Approval and Promulgation of Air Quality Implementation Plans; Montana; State Implementation Plan Correction

On September 19, 1975, we approved the East Helena Sulfur Dioxide (SO 2 ) State Implementation Plan (SIP). Additionally, on May 1, 1984, we approved revisions to the East Helena SO 2 SIP. Finally, on January 27, 1995, we approved additional revisions to the East Helena SO 2 SIP. The East Helena SO 2 SIP approved on January 27, 1995, superceded the East Helena SO 2 SIP approved on September 19, 1975, and terminated the East Helena SO 2 SIP approved on May 1, 1984. However, when we approved the SIP revision on January 27, 1995, we did not indicate that it superceded and terminated earlier SIP approvals. EPA is making a correction to the regulatory language to clarify that the earlier East Helena SO 2 SIP revisions have been superceded or terminated by the East Helena SO 2 SIP approved on January 27, 1995.
