On March 21, 2011, the EPA promulgated national emission standards for the control of hazardous air pollutants from new and existing industrial, commercial, and institutional boilers and process heaters at major sources of hazardous air pollutants. On that same day, the EPA also published a notice announcing its intent to reconsider certain provisions of the final rule. The EPA subsequently issued a notice on May 18, 2011, to postpone the effective dates of the final rule until judicial review has been completed, or the agency finalizes its reconsideration of the standard, whichever is earlier. In the action to postpone the effective dates of the rule, the EPA also requested the public to submit data and information to assist the EPA in its reconsideration. Following these actions, the ...
On March 21, 2011, the EPA promulgated national emission standards for the control of hazardous air pollutants from two area source categories: industrial boilers, and commercial and institutional boilers. On that same date, the EPA announced that it was convening a proceeding for reconsideration of certain portions of those final emission standards. After promulgation, the Administrator received petitions for reconsideration of certain provisions in the final rule. In this action, the EPA is proposing for reconsideration specific elements and accepting public comment on those elements. We are not requesting comment on any other provisions of the final rule. In this action, the EPA is proposing a limited number of amendments to the final rule. In addition, the EPA is proposing amendment...
Throughout its forty-year history, the Environmental Protection Agency (EPA) has struggled with its statutory obligation to address the risks that hazardous air pollutants (HAPs) pose to nearby human populations. This has never been an especially pressing issue for EPA's leadership, because for most of this time public attention has focused on the more conventional "criteria" pollutants that cloud the skies of most American cities. Unlike the criteria pollutants, which come from "numerous or diverse mobile or stationary sources," HAPs are associated with particular industrial activities, like chemical plants and metal smelters, and they are typically more toxic to fewer people at much lower concentrations. Although EPA has established national ambient-air-quality standards for the crite...

On May 3, 2011, under authority of Clean Air Act (CAA) sections 111 and 112, the EPA proposed both national emission standards for hazardous air pollutants (NESHAP) from coal- and oil-fired electric utility steam generating units (EGUs) and standards of performance for fossil-fuel-fired electric utility, industrial-commercial- institutional, and small industrial-commercial-institutional steam generating units (76 FR 24976). After consideration of public comments, the EPA is finalizing these rules in this action. Pursuant to CAA section 111, the EPA is revising standards of performance in response to a voluntary remand of a final rule. Specifically, we are amending new source performance standards (NSPS) after analysis of the public comments we received. We are also finalizing several mi...
