The Department has adopted a plan regarding the clean-up of Operable Units 1 and 2 of the Sixteenth Street Quarry Site located in Wilmington. The Site, once used as a quarry since the late 1800s, required an Environmental Covenant for OU-1 and OU-2; Contaminated Materials Management Plan for OU-1 and OU-2; and a Long Term Stewardship Plan for OU-1 for maintenance of the existing cap; and any filling will be conducted in accordance with the Soil Reuse Policy. 

DNREC issued public notice of the Proposed Plan for OU-1 and OU-2 of the Sixteenth Street Quarry Site on January 12, 2020.  There were no comments or questions from the public regarding the Proposed Plan.  Details of the Final Plan are available at the office of DNREC-RS (391 Lukens Drive, New Castle, DE, 19720) or online at:
