The Federal Energy Regulatory Commission said in an Aug. 1 notice that its staff will prepare an environmental assessment (EA) on the 2017 Expansion Project, involving construction and operation of facilities by Eastern Shore Natural Gas Co. in Lancaster and Chester counties, Pennsylvania; Cecil County, Maryland; and New Castle, Kent, and Sussex counties, Delaware.
The commission will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. Comments on what should be covered in the EA are being taken until Aug. 31.
The 2017 Expansion Project facilities consist of: approximately 30 miles of pipeline looping in Pennsylvania, Maryland and Delaware; upgrades to existing metering facilities; installation of an additional 3,550 horsepower (hp) compressor unit at the existing Daleville Compressor Station; and approximately 17 miles of new mainline extension and the addition of two pressure control stations in Sussex County, Delaware.
The project broken down by state consists of:
- Honey Brook Meter and Regulator Station: Replace existing meter runs and pressure/flow control valves at the existing interconnect site with Texas Eastern Transmission LP. Modify the existing Honey Brook Meter and Regulator Station and lateral piping to accommodate the installation of upsized mainline taps and valves and the installation of a filter separator, associated piping, and storage tank as well as other ancillary equipment at Eastern Shore’s existing interconnect with Texas Eastern. All construction work would be conducted within the fenceline in previously disturbed areas of the existing interconnect site.
- Parkesburg Loop: Construct approximately 5 miles of 16-inch-diameter pipeline loop1 beginning at Eastern Shore’s existing Parkesburg Meter and Regulator Station southward to Lime Stone Road (PA-10).
- Jennersville Loop: Construct approximately 7 miles of 24-inch-diameter pipeline loop beginning at Eastern Shore’s existing Daleville Compressor Station southward to Hess Mill Road.
- Daleville Compressor Station Upgrade: Install a new 3,550 hp gas-fired compressor unit at the existing Daleville Compressor Station.
- Fair Hill Loop: Construct approximately 6.3 miles of 24-inch-diameter pipeline loop beginning at Eastern Shore’s existing block valve on Walker Road in Chester County, Pennsylvania southward to Cecil County, Maryland, to tie into the existing Eastern Shore pipeline north of Route 2 near the Maryland/Delaware state line.
New Castle County
- Middletown Loop: Construct approximately 1 mile of 10-inch-diameter pipeline loop beginning on Peterson Road and extending to a location southeastern of Industrial Road. Construct approximately 0.65 mile of 6-inch-diameter pipeline lateral and meter station from Industrial Road towards Auto Park Drive.
- Summit Loop: Construct approximately 0.5 mile of 10-inch-diameter pipeline loop starting along the south side of C&D Canal at Eastern Shore’s existing 12- inch aerial crossing southward to tie into the existing Eastern Shore pipeline.
- Woodside Loop: Construct approximately 5 miles of 16-inch-diameter pipeline loop beginning in Wyoming, Delaware southward to Viola, Delaware.
- Hearns Pond Loop: Construct approximately 1.5 miles of 10-inch-diameter pipeline loop along U.S. 13 near Seaford southward to Eastern Shore’s existing Seaford Pressure Control Station.
- Seaford to Millsboro Segment: Construct approximately 17.0 miles of 10-inch-diameter pipeline extension from Seaford eastward to Eastern Shore’s existing Millsboro Meter & Regulator Station near Millsboro.
- Laurel Loop: Construct approximately 5.1 miles of 10-inch-diameter pipeline loop along U.S. 13 near Laurel southward to connect with Eastern Shore’s existing pipeline.
- Pressure Control Stations: Construct two pressure control stations located near the towns of Millsboro and Delmar.
