Hazardous Waste Cleanup: Mayco Oil and Chemical Company in Bristol, Pennsylvania

On this page:

Cleanup Status

After Mayco ceased operations at the Bristol location in February 1983, the new owner, the Grundy Foundation (Grundy), began to develop the site, as an indoor ice skating rink/recreation center.  Prior to and continuing during construction activities, Grundy had several consultants investigate, evaluate, and report on the environmental condition of the property.  Remedial efforts included razing the Mayco structures and removing identified contaminated soils.  The remediation effort was coordinated with Pennsylvania Department of Environmental Protection (PADEP).  The facility remediated one concrete pit containing dieldrin contaminated sludge, and two areas where black stained soils were visually identified during a PADEP Inspection. Each of these locations were sampled and analyzed for dieldrin (a pesticide), volatile organic compounds (VOCs), and metals as the chemicals of concern (COC).  Dieldrin met the Residential Statewide Health Standard.  Some VOCs and metals in a few soil samples slightly exceeded PADEP’s non-residential Statewide Health Standards, but these exceedances do not statistically contribute to a significant risk to human health or the environment when evaluating the entire facility property.  On November 18, 1997, the Bristol Borough Recreation Authority was given a release of liability in accordance with the PADEP Land Recycling and Environmental Remediation Standards (Act 2) for soil contaminated with dieldrin.

On September 30, 2014, the United States Environmental Protection Agency (EPA) has determined that no further action is required to make this property suitable for any type of land use.  This is based on our findings as detailed in the Statement of Basis (SB).  This determination is consistent with EPA’s February 2003 Final Guidance on Completion of Corrective Action Activities at Resource Conservation and Recovery Act (RCRA) Facilities (reference 68 FR 8757).
