ABSTRACT

EPA Method 1664 Revision B was published in February 2010 and was included in Table IB as an approved inorganic test procedure for the measurement of oil and grease in the final Method Update Rule published on May 18th, 2012. EPA 1664B is an updated version of EPA 1664A and specifically identifies a list of allowable method modifications and other modifications that are not allowed. Now that laboratories, auditors and regulators are applying the requirements of EPA 1664B, certain clarifications may be needed due to a misunderstanding or misinterpretation of previous EPA 1664A requirements. The author will address a few of the hotter topics with EPA 1664A/B and will also clarify the requirements of the final decision on an alternative Oil and Grease method published on March 6, 2013.
