methods as may be approved by the director.
(B) Concentrations of carbon monoxide in
ambient air shall be determined as follows:

carbon monoxide shall be determined through the use of a continuous sampling
and recording device as described in 40 CFR part 50, appendix C.
(2) Eight hour concentrations shall be

eight-hour average shall be considered valid if at least seventy-five per cent

shall be computed on the basis of the hours available using six (or seven) as
the divisor.
