Ash Monofill Landfills

Ash Monofill Landfills in New York State

As of January 2016, there are two ash monofill landfills operating in New York State, both of which are located on Long Island. Except in Nassau and Suffolk counties, the minimum liner required for an ash monofill landfill is a single composite liner with a leachate collection and removal system.
