Staff of the Federal Energy Regulatory Commission (FERC) has prepared a favorable Environmental Assessment (EA) of Tennessee Gas Pipe Line Co LLC.’s (TGP) proposed Triad Expansion Project [CP15-520]. FERC staff concluded that the project, with appropriate mitigating measures, would not adversely affect the environment, according to the EA. The EA comes nearly a year after TGP filed for a certificate with FERC to expand its system in Pennsylvania by 180,000 Dth/d to serve a new natural gas-fired power plant in the northeast part of the state (see Daily GPI, June 19, 2015). The $87.4 million project would consist of constructing seven miles of 36-inch diameter pipeline looping and include the installation of new a pig launcher and crossover and connecting facilities, as well as modifications to an existing compressor station. TGP said the construction and modifications would occur on its 300 Line, which runs from Mercer County, PA, eastward through the state and into others before ending in Massachusetts. The expansion would deliver natural gas to an existing interconnection with utility UGI Corp., which would then deliver the gas from Susquehanna County directly to the new power plant in Lackawanna County, PA, TGP said. FERC will take comments on the EA through July 15.
