Area Source Standards 40 CFR Part 63 - Subpart WWWWWW

Notification of Compliance Status: July 1, 2010

In July of 2008, the U.S. Environmental Protection Agency (U.S. EPA) finalized the National Emission Standards for Hazardous Air Pollutants: Area Source Standards that affect plating and polishing operations that use the compounds Cadmium, Chromium, Manganese, Nickel or Lead and have the potential to emit less than 10 tons per year of any single Hazardous Air Pollutant (HAP) or less than 25 tons per year of a combination of HAPs. Owners or operators of existing sources are required to submit a Notification of Compliance Status by July 1, 2010.

Who is affected by this Regulation?

  • Facilities that are area sources of hazardous pollutants (HAP)
  • Tanks or processes that contain or use any compounds of cadmium, chromium, manganese, nickel or lead in the following ways:
    • Non-cyanide electroplating, electroforming and electropolishing (pH < 12)
    • Flash or short-term electroplating
    • Dry mechanical polishing and thermal spraying
    • Cyanide electroplating (pH ≥12), non-electrolytic plating and coating operations (such as electroless nickel plating and chromate conversion coating)

What are the Requirements?

The regulation requires plating and polishing operations to comply with specific requirements if performing the aforementioned processes. Limiting plating time to 3 minutes per hour or 1 hour per day, utilizing wetting agents or fume suppressants, providing tank covers and employing control devices to exhaust emissions are a few. The regulation requires implementing management practices to minimize or eliminate potential emissions such as, performing regular inspections of tanks to identify leaks and making repairs to racks, barrels and other equipment, practicing general good housekeeping and maintaining quality control of chemicals and bath ingredients in the tanks. Reports and records of compliance with these requirements are also required to be submitted and maintained.
