Section R. 336.2175 - Data reduction procedures for fossil fuel-fired steam generatorsRule 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: Click Here To View Image
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: Click Here To View Image
(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.Mich. Admin. Code R. 336.2175
