Adelphia Gateway

Adelphia Gateway, LLC, is proposing a project to repurpose an existing pipeline in Southeastern Pennsylvania from oil to natural gas, traversing Northampton, Bucks, Montgomery, Chester and Delaware Counties. 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).

Below is information on DEP's review and approval of the permit applications and other useful project information. The material is presented here to enable the public to readily review the application material, any noted technical deficiencies and the company's responses to the technical deficiencies. Additional materials will be added to the site as the Department continues with its review of the permit applications. Persons wishing to schedule a file review for this project should contact the Southeast Regional Office for Records Review at 484-250-5910.

For those unfamiliar with DEP’s regulatory jurisdiction, DEP has the authority to review and make decisions on permit applications pursuant to environmental regulations such as:

Chapter 102, Erosion and Sediment Control which regulates erosion and sedimentation resulting from earthmoving activities. A pipeline project that exceeds five acres of total earth disturbance must obtain an Erosion Control Permit with plans and practices to control stormwater runoff both during and following earthmoving activities;

Chapter 105, Dam Safety and Waterway Management which regulates water obstructions and encroachments focused on activities located in, along, or across wetlands, lakes, streams and floodways;

For some pipeline projects, DEP also processes a State Water Quality Certification. Pursuant to Section 401 of the Federal Clean Water Act, DEP will ensure that activities associated with proposed interstate natural gas transmission pipeline projects regulated by the Federal Energy Regulatory Commission (FERC) comply with state water quality standards. This certification is often authorized conditionally and serves as an index for all DEP water-related permits/approvals that may be required for a pipeline project to demonstrate compliance with state water quality standards.

The reviews of these permit applications are often coordinated with other DEP Programs including, but not limited to, Clean Water (NPDES Permitting for Discharges from Hydrostatic Testing), Air Quality (Air Quality Permitting), Solid Waste Management, Oil and Gas Management, and Bureau of Mining Programs. DEP may also coordinate the review of these permits with other agencies such as County Conservation Districts, the PA Fish and Boat Commission, the PA Game Commission, the PA Department of Conservation and Natural Resources, the PA Department of Agriculture, the PA Historic and Museum Commission, the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service and the River Basin Commissions. Please note that this is not an all-inclusive list of agencies and the type of activity associated with the project will dictate the agencies that will be involved.

DEP’s authority is limited regarding pipeline projects. For instance, DEP’s authority does not cover determination of the overall pipeline route, pipeline safety, or property rights such as eminent domain. Those issues may fall under the jurisdiction of other agencies such as the Federal Energy Regulatory Commission (FERC), the Pipeline Hazardous Materials Safety Administration (PHMSA) or the Pennsylvania Public Utility Commission (PUC).

Adelphia Gateway Project Overview

Information Sheet

This information sheet (PDF) provides a summary of the project and current status.

State Water Quality Certification

On February 28, 2020, DEP issued a conditional State Water Quality Certification. The conditional State Water Quality Certification was published in the Pennsylvania Bulletin on March 14, 2020.

On October 25, 2019, Adelphia Gateway provided a response for the technical deficiencies they received from DEP on August 16, 2019 for the 401 State Water Quality Certification.

On August 16, 2019, DEP sent the following technical deficiency letter to Adelphia Gateway for the 401 State Water Quality Certification.

On March 4, 2019, DEP received a request for a state water quality certification which evaluates whether the proposed project, will be constructed in a manner that achieves Pennsylvania’s state water quality standards. The request for State Water Quality Certification was published in the Pennsylvania Bulletin on March 16, 2019. Submitted public comments were evaluated by DEP prior to the request being approved.

Chapter 102 and 105 Permit Applications

On June 15, 2020, DEP sent the following incompleteness review letter to the applicant for its Chapter 102, Erosion and Sediment Control Permit Application.

On May 18, 2020, DEP received a response for the Chapter 102, ESCGP-3 technical deficiencies from Adelphia Gateway

On April 24, 2020, DEP sent the following technical deficiency letter to the applicant for its Chapter 102, Erosion and Sediment Control Permit Application.

On March 24, 2020, DEP received a response for the Chapter 102, ESCGP-3 technical deficiencies from Adelphia Gateway.

On February 25, 2020, DEP sent the following technical deficiency letter to the applicant for its Chapter 102, Erosion and Sediment Control Permit Application.

On January 9, 2020, DEP considered the Chapter 102, Erosion and Sediment Control Permit Application complete and commenced its technical review. The following completeness review letter were sent to the Applicant.

On March 18, 2019, DEP received the following Chapter 102, Erosion and Sediment Control Permit Application.

On August 6, 2018, DEP received Chapter 105, Water Obstruction and Encroachment General Permit Applications No. 8 and No. 11 for the construction, operation, and maintenance of temporary road crossings; and for the maintenance, testing, repair, rehabilitation or replacement of water obstructions and encroachments, respectively.

Air Quality

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.

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

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 program and is currently reviewing applications submitted to the Waterways Engineering and Wetlands program.
