PURPOSE: This regulation restricts the emission of volatile organic compounds from bakery ovens at large commercial bakeries.

Editor’s Note: The secretary of state has determined that the publication of this rule in its entirety would be unduly cumbersome or expensive. The entire text of the material referenced has been filed with the secretary of state. This material may be found at the Office of the Secretary of State or at the headquarters of the agency and is available to any interested person at a cost established by state law.

1. (1) Definitions. Definitions of some of the terms used in this rule may be found in 10 CSR 10-6.020 Definition and Common Reference Tables.

2. (2) Applicability.

   1. (A) This rule shall apply only in Clay, Platte and Jackson Counties.
   2. (B) This rule shall apply to existing commercial bakeries whose potential emissions of volatile organic compounds (VOCs) are greater than one hundred tons per year (100 tpy). These bakeries shall demonstrate compliance with this rule by January 1, 1997.
   3. (C) This rule shall apply to new or modified commercial bakeries whose potential emissions of VOCs are greater than one hundred (100) tpy upon start-up.
3. (3) Requirement. Existing or new commercial bakeries which meet the applicability level in subsections (2)(A), (B) and (C) shall install VOC emissions control device(s) in order to achieve at least ninety percent (90%) destruction and capture efficiencies or achieve at least eighty percent (80%) total removal efficiency on the combined emissions of all baking ovens.

4. (4) Determination of Compliance. Compliance with this rule shall be determined by the following methods:

   1. (A) The destruction efficiency shall be determined by using Environmental Protection Agency (EPA) Test Method 25A or another equivalent method that is approved by the director.
   2. (B) The amount of VOC per ton of baked bread shall be based on the EPA emission factors published in the Environmental Protection Agency document entitled “Alternative Control Technology Document for Bakery Oven Emissions,” EPA 453/R-92- 017, December 1992, or administratorapproved alternative methods determined Specific to the Kansas City Metropolitan Area

through stack testing or administratorapproved industry literature. Alternative methods must be approved by the director.

1. (C) The capture efficiency of the air pollution control device shall be determined using the method referenced in 10 CSR 10- 6.030(20) or by an administrator-approved alternative method. Alternative methods must be approved by the director.

1. (5) Recordkeeping.

   1. (A) The owner or operator of a bakery oven shall maintain a daily record of operations. The daily records shall include at least:

      1. 1. The amount of raw material pro-

cessed;

1. 2. The percentage of yeast used;
2. 3. The fermentation time;
3. 4. The type of product baked;
4. 5. The amount of product baked;
5. 6. The emission factor used for each

product; and

1. 7. The quarterly emissions.

2. (B) Bakery owners or operators employing VOC emission control device(s) shall, as applicable, continuously monitor and record the following parameters of such device(s) while the bakery oven is in operation:

   1. 1. Exhaust temperature of all combus-

tion devices, if used. Combustion devices must be operated at temperatures high enough to achieve optimum destruction efficiency. The optimum operating temperatures will be established by the department at the time of compliance determination;

1. 2. Temperature rise across a catalytic

oxidation bed, if used;

1. 3. Exit stream temperature on all con-

densers, if used; and

1. 4. Any other monitoring parameters as

found necessary by the director.

1. (C) Records under subsections (5)(A) and

1. (B) shall be retained by the owner or operator for a minimum of five (5) years. These records shall be made available to the representatives of the Missouri Department of Natural Resources upon request.
2. (6) Compliance Schedules. Any bakery owner or operator of an existing source subject to this rule shall submit a compliance plan to the director within three (3) months of the rule effective date. The compliance plan shall include, but shall not be limited to, control device description, testing protocol, date of compliance, and an operating and maintenance plan for the control device(s). The owner or operator must implement the approved plan and demonstrate compliance with this rule by January 1, 1997.
