(c) In the event a commercial bakery oven facility meets paragraph (A)(1)(a) of this rule, but reduces the total uncontrolled potential to emit for volatile organic compounds to less than one hundred tons per year by no later than May 27, 2006, the facility is not subject to paragraphs (D) to (I) of this rule. If such commercial bakery oven facility subsequently meets paragraph (A)(1)(a) of this rule, then the facility becomes subject to paragraphs (D) to (I) of this rule.

(2) Applicability for the Cleveland-Akron-Lorain area.

(a) Except as otherwise provided in paragraph (A)(2)(b) of this rule, paragraphs (D) to (I) of this rule shall apply to each commercial bakery oven facility that meets both of the following criteria:

(i) The facility is located in any of the following counties: Ashtabula, Cuyahoga, Geauga, lake, Lorain, Medina, Portage, or Summit .

(ii) The facility has a total uncontrolled potential to emit for VOC emissions equal to or greater than one hundred tons per year on or after August 25, 2008, as determined in accordance with paragraph (C) of this rule.

(b) Once a commercial bakery oven facility meets paragraph (A)(2)(a) of this rule on or after August 25, 2008, the facility is always subject to paragraphs (D) to (I) of this rule, except as otherwise provided in paragraph (A)(2)(c) of this rule.

(c) In the event a commercial bakery oven facility meets paragraph (A)(2)(a) of this rule, but reduces the total uncontrolled potential to emit for VOCs to less than one hundred tons per year by no later than August 25, 2009, the facility is not subject to paragraphs (D) to (I) of this rule. If such commercial bakery oven facility subsequently meets paragraph (A)(2)(a) of this rule, then the facility becomes subject to paragraphs (D) to (I) of this rule.

(B) Definitions.

The definitions applicable to this rule are contained in paragraphs (B) and (U) of rule 3745-21-01 of the Administrative Code.

(C) Determination of total uncontrolled potential to emit.

(1) The owner or operator of each commercial bakery oven facility shall calculate the facility's total uncontrolled potential to emit, UPTE(facility), for VOC emissions in tons per year, using either the equations in paragraphs (C)(1)(a) to (C)(1)(c) of this rule and the provisions in paragraphs (C)(2) to (C)(4) of this rule, or a USEPA administrator-approved alternative method if the use of that alternative method is approved in writing by the USEPA administrator for this purpose:

(a) UPTE(facility) equals the sum of the UPTE(oven) for all bakery ovens at the facility (in tons VOC per year)

(b) UPTE(oven) is calculated for each bakery oven as follows:

UPTE(oven) =PA * EF VOC * (1 ton/2000 pounds)

where:

PA = the bakery oven's maximum annual production rate for yeast-leavened finished bakery product (in tons of baked product per year).

EFVOC = VOC emission factor for the bakery oven's yeast-leavened finished bakery product having the highest emission potential (in pounds of VOC per ton of baked product) for the bakery oven.

(c) The value of EFVOC , expressed in pounds of VOC per ton of baked product (roundedoff to two decimal places), is determined as follows:

where:

Yi = initial baker's per cent of yeast to the nearest tenth of a per cent.

t i= total yeast action time in hours to the nearest tenth of an hour.

S = final (spike) baker's per cent of yeast to the nearest tenth of a per cent.

ti = spiking time in hours to the nearest tenth of an hour.

(2) The owner or operator shall presume for purposes of calculating the uncontrolled potential to emit that both of the following conditions apply:

(a) Each facility production line and associated bakery oven are operating eight thousand seven hundred sixty hours per year at maximum capacity.

(b) Each facility production line is producing the product with the highest level of VOC emissions of those products that it may produce.

(3) A VOC emission factor based on emission testing can be used to calculate the facility's total uncontrolled potential to emit for VOC in tons per year. In the event emission testing is conducted, the emission testing results would be used instead of the VOC emission factor equation in paragraph (C)(1)(c) of this rule. Such emission testing shall be based on the test methods and procedures specified under paragraph (F) of this rule.

(4) The presumptions of paragraph (C)(2) of this rule would not apply where restrictions on operating hours or annual production rate are specified for the commercial bakery oven facility within a federally enforceable permit-to-install and operate or a Title V permit that is issued pursuant to Chapter 3745-31 or Chapter 3745-77, respectively, of the Administrative Code as follows:

(a) For bakery ovens that are located within a county specified in paragraph (A) (1)(a)(i) of this rule and for which installation commenced before May 27, 2005, such restrictions shall be in effect no later than May 27, 2006.

(b) For bakery ovens that are located within a county specified in paragraph (A) (1)(a) (i) of this rule and for which installation commenced on or after May 27, 2005, such restrictions shall be in effect upon initial startup of the bakery oven.

(c) For bakery ovens that are located within a county specified in paragraph (A)(2)(a)(i) of this rule and for which installation commenced before August 25, 2008, such restrictions shall be in effect no later than August 25, 2009.

(d) For bakery ovens that are located within a county specified in paragraph (A)(2)(a)(i) of this rule and for which installation commenced on or after August 25, 2008, such restrictions shall be in effect upon initial startup of the bakery oven.

(D) VOC emission control requirements.

(1) Except where exempted under paragraph (D)(2) of this rule, any owner or operator of a commercial bakery oven facility that is subject to this rule shall install and operate a VOC emission control system that reduces the VOC emissions from each bakery oven by at least ninety-five per cent by weight (i.e., an overall control efficiency of at least ninety-five per cent by weight).

(2) Exempted from paragraph (D)(1) of this rule is any uncontrolled bakery oven with annual VOC emissions of less than 25.0 tons and average daily VOC emissions of less than one hundred ninety-two pounds. Average daily VOC emissions means the VOC emissions from a bakery oven in a calendar year (annual VOC emissions) divided by the number of days the bakery oven was employed for production during the calendar year.

(E) Compliance dates.

(1) Except where otherwise specified within this rule, any owner or operator of a commercial bakery oven facility that is subject to this rule shall comply with this rule by no later than the following dates:
