ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IA 048-1048b; FRL-6113-2]

Approval and Promulgation of Implementation Plans and Approval

Under Section 112(l); State of Iowa

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The EPA proposes to approve the State Implementation Plan

(SIP) revisions submitted by the state of Iowa. These revisions are

necessary to meet the requirements of the Clean Air Act (Act) and the

Code of Federal Regulations and to improve the state's permitting

program. 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.

In the final rules section of the Federal Register, the 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 the 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rule will be withdrawn and all public comments received will be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. The

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

July 27, 1998.

ADDRESSES: Comments may be mailed to Wayne 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.

Authority: 42 U.S.C. 7401 et seq.

Dated: May 26, 1998.

William Rice,

Acting Regional Administrator, Region VII.
