# 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 m onitoring 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 pl ans, conduct network assessments every years, perform quality assurance activities, and in certain instances, establish NCore sites by January five

1, 2011.

This plan was prepared and submitted as part of the fulfillment to these new regulations. It represents the Washoe County H ealth District - Air Quality Ma nagement Division’s (AQMD) ambient air monitoring program activities completed in 2009 and proposed network modifications for 2010-2011.

Public Inspection Process

This monitoring network plan was available fo r public inspection from June 1 to June 30, 2010 at the AQMD website ( www.washoecounty.us/health ). A hardcopy of the plan was also available at the AQMD office. Public commen ts received during the public inspection period were submitted along with this plan to EPA Region IX.

# Overview of Network Operation

Network Design

The AQMD operated eight (8) ambient air mon itoring sites in 2009 (Figure 1). The red boundary delineates Hydrographic Area 87 (HA 87) as defined by the State of Nevada Division of Water Resources and is currently designated as “serious” non-attainment for the 24-hour PM 10 

### NAAQS and “attainment/mainten ance” for the 8-hour CO NAAQS. 2

, 3 

### Washoe County is classified as “attainment” or “unclassifiable/att ainment” for all other pollutants and averaging times.

Figure 1 Washoe County AQMD Ambient Air Monitoring Sites

2 40 CFR 81.329.



### Washoe County Air Quality Management Division 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. As of June 1, 2010, EPA has not taken final action on the request.

### Washoe County Air Quality Management Division 2009 Ambient Air Monitoring Network Plan 4 Minimum Monitoring Requirements

The AQMD’s ambient air monitoring network m eets the minimum monito ring requirements for all criteria pollutants pursuant to 40 CFR 58, Ap pendix D. Tables 2 through 6 provide pollutant specific monitoring requirements. The design va lues are based on ambient air monitoring data for single (2009 for NO 2 

### and CO) or multiple (2007-2009 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, 2000-2009”. The 2009 population data are from the Nevada State Demographer’s Office. 4

### Washoe County Air Quality Management Division 2009 Ambient Air Monitoring Network Plan 9 Review of Changes to PM 2.5 

### Monitoring Network

The geographic area of Washoe County is curre ntly designated as either Attainment or Attainment/Unclassifiable fo r the 24-hour and annual PM 2.5 

### NAAQS. Although the current PM 2.5 

### design value (39.3  g/m 3 

### ) violates the 24-hour NAAQS, ambient air monitoring data from June/July 2008 were influenced by wildfires in Northern California. An exceptional events request was submitted to EPA Region IX in October 2009. The PM 2.5 

### design value includes these data until EPA determines concurrence with the request.

In the event that a revi ew of changes to the PM 2.5 

### monitoring network is required, the annual network plan and five year network assessment w ould be used to provide for this review. No changes are proposed to the PM 2.5 

### monitoring network for 2010-2011.

Data Submission Requirements

Precision and Accuracy Reports for 2009 were submitted to AQS for the: 1 st 

### quarter in May 2009, 2 nd 

### quarter in September 2009, 3 rd 

### quarter in December 2009, and 4 th 

### quarter in February 2010.

Annual Data Certification for 2009 was submitted to EPA on April 23, 2010.
