12.1 Heat Content. The gas delivered at each of the points of receipt and delivery shall
contain a gross heating value of not less than 950 Btus per cubic foot nor more than
1,150 Btus per cubic foot.
12.2 Merchantability. The gas shall be commercially free from dust, gums, gum-forming
constituents, dirt, impurities or other solid or liquid matter which might interfere with
its merchantability or cause injury to or interference with proper operation of the
pipelines, regulators, meters, or other equipment of Overthrust. The gas shall also be
free of all matter that is deemed hazardous or toxic and is subject to regulation by
the Environmental Protection Agency or any State agency having similar jurisdiction
or authority.
12.3 Hydrogen Sulfide. The gas shall not contain more than .25 grain of H2S per 100 cubic
feet.
12.4 Total Sulfur. The gas shall not contain more than 5 grains of total sulfur per Mcf, of
which not more than 2 grains shall be mercaptan sulfur.
12.5 Oxygen. The gas shall not at any time have an oxygen content in excess of ten parts
per million by volume, and the parties shall make every reasonable effort to keep the
gas free of oxygen.
12.6 Temperature. The gas shall be delivered at a temperature not in excess of 120
degrees Fahrenheit or less than 35 degrees Fahrenheit.
12.7 Inert Substances. The gas shall not contain combined inert substances of more than
three percent by volume, of which not more than two percent shall be carbon dioxide.
12.8 Water Vapor. The gas shall not contain water vapor in excess of five pounds per
million cubic feet.
12.9 Cricondentherm Hydrocarbon Dew Point (CHDP).
(a) CHDP Limit - Overthrust will accept all deliveries of natural gas with a CHDP equal
to or less than 15 degrees Fahrenheit provided that such gas satisfies all other
applicable provisions of Overthrust's FERC Gas Tariff.
(b) CHDP Operating Limit - Overthrust may, from time to time, as operationally
feasible, establish and post on its internet web site a CHDP Operating Limit that is
higher than the CHDP Limit for natural gas received into its system on specified
CHDP zones. Overthrust's ability to establish and post higher CHDP Operating
Limits for particular zones will depend on operating characteristics such as
pressures and temperatures, blending capability of prevailing and expected gas
supplies and proximity to downstream city-gates and interconnecting pipelines.
(c) Overthrust shall not be obligated to accept gas into its system that exceeds the
posted CHDP Operating Limit. Establishment of CHDP Operating Limits shall not
be deemed to negate, reduce or limit Overthrust's authority to issue Operational
Flow Orders. To the extent operationally practicable, Overthrust may waive its
posted CHDP Operating Limit for gas received from certain points on its system
provided such waiver is made on a non-discriminatory basis.
12.10 CHDP Operating Limit Posting Procedure.
(a) Overthrust may post a CHDP Operating Limit at or above the CHDP Limit for each
CHDP zone. The posted CHDP Operating Limit will apply to all receipt points
within that CHDP zone. CHDP zones will be identified on Overthrust's Internet
web site. Overthrust will provide as much prior notice of changes to its CHDP
Operating Limits as possible and attempt to provide at least two days notice prior
to the Cycle One nomination deadline. However, Overthrust may reduce the
CHDP Operating Limit to the CHDP Limit at any time without notice, when
operationally necessary. In such event, Overthrust will post a critical notice on its
Internet web site.
(b) Overthrust will provide as much notice as reasonably practical of any revisions to
its CHDP zones. However, in no event will the notice be less that 30 days.
(c) For receipt points with online chromatographs, Overthrust shall post on its
internet web site the prior gas day average and maximum calculated CHDP at
each receipt point. For receipt points without online chromatographs, once per
month Overthrust shall post on its internet web site the average and maximum
calculated CHDP at each receipt point for the prior month period. Compliance with
CHDP limits will be determined based on calculated current flowing CHDP
temperatures.
(d) CHDP Calculation. Overthrust shall perform the CHDP calculations using an
industry recognized equation of state and natural gas chromatograph
compositional analysis through C9. In the event of a dispute over calculated CHDP
temperature at a given receipt point, Overthrust's calculated value shall control
unless the disputing party can clearly identify the cause of the error.

FERC Gas Tariff Shipper’s Failure to Meet Specifications
Third Revised Volume No. 1-A Section Version: 0.0.0
Filed On: August 18, 2010 Effective On: August 18, 2010
12.11 Shipper's Failure to Meet Specifications. Should any gas tendered for receipt by
Overthrust fail at any time to conform to any of the specifications of this tariff,
Overthrust shall have the right, upon notification to Shipper, to refuse to accept all or
any portion of such non-conforming gas until such time as Shipper demonstrates to
Overthrust's satisfaction that the gas meets Overthrust's quality specifications. Such
refusal by Overthrust to receive non-conforming gas shall not relieve Shipper of any
of its obligations under this tariff. Overthrust may, on a nondiscriminatory basis,
elect to receive non-conforming gas in such quantities and for such time periods as
Overthrust determines will not jeopardize its ability to meet its obligations to its
customers or endanger the safe operation of its transportation system.

FERC Gas Tariff Quality of Overthrust’s Deliveries
Third Revised Volume No. 1-A Section Version: 0.0.0
Filed On: August 18, 2010 Effective On: August 18, 2010
12.12 Quality of Overthrust's Deliveries. Overthrust shall not be required to process, treat
or otherwise condition Shippers' gas to meet the quality specifications of downstream
pipelines or end users, including Shipper. Overthrust shall deliver to Shipper gas
which meets the quality specifications set forth in §§ 12.1 through 12.10.
12.13 Commingling. Gas received from Shipper will be commingled with the gas of other
Shippers in the system. Accordingly, the gas of Shipper shall be subject to such
changes in gross heating value per cubic foot and other specifications as may result
from such commingling.
