## Executive Summary

Purpose of the report

The De partment of Ecology (Ecology) reviews its ambient air quality monitoring network annually to

ensure that it collects adequate, representative, and useful air quality data. This report gives the results of

the 2007 review, including :

 I dentif ying modificat ions to Ecology’s ambient air monitoring network since the 2006 annual

network re port

 Identif ying proposed modifications to the network for the upcoming year

 Document ing Ecology’s ambient air quality monitoring needs, goals and prio r ities



### Background i nf

ormation

The United States E nvironmental Protection 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 Imp lementation Plans (SIPs). An air quality surveillance system

consists of a network of monitoring stations designated as 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 requirements of 40 CFR Part 58 contained in :

 Appendi x A (Quality Assurance Requirements)

 Appendix C (Ambient Air Quality Monitoring Methodology)

 Appendix D (Network Design Criteri a)

 Appendix E (Probe and Path Siting Criteria)

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

performance audits (per Section 2.4 of Appendix A )

. States conform with Appendices D and E by

conducting an annu al 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 ne eded to enable an organization to meet its objectives

### Ecology Page 2 4/1/2013

Using monitoring d ata

Ecology uses its air monitoring data to:

 D eterm in e compliance with the national ambient air quality standards (NAAQS)

 D etermin e maximum pollutant concentrations

 Forecast air quality

 Evaluat e 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

### 1.0 Introduction

The Code of Federal Regulations, Title 40, Part 58 (40 CFR Part 58) contains the EPA ’s ambi ent 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

monitoring stations designated as SLAMS . These stations measure ambient concentrations of those air

pollutants for which standards exist in 40 CFR Part 50 and Part 58, Appendices A (Quality Assurance

Requirements), C (Ambient Air Quality Monitoring Methodology), D (Network Design Crit eria) and E

(Probe and Path Siting Criteria). States determine c onformance with Appendices A and C in part through

periodic systems and performance audits (per Section 2.4 of Appendix A )

. States conform with

Appendices D and E by conducting an annual netw ork 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

The annual network review determines 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 ambient air quality monitoring

network collects adequate, representative, and useful air quality data. The ambient air quality data from

the State of Washington , Department of E colog y’s ( Ecology’s ) network is used for a variety of purposes

including:

 determining compliance with the national ambient air quality standards (NAAQS),

 determining the location of maximum pollutant concentrations,

 determining the effectiveness of air pollu tion control programs,

 evaluating the effects of air pollution on public health,

 tracking the progress of SIPS,

 supporting dispersion models

 developing responsible, cost

- effective control strategies,

 developing air quality trends.

### 2.0 Regulatory Req uirements and Other Data Needs

2.1 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.



### 2.1.1 Monitoring Objectives and Spatial Scales

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

(1) to determine the highest pollutant concentrations expected in the area covered by the network;

(2) to determine representative pollutant concentrations in areas of high population density;

(3) to de termine the impact of significant sources or source categories on pollutant concentrations in

the ambient air;

(4) to determine general background pollutant concentrations;

(5) to determine the regional extent of pollutant transport between populated are as, and

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

areas on the secondary (i.e., welfare) standards.

SLAMS networks should be designed to provide data for meeting the monitoring objectives des cribed

above and to assist the EPA and States in solving environmental problems.

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

network (Table 2

- 1). Ideally, the monitor is located so that its sample rep resents the air quality over the

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

- 2).

### 2.1.2 Number of SLAMS Sites

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

SLAMS network except that a minimum number of SLAMS lead, SO 2 , and PM 2.5 sites are required. For

lead, EPA is requiring State and local agencies to focus their network design efforts on establishing

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 five or more tons per year or smaller stationary sources which may be

problematic based on the size of the facility and their proximity to populated neighborhoods.

EPA recommends a minimum of two lead sites per source, one to measure stack impacts and the second

to measure fugitive emissions. Other factors such as topography, source type, proximity and locations of

nearby populations may 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 of

SO 2 in the airshed, as listed in Table 2

- 3. 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 tradeoffs between data needs and available resources which can best be

resolved during the network desig n process.

b In addition, one NAM population

lead violations have been measured over the most recent 8 calendar quarters.

### Ecology Page 8 4/1/2013

2.2 Appendix E Requirements

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

general site location has been selected based on the monitoring objectives 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 2

- 6.

EPA believes that most sampling probes or monitors can be located so that they meet the Appendix E

siting requirements. Some existing stations, however, may not meet these requirements and yet still

produce useful data for some purposes. EPA will consider written requests from the State to waive one or

more siting criteria for some monitoring stations provided that the State can demonstrate the following:

(1) the site is as representative of the monitoring area as it would be if siting cri teria were met; and (2) the

siting criteria cannot be met because of physical constraints (e.g., inability to locate the station the

necessary setback distance from roadways or obstructions). Waivers may be granted to existing SLAMS

if one of these criter ia is met; waivers may be granted for new SLAMS only if both criteria are met.

W ritten requests for waivers must be submitted to the EPA Regional Administrator.

2.3 Other Ambient Air Monitoring Data Needs

Washington has a number of special purp ose monitors (SPMs) deployed throughout the State for PM 10 , PM 2.5 , CO and NO 2 , monitoring. They are used for a variety of purposes, including Washington’ s Air

Quality Index program, ambient air quality assessment and special studies such as secondary aero sol 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 pollut ant monitoring sites allows Ecology to 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 year s 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.

protrudes above the sampler, probe, or monitoring path. Sites not meeting this cri terion may be classified as middle scale.

e Must have unrestricted airflow 270  around the probe or sampler; 180  if the probe is on the side of a building.

f The probe, sampler, or monitoring path should be away from minor sources, such as furnace or incine ration flues. The separation

distance is dependent on the height of the minor source ’ s emission point (such as flue), the type of fuel or waste burned, and the

quality of the fuel (sulfur, ash, or lead content). This criterion is designed to avoid undue influences from minor sources.

g For microscale CO monitoring sites, the probe must be .10 meters from a street intersection and preferably at a midblock loca tion.

h For collocated Pb and PM 10 samplers, a 2

- 4 meter separation distance between collocated samp lers must be met.

### 3.0 Network Review Procedure

3.1 Network Review Team and Preparation

Network re port participants include Washington Department of Ecology Air Monitoring staff and where

applicable, representatives from Washington’s seven local air agenc ies . S ufficient information must be

provided to determine conformance of the network with regulatory network design and siting

requirements specified in 40 CFR Part 58, Appendices D and E as well as to determine conformance of

the network design and siting requirements specified for all special ambient air monitoring networks.



### 3.2 Network Modifications

Modifications to the SLAMS network are addressed in 40 CFR 58.25, 58.36, a nd 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 indicated by the

annual network review required b y 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 should be recommended as a result of this annual re port

.

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

monitoring 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 si tes

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

- investment

should be made and on what schedule.

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

modificatio ns 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 consistently 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.



### 3.3 Determining Conformance w ith Appendix D and Special Monitorin g Requirements

With regard to Appendix D requirements, this network review is intended to determine the adequacy of

the network in terms of number and location of monitors. Specifically, (1) is Ecology meeting the

number of monitors required by the Part 58 Appendix D design criteria requirements; (2) are the

monitors properly located based on the monitoring objectives and spatial scales of representativeness

presented in Appendix D. For special monitoring networks, conformance determinations will be

cond ucted in accordance with program documents applicable to the special networks.

### Ecology Page 11 4/1/2013

3.3.1 Number and Location of Monitors

For SLAMS the number of monitors required, and their location s , is not specified in the regulations but

rather is determined by EPA Region 10 and Ecology on a case

- by

- case basis to meet the monitoring

objectives specified in Appendix D. Adequacy of the network may be determined by using a variety of

tools, including the following:

 analyses of historical monitoring data,

 maps of em issions densities,

 dispersion modeling,

 special studies/saturation sampling,

 best professional judgement,

 SIP requirements,

 revised monitoring strategies (e.g., new regulations, reengineering air monitoring network),

 monitoring network maps and network des criptions with site objectives defined.

Appropriate location of monitors can be determined on the basis of stated objectives. Maps, graphical

overlays, and GIS

- based information are extremely helpful in visualizing or assessing the adequacy of

monitor loc ations. Plots of potential emissions and/or historical monitoring data versus monitor locations

are especially useful. When questions arise about the adequacy of a particular location, modeling or

special studies (including saturation monitoring studies) may be appropriate.

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 obtained from the lat est census data and ambient monitoring data from

AQS . If the 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 speci al monitoring serving AQI, etc., program documents applicable to the network must be reviewed

to determine the goals and specific siting criteria for the network. Conformance with monitoring

objective determinations of the special network should be conduc ted using procedures similar to those

used for Appendix D evaluations (i.e., are the number of monitors appropriate and are the monitors

properly located).



### 3.4 Determining Conformance w ith Appendix E Requirements

Applicable siting criteria for SLAM S 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 cover, etc.

4. 8 Trace Gas Monitoring

NCore

– Precursor Gas & Multi

- Pollutant Monitoring

– From an emission source perspective,

multiple pollutan ts 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 remo val 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.

O verwhelming programmatic and scientific interactions across pollutant s have demanded a movement

toward integrated air quality management. Collocated air monitoring benefit s health assessments and

emissions strategy development. Health studies with access to multi

- pollutant data will be better

positioned to identify confou nding effects 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. Modele rs 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. A s emission sources are

characterized by a multiplicity of pollut ant releases, 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

performance.

The multi

- pollutant monitoring provide d 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 ti mely reporting 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.

Gas Monitoring Programs currently underway, Beacon Hill is also a designated National Air Toxics

Tren d Site (NATTS). The primary objectives of Washington’s National Air Toxics Trends Site

Monitoring Program include but are not limited to :

 Provide long

- term air toxic monitoring data in order to establish and track trends.

 Evaluate the air toxic program’s progress by c haracterizing air toxics concentrations, and

determining their spatial and temporal differences between cities and regions over time.

 Provide representative air toxic data to s upport exposure assessments (i.e. determine health risks).

 Determin e where air toxics emissions come from (source apportionment).

 Provide air toxic data for evaluating modeling results that are used for exposure assessments.

 Assess the effectiveness of the air toxic program’s emission reduction and control strategies.

 Determine the spatial and temporal differences of PM 2.5 composition between cities and regions

over time.

 Provide representative PM 2.5 speciation data to s upport exposure assessments (i.e . determine

health risks).

 Determine where PM 2.5 emissions come from (source apportionment).

 Evaluate modeling results that are used for exposure assessments.

 Assess the effectiveness of the program’s emission reduction and control strategies.
