FERC staff will prepare an environmental assessment of Transcontinental Gas Pipe Line Co.'s (Transco) proposed Gateway Expansion Project in New Jersey, the regulatory agency said Tuesday.

The Federal Energy Regulatory Commission is accepting comments on the project through Feb. 2 [CP18-18].

Transco filed at FERC in November for a certificate of public convenience and necessity authorizing it to construct and operate Gateway Expansion Project. The project would enable Transco to provide an additional 65,000 Dth/d of firm transportation service to PSEG Power LLC and UGI Energy Services LLC to serve their incremental supply needs beginning with the 2020-2021 winter heating season, according to the application.

The expansion would provide 55,000 Dth/d from Transco's existing Station 210 pooling point and from PennEast Pipeline's proposed interconnection with Transco, both in Mercer County, NJ, to an existing interconnection with PSEG at the Ridgefield meter and regulating station in Bergen County, NJ.

Another 10,000 Dth/d would be provided from project receipt points to an existing interconnection with PSEG at the Paterson meter and regulating station in Passaic County, NJ.

The project would include the addition of 27,500 hp at Transco's existing compressor station 303 in Essex County, NJ, and other associated modifications in the area. No additional pipeline or pipeline looping is required, according to the application.

Transco has said it executed binding precedent agreements with project shippers for 100% of the firm transportation service to be provided through the project.

Transco requested approval of the project by November 2018 in order to meet a target in-service date of Nov. 1, 2020.
