MENUMENU

Method 319 Compliant System

Title 40 of the Code of Federal Regulations Part 63, Subpart GG (“40 CFR Part 63”), also known as the National Emission Standards for Hazardous Air Pollutants
(“NESHAP”) established (i) standards; (ii) test methods and procedures; (iii)
monitoring requirements; (iv) record keeping requirements and (v) reporting
requirements for aerospace manufacturing and rework facilities.

Specifically with respect to paint application and removal,
the EPA required:

  • All operations to be conducted
    in a spray booth or hangar;
  • Air flow must be downward or
    across the part and must be exhausted through a control device;
    and
  • A control device can be a dry particulate filter
    (also known as a paint arrestor) or water wash system but must meet
    certain minimum standards
    .

The EPA developed a test protocol known as Method 319 to
determine if a dry particulate filter/paint arrestor complies with 40 CFR Part
63.  Method 319 attempts to simulate dry and wet overspray characteristics of
hazardous air pollutants (“HAP”) and volatile organic compounds (“VOC”).
