## Abstract

EPA approves a revision to Utah's State Implementation Plan (SIP) for Visibility Protection, as submitted by the Governor with a letter dated July 25, 1996. The revision was adopted by the State in 1993 to address comments received from the 1992 Utah Legislature's Administrative Rules Review Committee regarding the need to remove a visibility policy statement from a regulation format (since it was not a rule). The State responded by deleting the policy statement from the Utah Air Conservation Regulations and adding the text into the Visibility Protection SIP. This submittal was a necessary ``housekeeping'' step to bring the federally approved SIP up-to-date with administrative revisions that took place at the State in 1993.
