Pittsburgh, PA – The Pennsylvania Department of Environmental Protection (DEP) announced the conclusion of its prompt interim response under the Hazardous Sites Cleanup Act (HSCA) for the Pool Doctor-Beaver Alkali Products Site in Rochester, Beaver County. The site is now clear of hazardous chemicals that had been improperly stored and disposed within and outside buildings on the site. Final restoration of the site—which consisted of final grading, construction of a drainage swale, seeding, and mulching—has been completed.
“Unexpected emergencies like this one, involving potentially deadly chemicals, shows the need for secure funding for the HSCA program,” said DEP Secretary Patrick McDonnell.
On July 1, 2019, DEP initiated the prompt interim response under HSCA to remove and properly dispose of the chemicals at the site to mitigate the threat to human health, safety, and the environment.
When DEP initiated its response, the site consisted of many drums and containers of unknown liquids and solids improperly stored and disposed in dilapidated buildings. These substances were associated with chemical businesses and a laboratory that operated out of the buildings located on the property. This site was not a DEP-regulated facility, but DEP responded when it became aware that the threat of release of unknown substances into the environment posed a public health and environmental risk.
Over the course of its response, DEP—through its contractors—processed approximately 1,000 containers of waste materials, most of which were classified as hazardous. DEP identified and categorized the chemicals inside and outside the buildings and prepared them for disposal or recycling. This survey includes a visual assessment of interior spaces, identification and/or classification, descriptions, and estimated quantities of each chemical.
The site presented significant challenges due to the quantity of unmarked, mislabeled, and incompatible chemicals stored improperly and in deteriorating containers, which was exacerbated by the structural instability of the buildings. Hazardous substances found at the site included strong acids, bases, oxidizers, and solvents. Many of these materials are highly reactive and unstable, strong irritants, flammable, and prone to combustion in sunlight, heat or moisture.
DEP originally allocated $375,000 for its response and to collect, categorize, and properly dispose of miscellaneous chemical wastes removed from the dilapidated facility. Then, a collapsed building that housed a large amount of improperly stored chemicals contributed to a chemical reaction, fire and chemical release at the site on July 12, 2019. As work progressed, DEP found additional storage areas and stock of hazardous chemicals as well as drums buried on the property. This coupled with the cost of addressing structural issues within the remaining building to conduct the work safely, disposal, transport, and 24/7 security for the site led to the total cost exceeding $3 million. A forthcoming final project report will be posted to DEP’s project website and will include the final cost, a full listing of all substances removed, and where they were disposed of.
As required under HSCA, DEP held a public meeting and hearing on September 4, 2019, where it collected public comments. These comments and DEP’s response were added to documents and information gathered by the department to form the basis of the administrative record. The administrative record closed on December 5, 2019, and DEP issued its response to comments and statement of decision to conduct the response action that same day. These documents and other relevant information are available on DEP’s webpage for this matter.
While this phase of its response is complete, DEP continues to investigate any and all potentially responsible parties. DEP retains the right to pursue any site owners or other potentially responsible parties for all costs incurred by DEP during its response. DEP has notified the Borough of Rochester of the completion of the department’s prompt interim response.
