White Oak Mainline Expansion This project is comprised of approximately 7.2 miles of 16 inch diameter pipeline looping and appurtenant facilities in Chester County and 3,550 horsepower of additional compression at the existing Delaware City Compressors Station in New Castle County, DE. The proposed route will use a combination or existing right-of-way and, in some areas, the purchase of easements for facilities or temporary work spaces for construction activities will be needed.

Williams Transco Pipeline New York Bay Expansion Project In Chester County, this project proposes upgrades to the Downingtown Meter Station in East Brandywine as well as at the existing Compressor Station 200, located in East Whiteland Township. More Information Natural Gas Interstate (FERC) Map
Williams Transco Pipeline Northeast Supply Enhancement Project This project is proposed to meet the increasing demand for natural gas in the northeast. Within Chester County, work will be limited to the installation of an electric compressor station at Station 200 in East Whiteland Township. Approximately 35 miles of new pipeline is proposed in Pennsylvania, New Jersey and New York waters along with an additional compressor station in Somerset County, New Jersey.

Texas Eastern/Spectra Energy Marcellus to Market The main goal of the M2M Project is to increase capacity from Texas Eastern's existing Lambertville Station (Hunterdon County, NJ) to Eagle Station (Chester County, PA) while allowing for operational flexibility to manage changing flow directions due to increased receipts at Lambertville Station. Project activity in Chester County would occur at the existing Meter and Regulating (M&R) Station in East Vincent Township and the existing Eagle Station in Upper Uwchlan Township.

Other Regional Projects
Williams Transco Pipeline Atlantic Sunrise The Atlantic Sunrise Project will connect producing regions in northeastern Pennsylvania to markets in the Mid-Atlantic and southeastern states, as far south as Alabama. The preliminary project design includes a total of approximately 178 miles of new greenfield pipe (Central Penn North & Central Penn South), two pipeline loops totaling about 12 miles (Chapman Loop, Unity Loop), two and half miles of existing pipeline replacement, two new compressor facilities in Pennsylvania, and other facility additions or modifications in five states (Pennsylvania, Maryland, Virginia, North Carolina, South Carolina More Information Natural Gas Interstate (FERC) Map
Williams Transco Pipeline Rock Springs The Rock Springs Expansion project is proposed to consist of 11.17 miles of new 20-inch diameter steel pipeline (10.12 miles in Lancaster County and 1.05 in Cecil County) extending from the existing Transco pipeline in Lancaster County, Pa., and terminating at the Wildcat Point facility, approximately five miles from the town of Rising Sun in Cecil County, Maryland. Additionally, Williams is proposing to construct a 4,000 horsepower, electric motor-driven compressor and metering facility at the terminus of the lateral in Cecil County, as well as other piping and valve modifications to existing facilities.

Company, LLC
PennEast Pipeline As proposed, this pipeline will cross through the following counties: Luzerne, Carbon, Northampton and Bucks Counties in Pennsylvania, and Hunterdon and Mercer Counties in New Jersey. It will be a new, 108-mile, 36-inch diameter pipeline and will deliver 1 billion cubic feet of natural gas per day (enough to heat 4.7 million homes). PennEast is planning to co-locate 50% of the pipeline within existing right of ways. More Information Natural Gas Interstate (FERC) Map

Maintenance Notifications

Pipeline operators are required to perform routine maintenance on their lines. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA), federal pipeline regulations contain several provisions that require operation and maintenance requirements. For natural gas pipelines most are found in the Code of Federal Regulations (CFR) Part 192.605, and for hazardous liquids, CFR Part 195.401. This section of the website is devoted to providing information that the county receives from operators regarding these maintenance activities.

Sunoco Logistics Pipeline Work in East Whiteland Township

September 9, 2016 — Sunoco Logistics will be connecting two existing pipelines in East Whiteland Township.  This project will consist of the installation of above ground valves and pipeline.  The current lines are set back approximately 250-feet from Swedesford Road, near the intersection with Bacton Hill Road.  Installation should begin in mid-September and be completed by the end of the year. This connection will allow refined products such gasoline, diesel fuel, and jet fuel to move from Pennsylvania and Delaware refineries to terminals in Allentown, Reading, and Williamsport, PA and Syracuse, Rochester, and Buffalo, NY.
