The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Nevada. On July 3, 2008, the EPA redesignated the Truckee Meadows area, consisting largely of the cities of Reno and Sparks in Washoe County, Nevada, from nonattainment to attainment for the carbon monoxide (CO) National Ambient Air Quality Standards (NAAQS) and approved the State's plan addressing the area's maintenance of the NAAQS for ten years. On November 7, 2014, the State of Nevada submitted to the EPA a second maintenance plan for the Truckee Meadows area that addressed maintenance of the NAAQS through 2030. The EPA is now approving this second maintenance plan. The EPA is also finding adequate and approving transportation conformity motor vehicle emissions budgets (MVEBs) for the years 2015, 2020, 2025 and 2030. We are taking these actions under the Clean Air Act (CAA or ``the Act'').

Air Plan Approval; Reno, Nevada; Second 10-Year Carbon Monoxide 
Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action to approve a State Implementation Plan (SIP) revision 
submitted by the State of Nevada. On July 3, 2008, the EPA redesignated 
the Truckee Meadows area, consisting largely of the cities of Reno and 
Sparks in Washoe County, Nevada, from nonattainment to attainment for 
the carbon monoxide (CO) National Ambient Air Quality Standards (NAAQS) 
and approved the State's plan addressing the area's maintenance of the 
NAAQS for ten years. On November 7, 2014, the State of Nevada submitted 
to the EPA a second maintenance plan for the Truckee Meadows area that 
addressed maintenance of the NAAQS through 2030. The EPA is now 
approving this second maintenance plan. The EPA is also finding 
adequate and approving transportation conformity motor vehicle 
emissions budgets (MVEBs) for the years 2015, 2020, 2025 and 2030. We 
are taking these actions under the Clean Air Act (CAA or ``the Act'').

DATES: This rule is effective on October 31, 2016 without further 
notice, unless the EPA receives adverse comments by September 29, 2016. 
If we receive such comments, we will publish a timely withdrawal in the 
Federal Register to notify the public that this direct final rule will 
not take effect.

I. Background

A. Truckee Meadows Attainment Status

    Under the CAA Amendments of 1990, the Truckee Meadows area 
(hereinafter referred to as Truckee Meadows, the Truckee Meadows area 
or the area), which includes the Reno-Sparks metropolitan area in 
Washoe County, Nevada, was designated and classified as a moderate CO 
nonattainment area.\1\
---------------------------------------------------------------------------

    \1\ For a detailed description of air quality planning in the 
area, see the EPA's proposal to approve the first 10-year 
maintenance plan, published in the Federal Register on January 7, 
2008, 73 FR 1175 at 1177. The CO attainment table in 40 CFR 81.329 
lists the area as ``Reno Area: Washoe County (part) Truckee Meadows 
Hydrographic Area 87.''
---------------------------------------------------------------------------

    The primary CO NAAQS are attained when ambient concentration design 
values do not exceed either the 1-hour 35 parts per million (ppm) (or 
10 milligrams per cubic meter) standard or the 8-hour 9 ppm (or 40 
milligrams per cubic meter) standard more than once per year. See 40 
CFR 50.8(a). According to monitoring data going back to 1980 in the 
EPA's \2\ Air Quality System (AQS), Truckee Meadows has not had a 
violation of the 1-hour CO standard.\3\ Regarding the 8-hour standard, 
the area has not had a violation since 1991.\4\ The EPA determined in 
2005 that the area had attained the CO NAAQS by the area's December 31, 
1995 attainment deadline. See 70 FR 22803 (May 3, 2005). This 
determination did not affect the designation of the area as 
nonattainment or its classification as a moderate area.
---------------------------------------------------------------------------

    \2\ The initials EPA, and the words ``we,'' ``us,'' or ``our'' 
mean or refer to the United States Environmental Protection Agency.
    \3\ See Truckee Meadows 1980-2016 1-Hour CO Violation Day Count 
Report, data pulled from AQS on August 1, 2016.
    \4\ 2014 Maintenance Plan, page 1. See also, Truckee Meadows 
1991-2016 8-Hour CO Violation Day Count Report, data pulled from AQS 
on August 1, 2016, which verifies the District's assertion in the 
2014 Maintenance Plan that there have been no 8-hour CO violations 
in the Truckee Meadows area since 1991. This report also includes 
more recent monitoring data (up through the first quarter of 2016) 
than the 2014 Maintenance Plan.
---------------------------------------------------------------------------

    On November 4, 2005, the State of Nevada (``State'' or ``Nevada'') 
submitted a request to the EPA to redesignate Truckee Meadows from 
nonattainment to attainment for the CO NAAQS. Along with this request, 
the State submitted a CAA section 175A(a) maintenance plan, which 
demonstrated that the area would maintain the CO NAAQS for the first 10 
years following our approval of the redesignation request (``2005 
Maintenance Plan''). We approved the State's redesignation request and 
10-year maintenance plan on April 2, 2008. See 73 FR 38124 (July 3, 
2008). For a detailed history of the CO planning efforts in the area up 
to 2005, please see the EPA's proposal to approve the 2005 Maintenance 
Plan. See 73 FR 1175 at 1177 (January 7, 2008).

B. 2014 Maintenance Plan

    Eight years after an area is redesignated to attainment, CAA 
section 175A(b) requires the State to submit a subsequent maintenance 
plan to the EPA, covering a second 10-year period.\5\ The second 
maintenance plan must demonstrate continued compliance with the NAAQS 
during this second 10-year period. To fulfill this requirement of the 
CAA, Nevada submitted the second 10-year update of the Truckee Meadows 
area CO maintenance plan to the EPA on November 7, 2014. The plan was 
developed by the Washoe County Health District's (District) Air Quality 
Management Division (AQMD) and is titled ``Second 10-Year Maintenance 
Plan for the Truckee Meadows 8-Hour Carbon Monoxide Attainment Area, 
August 28, 2014'' (hereinafter, ``2014 Maintenance Plan'' or ``Plan''). 
The 2014 Maintenance Plan was adopted by the District's Board of Health 
on August 28, 2014. See Washoe County Board of Health Certificate of 
Adoption, August 28, 2014. Air quality planning and monitoring in 
Truckee Meadows is the responsibility of the District, which 
administers air quality programs in Washoe County through the AQMD. The 
State Environmental Commission and the Nevada Department of Motor 
Vehicles are responsible for the motor vehicle inspection and 
maintenance program in Truckee Meadows.
---------------------------------------------------------------------------

    \5\ In this case, the initial maintenance period extends through 
2018. Thus, the second 10-year period must extend at least through 
2028. The District's demonstration is for maintenance through 2030.
---------------------------------------------------------------------------

C. Transportation Conformity

    Section 176(c) of the Act defines conformity as meeting the SIP's 
purpose of eliminating or reducing the severity and number of 
violations of the NAAQS and achieving expeditious attainment of such 
standards. The Act further defines transportation conformity to mean 
that no Federal transportation activity will: (1) Cause or contribute 
to any new violation of any standard in any area; (2) increase the 
frequency or severity of any existing violation of any standard in any 
area; or (3) delay timely attainment of any standard or any required 
interim emission reductions or other milestones in any area. The 
federal transportation conformity rule, 40 CFR part 93 subpart A, sets 
forth the criteria and procedures for demonstrating and assuring 
conformity of transportation plans, programs and projects which are 
developed, funded or approved by the U.S. Department of Transportation, 
and by metropolitan planning organizations or other recipients of 
Federal funds under Title 23 U.S.C. or the Federal Transit Laws.
    The transportation conformity rule applies within all nonattainment 
and maintenance areas. As prescribed by the transportation conformity 
rule, once an

[[Page 59492]]

area has an applicable SIP with MVEBs, the expected emissions from 
planned transportation activities must be consistent with such 
established budgets for that area.

II. The EPA's Evaluation of Nevada's Submittal

    The 2014 Maintenance Plan contains the following major sections: 
(1) An introductory section containing a general discussion of plan 
approvals and the area's redesignation to attainment; and (2) a 
maintenance plan section including subsections on the attainment 
emissions inventory, a maintenance demonstration, MVEBs, the area's 
monitoring network, verification of continued attainment, and a 
contingency plan. See 2014 Maintenance Plan, Chapters 1 and 2.
    Following is the EPA's evaluation of the 2014 Maintenance Plan 
under the CAA, the EPA's implementing regulations and relevant 
guidance.

A. Ambient Air Quality Monitoring Data

    As noted above, the primary NAAQS for CO are: 9 ppm (or 10 
milligrams per cubic meter) for an 8-hour average concentration not to 
be exceeded more than once per year and 35 ppm (or 40 milligrams per 
cubic meter) for a 1-hour average concentration not to be exceeded more 
than once per year. See 40 CFR 50.8(a).
    The 2014 Maintenance Plan includes a summary of 8-hour CO design 
values for the years 2008 to 2013. See 2014 Maintenance Plan, Table 1-
1, page 2. In addition, the EPA examined monitoring data for Truckee 
Meadows for the last ten years, including a large portion of the period 
covered by the first maintenance plan. Table 1 shows the complete, 
quality assured and certified ambient air monitoring design values for 
CO in the area for the years 2006 to 2015 and preliminary data for 
2016. The first maintenance plan covers the years 2008-2018. The year 
2015 is the last year for which we have complete, quality assured and 
certified ambient air monitoring design values for CO in the area. The 
monitoring data show that CO design values in the Truckee Meadows area 
have been well below the level of the NAAQS throughout the last decade.
---------------------------------------------------------------------------

    \6\ Design values were derived from AQS. The EPA notes that the 
8-hour CO design value given in the 2014 Maintenance Plan for the 
year 2011 (i.e., 2.9 ppm) appears to be in error and should actually 
be as shown (i.e., 2.6 ppm). For 1-hour CO design values, see the 
Truckee Meadows 1-Hour CO 2006-2016 Maximum Values Report, dated 
August 1, 2016. For 8-hour CO design values, see the Truckee Meadows 
8-Hour CO 2006-2016 Maximum Values Report, dated August 1, 2016.
    \7\ Preliminary design values for 2016 through March 31, 2016. 
See Truckee Meadows 2016 1-hour Completeness Report, dated August 1, 
2016.

B. Attainment Inventory

    Due to the area's status at the time as moderate nonattainment for 
the CO standards, the District developed a 1990 baseline emissions 
inventory and has continued to update the inventory pursuant to CAA 
requirements every three years. The most recent inventory at the time 
the state submitted the 2014 Maintenance Plan was for the year 2011. 
The District is using the 2011 emissions inventory, adjusted down due 
to unusually high wildfire emissions that occurred that year, as the 
attainment inventory. The District refers to this attainment inventory 
as the Truckee Meadows maintenance emissions limit. With the level of 
emissions that occurred in 2011, the area still attained the CO 
standards. Levels at or below the downward-adjusted 2011 emissions 
(that is, the Truckee Meadows maintenance emissions limit) are 
therefore expected to maintain the standards. The unadjusted emissions 
levels are presented in Table 2. The District then adjusts the nonpoint 
source category to reflect more representative wildfire emissions, and 
then uses the adjusted total emissions for the area as the maintenance 
emissions limit, as explained in section III.C below.

                       Table 2--2011 CO Inventory
------------------------------------------------------------------------

                                                               day)
------------------------------------------------------------------------

                                                         ---------------
  Total *...............................................         372,522
------------------------------------------------------------------------
* Totals may not add up due to rounding.

    The EPA finds that the 2011 inventory information presented by the 
District is acceptable and consistent with the source category amounts 
and totals for the 2011 National Emissions Inventory for Washoe County, 
with one exception. The District's information does not account for 
railroad (locomotive) emissions. Locomotive emissions would add 3.6 
tons per year of CO emissions to the area, or 19.7 pounds per day (lbs/
day). Compared to a total inventory of 372,522 lbs/day, however, the 
omission of railroad emissions amounts to less than 0.01% of the total 
CO emissions for the area, and the EPA therefore does not believe the 
omission to be significant.

C. Maintenance Demonstration

    In general, a state may demonstrate that an area will maintain the 
NAAQS by showing that future emissions will not exceed the level of the 
attainment inventory.\8\ Attainment must be demonstrated for the 10-
year period following the first ten years covered by the initial 
maintenance plan. For the Truckee Meadows area, the first maintenance 
period ranges from 2008, when the EPA approved the area's redesignation 
request and maintenance plan, through the year 2018. In the 2014 
Maintenance Plan, the District must also demonstrate attainment for the 
10-year period following the first ten years. The 2014 Maintenance Plan 
covers a portion of the first 10-year period (through 2018), as well as 
the second ten years, 2018 through 2028. In addition, a state may go 
beyond the minimum requirements of the CAA. The District has elected to 
make the horizon year for this Plan 2030 for the convenience of 
transportation planning.
---------------------------------------------------------------------------

    \8\ See the EPA's September 4, 1992 John Calcagni memorandum 
entitled ``Procedures for Processing Requests to Redesignate Areas 
to Attainment,'' at page 9, available online at: https://www.epa.gov/sites/production/files/2016-03/documents/calcagni_memo_-_procedures_for_processing_requests_to_redesignate_areas_to_attainment_090492.pdf.
---------------------------------------------------------------------------

    Although the 2005 Maintenance Plan addresses maintenance through 
the year 2018, the emissions projections of the 2014 Maintenance Plan 
replace those from the previous plan. The District's rationale is that 
there are now better

[[Page 59493]]

planning assumptions and improved emissions calculation methodologies 
that were not available in developing the previous plan. Updated 
methodologies include the change from using MOBILE6 mobile source 
modeling software, used for the 2005 Maintenance Plan, to the MOVES 
model used for the 2014 Maintenance Plan.
    As noted above, the District used its 2011 periodic emissions 
inventory \9\ to develop the baseline 2011 ``maintenance emissions 
limit'' for the Truckee Meadows area, which is then used to compare 
future emissions inventories for the purpose of verifying continued 
attainment of the CO NAAQS as long as those future emissions are lower 
than the maintenance emissions limit.
---------------------------------------------------------------------------

    \9\ See Washoe County, Nevada: 2011 Periodic Emissions Inventory 
and Appendices A, B, and C.
---------------------------------------------------------------------------

    As shown in Table 3, for most emissions categories, the District 
simply used emission levels from the 2011 periodic emissions inventory 
to develop its 2011 maintenance emissions limit. However, for 
wildfires, the District noted that 2011 was an unusually active year 
for wildfires, with corresponding CO emissions of 105,092 lbs/day. To 
approximate more typical wildfire emissions for purposes of producing 
the 2011 Truckee Meadows maintenance emissions limit, the District used 
the average of wildfire emissions for the four previous inventory years 
(1999, 2002, 2005, and 2008). That average is 217 lbs/day, which the 
District used to adjust the nonpoint source category. Due to this 
adjustment, total nonpoint emissions for the nonpoint source category 
are 50,081 lbs/day for the maintenance emissions limit, as compared 
with 154,956 lbs/day in the 2011 emissions inventory, as shown in Table 
3. See 2014 Maintenance Plan, Table 2-3.

    The District supports its use of 267,648 lbs/day maintenance 
emissions limit as the attainment inventory because it uses the most 
accurate emissions inventory methodologies, is a current and 
comprehensive emissions inventory, identifies the level of emissions in 
the Truckee Meadows area sufficient to maintain the CO standards, and 
will be the emissions inventory most consistent with the 2030 projected 
inventory required for demonstrating maintenance of the CO standards. 
See 2014 CO Maintenance Plan, page 6.
    The District used the following methodologies or models, as 
described in EPA guidance,\11\ to project the 2011 maintenance 
emissions limit (i.e. the 2011 periodic emissions inventory adjusted to 
exclude unusually high wildfire emissions) out to future milestone 
years 2015, 2020, 2025 and 2030 for each of the emissions source 
categories, in order to demonstrate continued maintenance with the CO 
NAAQS.
---------------------------------------------------------------------------

    \10\ See ``Procedures for Preparing Emissions Projections,'' 
EPA-450/4-91-019, July 1991, available online at https://www.epa.gov/nscep.
---------------------------------------------------------------------------

    1. Baseline Emissions Projections. Washoe County's 2030 population, 
employment and vehicle miles travelled (VMT) forecasts (2014 
Maintenance Plan, Appendix A) were used as surrogates to project the 
2030 emissions, and were consistent with those used by the local 
metropolitan planning organization.
    2. EPA Models. Non-road and on-road motor vehicle categories 
accounted for approximately 59% of the 2011 emissions inventory. To 
ensure consistency throughout the maintenance demonstration period, the 
same non-road and on-road models were used to estimate the 2030 
projected emissions inventory.
    3. Emissions Category Surveys. The District uses surveys to 
estimate emissions from residential wood combustion (RWC). The District 
applied an adjustment factor based on heating degree days to the most 
recent survey (conducted in 2012-2013) to project RWC emissions from 
2015 through 2030. See 2014 Maintenance Plan, Appendix A.1
    Table 4 lists the 2011 Truckee Meadows maintenance emissions limit 
and projected emissions for 2015, 2020, 2025 and 2030 for the four 
major CO emissions source categories in the area. See 2014 Maintenance 
Plan, Table 2-4. The District provides a more detailed inventory for 
2011 and projected future years in the 2014 Maintenance Plan, Appendix 
B.

    The District projects that population, number of households, 
employment and VMT will increase through 2030 and beyond, but that 
federally enforceable CO control programs targeting gasoline-powered 
motor vehicles, RWC and diesel-powered motor vehicles will help offset 
this growth. Because future emissions are not projected to exceed the 
level of the 2011 Truckee Meadows maintenance emissions limit of 
267,648 lbs/day, the District asserts that the CO NAAQS will be 
maintained through the maintenance demonstration period.\11\
---------------------------------------------------------------------------

    \11\ Although the summary paragraph following Table 2-4 in the 
plan compares future year projections shown in the table to the 
``2011 Truckee Meadows maintenance emissions inventory,'' EPA 
believes that the District clearly intended to make the comparison 
to the ``Truckee Meadows Maintenance Emissions Limit,'' as the 
District stated in this single-asterisk (*) note to the table. See 
2014 Maintenance Plan, page 7.
---------------------------------------------------------------------------

    The EPA agrees with the District's conclusion. Even with the growth 
expected in the area in the future, overall emissions of CO in the area 
are declining and provide assurance that the area will not violate the 
CO standard in the future. With respect to wildfire emissions, we find 
that the District's approach of adjusting both the attainment inventory 
(i.e., the maintenance emissions limit) and the projected future year 
emissions inventories to exclude unusually high 2011 wildfire emissions 
is reasonable.

D. Transportation Conformity

    Transportation conformity is required by section 176(c) of the CAA. 
Conformity to a SIP means that transportation activities will not 
produce new air quality violations, worsen existing violations, or 
delay timely attainment of the NAAQS. See CAA section 176(c)(1)(B). The 
EPA's conformity rule at 40 CFR part 93, subpart A requires that 
transportation plans, programs and projects conform to SIPs and 
establishes the criteria and procedures for determining whether or not 
they conform. To effectuate its purpose, the conformity rule generally 
requires a demonstration that emissions from the Regional 
Transportation Plan and the Transportation Improvement Program are 
consistent with the MVEBs contained in the applicable control strategy 
SIP revision or maintenance plan. See 40 CFR 93.101, 93.118, and 
93.124. An MVEB is defined as the level of mobile source emissions of a 
pollutant relied upon in the attainment or maintenance demonstration to 
show compliance with the NAAQS in the nonattainment or maintenance 
area.\12\
---------------------------------------------------------------------------

    \12\ Further information concerning the EPA's interpretations 
regarding MVEBs can be found in the preamble to the EPA's November 
24, 1993, transportation conformity rule (see 58 FR 62193-62196).
---------------------------------------------------------------------------

    The EPA's process for determining adequacy of a MVEB consists of 
three basic steps: (1) Notifying the public of a SIP submission; (2) 
providing the public the opportunity to comment on the MVEB during a 
public comment period; and, (3) making a finding of adequacy or 
inadequacy. See 40 CR 93.118(f). In order for us to find an MVEB 
adequate and approvable, the submittal must meet the conformity 
adequacy provisions of 40 CFR 93.118(e)(4) and (5). The 2005 
Maintenance Plan established CO MVEBs (in terms of pounds per typical 
CO season day) of 330,678 pounds per typical CO season day in year 2010 
and 321,319 pounds per typical CO season day in year 2016. The EPA 
found the CO MVEBs adequate for transportation conformity purposes 
effective March 30, 2006 (March 15, 2006, 71 FR 13386) \13\ and 
approved the MVEBs on July 3, 2008 (73 FR 38124).

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

    The 2014 Maintenance Plan establishes new MVEBs for CO, as shown in 
Table 5.

 Table 5--Transportation Conformity Motor Vehicle Emissions Budgets for the Truckee Meadows CO Maintenance Area

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

    The District developed these MVEBs using emissions inventory 
projections for the years 2015 through 2030. The MVEBs include on-road 
vehicles, heavy duty diesel vehicle idling, and a safety margin. The 
latter is the excess emissions between the total projected emissions 
for a specific year and the 2011 maintenance emissions limit. We note 
that the MVEBs in the 2014 Maintenance Plan differ from those contained 
for similar years in the 2005 Maintenance Plan. These differences are 
due to the use of the latest planning assumptions for the 
transportation network, including VMT, vehicle speeds and vehicle 
population for passenger cars and trucks, in the development of the 
Washoe County 2011 periodic emissions inventory. As in previous 
periodic emissions inventories, these planning assumptions were 
consistent with those used by the local metropolitan planning 
organization for their transportation plans.
    We are not announcing the availability of these MVEBs through the 
EPA's Adequacy Web site and providing a separate comment period on the 
adequacy of the MVEBs. Instead, we are reviewing the adequacy of the 
MVEBs simultaneously with our review of the 2014 Maintenance Plan 
itself. See 40 CFR 93.118(f)(2). In order to determine whether these 
MVEBs are adequate and approvable, we have evaluated whether the MVEBs 
meet the conformity adequacy provisions of 40 CFR 93.118(e)(4) and (5) 
and have determined that the MVEBs meet the applicable criteria. These 
criteria include, for example, that the MVEBs are clearly identified 
and precisely quantified, that the Plan shows a clear relationship 
among the emissions budgets, control measures and the total emissions 
inventory, among other criteria. The details of the EPA's evaluation of 
the MVEBs are provided in a memo to file for this rulemaking.\14\

    In accordance with the State's request and the EPA's evaluation, 
with this action the EPA finds adequate and approves CO MVEBs for the 
years 2015, 2020, 2025 and 2030. Upon the effective date of this 
action, the Washoe County Regional Transportation Commission and the 
U.S. Department of Transportation must use these budgets in future 
conformity analyses. Any and all comments on the adequacy and 
approvability of the 2015, 2020, 2025 or 2030 MVEBs should be submitted

E. Ambient Air Quality Monitoring Network

    The District has maintained an ambient air quality monitoring 
network in Washoe County, including the Truckee Meadows area, in 
accordance with the EPA's ambient air quality monitoring network 
regulations in 40 CFR part 58. Monitors are operated by the District, 
and they submit an Annual Network Plans (ANPs) for the County to the 
EPA.
    The EPA is currently reviewing the 2016 ANP submitted by the 
District.\15\ The EPA approved the District's previous ANPs, the most 
recent three of which were submitted to the EPA by the District in 
2013,\16\ 2014 \17\ and 2015.\18\ The docket to this action includes 
these approvals and the associated ANPs, as well as the ANP currently 
under review.

County Health District, dated October 21, 2015.
---------------------------------------------------------------------------

    In addition to reviewing the District's ANPs, the EPA performs 
Technical Systems Audits (TSAs) of ambient air monitoring programs in 
accordance with 40 CFR part 58, appendix A, section 2.5, which requires 
that the EPA conduct a TSA of each primary quality assurance 
organization (PQAO) every three years. A PQAO is an organization that 
is responsible for a set of stations that monitor the same pollutant 
and for which data quality assessments can be pooled. The District is 
the PQAO for CO monitoring in Washoe County, which includes the Truckee 
Meadows area. See 40 CFR 58.1.
    The most recent TSA for the District was conducted by the EPA in 
2016, but the report for that TSA has not yet been finalized. The most 
recent TSA for which the final report is available was conducted in 
2013. The EPA found that the District's air monitoring program was 
robust and met the EPA's requirements. There were no findings that were 
cause for data invalidation.\19\
---------------------------------------------------------------------------

    \19\ See letter from Deborah Jordan, Director, U.S. EPA Region 9 
Air Division, to Charlene Albee, Director, Air Quality Management 
Division, Washoe County Health District, dated August 19, 2014, 
transmitting a report titled ``Technical System Audit Report, Washoe 
County Health District Air Quality Management Division Ambient Air 
Monitoring Program (September 4-6, 2013).''
---------------------------------------------------------------------------

    In the 2014 Maintenance Plan, the District commits to continued 
operation of its CO monitoring network, in accordance with 40 CFR part 
58, to verify the attainment status of the Truckee Meadows area. See 
2014 Maintenance Plan, page 8. In addition, the District will continue 
to review the Washoe County CO monitoring network pursuant to 40 CFR 
58.10 to ensure the network meets the monitoring objectives defined in 
40 CFR part 58, appendix D. Funding for the monitoring network to meet 
its objectives has been derived in the past primarily from CAA section 
105 grants and the State's Department of Motor Vehicles. The District 
commits to maintaining these funding sources. See 2014 Maintenance 
Plan, page 8.
    The District commits to the continuation of collecting and quality-
assuring ambient CO monitoring data in accordance with 40 CFR part 58 
and to providing the data to the EPA's AQS. The data will therefore be 
available for public review. See 2014 Maintenance Plan, page 9.
    Table 6 lists the active Washoe County CO monitoring sites 
identified in the Plan. See 2014 Maintenance Plan, page 9, Table 2-7. 
As noted in the footnotes to the table, two of the monitoring sites 
have since discontinued CO monitoring (i.e., South Reno and Galletti), 
and the District has indicated that it intends to submit to the EPA a 
request to shut down two more sites (i.e., Toll and Lemmon Valley). The 
EPA notes that the Lemmon Valley monitoring site is within Washoe 
County but is not located in the Truckee Meadows area.

------------------------------------------------------------------------
* The District discontinued CO monitoring at the South Reno and Galletti
  monitoring sites in 2014. Details of these network modifications, as
  well as copies of the EPA's approval letters, can be found in the
  District's 2015 ANP (Appendices A and B).
** In its 2016 ANP, the District indicates it will seek EPA approval to
  discontinue CO monitoring at the Toll and Lemmon Valley monitoring
  sites, but will not discontinue monitoring at these locations without
  such approval. See the District's 2016 ANP.

    The District is required to maintain a CO monitor at the Reno3 
site. See 40 CFR part 58, appendix D, section 3. Other CO monitoring 
sites are not required for Washoe County by the EPA's minimum 
monitoring requirements. See 40 CFR part 58, appendix D, section 4.2.
    Based on the information in the 2014 Maintenance Plan, as well as 
recent ANPs and the 2013 TSA report, the EPA has determined that the 
area's air quality monitoring network meets the requirements of the CAA 
and implementing regulations in 40 CFR part 58.

F. Verification of Continued Attainment

    To support the District's continued operation and maintenance of 
the Washoe County ambient CO monitoring network, the District also 
commits to tracking actual CO emissions, in order to identify potential 
increases in ambient CO concentration. The District has three existing 
mechanisms to track CO emissions.
    1. Periodic Emissions Inventories. The District commits to 
continuing to prepare and submit to the EPA a

[[Page 59496]]

comprehensive periodic CO emissions inventory on a triennial schedule. 
Prior to submittal of the 2014 Maintenance Plan, the last periodic 
emissions inventory prepared was for the year 2011. See 2014 
Maintenance Plan, page 9. In addition, the District has prepared and 
submitted to the EPA a periodic emissions inventory for the area for 
2014.
    2. Consolidated Emissions Reporting Rule (CERR) and Air Emissions 
Reporting Rule (AERR). The EPA's AERR (40 CFR part 51 subpart A), which 
incorporates the former CERR, requires regular updates of point and 
area emissions sources within Washoe County. The District commits to 
continued compliance with the CERR and AERR. See 2014 Maintenance Plan, 
page 10.
    3. Residential Wood Use Survey. RWC is a significant source of CO 
emissions during the winter in Truckee Meadows. Between 1993 and 2013, 
the District completed nine residential wood use surveys. These surveys 
estimated the device (i.e., fireplace, woodstove and pellet stove) 
population, the amount of wood burned, and CO emissions from RWC in 
Washoe County. As part of the 2014 Maintenance Plan, the District 
renews the commitment it made in the 2005 Maintenance Plan to conduct a 
residential wood use survey at least once every three years. See 2014 
Maintenance Plan, page 10.
    The EPA agrees with the District that continued ambient air 
monitoring and emissions tracking will ensure verification of continued 
attainment and maintenance of the 8-hour CO NAAQS within the Truckee 
Meadows area.

G. Contingency Plan

    Section 175A of the CAA requires that a maintenance plan include 
contingency provisions, as necessary, to promptly correct any violation 
of a NAAQS that occurs after the redesignation to attainment of an area 
for that NAAQS. As a maintenance area for CO, this requirement applies 
to Truckee Meadows. According to the EPA's guidance,\20\ the 
contingency plan for a maintenance area should clearly identify the 
following:
---------------------------------------------------------------------------

    \20\ EPA's September 4, 1992 memorandum entitled ``Procedures 
for Processing Requests to Redesignate Areas to Attainment,'' at 
page 12, available online at: https://www.epa.gov/sites/production/files/2016-03/documents/calcagni_memo_-_procedures_for_processing_requests_to_redesignate_areas_to_attainment_090492.pdf.
---------------------------------------------------------------------------

 Specific indicators or triggers that will be used to determine 
when contingency measures need to be implemented;
 contingency measures to be adopted;
 schedule and procedures for adoption and implementation; and
 specific time limit for action.

    The following is the EPA's analysis of the 2014 CO Maintenance 
Plan's contingency plan regarding the above four criteria:
    The 2014 Maintenance Plan identifies significant sources that 
contribute to the highest CO concentrations during the winter CO season 
months, November through January. The 2014 Maintenance Plan includes a 
two-tiered contingency plan based on ambient air monitoring data.
    As part of the EPA's approval into the SIP of the 2005 Maintenance 
Plan, we approved a contingency plan for the area. Part of the 
contingency plan (``Tier 1''), as discussed in greater detail below, 
relies entirely on the area's emergency episode plan. Such plans are 
required under CAA section 110(a)(2)(G). We approved the District's 
emergency episode plan on June 18, 2007 (72 FR 33397).
1. Contingency Plan Tier 1
a. Specific Indicators or Triggers Which Will Be Used To Determine When 
Contingency Measures Need To Be Implemented
    The Tier 1 trigger mechanism is a single exceedance of the 8-hour 
CO standard, that is, a monitored concentration greater than or equal 
to 9 ppm (9.5 ppm to adjust for rounding), at any State and Local Air 
Monitoring Station (SLAMS), Special Purpose Monitoring (SPM) or 
national Core Multi-Pollutant Monitoring Station (NCore) site operated 
within Washoe County. The EPA notes that this trigger is protective of 
the 8-hour CO NAAQS in three respects.
    First, it takes two non-overlapping CO exceedances to violate the 
standard. The CAA requires that, at a minimum, contingency measures be 
triggered when the standard is violated. In the 2014 Maintenance Plan, 
the District is committing to triggering this Tier 1 portion of its 
contingency plan with a single exceedance. This entails implementation 
of a contingency measure upon an exceedance of the CO NAAQS, before the 
NAAQS is violated.
    Second, the trigger for Tier 1 can occur at any monitor in the 
County. This is more protective of the CO NAAQS than would otherwise be 
required by the Act in that the District is required to trigger Tier 1 
using an exceedance of any monitor in Washoe County, rather than 
relying only on the monitors within the Truckee Meadows maintenance 
area within the County.
    Third, implementation of Tier 1 would occur in the entire 
jurisdiction of the District, that is, County-wide. Controls related to 
the Stage 1 Alert episode would be implemented in the entire County, 
which could benefit the Truckee Meadows area within the County.
b. The Contingency Measures To Be Adopted
    As we noted above, the EPA has already approved the District's 
emergency episode plan into the SIP. This emergency plan currently is 
triggered, independent of any contingency plan, during any monitored or 
predicted concentration at a level of 9.4 ppm or above. Once the 
emergency plan is triggered, the duration of its implementation depends 
on the circumstances of the episode, regarding monitored and predicted 
levels of CO.
    In the Tier 1 contingency measure, the District will initiate a 
rulemaking to permanently lower the County-wide Stage 1 Alert 
activation level from 9.4 ppm down to 9.0 ppm. The District will 
initiate this rulemaking if a monitored CO concentration is above 9.4 
ppm (i.e., 9.5 ppm or above). Monitors that can activate Tier 1 include 
any monitor in the entire County, that is, not just within the Truckee 
Meadows area. For informational purposes, Table 7 lists the actions the 
District takes once a Stage 1 Alert level is either recorded or 
predicted for the County. See 2014 Maintenance Plan, page 11. When Tier 
1 is triggered, the District will initiate a specific rulemaking change 
for adoption by the District's Board of Health (WCDBOH). In the event 
Tier 1 is triggered, the District would initiate revision of WCDBOH 
Regulation 050.001, Emergency Episode Plan (adopted March 23, 2006). 
The rule revision would revise the Stage 1 Alert level from the current 
level of 9.4 ppm down to the lower level of 9.0 ppm.

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

c. A Schedule and Procedures for Adoption and Implementation
    The implementation schedule the District identifies in the 2014 
Maintenance Plan is meant to begin the rulemaking process promptly. The 
rule revision must be adopted by the WCDBOH and implemented before the 
next CO season (i.e., November, December and January).
    The District also commits to notify the EPA Region 9 office within 
45 days of the triggering of tier 1. See 2014 Maintenance Plan, page 
11.
d. A Specific Time Limit for Action
    The schedule discussed above provides a specific time limit for 
action by the Board in that the rule revision is to be adopted and 
implemented before the next CO season.
2. Contingency Plan Tier 2
a. Specific Indicators or Triggers Which Will Be Used To Determine When 
Contingency Measures Need To Be Implemented
    The Tier 2 trigger mechanism is a second, non-overlapping 
exceedance of the 8-hour CO standard (i.e., greater than or equal to 
9.5 ppm to adjust for rounding) at any SLAMS, SPM or NCore site 
operated within Washoe County. The EPA notes that only a second non-
overlapping exceedance at the same monitor would constitute a violation 
of the 8-hour CO NAAQS, so this approach is more protective of the 
standard than is required by the form of the standard itself. Also, the 
EPA notes that this trigger is also more protective of the CO NAAQS 
than is required because it goes beyond the boundary of the Truckee 
Meadows area and encompasses the entire Washoe County District.
b. The Contingency Measures To Be Adopted
    For Tier 2, the District will maintain a list of potential 
contingency measures and provide recommendations to the WCDBOH. The 
District's recommendations to the Board will include a timeline for 
adoption and implementation to promptly correct any violation of the CO 
NAAQS. The list of Tier 2 potential contingency measures are shown in 
Table 8. See 2014 CO Maintenance Plan, Table 2-8.

c. A Schedule and Procedures for Adoption and Implementation
    The implementation schedule the District identifies in the 2014 
Maintenance Plan is meant to begin the rulemaking process promptly. No 
later than 45 days after Tier 2 is triggered, recommendations shall be 
presented to the Board at its next regularly scheduled meeting. The 
District commits to review and update as necessary the list of 
potential Tier 2 contingency measures at least once every three years. 
See 2014 Maintenance Plan, page 12. The District also commits to notify 
the EPA Region 9 office within 45 days of the triggering of Tier 2. See 
2014 CO Maintenance Plan, page 12.
d. A Specific Time Limit for Action
    The schedule discussed above for Tier 2 implementation provides a 
specific time limit for action by the Board. Rule revision 
recommendations are to be presented to the Board within a set time 
frame, and the Board will review and update the recommendations, as 
necessary, but not less than once every three years. Further, the time 
frame for the District to provide recommendations to the Board requires 
the District to present at the Board's next scheduled meeting, but no 
later than 45 days after triggering Tier 2. The Board typically meets 
every month.
    Tier 2 also involves a regular review of CO control measures by the 
District and the Board. This review occurs at least once every three 
years regardless of whether there is an exceedance of the CO NAAQS.
3. Contingency Plan Conclusion
    The EPA agrees with the District that prompt action and 
implementation of Tier 1 and Tier 2 contingency measures may prevent 
future exceedances and violations of the 8-hour CO NAAQS. The EPA 
believes the District's two-tiered contingency plan will promptly 
address violations if they do occur. Triggering contingency measures at 
monitored concentration levels that exceed, but do not violate the 
standard, is an important component of this approach.

III. Public Comment and Final Action

    As authorized in section 110(k)(3) of the Act, the EPA is fully 
approving the State of Nevada's second 10-year

[[Page 59498]]

maintenance plan, titled ``Second 10-Year Maintenance Plan for the 
Truckee Meadows 8-Hour Carbon Monoxide Attainment Area, August 28, 
2014.'' We are also approving MVEBs for the years 2015, 2020, 2025 and 
2030.
    We do not think anyone will object to these approvals, so we are 
finalizing them without proposing them in advance. However, in the 
Proposed Rules section of this Federal Register, we are simultaneously 
proposing approval of the same submitted Plan and MVEBs. If we receive 
adverse comments by September 29, 2016, we will publish a timely 
withdrawal in the Federal Register to notify the public that the direct 
final approval will not take effect and we will address the comments in 
a subsequent final action based on the proposal. If we do not receive 
timely adverse comments, the direct final approval will be effective 
without further notice on October 31, 2016. This will incorporate this 
plan into the federally enforceable SIP and require use of the new 
MVEBs in all future CO conformity analyses.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:

 Is not a significant regulatory action subject to review by 
the Office of Management and Budget under Executive Orders 12866 (58 FR 
51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
 does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
 is certified as not having a significant economic impact on a 
substantial number of small entities under the Regulatory Flexibility 
Act (5 U.S.C. 601 et seq.);
 does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
 does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
 is not an economically significant regulatory action based on 
health or safety risks subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997);
 is not a significant regulatory action subject to Executive 
Order 13211 (66 FR 28355, May 22, 2001);
 is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
 does not provide the EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).

    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where the EPA or an Indian tribe 
has demonstrated that a tribe has jurisdiction. In those areas of 
Indian country, the rule does not have tribal implications and will not 
impose substantial direct costs on tribal governments or preempt tribal 
law as specified by Executive Order 13175 (65 FR 67249, November 9, 
2000).
    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. The 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 Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by October 31, 2016. 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 the 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)).

\1\ The organization of this table generally follows from the organization of the State of Nevada's original
  1972 SIP, which was divided into 12 sections. Nonattainment and maintenance plans, among other types of plans,
  are listed under Section 5 (Control Strategy). Lead SIPs and Small Business Stationary Source Technical and
  Environmental Compliance Assistance SIPs are listed after Section 12 followed by nonregulatory or quasi-
  regulatory statutory provisions approved into the SIP. Regulatory statutory provisions are listed in 40 CFR
  52.1470(c).
