A. No person shall cause, allow or permit the discharge of particulate matter into the atmosphere in any one hour from electric arc furnaces or dust-handling equipment which are affected facilities in any steel plant 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 = 3.59P 0.62
where:
E = The maximum, allowable particulate emission 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 = 17.31P 0.16
where "E" and "P" are defined as indicated in subdivision 1 of this subsection.
B. The 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 used in determining the maximum allowable emission of particulate matter.
D. The opacity standard of forty percent shall not be exceeded by existing steel plant electric arc furnaces and their appurtenances for more than an aggregate of three minutes in any forty-five-minute period.
E. A continuous monitoring system for the measurement of the opacity of emissions discharged into the atmosphere from the control device shall be installed, calibrated, maintained, and operated by the owner or operator subject to the provisions of this section.
F. The test methods and procedures required under this section are as follows:
1. Reference methods in 40 CFR 60, Appendix A shall be used to determine compliance with the standards prescribed under subsection A of this section as follows:
a. Method 4 and 5 for the concentration of particulate matter;
b. Method 1 for sample and velocity traverses;
c. Method 2 for velocity and volumetric flow rate;
d. Method 3 for gas analysis.
2. For Method 5, the sampling time for each run shall be at least four hours. When a single EAF is sampled, the sampling time for each run shall also include an integral number of heats. Shorter sampling times, when necessitated by process variables or other factors, may be approved by the control officer. The minimum sample volume shall be 4.5 dscm (160 dscf).
