   5. (E) The concentration of condensable particulate matter

7. (CPM) emissions in stack gases shall be determined using Method 202 and Conditional Test Method 039 as specified by 40 CFR part 51, Appendix M in section (21) of this rule may be used to determine the total PM10 and PM2.5 fraction of filterable particulate matter including condensables.

   1. (F) The concentration of PM2.5 emissions in stack gases shall be determined using Method 202 and Conditional Test Method 040 as specified by 40 CFR part 51, Appendix M in section (21) of this rule. EPA Conditional Test Method 039 as specified in 40 CFR part 51, Appendix M in section (21) of this rule may be used to determine the total PM10 and PM2.5 fraction of filterable particulate matter including condensables.
8. (6) The sulfur dioxide emissions from air pollution sources shall be determined using Method 6 as specified by 40 CFR part 60, Appendix A in section (22) of this rule.

15. (13) The total fluoride emissions and the associated moisture content from air pollution sources shall be determined using Method 13A and 13B as specified by 40 CFR part 60, Appendix A in section (22) of this rule. For Method 13A or 13B, the sampling time for each run shall be at least sixty (60) minutes and the minimum sample volume shall be at least 0.85 standard dry cubic meter (thirty (30) standard dry cubic foot) except that shorter sampling times or smaller volumes, when necessitated by process variables or other factors, may be approved by the director.
