Environmental Protection Agency (EPA).
The EPA is proposing to partially approve and partially disapprove revisions to the State Implementation Plan (SIP) submitted by the Governor of Wyoming on May 21, 1999. The submittal incorporates revisions to the following sections of the Wyoming Air Quality Standards and Regulations (WAQSR): Section 2 Definitions, Section 4 Sulfur oxides, Section 5 Sulfuric acid mist, Section 8 Ozone, Section 9 Volatile organic compounds, Section 10 Nitrogen oxides, Section 14 Control of particulate emissions, and Section 21 Permit requirements for construction, modification and operation. EPA is proposing to partially disapprove the provisions that allow the Administrator of the Wyoming Air Quality Division to approve alternative test methods to those required in the SIP (sections 2, 4, 5, 10, and 14 of the WAQSR) because such provisions are inconsistent with section 110(i) of the Clean Air Act (Act) and the requirement that SIP provisions can only be modified through revision to the SIP and approval by EPA. The intended effect of this action, once final, is to make federally enforceable those provisions that EPA is approving. EPA is proposing this action under section 110 of the Act.
In the “Rules and Regulations” section of this Federal Register, EPA is acting on 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.
Comments must be received in writing on or before January 22, 2001.
Written comments may be mailed to Richard R. Long, Director, Air and Radiation Program, Mailcode 8P-AR, Environmental Protection Agency, Region VIII, 999 18th Street, Suite 300, Denver, Colorado, 80202.
