Negative Declaration

Nassau County - The Nassau County Department of Public Works (NCDPW), as lead agency, has determined that the proposed Village of Hempstead Sanitary Sewage Flow Diversion / Baldwin SSO Project will not have a significant adverse environmental impact. Nassau County is currently moving into the preliminary design phase of the Village of Hempstead Sanitary Sewage Flow Diversion Project. As a precursor to preliminary design, Nassau County has completed a Technical Design Report (TDR) to identify project scope and alternatives, necessary permitting and approvals, cost estimates and scheduling. At this time, Nassau County is applying to the New York State Environmental Facilities Corporation (NYS EFC) for funding under the Clean Water State Revolving Fund Storm Mitigation Loan Program (SMLP). The County of Nassau will be designing and constructing a new Flow Diversion Pump Station and an associated Force Main Piping System within the Village of Hempstead, New York. The new Flow Diversion Pump Station and Force Main Piping System will transfer a portion of the Village of Hempstead's wastewater eastward to a connection point in the Nassau County's Sewer Collection District No.3 in North Merrick, New York and ultimately for proper treatment and discharge from Nassau County's Cedar Creek Water Pollution Control Plant (WPCP) located in Wantagh, New York. The new pump station will be located on property owned by the Village of Hempstead (i.e., Weekes Park), which currently houses the Village of Hempstead owned Weekes Park Pump Station. A three mile long force main will be located within both Village of Hempstead and Nassau County roads, with a small portion passing underneath a State Parkway (i.e., Meadowbrook State Parkway). Reducing sewage flow within the Baldwin sewer system upstream of the Barnes Avenue location will likely reduce sanitary sewer overflows (SSO) in Baldwin. Traditional solutions have included the reduction of infiltration and inflow (1 and 1) and water conservation. While these methods have merit, the actual reduction of flow is often far less than anticipated with respect the cost of the investigation and remediation. As a result, flow diversion is recommended to provide for a more permanent reduction in flow, which will likely reduce the potential for SSO's. The project is located in the Village of Hempstead and the Hamlet of East Meadow, New York.
