Miscellaneous coating manufacturing mact summary

5. What are the testing and initial compliance requirements under this rule?

Owner/operators of an affected source must verify that the required HAP emission reductions have been achieved by either testing or using calculation methodologies.  The methodology used depends on the emission stream characteristics, control device, and the type of process vent.

For example, initial compliance demonstration provisions for stationary process vessels at miscellaneous coating manufacturing sources reference the 40 CFR Part 63, Subpart SS, closed vent system and performance test provisions and the capture efficiency Method 204 in Appendix M to 40 CFR Part 51. Whereas, control devices handling greater than 9.1 Mg/yr (10 tpy) of HAP must be tested, and engineering assessments are allowed for control devices with lower loads and for condensers.

Performance test provisions are based on worst case operating conditions for devices controlling process vents. The initial compliance demonstration procedures reference 40 CFR part 63, Subpart SS, for storage tanks complying using control devices and transfer operations, and 40 CFR part 63, subpart WW, for storage tanks complying using floating roofs.
