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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Correcting Amendments.

-----------------------------------------------------------------------

SUMMARY: The EPA issued a direct final rule on October 6, 2008, 
entitled, ``The Treatment of Data Influenced by Exceptional Events 
(Exceptional Events Rule): Revised Exceptional Event Data Flagging 
Submittal and Documentation Schedule for Monitoring Data Used in 
Designations for the 2008 Ozone NAAQS.'' This document makes a minor 
correction to the Exceptional Events Rule to correct typographical 
errors in the technical notation of the ozone standard contained in the 
preamble and regulatory text for the rule.

DATES: Effective Date: This document is effective on December 22, 2008.

corrections, contact Thomas E. Link, Air Quality Planning Division,

SUPPLEMENTARY INFORMATION: 

Background

    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 Sec.  50.14 by revising paragraph (c)(2)(v) to correct 
the text in ``Table 1'' by changing the term ``(ppb)'' to ``(ppm).''

    Dated: November 17, 2008.

Administrator.

For the reasons set forth in the preamble, part 50 of chapter I of 
title 40 of the Code of Federal Regulations is amended as follows:

PART 50--[AMENDED]

1. The authority citation for part 50 continues to read as follows:

    Authority: 42 U.S.C. 7401 et seq.

0
2. Section 50.14 is amended by revising paragraph (c)(2)(v) to read as 
follows:

Subpart A--General Provisions

Sec.  50.14  Treatment of air quality monitoring data influenced by 
exceptional events.

* * * * *
    (c) * * *
    (2) * * *
    (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.
