The EPA issued “The Treatment of Data Influenced by Exceptional Events (Exceptional Event Rule): Revised Exceptional Event Data Flagging Submittal and Documentation Schedule for Monitoring Data Used in Designations for the 2008 Ozone NAAQS” as a direct final rule on October 6, 2008, 73 FR 58042. The direct final rule revises the schedule for the flagging and submission of documentation of data impacted by exceptional events that may be used for designations under the 2008 ozone national ambient air quality standards (NAAQS). For a detailed description of the ozone NAAQS and the Exceptional Events Rule, please see the rulemaking actions which are available at EPA's Web Sites at http://www.epa.gov/groundlevelozone/actions.html and http://www.epa.gov/EPA-AIR/2008/October/Day-06/a23520.htm and also in the Federal Register at 73 FR 16436 and 73 FR 58042
Need for Correction
As published, the final preamble and regulation contains minor errors which may prove to be misleading and are in need of clarification. EPA finds that there is good cause to make these corrections without providing for notice and comments because neither notice nor comment is necessary and would not be in the public interest due to the nature of the corrections which are minor, technical and do not change the obligations already existing in the rule. EPA finds that the corrections are merely correcting identifying information that references the previously promulgated Ozone NAAQS.
Corrections of Publication
In the preamble to the direct final rule for “The Treatment of Data Influenced by Exceptional Events (Exceptional Event Rule): Revised Exceptional Event Data Flagging Submittal and Documentation Schedule To Support Initial Area Designations for the 2008 Ozone NAAQS,” October 6, 2008, 73 FR 58042, EPA is correcting the preamble text at 73 FR 58044, column 2, which refers to the ozone NAAQS in terms of “pounds per billion (ppb)” to “parts per million (ppm)” to accurately reflect the ozone NAAQS.
Similarly, correction is also being made at 73 FR 58045 in “TABLE 1—SCHEDULE FOR EXCEPTIONAL EVENT FLAGGING AND DOCUMENTATION SUBMISSION FOR DATA TO BE USED IN DESIGNATIONS DECISIONS FOR NEW OR REVISED NAAQS” to change the term “(ppb)” to “(ppm)” to accurately reflect the ozone NAAQS.
In the regulatory text, EPA is also correcting the inadvertent minor error in § 50.14 by revising paragraph (c)(2)(v) to correct the text in “Table 1” by changing the term “(ppb)” to “(ppm).”Start Signature

(v) When EPA sets a NAAQS for a new pollutant or revises the NAAQS for an existing pollutant, it may revise or set a new schedule for flagging exceptional event data, providing initial data descriptions and providing detailed data documentation in AQS for the initial designations of areas for those NAAQS: Table 1 provides the schedule for submission of flags with initial descriptions in AQS and detailed documentation and the schedule shall apply for those data which will or may influence the initial designation of areas for those NAAQS. EPA anticipates revising Table 1 as necessary to accommodate revised data submission schedules for new or revised NAAQS. Start Printed Page 70598
