REMINDER – this weekend
Foundation and associated remediation work on the 250 Water Street site is continuing this week and will take place on Saturday, May 21, 2022, with work planned from 8am – 4pm. The balance of the work will resume on Monday, May 23.
We understand concerns regarding air quality have arisen due to brief periods of air monitoring data transmission malfunctions this past week. Langan moved quickly to address the issue and was able to recover all the recorded mercury vapor data, which is saved internally on all mercury vapor units. The data from periods of transmission gaps showed readings of 0.0 ug/m3, indicating that the remediation activities remained safe for the public and onsite workers. This data will be included in revised daily field reports and shared with the New York State Department of Environmental Conservation (NYSDEC) and the community consultants and will be available to the public on the BCP website. Protocols are in place to prevent and backup telemetry system transmission malfunctions going forward.
We would also like to clarify that no pile driving has taken place during this phase of work. Four piles have been drilled (also referred to as augered) as part of the initial foundation and that work has been completed. Installation of steel sheet piling was completed today. The sheet piles were vibrated into the ground with a vibratory hammer, a process that produces less noise than impact pile driving.
Remediation work will continue to be performed in accordance with the Remedial Action Work Plan under the New York State Brownfield Cleanup Program, overseen by the NYSDEC and the Department of Health (NYSDOH). Daily reports will be prepared and submitted to the NYSDEC on the day following each workday, and the daily reports, including daily air monitoring results, will be uploaded to the BCP website.
We will continue to regularly update community stakeholders as work is completed.

Brownfield Cleanup Program
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
