ACTION: Proposed rule. SUMMARY: The EPA is proposing to approve revisions to the Texas State Implementation Plan (SIP) that amend 30 TAC Chapter 117, Control of Air Pollution from Nitrogen Compounds. On March 10, 2009, the State of Texas submitted a SIP revision containing amendments to the Beaumont-Port Arthur (BPA) 8-Hour Ozone Nonattainment Area Major Source rules, the Houston-Galveston-Brazoria (HGB) 8-Hour Ozone Nonattainment Area Major Source rules, and the HGB 8-Hour Ozone Nonattainment Area Minor Source rules. These revisions will result in additional flexibility and consistency in the current stationary reciprocating internal combustion engine and gas turbine monitoring specifications found in Chapter 117 by allowing for an output-based option for monitoring nitrogen oxides (NOX) emissions. This additional option is expected to be equally effective as totalizing fuel flow meters in the monitoring of NOX emissions at major stationary sources in the BPA 8-hour ozone nonattainment area and at both major and minor sources in the HGB 8-hour ozone nonattainment area. The EPA is proposing to approve these revisions pursuant to section 110 of the Federal Clean Air Act (CAA). DATES: Written comments must be received on or before August 31, 2009. ADDRESSES: Comments may be mailed to Mr. Guy Donaldson, Chief, Air Planning Section (6PD–L), Environmental Protection Agency, 1445 Ross Avenue, Suite 1200, Dallas, Texas 75202–2733. Comments may also be submitted electronically or through hand delivery/ courier by following the detailed instructions in the Addresses section of the direct final rule located in the rules section of this Federal Register. FOR FURTHER INFORMATION CONTACT: Dayana Medina, Air Planning Section (6PD–L), Multimedia Planning and Permitting Division, U.S. EPA, Region 6, 1445 Ross Avenue, Dallas, Texas 75202– 2733, telephone (214) 665–7241; fax number 214–665–7263; e-mail address medina.dayana@epa.gov. VerDate Nov<24>2008 16:28 Jul 30, 2009 Jkt 217001 In the final rules section of this Federal Register, EPA is approving the State’s SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule, which is located in the rules section of this Federal Register. SUPPLEMENTARY INFORMATION: ENVIRONMENTAL PROTECTION AGENCY Dated: July 21, 2009.

IV. What Is EPA’s Analysis of the Relevant Air Quality Data? V. Proposed Action VI. Statutory and Executive Order Reviews jlentini on DSKJ8SOYB1PROD with PROPOSALS I. What Action Is EPA Taking? EPA is proposing to determine that the Baltimore and the Maryland portion of the Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas have clean data for the 1997 PM2.5 NAAQS. This determination is based upon quality assured, quality controlled, and certified ambient air monitoring data showing that these areas have monitored attainment of the 1997 PM2.5 NAAQS based on the 2006–2008 data. In addition, quality controlled and quality assured monitoring data for 2009 that are available in the EPA AQS database, but not yet certified, show that these areas continue to meet the 1997 PM2.5 NAAQS. VerDate Nov<24>2008 16:28 Jul 30, 2009 Jkt 217001 II. What Is the Effect of This Action? If this determination is made final, under the provisions of EPA’s PM2.5 implementation rule (see 40 CFR section 51.1004(c)), the requirements for the Baltimore and the Maryland portion of the Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS would be suspended for so long as each area continues to meet the 1997 PM2.5 NAAQS. As further discussed below, the proposed determination for the Baltimore, MD and for the Maryland portion of the Hagerstown-Martinsburg, MD-WV nonattainment areas would: (1) Suspend the requirements to submit for each area an attainment demonstration, associated reasonably available control measures (RACM) (including reasonably available control technologies (RACT)), a reasonable further progress (RFP) plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS; (2) continue until such time, if any, that EPA subsequently determines that each area have violated the 1997 PM2.5 NAAQS; (3) be separate from, and not influence or otherwise affect, any future designation determination or requirements for the Baltimore and Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas based on the 2006 PM2.5 NAAQS; and (4) remain in effect regardless of whether EPA designates these areas as nonattainment for purposes of the 2006 PM2.5 NAAQS. Furthermore, as described below, any such final determinations would not be equivalent to the redesignation of these areas to attainment based on the 1997 PM2.5 NAAQS. If this rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the Federal Register, that the areas have violated the 1997 PM2.5 NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR section 51.1004(c), would no longer exist, and these areas would thereafter have to address the pertinent requirements. The determination that EPA proposes with this Federal Register notice, that the air quality data shows attainment of the 1997 PM2.5 NAAQS, is not equivalent to the redesignation of these areas to attainment. This proposed action, if finalized, would not constitute a redesignation to attainment under section 107(d)(3) of the Clean Air Act PO 00000 Frm 00046 Fmt 4702 Sfmt 4702 (CAA), because we would not yet have an approved maintenance plan for these areas as required under section 175A of the CAA, nor a determination that these areas have met the other requirements for redesignation. The designation status of these areas would remain nonattainment for the 1997 PM2.5 NAAQS until such time as EPA determines that these areas meet the CAA requirements for redesignation to attainment. This proposed action, if finalized, is limited to a determination that the Baltimore and the Maryland portion of the Hagerstown-Martinsburg MD-WV PM2.5 nonattainment areas have clean data for the 1997 PM2.5 NAAQS. The 1997 PM2.5 NAAQS became effective on July 18, 1997 (62 FR 36852) and are set forth at 40 CFR section 50.7. The 2006 PM2.5 NAAQS, which became effective on December 18, 2006 (71 FR 61144) are set forth at 40 CFR section 50.13. EPA is currently in the process of making designation determinations, as required by CAA section 107(d)(2), for the 2006 PM2.5 NAAQS. At this point, EPA has not made any designation determination for the Baltimore and HagerstownMartinsburg MD-WV PM2.5 nonattainment areas based on the 2006 PM2.5 NAAQS. This proposed determination, 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 2006 PM2.5 NAAQS for the Baltimore and HagerstownMartinsburg, MD-WV PM2.5 nonattainment areas. Conversely, any future designation determination of the Baltimore and Hagerstown-Martinsburg, MD-WV nonattainment areas, based on the 2006 PM2.5 NAAQS, will not have any effect on the determination proposed by this notice. If this proposed determination is made final and the Baltimore and the Maryland portion of the HagerstownMartinsburg, MD-WV nonattainment areas continue to demonstrate attainment with the 1997 PM2.5 NAAQS, the requirements for the nonattainment areas to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS would remain suspended, regardless of whether EPA designates these areas as nonattainment areas for purposes of the 2006 PM2.5 NAAQS. Once these areas are designated for the 2006 NAAQS, they will have to meet all applicable requirements for that designation. E:\FR\FM\31JYP1.SGM 31JYP1 38163 Federal Register / Vol. 74, No. 146 / Friday, July 31, 2009 / Proposed Rules III. What Is the Background for This Action? On July 18, 1997 (62 FR 36852), EPA established a health-based PM2.5 NAAQS at 15.0 micrograms per cubic meter (μg/m3) based on a 3-year average of annual mean PM2.5 concentrations, and a twenty-four hour standard of 65 μg/m3 based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA established the standards based on significant evidence and numerous health studies demonstrating that serious health effects are associated with exposures to particulate matter. The process for designating areas following promulgation of a new or revised NAAQS is contained in section 107(d)(1) of the CAA. EPA and State air quality agencies initiated the monitoring process for the 1997 PM2.5 NAAQS in 1999, and developed all air quality monitors by January 2001. 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 Baltimore and Hagerstown-Martinsburg, MD-WV nonattainment areas were designated nonattainment for the 1997 PM2.5 NAAQS (see 40 CFR part 81). 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 and recorded in the EPA AQS database for the Baltimore and Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas from 2006 through the present time. On the basis of that review, EPA has concluded that these areas meet the 1997 PM2.5 NAAQS based on the 2006–2008 data. In addition, quality controlled and quality assured monitoring data for 2009 that are available in the EPA AQS database, but not yet certified, show these areas continue to attain the 1997 PM2.5 NAAQS. Under EPA regulations at 40 CFR Part 50, section 50.7: (1) The 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 μg/m3. (2) The 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 65 μg/m3. Table 1.a shows the design values for the 1997 Annual PM2.5 NAAQS for the Baltimore nonattainment area monitors for the years 2006–2008. Table 1.b shows the design values for the 1997 Annual PM2.5 NAAQS for the Hagerstown-Martinsburg, MD-WV nonattainment area monitors for the years 2006–2008.

What’s EPA’s Proposed Action? EPA is proposing to determine that the Baltimore and the Maryland portion of the Hagerstown-Martinsburg, MD-WV nonattainment areas for the 1997 PM2.5 NAAQS have clean data for the 1997 PM2.5 NAAQS. As provided in 40 CFR section 51.1004(c), if EPA finalizes this determination, it would suspend the requirements for these areas to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS so long as these areas continues to meet the 1997 PM2.5 NAAQS. VI. What Are the Statutory and Executive Order Reviews? Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the VerDate Nov<24>2008 16:28 Jul 30, 2009 Jkt 217001 1997 24-Hour attainment standard AQS site ID 24–043–0009 54–003–0003 provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does 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 (Public Law 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); PO 00000 Frm 00048 Fmt 4702 Sfmt 4702 2005–2007 design values 65 65 30 31 • 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 Clean Air Act; 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 determination that the Maryland portion of the Hagerstown-Martinsburg and the Baltimore nonattainment areas have clean data for the 1997 PM2.5 standard 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.

Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Determination of Clean Data for the 1997 Fine Particulate 
Matter Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to determine that the Baltimore, Maryland and 
Hagerstown-Martinsburg, Maryland (MD)-West Virginia (WV) nonattainment 
areas for the 1997 fine particulate matter (PM2.5) National 
Ambient Air Quality Standard (NAAQS) have clean data for the 1997 
PM2.5 NAAQS. This proposed determination is based upon 
quality assured, quality controlled, and certified ambient air 
monitoring data showing that these areas have monitored attainment of 
the 1997 PM2.5 NAAQS based on the 2006-2008 data. In 
addition, quality controlled and quality assured monitoring data for 
2009 that are available in the EPA Air Quality System (AQS) database, 
but not yet certified, show that these areas continue to meet the 1997 
PM2.5 NAAQS. If this proposed determination is made final, 
the requirements for these areas to submit an attainment demonstration, 
associated reasonably available measures, a reasonable further progress 
plan, contingency measures, and other planning State Implementation 
Plans (SIPs) related to attainment of the standard shall be suspended 
for so long as each of these areas continue to meet the 1997 
PM2.5 NAAQS.

I. What Action Is EPA Taking?

    EPA is proposing to determine that the Baltimore and the Maryland 
portion of the Hagerstown-Martinsburg, MD-WV PM2.5 
nonattainment areas have clean data for the 1997 PM2.5 
NAAQS. This determination is based upon quality assured, quality 
controlled, and certified ambient air monitoring data showing that 
these areas have monitored attainment of the 1997 PM2.5 
NAAQS based on the 2006-2008 data. In addition, quality controlled and 
quality assured monitoring data for 2009 that are available in the EPA 
AQS database, but not yet certified, show that these areas continue to 
meet the 1997 PM2.5 NAAQS.

II. What Is the Effect of This Action?

    If this determination is made final, under the provisions of EPA's 
PM2.5 implementation rule (see 40 CFR section 51.1004(c)), 
the requirements for the Baltimore and the Maryland portion of the 
Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas to 
submit an attainment demonstration, associated reasonably available 
control measures, a reasonable further progress plan, contingency 
measures, and any other planning SIPs related to attainment of the 1997 
PM2.5 NAAQS would be suspended for so long as each area 
continues to meet the 1997 PM2.5 NAAQS.
    As further discussed below, the proposed determination for the 
Baltimore, MD and for the Maryland portion of the Hagerstown-
Martinsburg, MD-WV nonattainment areas would: (1) Suspend the 
requirements to submit for each area an attainment demonstration, 
associated reasonably available control measures (RACM) (including 
reasonably available control technologies (RACT)), a reasonable further 
progress (RFP) plan, contingency measures, and any other planning SIPs 
related to attainment of the 1997 PM2.5 NAAQS; (2) continue 
until such time, if any, that EPA subsequently determines that each 
area have violated the 1997 PM2.5 NAAQS; (3) be separate 
from, and not influence or otherwise affect, any future designation 
determination or requirements for the Baltimore and Hagerstown-
Martinsburg, MD-WV PM2.5 nonattainment areas based on the 
2006 PM2.5 NAAQS; and (4) remain in effect regardless of 
whether EPA designates these areas as nonattainment for purposes of the 
2006 PM2.5 NAAQS. Furthermore, as described below, any such 
final determinations would not be equivalent to the redesignation of 
these areas to attainment based on the 1997 PM2.5 NAAQS.
    If this rulemaking is finalized and EPA subsequently determines, 
after notice-and-comment rulemaking in the Federal Register, that the 
areas have violated the 1997 PM2.5 NAAQS, the basis for the 
suspension of the specific requirements, set forth at 40 CFR section 
51.1004(c), would no longer exist, and these areas would thereafter 
have to address the pertinent requirements.
    The determination that EPA proposes with this Federal Register 
notice, that the air quality data shows attainment of the 1997 
PM2.5 NAAQS, is not equivalent to the redesignation of these 
areas to attainment. This proposed action, if finalized, would not 
constitute a redesignation to attainment under section 107(d)(3) of the 
Clean Air Act (CAA), because we would not yet have an approved 
maintenance plan for these areas as required under section 175A of the 
CAA, nor a determination that these areas have met the other 
requirements for redesignation. The designation status of these areas 
would remain nonattainment for the 1997 PM2.5 NAAQS until 
such time as EPA determines that these areas meet the CAA requirements 
for redesignation to attainment.
    This proposed action, if finalized, is limited to a determination 
that the Baltimore and the Maryland portion of the Hagerstown-
Martinsburg MD-WV PM2.5 nonattainment areas have clean data 
for the 1997 PM2.5 NAAQS. The 1997 PM2.5 NAAQS 
became effective on July 18, 1997 (62 FR 36852) and are set forth at 40 
CFR section 50.7. The 2006 PM2.5 NAAQS, which became 
effective on December 18, 2006 (71 FR 61144) are set forth at 40 CFR 
section 50.13. EPA is currently in the process of making designation 
determinations, as required by CAA section 107(d)(2), for the 2006 
PM2.5 NAAQS. At this point, EPA has not made any designation 
determination for the Baltimore and Hagerstown-Martinsburg MD-WV 
PM2.5 nonattainment areas based on the 2006 PM2.5 
NAAQS. This proposed determination, 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 2006 PM2.5 
NAAQS for the Baltimore and Hagerstown-Martinsburg, MD-WV 
PM2.5 nonattainment areas. Conversely, any future 
designation determination of the Baltimore and Hagerstown-Martinsburg, 
MD-WV nonattainment areas, based on the 2006 PM2.5 NAAQS, 
will not have any effect on the determination proposed by this notice.
    If this proposed determination is made final and the Baltimore and 
the Maryland portion of the Hagerstown-Martinsburg, MD-WV nonattainment 
areas continue to demonstrate attainment with the 1997 PM2.5 
NAAQS, the requirements for the nonattainment areas to submit an 
attainment demonstration, associated reasonably available control 
measures, a reasonable further progress plan, contingency measures, and 
any other planning SIPs related to attainment of the 1997 
PM2.5 NAAQS would remain suspended, regardless of whether 
EPA designates these areas as nonattainment areas for purposes of the 
2006 PM2.5 NAAQS. Once these areas are designated for the 
2006 NAAQS, they will have to meet all applicable requirements for that 
designation.

III. What Is the Background for This Action?

    On July 18, 1997 (62 FR 36852), EPA established a health-based 
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, and a twenty-four hour standard of 65 [mu]g/m\3\ based 
on a 3-year average of the 98th percentile of 24-hour concentrations. 
EPA established the standards based on significant evidence and 
numerous health studies demonstrating that serious health effects are 
associated with exposures to particulate matter. The process for 
designating areas following promulgation of a new or revised NAAQS is 
contained in section 107(d)(1) of the CAA. EPA and State air quality 
agencies initiated the monitoring process for the 1997 PM2.5 
NAAQS in 1999, and developed all air quality monitors by January 2001. 
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 Baltimore and Hagerstown-Martinsburg, MD-WV nonattainment areas 
were designated nonattainment for the 1997 PM2.5 NAAQS (see 
40 CFR part 81).

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 and recorded in the EPA AQS database for the Baltimore and 
Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas from 
2006 through the present time. On the basis of that review, EPA has 
concluded that these areas meet the 1997 PM2.5 NAAQS based 
on the 2006-2008 data. In addition, quality controlled and quality 
assured monitoring data for 2009 that are available in the EPA AQS 
database, but not yet certified, show these areas continue to attain 
the 1997 PM2.5 NAAQS.
    Under EPA regulations at 40 CFR Part 50, section 50.7:
    (1) The 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 [mu]g/m\3\.
    (2) The 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 
65 [mu]g/m\3\.

    EPA's reviews of these data indicate that the Baltimore, MD and 
Hagerstown-Martinsburg, MD-WV PM2.5 nonattainment areas have 
met and continue to meet the 1997 PM2.5 NAAQS. EPA is 
soliciting public comments on the issues discussed in this document. 
These comments will be considered before taking final action. Please 
note that if EPA received adverse comment on an amendment, paragraph, 
or section of this rule and if that provision may be severed from the 
remainder of the rule, EPA may adopt as final those provisions of the 
rule that are not the subject of an adverse comment.

V. What's EPA's Proposed Action?

    EPA is proposing to determine that the Baltimore and the Maryland 
portion of the Hagerstown-Martinsburg, MD-WV nonattainment areas for 
the 1997 PM2.5 NAAQS have clean data for the 1997 
PM2.5 NAAQS. As provided in 40 CFR section 51.1004(c), if 
EPA finalizes this determination, it would suspend the requirements for 
these areas to submit an attainment demonstration, associated 
reasonably available control measures, a reasonable further progress 
plan, contingency measures, and any other planning SIPs related to 
attainment of the 1997 PM2.5 NAAQS so long as these areas 
continues to meet the 1997 PM2.5 NAAQS.

VI. What Are the Statutory and Executive Order Reviews?

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely proposes to approve state law as 
meeting Federal requirements and does 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 (Public Law 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 Clean Air Act; 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 determination that the Maryland portion 
of the Hagerstown-Martinsburg and the Baltimore nonattainment areas 
have clean data for the 1997 PM2.5 standard 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.
