Approval and Promulgation of Air Quality Implementation Plans; Maryland; Determination of Attainment of the 1997 8-Hour Ozone National Ambient Air Quality Standard for the Baltimore, Maryland Serious Nonattainment Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to make a determination that the Baltimore, Maryland Serious Nonattainment Area (Baltimore Area) has attained the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). This proposed determination is based upon complete, quality-assured, and certified ambient air monitoring data that shows the Area has monitored attainment of the 1997 8-hour ozone NAAQS for the 2012-2014 monitoring period. If this proposal becomes final, the requirement for this Area to submit an attainment demonstration, reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures related to attainment of the 1997 8-hour ozone NAAQS shall be suspended for so long as the Area continues to attain the 1997 8-hour ozone NAAQS. This action does not constitute a redesignation to attainment. The Baltimore Area will remain nonattainment for the 1997 8-hour ozone NAAQS until such time as EPA determines that the Baltimore Area meets the Clean Air Act (CAA) requirements for redesignation to attainment, including an approved maintenance plan. This action is being taken under the CAA.

SUPPLEMENTARY INFORMATION:

Background
On July 18, 1997, EPA revised the health-based NAAQS for ozone based on 8-hour average concentrations. 62 FR 38856. The 8-hour averaging period replaced the previous 1-hour averaging period, and the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm. Id. On April 30, 2004 (69 FR 23858), EPA finalized its attainment/nonattainment designations for areas across the country for the 1997 8-hour ozone NAAQS. These actions became effective on June 15, 2004. Among those nonattainment areas was the Baltimore Area (specifically, Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Harford County, and Howard County), which was designated as a moderate ozone nonattainment area. Id. Later, the Baltimore Area was reclassified as a serious nonattainment area for the 1997 ozone NAAQS. 77 FR 4901 (February 1, 2012). See 40 CFR 81.321. Air quality monitoring data from the 2012-2014 monitoring period indicate that the Baltimore Area is now attaining the 1997 8-hour ozone NAAQS.
Under the provisions of EPA's ozone implementation rule (40 CFR 51.918), if EPA issues a determination that an area is attaining the relevant standard (through a rulemaking that includes public notice and comment), it will suspend the area's obligations to submit an attainment demonstration, RACM, RFP, contingency measures and other planning requirements related to attainment of the 1997 8-hour ozone NAAQS for as long as the area continues to attain the standard. This suspension remains in effect until such time, if ever, that EPA (i) redesignates the area to attainment at which time those requirements no longer apply, or (ii) subsequently determines that the area has violated the 1997 8-hour ozone NAAQS. Although these requirements are suspended, EPA is not precluded
Page 15712
from acting upon these elements at any time if submitted to EPA for review and approval. The determination of attainment is not equivalent to a redesignation under section 107(d)(3) of the CAA. The designation status of the Baltimore Area will remain nonattainment for the 1997 8-
hour ozone NAAQS until such time as EPA determines that the Baltimore Area meets the CAA requirements for redesignation to attainment, including an approved maintenance plan. Additionally, the determination of attainment is separate from, and does not influence or otherwise affect, any future designation determination or requirements for the Baltimore Area based on any new or revised ozone NAAQS, and it remains in effect regardless of whether EPA designates the Baltimore Area as a nonattainment area for purposes of any new or revised ozone NAAQS.

EPA's Evaluation
For ozone, an area may be considered to be attaining the 1997 8-
hour ozone NAAQS if there are no violations, as determined in accordance with 40 CFR part 50, based on three complete, consecutive calendar years of quality-assured ambient air monitoring data. Under EPA regulations at 40 CFR part 50, the 1997 8-hour ozone standard is attained when the 3-year average of the annual fourth-highest daily maximum 8-hour average ozone concentration at an ozone monitor is less than or equal to 0.08 ppm. This 3-year average is referred to as the design value. When the design value is less than or equal to 0.084 ppm (based on the rounding convention in 40 CFR part 50, Appendix I) at each monitor within the area, then the area is attaining the NAAQS. Also, the data completeness requirement is met when the average percent of days with valid ambient monitoring data is greater than or equal to 90 percent (%), and no single year has less than 75% data completeness as determined in Appendix I of 40 CFR part 50. The data must be collected and quality-assured in accordance with 40 CFR part 58, and recorded in the EPA Air Quality System (AQS).
EPA has reviewed the complete, quality-assured and certified ozone ambient air monitoring data for the monitoring period for 2012-2014 for the Baltimore Area. The design values for each monitor for the years 2012-2014 are less than or equal to 0.084 ppm, and all monitors meet the data completeness requirements (see Table 1). Based on this 2012-
2014 data from the AQS database and consistent with the requirements contained in 40 CFR part 50, EPA has concluded that this Area attained the 1997 8-hour ozone NAAQS.

Proposed Action
EPA is proposing to make a determination that the Baltimore Area has attained the 1997 8-hour ozone NAAQS. This proposed determination is based upon complete, quality-assured, and certified ambient air monitoring data that show the Area has monitored attainment of the 1997 8-hour ozone NAAQS for the 2012-2014 monitoring period. Once this proposal is final, the requirement for this Area to submit an attainment demonstration, RACM, a RFP plan, contingency measures, and other planning requirements related to attainment of the 1997 8-hour ozone NAAQS shall be suspended for so long as the Area continues to attain the 1997 8-hour ozone NAAQS. Although these requirements are suspended, EPA is not precluded from acting upon these elements at any time if submitted to EPA for review and approval. Finalizing this determination does not constitute a redesignation of the Baltimore Area to attainment for the 1997 8-hour ozone NAAQS under CAA section 107(d)(3). This determination of attainment also does not involve approving any maintenance plan for the Baltimore Area and does not determine that the Area has met all the requirements for redesignation under the CAA, including that the attainment be due to permanent and enforceable measures. Therefore, the designation status of the Baltimore Area will remain nonattainment for the 1997 8-hour ozone NAAQS until such time as EPA takes final rulemaking action to determine that such Area meets the CAA requirements for redesignation to attainment. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

Statutory and Executive Order Reviews
This action proposes to make an attainment determination based on air quality data and would, if finalized, result in the suspension of certain Federal requirements and would not 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 (Public Law 104-4);
Page 15713
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 rule, concerning a determination of attainment for the 1997 8-hour ozone NAAQS for the Baltimore Area, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the State Implementation Plan (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.
