The Environmental Protection Agency (EPA) is finalizing its action to codify into the Code of Federal Regulations (CFR) the delegation of authority to implement and enforce the Federal Plan Requirements for Sewage Sludge Incineration Units Constructed on or before October 14, 2010 (SSI Federal Plan) to the New Hampshire Department of Environmental Services (NH DES). The SSI Federal Plan addresses the implementation and enforcement of the emission guidelines applicable to existing SSI units located in areas not covered by an approved and currently effective state plan. The SSI Federal Plan imposes emission limits and other control requirements for existing affected SSI facilities which will reduce designated pollutants. This action is being taken under the Clean Air Act (CAA).
