### Overview

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

Quality Planning (NDEP

- BAQP ) operates an ambient air quality monitorin g 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 the NDEP

- BAQP . Those agencies submit their Network Plan s

independently 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.

The NDEP Bureaus of Air Quality Planning and Air Pollution Control regulate a ir 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 C lean Air Act of 1970

, and subsequent amendments

, req uires 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 hazar d, or cause damage to flora, fauna and

personal property.

The NAAQS, published by the US EPA, 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 quality2

necessary to protect h uman 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 Nevad a has four jurisdictions that independently manage their own air programs as

designated by s tatute : Department of Conservation and Natural Resources (DCNR), NDEP

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 Moni toring 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 wit h 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 Moni toring 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, t he 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 environme ntal 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 58.3

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

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

federal Air Quality S ystem (AQS) for the calendar year. The 2012 data was submitted for

certification on March 28, 2013 and the 2013 data was submitted on May 1, 2014. Submittal of

precision and accuracy data int o AQS for 20 1 2 was accomplished on January 4, 20 13

. Submittal

of precision and accuracy data into AQS for calendar year 2013 was accomplished by January

14 , 2014

.



### Network Design

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

air quality monitoring station s in Nevada under the jurisdiction of the NDEP

- BAQP

. The ozone

monitoring conducted by the NDEP is done on a seasonal basis from April 1 st to October 3 1 st of

each year. The US EPA’s approval of a seasonal ozone monitoring schedule for the 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 S tate

. The se

met eorological 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

.

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 f ederal and regional

- state organizations. The

IMPROVE monitoring program was established in 1985 to aid in the creation of s tate 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 t he US EPA Regional Administrator. Utilizing

the criteria set for th e Jarbidge site, the NDEP

- BAQP is able to satisfy the USEPA’s regional and

tra nsport monitoring requirement s

. According to 40 CFR Part 58 Appendix D 4.7.3, “each state4

shall install and operate at least on e PM 2.5 site to monitor for regional background and regional

transport.” T he NDEP

- BAQP utilizes the Jarbidge site to meet this particular requirement.5

T he following table shows the locations and typ es of monitors operated by NDEP.

### Minimum Monitoring Requirements

The USEPA provides minimum site requirements to monitor for ozone (O 3 ) and particulate

matter (PM) based on metropolitan statistical area (MSA) population. 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 (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 U nderstanding (MOU) between the

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 presentl y required. However, based on data obtained

through special study monitoring in Carson City and Gardnerville , the NDEP

- BAQP has

establish ed a PM 2.5 monitoring network. These sites will allow the NDEP

- BAQP to establish

credible data to ascertain PM 2.5 con d itions within both areas. Within three years, after a valid

design value is established, the NDEP

- BAQP will evaluate the program and determine if

increased PM 2.5 monitoring is needed within the SPM S areas

. The following table outlines the

minimum required monitors with in the NDEP ambient air monitoring network

### Changes in Monitoring Network

In 2011, the NDEP

- BAQP was informed that it had to relocate the PM 10 monitor located at the

Manse School in Pahrump due to the school clos ing. In February 2011, the NDEP

- BAQP

submitted a letter to the US EPA requesting approval to relocate the monitor , which approval was

received in March of 2011 to move the existing monitor to the Nye Co unty School District

building. However, the Pahrump School District found a new use f or the school

, allowing the

NDEP

- BAQP’s monitor t o remain at the existing site. At this time, the NDEP

- BAQP will

continue to monito r at the Manse School. If needed, the NDEP

- BAQP has access to the Nye

County School District building as a back

- up site.

T he monitoring start date for both PM 2.5 monitors at the Carson Armory site was entered

incorrectly in last year’s annual network plan. The corrected monitoring start date has been

changed from March 1, 2013 to April 1, 2013

. There are no further expect ed changes f or th is

next year

. Over the next five years, through 201 9

, 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 PM 2.5 monitoring network were

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

this review. N o changes are proposed for the PM 2.5 monitoring network for 2013

- 2014.



### 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 )

, L ead (Pb )

, Nitrogen Dioxide

( NO 2 )

, Ozone ( O 3 )

, coarse and fine particulate matter (PM 10 and PM 2.5 ), and Sulfur Dioxide

( SO 2 ). By m easuring 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 sta ndards. Primary standards are

those established to protect public health. Secondary standards are those established to protect9

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, wh ich may reestablish or

change the standards according to its findings.

A pollutant measurement that is greater tha n 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 exceptional

events, such as an unusual weather pattern or wildfire

. R egulatory 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 a t 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 outre ach 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

.



### Overv iew 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. According to the USEPA, t he 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 into this

reaction, volatile organic compounds ( VOCs ) and oxides of nitrogen, create ozone in the10

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

system and also causes damage to crops.

Particulate Matter (PM 10 )

Particulate matter with a n aerodynamic diamet er of 10 microns or less is emitted from

transportation and industrial sources. According to the USEPA, e xposure to particle pollution is

linked to a variety of significant health problems ranging from aggravated asthma to premature

death in people with h eart and lung disease.

Fine 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. According to the USEPA, t hese particles are breathed deeply

into the lungs. Exposure to fine 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.11

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 orient ed . The manual samp ler was replaced with a continuous Tapered Element Oscillating

Microbalance (TEOM) PM 10 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

### Glen Oaks : Detailed Site Information

Monitoring began at t he 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 PM 10 using the beta attenuat ion monitor. The surrounding area adjacent to this site was fairway/golf course and residential structures. Due to closure of the golf course, t he

Willow Creek site was relocated to the Glen Oaks sew age 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
