Greetings All,
We are writing with an update on remediation activities at the 250 Water Street site.
Installation of support of excavation (SOE) will continue along the perimeter of the site to support ongoing excavation in the Phase 2 area (towards Beekman Street) and future site-wide dewatering. SOE activities in the Phase 1 area (towards Peck Slip) will consist of installation of a concrete guide wall along Water Street and installation of soil mix columns along Peck Slip and Pearl Street. SOE activities in the Phase 2 area will consist of drilling for tiebacks along Beekman Street.
Excavation is expected to continue to a depth of about 8 feet below grade surface (bgs) in the Phase 2 area. Archaeological monitoring will take place when excavation occurs below 8 feet bgs.
The suspected underground storage tank (UST) in the Beekman/Water Street corner of the site is expected to be removed, cleaned, and disposed of off-site along with an additional UST identified this past week. Based on previous investigation, nuisance odors are not anticipated in the area surrounding the suspected UST; however, odor/vapor suppressing foam will be applied as needed during removal and decommissioning of the tanks. Odor/vapor suppressing foam will also be applied proactively in areas with previously identified nuisance odors.
Work is scheduled to take place between 7:00am to 6:00pm. Deliveries of equipment and materials are planned to occur daily during these hours.
Remediation work is being performed under the Remedial Action Work Plan (RAWP), as approved by the NYS Department of Environmental Conversation (DEC) and NYS Department of Health (DOH) under the Brownfield Cleanup Program (BCP). The Community Air Monitoring Plan (CAMP) and Construction Health and Safety Plan (CHASP) will be implemented during the remediation as required.
Additional information on the BCP and 250 Water Street cleanup is available on the project website https://250bcp.com/.
We will continue to update community stakeholders as work proceeds.

More than 100 New York City sites have been successfully remediated under New York State’s Brownfield Cleanup Program (BCP), a program which encourages private sector cleanups and redevelopment of urban brownfields with regulatory oversight by NYS Department of Environmental Conservation and Department of Health. The BCP emphasizes transparency and requires robust citizen participation with numerous opportunities for public review and input into environmental investigation, remediation planning and implementation
