40 CFR Part 81 

[EPA–R03–OAR–2011–0681; FRL–9458–9] 

Determination of Nonattainment and 

Reclassification of the Baltimore 1997 

8-Hour Ozone Nonattainment Area; MD 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to 

determine that the Baltimore moderate 

8-hour ozone nonattainment area (the 

Baltimore Area) did not attain the 1997 

8-hour ozone national ambient air 

quality standard (NAAQS) by its June 

15, 2011, attainment date. The 

attainment date for moderate ozone 

nonattainment areas was June 15, 2010. 

However, the Baltimore Area qualified 

for a 1-year extension of its attainment 

date. Therefore, EPA extended the area’s 

attainment date to June 15, 2011. This 

proposal is based on EPA’s review of 

complete, quality assured, and certified 

ambient air quality monitoring data for 

the 2008–2010 monitoring period that 

are available in the EPA Air Quality 

System (AQS) database. If EPA finalizes 

this determination, the Baltimore Area 

will be reclassified by operation of law 

as a serious 8-hour ozone nonattainment 

area for the 1997 8-hour ozone standard. 

The serious area attainment date for the 

Baltimore Area would be as 

expeditiously as practicable, but not 

later than June 15, 2013. Once 

reclassified, the State of Maryland must 

submit State Implementation Plan (SIP) 

revisions for the Baltimore Area to meet 

the Clean Air Act (CAA) requirements 

for serious ozone nonattainment areas. 

In this action, EPA is also proposing 

that the State of Maryland submit the 

necessary SIP revisions to EPA by no 

later than September 30, 2012. This 

action is being taken under the CAA.

SUPPLEMENTARY INFORMATION: The 

following outline is provided to aid in 

locating information in this action. 

I. What action is EPA proposing? 

II. What is the background for this action? 

III. Proposed Action 

IV. Statutory and Executive Order Reviews 

I. What action is EPA proposing? 

EPA is proposing to determine that 

the Baltimore Area did not attain the 

1997 8-hour ozone NAAQS by its June 

15, 2011 attainment date. This proposal 

is based on EPA’s review of complete, 

quality assured, and certified ambient 

air quality monitoring data for the 2008– 

2010 monitoring period that are 

available in AQS. If EPA finalizes this 

determination, the Baltimore Area will 

be reclassified by operation of law as a 

serious 8-hour ozone nonattainment 

area for the 1997 8-hour ozone standard. 

The serious area attainment date for the 

Baltimore Area would be as 

expeditiously as practicable, but not 

later than June 15, 2013. (See 40 CFR 

51.903.) Once reclassified, the State of 

Maryland must submit SIP revisions for 

the Baltimore Area that meet the 1997 

8-hour ozone nonattainment 

requirements for serious areas as 

required by the CAA. In this action, EPA 

is also proposing that the State of 

Maryland submit SIP revisions to EPA 

by no later than September 30, 2012 for 

any measures required under the CAA 

for serious ozone nonattainment areas 

which have not already been approved 

into Maryland’s SIP for the Baltimore 

Area. 

II. What is the background for this 

action? 

A. The 1997 8-Hour Ozone NAAQS 

In 1997, EPA revised the health-based 

NAAQS for ozone, setting it at 0.08 

parts per million (ppm) averaged over 

an 8-hour time frame. EPA set the 

8-hour ozone standard based on 

scientific evidence demonstrating that 

ozone causes adverse health effects at 

lower ozone concentrations and over 

longer periods of time, than was 

understood when the pre-existing 

1-hour ozone standard was set. EPA 

determined that the 8-hour standard 

would be more protective of human 

health, especially children and adults 

who are active outdoors, and 

individuals with a pre-existing 

respiratory disease, such as asthma. 

On March 27, 2008 (73 FR 16436), 

EPA promulgated a revised 8-hour 

ozone standard of 0.075 ppm. On 

January 6, 2010, EPA again addressed 


emcdonald on DSK2BSOYB1PROD with PROPOSALS
Federal Register / Vol. 76, No. 170 / Thursday, September 1, 2011 / Proposed Rules 54413 

this 2008 revised standard and proposed 

to set the primary 8-hour ozone 

standard within the range of 0.060 to 

0.070 ppm, rather than at 0.075 ppm. 

EPA is working to complete 

reconsideration of the standard and 

thereafter will proceed with attainment/ 

nonattainment area designations. This 

proposed rulemaking relates only to a 

determination of nonattainment for the 

1997 8-hour ozone standard and is not 

affected by the ongoing process of 

reconsidering the revised 2008 standard. 

This action addresses only the 1997 

8-hour ozone standard of 0.08 ppm, and 

does not address any subsequently 

revised 8-hour ozone standard. 

B. The Baltimore Area 

On April 30, 2004 (69 FR 23951), EPA 

finalized its attainment/nonattainment 

designations for areas across the country 

with respect to the 8-hour ozone 

standard. These actions became 

effective on June 15, 2004. Among those 

nonattainment areas is the Baltimore 

moderate nonattainment area. This area 

includes Baltimore City and Anne 

Arundel, Baltimore, Carroll, Harford, 

and Howard Counties, all in Maryland. 

On March 11, 2011, EPA approved a 

1-year extension of the Baltimore Area’s 

attainment date, from June 15, 2010 to 

June 15, 2011. The extension was based 

on the complete, certified ambient air 

quality data for the 2009 ozone season. 

(See 76 FR 13289.) 

On June 4, 2010, EPA approved a 

Maryland SIP revision to meet the 2002 

base year emissions inventory 

requirement and certain moderate area 

requirements, including reasonable 

further progress (RFP), RFP contingency 

measures, and reasonably available 

control measure (RACM) for the 

Baltimore Area. EPA also approved the 

transportation conformity motor vehicle 

emissions budgets (MVEBs) associated 

with the revision. (See 75 FR 31709.) 

C. Requirement To Determine 

Attainment by the Attainment Date 

Under CAA sections 179(c) and 

181(b)(2), EPA is required to make a 

determination that a nonattainment area 

has attained by its attainment date, and 

publish that determination in the 

Federal Register. Under CAA section 

181(b)(2), which is specific to ozone 

nonattainment areas, if EPA determines 

that an area failed to attain the ozone 

NAAQS by its attainment date, EPA is 

required to reclassify that area to a 

higher classification. 

D. EPA’s Analysis of the Relevant Air 

Quality Data 

Consistent with the requirements 

contained in 40 CFR part 50, EPA has 

reviewed the ozone ambient air 

monitoring data for the monitoring 

period from 2008 through 2010 for the 

Baltimore Area, as recorded in AQS. 

The data that EPA relied on for this 

proposed action is included in the 

docket for this rulemaking, which can 

be viewed at http:// 

www.regulations.gov. 

Under EPA regulations at 40 CFR part 

50, the 1997 8-hour ozone standard is 

attained at a site when the 3-year 

average of the annual fourth-highest 

daily maximum 8-hour average ozone 

concentrations at an ozone monitor is 

less than or equal to 0.08 ppm (i.e., 

0.084 ppm, based on the rounding 

convention in 40 CFR part 50, appendix 

I). This 3-year average is referred to as 

the design value. When the design value 

is less than or equal to 0.084 ppm at 

each monitoring site within the area, 

then the area is meeting the NAAQS. 

Also, the data completeness 

requirement is met when the average 

percent of days with valid ambient 

monitoring data is greater than 90%, 

and no single year has less than 75% 

data completeness as determined in 

appendix I of 40 CFR part 50. 

Table 1 shows the ozone design 

values for each monitor in the Baltimore 

Area for the years 2008–2010. In order 

to attain the NAAQS, all 2008–2010 

design values must be below 0.084 ppm, 

and all monitors must meet the data 

completeness requirements. However, 

monitor number 240251001 in Harford 

County has a design value of 0.089 ppm. 

Therefore, the Baltimore Area has not 

attained the 1997 8-hour ozone NAAQS, 

considering 2008–2010 data.

EPA’s regulations at 40 CFR 51.907 

set forth how a nonattainment area for 

the 1997 8-hour ozone NAAQS can 

qualify for an extension of its attainment 

date. Under 40 CFR 51.907, an area will 

qualify for a 1-year extensions of the 

attainment date if: 

(a) For the first one-year extension, 

the area’s 4th highest daily 8-hour 

average in the attainment year is 0.084 

ppm or less, 

(b) For the second one-year extension, 

the area’s 4th highest daily 8-hour 

value, averaged over both the original 

attainment year and the first extension 

year, is 0.084 ppm or less. 

(c) For purposes of paragraphs (a) and 

(b) of this section, the area’s 4th highest 

daily 8-hour average shall be from the 

monitor with the highest 4th highest 

daily 8-hour average of all the monitors 

that represent that area. 

For the Baltimore Area, the original 

attainment year was 2009 and the first 

extension year was 2010. Table 2, 

below, show the 2009 and 2010 highest 

4th highest daily 8-hour values for the 

Baltimore Area, and the 4th highest 

daily 8-hour values averaged over 2009 

and 2010. The 4th highest daily 8-hour 

values averaged over 2009 and 2010 for 

monitor number 240251001 in Harford 

County is greater than 0.084 ppm (0.090 

ppm). Therefore, the Baltimore Area 

does not qualify for a second extension 

of its attainment date.

E. Determination of Nonattainment/ 

Ambient Air Quality Monitoring Data 

Complete, quality assured, certified 

8-hour ozone air quality monitoring data 

from 2008 through 2010 show that the 

Baltimore Area did not attain the 1997 

8-hour ozone NAAQS by its June 15, 

2011 attainment date. In addition, as 

stated above, the area does not qualify 

for a second 1-year extension of its 

attainment date. 

F. Serious Nonattainment Area SIP 

Requirements 

The SIP requirements for a serious 

nonattainment area are set out in section 

182(c) of the CAA. The requirements for 

serious ozone nonattainment areas 

include, but are not limited to: (1) 

Attainment and reasonable further 

progress demonstrations (CAA section 

182(c)(2), 40 CFR 51.908 and 40 CFR 

51.910); (2) an enhanced monitoring 

program (CAA section 182(c)(1) and 40 

CFR 58.10); (3) an enhanced vehicle 

inspection and maintenance (I/M) 

program (CAA section 182(c)(3) and 40 

CFR 51.350); (4) clean fuel vehicle 

programs (CAA section 182(c)(4)); (5) 

transportation control (CAA section 

182(c)(5)); (6) a 50 ton-per-year (tpy) 

major source threshold (CAA section 

182(c) and 40 CFR 51.165); (7) more 

stringent new source review 

requirements (CAA section 182(c)(6) 

and 40 CFR 51.165); (8) special rules for 

modification of sources (CAA sections 

182(c)(7) and 182(c)(8), and 40 CFR 

51.165); (9) contingency provisions 

(CAA section 182(c)(9)); and (10) 

increased offsets (CAA section 

182(c)(10) and 40 CFR 51.165). See also 

the requirements for serious ozone 

nonattainment areas set forth in section 

182(c) of the CAA. 

Because the Baltimore Area was 

designated as a severe-15 nonattainment 

area under the 1-hour ozone NAAQS (40 

CFR 81.321), the State of Maryland has 

already implemented severe area 

requirements. These measures have 

been approved into Maryland’s SIP for 

the Baltimore Area. The Baltimore Area 

is subject to ‘‘anti-backsliding’’ 

provisions of 40 CFR 51.905(a)(1) as an 

area that was nonattainment for the 

1-hour ozone NAAQS that became a 

nonattainment area for the 1997 8-hour 

ozone NAAQS. Anti-backsliding 

provisions require measures approved 

into Maryland’s SIP for the 1-hour 

ozone NAAQS remain in the SIP for the 

1997 8-hour NAAQS. The applicable 

requirements are specified in 40 CFR 

51.900(f) and include enhanced vehicle 

inspection and maintenance, clean fuel 

fleets, enhanced monitoring, and a 25 

tpy major source threshold for volatile 

organic compounds (VOC) and oxides of 

nitrogen (NOX). In addition, the antibacksliding provisions require that the 

new source review (NSR) requirements 

based on the Baltimore Area’s 1-hour 

severe nonattainment classification 

continue to apply. (See South Coast Air 

Quality Management Dist. v. EPA, 489 

F.3d 1295 (DC Cir. 2007).) 

Because severe area measures are 

more stringent than serious area 

measures, the Baltimore Area already 

meets many of the required serious area 

measures. Table 3, below, summarizes 

the serious nonattainment area 

requirements and their SIP approval 

status. The State of Maryland is only 

required to submit SIP revisions for any 

outstanding serious area measures for 

the 1997 8-hour NAAQS.

III. Proposed Action 

Pursuant to section 181(b)(2) of the 

CAA, EPA is proposing to determine, 

based on certified, quality-assured 

monitoring data for 2008–2010, that the 

Baltimore Area did not attain the 1997 

8-hour ozone standard by its June 15, 

2011 attainment date. If EPA finalizes 

this determination, upon the effective 

date of the final determination, the 

Baltimore Area will be reclassified by 

operation of law as a serious 1997 8- 

hour ozone nonattainment area. 

Pursuant to section 182(i) of the CAA, 

EPA is also proposing the schedule for 

submittal of the SIP revisions required 

for serious areas once the Baltimore 

Area is reclassified. Because the 

Baltimore Area was designated as a 

severe-15 nonattainment area under the 

1-hour ozone NAAQS (40 CFR 81.321), 

the State of Maryland has already 

implemented severe area requirements, 

and these measures have been approved 

into Maryland’s SIP for the Baltimore 

Area. The Baltimore Area is subject to 

‘‘anti-backsliding’’ provisions which 

require that the measures approved into 

Maryland’s SIP for the 1-hour NAAQS 

remain in the SIP. Because severe area 

measures are more stringent than 

serious area measures, the Baltimore 

Area already meets many of the required 

serious area measures. Therefore, the 

State of Maryland is only required to 

submit SIP revisions for any outstanding 

serious area measures for the 1997 8- 

hour ozone NAAQS. EPA is proposing 

that the State of Maryland submit the 

required SIP revisions to EPA by 

September 30, 2012. 

IV. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

CAA 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 CAA. 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 (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 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 Baltimore Area 

did not attain the 1997 8-hour ozone 

NAAQS by its applicable attainment 

date does not have tribal implications as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000), because 

this proposed action 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.
