- Compliance with and maintenance of land and groundwater use restrictions.
On February 13, 2015, EPA issued a Statement of Basis (SB) in which it described the information gathered during environmental investigations at the Facility and proposed a Final Remedy for the Facility.
Consistent with the public participation provisions under RCRA, EPA solicited public comment on its proposed Final Remedy. On February 18, 2015, notice of the SB was published on the EPA website: [https://www.epa.gov/reg3wcmd/publicnotice_ Duke-FormerGM.html] and in the Daily Record newspaper. The thirty (30) day comment period ended on March 20, 2015.
Since EPA did not receive any comments on the SB and EPA has determined it is not necessary to modify the proposed Final Remedy set forth in the SB based on the comment; thus, the remedy proposed in the SB is the Final Remedy selected by EPA for the Facility on March 26, 2015.
EPA’s Final Remedy for the Facility consists of the following:
Below is a summary of the remedial activities that have been conducted at Areas A and D and Sub-parcels B-2, B-4 and C-1 at the Facility.
- Excavated soils that exceeded the soil to indoor air risk-based levels.
- Constructed a 118,000 square foot building (Building 118A) and associated paved parking areas and roadways, and green space areas were covered with a minimum of two feet of clean soil placed over a geotextile marker fabric, thereby eliminating direct contact exposures to soil by the on-site worker, child and youth visitor.
- Implemented a Risk Management Plan (“RMP”) to manage potential direct contact exposures to future construction/excavation workers during activities conducted after the initial redevelopment (e.g., utility maintenance).
- Recorded a deed restriction prohibiting on-site use of groundwater and restricting land use to commercial/industrial purposes throughout Area B.
- Excavated and disposed of soils exceeding the TCLP-lead limit. Constructed a 342,000 square foot building (Building 342) and associated paved parking areas and roadways, and green space areas were covered with a minimum of two feet of clean soil placed over a geotextile marker fabric.
- Implemented a Risk Management Plan to manage potential direct contact exposures to future construction/excavation workers during activities conducted after the initial redevelopment (e.g., utility maintenance).
- Recorded a deed restriction prohibiting the construction of buildings over soils exceeding the soil-to-indoor air screening levels and use of on-site groundwater, in addition to restricting land use to commercial/industrial purposes throughout Area B.
- No active remedial activities were required for soil or groundwater within the Sub-parcel C-1.
- No active remedial activities were required for soil or groundwater within the Area D.
- The primary contaminants are volatile organic compounds, semi-volatile organic compounds, total petroleum hydrocarbons (gasoline range organics and diesel range organics) and RCRA metals
- Currently, deed restrictions affecting the Site prohibit the use of groundwater at the property and restrict the property to commercial and industrial uses.

- Duke developed and implemented a Public Involvement Plan that was approved by the U.S. EPA and MDE early in the project. The Public Involvement Plan outlines procedures to obtain public input and provide opportunities for comment during significant decision-making milestones during the RCRA Corrective Action process. To date, Duke has conducted several public meetings that have included both formal public meetings associated with the regulatory process and informal meetings with Site neighbors and community leaders to discuss redevelopment activities. The public involvement activities have also included focused consultation with neighborhood groups to discuss Site demolition activities, results of environmental assessment activities and plans for future Site development.
- Site is under continued use and/or redevelopment.
- The EPA is dedicated to providing you with timely and accurate information about our work at this site. If you have any questions or concerns, please contact the EPA Project Manager: Leonard Hotham (215)-814-5778.
