Particulate matter with an aerodynamic diameter less than or equal to a nominal ten micrometers, or PM10, is one of these ambient air pollutants for which EPA has established health-based standards. EPA revised the NAAQS for particulate matter on July 1, 1987 (52 FR 24633), replacing standards for total E:\FR\FM\19MRR1.SGM 19MRR1 Federal Register / Vol. 78, No. 53 / Tuesday, March 19, 2013 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES suspended particulates (TSP less than 30 microns in diameter) that were set in 1971 with new standards applying only to particulate matter up to 10 microns in diameter (PM10). Simultaneously, EPA published revised requirements for state implementation plans (SIPs) to attain and maintain the standards (52 FR 24672, July 1, 1987). To focus Federal and State resources on implementing the PM10 NAAQS first in those areas of the country believed to be violating the standards, EPA classified all areas of the Nation into one of three groups. Group I areas were those having a very high probability of violating the PM10 standards based on ambient air quality data available for 1984 through 1987 for PM10 and TSP. Group II areas had a moderate probability of violating the standards, and Group III areas were those believed to be currently attaining the standards. A list of Group I and II areas in each State was published on August 7, 1987 (52 FR 29383). Within Imperial County,1 EPA listed two areas, ‘‘Imperial Valley planning area’’ and ‘‘Yuma planning area,’’ 2 among the Group I areas. The remaining portions of any State not listed as Group I or II were classified in Group III. On October 31, 1990 (55 FR 45799), EPA clarified the descriptions of several Group I and II areas of concern. In so doing, EPA did not clarify the description of the ‘‘Imperial Valley planning area’’ but did eliminate ‘‘Yuma planning area’’ as a Group I or II area of concern within Imperial County, California. Under section 107(d)(4)(B) of the Clean Air Act (CAA or ‘‘Act’’), as amended in 1990, certain areas were designated as nonattainment for PM10 by operation of law upon enactment of the 1990 Amendments (i.e., November 15, 1990). These areas included all areas included in Group I in EPA’s 1987 list (unless changed by EPA prior to the 1990 Amended Act) as well as certain Group II and III areas. The Imperial Valley planning area, as a former ‘‘Group I’’ area, was one of the areas designated as a PM10 nonattainment area by operation of law effective November 15, 1990. On March 15, 1991 (56 FR 11101), EPA announced all of those areas that were designated nonattainment for PM10 by operation of law and announced that all of the nonattainment areas were 1 Imperial County is located in the southeastern corner of California. It borders Mexico to the south, Riverside County to the north, Arizona to the east, and San Diego County to the west. Imperial County lies within the Sonoran Desert. 2 EPA also listed ‘‘Yuma planning area’’ as a Group I area within Yuma County, Arizona. VerDate Mar<15>2010 16:13 Mar 18, 2013 Jkt 229001 classified as ‘‘moderate,’’ also effective November 15, 1990. The ‘‘Imperial Valley planning area’’ was one of the areas listed by EPA in March 1991 as an ‘‘initial’’ PM10 nonattainment area. On November 6, 1991 (56 FR 56694), EPA codified the PM10 nonattainment area designations, including the nonattainment area designation for ‘‘Imperial Valley planning area,’’ in 40 CFR part 81.3 States with ‘‘moderate’’ PM10 nonattainment areas were required under the CAA as amended in 1990 to revise their SIPs to provide for attainment of the PM10 NAAQS no later than December 31, 1994. ‘‘Moderate’’ areas that failed to attain the PM10 NAAQS by December 31, 1994 were subject to reclassification to ‘‘serious.’’ Such reclassification would extend the applicable attainment date to December 31, 2001 but would require the SIP for the area to be further revised to meet more stringent requirements than had applied to ‘‘moderate’’ areas. On August 11, 2004 (69 FR 48792), EPA determined that the Imperial Valley planning area failed to attain the PM10 NAAQS by December 31, 1994 and reclassified the area to ‘‘serious.’’ The listing of the ‘‘Imperial Valley planning area’’ in the PM10 area designations table in 40 CFR 81.305 without further description has led to some confusion as to the precise boundaries of the designated nonattainment area, and the purpose of today’s direct final rule is to clarify the description of the ‘‘Imperial Valley planning area’’ to eliminate such confusion. Specifically, we are clarifying in this action that the ‘‘Imperial Valley planning area’’ PM10 nonattainment area is that portion of Imperial County that is defined as follows: Commencing at the southwest corner of Imperial County and extending north along the Imperial-San Diego County line to the northwest corner of Imperial County; then east along the Imperial-Riverside County line to the point of intersection of the eastern boundary line of Hydrologic Unit #18100200; 4 then southeasterly along the eastern boundary line of Hydrologic Unit #18100200 to the Imperial County-Mexico Border; then west along the Imperial County-Mexico Border to the point of the beginning. For the purposes of this action, EPA reviewed the Federal Register documents listed above as well as EPA 3 California area designations are codified at 40 CFR 81.305. 4 Within Imperial County, the northeastern boundary of Hydrologic Unit #18100200 generally follows the crestline of the Chocolate Mountains.

Specifically, EPA found that: • EPA’s 1987 listing of two Group I areas within Imperial County, i.e., the ‘‘Imperial Valley planning area’’ and the ‘‘Yuma planning area,’’ establishes that ‘‘Imperial Valley planning area’’ is a partial county area; • The long-standing use of Hydrologic Units to describe other PM10 area designations in desert areas of California (see, e.g., the PM10 area designations in 40 CFR 81.305 for Coso Junction planning area, Owens Valley planning area, Trona planning area, and Indian Wells planning area) establishes precedent for the use of such units to describe the PM10 area designation for ‘‘Imperial Valley planning area,’’ which is also a California desert area; • EPA staff memorandum dated July 17, 1991 describes the ‘‘Imperial Valley Study Area’’ boundary in terms of latitude and longitude that approximate the hydrologic unit boundary; • EPA staff map, undated but believed to have been prepared in the early 1990s, illustrates the Imperial Valley planning area in terms of the northeastern boundary line for Hydrologic Unit #18100200; • EPA map (dated May 1992) of PM10 area designations within Region IX shows the Imperial Valley nonattainment area as covering that portion of the county east of a line that appears to approximate the northeastern boundary line for Hydrologic Unit #18100200; and • A SIP submittal dated January 11, 1994 for the Imperial Valley planning area from the California Air Resources Board (CARB) to EPA includes a PM10 plan that describes the nonattainment area as containing ‘‘most of Imperial County (approximately 80%) except for the portion east of the Chocolate Mountain Range’’ and includes a figure that illustrates the nonattainment area showing a northeastern boundary line that approximates the boundary for Hydrologic Unit #18100200.5 Through today’s action, EPA is not changing the boundaries of the Imperial Valley planning area PM10 nonattainment area, but is simply clarifying the boundaries of the existing PM10 nonattainment area by providing a more detailed description herein and in 40 CFR 81.305. EPA is also not changing the status or classification of the Imperial Valley planning area PM10 nonattainment area. As such, the area 5 See pages 1–2 and 1–3 of the Imperial Valley PM10 Plan submitted by CARB on January 11, 1994.

EPA’s Final Action EPA is clarifying that the Imperial Valley planning area PM10 nonattainment area is that portion of Imperial County that is defined as follows: Commencing at the southwest corner of Imperial County and extending north along the Imperial-San Diego County line to the northwest corner of Imperial County; then east along the Imperial-Riverside County line to the point of intersection of the eastern boundary line of Hydrologic Unit #18100200; then southeasterly along the eastern boundary line of Hydrologic Unit #18100200 to the Imperial County-Mexico Border; then west along the Imperial County-Mexico Border to the point of the beginning. EPA is not changing the boundaries of the PM10 area or the status of the area as a ‘‘serious’’ PM10 nonattainment area but is simply clarifying the description of this partial county area and amending the applicable table in 40 CFR 81.305 accordingly. EPA is publishing this rule without prior proposal because we view this as a non-controversial action and anticipate no adverse comments. However, in the proposed rules section of this Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the SIP revision if relevant adverse comments are received. This rule will be effective on May 20, 2013 without further notice unless we receive adverse comments by April 18, 2013. If we receive adverse comments, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. We will address all public comments in a subsequent final rule based on the proposed rule. We will not institute a second comment period on this action.

In addition, this action does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the action simply clarifies the description of existing air quality planning area and thus will not impose substantial direct costs on Tribal governments or preempt Tribal law. 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 United States. EPA will submit a PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register.

Overview According to the Centers for Medicare & Medicaid Services (CMS) data, as of October 2011, there were 15,720 longterm care (LTC) facilities (commonly referred to as nursing homes) in the United States. These facilities are generally referred to as skilled nursing facilities (SNFs) in the Medicare program and as nursing facilities (NFs) in the Medicaid program. For the past decade, CMS Survey and Certification Tabulation of Certification and Survey Provider Enhanced Reporting (CASPER) data have shown a decline in the number of nursing homes, from 17,508 in 1999 to 15,720 in 2011. In 2010, there were 141 nursing home closures. In 2011, there were 90 closures. LTC facility closures have implications related to access to care, the quality of care, availability of services, and the overall health of residents. Therefore, having an organized process that facilities must follow in the event of a nursing home closure will protect residents’ health and safety, and make the transition as BILLING CODE 6560–50–P DEPARTMENT OF HEALTH AND HUMAN SERVICES Centers for Medicare & Medicaid Services Medicare and Medicaid Programs; Requirements for Long-Term Care (LTC) Facilities; Notice of Facility Closure Centers for Medicare & Medicaid Services (CMS), HHS.

I. Background

    EPA sets the National Ambient Air Quality Standards (NAAQS) for 
certain ambient air pollutants at levels required to protect public 
health and welfare. Particulate matter with an aerodynamic diameter 
less than or equal to a nominal ten micrometers, or PM10, is 
one of these ambient air pollutants for which EPA has established 
health-based standards.
    EPA revised the NAAQS for particulate matter on July 1, 1987 (52 FR 
24633), replacing standards for total

[[Page 16793]]

suspended particulates (TSP less than 30 microns in diameter) that were 
set in 1971 with new standards applying only to particulate matter up 
to 10 microns in diameter (PM10). Simultaneously, EPA 
published revised requirements for state implementation plans (SIPs) to 
attain and maintain the standards (52 FR 24672, July 1, 1987). To focus 
Federal and State resources on implementing the PM10 NAAQS 
first in those areas of the country believed to be violating the 
standards, EPA classified all areas of the Nation into one of three 
groups. Group I areas were those having a very high probability of 
violating the PM10 standards based on ambient air quality 
data available for 1984 through 1987 for PM10 and TSP. Group 
II areas had a moderate probability of violating the standards, and 
Group III areas were those believed to be currently attaining the 
standards.
    A list of Group I and II areas in each State was published on 
August 7, 1987 (52 FR 29383). Within Imperial County,\1\ EPA listed two 
areas, ``Imperial Valley planning area'' and ``Yuma planning area,'' 
\2\ among the Group I areas. The remaining portions of any State not 
listed as Group I or II were classified in Group III.

Imperial County lies within the Sonoran Desert.
    \2\ EPA also listed ``Yuma planning area'' as a Group I area 
within Yuma County, Arizona.
---------------------------------------------------------------------------

    On October 31, 1990 (55 FR 45799), EPA clarified the descriptions 
of several Group I and II areas of concern. In so doing, EPA did not 
clarify the description of the ``Imperial Valley planning area'' but 
did eliminate ``Yuma planning area'' as a Group I or II area of concern 
within Imperial County, California.
    Under section 107(d)(4)(B) of the Clean Air Act (CAA or ``Act''), 
as amended in 1990, certain areas were designated as nonattainment for 
PM10 by operation of law upon enactment of the 1990 
Amendments (i.e., November 15, 1990). These areas included all areas 
included in Group I in EPA's 1987 list (unless changed by EPA prior to 
the 1990 Amended Act) as well as certain Group II and III areas. The 
Imperial Valley planning area, as a former ``Group I'' area, was one of 
the areas designated as a PM10 nonattainment area by 
operation of law effective November 15, 1990.
    On March 15, 1991 (56 FR 11101), EPA announced all of those areas 
that were designated nonattainment for PM10 by operation of 
law and announced that all of the nonattainment areas were classified 
as ``moderate,'' also effective November 15, 1990. The ``Imperial 
Valley planning area'' was one of the areas listed by EPA in March 1991 
as an ``initial'' PM10 nonattainment area. On November 6, 
1991 (56 FR 56694), EPA codified the PM10 nonattainment area 
designations, including the nonattainment area designation for 
``Imperial Valley planning area,'' in 40 CFR part 81.\3\
---------------------------------------------------------------------------

    \3\ California area designations are codified at 40 CFR 81.305.
---------------------------------------------------------------------------

    States with ``moderate'' PM10 nonattainment areas were 
required under the CAA as amended in 1990 to revise their SIPs to 
provide for attainment of the PM10 NAAQS no later than 
December 31, 1994. ``Moderate'' areas that failed to attain the 
PM10 NAAQS by December 31, 1994 were subject to 
reclassification to ``serious.'' Such reclassification would extend the 
applicable attainment date to December 31, 2001 but would require the 
SIP for the area to be further revised to meet more stringent 
requirements than had applied to ``moderate'' areas. On August 11, 2004 
(69 FR 48792), EPA determined that the Imperial Valley planning area 
failed to attain the PM10 NAAQS by December 31, 1994 and 
reclassified the area to ``serious.''
    The listing of the ``Imperial Valley planning area'' in the 
PM10 area designations table in 40 CFR 81.305 without 
further description has led to some confusion as to the precise 
boundaries of the designated nonattainment area, and the purpose of 
today's direct final rule is to clarify the description of the 
``Imperial Valley planning area'' to eliminate such confusion. 
Specifically, we are clarifying in this action that the ``Imperial 
Valley planning area'' PM10 nonattainment area is that 
portion of Imperial County that is defined as follows: Commencing at 
the southwest corner of Imperial County and extending north along the 
Imperial-San Diego County line to the northwest corner of Imperial 
County; then east along the Imperial-Riverside County line to the point 
of intersection of the eastern boundary line of Hydrologic Unit 
18100200; \4\ then southeasterly along the eastern boundary 
line of Hydrologic Unit 18100200 to the Imperial County-Mexico 
Border; then west along the Imperial County-Mexico Border to the point 
of the beginning.
---------------------------------------------------------------------------

    \4\ Within Imperial County, the northeastern boundary of 
Hydrologic Unit 18100200 generally follows the crestline of 
the Chocolate Mountains.
---------------------------------------------------------------------------

    For the purposes of this action, EPA reviewed the Federal Register 
documents listed above as well as EPA memoranda and State planning 
documents. Based on that review, EPA confirmed the accuracy of the 
above description. Specifically, EPA found that:
     EPA's 1987 listing of two Group I areas within Imperial 
County, i.e., the ``Imperial Valley planning area'' and the ``Yuma 
planning area,'' establishes that ``Imperial Valley planning area'' is 
a partial county area;
     The long-standing use of Hydrologic Units to describe 
other PM10 area designations in desert areas of California 
(see, e.g., the PM10 area designations in 40 CFR 81.305 for 
Coso Junction planning area, Owens Valley planning area, Trona planning 
area, and Indian Wells planning area) establishes precedent for the use 
of such units to describe the PM10 area designation for 
``Imperial Valley planning area,'' which is also a California desert 
area;
     EPA staff memorandum dated July 17, 1991 describes the 
``Imperial Valley Study Area'' boundary in terms of latitude and 
longitude that approximate the hydrologic unit boundary;
     EPA staff map, undated but believed to have been prepared 
in the early 1990s, illustrates the Imperial Valley planning area in 
terms of the northeastern boundary line for Hydrologic Unit 
18100200;
     EPA map (dated May 1992) of PM10 area 
designations within Region IX shows the Imperial Valley nonattainment 
area as covering that portion of the county east of a line that appears 
to approximate the northeastern boundary line for Hydrologic Unit 
18100200; and
     A SIP submittal dated January 11, 1994 for the Imperial 
Valley planning area from the California Air Resources Board (CARB) to 
EPA includes a PM10 plan that describes the nonattainment 
area as containing ``most of Imperial County (approximately 80%) except 
for the portion east of the Chocolate Mountain Range'' and includes a 
figure that illustrates the nonattainment area showing a northeastern 
boundary line that approximates the boundary for Hydrologic Unit 
18100200.\5\
---------------------------------------------------------------------------

    \5\ See pages 1-2 and 1-3 of the Imperial Valley PM10 
Plan submitted by CARB on January 11, 1994.
---------------------------------------------------------------------------

    Through today's action, EPA is not changing the boundaries of the 
Imperial Valley planning area PM10 nonattainment area, but 
is simply clarifying the boundaries of the existing PM10 
nonattainment area by providing a more detailed description herein and 
in 40 CFR 81.305. EPA is also not changing the status or classification 
of the Imperial Valley planning area PM10 nonattainment 
area. As such, the area

[[Page 16794]]

remains designated as ``nonattainment'' for PM10 and 
classified as ``serious.''

II. EPA's Final Action

    EPA is clarifying that the Imperial Valley planning area 
PM10 nonattainment area is that portion of Imperial County 
that is defined as follows: Commencing at the southwest corner of 
Imperial County and extending north along the Imperial-San Diego County 
line to the northwest corner of Imperial County; then east along the 
Imperial-Riverside County line to the point of intersection of the 
eastern boundary line of Hydrologic Unit 18100200; then 
southeasterly along the eastern boundary line of Hydrologic Unit 
18100200 to the Imperial County-Mexico Border; then west along 
the Imperial County-Mexico Border to the point of the beginning. EPA is 
not changing the boundaries of the PM10 area or the status 
of the area as a ``serious'' PM10 nonattainment area but is 
simply clarifying the description of this partial county area and 
amending the applicable table in 40 CFR 81.305 accordingly.
    EPA is publishing this rule without prior proposal because we view 
this as a non-controversial action and anticipate no adverse comments. 
However, in the proposed rules section of this Federal Register 
publication, we are publishing a separate document that will serve as 
the proposal to approve the SIP revision if relevant adverse comments 
are received. This rule will be effective on May 20, 2013 without 
further notice unless we receive adverse comments by April 18, 2013. If 
we receive adverse comments, we will publish a timely withdrawal in the 
Federal Register informing the public that the rule will not take 
effect. We will address all public comments in a subsequent final rule 
based on the proposed rule. We will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
now.

III. Statutory and Executive Order Reviews

    This action simply clarifies the description of an existing air 
quality planning area and would not impose additional requirements 
beyond those imposed by state law. For that reason, this action:
     Is not ``significant regulatory actions'' 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 economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not significant regulatory actions subject to Executive 
Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address disproportionate human health or environmental effects with 
practical, appropriate, and legally permissible methods under Executive 
Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this action does not have Tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the action simply clarifies the description of existing air 
quality planning area and thus will not impose substantial direct costs 
on Tribal governments or preempt Tribal law.
    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 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States 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).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by May 20, 2013. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. Parties with objections to this direct final rule are 
encouraged to file a comment in response to the parallel notice of 
proposed rulemaking for this action published in the proposed rules 
section of today's Federal Register, rather than file an immediate 
petition for judicial review of this direct final rule, so that EPA can 
withdraw this direct final rule and address the comment in the proposed 
rulemaking. This action may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
