Long Island Landfills

Long Island Landfills in New York State

The Long Island Landfill Law, ECL 27-0704, placed additional requirements and restrictions on Long Island Landfills. This refers to all landfills located in Nassau and Suffolk Counties. As of January 2016, there were 6 landfills operating on Long Island, 2 of which were ash monofills.

Each new landfill or expansion located outside the deep flow recharge area, can accept material that is the product of resource recovery, incineration, or composting and downtime waste, and untreatable waste. The minimum liner requirement for landfills outside the deep flow recharge area is a double composite liner system with a primary and secondary leachate collection and removal system.

Each new landfill or expansion located within the deep flow recharge area, can only accept clean fill. The minimum liner requirement for clean fill landfills inside the deep flow recharge area is a double liner system consisting of an upper geomembrane and a lower composite liner system with a primary and a secondary leachate collection and removal system. Clean fill landfills outside the deep flow recharge area must have a single composite liner system with a provision for leachate collection and removal.
