SCAQMD Rules Limiting Use of Cleaner Aerosols
On October 8, 1999, SCAQMD amended its Rule 1171 to limit aerosols used for cleaning purposes in the shop area to 160 oz.(about 10-11 cans) per day per facility regardless of the facility size. SCAQMD considers cleaners subject to the 160 oz. limit to be any aerosol with more than 50 g/L of volatile organic compounds (VOC’s). By definition, aerosols with less than 50 g/l of VOC are exempt from all provisions of the rule and do not trigger the 160oz. per day limit. And so are 100% acetone based cleaners as acetone is a compliant chemical not subject to VOC requirements.
