### 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 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 agencie s 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 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 C lean 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 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 quality

necessary to protect human health and welfare. An area is considered to be in nonattainment for2

a pollutant if it has violated the NAAQS for that pollutant. The CFR includes pr ocedures 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 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 developed to form the framework for planning, implementing,

assessing and repor ting 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 Q APP 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, 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 activiti es 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 tha t

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 basi s 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. The 201 3 data was submitted for

certification in April , 201 4 and the 201 4 data will b e submitted by May 1, 201 5

. Submittal of

precision and accuracy data into AQS for 20 1 3 was accomplished on January

, 20 1 4

. Submittal

of precision and accuracy data into AQS for calendar year 201 4 was accomplished by January

,

201 5

.



### 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

- BAQP 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. 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 S tate

. These met eorological stations are used to confirm the local meteorologic al 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 comp osed 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 o rder 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 ab le 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 one PM 2.5 site to monitor for regional background and regional

transport.” T he NDEP

- BAQ P 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. 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 n etwork

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 the NDEP, USEPA, Nye County and the Town of Pahru mp.

A ccording 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 b ased on the 20 10 Revisions to Lead Ambient Air Monitoring Requirements (75 FR

81126 (Dec. 27, 2010)) , 2010 SO 2 NAAQS Final Rule (75 FR 35520 (June 22, 2010)) , and the

2010 NO 2 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 SO 2 emissions for

each county, the calculated P opulation W eighted E mission I ndex ( PWEI ) ( b ased on the proposed

data requirement rule) does not warrant any SO 2 monitoring in the NDEP ’s jurisdiction

. Changes

to the proposed rule may change NDEP

- BAQP’s requirement for SO 2 monitoring.

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

generally so low in the 15 r ural c ounties ( with in the NDEP

- BAQP’s jur isdiction ) that monitoring

for Pb is not necessary. I n 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 ru ral c ounties

, 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

.

B ased 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 da ta to ascertain PM 2.5 cond itions within both areas. By the end of

2016

, a valid design value will be available. T he NDEP

- BAQP will continue to evaluate the

program and determine if increased PM 2.5 monitoring is needed within the SPM S 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 mon itors for

the well

- being of the public’s health. The following table outlines the monitors with in 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 monit oring 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,

o ver 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 monitorin g 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 1 st , 2015.



### Purpose of Monitors

The purpose of the Nevada Air Monitoring Network is to pr ovide 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 st andards , 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, wh ich 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 N AAQS

. A10

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 pat tern 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 at trends in air

quality to aid in the local planning proces s. 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 effect s 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 (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 the

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 diameter 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 heart 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 health11

problems ranging from aggravated asthma to premature death in peo ple with heart and lung

disease.12

### Elko: Detailed Site Information

Prior to 1992

, the location for this sampler was the fire station at 723 Railroad Street (ID #32

- 007

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 sa mpler 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 t he 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
