On June 29, 1999 (64 FR 34854), EPA promulgated a consolidated rulemaking that included standards for four specific source categories (i.e., acetal resins (AR), acrylic and modacrylic fiber (AMF), hydrogen fluoride (HF) and polycarbonate (PC) production), and general control requirements for certain types of emission points for hazardous air pollutants (HAP). At the time of promulgation of the consolidated rulemaking, EPA deferred taking final action regarding provisions applicable to wastewater streams for the AR, AMF, and PC production source categories based on a need to propose significant changes to the wastewater provisions that were proposed on October 14, 1998 (63 FR 55178). The HF production source category does not have wastewater streams. In parallel with the promulgated consolidated rulemaking package, EPA published a supplemental notice of proposed rulemaking regarding wastewater provisions (64 FR 34950) applicable to wastewater streams for the AR, AMF, and PC production source categories and reopened the public comment period regarding those proposed wastewater provisions.
Today's action promulgates wastewater provisions amendments applicable to wastewater streams for the AR, AMF, and PC production source categories based on EPA's response to comments received on the wastewater provisions proposed on June 29, 1999 (64 FR 34950).
