Washington: Second 10-Year PM10

Limited Maintenance Plan 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve 

the limited maintenance plan submitted 

on January 4, 2016, by the State of 

Washington for the Spokane area, which 

includes the cities of Spokane, Spokane 

Valley, Millwood and surrounding 

unincorporated areas in Spokane 

County, Washington. This plan 

addresses the second 10-year 

maintenance period for particulate 

matter with an aerodynamic diameter 

less than or equal to a nominal 10 

micrometers (PM10). A limited 

maintenance plan is used to meet Clean 

Air Act requirements for formerly 

designated nonattainment areas that 

meet certain qualification criteria. The 

EPA is proposing to determine 

Washington’s submittal meets the 

limited maintenance plan criteria. The 

Spokane area currently has monitored 

PM10 levels well below the National 

Ambient Air Quality Standards 

(NAAQS) and levels have not increased 

since the area was redesignated to 

attainment in 2005. The EPA is also 

proposing to approve minor updates to 

the Spokane Regional Clean Air Agency 

(SRCAA) regulations controlling PM10

related to the maintenance plan.

I. Background 

The Spokane area was designated as 

nonattainment for PM10 by operation of 

law upon enactment of the Clean Air 

Act Amendments in 1990 (56 FR 56694, 

November 6, 1991). The Washington 

Department of Ecology (Ecology) and 

SRCAA worked with the community to 

establish PM10 pollution control 


Lhorne on DSK5TPTVN1PROD with PROPOSALS
9794 Federal Register / Vol. 81, No. 38 / Friday, February 26, 2016 / Proposed Rules 

1The data evaluated includes a 2013 flagged 

exceptional event that has not been fully evaluated 

by the EPA to date. If this flagged data were factored 

strategies. Primary control strategies 

include a residential wood smoke 

control program, paving unpaved 

streets, requirements for improved 

sweeping and sanding practices on 

paved roads, and regulatory orders at 

the Kaiser Aluminum and Chemical 

Corporation Trentwood facility for 

PM10. The Spokane area attained the 

PM10 NAAQS in 1994, with continued 

attainment ever since. 

The EPA partially approved the PM10

attainment plan for the Spokane area on 

January 27, 1997 (62 FR 3800). The EPA 

then approved the remaining attainment 

plan elements and a 10-year 

maintenance plan, redesignating the 

area from nonattainment to attainment 

effective August 30, 2005 (70 FR 38029, 

published July 1, 2005). The purpose of 

the current limited maintenance plan is 

to fulfill the second 10-year planning 

requirement, section 175A(b) of the 

Clean Air Act, to ensure compliance 

through 2025. 

II. The Limited Maintenance Plan 

Option for PM10 Areas 

A. Requirements for the Limited 

Maintenance Plan Option 

On August 9, 2001, the EPA issued 

guidance on streamlined maintenance 

plan provisions for certain moderate 

PM10 nonattainment areas. See memo 

from Lydia Wegman, Director, Air 

Quality Standards and Strategies 

Division, entitled ‘‘Limited Maintenance 

Plan Option for Moderate PM10

Nonattainment Areas’’ (limited 

maintenance plan option memo). The 

limited maintenance plan option memo 

contains a statistical demonstration that 

areas meeting certain air quality criteria 

will, with a high degree of probability, 

maintain the standard ten years into the 

future. Thus, the EPA provided the 

maintenance demonstration for areas 

meeting the criteria outlined in the 

memo. It follows that future year 

emission inventories for these areas, and 

some of the standard analyses to 

determine transportation conformity 

with the State Implementation Plan 

(SIP) are no longer necessary. 

To qualify for the limited 

maintenance plan option the State must 

demonstrate the area meets the criteria 

described below. First, the area should 

have attained the PM10 NAAQS. 

Second, the most recent five years of air 

quality data at all monitors in the area, 

called the 24-hour average design value, 

should be at or below 98 micrograms 

per cubic meter (mg/m3). Third, the State 

should expect only limited growth in 

on-road motor vehicle PM10 emissions 

and should have passed a motor vehicle 

regional emissions analysis test. Lastly, 

the memo identifies core provisions that 

must be included in all limited 

maintenance plans. These provisions 

include an attainment year emissions 

inventory, assurance of continued 

operation of an EPA-approved air 

quality monitoring network, and 

contingency provisions. 

B. Conformity Under the Limited 

Maintenance Plan Option 

The transportation conformity rule 

and the general conformity rule (40 CFR 

parts 51 and 93) apply to nonattainment 

areas and maintenance areas covered by 

an approved maintenance plan. Under 

either conformity rule, an acceptable 

method of demonstrating a Federal 

action conforms to the applicable SIP is 

to demonstrate that expected emissions 

from the planned action are consistent 

with the emissions budget for the area. 

While qualification for the limited 

maintenance plan option does not 

exempt an area from the need to affirm 

conformity, conformity may be 

demonstrated without submitting an 

emissions budget. Under the limited 

maintenance plan option, emissions 

budgets are treated as essentially not 

constraining for the length of the 

maintenance period because it is 

unreasonable to expect that the 

qualifying areas would experience so 

much growth in that period that a 

violation of the PM10 NAAQS would 

result. For transportation conformity 

purposes, the EPA would conclude that 

emissions in these areas need not be 

capped for the maintenance period and 

therefore a regional emissions analysis 

would not be required. Similarly, 

Federal actions subject to the general 

conformity rule could be considered to 

satisfy the ‘‘budget test’’ specified in 40 

CFR 93.158 (a)(5)(i)(A) for the same 

reasons that the budgets are essentially 

considered to be unlimited. 

Under the limited maintenance plan 

option, emissions budgets are treated as 

essentially not constraining for the 

maintenance period because it is 

unreasonable to expect that qualifying 

areas would experience so much growth 

in that period that a NAAQS violation 

would result. While areas with 

maintenance plans approved under the 

limited maintenance plan option are not 

subject to the budget test, the areas 

remain subject to the other 

transportation conformity requirements 

of 40 CFR part 93, subpart A. Thus, the 

metropolitan planning organization 

(MPO) in the area or the State must 

document and ensure that: 

• Transportation plans and projects 

provide for timely implementation of 

SIP transportation control measures 

(TCMs) in accordance with 40 CFR 

93.113; 

• Transportation plans and projects 

comply with the fiscal constraint 

element as set forth in 40 CFR 93.108; 

• The MPO’s interagency 

consultation procedures meet the 

applicable requirements of 40 CFR 

93.105; 

• Conformity of transportation plans 

is determined no less frequently than 

every four years, and conformity of plan 

amendments and transportation projects 

is demonstrated in accordance with the 

timing requirements specified in 40 CFR 

93.104; 

• The latest planning assumptions 

and emissions model are used as set 

forth in 40 CFR 93.110 and 40 CFR 

93.111; 

• Projects do not cause or contribute 

to any new localized carbon monoxide 

or particulate matter violations, in 

accordance with procedures specified in 

40 CFR 93.123; and 

• Project sponsors and/or operators 

provide written commitments as 

specified in 40 CFR 93.125. 

In approving the 2nd 10-year limited 

maintenance plan, the Spokane 

maintenance area will continue to be 

exempt from performing a regional 

emissions analysis, but must meet 

project-level conformity analyses as 

well as the transportation conformity 

criteria mentioned above. 

III. Review of the State’s Submittal 

A. Has the State demonstrated that the 

maintenance areas qualify for the 

limited maintenance plan option? 

As discussed above, the limited 

maintenance plan option memo outlines 

the requirements to be met for an area 

to qualify. First, the area should be 

attaining the PM10 NAAQS. Under 40 

CFR 50.6, the primary and secondary 

PM10 NAAQS are attained when the 

expected number of days per calendar 

year with a 24-hour average 

concentration above 150 mg/m3 is equal 

to or less than one. The EPA determined 

that the Spokane area attained the PM10

NAAQS and formally redesignated the 

area from nonattainment to attainment, 

beginning the first 10-year maintenance 

period effective August 30, 2005 (70 FR 

38029, published July 1, 2005). We have 

evaluated the most recent monitoring 

data that shows that the Spokane area 

continues to attain the PM10 NAAQS 

with the number of annual exceedances 

equal to 0.3 for the period 2012 through 

2014, well below the 1.0 threshold for 

meeting the NAAQS.1


Lhorne on DSK5TPTVN1PROD with PROPOSALS
Federal Register / Vol. 81, No. 38 / Friday, February 26, 2016 / Proposed Rules 9795 

into the analysis, the calculated number of annual 

exceedances would drop to 0.0. 

Second, the average design value for 

the past five years of monitoring data 

must be at or below the critical design 

value of 98 mg/m3 for the PM10 NAAQS. 

The critical design value is a margin of 

safety in which an area has a one in ten 

probability of exceeding the NAAQS. 

The 5-year average design value for 

Spokane based on PM10 monitoring data 

from 2009 through 2014 is 80 mg/m3. 

The EPA reviewed the data and 

methodology provided by the State and 

finds that the Spokane area 5-year 

average design value is below the 

critical design value of 98 mg/m3

outlined in the limited maintenance 

plan option memo and therefore, meets 

the requirement for the limited 

maintenance plan option. 

Third, the area must meet the motor 

vehicle regional emissions analysis test 

described in the limited maintenance 

plan option memo. The State submitted 

an analysis showing that growth in onroad mobile PM10 emissions sources 

was minimal and would not threaten 

the assumption of maintenance that 

underlies the limited maintenance plan 

policy. Using the EPA’s methodology, 

the State calculated total growth in onroad motor vehicle PM10 emissions over 

the ten-year period for the Spokane area. 

This calculation is derived using 

Attachment B of the EPA’s limited 

maintenance plan memo, where the 

projected percentage increase in vehicle 

miles traveled over the next ten years 

(VMTpi) is multiplied by the on-road 

mobile portion of the attainment year 

inventory (DVmv), including both 

primary and secondary PM10 emissions 

and re-entrained road dust. The EPA 

reviewed the calculations in the State’s 

limited maintenance plan submittal and 

concurs with the determination that the 

area meets the motor vehicle regional 

emissions analysis test. This test is met 

when (VMTpi × DVmv) plus the design 

value for the most recent five years of 

quality assured data is below the limited 

maintenance plan threshold of 98 mg/

m3. The result for Spokane is 82 mg/m3. 

As described above, the Spokane 

maintenance area meets the 

qualification criteria set forth in the 

limited maintenance plan option memo. 

To ensure these requirements continue 

to be met, the State has committed to 

evaluate monitoring data annually to 

ensure the area continues to qualify for 

the limited maintenance plan option. 

The State will report this information to 

the EPA in the annual monitoring 

network report. 

B. Does the State have an approved 

attainment emissions inventory? 

Pursuant to the limited maintenance 

plan option memo, the State’s 

submission should include an emissions 

inventory which can be used to 

demonstrate attainment of the relevant 

NAAQS. The inventory should 

represent emissions during the same 

five-year period associated with air 

quality data used to determine whether 

the area meets the applicability 

requirements of the limited 

maintenance plan option. 

The limited maintenance plan 

submittal includes an emissions 

inventory based on the State’s 2011 

Triennial Emissions Inventory. This 

inventory is prepared as part of the 2011 

National Emissions Inventory under the 

EPA’s Air Emissions Reporting Rule (73 

FR 76539, December 17, 2008). The 

information was supplemented with 

annual 2011 industrial emissions 

reported to SRCAA and Ecology. The 

2011 base years represent the most 

recent emissions inventory data 

available and is consistent with the data 

used to determine applicability of the 

limited maintenance plan option (i.e., 

having no violations of the PM10

NAAQS). The most significant emission 

source categories for the Spokane area 

are residential wood combustion and 

dust from paved and unpaved roads. 

The 2011 emission inventory results 

compare favorably to the 2002 emission 

inventory submitted with the first 10- 

year limited maintenance plan. 

Particulate matter from residential wood 

combustion has declined by almost one 

half. These emission were 2,052 tons 

per year (tpy) in 2002 versus 1,062 tpy 

in 2011. Particulate matter from 

unpaved roads declined from 5,855 tpy 

in 2002 to 623 tpy in 2011. The only 

significant source category from the 

2002 emission inventory to increase was 

particulate matter from paved roads, 

which increased from 325 tpy in 2002 

to 623 tpy in 2011. Emissions from 

point sources remained relatively stable 

at 147 tpy in 2002 and 160 tpy in 2011. 

The EPA reviewed and is proposing to 

approve the emissions inventory and 

methodology. The emissions inventory 

data supports the State’s conclusion that 

the existing control measures in place 

will continue to protect and maintain 

the PM10 NAAQS. 

C. Does the limited maintenance plan 

include an assurance of continued 

operation of an appropriate EPAapproved air quality monitoring 

network, in accordance with 40 CFR 

Part 58? 

The limited maintenance plan memo 

states, ‘‘[t]o verify the attainment status 

of the area over the maintenance period, 

the maintenance plan should contain a 

provision to assure continued operation 

of an appropriate, EPA-approved air 

quality monitoring network, in 

accordance with 40 CFR part 58.’’ 

SRCAA currently operates a Federal 

Equivalent Method (FEM) Tapered 

Element Oscillating Microbalance 

(TEOM) PM10 monitor. SRCAA commits 

to maintaining a PM10 NAAQS 

compliance monitor through the limited 

maintenance plan period to verify the 

attainment status of the area, confirm 

continued qualification for the limited 

maintenance plan option, and to 

provide a means for triggering 

contingency measures if needed. The 

EPA last approved the State’s 

monitoring network in a letter dated 

October 28, 2015, included in the 

docket for this action. Table 1 shows 

98th percentile PM10 monitored values 

at the site to provide a sense of trends 

since the area came into attainment in 

2005.

D. Does the plan meet the Clean Air Act 

requirements for contingency 

provisions? 

Clean Air Act section 175A states that 

a maintenance plan must include 

contingency provisions, as necessary, to 

ensure prompt correction of any 

violation of the relevant NAAQS which 

may occur after redesignation of the area 

to attainment. SRCAA Regulation 1 

Section 6.15.G contains additional 

requirements for road paving should the 

EPA find that the Spokane area has 

violated the PM10 NAAQS. The EPA 

approved this provisions into the SIP on 

April 12, 1999 (64 FR 17545). Similarly, 

Regulation 1 Sections 8.07.A.5 and 8.09 

provide for prohibition of the use of 

uncertified woodstoves for the sole 

purpose of meeting Clean Air Act 

requirements for contingency measures, 

which the EPA approved into the SIP on 

January 27, 1997 (62 FR 3800). These 

contingency provisions remain in effect 

today. 

IV. Proposed Action 

The EPA is proposing to approve the 

limited maintenance plan submitted by 

the State of Washington, on January 4, 

2016, for the Spokane PM10 area. If 

finalized, the EPA’s approval of this 

limited maintenance plan will satisfy 

the section 175A Clean Air Act 

requirements for the second 10-year 

period in the Spokane PM10 area. 

Additionally, Ecology and SRCAA 

requested that the EPA update the 

Washington SIP to include minor 

regulatory changes associated with the 

limited maintenance plan adopted in 

2004 and 2007, since the EPA’s last 

approval (64 FR 17545, April 12, 1999). 

These regulatory changes update and 

clarify the general PM10 control 

measures, including minor revisions to 

the emission reduction strategies for 

both paved and unpaved roads. In a 

prior approval on January 27, 1997, the 

EPA inadvertently approved SRCAA 

section 6.05(A) which is a nuisance 

provision addressing the deposition of 

particulate and not related to attainment 

or maintenance of the NAAQS (62 FR 

3800). Ecology and SRCAA requested, 

and the EPA proposes to approve, 

correcting the SIP to remove this 

nuisance provision. A full copy of the 

regulatory changes, in redline/strikeout 

format, is included in Appendix D of 

the State submittal. The EPA reviewed 

these changes and is proposing to 

approve and incorporate by reference 

the updated versions of SRCAA 

Regulation I, sections 6.05, 6.14, and 

6.15, shown in the table below.

V. Incorporation by Reference 

In accordance with requirements of 1

our incorporation by reference of 40 

CFR 52.2470(c)—Table 9 ‘‘Additional 

Regulations Approved for the Spokane 

Regional Clean Air Agency (SRCAA) 

Jurisdiction’’ to reflect the regulations 

shown in the Proposed Action section. 

The EPA has made, and will continue 

to make, these documents generally 

available electronically through 

www.regulations.gov and/or in hard 

copy at the appropriate EPA office (see 

the FOR FURTHER INFORMATION CONTACT

section of this preamble for more 

information). 

VI. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, 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 Clean Air 

Act. 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 the requirements of

Act of 1995 (15 U.S.C. 272 note) because 

this action does not involve technical 

standards; 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, this proposed rule does 

not have tribal implications as specified 

by Executive Order 13175 (65 FR 67249, 

November 9, 2000), because it will not 

impose substantial direct costs on tribal 

governments or preempt tribal law. This 

SIP revision is not approved to apply in 

Indian reservations in the State or any 

other area where the EPA or an Indian 

tribe has demonstrated that a tribe has
