# AGENCY:

# ACTION:

Proposed rule.

# SUMMARY:

                        EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the state of Iowa for the purpose of establishing guidelines to identify stationary sources of air pollution potentially subject to Best Available Retrofit Technology (BART) emission control requirements. Owners and operators of stationary sources meeting the eligibility criteria will be required to submit source identification and emission unit description information to the state by September 1, 2005. BART-eligibility information is to be submitted on Iowa Department of Natural Resources (IDNR) form 542-8125 that lists facility information and emission unit identification and description. Annual emission totals in tons-per-year (potential) for PM10, NOX, SO2                         and VOCs are also required.

# 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adverse comments, the direct                           ( print page 53975)                        final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action.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**                    .
