The Department invites public comment on a proposal to clean-up Operable Unit 2 (OU-2) of 516 North King Street & Alico Road (DE-0371) located at 516 North King Street in Wilmington. The ±0.85-acre Site was administratively divided into two Operable Units (OUs) in April 2023 as a new area was amended to the Site after the majority of the Brownfield investigation activities had been completed. The ±0.13-acres OU-2 consists of concrete paved sidewalk areas and maintained landscaped areas. The nearest intersection to the Site is North King Street and Alico Road. OU-2 includes concrete-paved sidewalk and landscaped areas.
OU-2 will be subject to the following key remedial actions: the submittal of a Remedial Action Work Plan which specifies the methods to be used to remediate OU-2 including the design and installation of a passive vapor mitigation system of the existing and proposed new building; development and compliance with the Contaminated Materials Management Plan (CMMP); the recording of an Environmental Covenant restricting use to non-residential type and compliance with the Contaminated Materials Management Plan (CMMP) as well as the Long-Term Stewardship (LTS) Plan; completion of a CMMP and LTS Plan; abandonment and closure of on-site soil gas sampling points once no longer in use; and the submittal of a Remedial Action Completion Report.
Details of the Proposed Plan are available online at: den.dnrec.delaware.gov/
The comment period ends on November 27, 2023. For additional information, please contact Morgan McGee-Solomon, Project Manager at (302) 395-2600 or via email at RS_Public_Comments@delaware.gov.
