### 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 Q uality Management Division and the Clark County Department of Air Q uality 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 (US EPA )

. A lso, 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 tracki ng 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

inform ation 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, annoyance, 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.



### Background

The State of Nevad a has four jurisdictions which independently 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 r equirements listed in 40 CFR 58 , Appendix A. In conjunction with the

Network Plan, a BAQP quality assurance plan was d eveloped 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) 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, t he 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 ce rti 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 ystem (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, t here 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 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

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 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 represe ntatives 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 objec tives, the IMPROVE site meets the methodologies and

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

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

requirement. According t o 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.

T he following table shows the locations and typ es 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 (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 criter ia

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 cond itions 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 t he minimum required monitors

with in 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 SO 2 NAAQS Final Rule and the 2010 NO 2 NAAQS Final Rule, NDEP is not required to monitor for these criteria pollut ants.



### 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 t he 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

appro ved 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. N otification of the data collection as

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

NDEP decided to create a collocated PM 2.5 SLAMS site in Carson City a nd 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, t he NDEP

believes it is important to be monitoring these areas t o 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

. I n March of 2011, NDEP received

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

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

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

NDEP has access to the Nye County School District building for our back

- up site.

Fo r th is next year, there are no expected changes

. Over the next five years, 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 (L ead ) , 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 per iodically by the USEPA, wh o 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 t o 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) . R egulatory 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 Sta te. 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 produ ce 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 by the reactions of other pollutants. The primary pollutants entering in to 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 (PM 10 )

Particulate matter with a n 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 peo ple with heart and lung disease.10

### 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 t his continuous PM 10 monitoring site was re located 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) PM 10 monitor 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

### 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 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, t he 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 go lf course site and the monitoring objective did not change
