The Department has adopted an amended plan regarding the clean-up of Operable Unit 4 of the Chrysler Newark Assembly Plant Site located in Newark. Unit 4 (OU-4) of the Chrysler Newark Assembly Plant Site (DE-0105) located in Newark. The approximately 272-acre Site was the former location of a vehicle assembly plant and is currently the location of the University of Delaware’s Science, Technology, and Advanced Research (STAR) Campus. This Amended Final Plan of Remedial Action specifically addresses a 24.6-acre portion of the Site referred to as OU-4. OU-4 was divided into two sections, OU-4A and OU-4B, in consideration of development plans.

OU-4A is not subject to any remedial actions for soil. In addition to remedial actions previously implemented in accordance with the original Final Plan of Remedial Action, additional requirements for OU-4B of the Site include maintenance of capping atop soils within two areas of concern, restriction to non-residential use, and continued compliance with the site-specific Contaminated Materials Management Plan and Long-Term Stewardship Plan, which includes groundwater monitoring. All of OU-4 is subject to a restriction on groundwater use.

DNREC issued a public notice of the Amended Proposed Plan for Operable Unit 4 of the Chrysler Newark Assembly Plant Site on May 4, 2022. There were no comments or questions from the public regarding the Amended Proposed Plan. Details of the Amended Final Plan are available online at: den.dnrec.delaware.gov
