At the October 4 hearing, the Utah Air Quality Board gave final approval to Change in Proposed Rule R307-335-Degreasing and New Rule R307-304-Solvent Cleaning (See Rules Here).  In brief, the new rules require anyone using cleaning solvents in excess of 55 gallons/year must either change to a low VOC solvent or install a closed recovery system to capture VOC emissions from the solvent's use.  The Board did allow some exceptions/exemptions to this rule that may apply to your company, so please read the rule carefully.  The rules become effective September 1, 2018.
