Proposed Plan of Remedial Action for the Community Plaza New Castle OU-2 (DE-1567)


Division of Waste and Hazardous Substances
Start Date: October 30, 2019
End Date: November 19, 2019

The Department invites public comment on a proposal to clean up a portion of the Community Plaza New Castle Site Operable Unit 2 (OU-2) located in New Castle, Delaware.  The approximately 8.7-acre Site consists of two (2) tax parcels with two commercial buildings used as a shopping center. OU-2 addresses groundwater and soil gas.  OU-1 addressed soil in a previous Proposed Plan and Final Plan.  The groundwater contained metals, volatiles organic compounds, and semi-volatile organic compounds above DNREC groundwater standards.  Air samples did not show a risk to indoor air.   OU-2 requires an environmental covenant to prevent groundwater use without DNREC approval, a Contaminated Materials Management Plan (CMMP) to protect future construction workers from potential contamination and a long-term stewardship plan to monitor groundwater and indoor air to ensure that the remedies remain protective.  Details of the Proposed Plan are available at the office of DNREC-RS (391 Lukens Drive, New Castle, DE, 19720), or online at www.nav.dnrec.delaware.gov/DEN3/

The comment period ends on November 19, 2019.  For additional information, please contact Rick Galloway, Project Manager at (302)395-2600 or rick.galloway@delaware.gov.
