On December 2, 1994, the EPA issued the ``National Emission Standards for Hazardous Air Pollutants: Halogenated Solvent Cleaning'' (59 FR 61801). On May 5, 1998, the EPA announced an immediate 3-month stay of the effectiveness of that standard for continuous web cleaning machines using halogenated hazardous air pollutant (HAP) solvents for good cause pursuant to section 553(b)(3)(B) of the Administrative Procedures Act (63 FR 24768). In that same document, the EPA proposed a temporary extension of the applicable compliance date beyond the 3 months of the stay for up to 1 year to complete analysis of equivalent methods of control for continuous web cleaning machines using halogenated HAP solvents. This document promulgates that compliance extension, and for reasons discussed in this notice, extends the compliance extension until December 2, 1999. This document also discusses the three comment letters received on the May 5, 1998 proposal notice.
