Sec. 60.165  Monitoring of operations.

    (a) The owner or operator of any primary copper smelter subject to 
Sec. 60.163 (b) shall keep a monthly record of the total smelter charge 
and the weight percent (dry basis) of arsenic, antimony, lead and zinc 
contained in this charge. The analytical methods and procedures employed 
to determine the weight of the total smelter charge and the weight 
percent of arsenic, antimony, lead and zinc shall be approved by the 
Administrator and shall be accurate to within plus or minus ten percent.
    (b) The owner or operator of any primary copper 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 dryer. 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 roaster, 
smelting furnace or copper converter subject to Sec. 60.163 (a). 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 gas 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.
    (c) Six-hour average sulfur dioxide concentrations shall be 
calculated and recorded daily for the four consecutive 6-hour periods of 
each operating day. Each six-hour average shall be determined as the 
arithmetic mean of the appropriate six contiguous one-hour average 
sulfur dioxide concentrations provided by the continuous monitoring 
system installed under paragraph (b) of this section.
    (d) 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 (b) of this section, exceeds the standard under Sec. 
60.164(a).

[[Page 384]]

    (2) Sulfur dioxide. All six-hour periods during which the average 
emissions of sulfur dioxide, as measured by the continuous monitoring 
system installed under paragraph (b) of this section, exceed the level 
of the standard. The Administrator will not consider emissions in excess 
of the level of the standard for less than or equal to 1.5 percent of 
the six-hour periods during the quarter as indicative of a potential 
violation of Sec. 60.11(d) provided the affected facility, including 
air pollution control equipment, is maintained and operated in a manner 
consistent with good air pollution control practice for minimizing 
emissions during these periods. Emissions in excess of the level of the 
standard during periods of startup, shutdown, and malfunction are not to 
be included within the 1.5 percent.
