06-096 C.M.R. ch. 100, § 176 - Volatile Organic Compounds (VOC)

"Volatile Organic Compounds" means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions.

This definition excludes organic compounds which EPA has determined to have negligible photochemical reactivity as listed in 40 C. F. R. Part 51. 100(s)(1) as amended up to July 1, 2015.

For purposes of determining compliance with emissions limits, VOC shall be measured by the test methods specified under the Department's regulations or 40 C. F. R. Part 60, Appendix A, as applicable. Where such a method also measures compounds with negligible photochemical reactivity, these negligibly-reactive compounds shall not be considered VOC if the amount of such compounds can be and is accurately quantified. As a precondition to excluding these compounds for purposes of determining compliance with an emission standard, the Department may require an owner or operator to provide monitoring or testing methods and results demonstrating, to the satisfaction of the Department the amount of negligibly-reactive compounds in the source's emissions.
