Nation's First Acid Rain Law

In 1984, NY passed the nation's first law to reduce "acid rain" from in-state air pollution sources. DEC is adding soda ash to neutralize acid rain.


DEC also initiated the State Acid Deposition Control Act, a policy to control acid rain in areas susceptible to the impacts of acid rain, including the Adirondacks, Catskills, and the Hudson Highlands. Here, DEC staff are adding soda ash to Bone Pond to neutralize the pH. #DEC50
