(2) Emissions From Nitric Acid Plants
(a) Existing Nitric Acid Plants

After July 1, 1975, no person shall cause, suffer, allow, or permit the emission into the air of nitrogen oxides from any nitric acid plant under construction or in operation prior to April 3, 1972, which are:

1. In excess of 5.5 lbs per ton of acid produced, maximum 2 hour average, expressed as NO2; or
2. 400 ppm (0.04% by volume dry basis) of nitrogen oxides, measured as NO2, whichever is the more restrictive.
(3) New and Existing Cotton Gins
(a) For the purpose of this paragraph, the following definitions apply:
1. "Cotton Gin" means any facility or plant which removes seed, lint, and trash from raw cotton and bales the lint cotton for further processing. All individual pieces of equipment located at a cotton gin shall be considered as being a single process emission source.
2. "Cotton Gin Site or Gin Site" means the land upon which a cotton gin is located and all contiguous land having an identical ownership.
3. "High Efficiency Cyclone" means any cyclone type collector of the 2D-2D or 1D-3D configuration. The 2D-2D design for small diameter cyclones is set forth in Agricultural Handbook 503, U.S. Dept. of Agriculture, Cotton Ginners Handbook, 1977 Edition, pages 81-84. The 1D-3D design for small diameter cyclones is the Texas A § M University long-cone cyclone design. Design specifics of this type of cyclone are set forth in Figure 6 of the article titled, "Air Utilization", by E.P. Columbus, which was presented at the Cotton Ginners Shortcourse which was held on July 27-31, 1987 at Stoneville, Mississippi.
4. "Low Pressure Exhausts" means the exhaust air systems at a cotton gin which handles air from the cotton lint handling system and battery condenser.
5. "High Pressure Exhausts" means all other exhaust air systems located at a cotton gin which are not defined as "low pressure exhausts".
6. "Dust House" means a gravity settling chamber utilized for the control of particulate emissions from a cotton gin and meeting the specifications set forth in Agriculture Handbook 260, U.S. Dept. of Agriculture, Handbook for Cotton Ginners, 1964 Edition, page 93.
(b) The following conditions apply to owners and operators of cotton gins subject to the provisions of this paragraph:
1. Reserved.
2. The owner or operator of a cotton gin which was in operation or under construction on or prior to July 16, 1990, shall meet the standards set forth in Table 4 of rule 1200-03-07-.08 no later than July 1, 1991.
3. The owner or operator of a cotton gin for which construction begins after July 16, 1990 shall meet the standards set forth in Table 4 at the time the cotton gin commences operation.
4. In lieu of demonstrating compliance with the applicable emission standard contained in Table 4 of this rule the following control devices may be utilized:
(i) for emission control from low pressure exhausts, the use of screens with a mesh size of 80 by 80 or finer, or the use of perforated condenser drums with holes not exceeding .045 inches in diameter, or the use of a dust house.
(ii) for emission control from high pressure exhausts the use of high efficiency cyclones shall be deemed as demonstrating compliance.
5. If compliance with the emission standard specified in Table 4 is required, then the testing methodology to be utilized shall be that specified in Chapter 2 of the Department of Health and Environment's Source Sampling Manual (dated December 10, 1987).
6. Effective July 1, 1991, the burning of cotton gin waste at the gin site in a wigwam or any other type of enclosed burner shall be prohibited.
(c) The allowable particulate emission standards for new and existing cotton gins shall be determined by Table 4.

TABLE 4 ALLOWABLE RATE OF PARTICULATE EMISSIONS BASED ON PROCESS WEIGHT RATE FOR NEW AND EXISTING COTTON GINS

Process Weight Rate Rate of Emission Process Weight Rate Rate of Emission
Lb/Hr Lb/Hr Lb/Hr Lb/Hr
1,000 1.6 9,000 13.7
1,500 2.4 10,000 15.2
2,000 3.1 12,000 18.2
2,500 3.9 14,000 21.2
3,000 4.7 16,000 24.2
3,500 5.4 18,000 27.2
4,000 6.2 20,000 30.1
5,000 7.7 30,000 44.9
6,000 9.2 40,000 59.7
7,000 10.7 50,000 64.0
8,000 12.2 60,000 or more 67.4

The allowable emission rate for a cotton gin with process weight rates intermediate to those shown in Table 4 shall be determined by linear interpolation.

(4) New and existing Kraft Mills.

The owner or operator of a kraft mill on which construction begins after January 1, 1973, shall meet the standards listed in subparagraphs (a), (b), and (c) of this paragraph at the time of operation of such mill commences. After August 9, 1973, no person shall cause, suffer, allow or permit particulate emissions from a kraft mill under construction or operation prior to September 11, 1980, in excess of the standard chosen in 1200-03-07-.02(1) or 1200-03-07-.02(2) provided, however, that after July 1, 1977, said emissions are as follows:

(a) Particulate matter from all recovery stacks shall not exceed three pounds per ton of equivalent air-dried kraft pulp.
(b) Particulate matter from all lime kilns shall not exceed one pound per ton of equivalent air dried kraft pulp.
(c) Particulate matter from all smelt tanks shall not exceed on-half pound per ton of equivalent air dried kraft pulp.
(5) Existing Asphalt Plants.

After August 9, 1973, no person shall cause, suffer, allow or permit the discharge of particulate emissions from any asphalt plant under construction or in operation prior to April 3, 1972, in excess of the standard selected in accordance with the provisions of 1200-03-07-.02(1) or 1200-03-07-.02(2). It is expressly provided that no later than July 1, 1975, these emissions shall not be in excess of the standards set forth in Table 1 of chapter 1200-03-07, entitled "Existing Process Emission Sources: Allowable Rate of Emission Based on Process Weight Rate." It is further stipulated that after that date, the rate of emission for existing asphalt plants with a process weight rate in excess of 200,000 pounds (100 tons) per hour shall not exceed 51.2 pounds per hour. Asphalt plants which are relocated more than 1.0 km from the previous position and did not receive a construction permit prior to November 6, 1988, shall not be allowed to emit more than the greater of the actual emissions at its previous location or the allowable emissions for a new asphalt plant.
