This regulation also shall apply to any installation which does not have an allowable VOC 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 (250) kg/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.
3. (2) Definitions of certain terms specified in this regulation may be found in 10 CSR 10- 6.020.

4. (3) General Provisions.

   1. (A) No person shall emit to the atmosphere any VOC from the application of automotive underbody deadeners in excess of the emission limit in section (4).
   2. (B) The emission limit contained in section
5. (4) shall be based on a daily weighted average of all deadeners delivered to the coating applicator.
6. (4) Emission Limit and Compliance Date. Application Compliance Process Emission Limit Date General Motors 2.2 #VOC/Gal. 12/31/87 Auto Underbody of Deadener Deadeners (minus water)

7. (5) Recordkeeping.

   1. (A) The owner or operator of a deadener application operation covered by this regulation must maintain daily records of the composition and amount of deadener used, the amount of solvent used, the amount of cleanup solvent used and discarded and any other information necessary to determine compliance regulation this regulation or to quantify VOC emissions.

8. (6) Compliance Method. Compliance with this regulation shall be demonstrated using the test method referenced at 10 CSR 10- 6.030(14)(C) to determine deadener composition. The deadener manufacturer’s formulation data may be used to demonstrate compliance, but only after confirmation by the test method previously referenced.
