40 CFR Part 52

[EPA-R10-OAR-2012-0380; FRL-9693-9]


Approval and Promulgation of Air Quality Implementation Plans; 
Washington; Determination of Clean Data for the 2006 24-Hour Fine 
Particulate Standard for the Tacoma, Pierce County Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to determine that the Tacoma, Pierce County 
nonattainment area (hereafter referred to as ``Tacoma, Pierce County'' 
or ``the area'') for the 2006 24-hour fine particulate matter 
(PM2.5) National Ambient Air Quality Standard (NAAQS) has 
clean data for the 2006 24-hour PM2.5 NAAQS. This proposed 
determination is based upon quality-assured, quality-controlled, and 
certified ambient air monitoring data showing that the area has 
monitored attainment of the 2006 PM2.5 NAAQS based on the 
2009-2011 data available in EPA's Air Quality System (AQS) database. If 
this proposed determination is made final, the requirements for the 
area to submit an attainment demonstration, associated reasonably 
available control measures (RACM), a reasonable further progress plan 
(RFP), contingency measures, and other planning State Implementation 
Plans (SIPs) related to attainment of the standard shall be suspended 
for so long as the area continues to meet the 2006 24-hour 
PM2.5 NAAQS. This action is being taken under the Clean Air 
Act (CAA).

DATES: Written comments must be received on or before August 6, 2012.

VI. Statutory and Executive Order Reviews

I. What action is EPA taking?

    EPA is proposing to determine that the area has clean data for the 
2006 24-hour PM2.5 NAAQS. This determination is based upon 
quality-assured, quality-controlled, and certified ambient air 
monitoring data showing that the area has monitored attainment of the 
2006 PM2.5 NAAQS based on 2009-2011 monitoring data.

II. What is the effect of this action?

    If this determination is made final, under the provisions of EPA's 
PM2.5 implementation rule (40 CFR 51.1004(c)), the 
requirements for the area to submit an attainment demonstration, 
associated RACM, RFP plan, contingency measures, and any other planning 
SIP requirements related to attainment of the 2006 24-hour 
PM2.5 NAAQS would be suspended for so long as the area 
continues to meet this NAAQS. Furthermore, as described below, a final 
clean data determination would not be equivalent to a redesignation of 
the area to attainment for the 2006 24-hour PM2.5 NAAQS.
    If EPA subsequently determines that the area is in violation of the 
2006 24-hour PM2.5 NAAQS, the basis for the suspension of 
the specific requirements, set forth at 40 CFR 51.1004(c), would no 
longer exist and the area would thereafter have to address the 
pertinent requirements.
    The proposed clean data determination that the air quality data 
shows attainment of the 2006 24-hour PM2.5 NAAQS is not 
equivalent to the redesignation of the area to attainment. This 
proposed action, if finalized, will not constitute a redesignation to 
attainment under section 107(d)(3) of the CAA, because we would not yet 
have an approved maintenance plan for the area as required under 
section 175A of the CAA, nor a determination that the area has met the 
other requirements for redesignation. The designation status of the 
area would remain nonattainment for the 2006 PM2.5 NAAQS 
until such time as EPA determines that the area meets the CAA 
requirements for redesignation to attainment.

[[Page 39658]]

III. What is the background for this action?

    The 2006 PM2.5 NAAQS set forth at 40 CFR 50.13 became 
effective on December 18, 2006 (71 FR 61144) and promulgated a 24-hour 
standard of 35 micrograms per cubic meter ([micro]g/m\3\) based on a 3-
year average of the 98th percentile of 24-hour concentration. On 
December 14, 2009 (74 FR 58688), EPA made designation determinations, 
as required by CAA section 107(d)(1), for the 2006 24-hour 
PM2.5 NAAQS. As part of that action, Tacoma, Pierce County 
(partial county designation) became designated as nonattainment for the 
2006 24-hour PM2.5 NAAQS.

IV. What is EPA's analysis of the relevant air quality data?

    EPA has reviewed the ambient air monitoring data for 
PM2.5, consistent with the requirements contained in 40 CFR 
part 50, as recorded in the EPA Air Quality System (AQS) database for 
the Tacoma, Pierce County, 2006 24-hour PM2.5 nonattainment 
area. All data considered have been recorded in the AQS data base, 
certified as meeting quality assurance requirements, and determined to 
have met data completeness requirements. On the basis of that review, 
EPA has concluded that this area attained the 2006 24-hour 
PM2.5 NAAQS during the 2009-2011 monitoring period. Under 
EPA regulations at 40 CFR 50.7: ``The 24-hour primary and secondary 
PM2.5 standards are met when the 98th percentile 24-hour 
concentration, as determined in accordance with appendix N of this 
part, is less than or equal to 35 [mu]g/m\3\.'' The following table 
shows the design values (the metrics calculated in accordance with 40 
CFR part 50, appendix N, for determining compliance with the NAAQS) for 
the 2006 24-hour PM2.5 NAAQS for the years 2009-2011. 
Because the 2009-2011 design value at the Federal Reference Method 
monitor, Tacoma South L Street, is equal to the 2006 24-hour 
PM2.5 NAAQS of 35 [mu]g/m\3\, EPA is proposing to determine 
that the area has monitored attainment for this NAAQS.

\1\ The Tacoma South L Street site is the Federal Reference Method (FRM) monitor used for determining compliance
  with the 2006 PM2.5 NAAQS. PM2.5 AQS data and information is available as part of EPA's AirTrends Site at:
  http://www.epa.gov/airtrends/values.html. More recent 2011 data is included as part of the docket for this
  action.
\2\ The three additional monitors located in the nonattainment area listed above are neither Federal Reference
  Method nor Federal Equivalent Method (FEM) monitors but are included to provide supplementary information.
  Detailed information on how EPA calculated the design values for these monitors is included in the docket for
  this action.

V. What is EPA's proposed action?

    EPA is proposing to determine that the Tacoma, Pierce County area 
has clean data for the 2006 24-hour PM2.5 NAAQS. As provided 
in 40 CFR 51.1004(c), if EPA finalizes this determination, it will 
suspend the requirements for the area to submit an attainment 
demonstration, associated RACM, RFP, contingency measures, and any 
other planning SIP requirements related to the attainment of the 2006 
PM2.5 NAAQS, so long as the area continues to meet the 
standard. EPA is soliciting public comments on the issues discussed in 
this document. These comments will be considered before taking final 
action.

VI. Statutory and Executive Order Reviews

    This action proposes to make an attainment determination based on 
air quality data and would not, if finalized, impose any additional 
requirements. 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 rulemaking that the Tacoma, Pierce 
County PM2.5 nonattainment area has clean data for the 2006 
24-hour PM2.5 standard does not impose substantial direct 
costs on tribal governments or preempt tribal law as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000).
