The Department of Natural Resources and Environmental Control (DNREC) Remediation Section (RS) has adopted a plan regarding the clean-up of the Black Oak Development Operable Unit -2 (OU-2) Site (DE-1863) (Site) located in Lewes. The Site was historically used for agricultural purposes and consists of approximately 24 acres of a larger 77-acre parcel. The site has been divided into two operable units. OU-1, consisting of the soil, has been remediated under a separate Proposed Plan of Remedial Action (Proposed Plan). OU-2 consists of groundwater and soil vapor.

DNREC-RS issued a public notice of the Proposed Plan for the Black Oak Development OU-2 Site on November 12, 2025. There were no comments or questions from the public regarding the Proposed Plan.
