# INTRODUCTION

An annual review of the Air Quality Monitoring Network is required by Federal Regulations as a

means to identify and report needs for additions, relocations, or terminations of monitoring sites

or instrumentation. This report describes the network of ambient air quality monitors in the

jurisdiction of and operated by the South Coast Air Quality Management District (South Coast

AQMD) . It includes a review of actions taken during the 20 11

- 201 2 fisca l year and plans for

action in the year ahead. This final plan addresses the requirement for an annual network plan as

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

Regulations require the report be submitte d to the U.S. Environmental Protection Agenc y (EPA)

by July 1 of each year after a 30 day public comment period.

The South Coast AQMD staff, along with the California Air Resources Board (CARB),

conducted an extensive review of the air monitoring sites in the South Coast Air Basin ( SCAB )

in late 1980. During the review

, State and Local Air Monitoring Stations (SLAMS)

designations, monitoring objectives, and spatial scales of representativeness were assigned to the

criteria pollutants monitored at each sit e

. Since that time, the EPA Region IX and CARB staff

visited selected sites to confirm compliance with applicable siting criteria and related

requirements. The most recent site visits occurred in 20 10 to conduct a comprehensive

Technical System Audit (TS A) of the ambient air monitoring network. Each year, South Coast

AQMD staff conducts an annual revie w of its air monitoring network and submits it to the EPA.

The review process focuses on current and future ne twork air monitoring strategies and network

c hanges are made in consultation with the E PA and CARB. When re

- location of monitoring

sites are required, site reports are updated in the EPA’s Air Quality System (AQS) to document

compliance with established siting criteria for the new locations.



## Public Comments

Pursuant to Federal regulations, a draft plan is made available for public inspection and

comments for at least 30 days prior to submission to the EPA. Hard copies of the final document

are made available on July 1, 201 2 at the South Coast AQMD ’s Public Information Desk in

Diamond Bar, CA. The document is also available on the South Coast AQMD webs ite at

www.aqmd.gov as of July 1, 201 2

, in the drop down menu under the “Community” and “Air

Quality” section of the website. The f inal document is submitted to the EPA on July 1, 201 2

along with any public comments received to fulfill Fe deral regulatory requirements.



## Network Design

The South Coast AQMD operates 3 5 permanent, multi

- pollutant monitoring stations , a nd 5 Lead

( Pb ) air monitoring sites in the SCAB and a portion of the Salton Sea Air Basin in Coachella

Valley. This area includes Orange County and the non

- desert portions of Los Angeles,

Riverside

, and San Bernardino Counties. The newest pe rmanent site was added during June

2010 to monitor Ozone (O3) and continuous PM 2.5 for the Temecula area

. T he newest source

Pb sites were added in January 2010 as required by EPA regulation. T he Mira Loma High

School (Jurupa) site was closed in May 2011 and is replace d by the Mira Loma ( Van Buren )

location. Table 1 provides a list of monitoring locations, the EPA AQS site codes, and the

pollutants measured at each site. Table 2 provides the monitoring objective and the spatial scale

for each monitor at all sites

.

### Air Quality Monitoring Network Plan

– July 2012

2 Ta ble 3 describes the monitoring purpose for the monitors at each site. Table 4 describes the

monitoring objective, purpose, and spatial scale for continuous particulate analyzers at each site.

A new requirement of the annual network plan implemented in 20 07, the monitoring purpose is

the reason why a certain pollutant is being measured at a certain site. A list and description of

monito ring purposes are provided below and portions are adapted from the CARB annual

network plan for 2007.

Background Level monitoring is use d to determine general background levels of air

pollutants as they enter the SCAB

.

High Concentration monitoring is conducted 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 (i.e., due to varying meteorology year to year).

Pollutant Transport is the movement of pollutant between air basins or areas within an air

basin. Transport monitoring is use d to assess and m itigate upwind areas when transported

pollutant affects neighboring downwind areas. Also, transport monitoring is use d to

determine the extent of regional pollutant transport among populated areas and to rural

areas.

Population Exposure monitoring is con ducted to represent the air pollutant concentrations

that a populated area is exposed to.

Representative Concentration monitoring is conducted to represent the air quality

concentrations for a pollutant expected to be similar throughout a geographical are a. 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 qua lity. The air pollutant sourc es may be

stationary or mobile.

Trend Analysis monitoring is useful for comparing and analyzing air pollution

concentrations over time. Usually, trend analyses show the progress or lack of progress in

improving air quality f

or an area over a period of many years.

Site Comparison monitoring is used to assess the effect on measured pollutant levels of

moving a monitoring location a short distance (usually less than two miles). Some

monitoring stations become no longer usable due to development, change of lease terms, or

eviction. In these cases, attempts are made to conduct concurrent monitoring at the old and

new site for a period of at least one year in order to compare pollutant concentrations.

Real Time Reporting/Modelin g is used to provide data to EPA’s AIRNOW system which

reports conditions for air pollutants on a real time basis to the general public. Data is also

used to provide accurate and timely air quality forecast guidance to residents of the SCAB.

### Air Quality Monitoring Network Plan

– July 2012

3 Multiple pur poses for measuring a pollutant at a particular site are possible. There is some

overlap between monitoring objectives and monitoring purposes as defined by the EPA and

given in Tables 2, 3

, and 4

.

A brief description of the criteria pollutant and prog ram monitoring networks are provided

below:

OZONE (O3)

The South Coast AQMD operates 30 sites where O3 measurements are made as part of the

Air Monitoring Network. O 3 sites are spread through ou t the SCAB with highest

concentrations me a sured inland. Figur e 1 in Appendix A shows the spatial distribution of

these sites.

PM10

Size

- selective inlet manual high volume samplers are operated at 21 sites to meet the

requirements for PM10 Federal Reference Method ( FRM ) sampling . The Indio , Los

Angeles, Ontario, and Rubidoux sites are designated as collocated sites as shown in the

minimum monitoring requirements and Table 3

. All PM 10 FRM monitors operate on a

one day in six day schedule, with the exception of Indio and Rubidoux which operate on

one day in three day schedule.

PM 10 continuous analyzers are operated at 14 sampling sites . These real

- time devices are

capable of making hourly particulate concentration measurements. Table 4 describes the

monitor type, monitoring objective, purpose, and spatial scale for continuous parti culate

analyzers at each site. F igure 2 in Appendix A shows the spatial distribution of the

sampling sites. Real

- time monitors, for the most part, are clustered in the high

concentration areas, with two located in the desert area where wi nd

- blown crustal material

has caused exceedences of the twenty

- four hour s tandard during exceptional events . In

downwind areas of the SCAB , a large fraction of particulate is formed in the atmosphere;

PM 10 reaches maximum levels during late summer through early winter months.

Where both s ize

- selective inlet manual high volume samplers and PM10 continuous

analyzers are deployed together they are sited as collocated for data comparison purposes.

The PM10 manual high volume sampler remains the primary ana lyze r used for attainment

purposes and continuous analyzers are designated as audit samplers

.

NITROGEN DIOXIDE (NO2)

The NO 2 network consists of 25 sites . These sites are mostly located in areas of highest

NO 2 concentration. The spatial distribution of N O 2 monitors is shown in Figure 3 in

Appendix A

. Review of 1992 through 20 11 data indicates that State and Federal standard s

for NO2 were not exceeded.

CARBON MONOXIDE (CO)

Ambient CO monitors measure concentrations at 2 5 locations. Figure 4 in Appendix A

shows the spatial distribution of these sites. CO emissions, primarily from motor vehicles,

### Air Quality Monitoring Network Plan

– July 2012

4 show a pattern consistent with major freeway arteries. A review of data for 2011 indicates

State and Federal standards for CO were not exceeded.

SULFUR DIOXIDE ( SO2)

SO2 monitors are located at 7 sites

. Figure 5 in A ppendix A shows the spatial distribution

of the sites. Most SO 2 emissions come from F ederal transportation sources such as marine

vessels . The monitors are clustered mostly in the areas where these sources are located.

On June 22, 2010 EPA strengthened the SO2 National Ambient Air Quality Standard

(NAAQS) . Network design requirements included new minimum requirements be

determined by the Population Weighted Emissions Index (PWEI)

.

The PWEI shal l be calculated by States for each C ore B ased Statistical A rea

(CBSA) they contain or share with another State or States for use in the

implementation of or adjustment to the SO2 monitoring network. The PWEI shall

be calculated by multiplying the populatio n of each CBSA, using the most current

census data or estimates, and the total amount of SO2 in tons per year emitted

within the CBSA area, using an aggregate of the most recent county level

emissions data available in the National Emissions Inventory (NEI ) for each

county in each CBSA. The resulting product shall be divided by one million,

providing a PWEI value, the units of which are million persons

- tons per year. For

any CBSA with a calculated PWEI value equal to or greater than 1,000,000, a

minimum of three SO2 monitors are required within that CBSA. For any CBSA

with a calculated PWEI value equal to or greater than 100,000, but less than

1,000,000, a minimum of two SO2 monitors are required within that CBSA. For

any CBSA with a calculated PWEI value eq ual to or greater than 5,000, but less

than 100,000, a minimum of one SO2 monitor is required within that CBSA.

South Coast AQMD exceeds the minimum requirement for SO2 monitors; t he F ederal

standard has not been exceeded for nearly 3 2 years.

PARTICULATE LEAD

Total Suspected P articulate (TSP) Pb measurements are collected at 1 5 sites as part of the

network; 5 of the sites are Source Impact for Pb, and the remaining 10 sites measure

ambient Pb, and S ulfates ( SO 4)

. 

### There are 4 a dditional sites which measure SO4 only for a

total of 19 TSP particulate sites. The Vernon (Rehrig), Long Beach, Los Angeles , and

Riverside sites are designated as collocated sites as shown in the minimum monitoring

requirements and Table 3. The spatial distribution of these sites is shown in Figure 6 in

Appendix A

. In 1990, the EPA requested that the South Coast AQMD collect ambient air particulate

samples near several large Pb handling (battery recycling) facilities. Long

- term source

impacted monitorin g began in 1991. A facility in the City of Industry exceeded the F ederal

### Air Quality Monitoring Network Plan

5 ambient particulate Pb standard during the second quarter of Fiscal Year 1991

- 92

. Pb

monitoring at a facility in the City of Torrance ended in 1993 when measurements were

consistentl y below the ambient standard. Sampling ended at a facility in the City of

Commerce in 2006 when the business was closed. Out of the two facilities currently being

monitored, the facility in the C ity of Vernon exceeded the old F ederal ambient particulate

Pb standard (1.5 ug/m3 quarterly) during the first quarter of 2008; the other facility was

found to remain below this level. These source

- related Pb sites are also depicted in

Figure 6.

On November 12, 2008, the EPA issued final revisions to the NAAQS fo r Pb

. N etwork

design requirements include d monitoring for sources of Pb (s ource oriented monitoring)

and urban Pb monitoring (non

- source oriented). To meet this requirement, a source

oriented site w as established on January 1, 2010 at the Van Nuys Airpor t and monitoring

will continue at the sites surrounding the Exide (Vernon), Quemetco (Industry), and the

Trojan Battery facilities. Existing urban Pb monitoring conducted at Compton, LAX

Hastings, Long Beach (North), Los Angeles (Main), Pico Rivera, River side Magnolia,

Rubidoux, San Bernardino, South Long Beach, and Upland exceed the minimum

monitoring requirements

.

The final rule for Pb went into effect on January 26 , 2011. In the final rule the Van Nuys

Airport was no longer included on the list of air ports where lead monitoring was required

, and a more recent emissions inventory showed lead emissions less than 1 ton per year

. The data from the Van Nuys Airport Pb site is currently under review to determine the

need for continued monitoring.

Photochemi cal Assessment Monitoring Stations

The Photochemical Assessment Monitoring Stations ( PAMS ) network was initiated in

June 1994 at Pico Rivera and Upland . During 1995 sites were established at Banning and

Azusa to determine speciated hydrocarbon O 3 precurso r compounds in ambient air.

PAMS monitoring at Hawthorne commenced in June 1997 and the Burbank station

became a PAMS site in July 1997. In May 2001, the Santa Clarita location was

established as a PAMS site. In April 2004, the Hawthorne site was replac ed by LAX

Hastings, due to the end of a property lease. In August 2005, the Pico Rivera station

moved to a new location one half mile south of the previous site, also due to the end of the

property lease.

On October 17, 2006, the EPA issued final amendme nts to PAMS monitoring

requirements in 40 CFR § 58 . The changes made to the rule were to implement

recommendations made by the PAMS workgroup formed to assess the program. The

workgroup recommended changes be made to site type and monitoring objectives. During

September 2008, a report from the EPA PAMS network assessment project workgroup was

issued. The objectives of the workgroup were to assess how well the current PAMS

network was meeting monitoring objectives, determine which sites are most useful f or

meeting objectives, identify potentially redundant, ineffective, or unnecessary sites, and to

assess other enhanced O 3 monitoring activities that may prove useful.

### Air Quality Monitoring Network Plan

– July 2012

6 To address regulatory changes, site

- specific observations from the PAMS network

assessm ent project, and potential synergies between programs, South Coast AQMD made

the following changes in June 2009 to the PAMS monitoring network:

 Burbank was reclassified from Type 2/1 to Type 2. This change addressed the

National PAMS Network Assessment o bservation that Burbank should be reclassified

to a Type 2 precursor site. The recommendation is consistent with the heavily

urbanized/industrialized area, which is impacted by high levels of O3 precursor

emissions.

 Santa Clarita was reclassified as Ty pe 3 from Type 2. Although the National PAMS

Ne t work Assessment observed that Santa Clarita was consistent with a Type 2 site,

recent data was more consistent with a Type 3 maximum O3 concentration site rather

than a Type 2 O3 precursor site.

 Banning was relocated to Los Angeles (Main). The National PAMS Network

Assessment observed that Banning had the lowest O3 concentrations of all the Type 2

sites and should be reclassified to a Type 3 or 4 site. Instead, to create synergies

between programs, South Co ast AQMD relocated the Banning PAMS site to the Los

Angeles (Main) site as Type 2. This satisfies the EPA recommendation for use of the

same monito r ing platform and equipment to meet the objectives of multiple

programs. Los Angeles (Main) is also a Nation al Air Toxics Trends Station

(NATTS), a National Core

- Multi

- pollutant Monitoring Station (NCore), and a

Speciation Trends Network (STN) site.

 Azusa was reclassified from Type 3 to Type 2. This proposed change addresses the

National PAMS Network Assessment observation that Azusa has high Volatile

Organic Compounds (VOC) and Oxides of Nitrogen (NOX) concentrations, with

lower O3 concentrations. The site now more closely resembles a Type 2 O3

precursor site.

 Upland was relocated to the Rubidoux site. The Na tional PAMS Network

Assessment observed that Upland was no longer consistent with a Type 4 site and

reco m mended reclassification to Type 3. South Coast AQMD relocated the Upland

PAMS site to Rubidoux as a Type 3 location where synergies can be created amo ng

the NATTS , NCore, and the STN programs.

 LAX Hastings and Pico Rivera remained unchanged.

Currently, manual VOC canisters are in operation at the Azusa, LAX Hastings, Rubidoux,

Los Angeles (Main)

, and Santa Clarita air monitoring stations. During the i ntensive season

from July 1 until Se p tember 30, VOC canisters are run every three hours for a period of

twenty

- four hours every 3rd day and a twenty

- four hour sample is run every 6th day.

During the non

- intensive season from October 1 through June 30, twe nty

- four hour VOC

canister samples are run every 6th day.

At Los Angeles (Main) and Santa Clarita air monitoring stations, during the intensive

season from July 1 until September 30, carbonyl samples are run every three hours for a

period of twenty

- four h ours every 3rd day and a twenty

- four hour sample is run every 6th

day. During the non

- intensive season from October 1 through June 30, twenty

- four hour

carbonyl samples are run every 6th day.

### Air Quality Monitoring Network Plan

– July 2012

7 Automated G as Chromatography F lame I onization D etector (GC \ FID ) VOC systems are in

operation at the Pico Rivera and Burbank air monitoring stations. During the intensive

sampling season from July 1 until September 30, the GC \ FID is run to collect daily 3

- hour

samples and twenty

- four hour VOC canisters are run every 6th day. Like the other PAMS

sites, carbonyl samples are run every three hours with one additional twenty

- four hour

sample run every 6th day. During the non

- intensive season from October 1 through June

30, the GC/FID is idle and twenty

- four hour VOC cani ster samples are run every 6th day

and twenty

- four hour carbonyl samples are run every 6th day. Rubidoux is a collocated

site for VOC canister sampling and Pico Rivera is a collocated site for VOC canister and

carbonyl sampling.

During April 2010, a sy stem audit was co n ducted by the EPA, which asse ssed the South

Coast AQMD NATTS/PAMS program s . The audit found no major issues with the

operation of the network but recommended implement a tion of blanking and low level

concentration challenge samples for th e NATTS and PAMS programs . Blanking was

implemented in June, 2010 and low level challenge samples were implemented during

October, 2010

.

The first South Coast AQMD upper air meteorological monitoring station was established

at Los Angeles International A irport (LAX) in 1994. Subsequent upper air stations include

Ontario International Airport (ONT) installed in 1996, Moreno Valley (MOV) installed in

2001 at the Moreno Valley Municipal Water Treatment Plant in R i verside County, Irvine

installed at the Univ ersity of California Research and Extension Center in 2006, and

Pacoima at Whiteman Airport during May 2007. The upper air st a tions use a combination

of remote sensing and surface meteorological instrumentation, including the Vaisala

(formerly Radian/URS) LAP

- 3000 radar wind profiler with a Radio Acoustic Sounding

System (RASS), the Atmospheric Systems Corporation (formerly AeroVironment Inc.)

mini Sodar acoustic wind profiler, and tower

- mounted meteorolog i cal measurements of

wind, pressure, temperature, r elative humidity, solar radiation

, and ultraviolet radiation.

The PAMS network monitoring objectives and requirements are summarized in T able 6

and Figure 7 in Appendix A shows the distribution of the PAMS network.

PM2.5

A network of 17 FRM samplers was f irst implemented in January 1999. On December 26,

1999, a second Coachella Valley PM2.5 sampling site was established in Palm Springs.

On June 20, 2003, PM2.5 sampling began at the South Long Beach site. The final addition

to the PM2.5 FRM network occurr ed in October 2005, at the new Mira Loma site. This

brings the total number of PM2.5 FRM sampling sites to 20. The sites are depicted in

Figure 8, Appendix A and the starting date of each sampler is listed in Table 5. In March

2012, a change was made re locating the collocated PM2.5 monitor from Indio to the Mira

Loma (Van Buren) site. This change was made following approval from EPA. Collocated

sampling sites include Rubidoux, Central Los Angeles, and Mira Loma (Van Buren) . All

sites in the Network usi ng FRM samplers are suitable for comparison against the annual

PM2.5 NAAQS.

### Air Quality Monitoring Network Plan

– July 2012

8 During April 2009, South Coast AQMD completed minor changes to the FRM monitoring

schedule to enhance Federal Equivalent Method ( FEM ) Beta Attenuation Monitor ( BAM )

comparisons. On April, 16th, 2009 the Burbank and Mira Loma (Van Buren) FRM

samplers changed to daily sampling from the current 1

- in

- 3 day schedule and the Azusa

location changed from every day sampling to 1

- in

- 3 day sampling. Federal minimum

monitoring requirements f or PM2.5 are still being met and/or exceeded.

Continuous PM2.5 Met One BAMs were first deployed in fiscal year 2001

– 02. Seventeen

monitors are now operating in the SCAB , two at Rubidoux (collocated), and one each at

Anaheim, Los Angeles, South Long Beach , Burbank, Mira Loma (Van Buren), and

Banning. In January 2006, two additional samplers were added at Lake Elsinore and

Glendora as part of the Children’s Health Study. As proposed in the 2008 network plan,

FEM BAM monitors were deployed during October 2 008, at the Anaheim, Burbank, Long

Beach (North), Los Angeles (Main), Mira Loma (Van Buren), Rubidoux, and South Long

Beach sites. Relocated NON

- FEM BAM samplers were installed at Reseda, Riverside

Magnolia, Santa Clarita, Crestline, and Upland . A NON

- F EM BAM was collocated with a

FEM BAM at Rubidoux. An additional BAM sampler was deployed at Temecula during

July, 2010

. In 2011

, all FEM BAMs with the exception of Temecula have been

reclassified from special purpose monitors to SLAMS under 40 CFR § 58.2 0

.

Where both 24 hour FRM PM2.5 samplers and FEM PM 2.5 continuous analyzers are

deployed together

, they are sited as collocated for data comparison purposes. The 24 hour

FRM PM2.5 s ampler remains the primary analyzer used for attainment purposes and

cont inuous analyzers are designated as audit samplers

.

PM2.5 speciation sampling is also a part of the South Coast AQMD PM2.5 program.

Collocated S TN and one South Coast AQMD Met One SASS PM2.5 samplers were

deployed in March 2001 at Rubidoux. An additiona l STN and collocated South Coast

AQMD SASS samplers were deployed at Central Los Angeles in 2002. In 2003, SASS

PM2.5 speciation samplers were installed at Fontana and Anaheim air monitoring sites.

Analysis of the filters from the ambient network SASS s amplers are being conducted at

South Coast AQMD’s laboratory. The STN filters are shipped to Research Triangle

Institute ( RTI ) for analysis. This approach has the concurrence of CARB and EPA,

Region IX.

Natio nal A ir Toxics Trends Station

The NATTS progra m was developed to fulfill the need for long

- term H azardous A ir

P ollutant (HAP) monitoring data of consistent quality nationwide. South Coast AQMD

has conducted several air toxics measurement campaigns in the past, which demonstrated

the variety and spati al distribution of air toxics sources across SCAB. A single air toxics

me a surement site cannot reflect the levels and trends of air toxics throughout the SCAB

. For this reason, two NATTS sites are used to characterize the SCAB’ s air toxics levels.

The fi rst site is a central urban core site in Los Angeles that reflects concentrations and

trends due primarily to urban mobile source emi s sions. A second, more rural, inland site at

Rubidoux captures the transport of pollutants from a variety of upwind mobile and

### Air Quality Monitoring Network Plan

– July 2012

9 industrial sources in the most populated areas of the air basin. NATTS monitoring began

in February 2007 and continues at the Los Angeles (Main) and Rubidoux air monitoring

sites. During April 2010, a system audit was co n ducted by the EPA, which ass essed the

South Coast AQMD NATTS program. The audit found no major issues with the operation

of the network but recommended implement a tion of blanking and low level concentration

challenge samples for the NATTS and PAMS programs . Blanking was implemented in

June, 2010 and low level challenge samples were implemented during October, 2010

.

NCore

NCore monitoring rules require that South Coast AQMD make NCore sites operational by

January 1 st 

### , 2011. To meet this goal, South Coast AQMD installed t race level a nalyzers

for CO, NOY and SO2 at the Rubidoux and Central Los Angeles sites. Final calibrations

were completed at the Rubidoux site January, 2011 and at the Central Los Angeles during

May, 2011. Both the Los Angeles and Rubidoux sites are NATTS and PAMS monitoring

locations.



## Special Programs

Special monitoring programs are conducted for rule compliance purposes

, to characterize the

levels of toxic air contaminants and other criteria pollutants in sub

- regional areas or communities

in the SCAB , or to su pport modeling and planning efforts. The following is a list of special

monitoring programs that were active during the past year. Note that this is being provided for

informational purposes only.

MATES IV

The SCAB , a highly urbanized area, is home to about sixteen million people who own and

operate about eleven million motor vehicles and contains some of the highest

concentrations of industrial and commercial operations in the country. It also has the

poorest air quality in the U.S. In 1986, S outh C oast AQMD conducted the first MATES

study to determine the SCAB

- wide risks associated with major airborne carcinogens. At

the time the state of technology was such that only ten known air toxic compounds could

be analyzed. In 1998, a second MATES study ( MATES II) represented one of the most

comprehensive air toxics measurement programs conducted in an urban environment.

MATES II included a monitoring program of 40 known air toxic compounds, an updated

emissions inventory of toxic air contaminants, and a modeling effort to characterize health

risks from hazardous air pollutants. In April 2004, the South Coast AQMD initiated the

third round of MATES (MATES III) to assess the ambient levels of airborne compounds

linked to adverse health effects in humans. I n June, 2012 South Coast AQMD will begin

MATES IV.

The objective of MATES IV is to characterize the ambient air toxic concentrations and

potential exposures in the SCAB. This project includes one year of ambient monitoring for

air toxics which will have a combination of SCAB

- wide measurements and localized

studies. The project will develop an updated toxics emissions inventory and conduct air

dispersion modeling to estimate ambient levels and the potential health risks of air toxics.

### Air Quality Monitoring Network Plan

– July 2012

10 The results of this effort will determine the spatial concentration pattern of important

hazardous air pollutants in the SCAB , will assess the effectiveness of current air toxic

control measures, provide trend data of air toxic levels, and be used to update and develop

appro priate control strategies for reducing exposures to toxics associated with significant

public health risks.

MATES IV proposes to enhance the spatial resolution of previous studies by

characterizing the ambient concentration of selected toxic air compounds in communities

with varying land

- type usage, such as residential, industrial, and commercial, as well as

gradients from source areas downwind to receptor areas.

MATES IV monitoring sites will utilize MATES III sites for trend analysis. There are ten

f ixed sites operating on a one

- in

- six day schedule for twenty

- four hours. Monitoring

locations include the Anaheim, Burbank, Compton, Fontana, Huntington Park, North Long

Beach, LA Main Street, Pico Rivera, Rubidoux

, and West Long Beach areas . MATES IV

wi ll add Ultra Fine Particulate (UFP) and Black Carbon (BC) continuous measurements

. Mobile monitoring platforms are to be deployed for short term deployments at six to eight

sites to include communities with varying land type usage

.

Fugitive Dust Study

In support of South Coast AQMD Rule 403

- Fugitive Dust, SSI PM10 samplers are

deployed on an episodic basis upwind and downwind of potential sources as required

under Rule 403. Since 2003, periodic sampling has been conducted around gravel quarries

and o ther industries which seem to be pr oducing large volumes of dust.

Hexavalent Chrome

The South Coast AQMD has an ongoing program of collecting ambient hexavalent

chromium in the vicinity of several chrome plating and cement production facilities located

throughout the SCAB . Monitoring continues at Newport Beach, Riverside, and other

locations throughout the South Coast AQMD jurisdiction.

College of the Desert

Because exceedances of the standard PM 10 have been recorded at the Torres

- Martinez

(Indian Res ervation) station, South Coast AQMD is conducting an independent monitoring

study to evaluate the spatial representativeness of such measurements. A continuous PM10

monitor was set

- up near “College of the Desert” on 12/07/10 where measurements

continue to be taken.



## Recent or Proposed Modifications to Network

Near Roadway NO2 Monitoring

On February 9

, 2010, U.S. EPA promulgated new minimum monitoring requirements for

the NO 2 monitoring network in support of newly revised 1

- hour NO2 NAAQS and the

retained a nnual NAAQS. In the new monitoring requirements, S tate and L ocal air

monitoring agencies are required to install near

11 environment in l arger urban areas. State and local air agencies are required to consider

traffic volumes, fleet mix, roadway design, traffic congestion patterns, local terrain or

topography, and meteorology in determining where a required near

- road NO 2 monitor

should be p laced. In addition to those required considerations, there are other factors that

impact the selection and implementation of a near

- road monitoring station including

satisfying siting criteria, site logistics (e.g., gaining access to property and safety), and

population exposure

.

The near roadway grant guidance directed implementation of near road sites be conducted

in phases . Phase I sites include one site in the Los Angeles

– Long Beach

– Santa Ana

(Metropolitan Statistical Area (MSA) and one in the R iverside

– San Bernardino

– Ontario

MSA . These sites are to be established and operating by January 1, 2013. The current

funding level is intended to cover the costs of these two sites. EPA will announce a

schedule for additional implementation at a lat er date as funding becomes available

.

The primary objective of the near

- road NO 2 network is to place monitoring resources on

near

- road locations where peak, ambient NO 2 concentrations are expected to occur as a

result of on

- road mobile source emissions. Monitoring at such a location or locations

within a particular urban area will provide data that can be used for comparison to the

NAAQS and to assess population exposures for those who live, work, play, go to school,

or commute within the near

- roadway e nvironment. The near

- road NO 2 data will provide a

clear means to determine whether or not the NAAQS is being met within the near

- road

environment throughout a particular urban area. Since near

- road NO 2 monitoring sites are

to be placed at locations with expected peak NO2 concentrations, and the target mobile

sources and the roads they travel upon are ubiquitous throughout urban areas, these

monitoring data may be said to represent the relative worst case population exposures that

may be occurring in the n ear

- road environment throughout an urban area over the

averaging times of interest.

Following the guidance of the U.S. EPA draft Near Roadway NO 2 Technical Assistance

Document (TAD) (December, 2011), identification of potential monitoring sites is

complet ed by assessment of six factors including: Annual Average Daily Traffic (AADT)

, fleet mix, congestion patterns, roadway design, terrain

, and meteorology. In addition,

South Coast AQMD has locally available data to assist in prediction of near

- road NO 2

ma ximum concentrations expected. The identified locations are to be surveyed for site

feasibility. Considerations include availability of location and lease, access to utilities,

securing permits

, and potential safety issues. Based on this guidance South C oast AQMD

had identified and begun the process to evaluate and secure potential monitoring locations.

Areas which have been identified in the Los Angeles

– Long Beach

– Santa Ana MSA

include the 605/ I

- 5 freeway interchange, 57/ I

- 5/22 freeway interchange and the 57/60

freeway interchange. Areas identified in the Riverside

– San Bernardino

– Ontario MSA

include the 60 Freeway at Euclid, 60/I

- 15 freeway interchange and the I

- 10/I

- 15 freeway

interchange. Table 7 shows AADT and Fleet Equivalent (FE) values a s determined by

TAD guidance

### Air Quality Monitoring Network Plan

– July 2012

12 Once monitoring begins , the continuous operation of instrumentation and meteorological

data will be ongoing with data reported to AQS and AIR/NOW

.

Indio PM2.5 Collocation

On March 8, 2012 after consultation with EPA the coll ocated PM2.5 monitor was moved

from the Indio air monitoring site to the Mira Loma (Van Buren) site. The Mira Loma

(Van Buren) site is the PM2.5 design site for the South Coast AQMD. The monitor was

moved to assure the consistency of the data at the Mira Loma site and to serve as a backup

monitor in case of primary instrument failure.

Van Nuys Pb Monitoring S ite

On November 12, 2008, the EPA issued final revisions to the NAAQS for Pb. Network

design requirements included monitoring for sources of Pb (so urce oriented monitoring)

and urban Pb monitoring (non

- source oriented). To meet this requirement, a source

oriented site w as established on January 1, 2010 at the Van Nuys Airport . The final rule

for Pb went into effect on January 26, 2011. In the fina l rule the Van Nuys Airport was no

longer included on the list of airports where lead monitoring was required, and a more

recent emissions inventory showed lead emissions less than 1 ton per year. The data from

the Van Nuys Airport Pb site is currently un der review to determine the need for continued

monitoring. Changes to the Pb monitoring network will be made upon after consultation

with EPA.

Sulfate Monitoring

South Coast AQMD has been monitoring TSP sulfate data at the Banning, Fontana,

Pasadena

, an d West Los Angeles monitoring since the inception of the monitoring sites. In

2003 , ARB r evise d the sulfates monitoring method and standard by deleting the TSP

sulfates method, ARB method MLD 033, and replaced it with the existing ARB method

and creating a new standard for PM10 sulfates, ARB method MLD 007

. ARB conducted a

comparison of South Coast AQMD PM10 and TSP sulfate data for 1999 though 2010 and

found good correlation between the two methods. TSP sulfate data is currently being

reviewed in consul tation with EPA and ARB to determine the need for continued TSP

sulfate monitoring.

L a Habra

South Coast AQMD has been operating the La Habra site since 19 60 . The deteriorating

state of the shelter along with compromises made to the siting criteria due t o obstructions

has made it a candidate for site improvement . As part of regular air monitoring station

maintenance, the station shelter was replaced in FY 2011

- 12.

Pasadena

South Coast AQMD has been operating the Pasadena site since 1982 . The deteriorat ing

state of the shelter along with compromises made to the siting criteria due to obstructions

has made it a candidate for site improvement . As part of regular air monitoring station

maintenance

, a new station shelter as been modified t o replace the exist ing trailer during

FY 2012

- 13

.

### Air Quality Monitoring Network Plan

– July 2012

13 Crestline

South Coast AQMD has been operating the Crestline site since 19 73 . The deteriorating

state of the shelter along with compromises made to the siting criteria due to obstructions

has made it a candidate for site imp rovement. As part of regular air monitoring station

maintenance

, a new station shelter as been ordered t o replace the existing trailer during FY

201 2

- 13

.

South Long Beach

South Coast AQMD has been operating the South Long Beach station as part of the

ambi ent air

- monitoring network. Recent construction of the buildings adjacent to our air

monitoring equipment compromises the siting criteria. During the FY 2012

- 13 a data

comparison between a more centralized monitoring location in Long Beach will be

undert aken. If comparison of data between the two locations demonstrates some

comparability, or if the metropolitan site shows consistently higher levels of PM, the South

Long Beach site may be relocated after consultation with EPA

.

Air Monitoring Station Imp rovements

As part of the actions to enhance q uality of data collected, South Coast AQMD will

replace existing deteriorated shelters at the Indio , San Bernardino, West Los Angeles and

Perris monitoring sites . The new shelters will be installed at the same locations as the

existing structures.



## Minimum Monitoring Requirements

The South Coast AQMD jurisdictional boundary encompasses two MSA s and two CBSAs

whose boundaries and codes mirror those of the MSAs as defined by the U.S. Office of

Management and Budg et. The Los Angeles

- Long Beach

- Santa Ana MSA \ CBSA (Code 31100)

had a population of 12,874,797 based on 2009 U.S. Census Estimates . The Riverside

- San

Bernardino

- Ontario MSA \ CBSA (Code 40140) had a population of 4,224,851 based on 2009

estimates . The mini mum number of monitors for each pollutant is based on MSA population as

described in 40 CFR § 58 Appendix D. T he S outh C oast AQMD is a Primary Quality Assurance

Organization (PQAO) and the network exceeds the minimum monitoring requirements for all

criter ia pollutants. Details are provided below.
