Upgrades to the Tallman Island Wastewater Treatment Plant in College Point will Reduce Nitrogen Discharges and Increase Dissolved Oxygen Levels in the Surrounding Waterways

Over the Last Decade DEP Has Invested More Than $1.5 Billion to Reduce Nitrogen Discharges from the City’s Wastewater Treatment Plants

New York City Department of Environmental Protection (DEP) Commissioner Emily Lloyd today announced that DEP has completed a $230 million upgrade to the Tallman Island Wastewater Treatment Plant that will reduce the amount of nitrogen discharged from the plant into the Upper East River and Long Island Sound by more than 3,500 pounds per day, or nearly 1.3 million pounds each year. The upgrade will allow the plant to convert the organic nitrogen present in wastewater into inert nitrogen gas that can then be released harmlessly into the atmosphere before the treated water is released into the surrounding waterways. High levels of nitrogen can degrade the overall ecology of a waterway by reducing levels of dissolved oxygen and promoting excessive algae growth, especially in warm weather months. As part of an agreement with the New York State Department of Environmental Conservation (DEC), DEP has committed to reduce nitrogen discharges from its four wastewater treatment plants locat ed along the Upper East River by nearly 60 percent by 2017.
