                          Primary Lead Smelting

 

Sec.  63.1543  Standards for process and process fugitive sources.



    (a) No owner or operator of any existing, new, or reconstructed 

primary lead smelter shall discharge or cause to be discharged into the 

atmosphere lead compounds in excess of 500 grams of lead per megagram of 

lead metal produced (1.0 pounds of lead per ton of lead metal produced) 

from the aggregation of emissions discharged from the air pollution 

control devices used to control emissions from the sources listed in 

paragraphs (a)(1) through (a)(9) of this section.

    (1) Sinter machine;

    (2) Blast furnace;

    (3) Dross furnace;

    (4) Dross furnace charging location;

    (5) Blast furnace and dross furnace tapping location;

    (6) Sinter machine charging location;

    (7) Sinter machine discharge end;

    (8) Sinter crushing and sizing equipment; and

    (9) Sinter machine area.

    (b) The process fugitive sources listed in paragraphs (a)(4) through 

(a)(8) of this section shall be equipped with a hood and shall be 

ventilated to a baghouse or equivalent control device. The hood design 

and ventilation rate shall be consistent with American Conference of 

Governmental Industrial Hygienists recommended practices.

    (c) The sinter machine area shall be enclosed in a building that is 

ventilated to a baghouse or equivalent control device at a rate that 

maintains a positive in-draft through any doorway opening.

    (d) Except as provided in paragraph (e) of this section, following 

the initial test to demonstrate compliance with paragraph (a) of this 

section, the owner or operator of a primary lead smelter

shall conduct a compliance test for lead compounds on an annual basis 

(no later than 12 calendar months following any previous compliance 

test).

    (e) If the three most recent compliance tests demonstrate compliance 

with the emission limit specified in paragraph (a) of this section, the 

owner or operator of a primary lead smelter shall be allowed up to 24 

calendar months from the last compliance test to conduct the next 

compliance test for lead compounds.

    (f) The owner or operator of a primary lead smelter shall maintain 

and operate each baghouse used to control emissions from the sources 

listed in paragraphs (a)(1) through (a)(9) of this section such that the 

alarm on a bag leak detection system required under Sec.  63.1547(c)(9) 

does not sound for more than five percent of the total operating time in 

a 6-month reporting period.

    (g) The owner or operator of a primary lead smelter shall record the 

date and time of a bag leak detection system alarm and initiate 

procedures to determine the cause of the alarm according to the 

corrective action plan required under Sec.  63.1547(c)(9) within 1 hour 

of the alarm. The cause of the alarm shall be corrected as soon as 

practicable.
