The American Coatings Association says many states have established or are in the process of adopting industrial solvent cleaning regulations that could impact coatings, ink, adhesive and resin manufacturing operations. In particular, these rules could impact the type of solvents that are used to clean process equipment, tanks, lines, etc.
Cleaning solvents would need to meet a volatile organic compound (VOC) limit of 50 g/L, which means that current cleaning solvents would need to be disposed of and exempt solvents (e.g., acetone) be used their place.
In general, these rules apply in ozone non-attainment areas to facilities that have at least 15 lb/day of solvent cleaning VOC emissions (uncontrolled). States that have either adopted or are very close to adopting rules include Ohio, Indiana, Illinois, Maryland, Connecticut, Wisconsin, New Hampshire, the District of Columbia, Delaware, Texas, Missouri and North Carolina.
