Construction and Demolition (C&D) Debris Landfills

As of January 2016, there were 110 registered Land Clearing Debris Landfills and 12 regulated Construction and Demolition Debris Landfills. The registered land clearing debris landfills are required to be three acres or less and to have, at a minimum, a compacted soil final cover within 180 days of cessation of waste acceptance. The permitted C&D debis landfills greater than three acres are required, at a minimum, to have a single composite liner with a leachate collection and removal system. Permitted C&D debris landfills of three acres or less must have, at a minimum, a low-permeability compacted soil base.

Long Island Landfills

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.

Industrial/Commercial Waste Landfills

Industrial Waste Landfills are used for the disposal of industrial wastes such as coal ash and paper mill sludges. As of January 2016, there were 12 industrial/commercial landfills operating in New York State. The liner required for an industrial/commercial waste monofill landfill is a double composite liner with primary and secondary leachate collection and removal systems. Alternative liner system designs will be considered if the applicant demonstrates that the proposed alternative liner will prevent a negative impact on groundwater. Solid waste incinerator ash residue monofills except in Nassau and Suffolk counties and paper mill sludge monofills have a minimum liner requirement comprised of a single composite liner with a leachate collection and removal system.

Ash Monofill Landfills

Ash from the combustion of municipal solid waste is disposed of at these facilities. 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.

State assistance grants are available for eligible municipal landfill closure projects.
