NR 440.42(5)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2). NR 440.42(5)(b)(b) The owner or operator shall determine compliance with the particulate matter standards in sub. (3) as follows: NR 440.42(5)(b)1.1. Method 5 shall be used to determine the particulate matter concentration. The sampling time and sample volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf). Sampling shall begin no less than 30 minutes after startup and shall terminate before shutdown procedures begin. NR 440.42 HistoryHistory: Cr. Register, January, 1984, No. 337, eff. 2-1-84; am.
