National Emission Standards for Hazardous Air Pollutants for Source Categories; Wool Fiberglass Manufacturing

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for new and existing sources in wool fiberglass manufacturing facilities. This action also adds Method 316 and Method 318 for the measurement of formaldehyde from wool fiberglass manufacturing lines to appendix A of part 63. The hazardous air pollutants (HAPs) emitted by the facilities covered by this rule include compounds of three metals (arsenic, chromium, lead) and three organic HAPs (formaldehyde, phenol, and methanol). Exposure to these HAPs can cause reversible or irreversible health effects including carcinogenic, respiratory, nervous system, developmental, reproductive, and/or dermal health effects. The EPA estimates the final rule will reduce nationwide emissions of HAPs from these facilities by 530 megagrams per year (Mg/yr) (580 tons per year [ton/yr]), an approximate 30 percent reduction from the current level of emissions. In addition, the rule will achieve an estimated 760 Mg/yr (840 ton/yr) of particulate matter (PM) reductions. These standards implement section 112(d) of the Clean Air Act (CAA) and are based on the Administrator's determination that wool fiberglass manufacturing facilities may reasonably be anticipated to emit several of the 188 HAPs listed in section 112(b) of the CAA from the various process operations found within the industry. The final rule will provide protection to the public by requiring all wool fiberglass plants that are major sources to meet emission standards reflecting the application of the maximum achievable control technology (MACT). In compliance with the Paperwork Reduction Act (PRA), this action also amends the table that lists the Office of Management and Budget (OMB) control numbers issued under the PRA for this rule. A supplement to the proposed rule was proposed in the Federal Register on February 12, 1999 (64 FR 7149). The EPA will give careful consideration to all comments on the supplemental proposal and will amend thi
