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 419 to
423 shall control volatile organic

available control techniques and operating practices demonstrating best current
technology, as approved by the department.
