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

years, perform quality assurance activities, and in certain instances, establish NCore sites by 

January

 five 

 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 2010 and proposed network 

modifications for 2011-2012. 

Public Inspection Process

This monitoring network plan was available for public inspection from June 1 to June 30, 2011 

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

available at the AQMD office. Public comments received during the public inspection period 

were submitted along with this plan to EPA Region IX.

Overview of Network Operation 

Network Design

The AQMD operated eight (8) ambient air monitoring sites in 2010 (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 and “attainment/maintenance” for the 8-hour CO NAAQS.2,3 Washoe Cou

classified as “attainment” or “unclassifiable/attainment” for all other pollutants and averaging 

times.

 40 CFR 81.329. 

Washoe County Air Quality Management Division 

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.

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 (2010 for NO2 and CO) or multiple (2008-2010 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, 2001-2010”. The 2009 population data are from the Nevada State 

Demographer’s Office.5

 Ambient air monitoring data from June/July 2008 were influenced by wildfires in Northern California. An 

exceptional events request was submitted to EPA Region IX in October 2009. The design values for O3 and PM2.5

include these data until EPA determines concurrence with the request.

Network Modifications Proposed for 2011-2012

The following modifications to the ambient air monitoring network are proposed for 2011-2012. 

SLAMS:

All pollutants and meteorology (Galletti) 

 Relocate Galletti PM10 monitor to the top of the Galletti shelter. The reason for moving 

this site is because AQMD is on leased Nevada DMV property and has been requested to 

relocate the PM10 monitor due to a parking lot remodel. 

 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. 

NCore:

Meteorology (Reno3) 

 Remove solar radiation sensor from South Reno and install at Reno3. 

 Install new Vaisala WXT520 weather transmitter measuring ambient temperature, wind 

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

Special Purpose Monitor:

PM2.5 (Sparks) 

 Install new Met One BAM 1020 FEM PM2.5 monitor. Continuous PM2.5 data will be 

used for short term air quality forecasts and not be submitted to AQS as data for record. 

PM10 (Sparks) 

 Install new Met One BAM 1020 FEM PM10 monitor. Continuous PM10 data will be used 

for short term air quality forecasts and will not be submitted to AQS as data for record. 

Additional Modifications Proposed for 2011-2012

The following additional modifications are proposed for 2011-2012. 

SLAMS:

Shelter roofs (Toll, South Reno, Plumb-Kit) 

 Install Trex decking and safety railings on top of shelters. 

Data polling (Toll, South Reno, Galletti, Lemmon Valley, Sparks) 

 Install wireless communication instrumentation. 

 Remove all phone lines and modems. 

NCore:

All pollutants 

 No modifications proposed. 

Speciation Trends and Special Purpose Monitor Networks: 

All other pollutants and monitoring sites 

 No modifications proposed.

Review of Changes to PM2.5 Monitoring Network

The geographic area of Washoe County is currently designated as either Attainment or 

Attainment/Unclassifiable for the 24-hour and annual PM2.5 NAAQS. Although the current 

PM2.5 design value (37 g/m3

) violates the 24-hour NAAQS, ambient air monitoring data from 

June/July 2008 were influenced by wildfires in Northern California. An exceptional events 

request was submitted to EPA Region IX in October 2009. The PM2.5 design value includes 

these data until EPA determines concurrence with the request. 

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 2011-2012. 

Data Submission Requirements

Precision and Accuracy Reports for 2010 were submitted to AQS for the: 

 1st quarter in June 2010, 

 2nd quarter in August 2010, 

 3rd quarter in October 2010, and 

 4th quarter in March 2011. 

Annual Data Certification for 2010 was submitted to EPA on April 29, 2011. 
Detailed Site Information 

Galletti

It is located southeast of the Interstate 80 - US Highway 395 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 monitoring objective is to determine 

highest concentrations of PM10 and is population oriented for CO.

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.

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.
