Sec. 3.
(a) On and after January 1, 1999, sinter plant windbox exhaust gas VOC emissions shall be limited as provided in subsections (b) and (c).(b) This subsection establishes three (3) VOC emission limits for the period from May 1 through September 30 for sinter plant windbox exhaust gas VOC emissions, a seasonal cap, a maximum daily limit, and a lower daily limit for days on which an exceedance of the national ambient air quality standard for ozone is predicted to be likely. The emission limits are based on a VOC emission rate equal to twenty-five hundredths (0.25) lb/ton sinter produced and a daily sinter production rate. The VOC emissions on any day are limited to an amount based on maximum actual daily sinter production. However, on a day expected to be a high ozone day, the VOC emissions shall be limited to an amount based on average daily sinter production. Sinter plant windbox exhaust gas VOC emissions shall not exceed the VOC emission limits calculated as follows:(1) During the period May 1 through September 30, the total VOC emissions (the seasonal cap) shall not exceed the VOC emission limit calculated as follows: VOC (lbs) = 0.25 lb/ton of sinter produced × average daily sinter production rate (tons/day) × 153 days
(2) Except as provided in subdivision (3), on any day from May 1 through September 30, the sinter plant windbox exhaust VOC emissions (the maximum daily limit) shall not exceed the VOC emission limit calculated as follows: VOC (lbs/day) = 0.25 lb/ton of sinter produced × maximum actual daily sinter production rate (tons/day)
(3) On any day from May 1 through September 30 when ozone levels in Lake, Porter, or LaPorte County are expected to exceed the national ambient air quality standard for ozone (either one (1) hour or eight (8) hour), the sinter plant windbox exhaust VOC emissions (the lower daily limit) shall not exceed the VOC emission limit calculated as follows: VOC (lbs/day) = 0.25 lb/ton of sinter produced × average daily sinter production rate (tons/day) A high ozone level day shall be predicted by the owner or operator of a source in accordance with a high ozone day action plan developed by the source and submitted to the department as part of the report required by section 4(b) of this rule. Where sinter production rate shall be calculated as follows:
(A) Maximum actual daily sinter production equals the maximum actual sinter produced on an operating day during the period from 1990 to 1997. (B) Average daily sinter production equals either of the following: (i) The annual average sinter production in tons divided by the annual average number of operating days in the period 1990 through 1994.(ii) In the event sinter production in 1990 through 1994 is not representative of the current sinter production due factors, such as, but not limited to, routine repair, maintenance, or replacement, a source may elect to use the average actual sinter production in tons per day during a calendar year up to the year 1997, which represents current sinter production. The averaging period must include and be not less than the ozone season (May 1 through September 30).(c) From October 1 through April 30, sinter plant windbox exhaust gas VOC emissions shall be limited to thirty-six hundredths (0.36) pound per ton of sinter produced. The limit shall be complied with on an operating day average basis.
