Section 1. Purposes, scope, and organization of report

In California, there are more than 250 locations where ambient air quality is 

routinely measured for gaseous and particulate air pollutants. The measured 

data form a backbone for air quality management programs, provide the public 

with information on current conditions and the progress in improving air quality, 

and are used by health researchers, business interests, environmental groups, 

and others.

This report describes the network of ambient air quality monitors in parts of

California. The report meets requirements for an annual network plan as listed in 

Title 40, Part 58, Section 10 of the Code of Federal Regulations (40 CFR 58.10). 

The language of 40 CFR 58.10 is included in Appendix A. The regulations 

require that the report be submitted to the U.S. Environmental Protection Agency 

(U.S. EPA) in July of each year.

Fourteen local air agencies in California that operate monitoring sites are 

reporting separately on the ambient monitoring within their jurisdictions. The 

geographical scope of this report consists of 25 counties or portions of counties 

with ambient monitoring sites for which the local air agencies are not drafting a 

separate report. Table 1 lists the local agencies that are drafting their own 

reports and those whose monitoring is included in this report. Figure 1 shows the 

areas covered by this report and the locations of the included monitoring sites. 

Table 2 lists the elements required in 40 CFR 58.10 to be in the network plan. 

Also listed in Table 2 is the location(s) within the report that provides information 

on each required element. Table 3 in Section 3 of the report lists each of the 

monitoring sites covered in this report together with its purpose. Table 4 in 

Section 4 of the report lists additional information about the same monitors, such 

as monitoring objective and spatial scale information. Table 5 in Section 5 of the 

report lists the numbers of required and existing monitoring sites by metropolitan 

statistical areas (MSA) that are covered in the geographical scope of this report. 

Table 6 in Section 5 lists the number of required and existing monitoring sites by 

Core-Based Statistical Area (CBSA) for SO2. Table 7 and Table 8 in Section 6 

list the number of required and existing collocation sites for PM2.5 and PM10. 

Table 9 in Section 7 of the report lists the current operating schedules of the 

PM2.5 monitors at PM2.5 monitoring sites that are covered in this report.

While this report covers monitoring in limited parts of California, the California Air 

Resources Board (ARB) produces other publicly available information on air 

quality monitoring throughout all of California. Section 10 of this report lists 

references and web links to this information.

As required by the regulations, this report includes monitors which are federal 

reference methods (FRM) or federal equivalent methods (FEM) and operated by 

air agencies. While the CFR also requires reporting of approved regional 

methods (ARM), no ARMs are in operation in California at this time, and there 
_______________________________________________________________________

2 2011 Annual Monitoring Network Report for Small Districts in California

are no plans to operate monitors of this type in California. The terms FRM and 

FEM denote monitoring instruments that are permitted by federal regulation to 

measure concentrations of pollutants for comparison to the ambient air quality 

standards. An ARM is a state- or locally-approved device that serves the same 

purpose.

In compiling this report, ARB solicited input from and review by the local air 

districts whose jurisdictions are included. Also, the report was available for a 

30 day public inspection period prior to its submittal to the U.S. EPA.

This report can be downloaded from the internet at

Section 2. General information about the monitoring network

California’s ambient air monitoring network is one of the most extensive in the 

world, consisting of over 250 sites where air pollution levels are monitored and 

more than 700 monitors used to measure the pollutant levels. The monitoring 

network needs to be large to cover the diverse range of topography, 

meteorology, emissions, and air quality in California, while adequately 

representing a large population. The monitoring network is critical in assessing 

the State’s clean air progress and in determining pollutant exposures in 

California. 

The network of monitoring sites for a pollutant tends to be denser where the air 

quality problem is worse and where the population is greater. The monitoring 

network also strives to provide representative data to all the broad geographical 

areas in California, including the coastal areas, the interior valleys, the desert 

regions, and the mountainous areas. Monitoring is also conducted in Mexico, 

across the border from San Diego and Imperial counties. Monitors are operated 

by ARB, some by local air districts, and a few by other entities including the 

National Park Service, private contractors, and tribal authorities.

Ambient concentration data are collected for a wide variety of pollutants. The 

most important of these are ozone (O3), particulate matter with diameter 2.5 

microns or less (PM2.5), particulate matter with diameter 10 microns or less 

(PM10), and a number of toxic compounds. Monitoring for meteorological 

parameters is also conducted at a number of sites. The data is needed to better 

understand and inform the public about the nature of the ambient air quality 

problems in California. 

Not all pollutants are monitored at all sites. Most sites monitor for multiple 

pollutants; other sites monitor for only one or two. The State and local air quality 

agencies in California make the effort to only collect data that is needed from 

each site. The needs for the monitoring data are varied. A sense of this can be 

gathered from the information on monitoring purposes in the next section of this

report.

A fundamental purpose of monitoring is to distinguish between areas where 

pollutant levels exceed the ambient air quality standards and areas where they 

do not. Health-based ambient air quality standards are set at levels of pollutant 

concentrations that result in adverse impacts to human health. Evidence of a 

standard being exceeded in an area leads to efforts to reduce the sources of 

pollution that result in the exceedances. In other words, air quality agencies 

develop strategies and regulations to achieve needed emission reductions. Data 

from the ambient monitoring network are then used to indicate the success of 

this, in terms of the rate of progress towards attaining the standards or to show 

that standards have been attained. Section 10 of this report includes references 

to more information on California monitoring networks.
_______________________________________________________________________

Section 3. Purposes served by the monitors

The data from a network of air quality monitors serves many purposes that 

benefit a number of groups of society in different ways. The data are useful to 

health researchers, the general public, regulatory agency staff, 

environmentalists, business interests, and others. For example, the 

measurements of pollutant concentrations that come from the air quality monitors 

in the network are used: to determine compliance with ambient air quality 

standards; as the basis of daily reports to the public in newspapers and on TV; 

and in determining the levels of pollution above which there are significant 

adverse health effects. Each monitor in the network serves at least one purpose 

and most of the monitors serve multiple purposes.

By their nature, some of the purposes are met by a limited number of monitors, 

e.g., the purpose of monitoring for the highest concentrations of a pollutant in an 

area. Other purposes are general in nature, e.g., most monitors are useful for 

public reporting of the ambient air quality in the vicinity of the monitor and for 

providing spatial representation of air quality in the sub-regions of a larger region. 

And yet other purposes are quite specific, such as for a special study on health 

consequences or for modeling an episode of particularly bad air quality.

Some purposes may, in one context, apply to almost all monitoring for a pollutant 

and in another context more selectively apply to a small subset of the monitors. 

For example, the purpose of determining compliance with the ambient air quality 

standards applies to a subset of monitors. The State uses monitoring data to

determine if an area is in attainment or non-attainment of the State air quality 

standards. In this process of determining “State designations”, the data from all 

monitors in an area can be looked at but only the data from a small number of 

monitors with the highest concentrations will drive the determination of the 

designation for the area. Therefore, a smaller number of monitors are given the 

“State designation” purpose.

The next section includes a short description of monitoring purposes. After that, 

Table 3 lists the purposes served by each monitor included in the scope of this 

report, and for which official data for 2010 was reported. Table 3 uses codes to 

identify the primary purpose of each monitor and the definitions are provided at 

the end of the table. Note that although the category “general purposes” applies

to most of the monitors; however, the code for “general purposes” only appears if 

this is the most important purpose for the monitor. Also, no effort was made to 

indicate whether any monitors are serving ad hoc purposes at this time. Such 

conditions can change quickly.

Table 4 in Section 4 of this report lists the monitoring objectives of the monitors, 

which is different than how the term monitoring purposes is used in this report. 

The CFR requires that the monitoring objectives be listed in this annual network 

report. These monitoring objectives are the federal monitoring objectives as 
_______________________________________________________________________

7 2011 Annual Monitoring Network Report for Small Districts in California

defined by the U.S. EPA. These do not include a number of additional State and 

local monitoring objectives. This section of the report lists the broader purposes 

served by the monitors, including the State, local, and federal purposes for 

monitoring. The federal monitoring objectives are a subset of this broader list of 

monitoring purposes.

Also listed in Table 3 are the locations of the monitors, including the metropolitan 

and micropolitan statistical areas in which the monitors are located. Certain 

requirements in 40 CFR 58 are based on metropolitan statistical areas (MSAs). 

MSAs are part of a classification of geographical regions developed by the U.S. 

Office of Management and Budget (OMB). An MSA may include one or more 

counties. However, not all counties are within an MSA. In Table 3, the 

appropriate metropolitan or micropolitan statistical area is listed after the county 

name.

Summary of Monitoring Purposes

Agricultural Burning refers to the intentional use of fire for vegetation 

management, both in agricultural settings, such as fields and orchards, as well as 

in wildlands, including rangeland and forests, to improve land for wildlife and 

game habitat or as a tool for disease or pest prevention. Monitors with this 

purpose are used to assess when and where burning can occur.

Background Level monitoring is used to determine general background levels of 

air pollutants. Background concentrations vary between different air pollutants.

Expected High Concentration monitoring is used to measure pollutant 

concentrations in areas where air pollution is expected to be at its highest. The 

State designation criteria contain the requirement for this type of monitoring in 

order to show that an area attains the State air quality standards. During the 

State area designation process, the data from all monitors in an area are

examined, but only the data from the monitors with the highest concentrations 

will determine the designation of the area.

The Geyser Air Monitoring Program (GAMP) was established to monitor ambient 

air quality in geothermal areas, mainly monitoring for hydrogen sulfide. 

High Concentration monitoring is done at sites to determine the highest 

concentration of an air pollutant in an area within the monitoring network. A 

monitoring network may have multiple high concentration sites, due, for example,

to varying meteorology year to year. This is a purpose listed by the U.S. EPA.

Pollutant Transport is the movement of pollutants between air basins or regions. 

Data from monitors with this purpose are used to assess and determine 

appropriate mitigation strategies for pollution in upwind areas which affects 

neighboring downwind areas. Also, data from these monitors are used to 
_______________________________________________________________________

8 2011 Annual Monitoring Network Report for Small Districts in California

determine the extent of regional pollutant transport among populated areas to 

agricultural and wildland areas.

Population Exposure monitoring is done to represent the air pollutant 

concentrations a populated area is exposed to.

Public Reporting means providing air quality data to the general public in a timely 

manner. Data can be presented in a number of ways including newspapers and 

TV, internet web pages, air quality maps, and hardcopies.

Residential Burning or backyard burning is the open burning of yard wastes by 

household residents. Backyard burning includes dry weeds, plant pruning, 

shrubbery, tree trimmings, and branches. Data from monitors with this purpose 

help guide decisions regarding appropriate times to allow residential burning.

Representative Concentration means locating a site to represent a geographical 

region with common topography and meteorology. These sites do not 

necessarily indicate the highest concentrations in the area for a particular 

pollutant.

Source Impact monitoring is used to determine the impact of significant sources 

or source categories of air quality emissions on ambient air quality. The air 

pollutant sources may be stationary or mobile. 

State Area Designation monitoring is used to determine compliance with the 

State ambient air quality standards for a particular pollutant. Using the monitors 

with the highest concentrations of a particular pollutant, the ARB determines if 

the area is in attainment or non-attainment of the State air quality standards, as 

already described in the discussion of Expected High Concentration Monitoring.

State Implementation Plan (SIP) and/or Maintenance Plan Requirement is 

monitoring conducted to demonstrate compliance with SIP requirements. The 

SIP is a plan prepared by states and submitted to the U.S. EPA describing how 

each area will attain and maintain federal air quality standards. Once an area 

attains a standard, the area is required to show and maintain that status, which 

requires continued monitoring in the area. 

Trend Analysis monitoring is useful for comparing and analyzing air pollution 

concentrations over time and distance. Usually, trend analyses show the 

progress or lack of progress in improving air quality for an area over a period of 

years. Some sites are more useful than others for trend analyses. For example, 

it is better to have a history of monitoring at a site that includes the full time 

period of a trend analysis.

Welfare Effects monitoring is use to measure air pollution impacts on visibility, 

vegetation damage, or other welfare-based impacts.

Footnotes:

This table only lists sites and monitors that have reported data in 2010 or sites and monitors that 

were listed on the returned survey questionnaire from the air districts that are covered in this 

report.

Lead monitors are not included in this list because there is no lead monitoring in these areas.

* CONT, CONT-FEM, or SPEC in a PM column denotes that a continuous (CONT) PM or 

speciation (SPEC) PM monitor is located at the site.

CONT-FEM stands for a continuous federal equivalent method. Continuous PM montioring 

provides realtime hourly concentration values. 

This is useful for public reporting, better understanding of episodes of high PM concentrations, 

identification of sources of pollutants, possible allowance for less frequent filter sampling, etc. 

Monitoring purposes for continuous PM monitors are not listed.

** After a county name, the table lists the U.S. Office of Management and Budget's metropolitan 

(MSA) or micropolitan statistical area that includes the county.

*** Monitors for which the data were not being submitted to ARB or EPA in 2010. 

^ The ARB established continuous PM2.5 and PM10 FEM monitors at this site in March 2011. 

The Eastern Kern APCD plans to discontinue the PM10 FRM monitor on June 30, 2011 and the 

PM2.5 FRM monitor on March 31, 2012. 

^^ The PM2.5 filter-based monitor was discontinued in July 2010. A continuous PM2.5 FEM 

monitor replaced the filter-based monitor at this site.

^^^ The continuous PM2.5 BAM monitor at this site is not reporting data to EPA's AQS database

Section 4. Additional information about the monitors 

U.S. EPA regulations require that the annual network plan list specific additional 

information about the monitors that characterizes the nature and location of the 

monitoring. Table 4 lists the monitoring objectives, spatial scales, and sampling 

methods of the monitors that are covered in this report. Also included in Table 4 

are the geographical coordinates of the monitoring sites.

The regulations also require that the annual network plan list the laboratory 

analysis methods of the monitors. However, there is no separate analysis 

method for the gaseous monitors and continuous PM monitors. Also, for the 

filter-based PM monitors, only simple mass weighing is done.

As already pointed out in Section 3, the monitoring objectives listed below in 

Table 4 are not the same as the monitoring purposes listed in Table 3 in 

Section 3. The monitoring objectives used for Table 4 are the federal monitoring 

objectives as defined by the U.S. EPA. At the end of Table 4, the codes used for

the monitoring objectives, spatial scales, and sampling methods are defined.

Federal monitoring objectives
_______________________________________________________________________

18 2011 Annual Monitoring Network Report for Small Districts in California

Section 5. Monitoring required by the U.S. EPA

U.S. EPA regulations specify the minimum number of sites at which state and 

local air agencies must deploy monitors. In California, State and local agencies 

find they need to deploy significantly more monitors. The additional monitors are 

needed to fulfill State and local purposes for monitoring that are in addition to the 

federal purposes. For example, because State air quality standards tend to be 

more stringent than national standards, some areas may need more monitors 

than those needed to show compliance with the national standards. Further, the 

public expects to be informed of the actual air quality conditions where they live 

and work. While this objective is not explicitly built into the federal regulatory 

requirements, State and local air agencies in California attempt to be responsive 

to public expectations.

Requirements for the minimum numbers of monitors appear in Appendix D of 

Part 58 of the CFR. For ozone, PM2.5, and PM10, the required minimum number 

is based on the population of an area and the severity of the air quality for the 

pollutant in the area. For purposes of the minimum requirements, the areas are 

defined by the MSAs developed by the OMB (more information on MSAs 

appears on page 7). Note that elsewhere in the CFR there are requirements for 

monitoring to indicate whether an area designated as attaining an air quality 

standard is maintaining the attainment status. This annual network plan is not 

required to address maintenance plan requirements, however, monitoring

information on State and Local Air Monitoring Stations (SLAMS) and Special 

Purpose Monitoring (SPM) sites are included in other parts of this plan.

For the parts of the State included in this report, Table 5 lists information on the 

number of existing O3, PM2.5, and PM10 monitors and the number required by 

Appendix D. In all cases, sufficient monitoring exists. The information is listed 

by MSA. The number of required monitors is based on the population of the 

MSA, taken from the 2010 U.S. Census, in combination with the degree to which 

air quality in the MSA is greater or less than the national air quality standards.

Notes:

2007-2009 air quality data was used in determining the number of required sites.

the geographical scope of the reports being completed

by the districts. The numbers of sites listed are for the entire MSA.

1 FRM: Federal Reference Method

2 Cont.: Refers to a continuous PM2.5 monitor, i.e., one that measures hourly data. 3 SSI: Size Selective Inlet. The SSI is an FRM for PM10.

Monitoring for carbon monoxide (CO) and nitrogen dioxide (NO2) is not currently 

required anywhere in California in order to comply with the Appendix D 

requirements of 40 CFR 58. Ambient concentrations for these pollutants do not 

exceed the national air quality standards and do not trigger these requirements 

for monitoring. As required by a different part of 40 CFR 58 that takes effect in 

2013, new NO2 roadside monitoring in many of California’s urban areas will be 

required. These new near-road monitors will be addressed in the 2012 network 

report. Even without federal requirements, dozens of sites in California have 

monitored for CO and NO2 for a number of years.

On June 22, 2010, the U.S. EPA published the final rule for the revised federal

SO2 standard which specifies the minimum number of sites at which state and 

local air agencies must deploy SO2 monitors. The monitoring regulations require 

SO2 monitors be placed in Core Based Statistical Areas (CBSAs) based on a 

population weighted emissions index (PWEI) for the area. The PWEI of a CBSA 
_______________________________________________________________________

20 2011 Annual Monitoring Network Report for Small Districts in California

is calculated by multiplying the latest available SO2 emission data within each 

CBSA by the population of the CBSA and then divided by one million. The final 

rule requires:

• Three SO2 monitors in CBSAs with PWEI values of one million or more;

• Two SO2 monitors in CBSAs with PWEI values less than one million 

but greater than 100,000; and

• One SO2 monitor in CBSAs with PWEI values greater than 5,000 but 

less than 100,000.

California has thirty-five CBSAs with population ranging from 17,000 to more 

than 12 million people. Table 6 lists the CBSAs in California that require SO2

monitoring. In addition, Table 6 shows that these CBSAs exceed federal 

monitoring requirements for SO2. California’s monitoring network currently 

consists of 39 SO2 monitors, in excess of the 4 required monitors.

Table 6

Minimum Monitoring Requirements for SO2

(By CBSA and PWEI)

On December 14, 2010, the U.S. EPA finalized the rule for the revised federal 

lead (Pb) standard, which also specifies the monitoring requirements for Pb. 

While the final rule maintains the airport monitoring threshold at 1.0 ton per year

(tpy), the rule lowers the industrial source-oriented monitoring threshold from 1.0 

tpy to 0.5 tpy. In addition, the final rule replaces the population-based monitoring 

requirement with a requirement to monitor for Pb at urban NCore sites.

The U.S EPA selected 15 airports for a one-year study as part of the new Pb 

rule. Five airports are in California: Palo Alto Airport, McClellan-Palomar Airport, 

Reid-Hillview Airport, Gillespie Field Airport, and San Carlos Airport. None of 

these airports are in the geographical scope of this report.

In regards to source-oriented monitoring for Pb, the only stationary source in 

California meeting the 1.0 tpy threshold is located in the South Coast Air Basin. 

Refer to the South Coast annual network plan for a description of their sourceoriented lead monitors. The areas covered in this network plan will not be 

required to conduct source-oriented lead monitoring.

Lastly, the final rule requires Pb monitoring at urban NCore sites. Urban NCore 

is defined as those sites in a Core-Based Statistical Area (CBSA) of 500,000 or 

more. Currently, there are six NCore sites in California and they are located in 

Sacramento, San Jose, Fresno, Los Angeles, Riverside, and El Cajon. None of 

the NCore sites are located in areas covered by this network plan.

22 2011 Annual Monitoring Network Report for Small Districts in California

Section 6. Required quality assurance of the monitoring program

The information below, along with the information available via the web link,

describes the status of compliance with the requirements of 40 CFR 58,

Appendices A, C, and E. The annual network plan is required to include such 

information. 

Annually, the Quality Assurance Section (QAS) of ARB conducts performance 

evaluations (audits) for each SO2, NO2, O3, and CO analyzer with National 

Institute of Standards and Technology (NIST) traceable gases. Each analyzer is 

audited at three levels using known concentrations of gases. Annual PM monitor 

flow rate audits are conducted with a BGI (Bob Gussman Incorporated) variable 

orifice mass flow meter, or TetraCal, which is certified against NIST traceable 

primary standards. Semi-annual flow rate audits for PM monitors are required. 

Currently, QAS conducts one annual PM flow rate audit and a U.S. EPA 

Region 9 contractor conducts the second PM flow rate audit to fulfill CFR

requirements. Beginning in 2012, QAS will not be extending its contract with the 

Region 9 contractor and will be conducting both flow rate audits for the PM 

monitors.

Laboratory audits for the toxics program are conducted using certified gases 

and/or materials. Meteorological audits are conducted with instruments that are 

NIST traceable and/or manufacturer-certified. All of the audits performed by 

QAS are conducted in accordance with the 40 CFR 58, Appendix A. 

As part of the annual audit at each air monitoring station, QAS conducts siting 

evaluations. Physical measurements and observations, including probe/sensor 

height above ground level, distance from trees, type of ground cover, residence 

time, obstructions to air flow, and distance to local sources, topography, vehicle 

counts, predominant wind direction, probe material, etc., are taken to determine 

compliance with 40 CFR Part 58, Appendix E requirements. 

QAS also ensures the quality of the data collected by the air monitoring sites 

operating in California through analysis of precision data submitted to the 

U.S. EPA’s ambient air quality database, the Air Quality System (AQS). 

Precision checks for gaseous/continuous samplers are performed once every 

two weeks. Precision checks for non-continuous, collocated particulate samplers 

are done at least every twelfth day. QAS staff analyzes the precision data in 

accordance with 40 CFR 58, Appendix A.

In addition, air monitoring staff performs a one-point flow rate verification check 

once every month on high-volume PM10 and PM2.5 monitors and twice a month 

on BAM10 and BAM2.5 automated analyzers. Air monitoring staff reviews these 

data and takes corrective action when the results exceed U.S. EPA’s 

requirements. Currently, the percent difference between the flow rate of the 

transfer standard and corresponding flow rate measured by the analyzer are
_______________________________________________________________________

23 2011 Annual Monitoring Network Report for Small Districts in California

not used to assess the bias of the monitoring data in accordance with 40 CFR 

Part 58, Appendix A, 3.2.3. Staff is in the process of incorporating these data to 

measure bias and meet Appendix A requirements.

QAS also conducts system audits to determine if a district’s air monitoring 

program satisfies the requirements of 40 CFR Part 58 and U.S. EPA's Quality 

Assurance Handbook for Air Pollution Measurement Systems, Volume II, 

December 2008. Compliance with these regulations is necessary if the data are 

to be considered data-for-record per the California Code of Regulations (Title 17, 

Article 3, section 70301). Data meeting these requirements are eligible to be 

used in actions taken pursuant to the Federal Clean Air Act and the California 

Clean Air Act.

Information about each air monitoring station audited by QAS is available at:

http://www.arb.ca.gov/qaweb/site.php. This web page includes maps of each 

site, latitude and longitude coordinates as determined by GPS, site photos, 

precision and accuracy data, and a detailed site survey of the physical 

parameters and conditions at each site. This web page also includes an area for 

district precision and accuracy reports. Also, as required by Appendix A of 40 

CFR 58, quarterly measurement checks are directly submitted to AQS by QAS 

staff. In addition, as required by 40 CFR 58.15, the ARB submits a data 

certification letter along with the required AQS reports (AMP255 and AMP450) to 

U.S. EPA, annually.

The most recent (i.e., 2010 or 2011) conducted surveys of the sites covered in 

the geographical scope of this report can be found in Appendix B of this report. 

In addition, detailed monitor information, such as distances between collocated 

monitors, height above ground, and height above platform can also be found in 

this Appendix as well. For example, if collocation monitoring was conducted at 

the site, then the distance between collocated monitors would be recorded in the 

“Sampler Spacing” row of the survey. All measurements listed on the surveys 

are measured in feet. Additional monitor information, such as the begin date of

the monitors covered in this report can be found in Appendix C. Note that 

Appendix B and C of this report only include sites and monitors that are covered 

in this report. A more comprehensive listing of sites and monitors in California 

can be found at: http://www.arb.ca.gov/qaweb/site.php.

6.1 Collocation Requirements

Appendix A of 40 CFR 58 also includes requirements for collocation of samplers 

as part of quality checks for the PM2.5, PM10, and lead (Pb) monitoring networks. 

The CFR contains separate collocation requirements for PM2.5, PM10, and Pb. 

The requirements are to be met for each primary quality assurance organization 

(PQAO). Four PQAOs exist in California, one each for the San Francisco Bay 

Area AQMD, San Diego County APCD, and South Coast AQMD, and one for the 

remainder of the State that is called the ARB PQAO.
_______________________________________________________________________

24 2011 Annual Monitoring Network Report for Small Districts in California

PM2.5 Collocation Status

For PM2.5, the CFR requires that for each PM2.5 federal reference method (FRM) 

monitoring method, 15% of the sites within a PQAO have a collocated monitor of 

the same type. Three types of PM2.5 FRMs exist currently in the ARB PQAO. 

Collocation requirements apply to each type. The types of samplers are: R&P 

Sequential, R&P Non-sequential, and Graseby Andersons. Table 7 shows that 

collocation requirements for PM2.5 FRM are met. 

Table 7

Collocation Requirements for PM2.5 FRM

*The San Joaquin Valley Air Pollution Control District converted the collocated PM2.5 monitors at 

the Bakersfield-California Street site from R&P Sequentials to Graseby Andersons.

The CFR also requires that 15% of the sites with PM2.5 federal equivalent method 

(FEM) monitors be collocated, but that the first collocation monitor be an FRM, 

the second be an FEM, and so on alternating FRM with FEM as additional 

collocation monitors are required. At the time this report was drafted, 21 sites 

have this sampler type in the ARB PQAO. The first collocation requirement must 

be between an FEM/FRM; three sites of this monitoring type currently exist in the 

ARB PQAO. One collocation site between two PM2.5 FEMs is required when 

there are ten or more PM2.5 FEM sites in the ARB PQAO. Currently, the 

Stockton site in the San Joaquin Valley Air Basin is collocated with two 

continuous PM2.5 FEM monitors. For this reason, the collocation requirement for 

this sampler type is met.

California is a very large state in which environmental conditions (e.g., 

temperature, precipitation, humidity, wind speeds, and elevation) vary widely and 

the composition of the PM2.5 varies significantly. Also, a large number of 

operating agencies operate sites in the statewide PM2.5 network. ARB and local 

air districts designed the locations of collocated PM2.5 samplers to strike a 

balance in adequately representing all of these factors. In this way, the quality 

control function of the collocated monitoring is best realized. While Appendix A 

requires 80% of the collocated monitors to be within + 20% of the applicable

federal air quality standard, focusing on achieving this was deemed to result in 

too much clustering of the collocated monitors in too few of the factors needing 

representation.

PM10 Collocation Status

The CFR also requires that 15% of PM10 sites with manual monitoring have 

collocated samplers. However, the CFR language is much less specific as to 

what is required to meet the requirements. A U.S. EPA guidance document 

provides needed clarification. Agencies in the ARB PQAO deploy three types of 

PM10 FRM samplers that require appropriate collocation. All three method types

are filter-based samplers, which either use a volumetric flow controller (VFC) or a 

mass flow controller (MFC). The inlet type and flow rate of the PM10 monitors 

vary among the different PM10 monitoring networks in the ARB PQAO. While 

many of the PM10 monitoring sites in the ARB PQAO use PM10 monitors that 

have high-flow, size-selective inlets (SSI), and VFCs, two monitoring sites in the 

ARB PQAO use PM10 monitors that have low-flow with impactor inlets. Table 8 

shows that two PM10 sampler types met collocation requirements while one 

sampler type requires five additional sites to be collocated. For the VFC/high 

flow/SSI sampler type, the ARB will add collocation samplers to its sites over the 

next year or so, in conjunction with other changes in the PM10 FRM network, so 

that the collocation requirement will be met.

Table 8

Collocation Requirements for PM10 FRM

*The two sites are in the Great Basin Unified Air Pollution Control District, of which the Keeler site 

is collocated.

Lead Collocation Status

On December 14, 2010, the U.S. EPA finalized the rule for the revised federal 

lead (Pb) standard, which also specifies the collocation requirements for Pb. The 

regulations specify that PQAOs that have a combination of source and nonsource Pb sites have 15% of their Pb monitoring sites collocated. The 

regulations also required that the Pb network be treated independently from the 

PM network, and that the first collocation site be at the highest Pb concentration

site within the network. Moreover, the regulations specify that if a PQAO has no 

source or non-source Pb monitoring, and the only Pb monitoring is conducted at 

NCore sites, then the collocated Pb monitor must be of the same method

designation as the primary Pb monitor.

The ARB PQAO requires no source or non-source Pb monitoring. However, the 

ARB PQAO does have two NCore sites which are located at Fresno-1st Street 

and Sacramento-Del Paso Manor. Currently, neither of these sites is collocated 

for Pb. The ARB will establish the collocation for Pb at the Fresno-1st Street site 

in the next year.

Sampler Type # of existing sites # of required sites (15%) # of collocation Req Met?

Section 7. Operating schedules

The CFR requires that the annual network plan include information about 

operating schedules. While gaseous monitors (e.g., O3, CO, NO2, SO2) and 

particulate monitoring with FEMs usually operate continuously and all year, 

particulate monitoring with FRMs often operate one day out of every three days 

or one day out of every six days. The primary reason why particulate FRMs

operate less frequently is that the particulate FRMs are filter-based and therefore

much more labor intensive, requiring that field staff frequently retrieve and 

replace filters and that laboratory staff pre- and post-weigh filters. The 

continuous gaseous and particulate monitors produce hourly measurements of 

the gaseous and particulate pollutants, while the particulate filter-based monitors 

produce 24-hour measurements of particulate pollutants.

Particulate matter operating schedules

Current operating schedules for PM2.5 FRM monitors in the areas included in this 

report are listed in Table 7 below. The current operating schedules of the PM2.5

FRM monitors listed in Table 7 were obtained from the U.S. EPA’s AQS 

database.

While there are a number of continuous PM2.5 monitors deployed, most of these 

are not federal reference or equivalent methods. In March of 2008, the U.S. EPA 

approved the first continuous PM2.5 FEM. In the ARB’s PQAO, there are 21

continuous PM2.5 FEM sites; however, in the areas covered by this report, there 

are only four continuous PM2.5 FEM sites that are currently reporting data into the 

AQS database at this time. The four sites are San Andreas, Ukiah, Willits, and 

Red Bluff. 

Operating schedules for the manual PM10 samplers in the areas included in this 

report operate on a one day in every six day schedule. There are three

continuous PM10 monitors operating in the area that this report covers, which are 

reporting data into AQS. These monitors are located at the South Lake TahoeSandy Way, Fort Bragg, and Mojave sites. The Northern Sonoma County APCD 

is transitioning to continuous PM10 monitoring within its network; however, no 

data are being reported to AQS at this time. Moreover, the continuous PM10

monitor at the Techachapi-Curry site in Kern County is not reporting data to AQS 

at this time as well.

Ozone operating schedules

While most O3 monitors operate continuously all year, a small number of O3 sites 

in the areas included in this volume operate only in the warmer six months of the 

year. Several of these sites are at higher elevation where access during the 

winter can be problematic. Also, for most of the State, O3 is a summertime 

problem and concentrations during the winter are well below the levels of the 

ambient air quality standards. The following seasonal O3 sites in the areas 

included in this report all operate from May through October:

Cool (El Dorado County)

Echo Summit (El Dorado County)

Jerseydale (Mariposa County)

Sutter Buttes (Sutter County)

Tuscan Butte (Tehama County)

Section 8. Additional information on PM2.5 monitors

This section includes information for two required annual network plan elements 

that relate specifically to PM2.5 and do not fit well elsewhere in the report. One 

required element relates to whether data for a PM2.5 monitor can be used to 

determine compliance with the national annual PM2.5 air quality standard. In the 

CFR, this is termed as the suitability for comparison to the annual standard. The 

other element requires including in the annual network plan information regarding 

the review process followed by air agencies when changes are made to the 

location of a PM2.5 monitor that is violating a PM2.5 standard.

8.1 Suitability for comparison to the annual PM2.5 standard

The CFR requires that a PM2.5 FRM or FEM monitor be located at a 

neighborhood scale in order for the data from the monitor to be used in 

regulatory determinations of compliance with the annual PM2.5 standard. For a 

PM2.5 monitor to be representative at a neighborhood scale, the concentration 

values measured by the monitor should be representative of concentrations 

expected over an area with dimensions of a few kilometers. All of the PM2.5 FRM

monitors in California are sited to be representative of a neighborhood scale and 

meet this suitability requirement.

8.2 Review of changes to PM2.5 network

The PM2.5 network of FRM monitors in California was largely established in 1999 

and completed in 2000. Little has changed in the siting of the FRM monitoring 

network between then and now. However, in March of 2008, the U.S. EPA 

approved a continuous monitor as the first type of PM2.5 FEM. A number of 

agencies around the State are now in various stages of purchasing and testdeploying these FEMs. At the time this report was drafted, three agencies (ARB, 

Mendocino County, and Tehama County) in the areas covered by this report

have submitted data from these monitors to the AQS database. While there is 

interagency review of proposed changes to the State and Local Air Monitoring 

Stations (SLAMS) network, i.e., the network that includes PM2.5 as well as O3, 

CO, PM10, and other pollutants, no unique review process exists specially for 

PM2.5 FRM or FEM monitors.

As part of ARB’s ongoing oversight process, ARB requests the opportunity to 

review and comment on the possible regulatory consequences of any proposal to 

move or discontinue a monitor for any pollutant that violates a national or State 

air quality standard. Furthermore, when a local agency proposes to move or 

discontinue a monitor indicating the highest concentrations of a pollutant in an 

area, ARB requests that the agency conduct a period of concurrent monitoring at 

that site and at the replacement site being proposed to represent the area as the 

required high site for the pollutant. This is expected even when the site is close 

to but not exceeding any standard for the pollutant. The concurrent monitoring is 
_______________________________________________________________________

30 2011 Annual Monitoring Network Report for Small Districts in California

typically for a period of many months or a year, depending on the pollutant, the 

standard that is of most concern, and other factors.

The CFR requires that the U.S. EPA review and approve modifications to the 

SLAMS monitoring network, and requires that the responsible state or local 

agency inform the U.S. EPA of any proposed modifications. These requirements 

are in 40 CFR 58.14(b).
_______________________________________________________________________

31 2011 Annual Monitoring Network Report for Small Districts in California

Section 9. Proposed and recently implemented monitoring site changes

This section lists the proposed and recently implemented monitoring site 

changes in the areas included in this report, as well as changes to the monitoring 

sites that the ARB conducts in areas outside the stated geographical scope of 

this report. Proposed monitoring site changes include proposals by the ARB or 

by districts that are covered in this report to add, remove, or move sites and/or 

monitors in the monitoring network before the end of 2012. Recently 

implemented monitoring site changes include deployed sites and monitors in the 

monitoring network that the ARB has become aware of since last year’s report

and for which no official 2010 data were reported. The scope of recently 

implemented monitoring site changes also includes terminated sites and/or 

monitors that the ARB has become aware of since last year’s report.

The ARB discontinued the PM2.5 filter-based monitor at the San Andreas site in 

July 2010 and replaced the filter monitor with a continuous PM2.5 FEM monitor. 

Moreover, the ARB relocated the continuous PM2.5 monitor at the Paradise-Fire 

Station site to a new location, which is located at 6701 Clark Road, Paradise. In 

addition, the ARB plans to relocate the Chico site to a new location, which the 

new site has not officially been established. In coordination with the Eastern 

Kern APCD, the ARB established continuous PM2.5 and PM10 FEM monitors at 

the Mojave-Poole Street site in March 2011. At the time this report was drafted, 

the continuous PM FEM data at the Mojave-Poole Street site has not yet been 

submitted to AQS. As part of two separate special purpose studies, the ARB 

plans to establish two monitoring sites on Catalina Island before the end of 2011 

and established a monitoring site in Weed on August 25, 2010. The monitoring 

sites on Catalina Island will be monitoring for ozone, CO, NO/NO2/NOx, NOy, 

black carbon, sulfate, and meteorological data. The monitoring site in Weed 

monitors for continuous PM2.5 and meteorological data. Lastly, the ARB added 

CO2, methane, and trace level CO monitors at the Sutter Buttes site to monitor

for greenhouse gases (GHG). The ARB also plans to conduct GHG monitoring 

at the Tuscan Buttes site in the next year. 

The Eastern Kern APCD established ozone and continuous PM10 monitoring at 

the Techachapi-Curry site in Kern County. However, the data from these 

monitors are currently not being reported to AQS at the time this report was 

drafted. Moreover, the district plans to discontinue the PM10 FRM monitor and 

the PM2.5 FRM monitor at the Mojave-Poole Street site in June 2011 and March

2012, respectively. The reason for discontinuing the FRM monitors at the 

Mojave-Poole Street site is due to the recent establishment of the continuous PM 

FEM monitors at the site by the ARB.

The Mendocino County AQMD plans to convert the continuous PM10 monitor at 

the Fort Bragg site to a continuous PM2.5 FEM monitor after finding a suitable 

location and having three years of data for State compliance purposes.

The Northern Sierra AQMD started ozone monitoring at the Truckee site in July 

2010.

Section 10. Access to more information about the network

While this report includes a great deal of information about the ambient air quality 

monitoring network, much more information is readily available, including 

summaries of the pollutant data from the monitors around the State. Much of this 

information is available on the web. This section lists a number of additional 

sources of such information. Also listed is contact information for the agencies 

responsible for the monitoring covered in this report.

A broad overview of information about ambient air quality data in general in a 

question and answer format can be found at the following web page: 

http://www.arb.ca.gov/aqd/aqfaq/. This web page includes dozens of links to 

additional technical and non-technical information. 

ARB’s Monitoring and Laboratory Division (MLD) maintains web pages with 

information about all the existing monitoring sites that routinely monitor and 

submit air quality data in California. The pages also include detailed local maps 

showing the location of the sites. This information can be found at: 

http://www.arb.ca.gov/aaqm/mldaqsb/amn.htm. A more general MLD web page 

that provides links to other aspects of ambient monitoring is located at:

http://www.arb.ca.gov/aaqm/aaqm.htm.

In addition to this report, there is another report that contains listings of 

monitoring in the State, along with the years for which data is available for each 

monitor and regional maps showing the locations of the monitoring sites. To 

view this report on the web, go to http://www.arb.ca.gov/aqd/netrpt/netrpt.htm.

APPENDIX A

Regulatory language of 40 CFR 58.10

§ 58.10 Annual monitoring network plan and periodic network 

assessment.

(a)(1) Beginning July 1, 2007, the State, or where applicable local, agency shall 

adopt and submit to the Regional Administrator an annual monitoring network 

plan which shall provide for the establishment and maintenance of an air quality 

surveillance system that consists of a network of SLAMS monitoring stations 

including FRM, FEM, and ARM monitors that are part of SLAMS, NCore stations, 

STN stations, State speciation stations, SPM stations, and/or, in serious, severe 

and extreme O3 nonattainment areas, PAMS stations, and SPM monitoring 

stations. The plan shall include a statement of purposes for each monitor and 

evidence that siting and operation of each monitor meets the requirements of 

appendices A, C, D, and E of this part, where applicable. The annual monitoring 

network plan must be made available for public inspection for at least 30 days 

prior to submission to EPA.

(2) Any annual monitoring network plan that proposes SLAMS network 

modifications including new monitoring sites is subject to the approval of the EPA 

Regional Administrator, who shall provide opportunity for public comment and 

shall approve or disapprove the plan and schedule within 120 days. If the State 

or local agency has already provided a public comment opportunity on its plan 

and has made no changes subsequent to that comment opportunity, and has 

submitted the received comments together with the plan, the Regional 

Administrator is not required to provide a separate opportunity for comment.

(3) The plan for establishing required NCore multipollutant stations shall be 

submitted to the Administrator not later than July 1, 2009. The plan shall provide 

for all required stations to be operational by January 1, 2011.

(4) A plan for establishing Pb monitoring sites in accordance with the 

requirements of appendix D to this part shall be submitted to the EPA Regional 

Administrator no later than July 1, 2009 as part of the annual network plan 

required in paragraph (a)(1) of this section. The plan shall provide for the 

required source-oriented Pb monitoring sites to be operational by January 1, 

2010, and for all required non-source-oriented Pb monitoring sites to be 

operational by January 1, 2011. Specific site locations for the sites to be 

operational by January 1, 2011 are not required as part of the July 1, 2009 

annual network plan, but shall be included in the annual network plan due to be 

submitted to the EPA Regional Administrator on July 1, 2010.
_______________________________________________________________________

38 2011 Annual Monitoring Network Report for Small Districts in California

(b) The annual monitoring network plan must contain the following information for 

each existing and proposed site:

(1) The AQS site identification number.

(2) The location, including street address and geographical coordinates.

(3) The sampling and analysis method(s) for each measured parameter.

(4) The operating schedules for each monitor.

(5) Any proposals to remove or move a monitoring station within a period of 18 

months following plan submittal.

(6) The monitoring objective and spatial scale of representativeness for each 

monitor as defined in appendix D to this part.

(7) The identification of any sites that are suitable and sites that are not suitable 

for comparison against the annual PM2.5 NAAQS as described in §58.30.

(8) The MSA, CBSA, CSA or other area represented by the monitor.

(9) The designation of any Pb monitors as either source-oriented or non-sourceoriented according to Appendix D to 40 CFR part 58.

(10) Any source-oriented monitors for which a waiver has been requested or 

granted by the EPA Regional Administrator as allowed for under paragraph 

4.5(a)(ii) of Appendix D to 40 CFR part 58.

(11) Any source-oriented or non-source-oriented site for which a waiver has been 

requested or granted by the EPA Regional Administrator for the use of Pb-PM10

monitoring in lieu of Pb-TSP monitoring as allowed for under paragraph 2.10 of 

Appendix C to 40 CFR part 58.

(c) The annual monitoring network plan must document how States and local 

agencies provide for the review of changes to a PM2.5monitoring network that 

impact the location of a violating PM2.5 monitor or the creation/change to a 

community monitoring zone, including a description of the proposed use of 

spatial averaging for purposes of making comparisons to the annual PM2.5 -

NAAQS as set forth in appendix N to part 50 of this chapter. The affected State 

or local agency must document the process for obtaining public comment and 

include any comments received through the public notification process within 

their submitted plan.

(d) The State, or where applicable local, agency shall perform and submit to the 

EPA Regional Administrator an assessment of the air quality surveillance system 
_______________________________________________________________________

39 2011 Annual Monitoring Network Report for Small Districts in California

every 5 years to determine, at a minimum, if the network meets the monitoring 

objectives defined in appendix D to this part, whether new sites are needed, 

whether existing sites are no longer needed and can be terminated, and whether 

new technologies are appropriate for incorporation into the ambient air 

monitoring network. The network assessment must consider the ability of existing 

and proposed sites to support air quality characterization for areas with relatively 

high populations of susceptible individuals (e.g., children with asthma), and, for 

any sites that are being proposed for discontinuance, the effect on data users 

other than the agency itself, such as nearby States and Tribes or health effects 

studies. For PM2.5, the assessment also must identify needed changes to 

population-oriented sites. The State, or where applicable local, agency must 

submit a copy of this 5-year assessment, along with a revised annual network 

plan, to the Regional Administrator. The first assessment is due July 1, 2010.

(e) All proposed additions and discontinuations of SLAMS monitors in annual 

monitoring network plans and periodic network assessments are subject to 

approval according to §58.14.
