Permit Issued To: AIRCRAFT FINISHING CORP 612 RUTGERS RD. NORTH BABYLON, NY 11703 Contact: SAMUEL SERIGANO AIRCRAFT REFINISHING 612 RUTGERS RD NORTH BABYLON, NY 11703 (631) 422-5000 Facility: AIRCRAFT FINISHING CORP 612 RUTGERS RD NORTH BABYLON, NY 11703 Description: Aircraft Finishing Corp. is involved in chromium and sulfuric acid anodizing, cadmium plating, and spray coating of aerospace aluminum and steel parts. The 2 Emission Units of the facility consist of spray coating and cleaning and anodizing of metal parts. The spray coating and metal parts drying unit consists of 3 Emission Points which are associated with three spray booths and one room where the paints and chemicals are prepared. The cleaning, anodizing, and plating unit consits of 3 Emission Points which are associated with emissions from vapor degreasing, caustic cleaning, acid pickling, chromic acid anodizing, sulfuric acid anodizing, electroplating, and rinsing. The spray coating operations are subject to 6 NYCRR Part 228 (Surf ace Coating Processes) and 6 NYCRR Part 212 (General Process Emission Sources) regulations that require the utilization of compliant paints and emissions of toxics below the acceptable concentrations in the atmosphere. The emissions from chromic acid anodizing operations are regulated under 40 CFR Part 63 Subpart N (National Emission Standards for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks). The vapor degreasing operations are regulated under 40 CFR Part 63 Subpart T (National Emission Standards for Halogenated Solvent Cleaning). Aircraft Finishing is also using sulfuric acid and cyanide-based solutions to conduct cleaning and cadmium plating of aerospace parts and the emissions from these processes are regulated by 6 NYCRR Part 212.

Mod 1/FINALFacility DEC ID: 1472000508 By acceptance of this permit, the permittee agrees that the permit is contingent upon strict compliance with the ECL, all applicable regulations, the General Conditions specified and any Special Conditions included as part of this permit.
