Environmental Protection Agency (EPA).
Direct final rule.
Currently the ozone monitoring season for Idaho is April through October. Based on the ozone monitoring season in adjacent states with similar climatology, and analysis of existing ozone monitoring data collected in Boise, EPA is approving a change in the ozone monitoring season for Idaho to the months of May through September.
This direct final rule is effective October 29, 2004, unless EPA receives adverse comments by September 29, 2004. If relevant adverse comment is received, EPA will publish a timely withdrawal of the rule in the Federal Register informing the public that the rule will not take effect.

Instructions: Direct your comments to Docket ID No. ID-04-003. EPA's policy is that all comments received will be included in the public docket without change, including any personal information provided, unless the comment includes information claimed to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Do not submit information that you consider to be CBI or otherwise protected through regulations.gov, or e-mail. The Federal regulations.gov Web site is an “anonymous access” system, which means EPA will not know your identity or contact information unless you provide it in the body of your comment.

I. General Information
A. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting Confidential Business Information (CBI). Do not submit this information to EPA through regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then identify electronically within the disk or CD-ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 Code of Federal Regulations (CFR) part 2.
2. Tips for Preparing Your Comments. When submitting comments, remember to:
i. Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number).
ii. Follow directions—The Agency may ask you to respond to specific questions or organize comments by referencing a CFR part or section number.
iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information and/or data that you used.
v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.
vi. Provide specific examples to illustrate your concerns, and suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.
viii. Make sure to submit your comments by the comment period deadline identified.
II. Purpose of This Action
The purpose of this action is to change the ozone monitoring season in Idaho from April through October to May through September.
III. Justification for This Action
Currently the ozone monitoring season for Idaho, as identified in 40 CFR 58, Appendix D, section 2.5, is April through October. The EPA guidance titled, “Guideline for Selecting and Modifying the Ozone Monitoring Season Based on an 8-Hour Ozone Standard” states that the ozone season should extend for months for which the maximum 8-hour ozone reading reaches the 8-hour standard (0.08 ppm). The guideline also states that the most recent six years of data should be used to prepare a histogram of maximum ozone concentrations by month to compare to the 8-hour standard. However, if a state which has not collected ozone data, and changes in the ozone monitoring season have been observed for States with similar climatology, then those changes in the ozone monitoring season should also be implemented for the State that does not collect adequate ozone data.
States adjacent to Idaho with similar climatology include Montana, Oregon, Utah, and Washington. According to 40 CFR 58, Appendix D, section 2.5, the ozone monitoring seasons identified for these states are shown in Table 1:
The longest ozone monitoring season for these states is May through September. This shows that the monitoring season for Idaho should be changed to May through September to be consistent with those states with similar climatology.
Although Idaho itself has not gathered sufficient ozone data to support a Start Printed Page 52838change in monitoring seasons, EPA has evaluated the data which has been gathered in the state to ensure any changes in the ozone monitoring season based on the guidance will be consistent with information that has been collected.The only ozone monitoring site in Idaho where six years of ozone data exists is in the Craters of the Moon Monument, which is a Class 1 area. The purpose of the Craters of the Moon ozone site is to measure ozone trends and to track degradation of air quality in a Class 1 area. This monitor has not measured any exceedances of the ozone standard since monitoring began at this site in 1992. However, the Craters of the Moon site is not representative of ozone concentrations which occur in highly populated areas of Idaho, such as in the Treasure Valley, where the state capital of Boise is located. Ozone monitoring was initiated in the Treasure Valley in May 2000 by the Idaho Department of Environmental Quality (IDEQ). As an indication of how the Treasure Valley ozone concentrations compare to the 8-hour ozone standard (0.08 ppm), IDEQ compared the maximum 8-hour ozone concentration for each month during 2001, 2002, and 2003 to the ozone standard. The results of this comparison demonstrate that the ozone concentrations exceed 80% of the standard, but do not exceed the standard, only during the months of May through September. Based on this analysis, which conservatively compares the monitoring data to 80% of the standard, it is evident that ozone concentrations are only likely to exceed the 8-hour standard in the Treasure Valley during the months of May through September.
IV. Final Action
In this action, EPA is approving a change in the ozone monitoring season in Idaho. The reference to the ozone monitoring season for Idaho found in 40 CFR part 58, Appendix D, section 2.5, will be changed from April through October to May through September.
V. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely changes the ozone monitoring season for Idaho which appears in 40 CFR Part 58, Appendix D, section 2.5. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 29, 2004. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)Start List of Subjects
