Section 1200-03-16-.13 - SECONDARY BRASS AND BRONZE INGOT PRODUCTION(1) Applicability. The provisions of this rule shall apply to the following affected facilities commenced on or after April 21, 1976, in secondary brass or bronze ingot production plants: reverberatory and electric furnaces of 1,000 kg (2,205 lb) or greater production capacity and blast (cupola) furnaces of 250 kg/hr (550 lb/hr) or greater production capacity.(2) Definitions. (a) "Brass or bronze" means any metal alloy containing copper as its predominant constituent and lesser amounts of zinc, tin, lead, or other metals.(b) "Reverberatory furnace" includes the following types of reverberatory furnaces: stationary, rotating, rocking, and tilting.(c) "Electric furnace" means any furnace which uses electricity to produce over fifty (50) percent of the heat required in the production of refined brass or bronze.(d) "Blast furnace" means any furnace used to recover metal from slag.(3) Standard for particulate matter: (a) On and after the date on which the performance test required to be conducted by paragraph .01(5) of this chapter is completed, no owner or operator subject to the provisions of this rule shall discharge or cause the discharge into the atmosphere from a reverberatory furnace any gases which:1. Contain particulate matter in excess of 50 mg/dscm (0.022 gr/dscf).2. Exhibit twenty (20) percent opacity or greater.(b) On and after the date on which the performance test required to be conducted by paragraph .01(5) of this chapter is completed, no owner or operator subject to the provisions of this rule shall discharge or cause the discharge into the atmosphere from any blast (cupola) or electric furnace any gases which exhibit ten (10) percent opacity or greater.(4) Test methods and procedures; For determining the concentration of particulate matter and the associated moisture content, the sampling time for each run shall be at least 120 minutes and the sampling rate shall be at least 0.9 dscm/hr (0.53 dscf/min) except that shorter sampling times, when necessitated by process variables or other factors, may be approved by the Technical Secretary. Particulate matter sampling shall be conducted during representative periods of charging and refining, but not during pouring of the heat.
