Redevelopment at the Site

The 330-acre Sharon Steel Corporation (Farrell Works Disposal Area) Superfund site is located in Mercer County, Pennsylvania, near the Pennsylvania/Ohio state border. Starting in 1900, the Sharon Steel Corporation used the area to dispose of furnace slag and sludge. From 1949 to 1981, site operators dumped millions of gallons of waste acid over the slag to try to neutralize the acid. Leachate from the slag and sludge migrated into soil and groundwater, leaving the site contaminated. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1998. In 2000, under a Prospective Purchaser Agreement (PPA), EPA worked with a local company to reuse the slag at the site for construction and road projects. In 2006, EPA divided the site into two Operable Units (OUs) so that two ongoing businesses (an asphalt plant and trucking company) located on the OU2 property could continue to operate throughout the cleanup process. Also in 2006, EPA selected a remedy for the OU1 property that includes re-grading, contouring and treating contaminated slag and sludge with a biosolids cap; stabilizing eroded banks next to a river; placing restrictions on land and groundwater use to protect the remedy; and developing a long-term monitoring plan for groundwater, surface water and sediment at the site. The OU1 remedy will be built in two phases to allow the continued beneficial recovery of slag in the 230-acres southern portion of OU1. For the northern portion of OU1 (71 acres), EPA, through an agreement with the Pittsburgh District of USACE, has updated the 2012 remedial design and is expecting to award a construction contract and start construction in 2018. Once completed and re-vegetated, the area may well serve recreational users. For example, the design for the northern portion of OU1 includes a hiking trail.
