The EPA published in the Federal Register on June 12, 2001 and June 18, 2001 several documents that, among other things, approved updates to Montana's State Implementation Plan (SIP). In the June 12, 2001, rule, which approved the State's Emergency Episode Avoidance Plan and Cascades County's Local Regulation Chapter 7, Open Burning, EPA inadvertently omitted a sentence from the Administrative Requirements section of the document. EPA is correcting the Administrative Requirements section with this document. In the June 18, 2001, rule, which partially approved and partially disapproved the East Helena Lead (Pb) SIP, EPA inadvertently referenced an incorrect date in the preamble and inadvertently failed to promulgate regulatory text for those portions of the plan we disapproved, and to indicate that we determined that the East Helena Pb nonattainment area had attained the Pb NAAQS. In addition, in the regulatory text that was promulgated in the June 18, 2001 document, EPA inadvertently failed to indicate that the partially approved Pb SIP superseded the previously approved Pb SIP. Also, quotation marks were placed in the wrong location in the June 18, 2001 regulatory text. EPA is correcting the date in the preamble, promulgating the regulatory text for the disapproved provisions of the plan, correcting the promulgated regulatory text to indicate that the partially approved Pb SIP supercedes the previously approved Pb SIP, and correcting the location of quotation marks in the promulgated regulatory text with this document.
