ANCHORAGE, Alaska (AP) — A proposal for an in-state natural pipeline that could carry North Slope natural gas to communities from Fairbanks to southcentral Alaska has been revised to eliminate the transport of natural gas liquids, which will have the effect of lowering tariffs for customers in Fairbanks.

Carrying natural gas liquids such as ethane, propane and butane was previously considered desirable because they could be sold at a premium and used to lower the price of gas to Alaskans, said Frank Richards, the pipeline engineering manager for the Alaska Gasline Development Corp.
