Site Description

The Stimpson property, which is about 21 acres in area, is bounded by undeveloped industrial-zone land to the west and the south, commercial and industrial property to the north, and Sylvan Avenue to the east.

The facility operated for over 25 years, until June 2003. Stimpson made metal fastening products such as eyelets, grommets, washers, rivets and snap fasteners, and the machines used to install the fasteners. In June 2003, Stimpson stopped making these products. Stimpson made all its products in its 200,000-square-foot facility. Stimpson also used a waste water treatment system to clean its tumbling rinse water.  

Site Responsibility and Legal Instrument

All closure activities were done in accordance with the New York State Department of Environmental Conservation (NYSDEC)-approved closure plan.

Permit Status

This facility had interim status to store hazardous waste under the Resource Conservation and Recovery Act (RCRA). In 1985, EPA approved the facility’s request to withdraw its application for a final permit under RCRA. Stimpson kept working as a generator-only facility until it closed in June 2003. However, the facility had to be looked at and cleaned under RCRA’s corrective action program because it originally had been an interim status facility. 

Potential Threats and Contaminants

Metals (copper and zinc), cyanide and oil had contaminated this facility. They have since been removed, and the facility has been clean closed. There are no contaminant threats remaining due to operations of the Stimpson facility. 

Cleanup Approach and Progress

The following activities were done under the approved facility closure plan:

Based on the soil sampling that was done as part of the RCRA closure, four areas were identified as needing remedial actions: (1) the metal finishing area, (2) the former underground settling tanks, (3) the two recharge basins, and (4) the sanitary system‘s leaching pools.

Groundwater has been monitored every three months since 1982 and it has been looked at as part of RCRA closure. The groundwater depth is at around 25 below the ground surface and it flows locally in a southeasterly direction. The last round of groundwater samples showed that groundwater quality has not deteriorated due to past contamination at the site.
