5.3 El Paso agrees that interconnect Receipt Points on El Paso's

system, where gas does not conform to the carbon dioxide

and/or the total diluent specification set forth in Sections

5.1(e) and (f) above, shall be grandfathered based on the

twelve (12) month average non-conforming percentages of carbon

dioxide and total diluents for the twelve (12) month base

period ended July 31, 1990. El Paso shall accept gas with

carbon dioxide and/or total diluents at percentages up to the

grandfathered non-conforming specifications at volumes up to

the historical volume. The historical volume is deemed to be

the daily average volume received by El Paso at each of the

non-conforming interconnect Receipt Points for the twelve (12)

month base period ended July 31, 1990. The identification of

the non-conforming interconnects, the grandfathered

specifications and the historical volumes are set forth on the

following table:
