The state Department of Environmental Protection has declared that “remediation is complete” at the former Rouseville Refinery north of Oil City.
After the seepage of crude oil and other petroleum products was discovered in Oil Creek and Cherry Run, cleanup efforts concentrating on those waterways began in 1990. Refinery operations continued at the site until 2002. More recent cleanup work has involved both soil and water decontamination through guidelines set down by the Pennsylvania Land Recycling Program. Final efforts, according to a DEP statement released this week, included the recovery and treatment of contaminated groundwater and petroleum products, the removal and capping of contaminated soil, and the installation of “engineering controls” to address the migration and use of groundwater at the site.
Four different companies have recently been redeveloping various areas of the property where refinery operations first began in the late 1800’s.
