Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and Five-Year Review

Environmental Protection Agency

Abstract

The U.S. Environmental Protection Agency (EPA) is finalizing new source performance standards (NSPS) and emission guidelines (EG) for the large municipal waste combustion (MWC) source category. This final rule responds to a voluntary remand of the preceding rule for this source category and announces the results of the non-discretionary review at five-year intervals required by Clean Air Act (CAA) section 129(a)(5), fulfilling the requirements of a consent decree for the source category. The final rule revises the remanded emission limits for cadmium, lead, particulate matter, polychlorinated dibenzodioxins and dibenzofurans, mercury, hydrogen chloride, and sulfur dioxide for all sources subject to the NSPS and EG and the remanded emission limits for nitrogen oxides and carbon monoxide for some sources subject to the EG and all sources subject to the NSPS. This final rule also removes certain startup, shutdown, and malfunction (SSM) exclusions and exemptions. In addition, the EPA is taking this opportunity to streamline regulatory language; revise recordkeeping and reporting requirements; establish electronic notification; reestablish new and existing source applicability dates; eliminate title V requirements for air curtain incinerators that burn only wood waste, yard waste, and clean lumber; close a 2007 proposed reconsideration action; and make certain typographical and technical corrections and clarifications. The EPA estimates this final rule will result in 3,269 tpy reduction in regulated pollutants from existing sources through implementation of the final emission limits.
