(A) For coatings which are not waterborne (water-reducible),
determine the VOC content of each formulation (less water and less
exempt solvents) as applied using manufacturer's supplied data or
Method 24 of 40 CFR Part 60, Appendix A. If there is a discrepancy
between the manufacturer's formulation data and the results of the
Method 24 analysis, compliance must be based on the results from the
Method 24 analysis. For water-borne (water-reducible) coatings, manufacturer's
supplied data alone can be used to determine the VOC content of each
formulation.
(B) For aqueous and semiaqueous cleaning solvents,
manufacturers' supplied data must be used to determine the water content.
(C) For hand-wipe cleaning solvents, manufacturers'
supplied data or standard engineering reference texts or other equivalent
methods shall be used to determine the vapor pressure or VOC composite
vapor pressure for blended cleaning solvents.
(D) Except for specialty coatings, compliance with
the test method requirements of 40 CFR §63.750, (National Emission
Standards for Aerospace Manufacturing and Rework Facilities), is considered
to represent compliance with the requirements of this section.
(6) Test methods other than those specified in paragraphs
(1) - (5) of this section may be used if validated by 40 CFR Part
63, Appendix A, Test Method 301. For the purposes of this paragraph,
substitute "executive director" each place that Test Method 301 references
"administrator."
