Today's rule establishes our ``generic MACT standards'' program for setting national emission standards for hazardous air pollutants (NESHAP) under section 112 of the Clean Air Act (Act) for certain small source categories consisting of five or fewer major sources. As part of this generic MACT program, we are establishing an alternative methodology for making maximum achievable control technology (MACT) determinations for appropriate small categories by referring to previous MACT standards that have been promulgated for similar sources in other categories. The basic purposes of the generic MACT program are to use public and private sector resources efficiently, and to promote regulatory consistency and predictability in MACT standards development. Today's consolidated rulemaking package includes promulgated MACT standards that have been developed within the generic MACT framework for four specific source categories that are included on our list of categories for which NESHAP are required: acetal resins (AR) production, acrylic and modacrylic fiber (AMF) production, hydrogen fluoride (HF) production, and polycarbonate(s) (PC) production. In this consolidated rulemaking package, we are also promulgating general control requirements for certain types of emission points for hazardous air pollutants (HAP), which will then be referenced, as appropriate, in MACT requirements for individual source categories. These general control requirements are set forth in new promulgated subparts and are applicable to storage vessels containing organic materials, process vents emitting organic vapors, and leaks from equipment components. In addition, we are promulgating a separate subpart of requirements for closed vent systems, control devices, recovery devices and routing emissions to fuel gas systems or a process. We have withdrawn the proposed process wastewater provisions from the promulgated rule. In a supplemental notice of proposed rulemaking (SNPR) published elsewhere in today's Federal Register, we reopen the comment period (for 30 days) specifically to request additional comment on amendments to the proposed standards for process wastewater provisions for the AR, AMF, and PC production source categories. We plan to take final action regarding the amendments to the proposed provisions for process wastewater streams by November 15, 1999 (the revised date set forth in a proposed consent decree). 64 FR 34854 https://www.govinfo.gov/app/details/FR-1999-06-29/99-13164 99-13164 fr29jn99-13 RIN 2060-AG91 RIN 2060-AF06 RIN 2060-AG94 RIN 2060-AF09 RIN 2060-AE36 6560-50-P AD-FRL-6346-9 https://www.govinfo.gov/app/details/FR-1999-06-29/99-13164 https://www.govinfo.gov/content/pkg/FR-1999-06-29/html/99-13164.htm https://www.govinfo.gov/content/pkg/FR-1999-06-29/pdf/99-13164.pdf 96 p. 34854 34949 64 FR 34854 Title 40 Part 63 40 CFR Part 63 RIN 2060-AG91 RIN 2060-AF06 RIN 2060-AG94 RIN 2060-AF09 RIN 2060-AE36 National Emission Standards for Hazardous Air Pollutants: Generic Maximum Achievable Control Technology (Generic MACT); Federal Register Vol. 64, Issue RULE 99-13164 II ENVIRONMENTAL PROTECTION AGENCY 1999-06-29 AD-FRL-6346-9 6560-50-P 99-13164 Final rule.
