Sec. 60.144  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.142 as follows:
    (1) The time-measuring instrument of Sec. 60.143 shall be used to 
document the time and duration of each steel production cycle and each 
diversion period during each run.
    (2) 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 1.50 dscm (53 dscf). Sampling shall be 
discontinued during periods of diversions.
    (i) For affected facilities that commenced construction, 
modification, or reconstruction on or before January 20, 1983, the 
sampling for each run shall continue for an integral number of steel 
production cycles. A cycle shall start at the beginning of either the 
scrap preheat or the oxygen blow and shall terminate immediately before 
tapping.
    (ii) For affected facilities that commenced construction, 
modification, or reconstruction after January 20, 1983, the sampling for 
each run shall continue for an integral number of primary oxygen blows.
    (3) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity. Observations taken during a diversion period shall 
not be used in determining compliance with the opacity standard. Opacity 
observations taken at 15-second intervals immediately before and after a 
diversion of exhaust gases from the stack may be considered to be 
consecutive for the purpose of computing an average opacity for a 6-
minute period.
    (c) The owner or operator shall use the monitoring devices of Sec. 
60.143(b)(1) and (2) for the duration of the particulate matter runs. 
The arithmetic average of all measurements taken during these runs shall 
be used to determine compliance with Sec. 60.143(c).
