(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.
