The Department invites public comment on a proposal to clean-up IRP Site 2 (Soil) of the Delaware Air National Guard Site located in New Castle. The Site is an active military base, and the removal of underground storage tanks and petroleum contaminated soil, along with a bioventing system was previously required to clean-up contamination at IRP Site 2. The Amended Proposed Plan reflects the addition of land use controls to the remedy.

Details of the Amended Proposed Plan are available online at:
