NOTICE: PROPOSED RULES

ACTION: Air quality implementation plans; approval and promulgation; various States:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Approval and Promulgation of Air Quality Implementation Plans; State of South Dakota; Revisions to the Administrative Rules of South Dakota and New Source Performance Standards Delegation

DATES: Written comments must be received on or before June 9, 2004.

DOCUMENT SUMMARY: EPA is proposing to take direct final action approving State Implementation Plan (SIP) revisions submitted by the State of South Dakota on September 12, 2003. The September 12, 2003 submittal revises the Administrative Rules of South Dakota, Air Pollution Control Program, by modifying the chapters pertaining to definitions, operating permits for minor sources, new source review and performance testing. In addition, the State made revisions to the Prevention of Significant Deterioration program, which has been delegated to the State. The intended effect of this action is to make these revisions federally enforceable. We are also announcing that on October 31, 2003, we updated the delegation of authority for the implementation and enforcement of the New Source Performance Standards to the State of South Dakota. These actions are being taken under sections 110 and 111 of the Clean Air Act.

In the ``Rules and Regulations'' section of this 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 SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

SUMMARY: South Dakota,
