Sec. 60.456  Test methods and procedures.

    (a) The reference methods in appendix A to this part, except as 
provided under Sec. 60.8(b), shall be used to determine compliance with 
Sec. 60.452 as follows:

[[Page 490]]

    (1) Method 24 or formulation data supplied by the coating 
manufacturer to determine the VOC content of a coating. In the event of 
dispute, Method 24 shall be the reference method. For determining 
compliance only, results of Method 24 analyses of waterborne coatings 
shall be adjusted as described in Section 12.6 of Method 24. Procedures 
to determine VOC emissions are provided in Sec. 60.453.
    (2) Method 25 for the measurement of the VOC concentration in the 
gas stream vent.
    (3) Method 1 for sample and velocity traverses.
    (4) Method 2 for velocity and volumetric flow rate.
    (5) Method 3 for gas analysis.
    (6) Method 4 for stack gas moisture.
    (b) For Method 24, the coating sample must be a 1-liter sample taken 
into a 1-liter container at a point where the sample will be 
representative of the coating material.
    (c) For Method 25, the sample time for each of three runs is to be 
at least 60 minutes and the minimum sample volume is to be at least 
0.003 dscm (0.1 dscf) except that shorter sampling times or smaller 
volumes, when necessitated by process variables or other factors, may be 
approved by the Administrator.
    (d) The Administrator will approve sampling of representative stacks 
on a case-by-case basis if the owner or operator can demonstrate to the 
satisfaction of the Administrator that the testing of representative 
stacks would yield results comparable to those that would be obtained by 
testing all stacks.
