(A) a flow rate of 20,000 actual cubic feet per minute (acfm) and the greater of six feet above the peak of the manufacturing building or 25 feet above ground level; or

(B) a flow rate of 15,000 acfm and the greater of six feet above the peak of the manufacturing building or 30 feet above ground level.

(3) No more than 1,000 pounds per year of resin shall be used outdoors.

(4) If annual resin usage is less than 1,000 pounds, a facility is exempt from all requirements of this exemption except recordkeeping (see 113(a)(2)).

All stacks shall discharge vertically to the atmosphere with no restrictions or obstructions to flow. Each stack shall meet one of the following minimum requirements:

(A) a flow rate of 20,000 acfm and the greater of six feet above the peak of the manufacturing building or 25 feet above ground level; or

(B) a flow rate of 15,000 acfm and the greater of six feet above the peak of the manufacturing building or 30 feet above ground level.

(3) No more than 3,000 pounds per year of resin shall be used outdoors.
