{"abstract":"General Provisions (Subpart A). On March 16, 1994, the EPA promulgated General Provisions for national emission standards for hazardous air pollutants (NESHAP) and other regulatory requirements that are established under section 112 of the Clean Air Act as amended in 1990 (CAA or Act) (59 FR 12408). In today's action, we are proposing amendments to the General Provisions that would revise and clarify several of the current provisions. We are proposing these amendments, in part, as a result of decisions reached in settlement negotiations conducted between petitioners, who filed for review of the General Provisions, and the EPA. The proposed amendments also reflect internal EPA discussions on issues regarding implementation of the General Provisions. Section 112(j) Provisions (Subpart B). In addition, in today's action, we are proposing amendments to rules that establish equivalent emission limitations by permit under section 112(j) of the Act. The \"section 112(j)\" rule establishes requirements and procedures for owners or operators of major sources of hazardous air pollutants (HAP), and permitting authorities, to comply with section 112(j). The section 112(j) rule was promulgated on May 20, 1994 (59 FR 26429). These proposed amendments have been developed in response to settlement negotiations conducted between petitioners, who filed for review of the section 112(j) rule, and the EPA. The proposed amendments also reflect internal EPA discussions regarding implementation of the section 112(j) rule.","action":"Proposed amendments.","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/2001/03/23/01-5251.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"66 FR 16318","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Comments.
