Delaware adopts final cleanup plan for Greenville Station site in Wilmington
Delaware’s environmental agency has adopted a final cleanup plan for the former Greenville Station property, a roughly 0.4-acre commercial site in Wilmington. The Delaware Department of Natural Resources and Environmental Control published the final remedial action plan on July 15, 2026.
The plan will shape how the property can be used or redeveloped. It requires ongoing contamination-management and environmental-stewardship measures, while an environmental covenant will place restrictions on the land and certain activities at the site.
Restrictions on future use
Under the plan, the property will be limited to non-residential use. The covenant will also restrict groundwater withdrawal and disturbance of the building slab, and it will require evaluation for vapor intrusion concerns.
The site contains a one-story commercial building divided into five tenant spaces. It operated as a gas station from at least 1964 through 1981. The final plan does not provide a contamination level in the approved source material, and its adoption should not be described as proof that all cleanup work has been completed.
Two management documents are required: a Contaminated Materials Management Plan and a Long-Term Stewardship Plan. Together, those requirements establish procedures for handling contaminated material and maintaining environmental controls over time. The approved notice does not identify a separate completion deadline for those measures.
Final action followed proposed plan
DNREC said it received no public comments or questions on the proposed plan before adopting the final version. That distinction matters: the July 15 notice records final agency action, while the public-comment statement describes the earlier proposed-plan process.
The property’s name creates an important geographic distinction for readers. Although it is identified as the Greenville Station site, the official notice places it in Wilmington, Delaware. It is not inside the census-designated Greenville community, so the plan should not be presented as a cleanup action within Greenville itself or as evidence that Greenville residents are directly affected.
A New Castle County agenda-center result dated July 23, 2026, showed public-hearing activity in August, but the available result did not establish a specific development or decision inside Greenville, Delaware. The approved information therefore supports reporting on DNREC’s final plan for the Wilmington property, not on a separate project in the Greenville community.
For the former commercial site, the practical effect is a framework for future property use and long-term environmental oversight. Groundwater withdrawal, slab disturbance and vapor concerns will remain subject to the restrictions and evaluation requirements in the final plan.
