Rule 1175.
(1) The
owner or operator of a fossil fuel-fired steam generator that is subject to the
provisions of this part shall convert gaseous emission monitoring data in parts
per million to pounds per million Btu's using either of the following
procedures:
(a) When the owner or operator
elects to measure oxygen in the flue gases, the measurements of the pollutant
concentration and oxygen concentration shall each be on a consistent basis (wet
or dry). When measurements are on a dry basis, the following conversion
procedure shall be used:

When measurements are on a wet basis, alternative procedures
approved by the department shall be used.
(b) When the owner or operator elects to
measure carbon dioxide in the flue gases, the measurements of the pollutant
concentration and carbon dioxide concentration shall each be on a consistent
basis (wet or dry) and the following conversion procedure shall be used:

(2) The values used in the equations in
subrule (1) of this rule shall be derived as follows:
(a) "E" is the pollutant emission in pounds
per million Btu's.
(b) "C" is the
pollutant concentration in pounds per dry standard cubic foot determined by
multiplying the average concentration, in parts per million, for each hourly
period by 2.59 X 10-9 M pounds per dry standard cubic foot per part per million
where M is the pollutant molecular weight in pounds per pound mole (M equals
64.07 for sulfur dioxide and 46.01 for oxides of nitrogen).
(c) "%
02" or "%
C02" is the oxygen or carbon dioxide
volume, expressed as percent, determined with equipment required by R
336.2101.
(d) "F" or "Fc" is a
factor representing a ratio of the volume of dry flue gases generated to the
calorific value of the fuel combusted (F) or a factor representing a ratio of
the volume of carbon dioxide generated to the calorific value of the fuel
combusted (Fc). Values of F and Fc are listed in the standards of performance
for new stationary sources, 40 C.F.R.§60.45(f), adopted by reference in R
336.1299.
An obvious error in R
336.2175 was corrected at the request of the promulgating agency, pursuant to
Section 56 of 1969 PA 306, as amended by 2000 PA 262, MCL 24.256. The rule
containing the error was published in Michigan Register, 2014
MR 9. The memorandum requesting the correction was published in
