### 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 independentl y to the United States Environmental Protection Agency (US EPA)
. 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 comp onent 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 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 C lean Air Act of 1970 , and subsequent amendments , defines air quality standards for various air pollutants necessary to protect the public from injurious p ollution concentrations. Air pollution concentrations that exceed the National Ambient Air Quality Standard (NAAQS) can cause a public health hazard, nuisance, anno yan ce, or damage to flora, fauna and personal property.2

The NAAQS, published by the US EPA, 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 pol lutant. 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. 

### Back**ground**
The State of Nevada has four jurisdictions which independentl y manage their own air programs as designated by s tatute : 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 Manag ement 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. Inconjunction with the Network Plan, a BAQP quality assurance plan was developed to form the framework for planning, implementing, assessing and reporting work performed b y the BAQP and for implementing quality

assurance and quality control protocols
. The Ambient Air Monitoring Program Quality Assurance Project Plan (QAPP) wa s 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 high est quality and conform to federal requirements for quality assurance listed under 40 CFR 58. Ambient air quality

monitoring data must be certi fied 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

S ys tem (AQS) for the calendar year. Submittal of data into AQS for 20 12 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 PM 2.5 sites for the year 2013, there will be eleven ambient air quality monitoring stations in Nev ada 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 1 st to October 3 1 st of each ye ar. 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 lo cal 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 b y 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 b y 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 I4

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 PM 2.5 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 typ es of monitors operated b y 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 b y the USEPA are located in Carson City (O 3 ), Fallon (O 3 ), Fernley

(O 3 ) and Pahrump (PM 10 ). The four PM 10 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 PM 2.5 monitoring network. These new sites will allow the NDEP to establish credible data to asc ertain what the PM 2.5 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 PM 2.5 monitoring is needed within the SPM areas
. The following table outlines the minimum required monitors within the NDEP ambient air monitoring network
.

*B ased 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 SO 2 NAAQS Final Rule and the 2010 NO 2 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, a s of April 1 st , 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 b y 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. 5 th 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 S ys tems (AQS). Second, the **Pollutant Minim** **um**

NDEP decided to create a collocated PM 2.5 SLAMS site in Carson City and a SPM site in Gardnerville. The decision to create a PM 2.5 network was based on the tightening of the PM 2.5 NAAQS and the population density of Carson City

and Gardnerville
. Although Carson City and Gardnerville do not meet the CFR requirement for siting a PM 2.5 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 PM 10 monitor located at the Manse School in Pahrump due to the school clos ing. 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 ye ars, through 201 8 , 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) , NO 2 (Nitrogen Dioxide) , O 3 (Ozone) , particulate matter (PM 10 and PM 2.5 ), and SO 2 (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 establi shed 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 s ynonymfor 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 ty

picall y reserved for cases where the exceedances are too large or too frequent. Historically, ambient air quality monitoring b y 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 Sta te. Data from these sites has led to public education and outreach to communities identifying the potential health effects caused b y 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 (O** 3 **)** Ground

- level ozone , or photochemical smog, is not emitted into the atmosphere as ozone, but rather is formed b y 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 s ys tem and also causes damage to crops.9

**Particulate Matter (PM** 10**)** 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. **Fin e Particulate Matter (PM** 2.5 **)** 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.10

### Elk**o: 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 PM 10 mo nitoring site was re located to the roof of the State offices at 850 Elm Street in a predominantly residential area. The monitoring objective wa s to determine typical concentration/population oriented. The manual sampler was replaced with a continuous (TEOM) PM 10 mo nitor in December 199 8. 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** O zone 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 dow nwind of this site. Monitoring for PM 10 at this site commenced on May 1995, to determine the agricultural and industrial source im pacts and population exposure. PM 10 sampling was discontinued in November 1998. O zone monitoring began at this site July 2007. However, o zone monitoring (SPMS) was previously conducted at the Fernley Volunteer Fire Department starting in October 1997 and discontinued on October 2003.

### Glen Oak**s :**  **Detailed Site Information**  The Willow

Creek site was started in 2003 and wa s 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 PM 10 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 wa s relocated to the Glen Oaks sewer treatment plant in 2009. The Glen Oaks site is a short distance away from the existing go lf course site and the monitoring objective did not change
