressure of the liquid.
