I. Organic HAP content limit: 420 s/l (3.5 Ib/gal)(less
Nater) as applied. (63.745(~)(3))
5. VOC content limit: 420 g/l (3.5 Ib/gal) (less water and
:xempt solvents). (63.745(~)(4))6.
5. Achieve compliance as in
3. above. (63.745(e))
:ontrolled Primers and
ropcoats
7. If control system is used, must be designed to capture and
:ontrol all emissions from the application operation and must
ichieve an overall control efficiency of at least 81%.

411 Primers and Topcoats
5. Specific application techniques must be used. If
ilternative is sought, can only be used if emissions are less
than or equal to HVLP or electrostatic spray application
techniques. (63.745(f)( I))
9. All application equipment must be operated according to
manufacturer's specifications, company procedures, or
locally specified operating procedures. (63.745(0(2))
IO. Exemptions from No. 8 above provided for in certain
situations. (63.745(9(3))
1 1. Operating requirements
for the application of primers or topcoats that contain
inorganic HAP, including control with either particulate
filters or waterwash, and shutdown if operated outside
manufacturer's specified limits. (63.745(g)( 1) through (3))
12. Exemptions from No. 11 provided for certain
application operations. (63.745(g)(4))
1. For "compliant" coatings:
each 30-day period.
For "averaged" coatings:
each 30-day period.
For "controlled" coatings,
non-carbon adsorber:
three I-hour runs.
For "controlled" coatings, carbon adsorber:
each rolling period. (63.749(e)(l))
2. Initial performance test for all control devices to
demonstrate compliance with overall control efficiency
requirement. (63.749(e)(2))
