Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11

Affected: IC 13-15; IC 13-17

Sec. 6. (a) Compliance with the add-on control requirements shall be determined by performing emission tests as follows:

1. (1) Run at typical operating conditions and flow rates compatible with scheduled production during any emission testing.

2. (2) The initial emission test shall be performed, within ninety (90) days after the compliance date or within one hundred eighty (180) days after initial startup for new presses. An emission test conducted prior to April 1, 2011, may be accepted if the owner or operator provides records showing that:

   1. (A) the test was conducted in accordance with a testing protocol approved by IDEM;
   2. (B) a U.S. EPA approved emission test method was employed; and
   3. (C) the operation of the press or presses was consistent with the current operating conditions and operating capacity.
3. (3) The negative dryer pressure shall be established during the initial test using an airflow direction indicator, such as a smoke stick or aluminum ribbons, or differential gauge. Continuous dryer air flow monitoring is not required.

4. (4) The test methods and procedures in 326 IAC 8-1-4(d) through 326 IAC 8-1-4(f) shall be followed. If the limit of twenty (20) ppmv is being met, only the VOC concentration of the exit exhaust shall be determined. The following test requirements apply:

   1. (A) To prevent condensation when using 40 CFR 60, Method 25*, the probe should be heated to at least the gas stream temperature, typically close to three hundred fifty (350) degrees Fahrenheit.
   2. (B) To prevent condensation when using 40 CFR 60, Method 25A* when testing heatset web offset presses, the sampling components and flame ionization detector block should be heated to at least the gas stream temperature, typically close to three hundred fifty (350) degrees Fahrenheit.

(b) VOC (alcohol) content of as-applied fountain solution shall be determined by using an accurate hydrometer to measure the alcohol content of the fountain solution. The hydrometer shall have a visual, analog, or digital readout with an accuracy of five-tenths percent (0.5%).

(c) VOC content of as-applied fountain solution or cleaning materials shall be determined in accordance with the following:

1. (1) Analysis by 40 CFR 60, Method 24*.
2. (2) Analytical data derived from a material safety data sheet (MSDS) or equivalent information from the supplier as long as it is based on 40 CFR 60, Method 24*.
3. (3) If diluted prior to use, a material balance calculation that combines 40 CFR 60, Method 24* analytical data or supplier information for the concentrated materials used to prepare the fountain solution or cleaning material and the proportions in which they are mixed to make the as-applied material.

(d) Temperature requirements for refrigeration shall be determined with a thermometer or other temperature detection device capable of reading to five-tenths (0.5) degree Fahrenheit.

(e) The composite partial vapor pressure of a cleaning material shall be determined according to the following:

1. (1) Determine the identity and quantity of each compound in a blended organic solvent using the manufacturer's product formulation data.

2. (2) Determine the vapor pressure of each pure VOC component by using one (1) of the following:

   1. (A) Standard reference texts.
   2. (B) ASTM Method D2879-92*, ASTM International, 100 Barr Harbor Drive, West Conshohocken, Pennsylvania 19428.

3. (3) Calculate the composite partial vapor pressure of the cleaning material by using the following formula:

   Where:	Wi	=	Weight of the "i"th VOC compound, in grams
   	Ww	=	Weight of water, in grams
   	Wc	=	Weight of exempt compound, in grams
   	MWi	=	Molecular weight of the "i"th VOC compound, in g/g-mole
   	MWw	=	Molecular weight of water, in g/g-mole
   	MWc	=	Molecular weight of exempt compound, in g/g-mole
   	PPc	=	VOC composite partial vapor pressure at 20°C (68°F), in mmHg
   	VPi	=	Vapor pressure of the "i"th VOC compound at 20°C (68°F), in mmHg
