## Abstract

The EPA is taking direct final action to extend certain compliance dates contained in national emission standards for hazardous air pollutant emissions for Group IV polymers and resins for the equipment leaks provisions as applied to polyethylene terephthalate (PET) affected sources. We are approving this compliance extension pursuant to section 301(a)(1) of the Clean Air Act (CAA) to complete reconsideration of equipment leaks provisions and any necessary revision to the rule. We are also correcting a referencing error.
