;
or
.
(c) Any gaseous fuel with a total sulfur
content no greater than twenty grains of sulfur per one hundred standard cubic

million, or a concentration of CO
2 above four hundred parts per
million

.
(b)
Ambient air conditioned and purified by a CEMS for which the CEMS manufacturer
or vendor certifies that the particular CEMS model produces conditioned gas
that does not contain concentrations of SO
2, NOx, or total hydrocarbons
above one tenth part per million, a concentration of CO above one part per
million, or a concentration of CO
2 above four hundred parts per
million.
(c) For dilution-type
CEMS, conditioned and purified ambient air provided by a conditioning system
concurrently supplying dilution air to the CEMS
