{"abstract":"The EPA is proposing to change the Agency's current procedures for delegating to State, local, territorial, and Indian tribes as defined in 40 CFR 71.2 or agencies (i.e., S/L's) the authority to implement and enforce Federal air toxics emissions standards and other requirements. Specifically, these regulatory amendments propose to revise procedures and criteria for approving S/L rules, programs, or other requirements that would substitute for Federal emissions standards or other requirements for hazardous air pollutants (HAP) established under section 112 of the Clean Air Act (Act). Section 112(l) of the Act authorizes us to approve S/L programs when S/L alternative requirements are demonstrated to be no less stringent than the rules we promulgate. These amendments would increase the flexibility of our existing regulations in 40 CFR part 63, subpart E that implement section 112(l) of the Act. They would provide a greater number of approval processes from which S/L's can choose, increase the flexibility S/L's have to demonstrate equivalency for their alternative requirements, and provide options that will expedite the approval process. In addition, the policy guidance in this notice clarifies what S/L's must or can do to obtain delegated authority under subpart E, including how they can demonstrate equivalency for alternatives to Federal requirements. These changes are in response to requests we received from State and local air pollution control agencies to reconsider our existing regulations in light of implementation difficulties they have experienced or anticipated. We believe this effort is consistent with the President's regulatory ``reinvention'' initiative, and it will result in less burden to S/L's, regulated industries, and the Federal Government without sacrificing the emissions reduction and enforcement goals of the Act. These amendments reduce the potential for redundant or conflicting air regulations on industry while they accommodate a wider variety of S/L program needs. This rulemaking addresses requirements that apply to S/L's, should they choose to obtain delegation or program approval under section 112(l). (Obtaining delegation under section 112(l) is voluntary). This rulemaking does not include any requirements that apply directly to stationary sources of HAP or small businesses that emit HAP.","action":"Proposed amendments; notice of public hearing.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/1999/01/12/99-8.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"63","title":40}],"citation":"64 FR 1880","comment_url":null,"comments_close_on":"1999-03-15","correction_of":null,"corrections":[],"dates":"Comments.
