Data for the 1997 Annual Fine
Particulate Matter Standards and 2006
24-Hour Fine Particulate Standards
Environmental Protection
Agency (EPA).
ACTION: Proposed rule.
AGENCY:
EPA is proposing to make two
determinations, one regarding the
Knoxville, Tennessee, 1997 annual fine
particulate (PM2.5) nonattainment area
and one regarding the KnoxvilleSevierville-La Follette, Tennessee, 2006
24-hour PM2.5 nonattainment area (both
areas have the same geographic
boundary and will hereafter be
collectively referred to as the ‘‘Knoxville
Area’’ or ‘‘Area’’). First, EPA is
proposing to determine that the Area
has attained the 1997 annual average
PM2.5 National Ambient Air Quality
Standards (NAAQS or ‘‘standard’’).
Second, EPA is proposing to determine
that the area has attained the 2006 24hour PM2.5 NAAQS. These proposed
determinations of attaining data are
based upon complete, quality-assured
and certified ambient air monitoring
data for the 2009–2011 period, showing
that the Area has monitored attainment
of the 1997 annual PM2.5 NAAQS and
2006 24-hour PM2.5 NAAQS. If EPA
finalizes these proposed determinations
of attaining data, the requirements for
the Area to submit attainment
demonstrations and associated
reasonably available control measures
(RACM), reasonable further progress
(RFP) plans, contingency measures, and
other planning state implementation
plan (SIP) revisions related to
attainment of the standards shall be
suspended so long as the Area continues
to attain the respective PM2.5 NAAQS.
DATES: Comments must be received on
or before July 6, 2012.

I. What actions is EPA taking?
EPA is proposing to determine that
the Knoxville Area (comprised of
Anderson, Blount, Knox, and Loudon
Counties in their entireties and a
portion of Roane County) have
monitored attaining data for the 1997
annual and 2006 24-hour PM2.5 NAAQS.
The proposal is based upon complete,
quality-assured and certified ambient air
monitoring data for the 2009–2011
monitoring period.

Federal Register / Vol. 77, No. 109 / Wednesday, June 6, 2012 / Proposed Rules
II. What is the background for these
actions?
On July 18, 1997 (62 FR 36852), EPA
established an annual PM2.5 NAAQS at
15.0 micrograms per cubic meter (mg/
m3) based on a 3-year average of annual
mean PM2.5 concentrations. At that time,
EPA also established a 24-hour NAAQS
of 65 mg/m3. See 40 CFR 50.7. On
January 5, 2005 (70 FR 944), EPA
published its air quality designations
and classifications for the 1997 PM2.5
NAAQS based upon air quality
monitoring data from those monitors for
calendar years 2001–2003. These
designations became effective on April
5, 2005. The Knoxville Area was
designated nonattainment for the 1997
annual PM2.5 NAAQS. See 40 CFR
81.343.
On October 17, 2006 (71 FR 61144),
EPA retained the 1997 annual PM2.5
NAAQS at 15.0 mg/m3 based on a 3-year
average of annual mean PM2.5
concentrations, and promulgated a
24-hour NAAQS of 35 mg/m3 based on
a 3-year average of the 98th percentile
of 24-hour concentrations. The process
for designating areas following
promulgation of a new or revised
NAAQS is contained in section
107(d)(1) of the Clean Air Act (CAA).
EPA and state air quality agencies
initiated the monitoring process for the
PM2.5 NAAQS in 1999 and began
operating all air quality monitors by
January 2001. On November 13, 2009,
EPA published its air quality
designations and classifications for the
2006 24-hour PM2.5 NAAQS based upon
air quality monitoring data from those
monitors for calendar years 2006–2008
(74 FR 58688). Those designations
became effective on December 14, 2009.
The Knoxville Area was designated
nonattainment for the 2006 24-hour
PM2.5 NAAQS (see 40 CFR part 81).1
In response to legal challenges of the
annual NAAQS promulgated in 2006,
the U.S. Court of Appeals for the District
of Columbia Circuit (D.C. Circuit)
remanded this NAAQS to EPA for
further consideration. See American
Farm Bureau Federation and National
Pork Producers Council, et al. v. EPA,
559 F.3d 512 (D.C. Cir. 2009). However,
given that the 1997 and 2006 annual
NAAQS are essentially identical,
attainment of the 1997 annual NAAQS
would also indicate attainment of the
remanded 2006 annual NAAQS.
On April 25, 2007 (72 FR 20664), EPA
promulgated its PM2.5 implementation
rule, codified at 40 CFR part 51, subpart
Z, in which the Agency provided
guidance for state and tribal plans to
implement the 1997 PM2.5 NAAQS. This
rule, at 40 CFR 51.1004(c), specifies
some of the regulatory consequences of
attaining the NAAQS, as discussed
below. While 40 CFR 51.1004(c) was
promulgated as part of a set of
regulations addressing the PM2.5
NAAQS promulgated in 1997, EPA
believes that the same approach is
warranted with respect to the PM2.5
NAAQS promulgated in 2006. See
‘‘Implementation Guidance for the 2006
24–Hour Fine Particle (PM2.5) National
Ambient Air Quality Standards
(NAAQS),’’ March 2, 2012, available
online at https://www.epa.gov/ttn/naaqs/
pm/pm25_guide.html.
III. Does the Knoxville Area meet the
1997 annual PM2.5 NAAQS?
A. Criteria
Today’s proposed rulemaking assesses
whether the Knoxville Area has attained
the 1997 annual PM2.5 NAAQS, based
on the most recent three years of
quality-assured data. Under EPA
regulations at 40 CFR 50.7, the 1997
annual primary and secondary PM2.5
standards are met when the annual
arithmetic mean concentration, as
determined in accordance with 40 CFR
part 50, Appendix N, is less than or
equal to 15.0 mg/m3 at all relevant
monitoring sites in the subject area.
B. Knoxville Area Air Quality
EPA has reviewed the ambient air
monitoring data for the Knoxville Area
in accordance with the provisions of 40
CFR part 50, Appendix N. All data
considered have been quality-assured,
certified, and recorded in EPA’s Air
Quality System (AQS) database. The
2009–2011 data are used for the
determination of attaining data because
that is the most recent period of
certified data available to EPA.
Table 1 and the related discussion
below show that the Area is attaining
the standard based on available data for
2009–2011. Less than 75 percent of the
data were collected at the Bearden
Middle School site for the second
quarter of 2009 and the fourth quarter
for 2010. EPA performed a quarterly
maximum data substitution test using
40 CFR part 50 Appendix N and the
April 1999 Guideline on Data Handling
Conventions for the PM NAAQS
(www.epa.gov/ttncaaa1/t1/memoranda/
pmfinal.pdf) for the Bearden Middle
School monitor for the quarters with
less than 75 percent complete data. Less
than 75 percent of the data were
collected at the Air Lab site for the first
quarter of 2010. Coarse particular matter
(PM10) data substitution, using the April
1999 Guideline on Data Handling
Conventions for the PM NAAQS
(www.epa.gov/ttncaaa1/t1/memoranda/
pmfinal.pdf), was applied at the Air Lab
site because a PM10 sampler is colocated at the site. PM10 data
substitution was used instead of max
value substitution because the
substituted values were higher. The
three-year annual design values both
with and without data substitution are
provided in Table 1 below. EPA’s
review of these data indicates that the
Knoxville Area has met the 1997 annual
PM2.5 NAAQS.

The Bearden Middle School monitor
has a preliminary 2009–2011 PM2.5
annual design value of 11.6 mg/m3.
Since the monitor had incomplete
quarters during the second quarter of
2009 and fourth quarter of 2010,
quarterly maximum data substitution
was conducted. The annual mean was
recalculated, and the resulting 2009–
2011 PM2.5 annual design value with
data substitution is 12.4 mg/m3. The Air
Lab monitor has a preliminary 2009–
2011 PM2.5 annual design value of 12.3
mg/m3. The monitor had one incomplete
quarter during the first quarter of 2010,
and PM10 data substitution was
conducted. The annual mean was
recalculated, and the resulting 2009–
2011 PM2.5 annual design value with
data substitution is 12.9 mg/m3. Because
the design values with data substitution
are below the 15.0 mg/m3 standard, both
monitors are considered to be attaining
the 1997 annual NAAQS. The official
design values of the monitors are 11.6
mg/m3 and 12.3 mg/m3, respectively. On
the basis of this review, EPA is
proposing to determine that the
Knoxville Area has attained the 1997
annual PM2.5 NAAQS.
C. Has the Knoxville Area met the 1997
annual PM2.5 air quality standard?
EPA has reviewed the ambient air
monitoring data for PM2.5, consistent
with the requirements contained in 40
CFR part 50 and recorded the data in the
EPA AQS database, for the Knoxville
Area. Based on EPA’s review of the data
for 2009–2011, EPA proposes to
determine that the Area attained the
1997 annual PM2.5 NAAQS.
IV. Does the Knoxville Area meet the
2006 24-hour PM2.5 NAAQS?
A. Criteria
Today’s proposed rulemaking assesses
whether the Knoxville Area has attained
the 2006 24-hour PM2.5 NAAQS, based
on the most recent three years of
quality-assured data. Under EPA
regulations at 40 CFR 50.13, the 2006
24-hour primary and secondary PM2.5
standards are met when the 98th
percentile 24-hour concentration, as
determined in accordance with 40 CFR
part 50, Appendix N, is less than or
equal to 35 mg/m3 at all relevant
monitoring sites in the subject area.
B. Knoxville Area Air Quality
EPA has reviewed the ambient air
monitoring data for the Knoxville Area
in accordance with the provisions of 40
CFR part 50, Appendix N. All data
considered have been quality-assured,
certified, and recorded in EPA’s AQS
database. The 2009–2011 data are used
for the determination of attaining data
because that is the most recent period of
certified data available to EPA.
Table 2 and the related discussion
below show that the Area is attaining
the standard based on available data for
2009–2011. Less than 75 percent of the
data were collected at the Bearden
Middle School site for the second
quarter of 2009 and the fourth quarter
for 2010. EPA performed a quarterly
maximum data substitution test using
40 CFR part 50 Appendix N and the
April 1999 Guideline on Data Handling
Conventions for the PM NAAQS
(www.epa.gov/ttncaaa1/t1/memoranda/
pmfinal.pdf) for the Bearden Middle
School monitor for the quarters with
less than 75 percent complete data. Less
than 75 percent of the data were
collected at the Air Lab site for the first
quarter of 2010. Coarse particulate
matter (PM10) data substitution, using
the April 1999 Guideline on Data
Handling Conventions for the PM
NAAQS (www.epa.gov/ttncaaa1/t1/
memoranda/pmfinal.pdf), was applied
at the Air Lab site because a PM10
sampler is co-located at the site. PM10
data substitution was used instead of
max value substitution because the
substituted values were higher. The
three-year annual design values both
with and without data substitution are
provided in Table 2 below. EPA’s
review of these data indicates that the
Knoxville Area has met the 2006 24hour PM2.5 NAAQS.

data substitution was conducted. The
24-hour mean was recalculated, and the
resulting 2009–2011 PM2.5 24-hour
design value with data substitution is 27
mg/m3. The Air Lab monitor has a
preliminary 2009–2011 PM2.5 24-hour
design value of 24 mg/m3. The monitor
had one incomplete quarter during the
first quarter of 2010, and PM10 data
substitution was conducted. The 24hour mean was recalculated, and the
resulting 2009–2011 PM2.5 24-hour
design value with data substitution is 29
mg/m3. Because the design values with
data substitution are below the 35 mg/m3
standard, both monitors are considered
to be attaining the 2006 24-hour
NAAQS. The official design values of
the monitors are 24 mg/m3 and 24 mg/m3,
respectively. On the basis of this review,
EPA is proposing to determine that the
Knoxville Area has attained the 2006
24-hour PM2.5 NAAQS.
mstockstill on DSK4VPTVN1PROD with PROPOSALS
C. Has the Knoxville Area met the 2006
24-hour PM2.5 air quality standard?
EPA has reviewed the ambient air
monitoring data for PM2.5, consistent
with the requirements contained in 40
CFR part 50 and recorded the data in the
EPA AQS database, for the Knoxville
Area. Based on EPA’s review of the data
for 2009–2011, EPA proposes to
determine that the Area attained the
2006 24-hour PM2.5 NAAQS.
V. What is the effect of these actions?
If these proposed determinations of
attaining data are made final, the
requirements for the Knoxville Area to
submit attainment demonstrations and
associated RACM, RFP plans,
contingency measures, and any other
planning SIPs related to attainment of
either the 1997 annual or the 2006 24hour PM2.5 NAAQS would be
suspended for so long as the Area
continues to attain the applicable PM2.5
NAAQS. See 40 CFR 51.1004(c).
Notably, as described below, any such
determination would not be equivalent
to the redesignation of the Area to
attainment for the 1997 annual or 2006
24-hour PM2.5 NAAQS.
If these proposed rulemakings are
finalized and EPA subsequently
determines, after notice-and-comment
rulemaking in the Federal Register, that
the Area has violated either the 1997
annual or 2006 24-hour PM2.5 NAAQS,
the basis for the suspension of the
specific requirements would no longer
exist for the Knoxville Area for the
NAAQS (i.e, the 1997 annual or the
2006 24-hour NAAQS) which was
violated, and the Area would thereafter
have to address the applicable
requirements for that particular
NAAQS. See 40 CFR 51.1004(c).
VerDate Mar<15>2010
16:11 Jun 05, 2012
Jkt 226001
Finalizing these proposed actions
would not constitute a redesignation of
the Area to attainment of the 1997
annual or 2006 24-hour PM2.5 NAAQS
under section 107(d)(3) of the CAA.
Further, finalizing these proposed
actions does not involve approving a
maintenance plan for the Area as
required under section 175A of the
CAA, nor would it find that the Area
has met all other requirements for
redesignation. Even if EPA finalizes the
proposed actions, the designation status
of the Knoxville Area would remain
nonattainment for the 1997 annual and
2006 24-hour PM2.5 NAAQS until such
time as EPA determines that the Area
meets the CAA requirements for
redesignation to attainment and takes
action to redesignate the Area.
If the Knoxville Area continues to
monitor attainment of the 1997 annual
PM2.5 NAAQS, the requirements for the
Knoxville Area to submit an attainment
demonstration and associated RACM,
RFP plan, contingency measures, and
any other planning SIPs related to
attainment of the 1997 annual PM2.5
NAAQS will remain suspended.
Further, if the Knoxville Area continues
to monitor attainment of the 2006 24hour PM2.5 NAAQS, the requirements
for the Knoxville Area to submit an
attainment demonstration and
associated RACM, RFP plan,
contingency measures, and any other
planning SIPs related to attainment of
the 2006 24-hour PM2.5 NAAQS will
remain suspended.
VI. Statutory and Executive Order
Reviews
These actions propose to make
determinations of attaining data 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, these proposed actions:
• Are not ‘‘significant regulatory
actions’’ subject to review by the Office
of Management and Budget under
Executive Order 12866 (58 FR 51735,
October 4, 1993);
• Do not impose an information
collection burden under the provisions
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• Are certified as not having a

Approval and Promulgation of Implementation Plans and
Designations of Areas for Air Quality Planning Purposes; Tennessee:
Knoxville; Determination of Attaining Data for the 1997 Annual Fine
Particulate Matter Standards and 2006 24-Hour Fine Particulate
Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to make two determinations, one regarding the
Knoxville, Tennessee, 1997 annual fine particulate (PM2.5)
nonattainment area and one regarding the Knoxville-Sevierville-La
Follette, Tennessee, 2006 24-hour PM2.5 nonattainment area
(both areas have the same geographic boundary and will hereafter be
collectively referred to as the ``Knoxville Area'' or ``Area''). First,
EPA is proposing to determine that the Area has attained the 1997
annual average PM2.5 National Ambient Air Quality Standards
(NAAQS or ``standard''). Second, EPA is proposing to determine that the
area has attained the 2006 24-hour PM2.5 NAAQS. These
proposed determinations of attaining data are based upon complete,
quality-assured and certified ambient air monitoring data for the 2009-
2011 period, showing that the Area has monitored attainment of the 1997
annual PM2.5 NAAQS and 2006 24-hour PM2.5 NAAQS.
If EPA finalizes these proposed determinations of attaining data, the
requirements for the Area to submit attainment demonstrations and
associated reasonably available control measures (RACM), reasonable
further progress (RFP) plans, contingency measures, and other planning
state implementation plan (SIP) revisions related to attainment of the
standards shall be suspended so long as the Area continues to attain
the respective PM2.5 NAAQS.

VI. Statutory and Executive Order Reviews
I. What actions is EPA taking?
EPA is proposing to determine that the Knoxville Area (comprised of
Anderson, Blount, Knox, and Loudon Counties in their entireties and a
portion of Roane County) have monitored attaining data for the 1997
annual and 2006 24-hour PM2.5 NAAQS. The proposal is based
upon complete, quality-assured and certified ambient air monitoring
data for the 2009-2011 monitoring period.
[[Page 33361]]
II. What is the background for these actions?
On July 18, 1997 (62 FR 36852), EPA established an annual
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\)
based on a 3-year average of annual mean PM2.5
concentrations. At that time, EPA also established a 24-hour NAAQS of
65 [mu]g/m\3\. See 40 CFR 50.7. On January 5, 2005 (70 FR 944), EPA
published its air quality designations and classifications for the 1997
PM2.5 NAAQS based upon air quality monitoring data from
those monitors for calendar years 2001-2003. These designations became
effective on April 5, 2005. The Knoxville Area was designated
nonattainment for the 1997 annual PM2.5 NAAQS. See 40 CFR
81.343.
On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual
PM2.5 NAAQS at 15.0 [mu]g/m\3\ based on a 3-year average of
annual mean PM2.5 concentrations, and promulgated a 24-hour
NAAQS of 35 [mu]g/m\3\ based on a 3-year average of the 98th percentile
of 24-hour concentrations. The process for designating areas following
promulgation of a new or revised NAAQS is contained in section
107(d)(1) of the Clean Air Act (CAA). EPA and state air quality
agencies initiated the monitoring process for the PM2.5
NAAQS in 1999 and began operating all air quality monitors by January
2001. On November 13, 2009, EPA published its air quality designations
and classifications for the 2006 24-hour PM2.5 NAAQS based
upon air quality monitoring data from those monitors for calendar years
2006-2008 (74 FR 58688). Those designations became effective on
December 14, 2009. The Knoxville Area was designated nonattainment for
the 2006 24-hour PM2.5 NAAQS (see 40 CFR part 81).\1\
---------------------------------------------------------------------------
\1\ On February 3, 2011, EPA made a technical correction to the
name of the Knoxville, Tennessee, nonattainment area included in the
November 13, 2009 (74 FR 58688), Federal Register action designating
nonattainment areas for the 2006 24-hour PM2.5 NAAQS. The
name of the Knoxville, Tennessee, nonattainment area for this NAAQS
was changed at 40 CFR 81.343 to be the Knoxville-Sevierville-La
Follette, Tennessee, nonattainment area to correspond with the name
of the Core Based Statistical Area and to provide an accurate area
name in the CFR. See 76 FR 6056, February 3, 2011. The geographic
boundaries of the Knoxville-Sevierville-La Follette nonattainment
area for the 24-hour PM2.5 NAAQS are the same as for the
Knoxville nonattainment area for the annual PM2.5 NAAQS.
---------------------------------------------------------------------------
In response to legal challenges of the annual NAAQS promulgated in
2006, the U.S. Court of Appeals for the District of Columbia Circuit
(D.C. Circuit) remanded this NAAQS to EPA for further consideration.
See American Farm Bureau Federation and National Pork Producers
Council, et al. v. EPA, 559 F.3d 512 (D.C. Cir. 2009). However, given
that the 1997 and 2006 annual NAAQS are essentially identical,
attainment of the 1997 annual NAAQS would also indicate attainment of
the remanded 2006 annual NAAQS.
On April 25, 2007 (72 FR 20664), EPA promulgated its
PM2.5 implementation rule, codified at 40 CFR part 51,
subpart Z, in which the Agency provided guidance for state and tribal
plans to implement the 1997 PM2.5 NAAQS. This rule, at 40
CFR 51.1004(c), specifies some of the regulatory consequences of
attaining the NAAQS, as discussed below. While 40 CFR 51.1004(c) was
promulgated as part of a set of regulations addressing the
PM2.5 NAAQS promulgated in 1997, EPA believes that the same
approach is warranted with respect to the PM2.5 NAAQS
promulgated in 2006. See ``Implementation Guidance for the 2006 24-Hour
Fine Particle (PM2.5) National Ambient Air Quality Standards
(NAAQS),'' March 2, 2012, available online at https://www.epa.gov/ttn/naaqs/pm/pm25_guide.html.
III. Does the Knoxville Area meet the 1997 annual PM2.5
NAAQS?
A. Criteria
Today's proposed rulemaking assesses whether the Knoxville Area has
attained the 1997 annual PM2.5 NAAQS, based on the most
recent three years of quality-assured data. Under EPA regulations at 40
CFR 50.7, the 1997 annual primary and secondary PM2.5
standards are met when the annual arithmetic mean concentration, as
determined in accordance with 40 CFR part 50, Appendix N, is less than
or equal to 15.0 [micro]g/m\3\ at all relevant monitoring sites in the
subject area.
B. Knoxville Area Air Quality
EPA has reviewed the ambient air monitoring data for the Knoxville
Area in accordance with the provisions of 40 CFR part 50, Appendix N.
All data considered have been quality-assured, certified, and recorded
in EPA's Air Quality System (AQS) database. The 2009-2011 data are used
for the determination of attaining data because that is the most recent
period of certified data available to EPA.
Table 1 and the related discussion below show that the Area is
attaining the standard based on available data for 2009-2011. Less than
75 percent of the data were collected at the Bearden Middle School site
for the second quarter of 2009 and the fourth quarter for 2010. EPA
performed a quarterly maximum data substitution test using 40 CFR part
50 Appendix N and the April 1999 Guideline on Data Handling Conventions
for the PM NAAQS (www.epa.gov/ttncaaa1/t1/memoranda/pmfinal.pdf) for
the Bearden Middle School monitor for the quarters with less than 75
percent complete data. Less than 75 percent of the data were collected
at the Air Lab site for the first quarter of 2010. Coarse particular
matter (PM10) data substitution, using the April 1999
Guideline on Data Handling Conventions for the PM NAAQS (www.epa.gov/ttncaaa1/t1/memoranda/pmfinal.pdf), was applied at the Air Lab site
because a PM10 sampler is co-located at the site.
PM10 data substitution was used instead of max value
substitution because the substituted values were higher. The three-year
annual design values both with and without data substitution are
provided in Table 1 below. EPA's review of these data indicates that
the Knoxville Area has met the 1997 annual PM2.5 NAAQS.

The Bearden Middle School monitor has a preliminary 2009-2011
PM2.5 annual design value of 11.6 [mu]g/m\3\. Since the
monitor had incomplete quarters during the second quarter of 2009 and
fourth quarter of 2010, quarterly maximum data substitution was
conducted. The annual mean was recalculated, and the resulting 2009-
2011 PM2.5 annual design value with data substitution is
12.4 [mu]g/m\3\. The Air Lab monitor has a preliminary 2009-2011
PM2.5 annual design value of 12.3 [mu]g/m\3\. The monitor
had one incomplete quarter during the first quarter of 2010, and
PM10 data substitution was conducted. The annual mean was
recalculated, and the resulting 2009-2011 PM2.5 annual
design value with data substitution is 12.9 [mu]g/m\3\. Because the
design values with data substitution are below the 15.0 [mu]g/m\3\
standard, both monitors are considered to be attaining the 1997 annual
NAAQS. The official design values of the monitors are 11.6 [mu]g/m\3\
and 12.3 [mu]g/m\3\, respectively. On the basis of this review, EPA is
proposing to determine that the Knoxville Area has attained the 1997
annual PM2.5 NAAQS.
C. Has the Knoxville Area met the 1997 annual PM2.5 air quality
standard?
EPA has reviewed the ambient air monitoring data for
PM2.5, consistent with the requirements contained in 40 CFR
part 50 and recorded the data in the EPA AQS database, for the
Knoxville Area. Based on EPA's review of the data for 2009-2011, EPA
proposes to determine that the Area attained the 1997 annual
PM2.5 NAAQS.
IV. Does the Knoxville Area meet the 2006 24-hour PM2.5
NAAQS?
A. Criteria
Today's proposed rulemaking assesses whether the Knoxville Area has
attained the 2006 24-hour PM2.5 NAAQS, based on the most
recent three years of quality-assured data. Under EPA regulations at 40
CFR 50.13, the 2006 24-hour primary and secondary PM2.5
standards are met when the 98th percentile 24-hour concentration, as
determined in accordance with 40 CFR part 50, Appendix N, is less than
or equal to 35 [micro]g/m\3\ at all relevant monitoring sites in the
subject area.
B. Knoxville Area Air Quality
EPA has reviewed the ambient air monitoring data for the Knoxville
Area in accordance with the provisions of 40 CFR part 50, Appendix N.
All data considered have been quality-assured, certified, and recorded
in EPA's AQS database. The 2009-2011 data are used for the
determination of attaining data because that is the most recent period
of certified data available to EPA.
Table 2 and the related discussion below show that the Area is
attaining the standard based on available data for 2009-2011. Less than
75 percent of the data were collected at the Bearden Middle School site
for the second quarter of 2009 and the fourth quarter for 2010. EPA
performed a quarterly maximum data substitution test using 40 CFR part
50 Appendix N and the April 1999 Guideline on Data Handling Conventions
for the PM NAAQS (www.epa.gov/ttncaaa1/t1/memoranda/pmfinal.pdf) for
the Bearden Middle School monitor for the quarters with less than 75
percent complete data. Less than 75 percent of the data were collected
at the Air Lab site for the first quarter of 2010. Coarse particulate
matter (PM10) data substitution, using the April 1999
Guideline on Data Handling Conventions for the PM NAAQS (www.epa.gov/ttncaaa1/t1/memoranda/pmfinal.pdf), was applied at the Air Lab site
because a PM10 sampler is co-located at the site.
PM10 data substitution was used instead of max value
substitution because the substituted values were higher. The three-year
annual design values both with and without data substitution are
provided in Table 2 below. EPA's review of these data indicates that
the Knoxville Area has met the 2006 24-hour PM2.5 NAAQS.

The Bearden Middle School monitor has a preliminary 2009-2011
PM2.5 24-hour design value of 24 [mu]g/m\3\. Since the
monitor had incomplete quarters during the second quarter of 2009 and
fourth quarter of 2010, quarterly maximum
[[Page 33363]]
data substitution was conducted. The 24-hour mean was recalculated, and
the resulting 2009-2011 PM2.5 24-hour design value with data
substitution is 27 [mu]g/m\3\. The Air Lab monitor has a preliminary
2009-2011 PM2.5 24-hour design value of 24 [mu]g/m\3\. The
monitor had one incomplete quarter during the first quarter of 2010,
and PM10 data substitution was conducted. The 24-hour mean
was recalculated, and the resulting 2009-2011 PM2.5 24-hour
design value with data substitution is 29 [mu]g/m\3\. Because the
design values with data substitution are below the 35 [mu]g/m\3\
standard, both monitors are considered to be attaining the 2006 24-hour
NAAQS. The official design values of the monitors are 24 [mu]g/m\3\ and
24 [mu]g/m\3\, respectively. On the basis of this review, EPA is
proposing to determine that the Knoxville Area has attained the 2006
24-hour PM2.5 NAAQS.
C. Has the Knoxville Area met the 2006 24-hour PM2.5 air quality
standard?
EPA has reviewed the ambient air monitoring data for
PM2.5, consistent with the requirements contained in 40 CFR
part 50 and recorded the data in the EPA AQS database, for the
Knoxville Area. Based on EPA's review of the data for 2009-2011, EPA
proposes to determine that the Area attained the 2006 24-hour
PM2.5 NAAQS.
V. What is the effect of these actions?
If these proposed determinations of attaining data are made final,
the requirements for the Knoxville Area to submit attainment
demonstrations and associated RACM, RFP plans, contingency measures,
and any other planning SIPs related to attainment of either the 1997
annual or the 2006 24-hour PM2.5 NAAQS would be suspended
for so long as the Area continues to attain the applicable
PM2.5 NAAQS. See 40 CFR 51.1004(c). Notably, as described
below, any such determination would not be equivalent to the
redesignation of the Area to attainment for the 1997 annual or 2006 24-
hour PM2.5 NAAQS.
If these proposed rulemakings are finalized and EPA subsequently
determines, after notice-and-comment rulemaking in the Federal
Register, that the Area has violated either the 1997 annual or 2006 24-
hour PM2.5 NAAQS, the basis for the suspension of the
specific requirements would no longer exist for the Knoxville Area for
the NAAQS (i.e, the 1997 annual or the 2006 24-hour NAAQS) which was
violated, and the Area would thereafter have to address the applicable
requirements for that particular NAAQS. See 40 CFR 51.1004(c).
Finalizing these proposed actions would not constitute a
redesignation of the Area to attainment of the 1997 annual or 2006 24-
hour PM2.5 NAAQS under section 107(d)(3) of the CAA.
Further, finalizing these proposed actions does not involve approving a
maintenance plan for the Area as required under section 175A of the
CAA, nor would it find that the Area has met all other requirements for
redesignation. Even if EPA finalizes the proposed actions, the
designation status of the Knoxville Area would remain nonattainment for
the 1997 annual and 2006 24-hour PM2.5 NAAQS until such time
as EPA determines that the Area meets the CAA requirements for
redesignation to attainment and takes action to redesignate the Area.
If the Knoxville Area continues to monitor attainment of the 1997
annual PM2.5 NAAQS, the requirements for the Knoxville Area
to submit an attainment demonstration and associated RACM, RFP plan,
contingency measures, and any other planning SIPs related to attainment
of the 1997 annual PM2.5 NAAQS will remain suspended.
Further, if the Knoxville Area continues to monitor attainment of the
2006 24-hour PM2.5 NAAQS, the requirements for the Knoxville
Area to submit an attainment demonstration and associated RACM, RFP
plan, contingency measures, and any other planning SIPs related to
attainment of the 2006 24-hour PM2.5 NAAQS will remain
suspended.
VI. Statutory and Executive Order Reviews
These actions propose to make determinations of attaining data
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, these
proposed actions:
Are not ``significant regulatory actions'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
Do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Are 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.);
Do 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);
Do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Are not economically significant regulatory actions based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Are not significant regulatory actions subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Are 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
Do 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,
these proposed 1997 annual and 2006 24-hour PM2.5 NAAQS
determinations for the Knoxville Area do 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.
For purposes of judicial review, the two determinations proposed by
today's action are severable from one another.
