285.27 Performance and emission standards.
(1)Standards of performance for new stationary sources.
(a)Similar to federal standard. If a standard of performance for new stationary sources is promulgated under section 111 of the federal clean air act, the department shall promulgate by rule a similar emission standard, including administrative requirements that are consistent with the federal administrative requirements, but this standard may not be more restrictive in terms of emission limitations than the federal standard except as provided under sub.
(4).
(b)Standard to protect public health or welfare. If a standard of performance for any air contaminant for new stationary sources is not promulgated under section 111 of the federal clean air act, the department may promulgate an emission standard of performance for new stationary sources if the department finds the standard is needed to provide adequate protection for public health or welfare.
(c)Restrictive standard. The department may impose a more restrictive emission standard of performance for a new stationary source than the standard promulgated under par.
(a)or
(b)on a case-by-case basis if a more restrictive emission standard is needed to meet the applicable lowest achievable emission rate under s. 285.63
(b)or to install the best available control technology under s. 285.63
(a).
(2)Emission standards for hazardous air contaminants.
(a)Similar to federal standard. If an emission standard for a hazardous air contaminant is promulgated under section 112 of the federal clean air act, the department shall promulgate by rule a similar standard, including administrative requirements that are consistent with the federal administrative requirements, but this standard may not be more restrictive in terms of emission limitations than the federal standard except as provided under sub.
(4).
(b)Standard to protect public health or welfare. If an emission standard for a hazardous air contaminant is not promulgated under section 112 of the federal clean air act, the department may promulgate an emission standard for the hazardous air contaminant if the department finds the standard is needed to provide adequate protection for public health or welfare. The department may not make this finding for a hazardous air contaminant unless the finding is supported with written documentation that includes all of the following:
1. A public health risk assessment that characterizes the types of stationary sources in this state that are known to emit the hazardous air contaminant and the population groups that are potentially at risk from the emissions.
2. An analysis showing that members of population groups are subjected to levels of the hazardous air contaminant that are above recognized environmental health standards or will be subjected to those levels if the department fails to promulgate the proposed emission standard for the hazardous air contaminant.
3. An evaluation of options for managing the risks caused by the hazardous air contaminant considering risks, costs, economic impacts, feasibility, energy, safety, and other relevant factors, and a finding that the chosen compliance alternative reduces risks in the most cost-effective manner practicable.
