Sec. 4. (a) This section applies to sources manufacturing pneumatic rubber, passenger type tires on a mass production basis. "Passenger type tire" means agricultural, airplane, industrial, mobile home, light and medium duty truck, and passenger vehicle tires with a bead diameter up to twenty (20) inches and cross section dimensions up to twelve and eight-tenths (12.8) inches.

(b) This section does not apply to the production of specialty tires for antique or other vehicles when produced on an irregular basis or with short production runs. If normal production line equipment is used for such limited runs, then any control equipment installed for such equipment shall be used during the limited runs.

(c) This section applies to the following individual types of facilities:

1. (1) Undertread cementing, which is the application of a solvent based cement to the underside of a tire tread. This shall not include application of cement to precured tread to be used for recapping of used tires.
2. (2) Bead dipping, which is the dipping of an assembled tire bead into a solvent based cement.
3. (3) Tread end cementing, which is the application of a solvent based cement to the tire tread ends.
4. (4) Green tire spraying, which is the spraying of green tires, both inside and outside, with release compounds which help remove air from the tire during molding and prevent the tire from sticking to the mold after curing.

(d) The following facilities subject to this section shall comply with subsections (e) through (f) no later than December 31, 1991:

1. (1) Facilities located in Clark, Elkhart, Floyd, Lake, Marion, Porter, and St. Joseph Counties.
2. (2) Facilities, which commenced construction between January 1, 1980, and January 20, 1983, located in any county.

(e) The owner or operator of an undertread cementing, tread end cementing, or bead dipping operation shall install and operate a capture system in conjunction with a control device which shall achieve an overall control efficiency of:

1. (1) eighty percent (80%) for carbon adsorption systems;
2. (2) seventy-five percent (75%) for incineration systems; or
3. (3) eighty percent (80%) for alternative volatile organic compound emission reduction systems approved by the commissioner.

(f) The owner or operator of a green tire spraying operation shall meet one (1) of the following requirements:

1. (1) Substitute water-based sprays for the normal solvent-based mold release compound. A water-based spray may contain up to ten percent (10%) organic solvents.

2. (2) Install and operate a capture system in conjunction with a control device which shall achieve an overall control efficiency of:

   1. (A) eighty-five percent (85%) for carbon adsorption systems;
   2. (B) eighty percent (80%) for incineration systems; or
   3. (C) eighty-five percent (85%) for alternative volatile organic compound emission reduction systems approved by the commissioner.

(g) Any alternative organic compound emission reduction system approved by the commissioner, as provided in this section, shall be submitted to the U.S. EPA as a SIP revision.
