Air Quality Designations for the 2010 

Primary Nitrogen Dioxide (NO2) 

National Ambient Air Quality 

Standards 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This rule establishes air 

quality designations for all areas in the 

United States for the 2010 Primary 

Nitrogen Dioxide (NO2) National 

Ambient Air Quality Standards 

(NAAQS). Based on air quality 

monitoring data, the EPA is issuing this 

rule to designate all areas of the country 

as ‘‘unclassifiable/attainment’’ for the 

2010 NO2 NAAQS. The EPA is 

designating areas as ‘‘unclassifiable/ 

attainment’’ to mean that available 

information does not indicate that the 

air quality in these areas exceeds the 

2010 NO2 NAAQS. 

DATES: The effective date of this rule is 

February 29, 2012. 

ADDRESSES: The EPA has established a 

docket for this action under Docket ID

II. What is the purpose of this action? 

The purpose of this action is to 

promulgate and announce initial area 

designations for all areas of the country 

for the 2010 NO2 NAAQS based on 

available information, in accordance 

with the requirements of the Clean Air 

Act (CAA). The list of all areas being 

designated in each state, and the 

boundaries of each area, appear in the 

tables at the end of this final rule. The 

EPA has been working closely with the 

states involved in these designations 

and several steps have been taken to 

announce that this rule is available. The 

EPA has posted the notice on several 

EPA Web sites. 

This notice identifies all areas of the 

United States (U.S.) as being designated 

as ‘‘unclassifiable/attainment’’ for the 

2010 NO2 NAAQS. The basis for 

designating these areas as 

‘‘unclassifiable/attainment’’ is 

monitored air quality data from calendar 

years 2008–2010 indicating no 

violations of the NAAQS. 

The EPA and state agencies are 

currently working to establish an 

expanded network of NO2 monitors, 

expected to be deployed in 2013. Once 

3 years of air quality data have been 

collected from the expanded network, 

the EPA will be able to evaluate NO2 air 

quality in additional locations. 

III. What is nitrogen dioxide? 

NO2 is a reddish-brown, highly 

reactive gas that is formed in the 

ambient air through the oxidation of 

nitric oxide (NO). Nitrogen oxides 

(NOX) is the term used to describe the 

sum of NO, NO2, and other oxides of 

nitrogen. A variety of NOX compounds 

and their transformation products occur 

both naturally and as a result of human 

activities. Anthropogenic (i.e., 

manmade) emissions of NOX account for 

a large majority of all nitrogen inputs to 

the environment. The major sources of 

anthropogenic NOX emissions are hightemperature combustion processes, such 

as those occurring in automobiles and 

power plants. Most NOX from 

combustion sources (about 95 percent) 

are emitted as NO, which is readily 

converted to NO2 in the environment; 

the remainder is emitted largely as NO2. 

Natural sources of NOX are lightning, 

biological and abiological processes in 

soil, and stratospheric intrusion. 

IV. What are the health concerns 

addressed by the NO2 standards? 

Current scientific evidence links 

short-term NO2 exposures, ranging from 

30 minutes to 24 hours, with an array 

of adverse respiratory effects including 

increased asthma symptoms, more 

difficulty controlling asthma, and an 

increase in respiratory illnesses and 

symptoms. Studies also show a 

connection between short-term 

exposure and increased visits to 

emergency departments and hospital 

admissions for respiratory illnesses, 

particularly in populations including 

children, the elderly, and asthmatics. 

The EPA’s NAAQS for NO2 is 

designed to protect against exposure to 

the entire group of NOX. NO2 is the 

component of greatest concern and is 

used as the indicator for the larger group 

of NOX. (See 75 FR 6474.) 

V. What are the CAA requirements for 

air quality designations and what 

action has the EPA taken to meet these 

requirements? 

After the promulgation of a new or 

revised NAAQS, the EPA is required to 

designate areas as nonattainment, 

attainment, or unclassifiable, pursuant 

to section 107(d)(1) of the CAA. The 

Administrator signed a final rule 

revising the NO2 NAAQS on January 22, 

2010, which was published in the 

Federal Register on February 9, 2010, 

and became effective April 12, 2010. 

Based on the Administrator’s review of 

the scientific evidence, including 

numerous studies published since the 

last review of the NO2 NAAQS, and 

taking into consideration the comments 

expressed by the Clean Air Scientific 

Advisory Committee and the public, the 

Administrator set a new 1-hour NO2

standard at the level of 100 parts per 

billion (ppb). In addition to establishing 

an averaging time and level, the 

Administrator also set a new form for 

the standard. The form for the 1-hour 

NO2 standard is the 3-year average of 

the 98th percentile of the annual 

distribution of daily maximum 1-hour 

average concentrations. The rule also 

retained, with no change, the current 

annual average NO2 standard of 53 ppb. 

The rule also set new requirements for 

the placement of NO2 monitors. The 

EPA and state agencies are currently 

working to establish an expanded 

network of NO2 monitors, expected to 

be deployed in 2013. NO2

concentrations near major roads are 

appreciably higher than those measured 

at monitors in the current network. 

Monitoring studies indicate that nearroad (within about 50 meters) 

concentrations of NO2 can be 30 to 100 

percent higher than concentrations 

away from major roads. 

The CAA requires the EPA to 

complete the initial area designation 

process within 2 years of promulgating 

a new or revised NAAQS. However, if 

mstockstill on DSK4VPTVN1PROD with RULES

9534 Federal Register / Vol. 77, No. 33 / Friday, February 17, 2012 / Rules and Regulations 

1This view was confirmed in Catawba County v. 

EPA, 571 F.3d 20 (DC Cir. 2009). 

the Administrator has insufficient 

information to make these designations 

within that time frame, the EPA has the 

authority to extend the designation 

process by up to 1 additional year. 

By not later than 1 year after the 

promulgation of a new or revised 

NAAQS, each state governor is required 

to recommend air quality designations, 

including the appropriate boundaries 

for areas, to the EPA. The EPA reviews 

those state recommendations and is 

authorized to make any modifications 

the Administrator deems necessary. The 

statute does not define the term 

‘‘necessary,’’ but the EPA interprets this 

to authorize the Administrator to 

modify designations that did not meet 

the statutory requirements or were 

otherwise inconsistent with the facts or 

analysis deemed appropriate by the 

EPA. If the EPA is considering 

modifications to a state’s initial 

recommendation, the EPA is required to 

notify the state of any such intended 

modifications to its recommendation 

not less than 120 days prior to the EPA’s 

promulgation of the final designation. If 

the state does not agree with the EPA’s 

intended modification, it then has an 

opportunity to respond to the EPA and 

to demonstrate why it believes the 

modification proposed by the EPA is 

inappropriate. Even if a state fails to 

provide any recommendation for an 

area, in whole or in part, the EPA still 

must promulgate a designation that the 

Administrator deems appropriate. 

Section 107(d)(1)(A)(i) of the CAA 

defines a nonattainment area as any area 

that does not meet an ambient air 

quality standard or that is contributing 

to ambient air quality in a nearby area 

that does not meet the standard. If an 

area meets either prong of this 

definition, then the EPA is obligated to 

designate the area as ‘‘nonattainment.’’ 

Section 107(d)(1)(A)(iii) provides that 

any area that the EPA cannot designate 

on the basis of available information as 

meeting or not meeting the standards 

should be designated as 

‘‘unclassifiable.’’ 

The EPA believes that section 107(d) 

provides the agency with discretion to 

determine how best to interpret the 

terms in the definition of a 

nonattainment area (e.g., ‘‘contributes 

to’’ and ‘‘nearby’’) for a new or revised 

NAAQS, given considerations such as 

the nature of a specific pollutant, the 

types of sources that may contribute to 

violations, the form of the standards for 

the pollutant, and other relevant 

information. In particular, the EPA 

believes that the statute does not require 

the agency to establish bright line tests 

or thresholds for what constitutes 

‘‘contribution’’ or ‘‘nearby’’ for purposes 

of designations.1

Similarly, the EPA believes that the 

statute permits the EPA to evaluate the 

appropriate application of the term 

‘‘area’’ to include geographic areas 

based upon full or partial county 

boundaries, and contiguous or noncontiguous areas, as may be appropriate 

for a particular NAAQS. For example, 

section 107(d)(1)(B)(ii) explicitly 

provides that the EPA can make 

modifications to designation 

recommendations for an area ‘‘or 

portions thereof,’’ and, under section 

107(d)(1)(B)(iv), a designation remains 

in effect for an area ‘‘or portion thereof’’ 

until the EPA redesignates it. 

Designation activities for federallyrecognized tribes are covered under the 

authority of section 301(d) of the CAA. 

This provision of the CAA authorizes 

the EPA to treat eligible tribes in a 

similar manner as states. Pursuant to 

section 301(d)(2), we promulgated 

regulations, known as the Tribal 

Authority Rule (TAR), on February 12, 

1999. See 63 FR 7254, codified at 40 

CFR 49 (1999). That rule specifies those 

provisions of the CAA for which it is 

appropriate to treat tribes in a similar 

manner as states. Under the TAR, tribes 

may choose to develop and implement 

their own CAA programs, but are not 

required to do so. The TAR also 

establishes procedures and criteria by 

which tribes may request from the EPA 

a determination of eligibility for such 

treatment. The designations process 

contained in section 107(d) of the CAA 

is included among those provisions 

determined to be appropriate by the 

EPA for treatment of tribes in the same 

manner as states. Under the TAR, tribes 

generally are not subject to the same 

submission schedules imposed by the 

CAA on states. As authorized by the 

TAR, tribes may seek eligibility to 

submit designation recommendations to 

the EPA. In addition, CAA section 

301(d)(4) gives the EPA discretionary 

authority, in cases where it determines 

that treatment of tribes as identical to 

states is ‘‘inappropriate or 

administratively infeasible,’’ to provide 

for direct administration by regulation 

to achieve the appropriate purpose. 

Designation recommendations and 

supporting documentation for the NO2

NAAQS were submitted by most states 

and a few tribes to the EPA by January 

22, 2011. After receiving 

recommendations from states and tribes, 

and after reviewing and evaluating each 

recommendation, the EPA provided a 

response to the states and tribes on June 

29, 2011. In these letter responses, we 

indicated whether the EPA intended to 

make modifications to the initial state or 

tribal recommendations and explained 

the EPA’s reasons for making any such 

modifications. The EPA requested that 

states and tribes respond to any 

proposed EPA modifications by August 

29, 2011. We received comments from 

some states suggesting changes to the 

EPA’s proposed modifications and 

providing additional information. The 

EPA evaluated these comments, and, as 

a result, some of the final designations 

reflect further modifications to the 

initial state and tribal recommendations. 

The state and tribal letters, including 

the initial recommendations, the EPA’s 

June 2011 responses to those letters, 

including any modifications, and the 

subsequent state and tribal comment 

letters are in the docket for this action. 

Although not required by section 

107(d) of the CAA, the EPA also 

provided an opportunity for members of 

the public to comment on the EPA’s 

June 2011 response letters. In order to 

gather additional information for the 

EPA to consider before making final 

designations, EPA published a notice on 

July 7, 2011, (76 FR 39798) which 

invited the public to comment on the 

EPA’s intended designations. In that 

notice, the EPA provided the 

opportunity to all interested parties 

other than states and tribes to submit 

comments by August 8, 2011. State and 

tribal initial recommendations and 

EPA’s responses, including 

modifications, were posted on a 

publically accessible Web site (http:// 

www.epa.gov/airquality/nitrogenoxides/ 

designations/index.html). Comments 

from the public and EPA’s responses to 

comments are in the docket for this 

action. 

VI. What guidance did the EPA issue 

and how did the EPA apply the 

statutory requirements and applicable 

guidance to determine area 

designations and boundaries? 

In the notice of proposed rulemaking 

for the revised NO2 NAAQS (73 FR 

29184), the EPA issued proposed 

guidance, on its approach to 

implementing the standard, including 

its approach to initial area designations. 

The EPA solicited comment on that 

guidance and, in the notice of final 

rulemaking (75 FR 6475), adopted 

guidance concerning how to designate 

areas for the NO2 NAAQS. In that 

guidance the EPA recommended that 

monitoring data using the 3 most recent 

years of quality-assured air quality data 

from the current monitoring network, 

which would be for the years 2008– 

2010, be used to identify violations of 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 77, No. 33 / Friday, February 17, 2012 / Rules and Regulations 9535 

2The concept of ‘‘baseline areas’’ and their 

relationship to the area designations is described in 

40 CFR 81.300(b). The definition of baseline area 

appears in PSD regulations at 40 CFR 

52.21(b)(15)(i). 

the NO2 NAAQS. The EPA is basing 

these final designations on monitored 

NO2 concentrations from Federal 

Reference Method (FRM) monitors from 

calendar years 2008–2010. 

In the guidance, the EPA stated that 

in the event that a current NO2 monitor 

indicates a violation of the revised 

standards, the EPA intends to designate 

such areas ‘‘nonattainment’’ no later 

than 2 years following promulgation of 

the revised standards. The EPA also 

stated that it intends to designate the 

rest of the country as ‘‘unclassifiable’’ 

for the revised NO2 NAAQS until 

sufficient air quality data is collected 

from a near-roadway monitoring 

network. Once the near-roadway 

network is fully deployed and 3 years of 

air quality data are available, the EPA 

has authority under the CAA to 

redesignate areas as appropriate from 

‘‘unclassifiable’’ to ‘‘attainment’’ or 

‘‘nonattainment.’’ The EPA anticipates 

that sufficient data to conduct 

redesignations would be available after 

2015. 

In the EPA’s June 2011 response 

letters to state and tribal 

recommendations, the EPA stated that 

in response to recommendations and 

review of the 2008–2010 monitored NO2

concentrations, it intended to designate 

all areas of the U.S. as ‘‘unclassifiable/ 

attainment.’’ The EPA uses this 

designation in practice for initial 

designations to mean that available 

information does not indicate that the 

air quality in these areas exceeds the 

2010 NO2 NAAQS. 

VII. Comments 

In the EPA’s June 2011 response 

letters to state and tribal 

recommendations, the EPA 

recommended that states and tribes 

consider implications for the prevention 

of significant deterioration of air quality 

(PSD) program when proposing their 

boundaries. Several states responded by 

providing suggested changes to their 

recommended boundaries. The EPA has 

accepted these changes and has applied 

them in these final designations. 

The EPA received comments from one 

state and one trade association, both 

indicating that the EPA should 

designate areas as ‘‘attainment’’ rather 

than ‘‘unclassifiable/attainment.’’ 

The trade association commenter 

stated that a designation of ‘‘attainment’’ 

signifies the air is healthy while a 

designation of ‘‘unclassifiable’’ does not. 

The commenter acknowledges the 

concern that the current monitoring 

network is inadequate in many 

instances to determine if an area meets 

the 2010 NO2 NAAQS. Nonetheless, the 

commenter believes a designation of 

‘‘attainment’’ is appropriate where 

current monitoring shows no violations. 

The commenter acknowledges that 

redesignation to ‘‘nonattainment’’ 

would be appropriate if new monitors 

show violations of the 2010 NO2

NAAQS. 

The second comment, from a state, 

restated their recommendation that their 

entire state should be designated as 

‘‘attainment.’’ In their comment, they 

provide 2007–2010 data from seven NO2

monitors operated in the state. The 

commenter points out that no single 

year 98th percentile has exceeded 44 

percent of the 2010 NO2 NAAQS and 

design values have not exceeded 42 

percent of the 2010 NO2 NAAQS. 

After considering state and public 

comments on the EPA’s June 2011 

response letters to state and tribal 

recommendations, the EPA is finalizing 

designations for all areas of the U.S. as 

‘‘unclassifiable/attainment.’’ This 

designation is intended to indicate that 

for the purposes of initial area 

designations, available information does 

not indicate that air quality in these 

areas exceeds the NAAQS. 

Although all existing communitybased monitoring sites indicate 

attainment with the NO2 NAAQS, the 

existing NO2 monitoring network does 

not fully portray or represent the NO2

concentrations near roadways. Until 

more complete information on NAAQS 

compliance is available, the EPA does 

not believe a designation of 

‘‘attainment’’ is appropriate. 

VIII. Implications of Designations for 

Compliance With PSD Increments for 

NO2

The CAA’s PSD requirements are 

designed to ensure that economic 

growth will occur in a manner 

consistent with preserving clean air in 

areas not currently violating the NAAQS 

(see CAA sections 160–169). In such 

areas, new or modified major sources of 

NO2 must comply with maximum 

allowable increases (increments) in 

concentrations of NO2. In some parts of 

the U.S., ‘‘baseline areas’’ have already 

been established for NO2 increment 

analysis under the designations 

associated with the existing NO2 annual 

NAAQS.2 The boundaries for such areas 

are not affected by the newly designated 

areas listed as ‘‘unclassifiable/ 

attainment’’ for the 1-hour NO2 NAAQS. 

In addition, any increment baseline 

areas created in the future for the annual 

NO2 standard should be based on the 

existing designations that are associated 

with (and continue to apply to) the NO2

annual NAAQS. 

IX. What air quality data has the EPA 

used? 

The final NO2 designations contained 

in this action are based upon air quality 

monitoring data from calendar years 

2008–2010. 

X. How do designations affect Indian 

country? 

All counties, partial counties or Air 

Quality Control Regions listed in the 

table at the end of this document are 

designated as indicated. There are no 

areas of Indian country being designated 

nonattainment at this time. 

XI. Where can I find information 

forming the basis for this rule and 

exchanges between the EPA, states, and 

tribes related to this rule? 

Information providing the basis for 

this action and related decisions are 

provided in the docket for this 

rulemaking. The applicable EPA 

guidance memoranda, and copies of 

correspondence regarding this process 

between the EPA and the states, tribes, 

and other parties are available for 

review at the EPA Docket Center listed 

above in the addresses section of this 

document and on our designation Web 

site at http://www.epa.gov/airquality/ 

nitrogenoxides/designations/index.html. 

State-specific information is available 

from the EPA Regional Offices. 

XII. Statutory and Executive Order 

Reviews 

Upon promulgation of a new or 

revised NAAQS, the CAA requires the 

EPA to designate areas as attaining or 

not attaining the NAAQS. The CAA 

then specifies requirements for areas 

based on whether such areas are 

attaining or not attaining the NAAQS. In 

this final rule, the EPA assigns 

designations to areas as required. 

A. Executive Order 12866: Regulatory 

Planning and Review and Executive 

Order 13563: Improving Regulation and 

Regulatory Review 

This action will respond to the 

requirement to promulgate air quality 

designations after promulgation of a 

NAAQS. This type of action is exempt 

from review under Executive Orders 

12866 (58 FR 51735, October 4, 1993) 

and 13563 (76 FR 3821, January 21, 

2011). 

B. Paperwork Reduction Act 

This action does not impose an 

information collection burden under the 

provisions of the Paperwork Reduction 

mstockstill on DSK4VPTVN1PROD with RULES

9536 Federal Register / Vol. 77, No. 33 / Friday, February 17, 2012 / Rules and Regulations 

Act, 44 U.S.C. 3501 et seq. Burden is 

defined at 5 CFR 1320.3(b). This rule 

responds to the requirement to 

promulgate air quality designations after 

promulgation of a new or revised 

NAAQS. This requirement is prescribed 

in the CAA section 107. The present 

final rule does not establish any new 

information collection requirements. 

C. Regulatory Flexibility Act 

This final rule is not subject to the 

Regulatory Flexibility Act (RFA), which 

generally requires an agency to prepare 

a regulatory flexibility analysis for any 

rule that will have a significant 

economic impact on a substantial 

number of small entities. The RFA 

applies only to rules subject to noticeand-comment rulemaking requirements 

under the Administrative Procedure Act 

(APA) or any other statute. This rule is 

not subject to notice-and-comment 

requirements under the APA or any 

other statute because the rule is subject 

to CAA section 107(d)(2)(B), which does 

not require that the agency issue a 

notice of proposed rulemaking before 

issuing this rule. 

D. Unfunded Mandates Reform Act 

This action contains no federal 

mandate under the provisions of Title II 

of the Unfunded Mandates Reform Act 

of 1995 (UMRA), 2 U.S.C. 1531–1538 for 

state, local, or tribal governments or the 

private sector. The action imposes no 

enforceable duty on any state, local or 

tribal governments or the private sector. 

Therefore, this action is not subject to 

the requirements of sections 202 and 

205 of the UMRA. 

This action is also not subject to the 

requirements of section 203 of UMRA 

because it contains no regulatory 

requirements that might significantly or 

uniquely affect small governments. It 

does not create any additional 

requirements beyond those of the CAA 

and NO2 NAAQS (40 CFR 50.11). The 

CAA establishes the process whereby 

states take primary responsibility in 

developing plans to meet the NO2

NAAQS. 

E. Executive Order 13132: Federalism 

This final rule does not have 

federalism implications. 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. The CAA 

establishes the process whereby states 

take primary responsibility in 

developing plans to meet the NO2

NAAQS. This rule will not modify the 

relationship of the states and the EPA 

for purposes of developing programs to 

implement the NO2 NAAQS. Thus, 

Executive Order 13132 does not apply 

to this rule. 

F. Executive Order 13175: Consultation 

and Coordination With Indian Tribal 

Governments 

This action does not have tribal 

implications, as specified in Executive 

Order 13175 (65 FR 67249, November 9, 

2000). This rule concerns the 

designation of areas for the 1-hour NO2

NAAQS. The CAA provides for states 

and eligible tribes to develop plans to 

regulate emissions of air pollutants 

within their areas, as necessary, based 

on the designations. The TAR provides 

tribes the opportunity to apply for 

eligibility to develop and implement 

CAA programs such as programs to 

attain and maintain the NO2 NAAQS, 

but it leaves to the discretion of the tribe 

the decision of whether to apply to 

develop these programs and which 

programs, or appropriate elements of a 

program, the tribe will seek to adopt. 

This rule does not have a substantial 

direct effect on one or more Indian 

tribes. It does not create any additional 

requirements beyond those of the NO2

NAAQS (40 CFR section 50.11). This 

rule establishes the designation for 

certain areas of the country for the NO2

NAAQS but no areas in Indian country 

are being designated nonattainment 

under this rule. Consequently, no tribe 

has any immediate requirement to 

implement a CAA program to attain the 

1-hour NO2 NAAQS in Indian Country 

at this time. Furthermore, this rule does 

not affect the relationship or 

distribution of power and 

responsibilities between the federal 

government and Indian tribes. The CAA 

and the TAR establish the relationship 

of the federal government and tribes in 

developing plans to attain the NAAQS, 

and this rule does nothing to modify 

that relationship. Thus, Executive Order 

13175 does not apply to this action. 

Although Executive Order 13175 does 

not apply to this action, the EPA 

communicated with tribal leaders and 

environmental staff regarding the 

designations process. The EPA also sent 

individualized letters to all federally 

recognized tribes to explain the 

designation process for the 2010 NO2

NAAQS, to provide the EPA 

designations guidance, and to offer 

consultation with the EPA. The EPA 

provided further information to tribes 

through presentations at the National 

Tribal Forum and through participation 

in National Tribal Air Association 

conference calls. The EPA also sent 

individualized letters to all federally 

recognized tribes that submitted 

recommendations to the EPA about the 

EPA’s intended designations for the NO2

standards and offered tribal leaders the 

opportunity for consultation. These 

communications provided opportunities 

for tribes to voice concerns to the EPA 

about the general designations process 

for the NO2 NAAQS, as well as concerns 

specific to a tribe, and informed the EPA 

about key tribal concerns regarding 

designations as the rule was under 

development. 

G. Executive Order 13045: Protection of 

Children From Environmental Health 

and Safety Risks 

The EPA interprets Executive Order 

13045 (62 FR 19885, April 23, 1997) as 

applying only to those regulatory 

actions that concern health or safety 

risks, such that the analysis required 

under section 5–501 of the Executive 

Order has the potential to influence the 

regulation. This action is not subject to 

Executive Order 13045 because it does 

not establish an environmental standard 

intended to mitigate health or safety 

risks. 

H. Executive Order 13211: Actions That 

Significantly Affect Energy Supply, 

Distribution, or Use 

This action is not subject to Executive 

Order 13211 (66 FR 28355 (May 22, 

2001)), because it is not a significant 

regulatory action under Executive Order 

12866. 

I. National Technology Transfer and 

Advancement Act (NTTAA) 

Section 12(d) of the NTTAA of 1995, 

Public Law 104–113, section 12(d) (15 

U.S.C. 272 note) directs the EPA to use 

voluntary consensus standards (VCS) in 

its regulatory activities unless to do so 

would be inconsistent with applicable 

law or otherwise impracticable. 

Voluntary consensus standards are 

technical standards (e.g., materials 

specifications, test methods, sampling 

procedures, and business practices) that 

are developed or adopted by VCS 

bodies. The NTTAA directs the EPA to 

provide Congress, through OMB, 

explanations when the Agency decides 

not to use available and applicable VCS. 

This action does not involve technical 

standards. Therefore, the EPA did not 

consider the use of any VCS. 

J. Executive Order 12898: Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations 

Executive Order 12898 (59 FR 7629 

(Feb. 16, 1994)) establishes federal 

executive policy on environmental 

justice. Its main provision directs 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 77, No. 33 / Friday, February 17, 2012 / Rules and Regulations 9537 

federal agencies, to the greatest extent 

practicable and permitted by law, to 

make environmental justice part of their 

mission by identifying and addressing, 

as appropriate, disproportionately high 

and adverse human health or 

environmental effects of their programs, 

policies, and activities on minority 

populations and low-income 

populations in the U.S. 

The CAA requires that the EPA 

designate as nonattainment ‘‘any area 

that does not meet (or that contributes 

to ambient air quality in a nearby area 

that does not meet) the national primary 

or secondary ambient air quality 

standard for the pollutant.’’ By 

designating as nonattainment all areas 

where available information indicates a 

violation of the NO2 NAAQS, this action 

protects all those residing, working, 

attending school, or otherwise present 

in those areas regardless of minority or 

economic status. 

EPA has determined that this final 

rule will not have disproportionately 

high and adverse human health or 

environmental effects on minority or 

low-income populations because it 

increases the level of environmental 

protection for all affected populations 

without having any disproportionately 

high and adverse human health or 

environmental effects on any 

population, including any minority or 

low-income population 

K. Congressional Review Act 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the U.S. The EPA will 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 U.S. prior to 

publication of the rule in the Federal 

Register. A major rule cannot take effect 

until 60 days after it is published in the 

Federal Register. This action is not a 

‘‘major rule’’ as defined by 5 U.S.C. 

804(2). This rule will be effective 

February 29, 2012. 

L. Judicial Review 

Section 307(b)(1) of the CAA indicates 

which Federal Courts of Appeal have 

venue for petitions of review of final 

actions by EPA. This section provides, 

in part, that petitions for review must be 

filed in the Court of Appeals for the 

District of Columbia Circuit: (i) When 

the agency action consists of ‘‘nationally 

applicable regulations promulgated, or 

final actions taken, by the 

Administrator,’’ or (ii) when such action 

is locally or regionally applicable, if 

‘‘such action is based on a 

determination of nationwide scope or 

effect and if in taking such action the 

Administrator finds and publishes that 

such action is based on such a 

determination.’’ 

This rule designating areas for the 

2010 NO2 NAAQS is ‘‘nationally 

applicable’’ within the meaning of 

section 307(b)(1). This rule establishes 

designations for areas across the U.S. for 

the 2010 NO2 NAAQS. At the core of 

this rulemaking is EPA’s interpretation 

of the definition of nonattainment under 

section 107(d)(1) of the CAA, and its 

application of that interpretation to 

areas across the country. 

For the same reasons, the 

Administrator also is determining that 

the final designations are of nationwide 

scope and effect for the purposes of 

section 307(b)(1). This is particularly 

appropriate because, in the report on the 

1977 Amendments that revised section 

307(b)(1) of the CAA, Congress noted 

that the Administrator’s determination 

that an action is of ‘‘nationwide scope 

or effect’’ would be appropriate for any 

action that has a scope or effect beyond 

a single judicial circuit. H.R. Rep. No. 

95–294 at 323, 324, reprinted in 1977 

U.S.C.C.A.N. 1402–03. Here, the scope 

and effect of this rulemaking extends to 

numerous judicial circuits since the 

designations apply to areas across the 

country. In these circumstances, section 

307(b)(1) and its legislative history calls 

for the Administrator to find the rule to 

be of ‘‘nationwide scope or effect’’ and 

for venue to be in the D.C. Circuit. 

Thus, any petitions for review of final 

designations must be filed in the Court 

of Appeals for the District of Columbia 

Circuit within 60 days from the date 

final action is published in the Federal 

Register.

FOR FURTHER INFORMATION CONTACT:

SUPPLEMENTARY INFORMATION: NMFS 

manages the groundfish fishery in the 

GOA exclusive economic zone 

according to the Fishery Management 

Plan for Groundfish of the Gulf of 

Alaska (FMP) prepared by the North 

Pacific Fishery Management Council 

under authority of the MagnusonStevens Fishery Conservation and 

Management Act. Regulations governing 

fishing by U.S. vessels in accordance 

with the FMP appear at subpart H of 

50 CFR part 600 and 50 CFR part 679. 

NMFS closed directed fishing for 

pollock in Statistical Area 630 of the 

GOA under § 679.20(d)(1)(iii) on 

January 23, 2012 (77 FR 3638, January 

25, 2012). 

As of February 10, 2012, NMFS has 

determined that approximately 5,298 

metric tons of pollock remain in the 

directed fishing allowance for pollock in 

Statistical Area 630 of the GOA. 

Therefore, in accordance with 

§ 679.25(a)(1)(i), (a)(2)(i)(C), and 

(a)(2)(iii)(D), and to fully utilize the A 

season allowance of the 2012 TAC of 

pollock in Statistical Area 630 of the 

GOA, NMFS is terminating the previous 

closure and is reopening directed 

fishing pollock in Statistical Area 630 of 

the GOA. The Administrator, Alaska 

Region (Regional Administrator) 

considered the following factors in 

reaching this decision: (1) the current 

catch of pollock in Statistical Area 630 

of the GOA and, (2) the harvest capacity 

and stated intent on future harvesting 

patterns of vessels in participating in 

this fishery. 

Classification 

This action responds to the best 

available information recently obtained 

from the fishery. The Assistant 

Administrator for Fisheries, NOAA 

(AA), finds good cause to waive the 

requirement to provide prior notice and 

opportunity for public comment 

pursuant to the authority set forth at 5 

U.S.C. 553(b)(B) as such requirement is 

impracticable and contrary to the public 

interest. This requirement is 

impracticable and contrary to the public 

interest as it would prevent NMFS from 

responding to the most recent fisheries 

data in a timely fashion and would 

delay the opening of the pollock fishery
