C. No person shall cause, allow, or permit the discharge of particulate matter into the atmosphere in any one hour from any cotton gin in total quantities in excess of the amounts 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 = 4.10P0.67
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 = 55.0P0.11-40
where “E” and “P” are defined as indicated in subsection (C)(1).
D. The test methods and procedures required by this Section are as follows:
1. The reference methods in the Arizona Testing Manual and 40 CFR 60, Appendix A shall be used to determine compliance with this Section as follows:
