Prevention for Federal Class I Areas; Removal of Federally Promulgated Provisions

AGENCY: Environmental Protection Agency (EPA)

ACTION: Proposed rule.

SUMl\fARY: EPA is proposing to remedy an inadvertent omission in the Tennessee

State Implementation Plan (SIP) regarding visibility in 40 CFR 52.2234. EPA approved

Tennessee's visibility rules addressing new source review on July 18, 1996, and a plan

addressing monitoring and reporting of visibility on July 2, 1997. EPA's approval of

these rules neglected to remove the previous federally promulgated provisions from the

Federal Implementation Plan contained in 40 CFR 52.2234. EPA is proposing to correct

this omission in this rulemaking. This action is being taken pursuant to section 110 of the

Clean Air Act. In the Final Rules Section of this Federal Register, EPA is approving the

State's SIP revision as a direct [mal rule without prior proposal because the Agency views

this as a noncontroversialsubmittal and anticipates no adverse comments.
