**SUPPLEMENTARY INFORMATION :**  In the Final Rules section of this Federal Register , EPA is approving the State’s SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should 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. For additional information, see the direct final rule which is located in the Rules section of this Federal Register

**Approval and Promulgation of Air Quality Implementation Plans; State of**  **Delaware; Regional Haze State Implementation Plan** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve a revision to the Delaware State Implementation Plan (SIP) submitted by the State of Delaware through the Delaware Department of Natural Resources and Environmental Control (DNREC) on September 25, 2008 that addresses regional haze for the first implementation period. This revision addresses the requirements of the Clean Air Act (CAA) and EPA’s rules that require states to prevent any future, and remedy any existing, anthropogenic impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ‘‘regional haze
program’’). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing to determine that the Regional Haze plan submitted by Delaware satisfies the requirements of the CAA. EPA is taking this action pursuant to those provisions of the CAA. EPA is also proposing to approve this revision as meeting the requirements of 110(a)(2)(D)(i)(II) and 110(a)(2)(J), relating to visibility protection for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) and the 1997 and 2006 fine particulate matter (PM 2.5 ) NAAQS.
