E7-19832. Approval and Promulgation of Air Quality Implementation Plans; State of South Dakota; Revisions to the Administrative Rules of South Dakota

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of South Dakota on August 8, 2006. The August 8, 2006 submittal revises the Administrative Rules of South Dakota, Air Pollution Control Program, by modifying the chapters pertaining to definitions, ambient air quality, air quality episodes, operating permits for minor sources, performance testing, control of visible emissions, and continuous emission monitoring systems. The intended effect of this action is to make these revisions federally enforceable. We are also announcing that on July 19, 2007, 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.

DATES:

Written comments must be received on or before November 13, 2007.
