Final Plan of Remedial Action for 1190 East 7th Street Site (DE-1410)

Division of Waste and Hazardous Substances

Published: July 28, 202

The Department has adopted a plan regarding the clean-up of the 1190 East 7th Street Site (DE-1410) located at 1190 East 7th Street in Wilmington. Historically, the Site was the location of railcar manufacturing operations and subsequently a city municipal landfill but has most recently remained undeveloped and wooded.

The Site will be subject to the following key remedial actions: capping of soil, recording of an environmental covenant with the property deed restricting site use to non-residential type uses, restricting interference with the cap, limiting groundwater withdrawal, and requiring compliance with the DNREC-approved Long-Term Stewardship Plan and Contaminated Materials Management Plan.

DNREC issued a public notice of the Proposed Plan for the 1190 East 7th Street Site on
June 23, 2021. There were no comments or questions from the public regarding the Proposed Plan. Details of the Final Plan are available online at:
