Section 424.03. Process lines emitting organic compounds.

 

(1)   Exemptions.

(a) This section applies to all process lines which emit organic compounds, solvents or mixtures, with the following exceptions:

1. Process lines outside the Southeastern Wisconsin Intrastate AQCR on which construction or modification commenced on or before April 1, 1972.

2. Organic compound-water separation systems that process 757 liters (200 gallons) per day or less.

3. Enclosed paint spraying operations from which volatile organic compound emissions are never greater than 13.6 kilograms (30 pounds) in any day.

4. All other process lines from which volatile organic compound emissions are never greater than 6.8 kilograms (15 pounds) in any day.

(b) Where process lines are subject to emission limitations listed elsewhere in chs. NR 419 to 423 , the requirements of this section shall apply in accord with the provisions of s. NR 425.03 (7) (b) .

(c) This section does not apply to any individual cold cleaning, batch vapor degreasing, or conveyorized degreasing operation that is subject to ch. NR 469 .

(2)   Emission limitations. Process lines to which this section applies shall meet the following emission limitations:

(a) Process lines on which construction or modification commenced before August 1, 1979, shall control emissions of photochemically reactive organic compounds by 85%.

(b) Process lines on which construction or modification commenced on or after August 1, 1979, and which are not subject to emission limitations listed elsewhere in chs. NR 419 to 423 shall control volatile organic compound emissions by at least 85%.

(c) Where 85% control as required under either par. (a) or (b) has been demonstrated to be technologically infeasible for a specific process line, the owner or operator shall use the latest available control techniques and operating practices demonstrating best current technology, as approved by the department.

(3)   Election. Surface coating and printing processes subject to the requirements of this section may instead elect, with the approval of the department, to meet the emission limitations of ss. NR 422.01 to 422.155 , notwithstanding ss. NR 422.03 (1) or (3) and 425.03 , provided that all of the following requirements are met:

(a) The process line meets the specific applicability requirements of ss. NR 422.05 to 422.155 .

(b) The owner or operator submits a written request to the department. Written requests under this paragraph shall include, in the case of sources constructed prior to August 1, 1979, a schedule for meeting the requirements of ss. NR 422.01 to 422.155 .
