The federal Environmental Protection Agency is proposing a remediation plan for unused land that formerly housed a chemical facility in Beaver County. The former ARCO Chemical property, which is near the current Nova Chemicals site along the Ohio River, has been unused for decades and is heavily contaminated. The Beaver County Times reports the EPA’s plan only covers inactive portions of the property, but the agency intends to propose a similar plan for the active section of land currently owned by Nova, according to a legal notice published on Monday.
