PURPOSE: This rule reduces volatile organic compound emissions in the St. Louis metropolitan area as part of the Missouri State Implementation Plan for Ozone. 10 CSR 10-5

1. (1) Application.

   1. (A) This rule shall apply throughout St. Louis City and Jefferson, St. Charles, Franklin and St. Louis Counties.
   2. (B) This rule applies to all installations which have the uncontrolled potential to emit more than one hundred (100) tons per year or two hundred fifty kilograms (250 kg) per day of volatile organic compounds (VOCs) from any polyethylene bag sealing operation. This rule also shall apply to any installation which does not have an allowable VOCs emission limit established under 10 CSR 10-6.060 or legally enforceable state implementation plan revision and which has uncontrolled potential emissions greater than or equal to two hundred fifty kilograms (250 kg) per day or one hundred (100) tons per year. The uncontrolled potential to emit is the potential emissions (as defined) plus the emissions removed by control devices.
2. (2) Definitions of certain terms specified in this rule may be found in 10 CSR 10-6.020.
3. (3) Emission Limits. No owner or operator shall use or permit the use of any polyethylene bag sealing operations unless the operations are equipped with a control method that will remove, destroy or prevent discharge into the ambient air a daily average of no less than sixty-five percent (65%) by weight of uncontrolled VOC emissions.

4. (4) Reporting and Recordkeeping.

   1. (A) The owner or operator of a polyethylene bag sealing operation covered by this rule must maintain records consisting of the compositions and amount of sealant used, the amount and type of solvent used, the amount and type of clean-up solvent used and discarded, maintenance and repairs of air pollution control equipment, results of any emissions testing and all other information necessary to determine daily compliance with this rule. The information shall be made available to the director upon request.

   2. (B) For owners or operators utilizing addon control technology, the following parameters will be monitored:

      1. 1. Exhaust gas temperature of all incin-

erators;

1. 2. Temperature rise across a catalytic

incinerator bed;

1. 3. VOC breakthrough on a carbon

adsorption unit; and

1. 4. Any other parameter requested by the

director.

1. (C) Inventory records of all information required in subsections (4)(A) and (B) shall be kept for a period of not less than two (2) years and all those records shall be made available to the director upon his/her request.
2. (D) For add-on control technology, compliance with this rule shall be determined by the testing methods referenced in 10 CSR 10- 6.030(14)(A).

1. (5) Compliance Schedules.

   1. (A) The owner or operator of a polyethylene bag sealing operation achieving compliance with section (3) of this rule through the use of add-on control equipment must meet the applicable increments of progress in the following schedule:

      1. 1. Award contracts, issue purchase

orders or otherwise order the emission control system and process equipment before April 1, 1983;

1. 2. Complete installation of the emission

control equipment before March 1, 1984; and

1. 3. Achieve final compliance, determined

in accordance with subsection (4)(D) before April 1, 1984.

1. (B) The owner or operator of a polyethylene bag sealing operation achieving compliance with section (3) of this rule through the use of exempted solvents must achieve—

   1. 1. A five percent (5%) reduction in

emissions by March 31, 1983;

1. 2. A thirty-five percent (35%) reduction

in emissions by March 31, 1984; and

1. 3. A final compliance by March 31,

1985.

1. (C) In the event that an installation utilizing exempted solvents cannot achieve the emissions reduction required in section (3) of this rule, final compliance through the use of add-on control equipment shall be no later than March 31, 1985.

1. (6) Seasonal Afterburner Exemption.

   1. (A) The owner or operator of an installation who achieves compliance with this rule through the use of a natural gas-fired afterburner may discontinue operation of the afterburner for a period not longer than six

2. (6) consecutive months beginning October 15 and ending April 15 if—

   1. 1. The afterburner is not used to control

odors; and

1. 2. The discontinuance of operation will

not violate local ordinances.

1. (B) If, in the opinion of the director, the discontinued operation of an afterburner causes a nuisance, the afterburner shall be operated in a manner prescribed by the director.
