Comments Due: Dec. 12, 2022

The Department invites public comment on a proposal to clean-up the 1400 S. DuPont Site (DE-1796) located at 1400 S. DuPont Highway in New Castle, Delaware. Historically, the Site operated as a fuel filling station and most recently operating as a Getty gasoline station and automotive repair shop from the early 1960s until 2013. Getty gasoline station operations utilize underground storage tank (UST) systems for onsite fuel storage which likely included the handling and transportation of petroleum products at the Site. Several leaking underground storage tanks (LUSTs) were identified and subsequently removed from the Site between 2000 and 2013.

The Site will be subject to the following remedial actions: development and compliance with a Contaminated Materials Management Plan (CMMP); and recording of an Environmental Covenant restricting groundwater withdrawal and Property use to non-residential.

Details of the Proposed Plan are available online at:

The comment period ends on December 12, 2022. For additional information, please contact Kevin Popowich, the DNREC Project Manager at (302) 395-2600 or via email at
