GENERAL TERMS AND CONDITIONS
14.4 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
14.5 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.
14.6 Temperature. The gas shall be delivered at a temperature not in
excess of 120 degrees Fahrenheit or less than 35 degrees Fahrenheit.
14.7 Inert Substances. The gas shall not contain inert substances of
more than three percent by volume.
14.8 Water Vapor. The gas shall not contain water vapor in excess of
five pounds per million cubic feet.
14.9 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
(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
14.10 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.
