GENERAL TERMS AND CONDITIONS

11. QUALITY OF GAS (Continued)

11.6 Dust, Gums and Solid Matter. The gas shall be commercially free

from solid matter, dust, gums, and gum forming constituents, or any other

substance which interferes with the intended purpose or merchantability of the

gas, or causes interference with the proper and safe operation of the lines,

meters, regulators, or other appliances through which it may flow.

11.7 Temperature. The gas shall be delivered at temperatures not in

excess of one hundred five degrees Fahrenheit (105°F) nor less than fifty

degrees Fahrenheit (50°F) except where, due to normal operating conditions and

ambient temperatures on the pipeline System, the temperature may periodically

drop below such lower limit.

11.8 Deleterious Substances. The gas shall not contain any toxic or

hazardous substance in concentrations which, in the normal use of the gas, may

be hazardous to health, injurious to pipeline facilities or be a limit to

merchantability.

11.9 Inert Substances. The gas shall not contain inert substances

(carbon dioxide, nitrogen, helium, oxygen, and any other diluent compound) of

more than three percent by volume of which not more than two percent shall be

CO2;provided that TransColorado may post on its Interactive Website that it

will from time to time accept gas from Paradox Basin receipt points which

contains inert substances of up to five percent by volume, of which not more

than two percent shall be CO2.

any of the applicable quality specifications set forth in this Section and

TransColorado notifies Shipper of such deficiency and Shipper fails to remedy

any such deficiency within a reasonable period of time (immediately in those

situations which threaten the integrity of TransColorado's system),

TransColorado may, at its option, refuse to accept delivery pending correction

of the deficiency by Shipper or continue to accept delivery and make such

changes necessary to cause the gas to conform to such specifications, in which

event Shipper shall reimburse TransColorado for all reasonable expenses

incurred by TransColorado in effecting such changes, including operational and

gas costs associated with purging and/or venting the pipeline. Failure by

Shipper to tender quantities that conform to any of the applicable quality

specifications shall not be construed to eliminate, or limit in
