Introduction

Purpose

The U.S. Environmental Protection Agency (EPA) finalized amendments to the ambient air 

monitoring regulations on October 17, 2006.1 The amendments revise the technical 

requirements for certain types of ambient air monitoring sites, add provisions for monitoring of 

PMcoarse, and reduce certain monitoring requirements for criteria pollutants. Monitoring agencies 

are required to submit annual monitoring network plans, conduct network assessments every five 

years, perform quality assurance activities, and in certain instances, have NCore sites established

by January 1, 2011. 

This plan was prepared and submitted as part of the fulfillment to these new regulations. It 

represents the Washoe County Health District - Air Quality Management Division’s (AQMD) 

ambient air monitoring program activities completed in 2011 and proposed network 

modifications for 2012-2013. 

Public Inspection Process

This monitoring network plan was available for public inspection from June 1 to June 30, 2012

at the AQMD website (www.washoecounty.us/health). A hardcopy of the plan was also 

available at the AQMD office.

Overview of Network Operation

Network Design

The AQMD operated eight (8) ambient air monitoring sites in 2011 (Figure 1). The red 

boundary delineates Hydrographic Area 87 (HA 87) as defined by the State of Nevada Division 

of Water Resources and is currently designated as “serious” non-attainment for the 24-hour PM10

NAAQS.2,3 Washoe County is classified as “attainment” or “unclassifiable/attainment” for all 

other pollutants and averaging times.

Figure 1

Washoe County AQMD Ambient Air Monitoring Sites

Table 1 lists the parameters monitored in 2011 sorted by network type and site.

 2 40 CFR 81.329.

3 In July 2009, the AQMD submitted a SIP revision to EPA requesting redesignation of HA 87 to an 

attainment/maintenance area for the 24-hour PM10 NAAQS. On April 19, 2011, EPA published a final rule (76 FR 

21807) finding that 1) the Truckee Meadows failed to attain the NAAQS by the applicable date and 2) the Truckee 

Meadows is currently attaining the NAAQS based on recent monitoring data (2007-2009). The rule does not change 

the “Serious” non-attainment designation.

Data from the continuous PM2.5 and PM10 Special Purpose monitors are used for short 

term air quality forecasts and are submitted to AQS with SPM and “non-regulatory” 

designations.

Minimum Monitoring Requirements

The AQMD’s ambient air monitoring network meets the minimum monitoring requirements for 

all criteria pollutants pursuant to 40 CFR 58, Appendix D. Tables 2 through 6 provide pollutant 

specific monitoring requirements. The design values are based on ambient air monitoring data 

for single (2011 for NO2, CO, and SO2) or multiple (2009-2011 for O3, PM2.5, and PM10) years. 

Additional pollutant specific design value data may be found in the “Washoe County, Nevada, 

Air Quality Trends Report, 2002-2011”. The 2011 population data are from the Nevada State 

Demographer’s Office.5

Network Modifications Proposed for 2012-2013

The AQMD will be moving offices from our current location to Building B in the same complex. 

As a part of this move, the AQMD filter weigh room will be relocated as well. We anticipate the 

move to be complete in the summer of 2012. 

The following modifications to the ambient air monitoring network are proposed for 2012-2013.

SLAMS:

All pollutants and meteorology (Galletti)

• Take the existing PM10 Hi-Volume sampler offline and replace it with the Met One BAM 

1020 FEM PM10 monitor from the So. Reno site.

• Relocate entire Galletti monitoring site approximately 45 meters to the north of its 

current location. The reason for relocating this site is to move the shelter away from trees 

that are less than 5 meters from the shelter.

PM10 (So. Reno)

• Remove the Met One BAM 1020 FEM PM10 monitor and install at Galletti.

NCore:

Meteorology (Reno3)

Review of Changes to PM2.5 Monitoring Network

In the event that a review of changes to the PM2.5 monitoring network is required, the annual 

network plan and five year network assessment would be used to provide for this review. No 

changes are proposed to the PM2.5 monitoring network for 2012-2013.

Data Submission Requirements

Precision and Accuracy Reports for 2011 were submitted to AQS for the:

1st quarter in June 2011,

Incline

This site is located at the Washoe County Service Center at 855 Alder Avenue and is outside HA 

87. It is located in a residential/commercial neighborhood, where the monitoring objective is 

population oriented for O3. The AQMD had monitored PM10 (1993-2002) and CO (1993-2002) 

and currently monitors for O3. This site was temporarily closed from December 2005 to May 

2008 for remodeling. By multi-agency cooperative agreement, the California Air Resources 

Board (CARB) monitored PM2.5 (1999-2002) and NO2 (1999-2002). Since May 2008 this site 

only monitors for O3.

Reno3

This downtown site began operation in January 2002 to replace the Reno site. Both a residential 

neighborhood and a commercial growth area surround this site. As of December 2010 this site 

became an NCore site. The pollutants measured are PM10, PM2.5, PMcoarse, O3, Trace CO, Trace 

SO2 and Trace NOy, and NO2. The monitoring objectives follow those set forth by EPA for an 

NCore site.

Sparks

The Sparks site is located on US Postal Service property at 750 Fourth Street. The site is 

surrounded by commercial property, a residential neighborhood and is adjacent to Dilworth 

Middle School. In 2007 the Sparks site was moved approximately 55 meters north of its 

previous location, due to tree growth affecting siting criteria. The site has a population oriented 

monitoring objective for the monitoring of O3 and PM10 and highest concentration for CO.

Toll

The Toll Road site is located at 684A State Route 341 (Geiger Grade), one-half mile east of US 

Highway 395. The site is near the edge of a residential neighborhood and adjacent to an area 

that may become commercially developed. Due to the distance from the probe to the nearest 

roadway, this is a middle scale site. This site monitors source impacts of CO and PM10 from the 

roadways and highest concentrations of O3.
