The Department invites public comment on a proposal to clean-up the Deerfield Farms Site [‘Site’] (DE-1701) located off of West Denneys Road in Dover, Kent County, Delaware. The Site consists of undeveloped woodlands and wetlands with a small mowed upland area in the northern portion. The eastern Site boundary is adjacent to a railroad easement and the Cahoon Branch transects along the southern Site boundary. By the late-1990s, much of the wooded areas of the northern central portion of the Site had been cleared from the area identified as the historical fill area in the Brownfield Investigation (BFI) Report. Furthermore, the Site is also located down-range of a former small arms firing range that was operated by the Delaware State Police from the late-1960s until the mid-2000s.

Deerfield Farms will be subject to the following key remedial actions: the recording of an Environmental Covenant restricting groundwater withdrawal; and the submittal of a Contaminated Materials Management Plan (CMMP).

Additionally, based on the findings of the BFI Report, there is no unacceptable risk associated with the historical fill area. However, the fill contains trace amounts of solid waste outside the scope of the Regulations Governing Hazardous Substance Cleanup (HSCA), but warranting appropriate management if disturbed, as described, in the DNREC-approved CMMP. DNREC-RS also advises continued awareness of spent munitions when accessing the down-range areas of the Site.
