Air Quality Designations for the 2008 Lead (Pb) National Ambient 
Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes air quality designations for most areas 
in the United States for the 2008 lead (Pb) National Ambient Air 
Quality Standards (NAAQS). In a previous action established on November 
16, 2010, the EPA designated as ``nonattainment'' 16 areas as violating 
the 2008 Pb NAAQS based on data from the pre-2010 monitoring network. 
For all other areas, the EPA deferred action so that data from newly 
deployed monitors could be considered in making appropriate designation 
decisions. In this action, the EPA is designating all remaining areas 
of the United States, including Indian country. The Clean Air Act (CAA) 
requires areas designated nonattainment by this rule to undertake 
certain planning and pollution control activities to attain the 
standards as quickly as reasonably possible.

DATES: Effective Date: The effective date of this rule is December 31, 
2011.

II. What is the purpose of this document?

    The purpose of this action is to promulgate and announce 
designations and boundaries for areas of the country for the 2008 Pb 
NAAQS based on available information, in accordance with the 
requirements of the CAA. All area designations for each state, and the 
boundaries for each area, appear in the table at the end of this final 
rule. The EPA has been working closely with the states involved in 
these designations and has taken several steps to announce that this 
rule is available. The EPA has posted the notice on the EPA's 
designations Web site and provided a copy of the rule to those states 
with nonattainment areas.
    This notice identifies the five areas being designated as 
nonattainment areas for the 2008 Pb NAAQS. These five areas surround 
violating monitors in Arecibo, Puerto Rico; Chicago, Illinois; Belding, 
Michigan; Saline, Kansas; and Pottawattamie, Iowa. The basis for 
designating these areas as nonattainment areas is monitored air quality 
data from calendar years 2008-2010 indicating violations of the NAAQS. 
For these areas being designated nonattainment, states must develop a 
State Implementation Plan (SIP) that meets the requirements of section 
172(c) and subpart 5 of Part D of the CAA, including providing for 
attainment of the NAAQS as expeditiously as practicable, but no later 
than December 31, 2016. These SIPs must be submitted to the EPA within 
18 months of the effective date of these designations, i.e., by June 
30, 2013.\1\
---------------------------------------------------------------------------

    \1\ In addition, as discussed in the proposed and final Pb NAAQS 
rules, all states are required to submit SIPs pursuant to section 
110(a)(1) (``infrastructure SIPs'') within 3 years of promulgation 
of the new standard.
---------------------------------------------------------------------------

    This notice also identifies the expansion of the boundary of one 
nonattainment area--the Lower Beaver Valley nonattainment area in 
Pennsylvania--that was designated nonattainment on November 16, 2010. 
The expansion incorporates additional land area that the EPA has 
determined does not meet the 2008 Pb NAAQS. This action does not affect 
the required attainment date or SIP submission deadline for this 
nonattainment area.
    The EPA is designating three areas (Knox County, Tennessee; an area

[[Page 72099]]

surrounding Hayden, Arizona; and Orange County, New York) as 
unclassifiable on the basis that there are available monitoring data 
from recent periods indicating a significant likelihood that the areas 
may be violating the 2008 Pb NAAQS, but the available information is 
insufficient at this time to make nonattainment designations. In the 
2008 Pb NAAQS rule, the EPA required new monitors to be sited near 
sources emitting more than one ton per year or more beginning in 2010 
and in certain non-source oriented locations by December 27, 2011.\2\ 
Due to the timing of monitor siting, monitoring data are available for 
the first several months of 2011 for some sites with no 2008-2010 data, 
two of which have data in AQS that exceed the standard (Knox County, 
Tennessee and Hayden, Arizona). A previously established monitor in the 
Orange County, New York, area also has data in AQS from early 2011 that 
exceed the standard. Because of the form of the 2008 Pb NAAQS, one 3-
month average ambient air concentration over 0.15 micorgrams per cubic 
meter ([mu]g/m\3\) is enough to cause a violation of the Pb NAAQS. 
However, before the EPA can finalize nonattainment designation for 
these areas, the data that were reported to AQS must be quality assured 
and certified and appropriate nonattainment area boundaries must be 
defined for the areas. Therefore, the EPA is designating these three 
areas as unclassifiable until this process can be completed.
---------------------------------------------------------------------------

    \2\ EPA subsequently revised these requirements, including by 
lowering the emission threshold for source-oriented monitoring to 
0.5 tpy. See 75 FR 81127 (Dec. 27, 2010).
---------------------------------------------------------------------------

    The EPA received a recommendation on behalf of the Governor of 
Arizona with recommended boundaries for an area surrounding Hayden, 
Arizona, and the EPA is designating that area as unclassifiable 
consistent with that recommendation. Consistent with the EPA's view 
that the perimeter of a county containing a violating monitor is the 
initial presumptive boundary for nonattainment areas, the EPA is 
designating the entirety of Orange County, New York, and Knox County, 
Tennessee, as unclassifiable. However, the EPA recognizes that 
experience with other initial designations for the Pb NAAQS has 
indicated that where a NAAQS violation is attributable to a single 
source, area-specific analyses have served as a basis for designating a 
nonattainment area that is smaller than the county. Accordingly, before 
redesignating these two areas as nonattainment and consistent with the 
CAA, the EPA intends to work with the states to identify specific 
boundaries that appropriately encompass violating areas and any areas 
contributing to violations in these counties. The boundaries of any 
nonattainment area may well be smaller than the county boundaries, and 
in such case the EPA anticipates that the remainder of these two 
counties would be redesignated unclassifiable/attainment. The EPA notes 
that, although it is designating these three areas as 
``unclassifiable'' to reflect the recent monitoring data, there are no 
additional planning or control requirements that apply as a result of 
an unclassifiable designation, as compared to a designation of 
``unclassifiable/attainment.''
    All other areas of the country are being designated as 
unclassifiable/attainment, meaning the available information does not 
indicate that the air quality in these areas exceeds the 2008 Pb NAAQS.
    When the EPA issued the 2008 Pb NAAQS, we provided that the 1978 Pb 
NAAQS would be revoked 1 year after the effective date of designations 
for the 2008 NAAQS, except in areas designated nonattainment for the 
1978 NAAQS where the standard will remain in effect until a SIP is 
approved for the new standard. There are two areas designated 
nonattainment for the 1978 NAAQS: Herculaneum, Missouri, and East 
Helena, Montana. Herculaneum was designated nonattainment for the 2008 
standard in 2010, and thus the 1978 standard will remain in effect 
until an attainment SIP for the 2008 NAAQS is approved by the EPA. East 
Helena is being designated unclassifiable/attainment for the 2008 
standard in this action, and the 1978 standard will remain in effect 
until a maintenance SIP for the 2008 NAAQS is approved by the EPA. For 
all other areas designated in this action, the 1978 standard is revoked 
as of December 31, 2012.
    In addition to making designations for the 2008 Pb NAAQS, the EPA 
is also revising 40 CFR part 81 to clarify the presentation of 
designations for the 1978 standard and the 2008 standard and to correct 
certain inadvertent errors concerning the 1978 standard. In making 
designations for the 2008 standard last year, the EPA inadvertently 
changed certain information in part 81 for the 1978 standard, such as 
identifying areas that had been designated ``unclassifiable'' as 
``attainment,'' identifying areas that were not designated at all as 
``unclassifiable,'' or including the wrong effective date for a 
designation.\3\ Although these errors have no practical effect, and the 
1978 standard will be revoked for all but two areas by December 31, 
2012, the EPA did not intend to alter any designations for the 1978 
standard in making designations for the 2008 standard and is thus 
correcting the errors to ensure that part 81 reflects the proper 
designations for the 1978 standard.
---------------------------------------------------------------------------

    \3\ No areas were inadvertently identified as ``nonattainment.''
---------------------------------------------------------------------------

III. What is lead?

    Lead (Pb) is a metal found naturally in the environment and present 
in some manufactured products. The major sources of Pb air emissions 
were historically motor vehicles (such as cars and trucks) and 
industrial sources. Motor vehicles emissions of Pb have been 
dramatically reduced with the phase-out of leaded gasoline, but Pb is 
still used as an additive in general aviation gasoline used in piston-
engine aircraft and remains a trace contaminant in other fuels. Large 
industrial sources of Pb emissions currently include metals processing, 
particularly primary and secondary Pb smelters. Lead is also emitted 
from sources such as: Iron and steel foundries; primary and secondary 
copper smelters; industrial, commercial, and institutional boilers; 
waste incinerators; glass manufacturing; and cement manufacturing.

IV. What are the health and welfare concerns addressed by the Pb 
standards?

    Lead is generally emitted in the form of particles, which can end 
up being deposited in water, soil, and dust. People may be exposed to 
Pb by inhaling it, or by ingesting lead-contaminated food, water, soil, 
or dust. Once in the body, Pb is quickly absorbed into the bloodstream 
and can result in a broad range of adverse health effects. These may 
include damage to the central nervous system, cardiovascular function, 
kidneys, immune system, and red blood cells. Children are particularly 
vulnerable to Pb exposure, in part because they are more likely to 
ingest Pb and in part because their still-developing bodies are more 
sensitive to the effects of Pb. The harmful effects to children's 
developing nervous systems (including their brains) arising from Pb 
exposure may include intelligence quotient (IQ) loss, poor academic 
achievement, long-term learning disabilities, and an increased risk of 
delinquent behavior.
    Lead is persistent in the environment and accumulates in soils and 
sediments through deposition from air sources, direct discharge of 
waste streams to water bodies, mining, and erosion. Ecosystems near 
some longstanding

[[Page 72100]]

point sources of Pb demonstrate a wide range of adverse effects 
including losses in biodiversity, changes in community composition, 
decreased growth and reproductive rates in plants and animals, and 
neurological effects in vertebrates.

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 Pb NAAQS on October 15, 
2008, which was published in the Federal Register on November 12, 2008, 
and became effective January 12, 2009. Based on the Administrator's 
review of the scientific evidence, including numerous studies published 
since the last review of the Pb NAAQS, and taking into consideration 
the comments expressed by the Clean Air Scientific Advisory Committee 
and the public, the Administrator revised the standard from a level of 
1.5 [mu]g/m\3\ to a level of 0.15 [micro]g/m\3\. In addition, the 
Administrator changed the averaging time and form to a maximum rolling 
3-month average evaluated over a 3-year period. The rule also 
established new requirements for Pb monitoring networks, including the 
requirement that new Pb monitors be located in close proximity to the 
largest Pb emissions sources by January 1, 2010.
    The process for designating areas following promulgation of a new 
or revised NAAQS is contained in section 107(d) of the CAA. The CAA 
requires the EPA to complete the initial area designation process 
within 2 years of promulgating a new or revised NAAQS. However, if 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. Tribes are not 
required to submit recommendations, but the EPA encourages their 
participation in the designations process. 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 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, as contemplated 
by section 107(d)(1)(B)(ii). 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, 
pursuant to section 107(d)(1)(B)(ii).
    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.\4\
---------------------------------------------------------------------------

    \4\ This view was confirmed in Catawba County v. EPA, 571 F.3d 
20 (D.C. Cir. 2009).
---------------------------------------------------------------------------

    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 non-contiguous 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 federally-recognized 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. 63 FR 
7254, codified at 40 CFR part 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.
    To date, one tribe has applied under the TAR for eligibility to 
submit its own recommendations under section 107(d). Nonetheless, the 
EPA invited all tribes to submit recommendations concerning 
designations for the 2008 Pb NAAQS. The EPA worked with the tribes that 
requested an opportunity to submit designation recommendations. Tribes 
were provided an opportunity to submit their own recommendations and 
supporting documentation and could also comment on state 
recommendations and the EPA modifications.
    In light of the new Pb monitoring network, the EPA planned to 
complete the initial area designations for Pb in two rounds. 
Designation recommendations and supporting documentation were 
previously submitted by most states and a few tribes to the EPA by 
October 15, 2009. In the first round, established on November 16, 2010, 
the EPA designated

[[Page 72101]]

as ``nonattainment'' 16 areas as violating the 2008 Pb NAAQS based on 
2007-2009 air quality data from the pre-2010 monitoring network. For 
all other areas, the EPA extended the deadline for designations by up 
to 1 year so that data from the newly deployed monitors can be 
considered in making appropriate designation decisions.
    For the second round of designations, states and tribes were given 
an opportunity to update their recommendation letters, for these 
remaining areas, by December 15, 2010. 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 15, 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 modifications, made by the EPA, by August 15, 2011. The state 
and tribal letters, including the initial recommendations, and 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, 
the EPA published a notice on June 21, 2011, (76 FR 36042) which 
invited the public to comment on the response letters the EPA sent to 
states in June 2011. In that notice, the EPA provided the opportunity 
to all interested parties other than states and tribes to submit 
comments by July 21, 2011. The state and tribal initial recommendations 
and the EPA's responses, including modifications, were posted on a 
publicly accessible Web site (https://www.epa.gov/leaddesignations/2008standards/). We did not receive any comments questioning 
our general approach to these designations. Comments from the public 
and the EPA's responses to state-specific comments are in the docket 
for this action.
    In this rule, the EPA is designating as ``nonattainment'' five 
areas violating the 2008 Pb NAAQS based on 2008-2010 air quality data 
from the newly deployed monitoring network, extending a previously 
designated nonattainment area to encompass a violating monitor sited 
under the newly deployed monitoring network, and designating three 
areas as unclassifiable based on data reported to AQS in early 2011 
that exceed the 2008 Pb NAAQS but have not been quality assured and 
certified. All other areas are designated 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 2008 Pb NAAQS.

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 Pb 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 (73 FR 66964), adopted guidance concerning 
how to determine the boundaries for nonattainment areas for the Pb 
NAAQS.\5\ In that guidance, the EPA indicated that it would use 
monitoring data from the 3 most recent calendar years to identify a 
violation of the Pb NAAQS. This is appropriate because the form of the 
Pb NAAQS is calculated over 36 consecutive valid 3-month site means 
(specifically for a 3 calendar year period and the 2 previous 
months).\6\ The EPA is generally basing these final designations on 
monitored Pb concentrations from Federal Reference Method (FRM) and 
Federal Equivalent Method (FEM) monitors from calendar years 2008-2010, 
which were the most recent quality assured and certified data available 
upon which to base designations decisions.\7\
---------------------------------------------------------------------------

    \5\ See also, ``Area Designations for the Revised Lead National 
Ambient Air Quality Standards,'' memorandum to Regional 
Administrators, Regions I-X, from William Harnett, dated August 21, 
2009.
    \6\ For convenience, this notice refers to the period of 3 
calendar years and the 2 previous months simply as 3 calendar years. 
Thus, monitoring for ``calendar years 2008-2010'' includes data from 
November 2007 through December 2010.
    \7\ As noted above, the three unclassifiable designations are 
based on uncertified 2011 monitoring data, but there are no planning 
or control requirements that apply as a result of an unclassifiable 
designation.
---------------------------------------------------------------------------

    In the guidance, the EPA stated that the perimeter of a county 
containing a violating monitor would be the initial presumptive 
boundary for nonattainment areas, but also stated that the state, 
tribe, and/or the EPA could conduct additional area-specific analyses 
that could justify establishing either a larger or smaller area. The 
EPA indicated that the following factors should be considered in an 
analysis of whether to exclude portions of a county and whether to 
include additional nearby areas outside the county as part of the 
designated nonattainment area: (1) Emissions in areas potentially 
included versus excluded from the nonattainment area; (2) Air quality 
in potentially included versus excluded areas; (3) Population density 
and degree of urbanization including commercial development in included 
versus excluded areas; (4) Expected growth (including extent, pattern, 
and rate of growth); (5) Meteorology (weather/transport patterns); (6) 
Geography/topography (mountain ranges or other air basin boundaries); 
(7) Jurisdictional boundaries (e.g., counties, air districts, 
reservations, etc.); and (8) Level of control of emission sources. The 
EPA further indicated that we would consider information provided by 
the state resulting from one or more of the following techniques: (1) 
Qualitative analysis; (2) spatial interpolation of air quality 
monitoring data; or (3) air quality simulation by dispersion modeling.
    The EPA received comments on the proposed guidance suggesting that 
violations of the Pb NAAQS were likely to occur in close proximity to 
stationary sources of Pb. In response, the EPA indicated that it agreed 
that Pb emissions do not generally transport over long distances (e.g., 
as compared to fine particulate matter), and that in situations where a 
single source, rather than multiple sources, is causing a NAAQS 
violation, the EPA believes that a state may well be able to use area-
specific analyses to determine whether a nonattainment area that is 
smaller than the county boundary is appropriate.
    The EPA found that states did use the factors and the variety of 
techniques identified by the EPA in making recommendations for 
nonattainment areas smaller than the county. In recommending 
boundaries, the EPA and states began with monitors that recorded a 
violation of the 2008 Pb NAAQS. As provided in Appendix R to 40 CFR 
part 50, all valid Pb-TSP data and all valid Pb-PM10 data 
measured by a FRM or FEM monitor submitted to the EPA's Air Quality 
System (AQS), or otherwise available to the EPA, and meeting the 
requirements of 40 CFR part 58, including Appendices A, C, and E, are 
used in design value calculations.\8\
---------------------------------------------------------------------------

    \8\ A design value is the air quality value that is compared to 
the NAAQS to determine compliance. For the Pb NAAQS, the design 
value is the highest 3-month site mean of daily Pb concentrations 
over 36 consecutive 3-month means for 3 calendar years.

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

[[Page 72102]]

    For areas with a violating monitor, the designated nonattainment 
area must encompass the entire area that does not meet, and any nearby 
area that contributes to ambient air quality in the area that does not 
meet, the 2008 Pb NAAQS. Given the sources and characteristics of Pb 
emissions, states and the EPA generally found factors such as 
emissions, air quality, and meteorology to be particularly relevant in 
determining appropriate boundaries, while factors such as population 
density and expected growth were not as relevant for the 2008 Pb NAAQS, 
and thus did not play a significant role in determining boundaries. In 
some cases, states made a judgment that it was important to follow 
jurisdictional boundaries, particularly where jurisdictional boundaries 
smaller than a county exist. In other cases, states chose to rely 
primarily on air dispersion modeling to determine the recommended 
boundaries for nonattainment areas. In each case, the EPA reviewed the 
state recommendations and, for the most part, the EPA has accepted the 
state's recommendations; however, where the EPA felt that changes were 
necessary to a state's initial recommendation, we conveyed those issues 
to the state and have worked with the state to revise the boundaries.

VII. What air quality data has the EPA used?

    The final Pb designations contained in this action are generally 
based upon air quality monitoring data from calendar years 2008-2010. 
As discussed previously, the form of the standard requires comparison 
of monitoring values from up to 36 3-month rolling averages (i.e., 3 
years, plus 2 preceding months). A violation will have occurred if any 
of the 36 3-month average concentrations of either Pb-TSP or Pb-
PM10 exceeds the level of the NAAQS, and a finding of 
compliance will require that all 36 3-month averages of Pb-TSP be at or 
below the level of the NAAQS.\9\ Moreover, pursuant to the CAA, the EPA 
is making designations as expeditiously as practicable. Section 107(d) 
requires the EPA to designate areas as nonattainment if sufficient data 
exist to support such a designation.
---------------------------------------------------------------------------

    \9\ For additional details on how to determine when the 2008 Pb 
NAAQS have been met, see 40 CFR part 50, Appendix R.
---------------------------------------------------------------------------

    Due to the timing of the siting of monitors under the monitoring 
plan established in the 2008 Pb NAAQS rule, data are available for 
several sites for early 2011 that did not have data available for 2008-
2010. Two such monitors, one in Hayden, Arizona and one in Knox County, 
Tennessee, have data in AQS that exceed the standard for at least one 
3-month period in 2011. Additionally, a site in Orange County, New York 
also has monitoring data in AQS for early 2011 that exceed the 
standard. The EPA anticipates that these data will be sufficient to 
support nonattainment designations or other appropriate action once 
quality assured and certified. However, the EPA cannot finalize 
nonattainment designations for these areas at this time because the 
data that were reported to AQS have not yet been quality assured and 
certified and appropriate nonattainment area boundaries have not been 
defined for two of the areas. Therefore, the EPA is designating these 
three areas as unclassifiable until this process can be completed.\10\ 
As noted above, there are no additional planning or control 
requirements that apply as a result of an unclassifiable designation, 
as compared to a designation of ``unclassifiable/attainment.''
---------------------------------------------------------------------------

    \10\ The monitors that have shown apparent violations are the 
following: AQS ID 04-007-1002 in Hayden, AZ; AQS ID 47-093-0023 in 
Knox Co., TN; and AQS ID 36-071-3002 in Orange Co., NY.
---------------------------------------------------------------------------

VIII. 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. For the first round of Pb designations, the EPA only 
designated nonattainment areas and deferred all remaining areas to this 
second round of Pb designations. All areas in Indian country are being 
designated unclassifiable/attainment.

IX. 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 is provided in the technical support documents (TSDs), 
response to comments document, and other information in the docket. The 
TSDs, applicable EPA guidance memoranda, copies of correspondence 
regarding this process between the EPA and the states, tribes, and 
other parties, and the EPA's responses to comments, 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 https://www.epa.gov/leaddesignations/2008standards/. State-specific information 
is available from the EPA Regional Offices.

X. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action will establish nonattainment designations for certain 
areas of the country for the Pb NAAQS. This action is not a 
``significant regulatory action'' under the terms of Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011) and is therefore not subject to review under those orders.

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
Burden is defined at 5 CFR 1320.3(b). This rule will respond to the 
requirement to promulgate air quality designations after promulgation 
of a NAAQS. This requirement is prescribed in the CAA section 107 of 
title 1.

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 notice-and-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 not subject to the APA and 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

[[Page 72103]]

does not create any additional requirements beyond those of the CAA and 
Pb NAAQS (40 CFR 50.16); therefore, no UMRA analysis is needed. This 
rule establishes nonattainment designations for certain areas of the 
country for the Pb NAAQS. The CAA requires states to develop plans, 
including control measures, based on the designations for areas within 
the state.
    One mandate that may apply as a consequence of this action to all 
designated nonattainment areas is the requirement under CAA section 
176(c) and associated regulations to demonstrate general conformity of 
federal actions to SIPs. These rules apply to federal agencies making 
conformity determinations. The EPA concludes that such conformity 
determinations will not cost $100 million or more in the aggregate.
    The EPA believes that any new controls imposed as a result of this 
action will not cost in the aggregate $100 million or more annually. 
Thus, this federal action will not impose mandates that will require 
expenditures of $100 million or more in the aggregate in any 1 year.
    Nonetheless, the EPA communicated with government entities affected 
by this rule, including states, tribal governments, and local air 
pollution control agencies.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires the EPA to develop an accountable process to ensure 
meaningful and timely input by state and local officials in the 
development of regulatory policies that have federalism implications. 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the states, or the relationship between the national 
government and the states, or on the distribution of power and 
responsibilities among the various levels of government.''
    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 Pb NAAQS. This rule will not modify the relationship of the states 
and the EPA for purposes of developing programs to implement the Pb 
NAAQS. Thus, Executive Order 13132 does not apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action is not designating any tribal areas as nonattainment. 
Executive Order 13175, entitled ``Consultation and Coordination with 
Indian Tribal Governments'' (65 FR 67249, November 2, 2000), requires 
the EPA to develop an accountable process to ensure ``meaningful and 
timely input by tribal officials in the development of regulatory 
policies that have Tribal implications.'' 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 Pb NAAQS. The CAA provides for states and eligible tribes to 
develop plans to regulate emissions of air pollutants within their 
areas based on their 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 Pb NAAQS, but it 
leaves to the discretion of the tribe the decision of whether to 
develop and implement 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 Pb NAAQS (40 CFR 
50.16). This rule establishes the designation for most areas of the 
country for the Pb NAAQS but no areas in Indian country are being 
designated as nonattainment under this rule. Additionally, no tribe has 
implemented a CAA program to attain the Pb NAAQS 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. Because this rule does 
not have tribal implications, Executive Order 13175 does not apply.
    Although Executive Order 13175 does not apply to this rule, 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 
2008 Pb 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 Pb 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 Pb 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 action is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it is not economically significant as defined 
in Executive Order 12866. However, the protection offered by the Pb 
NAAQS may be especially important for children because neurological 
effects in children are among if not the most sensitive health 
endpoints for Pb exposure. Because children are considered a sensitive 
population, in setting the Pb NAAQS we carefully evaluated the 
environmental health effects of exposure to Pb pollution among 
children. These effects and the size of the population affected are 
summarized in the EPA's 2006 Air Quality Criteria Document for Pb and 
in the proposed and final Pb NAAQS rules. See https://www.epa.gov/airquality/lead/fr/20081112.pdf.

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

[[Page 72104]]

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 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 EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on any population, including minority or low-income 
populations.

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 December 31, 2011.

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 the 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 2008 Pb NAAQS is ``nationally 
applicable'' within the meaning of section 307(b)(1). This rule 
establishes designations for areas across the U.S. for the 2008 Pb 
NAAQS. At the core of this rulemaking is the 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.
