(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 [[Page 97]] 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.
