The owner or operator must document five parameters: (A) All 24-hour daily block geometric average concentrations of sulfur dioxide emissions or average percent reductions of sulfur dioxide emissions. (B) For Class I municipal waste combustion units only, all 24-hour daily arithmetic average concentrations of nitrogen oxides emissions. (C) All 4-hour block or 24-hour daily block arithmetic average concentrations of carbon monoxide emissions. (D) All 4-hour block arithmetic average load levels of the municipal waste combustion unit. (E) All 4-hour block arithmetic average flue gas temperatures at the inlet of the particulate matter control device. (c) Records of exceedances. The owner or operator must document three items as follows: (A) Calendar dates whenever any of the five pollutant or parameter levels recorded in subsection (b) of this section or the opacity level recorded in (a)(1) of this section did not meet the emission limits or operating levels specified in this rule. (B) Reasons the applicable emission limits or operating levels were exceeded. (C) Corrective actions undertaken, or are taking, to meet the emission limits or operating levels. (d) Records of minimum data. The owner or operator must document three items as follows: (A) Calendar dates for which the owner or operator did not collect the minimum amount of data required under OAR 340-230-0383(7) and 340-230-0387(5). Record those dates for five types of pollutants and parameters: (i) Sulfur dioxide emissions. (ii) For Class I municipal waste combustion units only, nitrogen oxides emissions. (iii) Carbon monoxide emissions. (iv) Load levels of the municipal waste combustion unit. (v) Temperatures of the flue gases at the inlet of the particulate matter control device. (B) Reasons the minimum data was not collected. (C) Corrective actions the owner or operator took or is taking to obtain the required amount of data. (e) Records of exclusions.
