Click the Safety Data Sheet link to get more detailed information on a solvent. After December 21, 2020, a facility located in a building that has at least one residence can no longer use perc.

*Machines using only water or liquid carbon dioxide are not regulated by Part 232 (leaves DEC).

To request approval of a solvent, submit information as specified in Part 232-3 (leaves DEC). Only manufacturers or their distributers can request approval. A preliminary decision is issued within 90 days of receipt of a complete submission. Solvents proposed for approval will appear in the Environmental Notice Bulletin. If no substantive negative comments are received, the solvent will approved. Any solvent changing its chemical formulation must undergo the approval process again before use in NYS.

NOTE: None of the above approved alternative solvents is a drop-in replacement for perc. Contact the solvent manufacturer for the required dry cleaning machine specifications for the approved alternative solvent under consideration.
