JACKSON TWP — The township supervisors Thursday night approved final plans for a new warehouse building and tweaked land development plans for the Bluestone II natural gas processing plant.

ARS will build a 32-by-80-foot warehouse to store its construction equipment on Whitney Drive across from the Sysco Foods facility.

Township manager Chris Rearick said the building will have no electric or other utilities and will only be used for equipment storage.

The supervisors also approved revised plans for the Bluestone II cryogenic gas processing plant, which is under construction.

MarkWest Energy Partners representatives explained the construction pad was moved slightly closer to Hartmann Road because of soil conditions. All other aspects of the development remain the same.

Company representatives told the supervisors it will be about 18 months before they will construct a third gas processing facility at the site.

That site is part of the master plan for the facility and is already approved.

Additional plants could be built there if the demand is warranted, MarkWest officials said. A rail yard also is planned for the site.

The Bluestone II facility, which is slightly larger than another plant at about 80,000 square feet, is being built just east of the existing facility on 30 acres of former farmland.

The first Bluestone plant was built across from the Seneca Landfill and about a mile from the Seneca Valley School District’s secondary schools campus. That plant went operational last summer.

The company is leasing the property from Vogel Disposal Services of Mars, which also owns the Seneca Landfill.

The first Bluestone Plant can process 50 million cubic feet of gas per day.

The Bluestone II plant is projected to process 120 million cubic feet.
