Overview

The monitoring program of the Nevada Division of Environmental Protection (NDEP) 

operates an ambient air quality monitoring network of gaseous and particulate pollutant 

monitors. The monitors are located in small communities throughout rural Nevada. In the 

metropolitan areas of Reno and Las Vegas; the Washoe County District Health Department, 

Air Quality Management Division and the Clark County Department of Air Quality and 

Environmental Management operate and maintain their respective monitoring networks 

separate from NDEP and submit their Network Plan independently to the United States 

Environmental Protection Agency (USEPA). Also, there are several federally recognized 

tribes that conduct air monitoring within Nevada and submit their own Annual Network Plans 

to the USEPA.

NDEP regulates air quality to protect public health and the environment. Monitoring data is a 

crucial component of regulations used to determine compliance with the USEPA primary and 

secondary air quality standards. Other important uses of these monitors include: support and 

issuance of air quality forecasts, support of long-term health assessments, and tracking longterm air quality both to gauge effectiveness of emission control and abatement strategies and 

to quantify accuracy of ambient pollutant monitoring.

Goals

NDEP created an ambient air quality monitoring program to provide useful and accurate 

information on air quality, which is used to evaluate the success of the State’s air quality 

programs. The Clean Air Act of 1970, and subsequent amendments, defines air quality

standards for various air pollutants necessary to protect the public from injurious pollution 

concentrations. Air pollution concentrations that exceed the National Ambient Air Quality

Standard (NAAQS) can cause a public health hazard, nuisance, annoyance, or damage to 

flora, fauna and personal property. 
2

The NAAQS, published by the USEPA, can be found in 40 Code of Federal Regulations 

(CFR) Part 50, which defines the levels of air quality necessary to protect human health and 

welfare. An area is considered to be in nonattainment for a pollutant if it has violated the 

NAAQS for that pollutant. The CFR includes procedures for evaluating measured air quality 

against the NAAQS. State air quality standards can be found in Nevada Administrative Code 

(NAC) 445B.22097.

Background

The State of Nevada has four jurisdictions which independently manage their own air 

programs as designated by statute: Department of Conservation and Natural Resources 

(DCNR), Division of Environmental Protection (NDEP), Bureau of Air Quality Planning 

(BAQP); Washoe County District Health Department; Air Quality Management Division; 

Clark County Department of Air Quality and Environmental Management and various tribal 

agencies.

State agencies that conduct ambient air monitoring using State and Local Air Monitoring 

Stations (SLAMS) or Special Purpose Monitoring Stations (SPMS), must use Federal 

Reference Methods (FRM) or Federal Equivalent Methods (FEM) that comply with federal 

quality assurance requirements listed in 40 CFR 58, Appendix A. In conjunction with the 

Network Plan, a BAQP quality assurance plan was developed to form the framework for 

planning, implementing, assessing and reporting work performed by the BAQP and for 

implementing quality assurance and quality control protocols.

The Ambient Air Monitoring Program Quality Assurance Project Plan (QAPP) was 

developed to address quality management as well as quality assurance. The QAPP defines the 

policies, procedures, specifications, standards, and documentation necessary to: 1) provide 

data of adequate quality to meet monitoring objectives, and 2) minimize loss of air quality 

data due to malfunctions or out-of-control conditions. As part of the QAPP, the Quality

Management Plan (QMP) describes the organizational structure, functional responsibilities of 

management and staff, lines of authority, and required interfaces between planning, 
3

implementing, assessing and reporting activities involving environmental data operations. 

Both the QAPP and QMP will be updated during this network plan year.

Additionally, the BAQP has developed ambient monitoring guidelines in order to ensure that 

ambient air quality data collected, at regulated facilities in the State, are of the highest quality

and conform to federal requirements for quality assurance listed under 40 CFR 58. 

Ambient air quality monitoring data must be certified on an annual basis as accurate and 

complete. The certification process begins with the complete submittal of all SLAMS data to 

the federal Air Quality System (AQS) for the calendar year. Submittal of data into AQS for 

2012 has been accomplished. Precision and accuracy reports and certification of that data 

should also be submitted within that time frame.

Network Design

With the addition of two new PM2.5 sites for the year 2013, there will be eleven ambient air 

quality monitoring stations in Nevada under the jurisdiction of NDEP. Air quality monitoring 

is represented by ten SLAMS and one SPM. The ozone monitoring conducted by NDEP is 

done on a seasonal basis from April 1st to October 31

st of each year. The EPA’s approval of a 

seasonal ozone monitoring schedule for NDEP is documented in Appendix A. There are three 

meteorological stations, one in Carson City, one in Pahrump and one mobile tower that is 

deployed at various locations within the state. These met stations are used to confirm the 

local meteorological data from the monitoring stations.

In addition to these four independent monitoring networks, air quality monitoring is 

conducted through the Interagency Monitoring of Protected Visual Environments 

(IMPROVE) network by the federal land management agencies. There are two IMPROVE 

monitoring sites in Nevada, at the Jarbidge Wilderness area and Great Basin National Park, 

Lehman Caves. The IMPROVE program is a cooperative measurement effort governed by a 

steering committee composed of representatives from Federal and regional-state 

organizations. The IMPROVE monitoring program was established in 1985 to aid the 

creation of Federal and State implementation plans for the protection of visibility in Class I 
4

areas. In order to meet the site objectives, the IMPROVE site meets the methodologies and 

QA/QC procedures approved by the EPA Regional Administrator. Utilizing the criteria set 

for this Jarbidge site, the NDEP is able to satisfy their regional and transport monitoring 

requirement. According to 40 CFR Part 58 Appendix D 4.7.3, “each state shall install and 

operate at least one PM2.5 site to monitor for regional background and regional transport.” 

Therefore, the NDEP utilizes the Jarbidge site to meet this particular requirement. 

The following table shows the locations and types of monitors operated by NDEP.

Minimum Monitoring Requirements

The USEPA provides minimum site requirements for ozone and particulate matter based on 

metropolitan statistical area (MSA) population. The NDEP’s air monitoring network meets 

or, in most cases, exceeds the minimum network requirements. The monitors currently

required in the NDEP monitoring network by the USEPA are located in Carson City (O3), 

Fallon (O3), Fernley (O3) and Pahrump (PM10). The four PM10 monitoring sites in Pahrump 

are required through a Memorandum of Understanding (MOU) between NDEP, USEPA, Nye

County and the Town of Pahrump. Otherwise, according to 40 CFR Part 58 Appendix D: 

Tables D-4 and D-5; sections 4.2, 4.3.2, 4.3.3, 4.4.2 and 4.5, additional monitoring for criteria 

pollutants is not presently required. However, based on data obtained through special study

monitoring in Carson City and Gardnerville NDEP is establishing a PM2.5 monitoring 

network. These new sites will allow the NDEP to establish credible data to ascertain what the 

PM2.5 conditions are within both areas. Within 3 years, after a valid design value is 

established, the NDEP will evaluate the program and determine if increased PM2.5 monitoring 

is needed within the SPM areas. The following table outlines the minimum required monitors 

within the NDEP ambient air monitoring network.

Table 2: Minimum Monitoring Requirements by Pollutant

*Based on 40 CFR Part 58 Appendix D: Tables D-4 and D-5; sections 4.2, 4.3.2, 4.3.3, 4.4.2 and 4.5, additional monitoring 

for criteria pollutants is not presently required. Additionally, based on the 2008 Lead NAAQS Final Rule, 2010 SO2

NAAQS Final Rule and the 2010 NO2 NAAQS Final Rule, NDEP is not required to monitor for these criteria pollutants. 

Changes in Monitoring Network

Over the last 12 months, as proposed in last year’s plan, two significant impacts and changes 

to the monitoring network are in effect. First, as of April 1st, 2013 the ozone monitor located 

at the Carson City Maintenance yard has been relocated to a comparable vacant lot 2.5 miles 

to the west. This move was necessitated by the city of Carson City re-purposing use of this

location. Based on the weight of the evidence and pursuant to 40 CFR 58.14(c)(6), EPA 

approved the NDEP’s relocation of the SLAMS ozone monitoring at 3300 E. 5th Street to 

2601 S. Carson Street in Carson City (Appendix C). Data collected from the new site will be 

compared to the old site to determine representativeness. Notification of the data collection as 

well as new site information will be created in Air Quality Systems (AQS). Second, the

NDEP decided to create a collocated PM2.5 SLAMS site in Carson City and a SPM site in 

Gardnerville. The decision to create a PM2.5 network was based on the tightening of the PM2.5

NAAQS and the population density of Carson City and Gardnerville. Although Carson City 

and Gardnerville do not meet the CFR requirement for siting a PM2.5 network, the NDEP 

believes it is important to be monitoring these areas to assess possible public health issues.

The USEPA will be notified when data collection and submittal at the new monitoring site is 

commenced. 

In 2011, NDEP was informed that we had to relocate our PM10 monitor located at the Manse 

School in Pahrump due to the school closing. In February 2011, NDEP submitted a letter to 

the EPA requesting approval to relocate the monitor. In March of 2011, NDEP received 

approval to move the existing monitor to the Nye County School District building. However, 

the Pahrump School District found a new use for the school allowing NDEP to remain at the 

existing site. At this time, NDEP will continue to monitor at the Manse School. If needed, 

NDEP has access to the Nye County School District building for our back-up site. 

For this next year, there are no expected changes. Over the next five years, through 2018, 

NDEP will evaluate our current network to determine if any new sites or monitors need to be 

added to the existing monitoring network.

Purpose of Monitors

The purpose of the Nevada Air Monitoring Network is to provide useful and accurate 

information on air quality, which is used to evaluate the success of the State’s air quality 

programs. To accomplish this task, the NAAQS are used to identify the criteria pollutants:

CO (Carbon Monoxide), Pb (Lead), NO2 (Nitrogen Dioxide), O3 (Ozone), particulate matter 

(PM10 and PM2.5), and SO2 (Sulfur Dioxide). Measuring pollutant concentrations in outdoor 

air and comparing the measured concentrations to corresponding standards help to classify

ambient air quality status of an area as either attainment or nonattainment. The NAAQS are

broken down into primary and secondary standards. Primary standards are those established 

to protect public health. Secondary standards are those established to protect the public

welfare from adverse pollution effects on soils, water, vegetation, man-made materials, 
8

animals, weather, visibility, climate, property, and the economy. The scientific criteria upon 

which the standards are based are reviewed periodically by the USEPA, who may reestablish 

or change the standards according to its findings. 

A pollutant measurement that is greater than the ambient air quality standard for its specific 

averaging time is called an exceedance. This is not necessarily a synonym for a violation; for 

each pollutant there are specific rules about how many exceedances are allowed in a given 

time period before a pattern of exceedances is considered to be a violation of the NAAQS. A 

violation may result in regulatory action to clean-up the area’s air. Exceptions are made to 

allow for certain limited exceedances of the standard that may occur, for example, during an 

unusual weather pattern or wildfire (exceptional events). Regulatory action is typically 

reserved for cases where the exceedances are too large or too frequent.

Historically, ambient air quality monitoring by BAQP has looked at trends in air quality to 

aid in the local planning process. Traffic, wood burning stoves, and growth related activities 

have prompted air quality monitoring in specific areas around the State. Data from these sites

has led to public education and outreach to communities identifying the potential health 

effects caused by air pollutants in the environment. Ordinances controlling surface area 

disturbances and other related activities that produce dust have also been implemented with 

the help of the monitoring sites.

Overview of Monitored Parameters

Carbon Monoxide (CO)

CO is a poisonous gas that, when introduced into the bloodstream, inhibits the delivery of 

oxygen to body tissue. The health risk is greatest for individuals with cardiovascular disease.

Ozone (O3)

Ground-level ozone, or photochemical smog, is not emitted into the atmosphere as ozone, but 

rather is formed by the reactions of other pollutants. The primary pollutants entering into this 

reaction, VOCs and oxides of nitrogen, create ozone in the presence of sunlight. Ozone is a 

strong irritant of the upper respiratory system and also causes damage to crops.
9

Particulate Matter (PM10)

Particulate matter with an aerodynamic diameter of 10 microns or less is emitted from 

transportation and industrial sources. Exposure to particle pollution is linked to a variety of 

significant health problems ranging from aggravated asthma to premature death in people 

with heart and lung disease.

Fine Particulate Matter (PM2.5)

Fine particulate matter with a diameter of 2.5 microns or less is created primarily from 

industrial processes and fuel combustion. These particles are breathed deeply into the lungs. 

Exposure to particle pollution is linked to a variety of significant health problems ranging 

from aggravated asthma to premature death in people with heart and lung disease.

Elko: Detailed Site Information

Prior to 1992 the location for this sampler was the fire station at 723 Railroad Street (ID #32-007-003) in a commercial 

area. In November of 1992 this continuous PM10 monitoring site was relocated to the roof of the State offices at 850 Elm 

Street in a predominantly residential area. The monitoring objective was to determine typical concentration/population 

oriented. The manual sampler was replaced with a continuous (TEOM) PM10 monitor in December 1998. In September 

2008, the TEOM monitor was closed and a new BAM 1020 monitor was sited at the Elko Grammar School #2.

Fernley Intermediate School: Detailed Site Information

Ozone monitoring is done at the Fernley Intermediate School which is located at 320 Hardie Lane. This is an area of 

mainly residential and agricultural use. There has recently been a large growth of industry both upwind and downwind of 

this site. Monitoring for PM10 at this site commenced on May 1995, to determine the agricultural and industrial source 

impacts and population exposure. PM10 sampling was discontinued in November 1998. Ozone monitoring began at this 

site July 2007. However, ozone monitoring (SPMS) was previously conducted at the Fernley Volunteer Fire Department 

starting in October 1997 and discontinued on October 2003.

Church: Detailed Site Information

The Church Site began operation in 2004 to complement the existing three other sites in the Pahrump monitoring 

network. Monitoring is accomplished with a continuous beta attenuated monitor located in the southeast corner of the 

Catholic Church. This site represents the southern-most monitoring in Pahrump Valley. The monitoring objective of this 

site is a significant source of PM10. The surrounding area represents residential with little commercial, some native desert 

with a mix of dirt and paved roads.

Manse Elementary: Detailed Site Information

The Manse site represents the monitoring objective for highest concentrations of PM10 in Pahrump. This site replaces the 

Community Pool site, which at the time it was operating, represented the highest concentrations of PM10 in Pahrump. 

Located at 1020 E. Wilson Road, the Manse Elementary site is located on the roof of the school and monitors for PM10

using the continuous beta attenuation monitor. The area adjacent to this site represents mostly commercial, some 

residential, and is adjacent to the busiest activity area of Pahrump. This site is located downwind from residential 

construction developments that have cleared large parcels of ground for building, as well as agricultural areas that 

cultivate large areas of farm-ground and raise livestock. Roads surrounding this site are both paved and dirt.

Glen Oaks: Detailed Site Information

The Willow Creek site was started in 2003 and was located at 1500 Red Butte on the roof of a building in which 

irrigation equipment for the golf course is housed. The monitoring objective of this site was to measure typical 

concentrations/population oriented of PM10 using the beta attenuated monitor. The surrounding area adjacent to this site 

is fairway/golf course and residential structures. Due to closure of the golf course, the Willow Creek site was relocated to 

the Glen Oaks sewer treatment plant in 2009. The Glen Oaks site is a short distance away from the existing golf course 

site and the monitoring objective did not change.

Linda Street: Detailed Site Information

The Linda Street site was started in 2003 and is located at 8825 North Linda Street. The beta attenuated monitor is 

located on the roof of an old railroad box car and represents not only the northern-most site in the Pahrump monitoring 

network, but the most rural area. There is some residential surrounding this site, but mainly native desert vegetation with 

little or no surface disturbances. The monitoring objective for this site is general background levels of PM10 in Pahrump.
