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).
