Part 60 Equipment Compliance Guidelines

Unlike 40 CFR 75, 40 CFR 60 does not address recertification, diagnostic testing, or temporary analyzer replacements. CiSCO consulted the EPA about the required testing for CEMS subject to 40 CFR 60 after repairs and replacements. The EPA holds the position that the state or local agency should determine what testing is required because they are responsible for enforcing 40 CFR 60. As a result, CiSCO contacted each state to understand their testing requirements following CEMS component repairs and replacements. The table below contains the guidance provided by each state’s regulatory department and various local agencies.
