Overview

The monitoring program of the Nevada Division of Environmental Protection Bureau of Air 

Quality Planning (NDEP-BAQP) 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 the NDEP-BAQP. Those agencies submit their Network Plans

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.

The NDEP Bureaus of Air Quality Planning and Air Pollution Control regulate 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 long-term air quality both to gauge 

effectiveness of emission control and abatement strategies and to quantify accuracy of ambient 

pollutant monitoring.

Goals

The NDEP-BAQP 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 require the USEPA to define 

national ambient air quality standards (NAAQS) for various air pollutants necessary to protect 

the public from injurious pollution concentrations. Air pollution concentrations that exceed the 

NAAQS can cause a public health hazard, or cause damage to flora, fauna and personal property. 

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

Regulations (CFR) Part 50. The NAAQS for each pollutant defines the levels of air quality 

necessary to protect human health and welfare. An area is considered to be in nonattainment for 
2

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 that independently manage their own air programs as 

designated by statute: Department of Conservation and Natural Resources (DCNR), NDEPBAQP; 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. Along with 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, implementing, assessing and 

reporting activities involving environmental data operations. The QAPP and the QMP have been 

submitted to the USEPA for approval. The QMP was approved by USEPA on April 20, 2015. 

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. 
3

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. The 2013 data was submitted for 

certification in April, 2014 and the 2014 data will be submitted by May 1, 2015. Submittal of 

precision and accuracy data into AQS for 2013 was accomplished on January, 2014. Submittal 

of precision and accuracy data into AQS for calendar year 2014 was accomplished by January, 

2015.

Network Design

Air quality monitoring is represented by ten SLAMS and one SPMS for a total of eleven ambient 

air quality monitoring stations in Nevada under the jurisdiction of the NDEP-BAQP. The ozone 

monitoring conducted by the NDEP-BAQP is done on a seasonal basis from April 1st to October 

31

st of each year. The USEPA’s approval of a seasonal ozone monitoring schedule for the NDEP 

is documented in Appendix A. However, NDEP-BAQP will change to a year-around monitoring 

schedule for Ozone beginning in April of 2015. 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 meteorological stations are used to confirm the local meteorological data from 

the monitoring stations.

In addition to the 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. 

One is at the Jarbidge Wilderness area and the other is at 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 in the creation of state and federal

implementation plans for the protection of visibility in federal Class I areas. In order to meet the 

site objectives, the IMPROVE site must meet the methodologies and quality assurance and 

quality control (QA/QC) procedures approved by the USEPA Regional Administrator. Utilizing 

the criteria set for the Jarbidge site, the NDEP-BAQP is able to satisfy the USEPA’s regional and 

transport monitoring requirements. According to 40 CFR Part 58 Appendix D 4.7.3, “each state 
4

shall install and operate at least one PM2.5 site to monitor for regional background and regional 

transport.” The NDEP-BAQP utilizes the Jarbidge site to meet this particular requirement.

Minimum Monitoring Requirements

The USEPA provides minimum site requirements to monitor for ozone (O3) and particulate 

matter (PM) based on metropolitan statistical area (MSA) population. 40 CFR Part 58, Appendix 

D. The NDEP-BAQP’s air monitoring network meets or, in most cases, exceeds the minimum 

network requirements. The monitors currently required in the NDEP-BAQP 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 the NDEP, USEPA, Nye County and the Town of Pahrump. 

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,

4.5, and based on the 2010 Revisions to Lead Ambient Air Monitoring Requirements (75 FR 

81126 (Dec. 27, 2010)), 2010 SO2 NAAQS Final Rule (75 FR 35520 (June 22, 2010)), and the 

2010 NO2 NAAQS Final Rule (75 FR 6474, 6502-6517 (Feb. 9, 2010), as revised by 78 FR 

16184 (Mar. 14, 2013), the NDEP-BAQP is not required to have additional monitoring for these 

criteria pollutants. Based on the latest Census Bureau population estimates and SO2 emissions for 

each county, the calculated Population Weighted Emission Index (PWEI) (based on the proposed 

data requirement rule) does not warrant any SO2 monitoring in the NDEP’s jurisdiction. Changes 

to the proposed rule may change NDEP-BAQP’s requirement for SO2 monitoring.

As a result of the elimination of lead (Pb) from gasoline, Pb concentrations in the ambient air are 

generally so low in the 15 rural counties (within the NDEP-BAQP’s jurisdiction) that monitoring 

for Pb is not necessary. In addition, the revised monitoring requirements for the Pb NAAQS now 

require Pb monitoring near sources such as industrial facilities that emit one-half ton or more of 

Pb per year and at NCORE sites in Core Based Statistical Areas (CBSA) with populations greater 

than 500,000. 75 FR 81126 (Dec. 27, 2010). In Nevada’s 15 rural counties, there are no sources 

that emit one-half ton or more of Pb per year and no CBSAs with populations greater than 

500,000. NDEP discontinued monitoring for Pb in 1990.

Based on data obtained through special study monitoring in Carson City and Gardnerville, the

NDEP-BAQP has established a PM2.5 monitoring network. These sites will allow the NDEPBAQP to establish credible data to ascertain PM2.5 conditions within both areas. By the end of 

2016, a valid design value will be available. The NDEP-BAQP will continue to evaluate the 

program and determine if increased PM2.5 monitoring is needed within the SPMS areas.
7

Based on 40 CFR 58 Appendix D, the NDEP-BAQP understands that it is not required to have 

certain monitors (PM10, PM2.5) in the network. However, based on preliminary data from the 

various monitoring sites, the NDEP-BAQP believes that it is important to have these monitors for 

the well-being of the public’s health. The following table outlines the monitors within the NDEP 

ambient air monitoring network.

Changes in Monitoring Network

After careful review of our monitoring network, NDEP-BAQP will be changing from seasonal 

Ozone monitoring to year-around monitoring. This will allow for better understanding of our 

Ozone challenges within the state. This change will take affect beginning in April 2015. Also, 

over the next five years (as part of the 5-year Network Assessment), the NDEP-BAQP will 

evaluate the current network to determine if any new sites or monitors are required to be added to 

the existing monitoring network. In the event that a review of changes to the monitoring network 

were required, the annual network plan and five year network assessment would be used to 

provide for this review. The 5-year Network Assessment is due July 1st, 2015.

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 NDEP-BAQP utilizes the NAAQS for each criteria 

pollutant set forth in the Clean Air Act: Carbon Monoxide (CO), Lead (Pb), Nitrogen Dioxide

(NO2), Ozone (O3), coarse and fine particulate matter (PM10 and PM2.5), and Sulfur Dioxide

(SO2). By measuring pollutant concentrations in outdoor air and comparing the measured 

concentrations to corresponding standards, the NDEP-BAQP is able to identify the 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, 

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

which the standards are based are reviewed periodically by the USEPA, which 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. An exceedance is not necessarily 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 
10

violation may result in regulatory action to improve the air quality in that area. Exceptions are 

made to allow for certain limited exceedances of the standard that may occur, for example, 

during exceptional events, such as an unusual weather pattern or wildfire. Regulatory action is 

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

Historically, ambient air quality monitoring by the NDEP-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 have also been developed 

and implemented to help control surface area disturbances and other related activities that 

produce dust.

Overview of Monitored Parameters

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, volatile organic compounds (VOCs) and oxides of nitrogen, create ozone in the 

presence of sunlight. According to the USEPA, ozone is a strong irritant of the upper respiratory 

system and also causes damage to crops.

Particulate Matter (PM10)

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

transportation and industrial sources. According to the USEPA, 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. According to the USEPA, these particles are breathed deeply 

into the lungs. Exposure to fine particle pollution is linked to a variety of significant health 
11

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 Tapered Element Oscillating 

Microbalance (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 in July 2007. However, ozone monitoring (SPMS) was previously conducted at the 

Fernley Volunteer Fire Department starting in October 1997 and discontinued in 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 location in Pahrump Valley. The monitoring 

objective of this site is a significant source of PM10. The surrounding area is characterized by residential use with 

little commercial use, as well as some native desert with a mix of dirt and paved roads.

Manse Elementary: Detailed Site Information

The Manse site represents the monitoring objective for the 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 is characterized by

mostly commercial use with some residential use, 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

Monitoring began at the Willow Creek site in 2003. The monitor was located at 1500 Red Butte on the roof of a 

building in which irrigation equipment for a golf course was housed. The monitoring objective of this site was to 

measure typical concentrations/population oriented of PM10 using the beta attenuation monitor. The surrounding 

area adjacent to this site was fairway/golf course and residential structures. Due to closure of the golf course, the 

Willow Creek site was relocated to the Glen Oaks sewage 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

Monitoring at the Linda Street site was started in 2003. The site is located at 8825 North Linda Street. The beta 

attenuation 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 upwind

background levels of PM10 in Pahrump.
