The Industrial Cleaning Solvent Control Technique Guidelines (CTGs) regulate the VOC content of solvents used in cleaning coatings manufacturing operations. The American Coatings Association is actively working with Texas, Ohio, Indiana, Illinois, Maryland, Connecticut, Wisconsin, New Hampshire, Delaware, Virginia, and the District of Columbia to exempt solvents used for cleaning in industrial coatings manufacturing from the stringent CTG limit of 50 g/l. The overly stringent 50 g/l limit that the states are adopting generally only allows the use of exempt solvents like acetone, which may not be effective in cleaning coatings manufacturing equipment.
In Texas, ACA has engaged pre-adoption of the CTG and can hopefully convince Texas to exempt coatings manufacturing solvent cleaning from the stringent CTG limits. ACA's Texas Paint Council attended a stakeholder meeting in Austin on Dec 1.
Where states are not willing to exempt coatings manufacturing solvent cleaning outright, ACA is advocating more reasonable standards modeled on the Bay Area Air Quality Management District that U.S. EPA discussed in the Industrial Cleaning Solvent CTG.
