- 715. Standards of Performance for Existing Primary Copper Smelters; Site

- specific Requirements

A. No owner or operator of a primary copper smelter shall cause, allow or permit the discharge of particulate matter into the atmosphere from any proces s in total quantities in excess of the amount calculated by one of the following equations: 1. For process sources having a process weight rate of 60,000 pounds per hour (30 tons per hour) or less, the maximum allowable emissions shall be determined by the following equation:
E = 4.10P 0.67
where E = the maximum allowable particulate emissions rate in pounds

- mass per hour. P = the process weight rate in tons

- mass per hour.
2. For process sources having a process weight rate greater than 60,000 pounds per hour (30 tons per hour), the maximum allowable emissions shall be determined by the following equation:
E = 55.0P 0.11

- 40 where “E” and “P” are defined as indicated in subsectio n (A)(1). B. Actual values shall be calculated from the applicable equations and rounded off to two decimal places. C. For purposes of this Section, the total process weight from all similar units employing a similar type process shall be us ed in
determini ng the maximum allowable emission of particulate matter for that process. D. The opacity of emissions subject to the provisions of this Section shall not exceed 20%. E. The reference methods set forth in the Arizona Testing Manual and 40 CFR 60, Appendix A , as incorporated by reference in Appendix 2 of this Chapter, shall be used to determine compliance with the standards prescribed in this Section as follows: 1. Method A1 or Reference Method 5 for concentration of particulate matter and associated moisture content, 2. Reference Method 1 for sample and velocity traverses, 3. Reference Method 2 for volumetric flow rate, 4. Reference Method 3 for gas analysis. F. Except as provided in a consent decree or a delayed compliance order, the owner or operator of any primary copper smelter shall not discharge or cause the discharge of sulfur dioxide into the atmosphere from any stack required to be monitored by R18

- 715.01(K) in excess of the following: 1. For the copper smelter located near Hayden, Arizona at latitu de 33°0’29”N and longitude 110°47’17” W: a. Annual average emissions, as calculated under R18

- 2

- 715.01(C), shall not exceed 6,882 pounds per hour.
b. The number of three

- hour average emissions, as calculated under R18
