326 IAC 10-3-1 Applicability

Sec. 1. (a) This rule applies to any of the following: (1) A Portland cement kiln with process rates equal to or greater than the following: (A) For long dry kilns, twelve (12) tons per hour (tph). (B) For long wet kilns, ten (10) tph. (C) For preheater kilns, sixteen (16) tph. (D) For precalciner and combined preheater and precalciner kilns, twenty-two (22) tph. (2) The following affected boilers: Source Point ID Unit (A) ArcelorMittal Burns Harbor 075 Boiler #7 076 Boiler #8 077 Boiler #9 078 Boiler #10 079 Boiler #11 080 Boiler #12 (B) ArcelorMittal Indiana Harbor 020 Boiler #4 021 Boiler #5 022 Boiler #6 023 Boiler #7 024 Boiler #8 (3) Any other blast furnace gas-fired boiler defined as a large affected unit under 326 IAC 10-2- 2(c)(11). (b) A unit subject to this rule and a New Source Performance Standard, a National Emission Standard for Hazardous Air Pollutants, or an emission limit established under 326 IAC 2 must comply with the limitations and requirements of the more stringent rule. For a unit subject to this rule and 326 IAC 10-1, compliance with the emission limits in section 3(a)(1)(A) of this rule during the ozone control period is deemed to be compliance with the emission limits in 326 IAC 10-1-4(b)(1) during the ozone control period, and the limits supersede those in 326 IAC 10-1-4(b)(1) during the ozone control period. (c) The requirements of this rule apply to the specific units subject to this rule during startup and shutdown periods and periods of malfunction. (d) During periods of blast furnace reline, startup, and periods of malfunction, the affected boilers are not required to meet the requirement of greater than fifty percent (50%) of the heat input from blast furnace gas.
