The Department invites public comment on a proposal to clean-up the 1175 East 7th Street Site (DE-1775) [“Site”] located at 1175 East 7th Street in Wilmington. Historically, the Site was used as a municipal landfill for the City of Wilmington. It is currently overgrown with vegetation.

The Site will be subject to the following key remedial actions: placement of a cap consisting of impervious material, such as asphalt or concrete, or at least one feet of DNREC-approved fill material, the recording of an Environmental Covenant with the property deed that restricts property use to non-residential and also groundwater withdrawal and required compliance with the site-specific Contaminated Materials Management Plan (CMMP) and Long-Term Stewardship (LTS) Plan.
