Greetings All,
We are writing with an update on remediation activities at the 250 Water Street site.
Installation of perimeter support of excavation (SOE) along Pearl and Beekman Streets will continue this week to support ongoing excavation and site dewatering. SOE activities along Pearl and Beekman Streets include installation of the perimeter soil mix cut-off wall and installation and testing of tie-backs.
Excavation and off-site disposal of soil/fill is expected to continue in the Phase 2 area. Confirmation endpoint soil samples will be collected at Track 2 cleanup levels. Archaeological monitoring will take place when excavation occurs 8 feet below grade surface (bgs). Odor/vapor suppressing foam will be applied proactively in areas with previously identified nuisance odors.
Work is scheduled to take place Monday through Wednesday between 7:00am to 6:00pm. Limited work may also take place on Friday during these hours and Saturday from 9:00am to 5:00pm. Deliveries of equipment and materials are planned to occur as needed.
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.
