20 12 Ambient Air Monitoring Network Plan

# Introduction

Purpose

The U.S. Environmental Protection Agency (EPA) finalized amendments to the ambient air

monitoring regulations on October 17, 2006. 1 

### The amendments revise the technical

requirements for certain types of ambient air monitoring sites, add provisions for monitoring of

PM

coarse 

### , and reduce certain monitoring requirements for criteria pollutants. Monitoring agencies

are required to submit annual monitoring network plans, conduct network assessments every five

years, perform quality assura nce activities, and in certain instances, have NCore sites establish ed

by January 1, 2011.

This plan was prepared and submitted as part of the fulfillment to these new regulations. It

represents the Washoe County Health District

- Air Quality Management Division’s (AQMD)

ambient air monitoring program activities completed in 20 1 1 and proposed network

modifications for 201 2

- 201 3

.

Public Inspection Process

This monitoring network plan was available for public inspection from June 1 to June 30, 201 2

at the AQMD website ( www.washoecounty.us/health ). A hardcopy of the plan was also

available at the AQMD office

.

# Overview of Network Operation

Network Design

The AQMD operated eight (8) ambient air monitoring sites i n 20 1 1 (Figure 1). The red

boundary delineates Hydrographic Area 87 (HA 87) as def ined by the State of Nevada Division

of Water Resources and is currently designated as “serious” non

- attainment for the 24

- hour PM 10 

### NAAQS. 2

, 3 

### Washoe County is classified as “attainment” or “unclassifiable/attainment” for all

other pollutants and averagin g times.

Figure 1

Washoe County AQMD Ambient Air Monitoring Sites

Table 1 lists the parameters monitored in 20 1 1 sorted by network type and site

.

2 40 CFR 81.329.

3 In July 2009, the AQMD submitted a SIP revision to EPA requesting redesignation of HA 87 to an

attainment/maintenance area for the 24

- hour PM 10 NAAQS. On April 19, 2011, EPA published a final rule (76 FR

21807) finding that 1) the Truckee Meadows failed to attain the NAAQS by the applicable date and 2) the Truckee

Meadows is currently attaining the NAAQS based on recent monitoring data (2007

- 200 9). The rule does not change

the “Serious” non

- attainment designation.

20 12 Ambient Air Monitoring Network Plan

4 Minimum Monitoring Requirements

The AQMD’s ambient air monitoring network meets the minimum monitoring requirements for

all criteria pollutants pursuant to 40 CFR 58

, Appendix D

. Tables 2 through 6 provide pollutant

specific monitoring requirements

. The design values are based on ambient air monitoring data

for single ( 20 1 1 for NO 2 

### , CO , and SO 2 

### ) or multiple ( 200 9

- 20 1 1 for O 3 

### , PM 2.5 

### , and PM 10 

### ) years.

Additional pollutant specific design value data may be found in the “ Washoe County, Nevada,

Air Quality Trends Report, 2002

- 2011”

. The 20 1 1 population data are from the Nevada State

Demographer’s Office. 5

It is located southeast of the Interstate 80

- US Highway 395 interchange in a

commercial/industrial area. The Galletti site, which monitors PM 10 

### and CO, is heavily impacted

by on

- road vehicle emissions from interstate highways. The monitoring objective is to determine

highest concentrations of PM 10 

### and is population oriented for CO

36 Toll

The Toll Road site is located at 684A State Route 341 (Geiger Grade), one

- half mile east of US

Highway 395. The site is near the edge of a residential neighborhood and adjacent to an area

that may become commercially developed. Due to the distance from the probe to the nearest

roadway, this is a middle scale site . This site monitors source impacts of CO and PM 10 

### from the

roadways and highest concentrations of O 3

* Trees are not of sufficient height and leaf canopy density to interfere with the normal unrestricted airflow around

the monitoring path. At least 90 percent of the monitoring path is at least 10 meters from the drip line of the trees.
