Approval and Promulgation of Implementation Plans and
Designations of Areas for Air Quality Planning Purposes; Georgia:
Atlanta; Determination of Attainment for the 1997 8-Hour Ozone
Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to determine that the Atlanta, Georgia
nonattainment area has attained the 1997 8-hour ozone national ambient
air quality standards (NAAQS) based on quality assured, quality
controlled monitoring data from 2008-2010. The Atlanta, Georgia 1997 8-
hour ozone nonattainment area (hereafter referred to as the ``Atlanta
Area'') is comprised of Barrow, Bartow, Carroll, Cherokee, Clayton,
Cobb, Coweta, Dekalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett,
Hall, Henry, Newton, Paulding, Rockdale, Spalding and Walton Counties
in Georgia. If this proposed determination is made final, the
requirement for the State of Georgia to submit an attainment
demonstration and associated reasonably available control measures
(RACM) analysis, a reasonable further progress (RFP) plan, contingency
measures, and other planning State Implementation Plans (SIPs) related
to attainment of the 1997 8-hour ozone NAAQS for the Atlanta, Georgia
8-hour ozone nonattainment area, shall be suspended for as long as the
Atlanta Area continues to meet the 1997 8-hour ozone NAAQS.

I. What action is EPA taking?
II. What is the effect of this action?
III. What is the background for this action?
IV. What is EPA's analysis of the relevant air quality data?
V. Proposed Action
VI. Statutory and Executive Order Reviews
I. What action is EPA taking?
EPA is proposing to determine that the Atlanta Area has attained
the 1997 8-hour ozone NAAQS. Today's proposal is based upon complete,
quality assured, quality controlled, and certified ambient air
monitoring data for the years 2008-2010 showing that the Atlanta Area
has monitored attainment of the 1997 8-hour ozone NAAQS. EPA is in the
process of establishing a new 8-hour ozone NAAQS, and expects to
finalize the reconsidered NAAQS by July 2011. Today's action, however,
relates only to the 1997 8-hour ozone NAAQS. Requirements for the
Atlanta Area under the 2011 NAAQS will be addressed in the future.
II. What is the effect of this action?
If this determination is made final, under the provisions of EPA's
ozone implementation rule (see 40 CFR 51.918), it would suspend the
requirement to submit an attainment demonstration and associated RACM
analysis, RFP plan, contingency measures,\1\ and any other planning
SIPs related to attainment of the 1997 8-hour ozone NAAQS. The
attainment determination would continue until such time, if any, that
EPA subsequently determines that the Atlanta Area has violated the 1997
8-hour ozone NAAQS. This determination is separate from any future
designation determination or requirements for the Atlanta Area based on
the revised or reconsidered ozone NAAQS, and would remain in effect
regardless of whether EPA designates the Atlanta Area as a
nonattainment area for purposes of a future revised or reconsidered 8-
hour ozone NAAQS.\2\ Furthermore, as described below, a final clean
data determination is not equivalent to the redesignation of the
Atlanta Area to attainment for the 1997 8-hour ozone NAAQS. If this
rulemaking is finalized and EPA subsequently determines, after notice-
and-comment rulemaking in the Federal Register, that the Atlanta Area
has violated the 1997 8-hour ozone NAAQS, the basis for the suspension
of the specific requirements, set forth at 40 CFR 51.918, would no
longer exist, and the Atlanta Area would thereafter have to address
pertinent requirements.
---------------------------------------------------------------------------
\1\ Contingency measures associated with a maintenance plan
(such as if the State opts to redesignate this Area to attainment
for the 1997 8-hour ozone NAAQS) would still be required.
\2\ As noted above, at this time the proposed determination of
attainment, if finalized, would suspend only those requirements
related to attainment that are currently applicable to the Atlanta
Area.
---------------------------------------------------------------------------
As mentioned above, the determination that EPA proposes with this
Federal Register notice is not equivalent to a redesignation of the
Atlanta Area to attainment. Finalizing this proposed action would not
constitute a redesignation of the Area to attainment of the 1997 8-hour
ozone NAAQS under section 107(d)(3) of the CAA. Further, finalizing
this proposed action does not involve approving a maintenance plan for
this Area as required under section 175A of the CAA, or affirm that the
Area has met all other requirements for redesignation. The designation
status of the Atlanta Area would remain nonattainment for the 1997 8-
hour ozone NAAQS until such time as EPA determines that it meets the
CAA requirements for redesignation to attainment. The State of
[[Page 16720]]
Georgia is currently working on a redesignation request and maintenance
plan to change the Atlanta Area's status from nonattainment to
attainment for the 1997 8-hour ozone NAAQS. EPA will consider Georgia's
redesignation request and maintenance plan for the Atlanta Area in a
rulemaking separate from today's proposed action.
This proposed action, if finalized, is limited to a determination
that the Atlanta Area has attained the 1997 8-hour ozone NAAQS. The
1997 8-hour ozone NAAQS became effective on July 18, 1997 (62 FR
38894), and are set forth at 40 CFR 50.10. On March 12, 2008, EPA
promulgated revised 8-hour ozone NAAQS. Subsequently, on January 19,
2010, EPA published a proposed rule to reconsider the 2008 8-hour ozone
NAAQS (75 FR 2938) and to propose a revised ozone NAAQS. EPA has not
yet made any designation determinations for the Atlanta Area based on
the revised 2008 8-hour ozone NAAQS. Today's proposed determination for
the Atlanta Area, and any final determination, will have no effect on,
and is not related to, any future designation determination that EPA
may make based on the revised or reconsidered ozone NAAQS for the
Atlanta Area.
If this proposed determination is made final and the Atlanta Area
continues to demonstrate attainment with the 1997 8-hour ozone NAAQS,
the obligation for the State of Georgia to submit for the Atlanta Area
an attainment demonstration and associated RACM analysis, RFP plan,
contingency measures, and any other planning SIPs related to attainment
of the 1997 8-hour ozone NAAQS will remain suspended regardless of
whether EPA designates the Atlanta Area as a nonattainment area for
purposes of the revised or reconsidered ozone NAAQS. Once the Atlanta
Area is designated for the revised or reconsidered ozone NAAQS, it will
have to meet all applicable requirements for that designation.
III. What is the background for this action?
On July 18, 1997 (62 FR 38894), EPA promulgated a revised 8-hour
ozone NAAQS of 0.08 parts per million (ppm) for both the primary and
secondary standards. These NAAQS are more stringent than the previous
1-hour ozone NAAQS. Under EPA regulations at 40 CFR part 50, the 8-hour
ozone NAAQS is attained when the 3-year average of the annual fourth-
highest daily maximum 8-hour average ambient air quality ozone
concentration is less than or equal to 0.08 ppm (i.e., 0.084 ppm when
rounding is considered). Ambient air quality monitoring data for the 3-
year period must meet a data completeness requirement. The ambient air
quality monitoring data completeness requirement is met when the
average percent of days with valid ambient monitoring data is greater
than 90 percent, and no single year has less than 75 percent data
completeness as determined in Appendix I of part 50. Specifically,
section 2.3 of 40 CFR part 50, Appendix I, ``Comparisons with the
Primary and Secondary Ozone Standards'' states:
The primary and secondary ozone ambient air quality standards
are met at an ambient air quality monitoring site when the 3-year
average of the annual fourth-highest daily maximum 8-hour average
ozone concentration is less than or equal to 0.08 ppm. The number of
significant figures in the level of the standard dictates the
rounding convention for comparing the computed 3-year average annual
fourth-highest daily maximum 8-hour average ozone concentration with
the level of the standard. The third decimal place of the computed
value is rounded, with values equal to or greater than 5 rounding
up. Thus, a computed 3-year average ozone concentration of 0.085 ppm
is the smallest value that is greater than 0.08 ppm.
On April 30, 2004 (69 FR 23857), EPA published its air quality
designations and classifications for the 1997 8-hour ozone NAAQS based
upon air quality monitoring data from those monitors for calendar years
2001-2003. These designations became effective on June 15, 2004. The
Atlanta Area is comprised of Barrow, Bartow, Carroll, Cherokee,
Clayton, Cobb, Coweta, Dekalb, Douglas, Fayette, Forsyth, Fulton,
Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton
Counties; and was designated nonattainment for the 1997 8-hour ozone
NAAQS (see 40 CFR part 81).
IV. What is EPA's analysis of the relevant air quality data?
EPA has reviewed the three most recent years of complete,
certified, quality assured and quality controlled ambient air
monitoring data for the 1997 8-hour ozone NAAQS, consistent with the
requirements contained in 40 CFR part 50, as recorded in the EPA Air
Quality System (AQS) database for the Atlanta Area. Based on that
review, EPA has preliminarily concluded that the Atlanta Area attained
the 1997 8-hour ozone NAAQS during the 2008-2010 monitoring period.
Under EPA regulations at 40 CFR 50.10, the 1997 8-hour primary and
secondary ozone ambient air quality NAAQS are met at an ambient air
quality monitoring site when the three-year average of the annual
fourth-highest daily maximum 8-hour average concentration is less than
or equal to 0.08 ppm, as determined in accordance with Appendix I of 40
CFR part 50.
Table 1 shows the design values (the metrics calculated in
accordance with 40 CFR part 50, Appendix I, for determining compliance
with the NAAQS) for the 1997 8-hour ozone NAAQS for the Atlanta Area
monitors for the years 2008-2010. Table 2 shows the data completeness
percentages for the 1997 8-hours ozone NAAQS for the Atlanta Area
monitors for the years 2008-2010.

EPA's review of these data indicate that the Atlanta Area has met
and continues to meet the 1997 8-hour ozone NAAQS. EPA is soliciting
public comments on the issues discussed in this document. These
comments will be considered before taking final action.
V. Proposed Action
EPA is proposing to determine that the Atlanta, Georgia 1997 8-hour
nonattainment area has attained the 1997 8-hour ozone NAAQS based on
2008-2010 complete, quality-assured, quality-controlled and certified
monitoring data. As provided in 40 CFR 51.918, if EPA finalizes this
determination, it would suspend the requirements for the State of
Georgia to submit, for the Atlanta Area, an attainment demonstration
and associated RACM analysis, RFP plan, contingency measures, and any
other planning SIPs related to attainment of the 1997 8-hour ozone
NAAQS as long as the Area continues to attain the 1997 8-hour ozone
NAAQS.
VI. Statutory and Executive Order Reviews
This action proposes to make a determination of attainment based on
air quality, and would, if finalized, result in the suspension of
certain federal requirements, and it would not impose additional
requirements beyond those imposed by state law. For that reason, this
proposed action:
Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994). In addition,
this proposed 1997 8-hour ozone NAAQS data determination for
[[Page 16722]]
the Atlanta Area does not have tribal implications as specified by
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP
is not approved to apply in Indian country located in the state, and
EPA notes that it will not impose substantial direct costs on tribal
governments or preempt tribal law.
