Title 40Chapter ISubchapter CPart 63Subpart RRRRR → §63.9623


Title 40: Protection of Environment
PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES (CONTINUED)
Subpart RRRRR—National Emission Standards for Hazardous Air Pollutants: Taconite Iron Ore Processing


§63.9623   How do I demonstrate initial compliance with the emission limitations that apply to me?

(a) For each affected source subject to an emission limit in Table 1 to this subpart, you must demonstrate initial compliance by meeting the emission limit requirements in paragraphs (a)(1) through (4) of this section.

(1) For ore crushing and handling, the flow-weighted mean concentration of particulate matter, determined according to the procedures in §§63.9620(a) and 63.9621(b), must not exceed the emission limits in Table 1 to this subpart.

(2) For indurating furnaces, the flow-weighted mean concentration of particulate matter, determined according to the procedures in §§63.9620(b) and 63.9621(c), must not exceed the emission limits in Table 1 to this subpart.

(3) For finished pellet handling, the flow-weighted mean concentration of particulate matter, determined according to the procedures in §§63.9620(c) and 63.9621(b), must not exceed the emission limits in Table 1 to this subpart.

(4) For ore dryers, the flow-weighted mean concentration of particulate matter, determined according to the procedures in §§63.9620(d) and 63.9621(c), must not exceed the emission limits in Table 1 to this subpart.

(b) For each affected source subject to an emission limit in Table 1 to this subpart, you must demonstrate initial compliance by meeting the operating limit requirements in paragraphs (b)(1) through (5) of this section.

(1) For each wet scrubber subject to performance testing in §63.9620 and operating limits for pressure drop and scrubber water flow rate in §63.9590(b)(1), you have established appropriate site-specific operating limits and have a record of the pressure drop and scrubber water flow rate measured during the performance test in accordance with §63.9622(a).

(2) On or before January 28, 2022, for affected sources that commenced construction or reconstruction on or before September 25, 2019, for each dynamic wet scrubber subject to performance testing in §63.9620 and operating limits for scrubber water flow rate and either fan amperage or pressure drop in §63.9590(b)(2), you have established appropriate site-specific operating limits and have a record of the scrubber water flow rate and either the fan amperage or pressure drop value, measured during the performance test in accordance with §63.9622(b). After January 28, 2022, for affected sources that commenced construction or reconstruction on or before September 25, 2019, and after July 28, 2020, or upon start-up, which ever date is later, for affected sources that commenced construction or reconstruction after September 25, 2019, for each dynamic wet scrubber subject to performance testing in §63.9620 and operating limits for scrubber water flow rate and fan amperage in §63.9590(b)(2), you have established appropriate site-specific operating limits and have a record of the scrubber water flow rate and the fan amperage value, measured during the performance test in accordance with §63.9622(b).

(3) For each dry electrostatic precipitator subject to performance testing in §63.9620 and one of the operating limits in §63.9590(b)(3), you must meet the requirements in paragraph (b)(3)(i) or (ii) of this section.

(i) If you are subject to the operating limit for opacity in §63.9590(b)(3)(i), you have established appropriate site-specific operating limits and have a record of the opacity measured during the performance test in accordance with §63.9622(c)(1).

(ii) If you are subject to the operating limit for secondary voltage and secondary current in §63.9590(b)(3)(ii), you have established appropriate site-specific operating limits and have a record of the secondary voltage and secondary current measured during the performance test in accordance with §63.9622(c)(2).

(4) For each wet electrostatic precipitator subject to performance testing in §63.9620 and operating limits for secondary voltage, water flow rate, and stack outlet temperature in §63.9590(b)(4), you have established appropriate site-specific operating limits and have a record of the secondary voltage, water flow rate, and stack outlet temperature measured during the performance test in accordance with §63.9622(d).

(5) For other air pollution control devices subject to performance testing in §63.9620 and operating limits in accordance with §63.9590(b)(5), you have submitted a site-specific monitoring plan in accordance with §63.9631(f) and have a record of the site-specific operating limits as measured during the performance test in accordance with §63.9622(e).

(c) For each emission limitation and operating limit that applies to you, you must submit a notification of compliance status according to §63.9640(e).
