2015 Ambient Air Monitoring Network Plan 1 

# 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 assurance 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 regulations. It represents the Washoe County Health District - Air Quality Management Division’s (AQMD) ambient air monito ring program activities completed in 2014 and proposed network modifications for 2015-2016.

Public Inspection Process

This monitoring network plan was available for public inspection from June 1 to June 30, 2015 at the AQMD website ( OurCleanAir.com ). A hardcopy of the plan was also available at the AQMD office

.

# Overview of Washoe County Health District Network Operation

Network Design

The AQMD operated eight (8) ambient air monitoring sites i n 2014 (Figure 1). The blue 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. 2

, 3


## Washoe County is classified as “attainment” or “unclassi fiable/attainment” for all other pollutants and averaging times. Table 1 lists the parameters monitored in 2014 sorted by network type and site.

### 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 th e NAAQS based on recent monitoring data (2007

- 2009). The rule does not change the “Serious” non

- attainment designation.

## Monitors required for NCore: 1

Title 40 CFR 58, Appendix D, Section 4.4.2 requires an SO 2 

## monitoring network based on a calculated population weighted emissions index (PWEI). This index is calculated by multiplying the population of

a CBSA with the National Emission Inventory (NEI) data for counties within that CBSA. The calculated value is then divided by one million in order to obtain the PWEI value. PWEI monitoring requirements are as follows: 1) one monitor in CBSAs with a PWEI value greater than 5,000, 2) two monitors in CBSAs with a PWEI value greater than 100,000, and 3) three monitors in CBSAs with a PWEI value greater than 1,000,000. As shown in Table 8, AQMD used 2014 population data from the Nevada State Demographer’s Office and 2011 National Emissions Inventory data to determine that no

additional SO 2

Title 40 CFR 58, Appendix D, Section 4.5(a) requires one source- oriented SLAMS site located to

measure the maximum Pb concentration in ambient air resulting from each non-airport Pb source which emits 0.50 or more tons per year and from each airport which emits 1.0 or mo re tons per year based on the most recent National Emission Inventory. All non- airport sources of P b within the CBSA emit less than 0.5 tons per year and all airport sources within the CBSA emit less than 1.0 tons per year, according

to the 2011 NEI. Table 10 includes the two largest sources of Pb emissions in the Reno, NV CBSA. Number of Monitors

Subject: Proposed Modification to the Carbon Monoxide Monitoring Network

Dear Ms. Kurpius: Prevent. Promote. Protect.



### Pursuant to 40 CPR 58.14(c), the Washoe County Health District, 

## Air Quality Management Division
(AQMD) requests review and approval for a modification to the existing carbon monoxide (CO) monitoring network. The AQMD is proposing to:

• Discontinue CO monitoring at the South Reno SLAMS station (AQS ID 32-031-0020).

Discontinuation of CO monitoring at the South Reno SLAMS station is based on this monitor never exceeding or violating 1-hour nor the 8-hour CO National Ambient 

## Air Quality Standard (Table 1 ).

2004-2013 Since 1990

1 -hour 3.1 8.4

8 -hour 2.1 5.3

Table 1. Highest CO concentrations (ppm) at South Reno (32-031-0020)

over the past ten years and since reporting began in 1990.

The South Reno CO monitor will be removed and data from the Reno 3 

### (-4 miles geodesic distance)

and Toll (-5 miles geodesic distance) sites will be used for comparative CO data as needed. The
AQMD is proposing to complete this system modification by October 1, 2014. After incorporating

this system modification, the CO monitoring network will continue to meet the minimum monitoring requirements specified in 40 CPR 58, Appendix D.

Washoe County Health District
P.O. Box 11130 Reno, Nevada 89520-0027

Dear Mr. Inouye:

This letter is in response to your June 2014 request for approval for the discontinuation of State Local

Air Monitoring Station (SLAMS) carbon monoxide (CO) monitoring at the South Reno site (AQS ID: 32-031-0020). Washoe County Health District Air Quality Management Division proposed the

discontinuation of CO monitoring at the South Reno site in its Ambient Air Monitoring Network Plan they submitted to the U.S. Environmental Protection Agency (EPA) in July 2014 (Page 8). The plan was available for public inspection prior to its submittal to EPA and received no public comments on this proposed monitoring network change.

Per 40 CFR §58.14, monitoring agencies are required to obtain EPA approval for the discontinuation of
SLAMS monitors. According to certified data submitted to EPA’s Air Quality System (AQS) since beginning operation in 1990, the CO monitor at South Reno has never recorded a violation of any CO

National Ambient Air Quality Standards (NAAQS). Based on data from 2009-20 13. Our statistical analysis (see enclosed) demonstrates that there is a less than 10 percent probability of exceeding 80 percent of any CO NAAQS at this site during the next three years (2014-2016). Concentrations captured
for a portion of 2014 continue to show low values. These monitors are not specifically required by an attainment or maintenance plan and you continue to operate five other CO sites throughout Washoe County, which is more than the minimum required SLAMS CO sites as described in 40 CFR §58, Appendix D. Therefore, the site closure meets the criteria set forth in 40 CFR §58.14(c)(1) for SLAMS

monitor discontinuation.

Based on this analysis, EPA approves your request to discontinue CO monitoring at South Reno. Please

include this modification and EPA’s approval in your next annual network plan. If you have any questions, please contact me at (415) 947-4534 or Katherine Hoag (Hoag.Katherine@epa.gov) at (415)

972-3970.

Sincerely,

Meredith Kurpius Manager, Air Quality Analysis Office

Subject: Proposed Modification to the Washoe County Health District, Air Quality Management Division Ambient Air Monitoring Network

Dear Ms. Kurpius:

Pursuant to 40 CFR 58.14, the Washoe County Health District, Air Quality Management Division (AQMD) requests revi ew and approval for a modification to the existing ambient air monitoring network. The AQMD is proposing to:

1. C losure of the Galletti SLAMS (AQS ID 32 -031-0022) including discontinuation of all monitors (CO, PM 10 

## , PM 2.5 

## , PM 10

- 2.5 

## , and meteorology); and

2. Initiate a Special Purpose Monitor (SPM) for 18 months and establishing a State and Local Air Monitoring Stations (SLAMS) in the Spanish Springs area of southern Washoe County to monitor Ozone, PM 10 

## , PM 2.5 

## , PM 10

- 2.5 

## , and meteorology.

In November 2014, the Nevada Department of Transportation (NDOT) informed the AQMD of an emergency paving project requiring the Galletti SLAMS to be removed its current location. Final quality assurance verifications were conducted during the week of November 17, 2014. CO and PM data through the final verifications will be submitted to AQS. Data capture will not meet 75 percent

for the October

- December 2014 reporting period. As of March 1, 2015, t he emergency paving project has not been completed. NDOT ’s paving project and reconfiguration will make it extremely difficult

to return to Galletti’s original location.

The p roposed modifications are consistent with the AQMD 2010 Network Assessment and 2014

Annual Network Plan. Attached are data demonstratio ns (Appendices A, B, C) and an Excel spreadsheet (Network Modification Request (2015

- 03

- 05).xlsx) to support AQMD’s proposal to close

Galletti. Additional case

- by

- case justifications for the closure of Galletti include proximity to trees

and NDOT’s “dirt pile” operation

. PM 10 

## and PM 2.5 

## concentrations were impacted by the American/Rim (2013) and King (2014) Fires. These data are flagged in AQS with either Informational or Request to Exclude flags. An Exceptional Events Demonstration for the

American/Rim Fires was submitted to EPA Region IX in 2014. A d emonstration for the King Fire is expected to be submitted in Fall 2015.

Dear Mr. Inouye: 

# APR 2 2 2015

This letter is in response to your March 5, 2015 request for approval for the discontinuation of

SLAMS (State or Local Air Monitoring Station) CO, PM10, PM2.s, and PM10-2.s monitoring at the

Galletti site (AQS ID 32-031-0022) and for the initiation of a new SLAMS in the Spanish Springs area. Washoe County Health District Air Quality Management Division (Washoe County AQMD) proposed the relocation of the entire Galletti monitoring site in its Ambient Air Monitoring Network Plan submitted to the U.S. Environmental Protection Agency (EPA) in July

2014 (page 8). The plan was available for public inspection prior to its submittal to EPA and

received no public comments on this proposed monitoring network change. EPA did not act on
the request as part of the network plan approval, as the network plan did not contain sufficient

information.

As noted in Washoe County AQMD's request, the Galletti site was forced to close in late 2014

due to an emergency paving project undertaken by the Nevada Department of Transportation. In

addition

, there are trees within 10 meters of monitor inlets and probes at the Galletti site, which

does not conform to 40 CFR §58 Appendix E siting. This siting issue was a finding in EPA's

technical systems audit of Washoe County AQMD in September 2013. EPA also recommended

that Washoe County AQMD evaluate the appropriate spatial scale for PM measurements given

the presence of a nearby minor particulate matter source. Washoe County AQMD has been

unable to resolve these 40 CFR 5§8 Appendix E siting issues at the existing site

.

The CO, PM10, PM2.s, and PM10-2.s monitors at the Galletti site are not specifically required by an attainment or maintenance plan and Washoe County will continue to meet the minimum required

SLAMS sites as described in 40 CFR §58, Appendix D for each of these pollutants after this site

is closed. Washoe County AQMD will also continue to monitor for PM2.s at two SLAMS, for

PM10 at five ST

, AMS, 

## and for CO at four SLAMS. All three pollutants will continue to be

monitored at Reno3 (32-031-0016) and Sparks (32-031-1005) which are approximately 1

. 5 miles

west and 2.1 miles east, respectively, of the Galletti site.

Per 40 CFR §58.14, monitoring agencies are required to obtain EPA approval for the

discontinuation of SLAMS monitors

. Washoe County AQMD's statistical analysis, based on 2009-2013, demonstrates that there is a less than 10 percent probability of exceeding 80 percent

of any CO NAAQS (National Ambient Air Quality Standards) at this site during the next three

Printed on Recycled Paper

## years (2014-2016). 2014 concentrations continue to show low values, with a maximum one-hour

concentration of 2.8 parts per million

. EPA approves the closure for CO at Galletti in accordance

with 40 CFR §58.14(c)(l).

Washoe County AQMD's statistical analysis for PM10 demonstrates, using the annual maximum

24-hour concentrations from 2009-2013, that there is just over a 10 percent probability of exceeding 80 percent of the PM10 NAAQS at this site during the next three years (2014-2016).

The 90 percent confidence interval (CI) associated with a 10 percent probability of exceeding 80

percent of any PM10 NAAQS is 120

. 0 μg/m 3

, 

## and the 2009-2013 time period has a CI of 120.6 μg/m 3

. 

## If the days in 2013 that are flagged as exceptional events due to the American and Rim

Fires are removed from the dataset, the 2009-2013 data demonstrate that there is a less than 10

percent probability of exceeding 80 percent of the PM10 NAAQS. Also, the statistical analysis of

2008-2012 data meets the criteria for having less than a 10 percent probability of exceeding 80

percent of the PM10 NAAQS, with a CI of 103.7 μg/m 3

.



## Since the PM2

. s monitor at Galletti ran from January 2013 through mid

- November 2014, there is

not enough historical information to evaluate the closure under 40 CFR §58.14(c)(l). Since

insufficient data are available to calculate a single design value, the annual mean and 93th percentiles were compared between Galletti and the PM2.s monitor at Sparks (32-031-1005). As previously noted, Sparks is 2.1 miles east of the Galletti site

. Based on 2013 and preliminary

2014 data, the armual means are higher at Sparks than at Galletti, and the preliminary 2014 93th percentiles are higher at Sparks than at Galletti. The 2013 93th percentiles at Sparks and Galleti

are similar (38.2 μg/m 3 

## and 41.1 μg/m 3 

## respectively) and are higher at Sparks than at Galletti

when flagged exceptional events due to the American and Rim fires are excluded.

While EPA has not concurred on the Galletti PM10 and PM2.s flagged exceptional events on 2013
data, the American/Rim fires burned a total of 284,754 acres of forest from August through

October 2013 in the Sierra Nevada Mountains, upwind of the Reno area. These fires resulted in

elevated PM2

. s and PM10 concentrations above what is usually observed in August and September without the contribution of fire emissions, and the effects they had on air quality in

California and Nevada were widely discussed in the news. Finally, these wildfires affected air quality similarly at the Sparks, Galletti and Reno3 sites

. Given these factors, that Washoe County

APCD has already been forced to close the site, and that the existing site has significant siting

issues that Washoe County APCD has been unable to resolve, EPA approves the closure for

PM10 at Galletti in accordance with 40 CFR §58.14(c)(l), and approves the closure of the PM2.s

monitor at Galletti on a case

- by-case basis per 40 CFR §58.14(c). EPA also approves the

discontinuation of meteorology measurements and of reporting PM10-2.s data from this location,

neither of which were required.

EPA has also reviewed the new site proposal for Spanish Springs. According to the information presented, the new site will operate as a SPM for 18 months and then is expected to be converted

to a SLAMS. The proposed location meets siting requirements and improves Washoe County
AQMD's overall network coverage. The addition of a site in Spanish Springs was also a
recommendation in Washoe County AQMD's 2010 Network Assessment. Per 40 CFR
§58.14(b), EPA approves the new Spanish Springs site for Ozone, PM10, PM2.s, and PM10-2.s, as a
SPM for 18 months and then expected conversion to a SLAMS.

## Please include these network modifications and EPA's approval in your next annual network plan. If 

## you have any questions, please contact me at (415) 947-4534 or Katherine Hoag (Hoag.Katherine@epa.gov) at (415) 972-3970.
