Power line environmental impact statement available

BUSHKILL, Pa. — The Susquehanna to Roseland Transmission Line Right-of-Way and Special Use Permit Final Environmental Impact Statement for the project through the Delaware Water Gap National Recreation Area is now available, the National Park Service announced.

The Final EIS reviews the proposal of PPL Electric Utilities and Public Service Electric and Gas to construct a new 500-kilovolt transmission line, replacing an existing 230-kilovoltline, and has considered six alternative pathways that were proposed for the project.

The two companies have been ordered by JPM, the electric power transmission coordinator for a 13-state area, to upgrade their transmission capabilities. The companies called the existing Susquehanna-Roseland line the «backbone» of west-east power movement.

The new lines would be built on new towers, nearly 180 feet tall, and carry two new 500-kilovolt lines as well as a third set of lines, built to carry 500 kilovolts but initially only carrying the power of the existing 230-kilovolt lines.

Since there are no existing access roads to the 22 towers along the route, more than five miles of new temporary and permanent access roads would be needed for construction and future maintenance.

The National Park Service’s preferred alternative route of the power line would follow the 4.3-mile route of the existing transmission line through the park, with the incorporation of critical mitigation measures, according to the EIS.

The environmentally preferred alternative would be to take no action.

According to the report, replacing the power line would cause significant adverse impacts to geologic resources; wetlands; vegetation; landscape connectivity, wildlife habitat and wildlife; special-status species; rare and unique communities; archeological resources; historic structures; cultural landscapes; socioeconomics; infrastructure, access and circulation; visual resources; visitor use and experience; wild and scenic rivers; and park operations.

Among those impacts are that the construction under the preferred alternate would result in conversion of 20. 28 acres of forested wetlands to scrub shrub and/or emergent wetlands; construction of access roads and crane pads in wetlands (1.02 acres and from drilling activities; 15.22 acres of Exceptional Value Wetlands and/or rare and unique wetlands would be affected, according to the EIS.

It would require clearing 50 to 200 feet of right of way.

About 240 acres of vegetation would be cleared, including 129 acres of mature forest.

Two known archeological sites could be impacted by the project, according to the report. The project would also significantly impact the Old Mine Road because of heavy construction vehicles traversing the road.

In March, the park service identified the preferred alternative, that the proposed Susquehanna-Roseland power line expansion project would follow the route of the existing transmission line, to be evaluated in the final EIS, based on public comments and public meetings.

A Record of Decision, signed by the regional director of the Northeast Region, will be executed by the park service 30 days from the date of publication of the Notice of Availability of the Final EIS in the Federal Register by the Environmental Protection Agency.

Electronic copies of the Final EIS are available for public review online at www.njherald.com and at http://parkplanning.nps.gov/dewa. Hard copies or compact disks of the Final EIS are being mailed to those who have previously requested them. Hard copies are also available at local libraries.
