Emissions shall be calculated for each operating hour by multiplying the heat input times the applicable emission rate in pounds of sulfur dioxide per MM Btu. The emission rate shall be determined in accordance with paragraph (F) of this rule. The average emission rate shall be calculated using the following equation:
where: Eavg is the arithmetic average emissions in pounds per hour.
Hi is the hourly heat input in MM Btu for hour i. Hi is determined by a computerized system, or by monitoring the hourly steam production rate and back-calculating the heat input in accordance with the heat balance method or other approved equivalent method.
ERi is the emission rate in pounds of sulfur dioxide per MM Btu, determined in accordance with paragraph (F) of this rule. If multiple fuels are used, the emission rate shall be calculated as a weighted average based on the heat input of each fuel burned.
n is the number of operating hours during a period of thirty consecutive operating days. An operating day means a twenty-four-hour period that begins at midnight and ends the following midnight during which any fuel is combusted at any time, except that if the schedule for calculating emission averages is revised, an operating day shall mean a twenty-four-hour period between consecutive scheduled emission average calculations during which any fuel is combusted at any time.
The daily rolling arithmetic average is calculated on a fixed schedule updated at twelve a.m. every operating calendar day unless an alternative fixed daily schedule is approved by the director. The director shall notify the United States environmental protection agency upon the approval of any alternate averaging schedule.
(11) For any fuel burning equipment burning coal at the "Cardinal Power Plant" (OEPA premise number 0641050002) or any subsequent owner or operator of the "Cardinal Power Plant" facility in Brilliant, Ohio, compliance with the sulfur dioxide emissions rate specified in paragraph (D)(3) of rule 3745-18-47 of the Administrative Code shall be demonstrated by calculating an average emission rate in pounds per hour over thirty operating days. Emissions shall be calculated for each operating hour for main boiler unit numbers 1, 2 and 3 (OEPA source numbers B001, B002 and B009), combined, as a summation of the emission rates determined in accordance with paragraph (D)(2) of this rule. The permittee may remove values which were substituted for missing data in accordance with 40 CFR Part 75 Subpart D. Compliance with the combined average sulfur dioxide emission rate shall be calculated using the following equation:
where: Eavg is the arithmetic average SO2 emissions in pounds per hour as a rolling, thirty-operating-day average computed at the end of each operating day.
SO2,B001 = SO2 emissions from emissions unit B001, in pounds/hr for hour i.
SO2,B002 = SO2 emissions from emissions unit B002, in pounds/hr for hour i.
SO2,B009 = SO2 emissions from emissions unit B009, in pounds/hr for hour i.
n = number of operating hours in the rolling, thirty-operating-day averaging period, minus the number of operating hours excluded from the calculation due to missing data.
An operating hour is an hour in which any of units B001, B002 or B009 are operating. An operating day is a day in which any of units B001, B002 or B009 are operating for any portion of the day. A value of Eavg shall be computed for each operating day and the twenty-nine preceding operating days.
