MPLX LP Subsidiary MarkWest Energy Partners LP plans to start construction on a 200 MMcf/d natural gas processing facility in southwest Pennsylvania this month, according to plans submitted to local authorities.

The Harmon Creek Complex, formerly the Fox Complex, was renamed after it was put on hold. As the commodity outlook improved last year, MarkWest revived the project. It is to include two cryogenic units and a de-ethanizer facility. The site could ultimately accommodate four cryogenic units and two de-ethanizers.

Construction is to continue until April before the facility, which would also include 20,000 b/d of de-ethanization capacity, comes online next year, MarkWest said. The facility is being built in Washington County’s Smith Township, near a cryogenic processing facility now underway by Energy Transfer Partners LP (ETP), which is part of its $1.5 billion Revolution System project.

Township supervisors earlier this month scheduled another hearing for Sept. 7 on MarkWest’s conditional-use permit, as both sides work toward approval. Construction activities at ETP’s site, approved by the township last year, has created issues for residents that have complained about truck traffic, according to media reports. The supervisors want those issues resolved before they move forward with MarkWest’s permit.

Supervisors are expected to meet with MarkWest this month to discuss what improvements should be made to the local roads. After that, a grading permit could be issued that would allow the company to begin construction.

ETP is currently constructing a complete rich-gas solutions system in the region that would include 110 miles of natural gas gathering pipeline, the cryogenic plant, natural gas liquids pipelines and a fractionation facility. The Revolution System is expected to enter full service sometime late this year.
