National Emission Standards for Hazardous Air Pollutants: Miscellaneous Coating Manufacturing

This action promulgates amendments to the national emission standards for hazardous air pollutants for miscellaneous coating manufacturing. The amendments clarify that coating manufacturing means the production of coatings using operations such as mixing and blending, not reaction or separation processes used in chemical manufacturing. The amendments extend the compliance date for certain coating manufacturing equipment that is also part of a chemical manufacturing process unit. The amendments also clarify that operations by end users that modify a purchased coating prior to application at the purchasing facility are exempt. These changes clarify applicability of the rule and minimize the compliance burden.
