1.0 Introduction

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

required, by Title 40, Code of Federal Regulations, Part 58.10 (40 CFR 58.10), to submit an

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

than July 1st, 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, 2009-December 31, 2009.

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

Sacramento 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 the 

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 Federal Reference Method (FRM), 

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

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

instrumentation being operated, such as Aethalometers and Nephelometers, and surface/upper air 

meteorological sensors required for the PAMS program. The secondary 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.

This report is not an "in depth" analysis of the local air monitoring network 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 incorporation 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, California 

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 25

th

largest MSA in the USA, based upon population, with a population of 2.1 million people1. The 

Sacramento MSA is a non-attainment area for the Federal 8 hr averaged O3 standard and is 

referred to as the Sacramento Federal Nonattainment Area (SFNA). This network plan focuses 

on the monitors 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 2009 prepared by the California Air 

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

Sacramento County is a nonattainment area for the Federal O3 and PM2.5 standards. Sacramento 

County is in attainment for the Federal CO, NO2, and SO2 standards. It has attained the Federal 

PM10 standard but is still designated as non-attainment. Sacramento County is a non-attainment 

area for the California O3, PM-10, and PM-2.5 health standards. The California Air Resources 

Board recommended that EPA designate Sacramento County as unclassified for the 2008 Federal 

Pb standard. Final EPA designations for the 2008 Pb standard are due in November 2010.

The primary focus of the current ambient air monitoring network is the collection of O3 and 

photochemical pollutant precursors such as NOX and VOC, and PM-2.5 data to support SIP 

development, attainment/non-attainment decisions, public notification, and data for air quality 

modeling efforts. Sacramento is one of 26 areas in the USA that are required to operate PAMS. 

Sacramento is one of the 54 areas in the US, with a PM2.5 STN site. The map below identifies 

the locations of current air monitoring stations within Sacramento County, whether they are a 

SLAMS site or not. Table 1 gives the location of each station, AQS ID, pollutants monitored 

and designates whether it is a SLAMS site.

2.1 Monitoring Objectives and Spatial Scales

The basic 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 support 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 welfarebased impacts.

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

representativeness 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 that 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 

objectives and spatial scales.

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

Neighborhood 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 

large 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 for 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. The monitoring network within the MSA exceeds the 

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

Tables 4, 5, 6, and 7.

must be described in the Annual Monitoring Plan, due to EPA, no later than July 1, 2010.
- 9 -

4.0 Recent or Proposed Modifications to the Network

The 2008 revised Pb NAAQS is under review. Once it is finalized, the District will work to meet 

the monitoring requirements as promulgated in the final ruling. A low volume Pb-PM10 sampler 

will be installed, at our Sacramento NCore monitoring site, to satisfy the population-based 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, if the maximum Pb-PM10 threemonth arithmetic mean concentration is greater than or equal to 0.10 ug/m3; (2) the District may

cease operation of the Pb-PM10 sampler when the Pb-TSP sampler becomes operational.

Folsom-Natoma

The District is evaluating adding a CO monitor to this site (see discussion under 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 monitoring site, for this 

MSA. Thus, the District will install a NOy analyzer, SO2 trace level analyzer, a low volume 

PM10 FRM sampler, and a low volume Pb-PM10 at this site, during 2010. The low volume PM10

FRM sampler is needed for the PM10-2.5 (coarse) monitoring, 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 

our 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." Currently, 

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 instrumentation.
- 10 -

The District is evaluating shutting down the two PM related SPM research instruments: 

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

rooftop space for NCore instrumentation.

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, the shelter that houses the CO monitor

has dry rot and would be too costly to repair. The CO monitor is proposed 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. The 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 evaluating 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 required. 

The District 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 O3, CO, NO2, SO2, and PM-10 SSI at this site. This 

site is a redundant air monitoring site and was originally 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 sites.

Southern Sacramento County Winter-time PM2.5 Special Purpose Monitoring Study

The District added two additional seasonal PM-2.5 E-BAM's (Special Purpose Monitors) in the 

southeast 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 PM-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 days, 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

2009 Precision/Accuracy reports submitted to AQS: Spring 2010

2009 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 meets 40 CFR 58 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.

APPENDIX A

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

The Sacramento MSA has a total of 16 PM2.5 monitors: 5 FRM, 9 BAM, and 2 SASS monitor. 

8 of the 16 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 districts 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.

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 square 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 rural 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.2 Elk Grove- Bruceville

The Bruceville air monitoring site has been existence since 1992. It is the upwind O3 and ozone 

precursor monitoring site for our network.

The Bruceville air monitoring site replaced the former Sacramento-Meadowview Rd. O3

monitoring site.

The Bruceville site measures O3, NO2, total NMHC, speciated VOC (episodic only), PM-2.5 

BAM, WD, WS, TMP, RH, SRD, UV Radiation, Precipitation, and Atmospheric pressure

The Bruceville air monitoring site is a PAMS Type 1 site.

Adjacent to the air monitoring site is our Franklin Field- Radar Wind Profiler for measurement 

of Upper level winds and temperature. This Wind profiler is operated year-round. Collection of 

upper air data is a requirement for the PAMS program.

B.3 Sacramento- Del Paso Manor

This site has been in existence since 1979. This air monitoring site is the largest air monitoring 

site in the Sacramento Valley air basin. This site may be one of the largest air monitoring sites in 

Northern California, in terms of number of parameters measured.

It measures O3, CO, NO2, SO2, NMHC, speciated VOC (C2-C12), Carbonyl, PM-10 (SSI- main 

and collocated), PM-10 TEOM, PM-2.5 FRM (main and collocated), PM-2.5 BAM, Speciated 

PM-2.5 (SASS), Black Carbon (Aethalometer), Scattering Coefficient (Nephelometer), WDresultant, WS-resultant, ambient temperature, relative humidity, and total solar radiation. 

This site is a PAMS Type 2 primary site and a PM-2.5 Speciation Trend Network (STN) site. 

This site is the current PM-2.5 design value site for this MSA.

In October 2009, EPA- Region IX approved this monitoring site as an NCore site. This is one of 

six NCore sites proposed for California. The District plans to operate an NCore site at Del Paso 

Manor, no later than January 1, 2011.

To accommodate the NCore monitoring instrumentation, the District will expand the size of the 

existing roof deck, add a 10 meter NOY converter tower, and upgrade the electrical capacity in 

Spring 2010.

B.8 Sloughhouse

The Sloughhouse seasonal (April-October) O3 monitoring site was established in 1997, to 

measure elevated afternoon O3 concentrations, under northwesterly winds, in support of the 

District's summer O3 Spare the Air program. This special purpose monitoring site measures O3, 

Wind Direction, and Wind Speed.

Northwest wind conditions arise when the prevailing southwesterly summer daytime sea breeze 

becomes weak or non-existent and the daytime wind flow becomes a northwesterly wind. 

Most of our O3 exceedances occur under southwesterly winds. Thus, most of the daily O3 peaks 

would occur at Cool, CA or Folsom, CA. If O3 exceedances occur under northwesterly winds, 

then the daily O3 peak tends to occur at Sloughhouse.

Beginning November 2008, seasonal winter monitoring for PM2.5 was 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 O3 inlet, means that this SPM O3 site does 

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

adherence is optional for SPM stations."
