A formally closed landfill is one that is capped or removed, by a design plan that receives construction approval upon satisfactory review by the Department. Financial assistance is available to municipalities to help with the expense of closing unlined landfills through the State Revolving Loan Fund and the State Landfill Closure Grant Program . With the advancement of technology for managing waste disposal has come the development of lined landfills. They are also monitored through a leak detection system including a network of groundwater monitoring wells installed under the terms of a Groundwater Management Permit. The facilities are also monitored for compliance with air pollution control regulations.
Closure generally entails preparation of a plan for approval by the agency.
Incinerators In New Hampshire, there are generally two types of incinerators, those that simply reduce the volume of waste into ash, and those that also generate energy when the waste is burned. Both types of facilities are closed under the terms of formal closure plans filed with the Department for approval, and work is done to be certain all environment and health issues are properly addressed at the time of closure. State grant monies are available for the closure of eighteen specific municipally owned incinerator facilities. Closure also includes the cleaning of any facilities that housed the processing equipment.
