Riepilogo

EPA is taking direct final action to approve the Delaware Department of Natural Resources and Environmental Control's (DNREC's) request to implement and enforce its hazardous air pollutant general provisions and hazardous air pollutant emission standards for perchloroethylene dry cleaning facilities, hard and decorative chromium electroplating and chromium anodizing tanks, and industrial process cooling towers in place of similar Federal requirements set forth in the Code of Federal Regulations. This approval includes granting authority to DNREC to implement and enforce any future amendments to these provisions and standards that EPA promulgates and DNREC adopts unchanged into its regulations. EPA is not waiving its notification and reporting requirements under this approval; therefore, sources will need to send notifications and reports to both DNREC and EPA. EPA is taking this action in accordance with the Clean Air Act (CAA).
