The Department invites public comment on a proposal to clean-up the 17399, 17403, 17439 S. DuPont Highway Site (DE-1791) located at 17399, 17403, and 17439 S. DuPont Highway in Harrington, Delaware. Historically, the Site was utilized by Coastal Pump & Tank since at least the 1970s. Coastal Pump and Tank operations include service and maintenance of underground storage tank (UST) systems which likely included the handling and transportation of petroleum products at the Site. Operations related petroleum release occurred on the property in 1994. However, a 14-year bioremediation plan addressed the impacted soils and concluded in 2008.
The Site will be subject to the following remedial actions: characterize remaining contents of unused drums and ASTs for proper disposal; excavate soil/fill material located at sample location COMP-2 for proper disposal; groundwater use restrictions; compliance with a contaminated materials management plan; and compliance with a long term stewardship plan
Details of the Proposed Plan are available online at: den.dnrec.delaware.gov/
The comment period ends on November 29, 2022. For additional information, please contact Kevin Popowich, the DNREC Project Manager at (302) 395-2600 or via email at RS_Public_Comments@delaware.gov.
