# Executive Summary

Purpose of the report

The Department of Ecology (Ecology) reviews its ambient air quality monitorin g network each year to

ensure that it collects adequate, representati ve, and useful air quality data on which to base policy

decisions. This report summarizes the results of the 201 3 review. These results include:

• I dentif ying modifications to Ecology’s ambient air monitoring network since the 20 1 2 annual

network re port

• Identifying proposed modifications to the network for the upcoming year

• Documenting Ecology’s ambient air quality monitoring needs, goals

, and prio r ities



## Carbon Monoxide, (CO, 42101)

Recommendations/Modifications: Ecology and its partners have divested of traditional CO

monitoring at all except Spokane (3 rd & Washington) and believe continuing to divest is the best use of

state resources.

Additional Monitors: Trace level carbon mo noxide is monitored at the Seattle Beacon Hill and

Cheeka Peak NCore sites. A carbon monoxide monitor is scheduled to be collocated with NO 2 monitoring at the Seattle area near

- roadway site in 2014.



## Ozone (O 3 

## , 44201)

Recommendations/Proposed Modificatio ns: None

Additional Monitors: None. Ecology provides support for ozone monitoring performed by

local air agencies in Anacortes and Spokane. Continue all identified sites



## Nitrogen Dioxide (NO, 42600, 42601, 42612)

Recommendations/Proposed Modificatio ns: Ecology monitors for the reactive nitrogen

species (NOy) at NCore Seattle Beacon Hill which includes NO 2

. Olympic Region Clean Air

Agency (ORCAA) monitors for the reactive nitrogen species (NOy) at Rural NCore Cheeka

Peak. It is assumed most if not al l the NOy measured at Beacon Hill and Cheeka Peak is

composed of NO 2

.

Additional Monitors: One NO 2 monitor will be sited in 2014 as part of the EPA near

- road

network as funding and permitting are allowed. A second near

- road NO 2 monitor is planned for

201 5 if funding and permitting are allowed.

### vi 

## Sulfur Dioxide (SO 2 

## , 42401)

Recommendations/Proposed Modifications: None

Additional Monitors: None



## Particulate Matter 10 (PM 10 

## , 81102)

Recommendations/Proposed Modifications: None

Additional Monitors: Non e. Continue all identified sites

Comment: The Lacey College Street PM 2.5 nephelometer site (530670013) is being used to

assure continued compliance with the PM 10 NAAQS as well as to confirm the Thurston County

Maintenance Area (TCMA) continues to meet th e qualification criteria of EPA’s Limited

Maintenance Plan (LMP) approach.

A 3

- year NPM 10 design value estimate below 150 μg/m 3 demonstrates compliance with the PM 10 NAAQS

for the TMCA . Th is value for 20 10 to 2012 is 4 3 μg/m 3 . A 5

- year NPM 10 design value be low 98 μg/m 3

demonstrates the TCMA continues to qualify for the LMP approach. Th is value for 20 08 to 2012 is 4 5

μg/m 3 . These current design value estimates demonstrate the TCMA complies with the PM 10 standard and

continues to meet EPA’s LMP qualification criteria.



## Particulate Matter 2.5 (PM 2.5 

## , 88101, 88502)

Additional Monitors: Wenatchee Fifth St. was established in late 2012 replace Wenatchee

Alaska.

Recommendations/Modifications: Vancouver 4 th Plain FRM was discontinued 3/13. The

Vancouver FEM is now the primary instrument. Continue all identified sites

Notes: Nephelometers are not EPA equivalent method compliance instruments and design values are

estimates.

Ecology uses the Washington Air Quality Advisory (WAQA) for reporting PM 2.5 to inform a nd protect

citizens of Washington. WAQA reporting is more protective of human health. Ecology’s goal is to keep

24

- hour concentrations below 20 μg/m

. In addition, some monitors in areas of Washington are not intended to be solely NAAQS based.

Certain moni tors are used for protection of human health by calling burn bans during home

heating season, making daily decisions for agricultural burning and health information

- reporting

PM2.5 values.

# Background information

The United States E nvironmental Protect ion Agency (EPA) ambient air quality surveillance regulations

( Code of Federal Regulations, Title 40, Part 58 (40 CFR Part 58) require s tates to establish air quality

surveillance systems in their State Implementation Plans (SIPs). An air quality surveilla nce system

consists of a network of State and Local Air Monitoring Stations (SLAMS) . These stations measure

ambient concentrations of those air pollutants for which 40 CFR Part 50 sets standards

.



# Monitoring network requirements

SLAMS must meet requirem ents of 40 CFR Part 58 contained in:

• Appendi x A (Quality Assurance Requirements)

• Appendix C (Ambient Air Quality Monitoring Methodology)

• Appendix D (Network Design Criteria)

• Appendix E (Probe and Path Siting Criteria)

States determine if they conform to Appendices A and C in part through periodic systems and

performance audits (per Section 2.4 of Appendix A )

. States conform to Appendices D and E by

conducting an annual network review of their air quality surveillance systems (per 40 CFR 58.20(d) )

. The annual network review :

• D etermines if an ambient air quality monitoring network is achieving its required air

monitoring objectives

• I dentifies changes to the network needed to enable an organization to meet its objectives



# Using monitoring data

Ecology us es its air monitoring data to:

• D eterm ine compliance with the N ational A mbient A ir Q uality S tandards (NAAQS)

• D etermin e maximum pollutant concentrations

• Forecast air quality

• Evaluate the effectiveness of air pollution control programs

• E valuat e the effects of air pollution on public health

• T rack the progress of SIPS

• S upport dispersion models

• D e termin e air quality trends

• D evelop responsible and cost

- effective pollution control strategies

• Analyze pollution episodes

• Assist with permitting work

# Introduction

T he Code of Federal Regulations, Title 40, Part 58 (40 CFR Part 58) contains the federal Environmental

Protection Agency’s ( EPA ’s ) ambient air quality surveillance regulations. Section 58.20 requires s tates to

establish air quality surveillance systems in their State Implementation Plans (SIPs). The air quality

surveillance system consists of a network of designated State and Local Air M onitoring stations

( SLAMS ). These stations measure ambient concentrations of those air pollutants for which standards

ex ist in 40 CFR Part 50 and Part 58, Appendices A (Quality Assurance Requirements), C (Ambient Air

Quality Monitoring Methodology), D (Network Design Criteria) and E (Probe and Path Siting Criteria).

States determine compliance with Appendices A and C in pa rt through periodic systems and performance

audits (per Section 2.4 of Appendix A )

. States comply with Appendices D and E by conducting an

annual network review of their air quality surveillance systems (per 40 CFR 58.20(d) )

. The annual

network review de termines if the network achieved its required air monitoring objectives and if it should

be modified (e.g.

, termination, relocation or establishment of monitoring stations) to meet those

objectives. The main purpose of this review is to ensure that an amb ient air quality monitoring network

collects adequate, representative, and useful air quality data on which to base policy decisions . The

ambient air quality data from Ecology’s network is used for a variety of purposes

, including:



### • D etermining compliance with the N ational A mbien t A ir Q uality S tandards (NAAQS)

• D etermining the location of m aximum pollutant concentrations

• D etermining the effectiveness of air pollution control programs

• E valuating the effects of air pollution o n public health

• T racking the prog ress of SIPS

• S upporting dispersion models

• D eveloping responsible, co st

- effective

, control strategies

• D eveloping air quality trends

• Analyze pollution episodes

• Assist with permitting work



# Regulatory Requirements and Other Data Needs

Appendix D Requirements

Appendix D of 40 CFR 58 describes concepts for designing the SLAMS network

. It addresses

monitoring objectives and the criteria for selecting the location and number of air monitoring stations.

The concepts and guidance in Appendix D, as well as other non

- regulatory EPA data needs, should be

considered when evaluating the adequacy of the SLAMS network.



## Monitoring Objectives and Spatial Scales

Appendix D calls for the design of SLAMS networks to meet a minimum of six basic objectives:

(1) D etermine the hi ghest pollutant concentrations expected in the area covered by the network

(2) D etermine representative pollutant concentrations in a reas of high population density

(3) D etermine the impact of significant sources or source categories on pollutant co ncentrations in

the ambient air

### 10 (4) D etermine general back ground pollutant concentrations

(5) D etermine the regional extent of pollutant tr ansport between populated areas

(6) D etermine the impacts (e.g., visibility impairment, vegetation effects) in more rural and remote

areas on th e seco ndary (i.e., welfare) standards

SLAMS networks are designed to provide data for meeting the monitoring objectives described above and

to assist EPA and s tates in solving environmental problems.

Appendix D also provides guidance on spatial scales of representativeness for stations in a SLAMS

network (Table 1). Ideally, the monitor is located so that its sample represents the air quality over the

entire area that the monitoring station is intended to represent (Table 2).

## Number of State and Local Air Monitoring Stations

Appendix D to 40 CFR Part 58 does not co ntain criteria for determining the total number of stations in the

SLAMS network

, except for requiring a minimum number of SLAMS lead, SO 2 , and PM 2.5 sites . For

lead, EPA requires s tate and local agencies to focus their network design efforts on establish ing

monitoring stations around lead stationary sources which generate or have the potential to generate

exceedances of the quarterly lead NAAQS. Sources around which lead monitoring networks should be

established are those emitting half ton or more per ye ar

. Other factors affect the number of stations in the

network.

SLAMS SO 2 monitoring requirements for counties not within the boundaries of any Consolidated

Metropolitan Statistical Area/Metropolitan Statistical Area (CMSA/MSA) are based on the emissions o f

SO 2 in the airsh ed. A minimum number of SO 2 SLAMS sites are required for targeted sources of SO 2 emissions. Other than these requirements, the optimum size of a particular SLAMS network involves

### Page 11 of 59 tradeoffs between data needs and available resources which can best be resolved during the network

design process.



# Appendix E Requirements

Appendix E contains siting criteria to be applied to ambient air quality analyzers or samplers after the

general site location has been selected based on the monitoring objec tives and spatial scales of

representativeness presented in Appendix D and summarized in Section 2.1 of this document. The siting

criteria presented in Appendix E are summarized in Table 3

.



## Other Ambient Air Monitoring Data Needs

Washington has used spe cial purpose monitors (SPMs) throughout the State

. They are used for a variety

of purposes, including Washington’ s Air Quality Advisory program, ambient air quality assessment and

special studies such as secondary aerosol and ozone precursor assessments SPM monitoring sites often

utilize Federal Reference Method (FRM) sampling equipment, and are operated in accordance with CFR

requirements for quality assurance and quality control. SPM designation for criteria pollutant monitoring

sites allows Ecology t o assess ambient particulate levels within regions of the State, while providing the

flexibility to relocate the sites if it is determined there is no concern for NAAQS violations in the area

(typically after three years of data collection). SPM sites may be added to Ecology’ s SLAMS network

when a NAAQS exce e d a nce has been recorded, or if elevated pollutant concentrations are consistently

measured at the site.

# Network Revi ew Procedure

Network Review Team and Preparation

Network re port participants include the W ashington State Department of Ecology Air Quality staff

. S ufficient information is provided to determine compliance of the network with regulatory network

design an d siting requirements specified in 40 CFR Part 58, Appendices D and E as to determine

compliance of the network design and siting requirements specified for all special ambient air monitoring

networks.



## Network Modifications

Modifications to the SLAMS ne twork are addressed in 40 CFR 58.25, 58.36, and 58.46, respectively.

Under Section 58.25, States are required to annually develop and implement schedules to modify the

SLAMS network to eliminate any unnecessary stations or to correct any inadequacies indi cated by the

annual network review required by 58.20(d). As part of the annual network review, evaluations of the

special networks established as partnership agreements between EPA and Ecology should also be

conducted. Modifications to these networks sho uld be recommended as a result of this annual re port

.

### Page 13 of 59 An important objective of the network modification process is determining whether or not sufficient

ambient air quality information and data are being provided by the regulatory and other special

monit oring networks to satisfy the principal data needs. If sufficient air quality data are not being

collected, the deficient area must be identified and corrective action taken to resolve the problem.

Conversely, if it is determined that excessive data are being collected (e.g., there are redundant sites

resulting in data that agree closely), then efforts need to be taken to determine where disinvestment

should be made and on what schedule.

Network modifications may be initiated by EPA or proposed by Ecolog y and agreed to by EPA. Network

modifications may result from revisions to the Part 58 regulations, systems audits, site visits, or

performance evaluations; special studies/saturation sampling, population increases/decreases; air quality

concentrations co nsistently recorded below the NAAQS; loss of permission to use a site; demolition of a

building which is used for monitoring; building construction; growth of trees; changes in roadways;

change in neighborhood type of use, etc.



## Determining Compliance with Appendix D and Special Monitoring

Requirements

Ecology uses this review to determine whether it is meeting the number of monitors required by the Part

58 Appendix D design criteria requirements , and whether the monitors properly located based on the

moni toring objectives and spatial scales of representativeness presented in Appendix D.



### Number and Location of Monitors

For SLAMS

, the number of monitors required and their location s are not specified in the regulations but

rather are determined by EPA Reg ion 10 and Ecology on a case

- by

- case basis . EPA and Ecology ensure

that SLAMS meet the monitoring objectives specified in Appendix D. Adequacy of the network is be

determined by using a variety of tools

. Appropriate location of monitors can be determined on the basis

of stated objectives.

Monitor locations are based on the objectives specified in Appendix D, Section 3. Most often, these

locations are those that have high concentrations and large population exposure. Population information

may be obtain ed from the latest census data and ambient monitoring data from AQS . If zip codes for

various monitoring locations are obtained, use of electronic media census information and GIS

- based

information can be more easily combined with ambient monitoring data.

For special monitoring needs , program documents applicable to the network must be reviewed to

determine the goals and specific siting criteria for the network. Compliance with monitoring objective

determinations of the special network should be conducte d using procedures similar to those used for

Appendix D evaluations (are the number of monitors appropriate and are the monitors properly located).



## Determining Compliance with Appendix E Requirements

Applicable siting criteria for SLAMS are specified in 40 CFR 58, Appendix E. The on

- site visit itself

consists of the physical measurements and observations needed to determine compliance with the

Appendix E requirements, such as height above the ground level, distance from trees, paved or vegetative

ground c over, etc.

## Trace Gas Monitoring

NCore

– Precursor Gas & Multi

- Pollutant Monitoring

– From an emission source perspective,

multiple pollutants and their precursors are released simultaneously (e.g., a combustion plume with

nitrogen, carbon, hydrocarbon, mercury, sulfur gases, and particulate matter). Meteorological processes

that shape pollutant movement, atmospheric transformations, and removal act on all pollutants.

Numerous chemical and physical interactions underlie the dynamics of particle and ozone formation and

the adherence of air toxics on surfaces of particles.

Overwhelming programmatic and scientific interactions across pollutants h ave demanded a movement

toward integrated air quality management. Multi

- pollutant air monitoring benefits health assessments and

emissions strategy development. Health studies with access to multi

- pollutant data will be better

positioned to identify effe cts of different pollutants, particularly when concentration, composition, and

population types are included. Air quality models and source attribution methods used for strategy

development also benefit from the multi

- pollutant approach. Modelers will be able to perform more

robust evaluations by checking performance on several variables to ensure the model produces results for

correct reasons and not through compensating errors. As emission sources are characterized by a

multiplicity of pollutant releas es, related source apportionment models yield more conclusive results from

use of multi

- pollutant measurements. Multi

- pollutant measurements also streamline monitoring

operations and offer increased diagnostic capabilities to improve instrument performanc e.

The multi

- pollutant monitoring provided for these needs by starting to fill the measurement gaps that have

accumulated over the years. The objective of this strategy is to provide for the following important needs :

• Improved data flow and timely repor ting to the public

• Future NAAQS compliance determinations and revisions

• Support for development of emissions strategies

• Assess effectiveness of air pollution control programs

• Data for scientific and health

- based studies

Yakima 24

- Hour PM 2.5 

## NAAQS Compliance, 2010

- 2012

Revised April 30, 2013

Overview

Yakima met EPA’s 75 percent quarterly PM 2.5 data completeness requirement in 2010, 2011 and the first

three quarters of 2012. In the fourth quarter of 2012 completeness was only 73 percent.

Section 4.2(b) of Appendix N to Part 50

— Inte rpretation of the National Ambient Air Quality Standards

for PM 2.5 states

...where the explicit 75 percent quarterly data capture requirement is not met, the 24

- hour PM 2.5 NAAQS DV shall still be considered valid if it passes the maximum quarterly value dat a

substitution test.

The maximum quarterly value data substitution test is valid when the quarterly completeness is less than

75 percent but at least 50 percent. For each quarter not meeting 75 percent data completeness, the highest

PM 2.5 concentration rep orted in the three years under consideration is identified. This maximum quarterly

value is substituted for all missing data in the quarter that does not meet the completeness requirement. If

after substitution, the recalculated test design value is less t han or equal to the level of the standard, then

the “incomplete” PM 2.5 NAAQS design value is deemed to have past the diagnostic test and is valid and

the 24

- hour PM2.5 NAAQS is deemed to have been met in the three

- year period.

Results

The fourth quarter 2012 data completeness of 73 percent failed to meet the 75 percent data completeness

requirement. The highest PM 2.5 concentration reported for the fourth quarter of 3

- year period 2010

- 2012

was 39.0 μg/m 3 in 2011. After substitution of this maximum quarterl y value for all missing 2012 fourth

quarter data, the 2012 98 th percentile is 39.0 μg/m 3 and the 2010

- 2012 diagnostic test design value is 35

μg/m 3 , which meets the 24

- hour PM 2.5 NAAQS. As a result the “incomplete” design value of 31.0 μg/m 3

is deemed to h ave passed the diagnostic test and is valid. As a result Yakima is deemed to have met the

24

- hour PM 2.5 NAAQS in 2010

- 2012.

Yakima, WA Continuous PM 2.5 

## Monitor Assessment

2013 Annual Monitoring Network Plan

April 10, 2013

BACKGROUND

The SLAMS site for monitoring fine particulate (PM 2.5 ) in Yakima, WA is located at 4 02 South 4 th Ave.

The SLAMS site 53

- 077

- 0009 uses a filter

- based Federal Reference Method (FRM) sampler to determine

PM 2.5 concentrations.

On October 4, 2011 a PM 2.5 continuous Federal Equivalent Method (FEM) monitor started operating at

the same site. Th e FEM monitor was designated a Special Purpose Monitor (SPM) to allow time to gain

experience with monitor operation and to evaluate measured concentrations against the FEM. Federal

regulations allow a SPM to operate for 24 months before collected data ar e eligible for comparison to the

NAAQS. The local air agency, Yakima Regional Clean Air Agency, adjusted the monitor to improve

operation through the first 9 months of operation. The final adjustments were made on July 17, 2012.

Newly adopted federal regu lations (40 CFR §58.10(b) (13) and §58.11(e)) allow the State of Washington

to use the annual monitoring report as the vehicle for determining whether data from a continuous PM 2.5 FEM of sufficient quality to be compared to the NAAQS. Washington State’s as sessment and

recommendation follow.

YAKIMA PM 2.5 FEM ASSESSMENT

Tim Hanley and Adam Reff (2011) developed methods for assessing continuous PM 2.5 monitors (see also

EPA, 2012). “Hanley statistics” were developed for the South 4 th Ave monitoring site i n Yakima for all

valid, quality

- assured FRM

- FEM data pairs between October 4, 2011 and December 29, 2012. Attached

“two

- pager” graphical analyses of individual FRM

- FEM data pairs show data from the FEM monitor

adjustment period in red and data after July 1 7, 2012 final adjustment in green. The performance criteria

of 40 CFR 58.11(e) apply to the analysis as follows:

(1) The acceptable concentration range may include values down to 0 μg/m 3 . There were no 0 μg/m 3

values in the data set. The lowest concentration w as 1.1 μg/m 3

. (2) The minimum number of sampling sites shall be at least one. The Yakima site meets these

criteria

. (3) The minimum number of methods shall include at least one FRM and at least one FEM. The

Yakima site has one R & P 2025 PM 2.5 sequential FRM sampl er and one Thermo 1400 TEOM

with 8500 FDMS FEM monitor.

(4) The regulation specifies the precision statistic does not apply to a monitoring network assessment.

(5) All seasons must be covered with no more than 36 consecutive months of data aggregated

together. The analysis addresses 15 consecutive months (October 2011

– December 2012) which

cover all four seasons as defined by Hanley (see EPA, 2012): Winter, December 21 to March 20;

Spring, March 21 to June 20; Summer, June 21 to September 20; and Fall, September 21 to

December 20.

(6) The key statistic metric is the bias both additive and multiplicative of the PM 2.5 continuous FEM

compared to the collocated FRM. Correlation is required to be reported but failure to meet the

correlation criteria is not by itself a reason to exclude data from a continuous FEM monitor.

### Page 51 of 59 These metrics are addressed on the attached “two

- pager” summary of assessment results.

 The additive and multiplicative bias assessments are shown in the additive vs. multiplicative

bias summary graphic and the individual seasonal assessments. These indicate the following

o All data (October 2011 to December 2012) and Fall data (September 21 to December

20) meet acceptable limits

o Winter data (December 21 to March 20), Spring data (March 21 to June20), and

Summ er data (June 21 5o September 20) do not meet acceptable limits.

 The FEM

- FRM correlation is shown on the continuous FEM(y) vs. FRM(x) PM 2.5 graphic.

y = 0.96x + 1.82

R = 0.95

 The correlation coefficient calculations shown on the R(y) vs. FRM CCV(x ) graphic indicate

o Fall and Winter data meet the minimum correlation coefficient limits for FEM

approval.

o All data falls just below the minimum correlation coefficient for FEM approval.

o Summer data does not meet the minimum correlation coefficient for FEM approval.

o Spring data fails to meet not just the minimum correlation coefficient for FEM

approval but the minimum correlation coefficient for AQI reporting as well.

The above in combination with the graphics in the attachment make it clear that for the dat a set as a whole

there is a high correlation between FRM and FEM data, the data set as whole meets acceptable additive

and multiplicative bias limits, and arguably has an acceptable correlation coefficient. However this is not

the entire story.

Adjustments were made to the continuous FEM to improve performance until July 17, 2011. The data set

for this assessment extends through the end of 2012. In effect the data set for the continuous FEM

monitor as it is running today cover only two seasons (Summer and F all 2012). Without a longer data

records we cannot know how all the adjustments made through July 17, 2012 have affected monitor

performance for better or worse.

An examination of the FRM

- FEM difference graphic indicates that positive and negative differe nces are

not spread randomly throughout the year. Examination of the seasonal graphics confirms that the FEM

always reads higher than the FRM in the Spring and Summer. The observed difference is as great as

15 μg/m 3 in September 2012. On the other hand the re is a tendency made more definite after the final July

adjustment for FRM concentrations to be higher than FEM values in the Fall and Winter.

Examining seasonal rather than the data set as a whole, only Fall meets acceptable additive and

multiplicative b ias limits. As stated above EPA’s regulations consider bias to be the key statistical metric.

RECOMMENDATIONS

In light of the Hanley statistics for the data set as a whole and individual seasons and the continual

adjustments made to the continuous PM 2.5 mo nitor to July 2012, the state of Washington recommends the

following:

1. The continuous PM 2.5 FEM monitor should not be used in comparisons of monitoring data to the

PM 2.5 NAAQS for period covered by the 2013 annual monitoring network plan.

2. The Yakima, WA con tinuous PM 2.5 FEM monitor should be assessed for its suitability for

comparison to the PM 2.5 NAAQS in the 2014 annual monitoring network plan.

### 52 We note as an SPM Yakima, WA continuous PM 2.4 FEM monitor data is not currently compared to the
