2013 Ambient Air Monitoring Network Plan 1 

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 2012 and proposed network 

modifications for 2013-2014. 

Public Inspection Process

This monitoring network plan was available for public inspection from June 1 to June 30, 2013 

at the AQMD website (www.ourcleanair.com). A hardcopy of the plan was also available at the 

AQMD office.

2013 Ambient Air Monitoring Network Plan 2 

Overview of Washoe County Health District Network Operation

Network Design

The AQMD operated eight (8) ambient air monitoring sites in 2012 (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. Table 1 lists the parameters monitored in 2012 sorted by 

network type and site. 

Figure 1

Washoe County Health District - AQMD Ambient Air Monitoring Sites

 

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.

Notes: Meteorology for the NCore network includes ambient temperature, wind speed, 

wind direction, barometric pressure, relative humidity, and liquid precipitation. The 

PM10 manual method monitor at NCore is for PMcoarse calculation only and is not 

submitted to AQS for data to be used in comparison to the NAAQS. 

Data from the continuous PM2.5 Special Purpose monitor is used for short term air quality 

forecasts and are submitted to AQS with SPM and “non-regulatory” designations.

2013 Ambient Air Monitoring Network Plan 4 

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. The AQMD does not monitor for 

Lead due to there being no sources over 0.5 tons per year and a CBSA population less than 

500,000. Additionally, the AQMD does not monitor for near-road NO2 due to the CBSA 

population size. Tables 2 through 8 provide pollutant specific monitoring requirements. 

Additional pollutant specific data may be found in the “Washoe County, Nevada, Air Quality 

Trends Report, 2003-2012”. The 2012 population data are from the Nevada State 

Demographer’s Office.5

Network Modifications Completed in 2012

The following modifications to the ambient air monitoring network were completed in 2012. 

The AQMD moved offices to Building B in the same complex. As a part of this move, the 

AQMD filter weigh room was relocated as well. The pre and post weighing of filters was not 

disrupted during the move.

Network Modifications Proposed for 2013-2014

The following modifications to the ambient air monitoring network are proposed for 2013-2014. 

SLAMS:

All pollutants and meteorology (Galletti)

• 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 (Galletti)

• Replace the existing PM10 Hi-Volume sampler with a Met One BAM 1020 FEM. 

PM10 (Sparks) 

• Take the existing designated and collocated PM10 Hi-Volume samplers offline. The 

removal of these samplers will complete the change from manual method to a continuous 

sampling frequency for PM10 at all SLAMS sites. 

Meteorology (Toll, So. Reno, Plumb-Kit, Galletti and Sparks)

• Take the existing cup and vane sensors offline and install Met One 50.5H sonic 

anemometers. 

NCore:

Meteorology (Reno3) 

• Install a new Met One 595 solar radiation sensor. 

• Install a new Met One 083E relative humidity sensor. 

• Take the existing Vaisala WXT520 sensor offline and replace with a new Met One 50.5H 

sonic anemometer. 

• Install a new YSI 700 ambient temperature sensor. 

Additional Modifications Proposed for 2013-2014

The following additional modifications are proposed for 2013-2014. 

SLAMS:

All pollutants

• No modifications proposed. 

NCore:

All pollutants

• No modifications proposed. 

Speciation Trends Network: 

All other pollutants and monitoring sites

Data Submission Requirements

Precision and Accuracy Reports for 2012 were submitted to AQS for the: 

 1st quarter in June 2012, 

 2nd quarter in September 2012, 

 3rd quarter in November 2012, and 

 4th quarter in March 2013. 

Annual Data Certification for all data for 2012 was submitted to EPA on April 30, 2013.

2013 Ambient Air Monitoring Network Plan 9 

Overview of Tribal Network Operations

Network Design

Two tribes operate ambient air monitoring networks within the geographic boundaries of 

Washoe County - The Reno-Sparks Indian Colony (RSIC) and Pyramid Lake Paiute Tribe 

(PLPT). Table 9 summarizes the tribal sites and parameters monitored in 2012. Figure 2 shows 

the location of tribal lands for the Reno-Sparks Indian Colony and Figure 3 is a map showing the 

locations of the Pyramid Lake Paiute Tribes’ monitoring sites. For additional detailed site

The Galletti site is located southeast of the Interstate 80 - US Highway 395/Interstate 580 

interchange in a commercial/industrial area. The Galletti site, which monitors PM10 and CO, is 

heavily impacted by on-road vehicle emissions from interstate highways. The site type is to 

determine typical concentrations of CO and PM10.

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 site type is typical 

concentration 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.

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 type is highest 

concentration for CO, PM10 and O3. This site also has a PM2.5 Special Purpose Monitor which 

measures typical concentrations of PM2.5.

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, O3 and PM10 from 

the roadways.
