in this appendix shall be performed in accordance with 40 CFR 60, Appendix 

A; 40 CFR 51 Appendix M; and R307-305-3, Utah Air Conservation Rules. The 

back half condensibles are required for inventory purposes. The following test 

methods shall be used for the indicated air contaminants: 

PM,, For stacks in which no liquid drops are present, the following methods 

shall be used: 40 CFR 51, Appendix M, Methods 201 or 201a plus the 

back half condensibles using Method 202, or other appropriate EPA 

approved reference method. 

For stacks in which liquid drops are present, methods to eliminate the 

liquid drops should be explored. If no reasonable method to eliminate 

the drops exists, then the following methods shall be used: 40 CFR 

60, Appendix A, Method 5, 5a, 5d, 5e, plus back half condensibles 

using method 202, or other appropriate EPA approved reference 

method. All particulate captured in the back half shall be considered
