Document Number: E8-18191
Type: Proposed Rule
Date: 2008-08-07
Agency: Environmental Protection Agency
EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia. This SIP revision pertains to the requirements in meeting the reasonably available control technology (RACT) under the 8-hour ozone national ambient air quality standard (NAAQS). These requirements are based on: Certification that previously adopted RACT controls in Virginia's SIP that were approved by EPA under the 1-hour ozone NAAQS are based on the currently available technically and economically feasible controls, and that they continue to represent RACT for the 8-hour implementation purposes; a negative declaration demonstrating that no facilities exist in Stafford County for the applicable control technology guideline (CTG) categories; and new RACT determinations. This action is being taken under the Clean Air Act (CAA).

Document Number: E8-16269
Type: Proposed Rule
Date: 2008-08-07
Agency: Environmental Protection Agency
EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Colorado on August 1, 2007. These revisions establish affirmative defense provisions for source owners and operators for excess emissions during periods of malfunction. The affirmative defense provisions are contained in the State of Colorado's Common Provisions regulation. The intended effect of this action is to approve only those portions of Colorado's Common Provisions regulation submitted on August 1, 2007 that relate to the affirmative defense for malfunctions. This action is being taken under section 110 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 non- controversial 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.
