Albany Pool CSO LTCP

Six Capital Region communities known as the "Albany Pool"-the Cities of Albany, Troy, Rensselaer, Cohoes and Watervliet, and the Village of Green Island-have developed a Long-Term Control Plan (LTCP) under a consent order with DEC. The plan will address the combined sewer overflow (CSOs) discharges into the Hudson River and improve water quality. These six communities, along with the Albany County and Rensselaer County sewer districts will implement the plan.

Background

The communities within the Albany Pool area of the Hudson River have combined sewer systems (CSS). These systems are designed to collect storm runoff, domestic sewage and industrial wastewater in the same pipe and bring it to the treatment plant. During rain or snowmelt events, the capacity of the system may be exceeded and the excess water is discharged to waterbodies (rivers, streams, estuaries, and coastal waters). This type of system is common in older cities across New York.

The discharge locations are called combined sewer overflow (CSO) outfalls. The Albany Pool area has 92 CSO outfalls. The Combined Sewer Overflow (CSO) Outfalls Google Map provides the location and general facility information for CSOs in NYS, including the Albany Pool.

How will the LTCP help the Hudson River?

The LTCP is a phased approach to control CSOs. When the LTCP is fully implemented, Albany Pool communities and the two sewer districts will capture 85 percent of the annual CSO volume and treat it for bacteria and sewage-related floatable waste. This will improve the river's water quality and allow for recreational activities (swimming and fishing) to resume within hours instead of days after a typical rainstorm event.

The LTCP implements a strategy to maximize the use of green infrastructure practices for additional CSO reduction over time.

Key elements of the LTCP include:

  • Maximizing the flow of combined sewage from the Albany Pool communities to the Albany County and Rensselaer County wastewater treatment plants (WWTPs); pump stations upgrades; sewer system improvements; and sizing the new bacterial disinfection systems in the county treatment plants to accommodate and treat more stormwater-related volume.
  • Building and operating a new satellite treatment facility to disinfect CSO flow and control of sewage-related floatable waste at the largest CSO outfall in the system, located on Broadway by the U-Haul building in the City of Albany.
  • Implementing multiple projects to separate combined sewers (create separate lines for stormwater and sewage) to eliminate some existing CSOs.
  • Adding facilities to control the discharge of floatable waste at major CSO outfalls in the city of Cohoes and at the Corning Preserve in Albany.
  • Implementing a long-term green infrastructure (GI) strategy to further reduce CSO releases above the 85 percent capture and treatment level. The strategy will maximize the use of GI in the Albany Pool communities, which will reduce CSOs over time. GI practices help control stormwater at its source, remove pollutants, and reduce the amount of runoff and waste that ends up in sewer systems and local water bodies. Examples of GI practices are green roofs, pervious pavement and rain gardens

Long Term Control Plan

The Final Albany Pool CSO LTCP is comprised of two documents: Albany Pool CSO Long Term Control Plan (PDF, 4.8 MB), plus the 2013 Supplemental Documentation (PDF, 779 KB), collectively these documents make up the final Albany Pool CSO LTCP. The documents provide additional details of the key elements of the plan, descriptions of sampling locations and data, CSO monitoring data and model development, CSO control alternatives, and also includes a compliance schedule.

The projects will bring the Albany Pool and Rensselaer and Albany County sewer districts in compliance with NYS water quality standards and Clean Water Act requirements.

Other water quality improvements

Water quality improvements to the Hudson River already underway through other New York State consent orders and the State Pollution Discharge Elimination System (SPDES) permit program include:

  • Installing equipment in the Rensselaer County Sewer District to disinfect treated effluent. Seasonal disinfection will begin on May 1, 2014.
  • Addressing discharges in the Rensselaer County Sewer District and the cities of Troy and Rensselaer that can result in sewage spills during dry weather.
  • Completion of improvements at the East Greenbush WWTP and within its sewer system by December 31, 2014 to eliminate sewage overflows during wet weather.
  • Installing disinfection systems in the Albany County Sewer District for its treated effluent by 2014 and beginning seasonal effluent disinfection at its north and south plants in 2014.
