Rule 5-253-17, Industrial Cleaning Solvents, applies to any facility that purchases for use at least 855 gallons of cleaning solvents, in aggregate, per rolling 12-month period. There is an exemption to this rule for screen printing operations. Cleaning of screen printing equipment is exempt as long as the cleaning solvent used has an as-applied VOC content that does not exceed 500 grams per liter or 4.2 pounds per gallon.
Cleaning activities associated with offset lithographic and letterpress printing are also exempt from the provisions of this rule.
If your facility must comply, then products containing no more than 50 grams per liter (0.42 lbs/gal), as applied or those with a vapor pressure no greater than 8 mmHg at 20°C can be used.
