Transco's New York Bay expansion project clears FERC staff review

FERC Office of Energy Projects staff signed off on a proposal to expand natural gas services to New York City.

FERC staff concluded that the New York Bay expansion project would not significantly affectthe quality of the environment, if constructed and operated with certain mitigatingmeasures.

"We recommend that the commission order contain a findingof no significant impact," staff said in the April 4 environmental assessment,or EA, with the mitigating measures added as conditions of the approval.

On July 8, 2015, the WilliamsPartners LP subsidiary applied to build and operate facilities thatwould make up the New York Bay expansion project. The construction and replacementof pipeline facilities would take place in Chester County, Pa.; Richmond County,N.Y.; and Middlesex and Essex counties, N.J.

"The project would enable Transco to provide an additional115 MMcf/d of firm transportation service to the [Brooklyn Union Gas Co.], d/b/a National Grid New York,"staff said. The additional service would help address National Grid's needs forthe 2017-2018 winter heating season.

To serve National Grid, Transco has proposed to replace threeportions of the Lower New York Bay lateral pipeline with 0.25 mile of 42-inch-diameterpipeline and uprate the pipeline's total operating pressure from 960 pounds persquare inch gauge to 1,000 psig.

The project would also include aboveground work, such as upratingCompressor Station 200 in Chester County to 33,000 horsepower, and uprating CompressorStation 303 in Essex County to 27,500 hp; adding 11,000 hp of electric-driven compressionat a compressor station in Middlesex County, N.J.; and installations and modificationsat three meter and regulation, or M&R, stations in Chester County, MiddlesexCounty and Richmond County. The work on the M&R station in Richmond County wouldinclude a temporary M&R station during construction.

Transco has planned an in-service date of Nov. 1, 2017. The companyexpects to begin construction on a portion of the project in December 2016, withconstruction on other components beginning in April and May 2017. (CP15-527)
