Adelphia Gateway 

Adelphia Gateway, LLC is proposing a project to repurpose an existing pipeline in Southeastern Pennsylvania from oil to natural gas. This project, subject to review by the Federal Energy Regulatory Commission (FERC), also requires approvals and permits from the Pennsylvania Department of Environmental Protection (DEP). This web page has been created to house and share materials and updates from DEP. 

Air Quality 

PA DEP reviewed and approved two plan approval applications for the construction and operation of two new natural gas compressor stations. Air quality plan approvals are intended to address air pollution sources and applicable control devices. After a thorough and complete review of the application, DEP generates a plan approval that contains specific conditions, including monitoring and recordkeeping, that will ensure the construction and operation are conducted in compliance with applicable rules and regulations. 

DEP accepted public comments on its two draft plan approvals from November 3, 2018, until December 14, 2018. All comments received during the comment period were reviewed and responded to in the comment response documents above.

DEP also held two public hearings to receive comments. The hearings were held on Tuesday, December 4, 2018, from 7 PM – 9 PM at the following locations:

  • Lower Chichester Township Municipal Building, 1410 Market Street, Linwood, PA  19061
  • West Rockhill Elementary School- cafeteria, 1000 Washington Ave, Sellersville, PA 18960

Copies of the hearing transcripts are available above.

Construction and operation of these compressor stations cannot begin until all necessary local, state and federal approvals are received.

The Pennsylvania Department of Environmental Protection (DEP) operates under Title 25 of the Pennsylvania Code. Under that code, environmental approvals, permits and/or certifications will be required for this project. DEP reviewed two permit applications submitted to the Air Quality (AQ) program and is currently reviewing eight applications submitted to the Waterways Engineering and Wetlands (WAW) program. The WAW permits fall under the jurisdiction of Chapter 102 and Chapter 105. The WAW permit reviews are also coordinated with the United States Army Corp of Engineers and/or local County Conservation Districts. The process consists of administrative/completeness and technical reviews. Once an application is received and deemed complete, the technical review will proceed, and copies of the application and supplemental information will be posted below.

Ch. 102 - Erosion & Sediment Control Permit

The ESCGP-3 permit authorization will be required for the entity proposing or conducting earth disturbance activities to develop, implement and maintain Best Management Practices (BMPs) to minimize the potential for accelerated erosion and sedimentation and to manage post construction stormwater.

Ch. 105 - Water Obstruction and Encroachment Permits

State 401 Water Quality Certifications (WQC) are issued by each state the project is in. The state must evaluate whether the proposed project will be constructed in a manner that achieves the state's water quality standards. The WQC may be issued with conditions upon the applicant acquiring permits, authorizations, or approvals required under existing state water quality programs.
