(a) Administrative Rules of Montana 17.8.309(5)(b) and 17.8.310(3)(e) of the State's rule regulating fuel burning, which were submitted by the Governor on April 14, 1999 and which allow terms of a construction permit to override a requirement that has been approved as part of the SIP, are disapproved. We cannot approve these provisions into the SIP, as it would allow the State to change a SIP requirement through the issuance of a permit. Pursuant to section 110 of the Act, to change a requirement of the SIP, the State must adopt a SIP revision and obtain our approval of the revision.
(b)(1) In 40 CFR 52.1370(c)(51), we incorporated by reference several documents that comprise the East Helena Lead SIP. Sections 52.1370(c)(51)(i)(B) and (C) indicate that certain provisions of the documents that were incorporated by reference were excluded. The excluded provisions of Sec. 52.1370(c)(51)(i)(B) and (C) are disapproved. These provisions are disapproved because they do not entirely conform to the requirement of section 110(a)(2) of the Act that SIP limits must be enforceable, nor to the requirement of section 110(i) that the SIP can be modified only through the SIP revision process. The following phrases, words, or section in exhibit A of the stipulation between the Montana Department of Environmental Quality (MDEQ) and Asarco, adopted by order issued on June 26, 1996 by the Montana Board of Environmental Review (MBER), are disapproved:

(e) In 40 CFR 52.1370(c)(52), we approved portions of the Billings/Laurel Sulfur Dioxide SIP for the limited purpose of strengthening the SIP. Those provisions that we limitedly approved are hereby limitedly disapproved. This limited disapproval does not prevent EPA, citizens, or the State from enforcing the provisions. This paragraph identifies those provisions of the Billings/Laurel SO2 SIP identified in 40 CFR 52.1370(c)(52) that have been limitedly disapproved.
