          - 40 CFR Part 52
          - [R07-OAR-2004-IA-0004; FRL-7833-8]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

EPA is proposing to approve a revision to the Iowa state implementation plan (SIP) for the purpose of revising open burning rules. This revision includes a provision that allows the Iowa Department of Natural Resources to require the submittal of additional information when a variance from open burning rules is requested, reemphasizes the state's obligation to protect the National Ambient Air Quality Standards (NAAQS) with regard to open burning, clarifies National Emissions Standards for Hazardous Air Pollutants (NESHAP) guidance for disaster rubbish, updates guidance for training fires, and provides clarification to the existing open burning rules covering agricultural structures.

# DATES:

Comments on this proposed action must be received in writing by December 3, 2004.

# ADDRESSES:

                        Comments may be mailed to Heather Hamilton, Environmental Protection Agency, Air Planning and Development Branch, 901 North 5th Street, Kansas City, Kansas 66101. Comments may also be submitted electronically or through hand delivery/courier; please follow the detailed instructions in the Addresses section of the direct final rule which is located in the rules section of this                         **Federal Register**                        .

# SUPPLEMENTARY INFORMATION:

                    In the final rules section of the                     **Federal Register**                    , EPA is approving the state's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no relevant adverse comments to this action. 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 action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the rules section of this                     **Federal Register**                    .
