This action amends the national emission standards for hazardous air pollutants (NESHAP) for secondary lead smelting by extending by six months the compliance date of the rule and the dates on which existing smelters must submit standard operating procedures (SOP) manuals. This action also sets the deadline for requests for extension of compliance at June 23, 1997. The current rule requires existing smelters to submit SOP manuals for baghouses and fugitive dust control by December 23, 1996, and to achieve compliance with the rule by June 23, 1997. The EPA is currently planning to revise portions of the final rule to address comments received in petitions for reconsideration. These revisions, which are scheduled to be published in February 1997, will materially effect the content of the SOP manuals and the air pollution controls needed to comply with the rule. Today's action is being taken to allow affected facilities adequate time to incorporate the revised requirements into their SOP manuals and to have sufficient time to comply with the emission standards in the rule. This revised compliance date remains within the three year period for compliance allowed by section 112 (i)(3)(A) of the Clean Air Act. DATE(S): Effective date: This final action will be effective on December 12, 1996 unless EPA receives adverse public comment on this document by January 13, 1997. In the event that EPA receives adverse public comment, the Agency will withdraw this rule and issue a proposal to extend the effective date to comply with the rule and to submit SOP manuals.
