GOWANUS —The NY State Department of Environmental Conversation will begin supervising a cleanup this month of 380 4th Avenue, brownfield site in Gowanus that is adjacent to the U-Haul storage center. The applicant for a development at that site, 380 4th Avenue Owner, LLC, will perform the cleanup of contamination with several components, including: excavation and off-site disposal of contaminated soil to a minimum depth of 15 feet below ground surface and hotspot areas; collection and analysis of confirmation soil samples to evaluate the remedy’s effectiveness and importing clean fill that meets the established Soil Cleanup Objectives for use as backfill.
A site-specific Health and Safety Plan (HASP) and a Community Air Monitoring Plan (CAMP) will be implemented during remediation activities, establishing procedures — such as required air monitoring as well as dust and odor suppression measures —to protect on-site workers and residents.
