What Type of Solvent(s) Does Your Business Use?

Are you familiar with the solvent(s) being utilized within your cold cleaner degreaser operation?

Starting January 1, 2015, all persons who sell or purchase solvents for use in a cold cleaner degreaser operation will be required to keep the records specified within 326 IAC 8-3-8(c) including the true vapor pressure of the solvent. (The true vapor pressure is defined as “the equilibrium pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, “Evaporation Loss from Floating Roof Tanks,” 1962.”) A purchasing invoice or a copy of the manufacturer’s recommendation for the solvents utilized may include most of the required records.

In addition to speaking with Compliance and Technical Assistance Program (CTAP) staff, you may also visit the newly created Degreasing Operations webpage, for information on how to comply with state and federal regulations concerning degreasing, as well as tips to consider when evaluating solvent alternatives.
