ENB Region 8 Completed Applications 08/24/2005

Combined sewers convey both sewage and stormwater. During dry weather the sewers discharge to the local wastewater treatment plant where the effluent is treated to remove pollutants before discharge to the receiving water. During rain events, when storm water enters the sewers, the capacity of the sewer system to convey the combined effluent to the treatment plant is often exceeded and the effluent will discharge directly to the receiving water.

Since CSOs contain mixtures of domestic sewage, storm water runoff, and sometimes, industrial wastewater, they may contain high levels of suspended solids, toxic chemicals, floatable materials and other pollutants that can cause exceedances of water quality standards and use impairments. Such exceedances may pose risks to human and aquatic health and may impair the use and enjoyment of the Nation’s waterbodies.

This is a Department initiated modification to implement a department initiative to ensure compliance with the Clean Water Act.  On April 19, 1994, the United States Environmental Protection Agency (EPA) officially noticed  the Combined Sewer Overflow (CSO) Control Policy (Policy) to establish a consistent national approach for controlling discharges from all CSOs to the waters of the United States.  The Policy provides guidance to permittees and National Pollutant Discharge Elimination System (NPDES) permitting authorities on the implementation of both the technology-based controls, called the Nine Minimum Controls (NMCs), and development and implementation of water quality-based requirements, i.e., a Long Term Control Plan (LTCP).

In the Policy, EPA required that NPDES and SPDES permits would be modified to include the CSO requirements.  EPA also set a goal for municipalities to implement the NMCs by January 1, 1997 and develop a LTCP two years later.  As the NPDES permitting authority for New York State, the DEC has entered into an agreement with EPA to modify all remaining CSO SPDES permits in New York State in order to be in compliance with the Clean Water Act.

DEC has developed 15 CSO Best Management Practices (BMPs), in accordance with the CSO Control Policy and State regulations, that embody the NMCs.  Currently, the existing permit has only eight of the applicable BMPs.  All permittees will have these requirements included in their SPDES permit.

Long Term Control Planning is an additional control measure that: integrates the BMPs into the overall plan; evaluates the impact of CSO discharges on receiving water quality; evaluates and identifies control alternatives to address water quality use and standard impacts; and proposes implementation schedules of the chosen controls.

Therefore, the SPDES Permit for the Chemung County Elmira Sewer District STP has been modified accordingly to incorporate the 15 CSO BMPs and the LTCP requirements.

The Department has received an application for the modification of the above referenced solid waste management permit for the Phase III expansion of the Ontario County Landfill located at 3555 Post Farm Road.  This modification is proposed as bedrock was encountered at a higher elevation than previously mapped.  The modifications include raising the landfill subgrade in most locations to maintain the required 10 foot separation distance from the bedrock, excavation and replacement of weathered shale with 10 feet of compacted common fill in some locations, revision of cell design to allow leachate removal on the east and west sides of the landfill, abandonment of the existing leachate lagoon and replacement with above ground leachate storage tanks on the north side of the site and removal of a berm within the expansion footprint expanding the excavation limits by 4.04 acres in a previously disturbed area.  The Department has made a tentative determination to approve this application.  As a tentative determination, the Department is seeking public comments prior to making a final decision on permit issuance.

The SPDES Permit for the Village of Medina has been modified to incorporate the 15 CSO BMPs and the LTCP requirements.

The applicant proposes to install 300 lineal feet of stacked stone revetment along an eroded length of Taughannock Creek, P 296-98, located on his property at 5215 Buck Hill Rd. North in the town of Hector, Schuyler County.  

The application and file are available for review at the Region 8 located at 6274 East Avon-Lima Rd. in Avon.

The applicant proposes to to install a 4 inch waste transfer line running from a hog producing facility near Galen Road  to an existing manure storage lagoon.  The line will run about 2100 feet eastward to Drury Road, then north approximately 2400 feet along the east side of Drury Road, then east about 1300 feet to the existing manure storage facility.  The  project will involve approximately 880 feet of pipeline installation through Freshwater Wetland WO-36 (Class 2) and its corresponding 100-foot adjacent area.  The application and file are available for review at the Region 8 office located at 6274 East Avon - Lima Rd., Avon.
