Rule 466 (Solvent Cleaning)
Document Type
NOE - Notice of Exemption
Document Description
Rule 466 sets limits on the maximum VOC content allowed for solvents used in surface preparation, product cleaning, and cleaning of equipment and tools. Rule 466 was amended in 2008 to reduce the allowable VOC content of solvents used in various cleaning applications. At the same time, a new limit was added for the VOC content of cleaning solvents used to sterilize food manufacturing equipment. Subsequent to the 2008 adoption, a food processing company presented information demonstrating that the limit was infeasible for their nut processing plant. The company uses isopropanol solution to prevent bacterial growth along the nuts processing line. There are no low VOC products currently available that can meet the sterilization standards to protect against salmonella contamination. The amendments to Rule 466 will exempt dry food processors from the VOC limit for sterilization fluids.
