The Ozone Transport Commission (OTC), an organization of states in the Northeast/Mid-Atlantic region created under the Federal Clean Air Act, is charged with achieving better air quality, in part by decreasing Volatile Organic Compounds (VOCs). On March 12, 2012, the OTC approved a model rule for solvent degreasing that is strongly influenced by Southern California regulations, notably the South Coast Air Quality Management District (SCAQMD). The VOC limit in the model rule is 25 g/L. To use higher VOC limits, “airless” cleaning systems would be required.
The next step is the rule-making processes; the model rule can be adopted or adapted by individual states. For example, Delaware is expected to start the rule-making process at the beginning of this year.
