Section 113.2135 - How do I convert my 1-hour arithmetic averages into appropriate averaging times and units?

(a) Use the equation in § 113.2171(a) of this title (relating to What equations must I use?) to calculate emissions at 7 percent oxygen.

(b) Use United States Environmental Protection Agency (EPA) Reference Method 19 in 40 Code of Federal Regulations (CFR) Part 60, Appendix A, §4.3, to calculate the daily geometric average concentrations of sulfur dioxide emissions. If you are monitoring the percent reduction of sulfur dioxide, use EPA Reference Method 19 in 40 CFR Part 60, Appendix A, §5.4, to determine the daily geometric average percent reduction of potential sulfur dioxide emissions.

(c) If you operate a Class I municipal waste combustion unit, use EPA Reference Method 19 in 40 CFR Part 60, Appendix A, §4.1, to calculate the daily arithmetic average for concentrations of nitrogen oxides.

(d) Use EPA Reference Method 19 in 40 CFR Part 60, Appendix A, §4.1, to calculate the 4-hour or 24-hour daily block averages (as applicable) for concentrations of carbon monoxide.
