The Department invites public comment on a proposal to clean-up 320 & 340 S Market St. Site (DE-1761) located at 320 & 340 S Market St. in Wilmington. The Site historically contained storage buildings which included an “anhydrous plant” building, a coal shed, and “aqua ammonia” tanks. The site also contained two filling stations with several USTs, an oil storage building, and several ASTs. Finally, a car wash building operated on the site.
The site will be required to implement and maintain a cap. The site will also be subject to an environmental covenant which will place limitations on groundwater withdrawal and land disturbing activities. It will also require compliance with a Contaminated Materials Management Plan and Long Term Stewardship Plan.
The comment period ends on October 18, 2021. For additional information, please contact John Costa, Project Manager at (302) 395-2600 or via email at RS_Public_Comments@delaware.gov.
