Treatment Plant Upgrades in Westchester

Westchester County has agreed to begin work on nitrogen removal at its four Long Island Sound sewage plants, mandated as part of the Sound cleanup. County officials agreed reluctantly. They apparently thought a nitrogen-trading program, like Connecticut’s, would be more cost-effective, and wanted to buy nitrogen credits from New York City.

State officials, though, said it wouldn't work because the state was already suing the city for having missed treatment plant upgrade deadlines. I think, though, that there is no legal mechanism in New York for trading nitrogen credits, as there is in Connecticut.
