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 9VAC5-40-8424 B 2 or C 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 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 9VAC5-40-8424 B or C, as appropriate, shall be recorded.

C. The VOC content of as-applied inks, varnishes and other coatings, fountain solutions, 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 MSDS sheet to document the VOC content of the as-supplied material.

3. If fountain solution or 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 fountain solution or cleaning material in lieu of Reference Method 24.

4. The owner shall conduct Reference Method 24 testing of any as-applied fountain solution or cleaning material used for offset lithographic 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. A thermometer or other temperature detection device capable of reading the temperature of the fountain solution to within 0.5°F shall be used to determine compliance with fountain solution temperature requirements in 9VAC5-40-8424 D.

E. The VOC composite partial vapor pressure of cleaning solutions shall be determined using the formula provided in 9VAC5-40-8422 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 Material Safety Data Sheet (MSDS), 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 9VAC5-40-8422 C.

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

9VAC5-40-8440. Monitoring.

A. The provisions of 9VAC5-40-40 (Monitoring) apply.

B. Periodic monitoring of offset lithographic printing operations shall be conducted as follows:

1. The alcohol concentration of offset lithographic printing process fountain solution shall be monitored with a hydrometer, equipped with temperature correction or with readings adjusted for temperature, and recorded at least once per shift or once per batch, whichever is longer. A standard solution shall be used to calibrate the hydrometer for the type of alcohol used in the fountain.

2. The temperature of refrigerated fountain solution shall be measured at the recirculating tank at least once per operating day.

3. The temperature of a catalytic or thermal oxidation control device shall be monitored at least once every 15 minutes while the printing process is operating, and that temperature shall be recorded by an analog or digital recording device.

b. For a thermal oxidizer, the combustion chamber temperature of the oxidizer shall be monitored and recorded.

4. Catalyst bed material in a catalytic oxidation control device shall be inspected annually for general catalyst condition and any signs of potential catalyst depletion. Sampling and evaluation of the catalyst bed material shall be conducted whenever the results of the inspection indicate signs of potential catalyst depletion or poor catalyst condition based on manufacturer's recommendations, but not less than once per year.

5. If a heatset web offset lithographic printing process is interlocked to ensure that the control device is operating and airflow is present when the printing process is operating, then periodic monitoring of dryer air flow is not required. If no interlock is present, then the printing process dryer air flow shall be verified and recorded once per operating day.
