Events Reforms Act of 2012''.

SEC. 2. AMENDMENTS TO THE EXCEPTIONAL EVENT PROVISION OF THE CLEAN AIR 
              ACT.

    (a) Exceptional Event Demonstration.--Section 319(b)(3)(B)(iv) of 
the Clean Air Act (42 U.S.C. 7619(b)(3)(B)(iv)) is amended by striking 
``to petition the Administrator to'' and inserting ``to submit a 
petition (in this section referred to as an `exceptional event 
demonstration') to the Administrator to''.
    (b) Criteria.--Section 319(b)(3) of the Clean Air Act (42 U.S.C. 
7619(b)(3)) is amended by adding at the end the following:
                    ``(C) Criteria for determination of exceptional 
                event demonstration.--The criteria for evidence, 
                analyses, and documentation applicable to approval or 
                disapproval of an exceptional event demonstration under 
                the regulations under this section shall be stated with 
                specificity in order to minimize the discretion of the 
                Administrator in approving or disapproving such

                criteria in conjunction with input from the States. 
                Such criteria shall reflect the varying level of 
                technical expertise and resources available in State 
                and local agencies and the varying availability of 
                meteorological and other monitoring data in rural 
                areas, and may vary with respect to different regions. 
                In developing such criteria, the Administrator shall 
                also consider use of an expedited or streamlined 
                approval process and conditions under which exceptional 
                event demonstrations may be suitable for such a 
                process.''.

                        later than 90 days after submission of an 
                        exceptional event demonstration, the 
                        Administrator shall approve, disapprove, or 
                        request additional information from a State 
                        regarding such an exceptional event 
                        demonstration. If the Administrator does not 
                        take any action with respect to an exceptional 
                        event demonstration within such 90-day period,

                            ``(ii) Deadline if additional information

                        additional information from a State regarding 
                        an exceptional event demonstration under clause 
                        (i), not later than 90 days after the 
                        submission of such additional information, the 
                        Administrator shall approve or disapprove such 
                        demonstration. If the Administrator does not 
                        approve or disapprove such a demonstration for 
                        which additional information is submitted 
                        within such 90-day period, such demonstration

                disapproval of an exceptional event demonstration be 
                based on a preponderance of the evidence. In making any 
                such determination, the Administrator shall accord 
                substantial deference to the findings of the State 
                exceptional event demonstration and may develop and use 
                analyses and consider evidence not provided by such 
                exceptional event demonstration.''.
    (e) Appeals.--Section 319(b)(3) of the Clean Air Act (42 U.S.C. 
7619(b)(3)) is further amended by adding at the end the following:
                    ``(F) Appeals.--Approval or disapproval by the 
                Administrator of an exceptional event demonstration 
                shall be considered final action subject to judicial 
                review under section 307(b).''.

Summary: Commonsense Legislative Exceptional Events Reforms Act of 2012 - Amends the Clean Air Act to revise provisions concerning state petitions to exclude air quality monitoring data influenced by exceptional events from determinations of exceedences or violations of the national ambient air quality standards by requiring criteria used in determining if there has been a demonstration of an exceptional event to be stated with specificity in order to minimize the discretion of the Administrator in approving or disapproving such demonstration. Requires: (1) the Administrator to develop such criteria in conjunction with input from states, and (2) such criteria to reflect the technical expertise and resources available in state and local agencies and the availability of meteorological and other monitoring data in rural areas. Authorizes such criteria to vary with respect to different regions. Requires the Administrator, in developing such criteria, to consider using an expedited or streamlined approval process and conditions under which such demonstrations may be suitable for such process. Requires the Administrator: (1) to approve or disapprove an exceptional event demonstration within 90 days of such demonstration. Or (2) if the Administrator requests additional information from a state regarding such demonstration, to approve or disapprove such demonstration within 90 days of submission of such information. Considers such demonstrations to be approved if the Administrator does not take action within such time frames. Requires: (1) such approval or disapproval to be based on a preponderance of the evidence, and (2) the Administrator to accord substantial deference to state findings on such demonstration. Authorizes the Administrator to develop and use analyses and consider evidence not provided by such demonstration. Considers such approval or disapproval to be final action subject to judicial review. Requires the Administrator to revise regulations concerning air quality monitoring data influenced by exceptional events to meet the requirements of this Act within 180 days of this Act's enactment.
