Sec. 60.185  Monitoring of operations.

    (a) The owner or operator of any primary lead smelter subject to the 
provisions of this subpart shall install and operate:
    (1) A continuous monitoring system to monitor and record the opacity 
of gases discharged into the atmosphere from any blast furnace, dross 
reverberatory furnace, or sintering machine discharge end. The span of 
this system shall be set at 80 to 100 percent opacity.
    (2) A continuous monitoring system to monitor and record sulfur 
dioxide emissions discharged into the atmosphere from any sintering 
machine, electric furnace or converter subject to Sec. 60.183. The span 
of this system shall be set at a sulfur dioxide concentration of 0.20 
percent by volume.
    (i) The continuous monitoring system performance evaluation required 
under Sec. 60.13(c) shall be completed prior to the initial performance 
test required under Sec. 60.8.
    (ii) For the purpose of the continuous monitoring system performance 
evaluation required under Sec. 60.13(c), the reference method referred 
to under the Relative Accuracy Test Procedure in Performance 
Specification 2 of appendix B to this part shall be Method 6. For the 
performance evaluation, each concentration measurement shall be of one 
hour duration. The pollutant gases used to prepare the calibration gas 
mixtures required under Performance Specification 2 of appendix B, and 
for calibration checks under Sec. 60.13(d), shall be sulfur dioxide.
    (b) Two-hour average sulfur dioxide concentrations shall be 
calculated and recorded daily for the twelve consecutive two-hour 
periods of each operating day. Each two-hour average shall be determined 
as the arithmetic mean of the appropriate two contiguous one-hour 
average sulfur dioxide concentrations provided by the continuous 
monitoring system installed under paragraph (a) of this section.
    (c) For the purpose of reports required under Sec. 60.7(c), periods 
of excess emissions that shall be reported are defined as follows:
    (1) Opacity. Any six-minute period during which the average opacity, 
as measured by the continuous monitoring system installed under 
paragraph (a) of this section, exceeds the standard under Sec. 
60.184(a).
    (2) Sulfur dioxide. Any two-hour period, as described in paragraph 
(b) of this section, during which the average emissions of sulfur 
dioxide, as measured by the continuous monitoring system installed under 
paragraph (a) of this section, exceeds the standard under Sec. 60.183.
