Permit(s) Applied for:

Article 17 Titles 7 & 8 Industrial SPDES - Surface Discharge

Project is Located:

BROOKLYN, KINGS COUNTY

Project Description:

The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve a proposed withdrawal and discharge of up to 2,880,000 gallons per day of treated groundwater into Upper New York Bay, a Class 1 waterbody. Dewatering is required for the construction of a substation which requires piles/pile caps for construction and installation of a new conduit cable. The work will be in two distinct work areas (Part 1 and Part 2) so there will be two treatment systems and discharge locations.

Part 1 dewatering will be conducted through sump pumps with a maximum discharge rate of 1,440,000 gallons per day (GPD) and up to six (6) pits will be dewatered at any time for a total of up to 1,440,000 GPD. Tri-State Groundwater (TSGS) will install 6" Sch 40 PVC discharge piping to connect the dewatering system to the discharge location. The point of discharge will be a combined sewer overflow via an existing connection that leads to outfall OH-022 to Gowanus Bay.

Part 2 dewatering will be conducted through a system of ten (10) 12-inch deep wells to be installed at a depth of forty (40) feet. Sumps will be utilized as needed. The maximum discharge rate will be 1,440,000 GPD. TSGS will install 6-inch Sch 40 PVC discharge piping to connect the dewatering system to the discharge location. The discharge point will be an existing sewer overflow pipe on 2^nd Ave between 28th and 29th Streets. The sewer leads to Outfall OH-025 to Gowanus Bay.
