In June 1990, EPA conducted an on-site RCRA Facility Assessment (RFA). The assessment resulted identified 15 solid waste management units (SWMUs) and five other Areas of Concern (AOC).
In October 1998, Southdown discontinued the use of Hazardous Waste Derived Fuels. As a result, a closure plan for hazardous waste storage and blending units was submitted to Pennsylvania Department of Environmental Protection (PADEP) for approval.
In May 2000, EPA visited the Southdown plant to provide additional data to evaluate the environmental indicators. EPA learned that 5 of the 15 SWMUs were removed, 3 were inactive, 2 were under PADEP’s closure, and 5 were still active. All the AOCs were still active except the underground gasoline tank, which was closed and removed in accordance with the PADEP Underground Storage Tank requirements
In June 2000, Southdown submitted revised closure plan to PADEP for approval.
In September 2000, PADEP approved the revised closure plan.
RCRA Corrective Action activities at the Southdown Wampum facility are being conducted under a joint effort by EPA and PADEP. The investigation and any necessary clean up activities have been implemented in accordance with a closure plan that was required by PADEP in 2000.
In February 2001, Southdown ceased performing groundwater investigations at the permitted hazardous waste container area and the truck off-loading pad with PADEP approval.
In August 2001, EPA completed an evaluation of available information and issued “Yes” determinations for “Migration of Contaminated Groundwater Under Control” and “Current Human Exposures Under Control” Environmental Indicators (EI).
There are no institutional controls at this time.EPA will issue a RCRA corrective action public notice in local newspaper that will explain the proposed no further action and provide public an opportunity to review and comment on this proposal.
The Cemex Wampum Facility, formerly known as Southdown, encompasses approximately 70 acres of land, located in Lawrence County, Pennsylvania, on Route 18, approximately 2 miles south of Borough of Wampum. The facility is bounded by the Beaver River to the east and Route 18 to the west. The facility houses three kilns, numerous silos, a clinker dome, and other buildings and storage units throughout the plant. The immediate land use surrounding Southdown is primarily undeveloped.
