Comments Due: Jan. 3, 2022

The Department invites public comment on a proposal to clean-up Operable Unit 1 (OU-1) of the SIP Property Site (DE-1408) [“Site”] located at 1101 East 8th Street in Wilmington. Historically, the Site was used as part of shipbuilding operations. OU-1 of the Site is currently largely wooded but the southeastern corner was cleared and has a building and parking lot on it.

OU-1 of 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 required compliance with the site-specific Contaminated Materials Management Plan (CMMP) and Long-Term Stewardship (LTS) Plan.

Details of the Proposed Plan of Remedial Action are available online at:
