9VAC5-40-8400. Test methods and procedures.

A. The provisions of 9VAC5-40-30 (Emission testing) apply.

B. The following EPA test methods shall be used to demonstrate compliance with the heatset web letterpress printing process dryer control device control requirements in 9VAC5-40-8384 B.

1. Reference Method 1 or 1A, as appropriate, shall be used to select the sampling sites.

2. Reference Method 2, 2A, 2C, or 2D, as appropriate, shall be used to determine the velocity and volumetric flow rate of the exhaust stream.

3. Reference Method 3 or 3A, as appropriate, shall be used to determine the concentration of O2 and CO2.

4. Reference Method 4 shall be used to determine moisture content.

5. Reference Methods 18, 25, or 25A shall be used to determine the VOC concentration of the dryer exhaust stream entering and exiting the control device, unless the alternate limit in 9VAC5-40-8384 B 2 is being met, in which case only the VOC concentration of the dryer exhaust control device outlet shall be determined.

6. Reference Method 25A shall be used to determine the dryer exhaust control device inlet and outlet VOC concentrations when the control device outlet concentration is less than 50 parts per million volume (ppmv) VOC as carbon.

7. If the control device is an oxidizer, the combustion chamber temperature or catalyst bed inlet temperature corresponding to destruction efficiencies that meet the requirements of 9VAC5-40-8384 B shall be recorded.

C. The VOC content of as-applied inks, coatings, and cleaning materials shall be determined using Reference Method 24.

1. The analysis of as-supplied materials may be performed by the manufacturer or the supplier. Formulation information from the manufacturer may be used in lieu of Reference Method 24 analysis unless the board or the owner has reason to believe that the formulation information provided by the manufacturer is inaccurate.

2. The owner may use VOC content information provided by the manufacturer or supplier, such as the container label, the product data sheet, or the Safety Data Sheet (SDS) to document the VOC content of the as-supplied material.

3. If cleaning materials are diluted by the owner prior to use, a calculation that combines the as-supplied VOC content information provided by the manufacturer or supplier, the VOC content of the diluent, and the proportions in which they are mixed may be used to make a determination of VOC content of the as-applied cleaning material in lieu of Reference Method 24.

4. The owner shall conduct Reference Method 24 testing of any as-applied cleaning material used for letterpress printing operations at any time at the board's request. The owner shall be prepared to sample as-applied fountain solution or cleaning materials at all times.

D. The VOC composite partial vapor pressure of cleaning solutions shall be determined using the formula provided in 9VAC5-40-8382 C or by an appropriate test method approved by the board.

1. The determination VOC composite partial vapor pressure for as-supplied cleaning solutions may be performed by the manufacturer or the supplier. The determination of as-applied composite vapor pressure based upon the manufacturer's instructions for dilution may be performed by the manufacturer or supplier.

2. The owner may use VOC composite partial vapor pressure information provided by the manufacturer or supplier, such as the container label, the product data sheet, or the Safety Data Sheet (SDS) to document the VOC composite partial vapor pressure of the as-supplied or as-applied cleaning materials.

3. The following provisions apply to the determination of VOC composite partial vapor pressure for cleaning materials that are diluted by the owner prior to use:

a. If the dilution is made according to the manufacturer's instructions, the VOC composite partial vapor pressure for the as-applied cleaning material provided by the manufacturer or supplier may be used.

b. If a dilution is made and an as-applied VOC composite partial vapor pressure has not been provided by the manufacturer or supplier, or if the dilution is not made according to the manufacturer's instructions, then the owner shall determine the VOC composite partial vapor pressure using the calculation method provided in 9VAC5-40-8382 C or by an appropriate test method approved by the board.

4. The owner shall conduct testing of any as-applied cleaning materials used for letterpress printing operations at any time at the board's request. The owner shall be prepared to sample as-applied cleaning materials at all times.
