This amendment clarifies that the emission control requirements of the plating and polishing area source NESHAP do not apply to any bench-scale activities.  In addition, the amendments include several technical corrections and clarifications that do not make significant changes in the rule's requirements.

 

 

• Nonchromium electroplating,

• Electropolishing,

• Electroforming, 

• Electroless plating (including thermal metal spraying, chromate conversion coating, and coloring), or 

• Mechanical polishing of metals and formed products for the trade. 

 

• 33251 Hardware Manufacturing; 

• 332116 Metal Stamping; 

• 332722 Bolt, Nut, Screw, Rivet, and Washer Manufacturing; 

• 332811 Metal Heat Treating; 

• 332812 Metal Coating, Engraving (except Jewelry and Silverware), and Allied Services to Manufacturers; 

• 332913 Plumbing Fixture Fitting and Trim Manufacturing; 

• 332919 Other Metal Valve and Pipe Fitting Manufacturing; 

• 332999 All Other Miscellaneous Fabricated Metal Product Manufacturing; and 

• 336412 Aircraft Engine and Engine Parts Manufacturing; 

 

NOTE: For chromium electroplating and chromium anodizing sources see 40 CFR Part 63, Subpart N, “Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks.”

 

Background
On June 12, 2008, EPA issued final air toxics standards for the plating and polishing area source category.  This final rule established emission standards in the form of management practices for new and existing tanks, thermal spraying equipment, and mechanical polishing equipment in certain plating and polishing processes. The final emission standards reflect EPA's determination regarding the generally achievable control technology (GACT) and management practices for the area source category.  The compliance date for this rule was July 1, 2010.
