(x)
The perfluorocarbon compounds which fall into these classes:
(1)
cyclic, branched, or linear, completely fluorinated alkanes:
(2)
cyclic, branched,or linear, completely fluorinated ethers with no
unsaturations ;
(3)
cyclic, branched, or linear, completely fluorinated tertiary amines
with no unsaturations ; and
(4)
sulfur containing perfluorocarbons with no unsaturations and with
sulfur bonds only to carbon and fluorine.
These compounds have been determined to have negligible photochemical reactivity.
For purposes of determining compliance with emission limits, VOC will be measured
by the approved test methods. Where such a method also inadvertently measures
compounds with negligible photochemical reactivity as defined above, an owner or
operator may exclude these negligible photochemical reactive compounds when
determining compliance with an emissions standard. Exempt solvents will be treated as
water in "pounds of VOC per gallon of coating minus water" calculations.
