Merrion Oil & Gas  

Merrion Oil & Gas is proposing to drill and operate an unconventional gas well site on U.S. Steel's Edgar Thomson Plant property. The property is located primarily in North Versailles Township, but also includes East Pittsburgh and North Braddock Borough, all in Allegheny County. This project requires approvals and permits from the Pennsylvania Department of Environmental Protection (DEP) and may require permitting or approvals from the Allegheny County Health Department (ACHD) which oversees air quality issues in Allegheny County.  

The project involves construction of an unconventional gas well pad, two access roads, and five freshwater storage tanks. Additionally, Merrion Oil and Gas Corporation intends to construct a 2,770 ft natural gas pipeline and a 2,990 ft freshwater pipeline. The proposed project area is located on property owned by US Steel at the Mon Valley Works Edgar Thompson Steel Plant, which would be the sole consumer of the natural gas extracted. A portion of the site will discharge stormwater to the North Braddock Borough MS4 Storm Sewer System along Braddock Ave. Other portions of the site will discharge or have the potential to discharge stormwater to Turtle Creek and unnamed tributary (T64495) to Turtle Creek (WWF, Siltation-Impaired, TMDL-impaired (metals, pH)). Total Disturbed Area is 13.4 acres.
