1 Purpose

Code of Federal regulations, 40 CFR 58.10, requires the state and local air quality surveillance agencies to write an 

annual ambient air quality monitoring network plan. EPA requires the plan to be put out for public comment and 

submitted to EPA by July 1st. This report is used to determine if the network meets the monitoring objectives 

defined in Part 58, Appendix D and to propose modifications to the network in the following year. A more detailed 

air quality data summary is available annually at http://www.deq.state.or.us/aq/forms/annrpt.htm .

2 Introduction

The Oregon Department of Environmental Quality’s (ODEQ) ambient air quality monitoring network is 

designed in response to the Environmental Protection Agency’s (EPA) National Monitoring Strategy, state and 

local needs, the requirements of air quality maintenance plans and the State Implementation Plans (SIPs) for 

non-attainment areas, and CFR requirements.

2.1 National Monitoring Strategy

The National Monitoring Strategy directs state and local agencies to operate more continuous monitors and to 

collect real time air quality data. The real time information is available through EPA’s AIRNow and ODEQ’s 

Air Quality Index (AQI) web pages. In particular, EPA encouraged states to use continuous PM2.5 monitors 

instead of the filter base samplers which do not provide real time information. The National Monitoring 

Strategy also created National Core (NCORE) sites which contain a wide array of pollutant monitoring. 

ODEQ’s NCORE site has monitors for Carbon monoxide (CO), Nitrogen oxides (NOx), Sulfur dioxide (SO2), 

ozone (O3), particulate matter 2.5 and 10 micrometers in diameter and smaller (PM2.5 and PM10), PM coarse 

(PM10-PM2.5=PMc), PM2.5 Speciation, visibility, black carbon, and meteorology. Our proposed NCORE site is 

at SE Lafayette, Portland

State and Local Support

Our monitors support state and local needs by providing data for the Wildfire Air Quality Rating (WAQR), 

local wood stove management programs, Clean Air Quality Advisories for ozone, the Department of 

Agriculture’s field burning program, and the US Forest Service and BLM’s forest health program. ODEQ also 

operates a visibility network in the Cascades and near the Eagle Cap wilderness to support Regional Haze 

requirements protecting pristine Class 1 areas.

AQ Maintenance and Non-attainment support

ODEQ monitoring supports the SIPs and maintenance plans developed for many cities. ODEQ also has 

monitors in attainment areas with fast growing populations to support pollution prevention measures. 

CFR requirements

Monitoring objectives were established and siting was selected in accordance with Appendix D of 40 CFR 58. 

The network was designed to meet the five basic monitoring objectives specified by federal regulations:
2

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

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

(3) to determine the impact of significant sources or source categories on ambient pollution levels;

(4) to determine general background concentration levels; and

(5) to determine transport characteristics into and out of airsheds.

The current network was sited to ensure the spatial scale of the sampling matches the monitoring objective of the 

station. Each station in the SLAMS/NCORE network was sited in accordance with the criteria in 40 CFR Part 58, 

Appendix E. Quality Assurance requirements have been fully implemented through the Department's Quality 

Assurance Plan reviewed by EPA.

2.2 Non-attainment and Maintenance Areas

Areas are designated attainment or non-attainment a few years after a standard is proposed. If an area exceeds 

the standard a State Implementation Plan (SIP) is written to bring an area into attainment. After monitoring 

shows a non-attainment area has reached attainment, a maintenance plan is created to keep it there. Listed 

below are Oregon’s current non-attainment and maintenance areas. 

2.2.1 Non-attainment Areas:

CO: None

PM10 : Eugene/Springfield Urban Growth Area (maintenance plan in development)

Oakridge Urban Growth Boundary (maintenance plan in development)

8hr Ozone None

PM2.5 Klamath Falls Urban Growth Boundary

Oakridge Urban Growth Boundary

2.2.2 Maintenance Areas in Oregon (formerly non-attainment areas):

CO: Eugene/Springfield Area 

Grants Pass Central Business District

Portland Metropolitan Service District Boundary

Klamath Falls Urban Growth Boundary

Medford Urban Growth Boundary

Salem-Kaiser Area Transportation Study 

PM10: Grants Pass Urban Growth Boundary 

Klamath Falls Urban Growth Boundary 

Medford-Ashland Air Quality Maintenance Area 

La Grande Urban Growth Boundary 

Lakeview Urban Growth Boundary

3 Major Network Modifications between July 2009 and June 2010

All major modifications to the ambient air quality monitoring network are submitted to the regional administrator 

for review and approval in the network assessment. Modifications occurring after the 2009 Network Assessment 

are as follows:

DEQ 

1) Set up and operated the Tubman School Air Toxics site from Sept to November 2009, as part of the School 

Air Toxics (SAT) project.

2) Started up a new PM2.5, nephelometer, and meteorology site at Burns Washington Street (41-025-0003) for 

comparison to existing site at Burns Madison Street (41-025-0002). Burns city officials were concerned 

that the Madison Street site was impacted by a chimney 13 meters away. The Washington Street site is 

ideally located away from any nearby sources yet situated in the same neighborhood about four blocks 

away. 

3) Shut down Burns Madison Street site on March 31st, 2010. Comparison of the results from the two sites 

showed little difference between the sites.

4) Relocated the PM2.5 Speciation sampler from Medford Grant and Belmont (41-029-0133) to Lakeview –

Center and M St. (41-037-0001) in September of 2009.

5) Started monitoring for wet Mercury Deposition January 1, 2010 as part of the National Ambient Deposition 

Program at Beaverton Highland Park (41-067-0111). 

6) Started monitoring for TSP lead in McMinnville outside of Cascade Rolling Mills (41-071-1702) on January 

1, 2010 as required by the new lead NAAQS.

LRAPA

7) LRAPA moved their PM2.5 Speciation sampler from Eugene Amazon Park (41-039-0060) to Oakridge (41-

039-2013) on July 1, 2009.

8) LRAPA ran a one year Nephelometer study in Florence (on the coast) ending in Oct, 2009.

9) LRAPA temporarily halted air toxic sampling at Eugene Amazon Park in July 2009 to save resources for a 

two site Eugene air toxic network. The two site network started in April, 2010 at Amazon Park 41-039-

0060 and Eugene Petersen Park (41-039-0101). 

10) LRAPA started submitting Eugene, Wilkes Drive Meteorology data to DEQ and EPA.

4 Status of the Current Ambient Air Monitoring Network 

Section 4 contains the current listing of Oregon's SLAMS/NCORE network for: PM10, PM2.5, PM2.5 chemical 

speciation, Continuous PM2.5 Estimates, SO2, NO2, CO, O3, Lead, Air toxics, Visibility, Forest Health, Field 

Burning, and Meteorology.

4.1 Particulate Matter (PM10, EPA pollutant #81102)

Oregon had many non-attainment areas for PM10 but the PM10 levels have trended down dramatically since these 

designations were made and SIP and maintenance programs were put in place. Figures 1and 2 show the PM10

trends.

Trends

Oregon has at least two cities (Oakridge and Klamath Falls) that currently violate the new PM2.5 daily standard 

of the three year average 98th percentile of 35ug/m3. There is one additional city (Lakeview) whose 2007-2009

98th Percentile was above the standard. There are also numerous cities in Oregon that are areas of concern with 

three year average 98th percentiles above 25ug/m3. Figure 4 shows these cities and all average 98th percentile 

for 2007-2009. 

Figure 4. Average 98th percentile PM2.5 for 2007-2009 for Oregon cities.

Network:

Oregon meets the SLAMS/NCORE requirements in 40 CFR Part 58, Appendix D (2.8 & 3.7). Table 2 and 

Figure 5 show the Oregon’s PM2.5 Federal Reference Method sampler network used for NAAQS compliance. 

These are filter based samplers and are not used to calculate the AQI. Tables 3 lists the PM2.5 estimate network 

used to calculate the AQI. 

Note: The FRM samplers are collocated with the visibility monitors (nephelometers) to provide 

correlation equations. These equations are used to convert visibility into to PM2.5 estimates.

4.2.1 PM2.5 Continuous Network 

The PM2.5 continuous network is comprised of RadianceTM nephelometers. All Federal Reference Method PM2.5

filter samplers are co-located with nephs. The nephelometers are correlated to the filter samplers and provide 

real time data resolved to as low as one second intervals. The PM2.5 calculated from the nephelometers is 

estimated and is used for informational purposes and not for official comparison to the NAAQS. Table 3 and 

Figure 6 show the continuous PM2.5 network used for the AQI.

4.2.2 PM2.5 Speciation 

PM2.5 can be comprised of metal, carbonaceous material, aerosols, or other compounds. Speciation helps identify 

the type of particulate so ODEQ staff can better understand its emission source. ODEQ is operating PM2.5

Speciation samplers at four cities listed in Table 4 and shown in Figure 7.

EPA lists 188 Hazardous Air Pollutants (HAPS) or air toxics in the Clean Air Act Amendments of 1990. Of these 

EPA identifies 33 urban HAPS which it considers to pose the greatest risk to public health in urban areas. EPA 

Urban HAPS list is discussed at http://www.epa.gov/ttn/atw/urban/list33.html. ODEQ revised this list to include 

20 HAPS of concern in Oregon, shown in Table 11.

Currently ODEQ analyzes for the compounds in Table 11 except Acrolein and diesel particulate. No method is 

available to accurately measure Acrolein or diesel PM. ODEQ does monitor for black carbon at two sites using an 

Aethalometer. Black carbon is a component of diesel particulate and can be used as a surrogate. ODEQ analyzes 

for 104 compounds in the HAPS program, a complete list is available in Appendix A.

Network

DEQ currently operates air toxic sites in Portland, Salem, Medford, and La Grande. LRAPA operates two sites in 

Eugene. The sites are listed in Table 12 and shown in Figure 12.

4.9 Air Quality Index (Real Time Networks)

ODEQ converts all our Ozone, CO, and PM estimates to real time health information using EPA’s Air Quality 

Index (AQI). This is a nationwide index that normalizes these pollutants and is used to inform the public about 

current healthy air levels. Figure 13 shows a part of ODEQ’s AQI web page, updated hourly. Figure 14 shows all 

the locations where AQI is available. ODEQ also sends this data to EPA’s AQI page, AIRNow 

http://www.airnow.gov/, on an hourly basis. LRAPA manages their own AQI web page and AIRNow upload. 

ODEQ also provides all hourly and five minute continuous data to Washington State University for their 

AIRPACT pollution model, University of Washington for their MM-5 meteorology model, and Portland State 

University’s Environmental School.

4.10 Field Burning Network

ODEQ partners with the Oregon Department of Agriculture to monitor Willamette Valley field burning from July 

through September. The sites are shown in Table 13. The field burning network consists of visibility monitors 

(nephelometers) and meteorology. This information is used to track the effectiveness of the Department of 

Agriculture’s field burning control program. The visibility data is converted to PM2.5 estimates and is available 

once per hour on ODEQ’s web site and uploaded to AIRNow.

ODEQ is also partnering with Union County to operate a field burning site in the Grande Ronde Valley in Cove. 

The Cove site provides visibility, PM2.5 estimates, and wind speed and wind direction.

ODEQ partners with the US Forest Service and BLM to monitor prescribed burning and forest fires in the areas 

shown in Table 14. The forest health network consists of visibility monitors (nephelometers). This information is 

used to track the effectiveness of the USFS/BLM prescribed burning program and health impacts from forest fire 

smoke. The visibility data is converted to PM2.5 estimates and is available once per hour on ODEQ’s web site and 

AIRNow.

Wildfire Air Quality Rating (WAQR)

ODEQ created a rating (index) which uses PM2.5 estimates to calculate health levels. The health level rating is 

updated hourly and includes the maximum one, eight, or 24 hour average. The one hour average is important 

because a forest fire smoke plume is concentrated and can inundate an area within an hour. EPA’s Air Quality 

Index health levels are based on 24 hour averages and do not register immediate smoke inundation. Figure 15

shows the WAQR web page.

Figure 15. Wildfire Air Quality Rating (WAQR) web page.

4.12 Visibility Network

ODEQ operates a four site visibility network near pristine Class 1 areas; three in the Cascade Range and one near 

the Eagle Cap Wilderness in NE Oregon. Table 15 lists the visibility sites.

These sites operate both visibility and meteorology sensors and the data is available in the AQI or WAQR on an 

hourly basis.

EPA operates its own visibility network (IMPROVE) which speciates PM2.5 in pristine areas. These sites are listed 

in Table 16 and shown in Figure 16. The National Atmospheric Deposition Program is a consortium of agencies 

that monitor for pollutant deposition. There are six NADP sites in or next to Oregon also shown in Figure 16. 

NADP consists of the Mercury Deposition Network (MDN) and the National Trends Network (NTN). More 

information is available at http://nadp.sws.uiuc.edu/.

2010 Oregon Annual Ambient Air Monitoring Network Plan

5 July 2010 to June 2011 Network Plan 

Recently, EPA has revised the NO2 standard and monitoring rule, requiring one to two new 

monitors in Oregon. EPA has proposed revising the Ozone NAAQS and monitoring rule 

with the possible addition of one to two monitors. EPA proposed revising the SO2 NAAQS 

and monitoring rule with the possibility of adding two to three new monitors. EPA 

proposed revising the lead rule with the possibility of adding one to two new monitors. Still 

to come in 2010, EPA will propose a revised PM2.5 NAAQS which may require more 

investment in monitoring.

At the same time as these new monitoring requirements go into effect, Oregon is facing a 

state budget cut. Due to reduced revenue projections, ODEQ is required to submit a budget 

proposal of 9% across the board cuts of the state general fund for the 2011-2013 Biennium. 

If fully taken, these budget cuts will result in the closure of numerous sites and the reduction 

of monitoring staff positions and these resources will not be available to meet any of the 

new EPA monitoring requirements. Shutting down the some PM10, CO, Continuous PM2.5, 

and air toxics sites will help meet these reductions while maintaining the current ozone and 

PM2.5 networks.

ODEQ plans on the following network changes to cut costs and refocus resources from low 

priority to high priority monitoring. ODEQ will:

PM10

1) Discontinue the Grants Pass (41-033-0114) PM10 FRM. This site has not had an 

annual second high value above 33% of the NAAQS in the last 10 years. The 

funding will be transferred to PM2.5 in Prineville or lost to state budget cuts.

2) Discontinue the Pendleton PM10 FRM (41-059-0121). This site has not had an 

annual second high value above 37% of the NAAQS in the last 10 years. The 

funding will be transferred to either 1) support new ozone, SO2, or NO2 monitoring 

requirement or 2) be lost in possible state budget cuts.

3) Discontinue the Medford Welch and Jackson PM10 FRM (41-029-2129). This site 

has not had an annual second high value above 62% of the NAAQS in the last 10 

years. The funding will be transferred to either 1) support new ozone, SO2, or NO2

monitoring requirement or 2) be lost in possible state budget cuts.

[This monitor is one of three in the Medford PM10 AQMA: The White City PM10

sampler (41-029-4001) will remain operating indefinitely and the Medford Grant 

and Belmont PM10 sampler (41-029-0133) will operate as long as air toxics are 

collected in Medford (possibly for two more years)].

4) Discontinue the Klamath Falls PM10 FRM (41-035-0004). This site has not had a 

second high value above 62% of the NAAQS in the last 10 years. The funding will 

be transferred to either 1) support new ozone, SO2, or NO2 monitoring requirement 

or 2) be lost in possible state budget cuts.

PM2.5

5) Discontinue the La Grande (41-061-0119) PM2.5 FRM. The three year average 98th

percentile for this site is 18ug/m3. The funding will be transferred to the Hillsboro 

site to support the required increase in sampling frequency from every sixth day to 
27 27

27 ever third. LAS will continue to collect light scattering (continuous PM2.5 estimate) 

data.

6) Discontinue the Medford Dodge Road (41-029-1001) PM2.5 FRM Background site. 

The funding will be transferred to support the winter-time PM2.5 monitoring at a new 

site in Silverton.

7) Discontinue the Portland N. Roselawn (41-051-0246) PM2.5 FRM. The PNR three 

year average 98th percentile is 20ug/m3. Funding will be shifted to fund an FRM in 

Sweet Home which was defunded by the Oregon Dept of Agriculture. PNR will 

continue to collect light scattering (continuous PM2.5 estimate) data.

8) Start a Sweet Home (41-43-2002) PM2.5 FRM on a 1/6 schedule. FRM sampling 

will start here because the site had an estimated three year average 98th percentile of 

32ug/m3(based on light scattering). 

9) Hillsboro (41-067-0004) PM2.5 FRM will change its schedule from 1/6 to 1/3 

because its current 98th percentile is within 5 to10% of the NAAQS.

10) ODEQ will start up a light scattering (continuous PM2.5 estimate) and meteorology 

site in Silverton, Oregon which will be funded during the summer months by the 

Oregon Department of Agriculture and during the winter by DEQ. The site will 

monitor field burning in the area just northwest of Salem starting July, 2010.

11) ODEQ may discontinue light scattering(continuous PM2.5 estimate) at the Klamath 

Falls Background site to transfer funding to either 1) support for a PM2.5 survey in 

the Klamath Falls area to validate modeling results or 2) be lost in possible state 

budget cuts.

12) Will assist the Siletz Tribe in the set up and operation of a Coos Bay light scattering 

(continuous PM2.5 estimate) and meteorology site if requested. Offer remains open.

CO

13) Discontinue the Portland, SW 3rd CO site (41-051-0087). This site is 21% of the 

NAAQS. The funding will be transferred to either 1) support new ozone, SO2, or 

NO2 monitoring requirement or 2) be lost in possible state budget cuts.

14) Discontinue the Medford Rogue Valley Mall CO site (41-039-0018). This site is 

25% of the NAAQS. The funding will be transferred to either 1) support new 

ozone, SO2, or NO2 monitoring requirement or 2) be lost in possible state budget 

cuts.

Lead

15) ODEQ will start an NCORE TSP (or PM10) lead monitor at Portland SE Lafayette 

(41-051-0080) in Jan. 2011. The funding source is expected to be EPA, as they have 

done with the new Pb is in McMinnville.

16) ODEQ will start a TSP lead site at the Hillsboro Airport (no site yet) in Jan 2011 

pending final adoption of the revised rule of 0.5tpy lead per source. The funding 

source is also expected to be EPA.

NOy

17) ODEQ will start operating an NOy monitor at Portland SE Lafayette (41-051-0080) 

in Jan. 2011 as required by NCORE. This will be funded by the federal PM2.5 grant.

Air Toxics

18) ODEQ will move the Salem air toxics site on July 1st to Hillsboro, N. Portland, 

Gresham, Albany, McMinnville, or St. Helens depending on the outcome of the 

2005 NATA yet to be reviewed. The state funding for this site may be cut on June 

30th, 2011 at which time the site may be discontinued.

2010 Oregon Annual Ambient Air Monitoring Network Plan

With these network changes Oregon DEQ and LRAPA will continue to provide useful high 28

quality monitoring information to Oregonians and to EPA. 

6 Conclusion

In general ODEQ and LRAPA are continuing to follow the EPA monitoring strategic plan 

and focus our networks on PM2.5 and ozone (because these pollutants are near or above the 

NAAQS), air toxics, and real time reporting. We also have Oregon’s National CORE site 

at Portland, SE Lafayette fully operational except for NOy which we will do before January 

2011.

Recent (and proposed) changes in the NAAQS and monitoring rules will require DEQ to 

focus more resources on ozone, NO2 and SO2. We will also likely have to add more PM2.5

and lead sites. All these new requirements are occurring while Oregon state funding is 

being cut. To finance this new monitoring, some lower priority monitoring will need to be 

discontinued. Carbon monoxide and PM10 have remained far below the NAAQS for at least 

ten years. ODEQ will shut down our remaining non trace CO sites and four of our PM10

sites.
