## Abstract

EPA is amending certain regulations to reflect the current delegation status of national emission standards for hazardous air pollutants in California. Several local air pollution control agencies in California have requested delegation of these Federal standards as they apply to non-major sources. The purpose of this action is to approve those delegation requests and update the listing in the Code of Federal Regulations.
