Statement of Basis and Purpose




When the Department receives a complaint of persistent perchloroethylene (PERC) odors from occupants of residential and other premises adjacent to or near dry cleaners, an inspection and measurements of PERC are made at the premises. If the level exceeds the nuisance level defined in Health Code §131.17 (“Dry cleaning facilities”), the Department will order the owners of the dry cleaning business and/or the owner of the premises in which the dry cleaner is located to find the cause and abate the nuisance by providing proper exhaust ventilation, adjusting operation of dry cleaning equipment and installing barriers, if necessary, to prevent fumes from escaping.


The Department proposes that the Board amend Health Code §131.17 to reduce the nuisance level for  emissions of PERC vapors found in residential, child-occupied and other occupied buildings emanating from dry cleaning facilities located in the same or adjacent buildings. The amendment would lower the current nuisance level from 100 micrograms per cubic meter (μg/m3) to 30 μg/m3.  The reduction of the nuisance level is based on studies by the US Environmental Protection Administration (EPA), which classifies PERC as “likely to be carcinogenic in humans by all levels of exposure” and a recently revised New York State Department of Health guideline for PERC air levels.[1]


EPA’s rules prohibit using PERC dry cleaning machines in residential buildings after December 21, 2020.[2]   Until then, dry cleaning facilities that use PERC must control emissions in accordance with EPA rules.
