Today, EPA confirmed that revisions to Performance Specification 1 (PS-1) are put on hold for at least 60 days [Federal Register (February 6, 2001)]. EPA takes this action in accordance with the January 24th memorandum from the Assistant to the President and Chief of Staff titled, "Regulatory Review Plan."
EPA finalized revisions to PS-1 on August 10, 2000. The revisions to PS-1, which apply to continuous opacity monitors, were to be effective 180 days thereafter (i.e., February 6, 2001). The revisions to PS-1 were intended to clarify and update requirements for source owner/operators who are required by EPA to install and operate continuous opacity monitors. The revisions also update design and performance validation requirements for continuous opacity monitoring systems. Fortunately, PS-1 applies only to new and/or relocated continuous opacity monitoring systems.
