I. Background

A. Designation and Classification of the Lakeview PM-10 Nonattainment 
Area

    Areas meeting the requirements of section 107(d)(4)(B) of the Clean 
Air Act (CAA) were designated nonattainment for PM-10 by operation of 
law and classified ``moderate'' upon enactment of the 1990 Clean Air 
Act Amendments. See generally 42 U.S.C. 7407(d)(4)(B). In addition, 
pursuant to section 107(d)(3) of the CAA, EPA is authorized to 
redesignate areas as nonattainment for PM-10 on the basis of air 
quality data, planning and control considerations, or any other air 
quality-related considerations that EPA deems appropriate. In December 
1992, the Governor of Oregon requested that, because of recorded 
violations of the 24-hour PM-10 standard in the Lakeview area that 
occurred in 1991 and 1992, the Lakeview area should be reclassified 
nonattainment for PM-10. See 58 FR 34403 (June 25, 1993). Accordingly, 
after notice and an opportunity for public comment, EPA designated the 
Lakeview area nonattainment for PM-10 effective January 20, 1994. See 
58 FR 67334 (December 21, 1993).
    As a newly designated PM-10 nonattainment area, the Lakeview area 
was classified as a moderate nonattainment area by operation of law. 
See CAA section 188(a). Pursuant to section 188(c)(1) of the Act, the 
attainment date for the Lakeview area was to be no later than the end 
of the sixth calendar year after the area was designated nonattainment. 
Because the Lakeview area was designated nonattainment for PM-10 
effective October 25, 1993, the attainment date for the Lakeview area 
is December 31, 1999.

B. How Does EPA Make Attainment Determinations?

    Pursuant to sections 179(c) and 188(b)(2) of the Act, we have the 
responsibility of determining within six months of the applicable 
attainment date whether, based on air quality data, PM-10 nonattainment 
areas attained the PM-10 NAAQS by that date. Determinations under 
section 179(c)(1) of the Act are to be based upon the area's ``air 
quality as of the attainment date.'' Section 188(b)(2) is consistent 
with this requirement.
    Generally, we determine whether an area's air quality is meeting 
the PM-10 NAAQS for purposes of section 179(c)(1) and 188(b)(2) based 
upon data gathered at established state and local air monitoring 
stations (SLAMS) and national air monitoring stations (NAMS) in the 
nonattainment areas and entered into the EPA Aerometric Information 
Retrieval System (AIRS). Data entered into the AIRS has been determined 
to meet federal monitoring requirements (see 40 CFR 50.6, 40 CFR part 
50, appendix J, 40 CFR part 53, 40 CFR part 58, appendix A &B) and may 
be used to determine the attainment status of areas. We will also 
consider air quality data from other air monitoring stations in the 
nonattainment area provided that the stations meet the federal 
monitoring requirements for SLAMS. All data are reviewed to determine 
the area's air quality status in accordance with our guidance at 40 CFR 
part 50, appendix K.
    Attainment of the annual PM-10 standard is achieved when the annual 
arithmetic mean PM-10 concentration over a three-year period (for 
example 1997, 1998, and 1999 for areas with a December 31, 1999 
attainment date) is equal to or less than 50 micrograms per cubic meter 
(ug/m3). Attainment of the 24-hour standard is determined by 
calculating the expected number of days in a year with PM-10 
concentrations greater than 150 ug/m3. The 24-hour standard is attained 
when the expected number of days with levels above 150 ug/m3 (averaged 
over a three-year period) is less than or equal to one. Three 
consecutive years of air quality data are generally required to show 
attainment of the annual and 24-hour standards for PM-10. See 40 CFR 
part 50 and appendix K.

C. What PM-10 Planning has Occurred for the Lakeview PM-10 
Nonattainment Area?

    After the Lakeview area was designated nonattainment, the State of 
Oregon, in cooperation with local officials, developed a control 
strategy that consisted of a residential wood burning combustion 
program. The program included public education and outreach efforts on 
how to burn wood with reduced emissions as well as a wood stove 
curtailment program designed to reduce wood burning during periods of 
adverse meteorology. Oregon submitted the control strategies as a 
revision to the State Implementation Plan (SIP) in 1995. EPA approved 
the SIP revision on September 21, 1999 (64 FR 51051). See 40 CFR 
52.1970 (128).

II. EPA's Action

A. What Does the Air Quality Data Show as of the December 31, 1999 
Attainment Date?

    As discussed above, whether an area has attained the PM-10 NAAQS is 
based exclusively upon measured air quality levels over the most recent 
and complete three calendar year period. See 40 CFR part 50 and 40 CFR 
part 50, appendix K. For an area with a December 31, 1999, attainment 
date, EPA considers data reported for calendar years 1997, 1998, and 
1999.
    The State of Oregon has established and operates one PM-10 SLAMS 
monitoring site in the Lakeview PM-10 nonattainment area near the 
intersection of Center and ``M'' Streets which was operating during 
1997 through the present. In addition, Oregon established monitoring 
sites at the Lakeview Grange Hall and at 336 N. ``L'' street, both of 
which operated in 1998 and 1999. These three monitoring sites meet EPA 
SLAMS network design and siting requirements, set forth at 40 CFR part 
58, appendices D and E. Only the site at Center and ``M'' Streets 
continues to monitor for PM-10.
    There were no reported exceedences of the 24-hour PM-10 NAAQS at 
any of the sites during 1997 through 1999. Therefore, the expected 
exceedence rate is 0.0 for each of the three sites, which shows 
attainment of the 24-hour PM-10 standard. The average of the annual 
average for the years 1997 through 1999 at the Center and ``M'' site, 
the only site for which a three-year average can be calculated, is 21 
ug/m3, which is below the level of the annual PM-10 standard of 50 ug/
m3. Therefore, EPA finds that the Lakeview PM-10 nonattainment area 
attained the PM-10 standards by the attainment date of December 31, 
1999.
    This finding of attainment should not be confused, however, with a 
redesignation to attainment under CAA section 107(d) because Oregon has 
not, for the Lakeview area, submitted a maintenance plan as required 
under section 175(A) of the CAA or met the other CAA requirements for 
redesignations to attainment. The designation status in 40 CFR part 81 
will remain moderate nonattainment for the Lakeview PM-10 nonattainment 
area until such time as Oregon meets the CAA requirements for 
redesignations to attainment.

[[Page 38950]]

B. Does the More Recent Air Quality Data Also Show Attainment?

    The attainment date for the Lakeview PM-10 nonattainment area is 
December 31, 1999, and the air quality data used to judge attainment by 
that date includes all data collected in calendar years 1997, 1998, and 
1999. Beginning in January 2000 the Lakeview Grange Hall and 336 N. 
``L'' street sites discontinued operation. EPA also reviewed the air 
quality data collected at the Center and ``M'' monitoring site through 
2000. There were no exceedences of the 24-hour standard in 2000 at that 
site. Likewise, the annual average from the Center and ``M'' site was 
20 ug/m3, which is below the level of the annual standard. There was 
insufficient data to determine an annual average from the other two 
sites.

III. Administrative Requirements

    Under Executive Order 12866, ``Regulatory Planning and Review'' (58 
FR 51735, October 4, 1993), this action is not a ``significant 
regulatory action'' and therefore is not subject to review by the 
Office of Management and Budget. For this reason, this action is also 
not subject to Executive Order 13211, ``Actions Concerning Regulations 
That Significantly Affect Energy Supply, Distribution or Use'' (66 FR 
28355, May 22, 2001). Under the Regulatory Flexibility Act (5 U.S.C. 
601 et seq.), the Administrator certifies that this action will not 
have a significant economic impact on a substantial number of small 
entities because it merely makes a determination based on air quality 
data and does not impose any requirements. This action does not contain 
any unfunded mandates and does not significantly or uniquely affect 
small governments, as described in the Unfunded Mandates Reform Act of 
1995 (Pub. L. 104-4) because it does not impose any enforceable duties.
    This action also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175, 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000). This action also does not have Federalism 
implications because it will not have substantial direct effects on the 
States, on the relationship between the national government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government, as specified in Executive Order 13132, 
``Federalism'' (64 FR 43255, August 10, 1999). The action merely makes 
a determination based on air quality data and does not impose any 
requirements and therefore does not alter the relationship or the 
distribution of power and responsibilities between the State and the 
Federal government established in the Clean Air Act.
    This action also is not subject to Executive Order 13045, 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997) because it is not a significant 
regulatory action under Executive Order 12866.
    This action does not involve technical standards. Thus, the 
requirements of section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. In addition, 
this action does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et 
seq.).
    Because this in not a ``major'' rule as defined by 5 U.S.C. 804(2), 
EPA will not submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
this rule in the Federal Register, as specified in the Congressional 
Review Act, 5 U.S.C. 801 et seq.
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 24, 2001. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review may be filed, and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements. See CAA section 307(b)(2).
