[Federal Register: May 13, 1999 (Volume 64, Number 92)] [Proposed Rules] [Page 25855] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr13my99-21] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 52 [IA 069-1069b; FRL-6340-4] Approval and Promulgation of Implementation Plans and Approval Under Section 112(l); State of Iowa AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) revisions submitted by the state of Iowa on December 11, 1998, and January 29, 1999. These revisions consist of updates to Iowa Administrative Code, Chapters 20, 22, 23, 25, and 28. These revisions will strengthen the SIP with respect to attainment and maintenance of established air quality standards and with respect to control of hazardous air pollutants. Approval of this SIP revision will make these rule revisions Federally enforceable. In the final rules section of the Federal Register, EPA is approving the state's SIP revisions as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no relevant adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this document. Any parties interested in commenting on this document should do so at this time. DATES: Comments on this proposed rule must be received in writing by June 14, 1999. ADDRESSES: Comments may be mailed to Wayne A. Kaiser, Environmental Protection Agency, Air Planning and Development Branch, 726 Minnesota Avenue, Kansas City, Kansas 66101. FOR FURTHER INFORMATION CONTACT: Wayne Kaiser at (913) 551-7603. SUPPLEMENTARY INFORMATION: See the information provided in the direct final rule which is located in the rules section of the Federal Register. Dated: April 28, 1999.
