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 (105øF) nor less than

fifty degrees Fahrenheit (50øF) 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.

11.10 Operators Failure to Meet Specifications. If, at any time,

gas tendered by Shipper for transportation shall fail to substantially

conform to 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
