Division of Waste and Hazardous Substances

Comments Due: May 22, 2023

The Department invites public comments on a proposal to clean-up 609 Philadelphia Pike Site (DE-1795) located at 609 Philadelphia Pike in Wilmington. From the early 1960s until the mid-1980s, the Site was a gasoline and service station with underground storage tanks and fuel dispensers. Historic Site operations likely resulted in petroleum releases which have impacted the groundwater. The commercial building, attached additions, and single detached garage were demolished in September 2022.

609 Philadelphia Pike Site will be subject to the following remedial actions including: removal or closure of underground storage tanks and any identified hydraulic lifts; disposal of petroleum impacted soils; development and compliance with a Contaminated Materials Management Plan (CMMP); and recording of an Environmental Covenant restricting well installation and groundwater withdrawal.

Details of the Proposed Plan are available online at:
