### 1.0 I ntroduction

State and Local agencies that conduct ambient air monitoring for regulatory purposes are

required, by Title 40, Code of Federal Regulat ions, Part 58.10 ( 40 CFR 58 .10) , to submit a n

Annual Monitoring Network report to the Environmental Protection Agency ( EPA ) , no later

than July 1 st 

### , each year, starting July 1, 2007. The report must contain specific monitoring

network information and the report must be presented for a 30

- day public review period prior to

submittal to EPA. This report covers the period: January 1, 200 9

- December 3 1 , 200 9.

The primary purpose of this ambient air monitoring network report is to document the existing

Sacrame nto County State and Local Air Monitoring sites (SLAMS) , which also includes NCore,

Speciated Trend Network (STN), Special Purpose Monitoring (SPM), and Photochemical

Assessment Monitoring (PAMS) sites, operated by our District and CARB, and to show that t he

ambient air monitoring network meets the requirements of 40 CFR 58, including Appendix A, C,

D, and E, where applicable. The report will include the F e d eral Reference Method ( FRM )

, Federal Equivalent Method ( FEM ) , and Approved Regional Method ( ARM ) mon itors. Though

not required by 40 CFR Part 58, the report also discuss es additional SPM monitoring

instrumentation being operated, such as Aethalometer s and Nephelometer s, and surface/upper air

meteorological sensors required for the PAMS program. The sec ondary purpose of this report is

to discuss proposed changes (additions, relocations, and terminations of non

- SPM monitors) in

the ambient air monitoring network that may be proposed to occur within an 18 month period

following submittal of this report.

T his report is not an "in depth" analysis of the local a ir m onitoring n etwork design. An in

- depth

analysis of the monitoring network is required every 5 years to determine, at a minimum, if the

network meets the monitoring objectives defined in 40 CFR Part 58 Appendix D, whether new

sites are needed, whether existing sites are no longer needed, and whether new technologies are

appropriate for incorp oration in to the ambient air monitoring network. This analysis is due July

1, 2010.



### 2.0 Overview of Network Operations

The County of Sacramento is located in the middle of California's Central Valley, at the southern

end of the Sacramento Valley. Sacramento County has a population of 1.4 million. Sacramento

County is the most populated part of the Sacramento

-- Arden Arcade

-- Roseville, C alifornia

Metropolitan Statistical area ( MSA ) which includes the western sections of Placer and El Dorado

County, Yolo County, and parts of Solano and Sutter Counties. The Sacramento MSA is the 2 5 th



### largest MSA in the USA

, base d upon population , with a population of 2. 1 million people 1



### . The

Sacramento MSA is a non

- attainment area for the Federal 8 hr averaged O 3 

### standard and is

referred to as the Sacramento Federal Nonattainment Area (SFNA)

. This network plan focuses

on the m onitors that are operated within Sacramento County. For details on the monitors

operated in the other counties within the SFNA , please refer to the Annual Monitoring Network

Report for Small Districts in California dated June 200 9 prepared by the Californ ia Air

Resources Board (http://www.arb.ca.gov/aqd/amnr/smnetrpt.doc)

### 2.1 Monitoring Objectives and Spatial Scales

The b asic three monitoring objectives are to: 1) provide air pollution data to the general public

in a timely manner; 2) support compliance with ambient quality standards and emission strategy

development; and 3) support air pollution research studies. To sup port these monitoring

objectives there are a variety of types of monitoring sites including sites located to determine the

highest pollutant concentration, the representative concentrations in areas of high population

density , the impact of major pollution emissions sources, the general background concentration

levels, the extent of pollutant transport, and impacts on visibility, vegetation, and other welfare

based impacts.

The physical sitting of an air monitoring station must achieve a spatial scale of

r epresentativeness that is consistent with the monitoring objective of the monitor. The spatial

scale results from the physical location of the site with respect to the pollutant sources. It

### - 6

-

estimates the size of the area surrounding the monitoring site t hat experiences uniform pollutant

concentrations. Table 2 shows the different types of site and the appropriate spatial scale. Table

3 shows each of the monitoring sites in Sacramento County and its criteria pollutant monitoring

objective s and spatial sc ales.

The categories of spatial scale are:

Microscale

– An area of uniform pollutant concentration ranging from several meters up

to 100 meters.

Middle Scale

– Uniform pollutant concentrations in an area of about 100 meters to 0.5

kilometers

Neighborh ood Scale

– An area with dimensions in the 0.5 to 4.0 kilometer range.

Urban Scale

– Citywide pollutant conditions with dimensions ranging from 4 to 50

kilometers.

Regional Scale

– A large area, usually rural, of the same general geography and without

la rge sources that extends from tens to hundreds of kilometers.

### 3.0 Minimum Monitoring Requirements

Sacramento County is within the Sacramento

- Arden Arcade

- Roseville MSA as discussed in

Section 2.0. The minimum number of monitors f or each pollutant is based on the MSA

population as described in 40 CFR 58 Appendix D. The Sacramento

- Arden Arcade

- Roseville

MSA has a population of 2. 1 million. Th e monitoring network within the MSA exceeds the

minimum monitoring requirements for all cr iteria pollutants. Details are provided below in

must be described in the Annual Monitoring Plan, due to EPA, no later than July 1, 2010.

### 4.0 Recent or Proposed Modifications to the Network

The 2008 revised Pb NAAQS is under review . O n c e it is finalized, the District will work to meet

the monitoring requirements as promulgated in the final ruling. A low volume Pb

- PM 1 0 sampler

will be installed , at our Sacramento NCore monitoring site, to satisfy the population

- base d lead

monitoring requirement as listed in the Proposed Revisions to Pb Ambient Air Monitoring

Requirements (December 2009, Docket ID No. EPA

- HQ

- OAR

- 2006

- 0735 ).

Pb

- PM10 data may be used to show only non

- attainment or unclassified status. Pb

- TSP data

may be used to show attainment or non

- attainment status.

As per 40 CFR 58, Appendix C, Section 2.10.2, (1) the District will install and operate a Pb

- TSP

sampler at Sacramento

- Del Paso Manor within six months

, i f the maximum Pb

- PM10 three

month arithmetic me an concentration is greater than or equal to 0.10 ug/m3 ; (2) t he District may

cease operation o f the Pb

- PM10 sampler when the P b

- TSP sampler becomes operational.

Folsom

- Natoma

T he District is evaluating adding a CO monitor to this site (see discussion und er El

Camino/Watt). The CO monitor would be used to evaluate ozone model performance and

potentially compliance with the new NAAQS due to be finalized in October 2011

.

Del Paso Manor

EPA has approved, Sacramento

- Del Paso Manor , as the future NCore moni toring site , for this

MSA . Thus, the District will install a NO

y 

### analyzer , SO 2 

### trace level analyzer, a low volume

PM 10 

### FRM sampler , and a low volume Pb

- PM10 at this site, during 2010. The low volume PM 10 

### FRM sampler is needed for the PM 10

- 2.5 ( coarse ) mo nitoring , which is mandatory at all NCore

sites

. The NCore, Pb, and PM10

- 2.5 monitoring will begin, no later than January 1, 2011.

The primary reason why we plan to operate a Pb

- PM10 sampler , instead of a Pb

- TSP sampler , at

the NCore site, is that a low volume Pb

- PM10 sampler will require up less rooftop space, then a

high volume Pb

- TSP sampler. The amount of available rooftop space is limited. Thus, we wish

to effectively manage the limited amount of rooftop space available, so that we may accomplish

ou r monitoring objectives, using the least amount of rooftop space , if possible. The secondary

reason why we plan to operate a Pb

- PM10 is that the historical 1996

- 1998 Stockton Blvd and El

Camino/Watt Pb

- TSP data and the lack of large Pb emission point /area sources suggest that

ambient Pb

- TSP concentration levels , in this area, would be approximately <= 1/10 of the

revised Federal Health Standard for Pb.

In previous editions of this Annual Network Plan, we stated that we were " evaluating shutting

down the PM

- 10 TEOM monitor at this site since TEOM data is not usable for forecasting or

analysis due to negative bias during the winter time when there is wood combustion.

Termination of the TEOM will free up instrument rack space for NCore instruments. " Curre ntly,

the District is evaluating relocating the PM

- 10 TEOM from Del Paso Manor to Goldenland

Court, to free up instrument rack space , at Del Paso Manor, for NCore instrument ati on.

### - 10

-

The District is evaluating shutting down the two PM related SPM research in strument s :

Aethalometer and Nephelometer. Termination of these t wo SPM instruments will free up

rooftop space for NCore instrument ation

.

El Camino/Watt

The District is evaluating shutting down this site. It was originally installed because the District

was a CO non

- attainment area and the previous version of 40 CFR 58 required it

. This

microscale site is no longer required by regulation

. Also, t he shelter that houses the CO monitor

has dry rot and would be too costly to repair

. The CO monitor is prop osed to be re

- located to

Folsom

- Natoma to be used for verifying ozone model performance.

Stockton Blvd

The District is evaluating the possibility of shutting down the PM

- 10 SSI

, PM

- 10 TEOM , and

PM2.5 FRM at this site . The PM

- 10 SSI is not required . T he TEOM data is not usable for

forecasting or analysis due to negative bias during the winter time when there is wood

combustion. The PM2.5 FRM is redundant , as it collects the same PM2.5 data as the nearby T St

site.

Goldenland Ct

The District is evalua ting shutting down the CO monitor at this site. The District is a federal

attainment area for CO and this monitor is not required. In addition, the District is evaluating the

possibility of shutting down the PM

- 10 SSI as it is not require d

.

The Distri ct is evaluating relocating the Del Paso Manor PM

- 10 TEOM to this site, as it would

free up instrument rack space and rooftop space for NCore instrumentation, etc.

North Highlands

The District is evaluating shutting down the O 3 

### , CO, NO 2 

### , SO 2, 

### and PM

- 10 SSI at this site. This

site is a redundant air monitoring site and was or i ginally sited to support a proposed power plant

project at McClellan AFB . Staff resources used to support this air monitoring site would be

used, in the future, to support the new mandatory NCore monitoring program at Del Paso Manor

and future NO2 near roadway monitoring site s

.

Southern Sacramento County Winter

- time PM2.5 Special Purpose Monitoring Study

The District add ed two additional seasonal PM

- 2.5 E

- BAM's (S pecial P urpose M o nitors ) in the

s outheast quadrant of the District (Sloughhouse and Rancho Seco) during the winter months

(November

- February ) to help support the public notification requirements of the District’s Rule

421

– Mandatory Episodic Curtailment of Wood and Other Solid Fuel Burning. This SPM study

will be conducted during 2008

- 2011.



### 5 .0 Process to review changes to PM

- 2.5 Monitoring Network

40 CFR 58 requires that this Annual Monitoring Plan document how State and Local Agencies

provide for the review of changes to a PM

- 2.5 monitoring network that impact the location of a

violating PM

- 2.5 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

### - 11

-

annual P M

- 2.5 NAAQS as set forth in Appendix N to Part 58 in 40 CFR 58. 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

.

For comparison purposes, the number of PM

- 2.5 monitors by area and population has been

included. The analysis can be found in Appendix A.

The general process for any proposed change to the monitoring network is that the proposed

change is discussed in this Annual Monitoring Plan. Then, during spring, each year, this Annual

Monitoring Plan will be sent by SMAQMD to CARB/TSD for review and comment. Prior to

June 1, each year, this report will be posted to our District Website for no less than 30 day s

, for

public review and comment. During late June, each year, the finalized Annual Monitoring Plan

and comments on the Plan will be forwarded to EPA

- Region IX, prior to the July 1 deadline.



### 6.0 Data Submission Requirements

200 9 Precision/Accuracy reports su bmitted to AQS: Spring 2010

200 9 Annual data certification submitted: June 2010 (by CARB)



### 7 .0 Review of existing SMAQMD /CARB Air Monitoring Sites

For each monitor at each monitoring site, the tables in Appendix B were used to determine if

each monitor me ets 40 CFR 5 8 requirements, including Appendix A (QA Requirements), C

(FRM/FEM/ARM Requirements), D (Network Design Criteria), and E (Probe Sitting Criteria),

when applicable. The SMAQMD ambient air monitoring network meets the requirements of 40

CFR 58 including Appendix A, C, D, and E.

### A PPENDIX A

Comparison of Number of PM2.5 Monitors by Area and Population

The Sacr amento MSA has a total of 1 6 PM2.5 monitors: 5 FRM, 9 BAM, and 2 SASS monitor.

8 of the 1 6 PM2.5 monitors are located in areas of high population density to monitor for

population exposure.

To illustrate how the Sacramento MSA compares to other air distr icts in terms of monitoring

PM2.5, a comparison of the number of PM2.5 monitors by geographic area and population in

several air districts in California is shown in the table below.

San Joaquin

Valley 25,000 3. 9 26 1 per 150,000 1 per 962

The numbers of PM2.5 monitors per person show that the Sacramento MSA has a higher than

average number of monitors per person. The numbers of PM2.5 monitors per squar e mile show

that the Sacramento MSA has a higher than average number of monitors per square mile.

However, caution should be used when doing these types of comparisons, as these four Districts

have different ratios of urbanized area vs. rural areas and ru ral vs. urban population, etc. For

example, Bay Area has a similar size (number of square miles) compared to the Sacramento

MSA, but Bay Area has a higher population density per square mile, in the urbanized areas. San

Joaquin Valley has a highest amount of area, more rural population, and lowest population

density per square mile. In addition, San Joaquin Valley has the typical PM2.5 sources of motor

vehicles and residential wood combustion, but it also has agricultural sources of PM2.5. Thus,

the size of a monitoring network is largely determined by the number of monitors needed to

satisfy the local/regional monitoring needs, depending upon the unique features and needs of that

District.

### B .8 Sloughhouse

The Sloughhouse seasonal (April

- October) O 3 

### monitoring site was established in 1997, to

measure elevated afternoon O 3 

### concentrat ions, under northwesterly winds, in support of the

District's summer O 3 

### Spare the Air program. This special purpose monitoring site measures O 3 

### , Wind Direction, and Wind Speed.

Northwest wind conditions arise when the prevailing southwesterly summer dayt ime sea breeze

becomes weak or non

- existent and the daytime wind flow becomes a northwesterly wind.

Most of our O 3 

### exceedances occur under southwesterly winds. Thus, most of the daily O 3 

### peaks

would occur at Cool, CA or Folsom, CA. If O 3 

### exceedances oc cur under n orthwesterly winds,

then the daily O 3 

### peak tends to occur at Sloughhouse.

Beginning November 2008, seasonal winter monitoring for PM2.5 w as conducted at this site

. PM2.5 data will be collected from November

- March

, during 2009

- 2011, in support of the South

Sacramento County PM2.5 study.

The drip line of a nearby tree, within 10 meters of the O 3 

### inlet, means that this SPM O 3 

### site does

not satisfy Appendix E probe sitting criteria. However, as per 40 CFR 58, "Appendix E

adherence is optional for SPM stations."
