Sec. 60.143  Monitoring of operations.

    (a) The owner or operator of an affected facility shall maintain a 
single time-measuring instrument which shall be used in recording daily 
the time and duration of each steel production cycle, and the time and 
duration of any diversion of exhaust gases from the main stack servicing 
the BOPF.
    (b) The owner or operator of any affected facility that uses venturi 
scrubber emission control equipment shall install, calibrate, maintain, 
and continuously operate monitoring devices as follows:
    (1) A monitoring device for the continuous measurement of the 
pressure loss through the venturi constriction of the control equipment. 
The monitoring device is to be certified by the manufacturer to be 
accurate within 250 Pa (1 
inch water).
    (2) A monitoring device for the continual measurement of the water 
supply pressure to the control equipment. The monitoring device is to be 
certified by the manufacturer to be accurate within 5 percent of the design water supply pressure. The 
monitoring device's pressure sensor or pressure tap must be located 
close to the water discharge point. The Administrator must be consulted 
for approval in advance of selecting alternative locations for the 
pressure sensor or tap.
    (3) All monitoring devices shall be synchronized each day with the 
time-measuring instrument used under paragraph (a) of this section. The 
chart recorder error directly after synchronization shall not exceed 
0.08 cm (\1/32\ inch).
    (4) All monitoring devices shall use chart recorders which are 
operated at a minimum chart speed of 3.8 cm/hr (1.5 in/hr).
    (5) All monitoring devices are to be recalibrated annually, and at 
other times as the Administrator may require, in accordance with the 
procedures under Sec. 60.13(b).
    (c) Any owner or operator subject to the requirements of paragraph 
(b) of this section shall report to the Administrator, on a semiannual 
basis, all measurements over any 3-hour period that average more than 10 
percent below the average levels maintained during the most recent 
performance

test conducted under Sec. 60.8 in which the affected facility 
demonstrated compliance with the mass standards under Sec. 
60.142(a)(1), (b)(1)(i) or (b)(2)(i). The accuracy of the respective 
measurements, not to exceed the values specified in paragraphs (b)(1) 
and (b)(2) of this section, may be taken into consideration when 
determining the measurement results that must be reported.
