EXECUTIVE SUMMARY 

The Nogales PM2. 5Nonattainment Area (Nogales NA) is located 66 niiles south of Tucson, covering 

approximately 76 square niiles along the International border with Mexico in Santa Cruz County. The 

City of Nogales and portions of Rio Rico, an unincorporated community, occupy most of the 

nonattainment area. 

The Nogales NA was designated nonattainment for the 2006 PM 2. 5National Ambient Air Quality 

Standards (NAAQS) based on monitoring data from 2006-2008. PM 25 conditions in the region have 

improved since that time. On January 7, 2013, subsequent to the designation, EPA finalized a clean 

data determination for the Nogales planning area under the Clean Data Policy (see 78 FR 887, January 

7, 2013). This action suspended requirements to submit State Implementation Plan (SIP) elements related 

to attainment of the NAAQS including reasonable further progress milestones, attainment demonstrations, 

control measures, and contingency measures. This state implementation plan revision addresses the 

remaining Clean Air Act (CAA) requirements applicable to the Nogales NA. Accordingly, this document 

is organized as described below. 

Chapter 1 provides an overview of the Nogales NA and Santa Cruz County. This chapter includes 

discussions about the climate, physiography, population, and economy of the area and the impact each 

has on ambient PM2, 5concentrations. The chapter also includes an account of the regulatory history of the 

PM2. 5NAAQS and the Nogales NA. 

Chapter 2 outlines CAA requirements for PM 2. 5nonattainment areas. 

Chapter 3 describes the Nogales ambient monitoring network, provides a description of the monitoring 

equipment, and presents PM 2, 5monitoring data collected by monitors in the area from 1999- 

2012.Monitoring data shows the area continued to meet the NAAQS in 2012. 

Chapter 4 describes the emission inventory for the base year of 2008 and projections to 2010 for both 

minor and significant area and non-area sources (depicted in Figure ES-1).

1.0 INTRODUCTION 

Chapter 1 provides a description of the Nogales Nonattainment Area (Nogales NAA). This chapter also 

provides the regulatory history of the Nogales NAA and the 24-hour PM 2.5National Ambient Air Quality 

Standards (NAAQS). 

1.1 PM2.5 Air Quality Standards 

1.1.1 1997 Fine Particulate Matter NAAQS 

EPA revised the NAAQS for particulate matter in July 1997; see 62 FR 38652; (July 18, 1997). EPA 

established a health-based PM 2.5standard and retained the PM, ostandard as a"coarse" standard 

protecting both health and welfare. The 24-hour PM 2.5standard was set at 65 μg/m3and the annual 

standard was established at 15 μg1m3 . Rather than using a graduated scale of PM Iononattainment area 

designations, EPA designated PM2.5nonattainment areas as only either "nonattainment" or 

"attainment/unclassifiable." A series of legal challenges delayed implementation of the 1997 PM2,5 

standards until December 17, 2004, when EPA finalized attainment/nonattainment designations for the 

1997 PM2,5standards (70 FR 19844; April 14, 2005). 1Nogales, Arizona was not designated 

nonattainment for the 1997 PM2.5 standard. 

1.1.2 2006 Fine Particulate Matter NAAQS 

While the 1997 PM2, 5standards were delayed by court proceedings, EPA conducted a review of the latest 

medical studies to determine the standard's adequacy. As result of this subsequent review, EPA 

promulgated revised NAAQS for PM2,5on October 17, 2006; see 71 FR 61144 EPA lowered the 24-hour 

standard from 65 μg/m3to 35 μg/m3and retained the 1997 annual standard of 15 μg/m 3. A comparison of 

the 1997 and 2006 PM2,5standards is shown in Table 1.1. The Nogales area was designated 

nonattainment for the 2006 24-hour PM 2.5 standard on November 13, 2009 (74 FR 58688), effective 

December 14, 2009.

1.2 Nogales Nonattainment Area Description 

The Nogales NAA in southern Arizona is within Santa Cruz County on the international border with 

Mexico, and includes the City of Nogales, the community of Rio Rico, and unincorporated portions of the 

County. The area is depicted in Figure 1.1. The nonattainment area is codified at 40 CFR 81.303 and is 

bounded as follows: The portions of the following Townships which are within the State of Arizona and 

lie east of 111 longitude: T23S, R13E; T23S, R14E; T24S, R13E; T24S, R14E.

1.3 Climate and Physiography 

The Nogales NAA is located in Santa Cruz County, the smallest county in Arizona in terms of size. The 

Nogales NAA is located in the southernmost portion of the County alongside the U.S./Mexico border. This 

region of the Sonoran Desert is characterized by north-south elongated valleys surrounded by mountain ranges. 

Nogales, Arizona is located in a valley created by the Nogales Wash, a tributary of the nearby Santa Cruz 

River. 

The mean elevation in Nogales, Arizona is 3,865 feet above sea level. Mountain ranges near Nogales 

include the Patagonia Mountains to the east and the Tumacacori, Atascosa, and Pajarito Mountains to the 

west. Approximately twenty-five miles to the north are the Santa Rita Mountains and Madera Canyon in 

El 
the Coronado National Forest where Mount Wrightson rises to an elevation of 9,432 feet. Northwest of 

Interstate 19 are the Cerro Colorado, Las Guijas, and Sierrita Mountain Ranges. 

The mean elevation in Nogales, Sonora, Mexico is 4,265 feet above sea level. ZThe highest elevation is 

5,380 feet. The elevation drops approximately 709 feet from the southernmost edge of the Nogales, 

Sonora, Mexico urban boundary to the Nogales NAA northern boundary line. 

The average daily maximum temperature is 79.7 °F, based on a 62-year average of ineteorological data 

(see Table 1.2). The highest monthly daily maximum average temperature (94.1 °F.) occurs in July, and 

the lowest monthly daily minimum average temperature (64.3 °F.) occurs in January. 

The yearly average total rainfall for the Nogales area is 17.21 inches, as shown in Table 1.2. The majority 

of this precipitation falls during in July and August, when warm moist air penetrates Arizona from the 

Gulf of Mexico. The area receives approximately 8.5 inches of precipitation during this time. The area 

receives an average of only 0.22 inches of rain in May, the driest month of the year.

1.4 Population 

Table 1.3 includes historical and projected population estimates for the Nogales area. Estimates for 1990 

and 2000 were obtained from the U.S. Census Bureau; all other estimates and projections were obtained 

from the Arizona Department of Adniinistration (ADOA). According to 2010 population estimates, 66 

percent of the County's population resides within the boundaries of the Nogales NA, including portions 

of Rio Ric04and the all of the City of Nogales.

1.5 Santa Cruz County and City of Nogales Economy 

The City of Nogales was founded in 1880 when a trading post opened on the Intemational border; two 

years later, a railway running through Nogales connected the United States and Mexico. Today the 

econonzies of Nogales, Arizona and Ambos Nogales, Sonora are largely interdependent. According to the 

ACA, 47 percent of Santa Cruz County's annual sales tax revenue is generated from purchases made by 

residents of Mexico.s 

There are two international ports of entry (POE) in the Nogales area, the DeConcini POE in downtown 

Nogales and the Mariposa POE 1/2 mile to the west on Arizona State Route 189. The DeConcini POE 

does not accept commercial trucks, all of which are required to cross the border at the Mariposa POE. 

From November through April, approximately 136,000 trucks haul produce from Mexico to warehouses 

in Nogales; approximately 200,000 U.S. trucks distribute the fresh produce to supermarkets in the United 

States and Canada. The Mariposa POE serves as the gateway to 50 percent of all fresh fruits and 

vegetables shipped into the U.S. from Mexico. 6An expansion of the Mariposa POE is expected to be 

completed by 2014. 

The recent economic downturn (which began in 2007) affected the region's construction industry, by 

slowing construction activity significantly. While exact figures are not available for the Nogales NA, 

Table 1.4 provides building perniit information for the area that is illustrative of relative conditions for the 

planning area. Only five building permits were issued in 2010 in the City of Nogales, compared to 60 in 

2000 (see Table 1.4.)

Table 1.5 contains labor force statistics for Santa Cruz County published by the Census Bureau.' The 

retail and wholesale trade industries employed 29.7 percent of the County's working population; an 

additional 6.8 percent were employed in transportation and warehousing, testimony to the importance of 

International trade on the local economy. The largest employers in the area include Wal-Mart, the 

Department of Homeland Security, Santa Cruz County, the City of Nogales, and Cochise Community 

College. Unemployment in Santa Cruz County is much greater than the State average. The County's 

unemployment rate was 17.7 percent in September 2012, 8 whereas the State's unemployment rate was 8.3 

percent. 9

2.0 GENERAL SIP APPROACH - REGULATORY REQUIREMENTS AND GUIDANCE 

2.1 Regulatory Background 

In December 2007, based on ambient PM2.5 monitoring data from 2004-2006, ADEQ recommended that 

the Nogales area be designated as nonattainment for the 2006 PM 2, 524-hour standard. Arizona 

recommended the same boundaries as the existing PM iononattainment area (see Figure 1.1). 10EPA 

concurred with ADEQ's boundary recommendation. l ~ 

Based on this data from 2004-2006, the Nogales NA was designated non-attainment for the 24-hour PM2,5 

2006 NAAQS and unclassifiable-attainment for the annual standard on November 13, 2009 (74 FR 

58688) and the attainment date established for the Nogales NA was December 14, 2014, with an 

attainment SIP due on December 14, 2012. 

Subsequently, air quality monitoring data from 2009-2011 showed that the area had attained the 24-hour 

PM2.5NAAQS. On October 30, 2012, EPA proposed to determine that the Nogales NA had met the 24- 

hour PM2.5NAAQS based on monitoring data from 2009-2011; see 77 FR 65656. EPA finalized this 

clean data determination on January 7, 2013; see 78 FR 887. In conjunction with this clean data 

determination, EPA suspended CAA SIP requirements related to attaining the NAAQS for as long as the 

area continues to attain the standard. These SIP planning elements include reasonable further progress 

(RFP) requirements, attainment demonstrations, reasonably available control measures (RACM), 

contingency measures, and other requirements related to attainment. 

2.2 Clean Air Act (CAA) Requirements 

Table 2.1 lists the CAA requirements for PM 2 ,5nonattainment areas and specifies the remaining 

requirements ADEQ addresses in this document. The listed elements include the general requirements for 

nonattainment areas under CAA Title I, Part D, Subpart 1 as well as the particulate matter specific 

provisions of Subpart 4. Although Subpart 4 contains specific planning and scheduling requirements for 

PMIOnonattainment areas, under a recent court decision, these same statutory requirements also apply for 

PM2,5nonattainment areas. 12The suspended CAA elements related to attainment of the 2006 PM2.5 

NAAQS and the Clean Data Determination are noted in the table below. 

10ADEQ, "Technical Support Document for Recommendation that the Nogales, Arizona Area Be Designated as a 

PM2.5Nonattainment Area". Submitted to EPA on December 3, 2007.

12Natural Resources Defense Council v. EPA, 706 F.3d 428 (D.C. Cir. 2013) (Petitioners challenged EPA's 

decision to promulgate the 1997 PM2.5NAAQS pursuant to the general implementation provisions of Subpart 1 of 

Part D of Title I of the Clean Air Act. The Court remanded to EPA to re-promulgate the rules pursuant to Subpart 4). 

With this decision, ADEQ presumes that all PM2 ,5Standards from 1997 forward will now be subject to Subpart 4. 

Under section 188 of the CAA, all areas under Subpart 4 would initially be classified by operation of law as 

"moderate" nonattainment areas. If EPA were to classify the Nogales area under Subpart 4, ADEQ assumes the area 

would be classified as "moderate," therefore, for purposes of this plan, ADEQ considers only the Subpart 4 

provisions related to "moderate" nonattainment areas and not those for "serious" areas.

3.0 AIR QUALITY MONITORING 

This chapter describes the Nogales Nonattainment Area (NA) monitoring network and provides an 

analysis of monitoring data and trends. 

3.1 Monitoring Site, Equipment, and Quality Assurance Procedures 

The primary goal of PM2,5monitoring in the Nogales NA is to collect the data necessary to compare 

ambient air quality values with the PM2.5NAAQS and fulfill the regulatory requirements for PM2,5 

monitoring in the nonattainment area. The Nogales NA instruments were installed and are maintained in 

accordance with federal siting and design criteria 13and consistent with ADEQ's State of Arizona Air 

Monitoring Network Plan for the Year 2012. The ADEQ network plan, including the Nogales monitoring 

was approved in 2010. 14In 2011, however, EPA identified the Nogales Post Office as a site where 

ADEQ was not sampling at the required frequency. ADEQ addressed this sampling frequency deficiency 

13 40 CFR Part 58, Appendices D and E. 

la Lakin, Matthew, EPA. Letter to Eric Massey, December 10, 2010 (Appendix B). 

11 
in ADEQ's State of Arizona Air Monitoring Network Plan for the Year 2012 and committed to installing a 

continuously operating FEM BAM to serve as the primary PM 2. 5monitor to be compared to the NAAQS. 

Historically, ADEQ operated collocated filter-based PM 2,5federal reference method monitors (Partisols) 

and one continuous Beta Attenuation Monitor (non-FRM/FEM BAM) at the Nogales Post Office site in the 

center of the Nogales business district. The monitoring site was selected in an effort to measure the 

maximum particulate matter impacts on the Nogales population. The filter-based monitors have been 

operated on a one-in-six day sampling schedule since 1999 1999 and remain on the same sampling schedule 

at the time that this document was developed. 

The continuously operating Beta Attenuation Monitor (BAM) has been monitoring PM 2,5at the Post Office 

site since February 2004; data collected by this monitor were not used to determine compliance, but is used 

to supplement the data collected by the filter-based monitor for air quality studies. ADEQ updated the nonFederal Reference Method BAM monitor to a continuous Federal Equivalent Method (FEM) BAM on April 

1, 2013. Prior to installation of the FEM BAM the Partisol monitor was used for comparison to the PM2.5 

NAAQS. With the update of the BAM instrument to the FEM BAM, ADEQ addressed the sampling 

frequency concern identified in the 2011 and 2012 EPA network plan approval letters for the Nogales PMzs 

monitoring site. 

The PM2. 5instruments are neighborhood-scale monitors suited to measure concentrations within a 1/3 of a 

mile radius (40 CFR 58, Appendix D). Table 3.1 features the location, methods, and parameters measured 

at the site as of June 2013. Figure 1.1 depicts the location of the Nogales PM 2,5monitor site. 

Monitoring data are submitted to EPA's Air Quality System (AQS) database. All data described in this 

chapter are included in AQS and have been quality assured, meeting the requirements specified in Title 

40 of the Code of Federal Regulations (CFR) Part 58 Appendix A and, unless otherwise noted, meet the 

completenesa criteria for monitoring data specified in 40 CFR, Part 50, National Primary and Secondary 

Ambient Air Quality Standards: Appendix N. A minimum completeness of 75 percent per quarter for 

each year period is required at each monitoring site.

3.2 Air Quality Data 

Figure 3.1 presents the four highest 24-hour values recorded by the filter-based PM 2,5monitor from 1999- 

2012. Compliance with the PM2.5NAAQS is determined based on the 98` hpercentile of ineasured ambient 

concentrations in a three-year period. With a one-in-six sampling schedule, the 98` y' percentile is typically 

equivalent to the 2°d24-hour high value (78 FR 3086, January 15, 2013). As can be seen in Figure 3.1, 

which is presented for informational purposes only, the second high value has repeatedly been below the 

PM2.5NAAQS of 35 μg/m3since 2007. In order to determine official compliance with the 24-hour 

PM2.5 NAAQS, the 24-hour design values, expressed as the three-year average of the annual 98 6' 

percentile values, are provided in tabular form in Table 3.2. Table 3.2 verifies compliance with the 24- 

hour PM2.5 NAAQS since the 2007 — 2009 period.

4.0 EMISSIONS INVENTORY 

As indicated in Table 2.1, an emissions inventory is required for the Nogales NA under CAA Section 

172(c)(3). The EPA Clean Data Determination relied on monitoring data for the 2009-2011 time periods. 

To be consistent with the determination, ADEQ developed an inventory using 2010 emissions 

information for the Nogales NA. 

4.1 Nogales, Arizona Eniission Sources 

The total emissions for Nogales, Arizona for PM 2.5and PM2,5precursors are summarized in Table 4.1. A 

projected NA population growth of 1.1% between the years of 2008 and 2010 has resulted in stagnant or 

slightly increasing estimated emissions for all pollutants in a11 sectors except On-road Mobile Emissions, 

where estimated eniissions declined. Total sector estimated emissions between the years of 2008 and 

2010 within the Nogales NA declined due to the decreases in On-road Mobile Emissions. The On-road 

Mobile Emission decreases are primarily attributable to advances in motor vehicle control technologies 

and fuel efficiency. A detailed emission inventory discussing emission calculations, methodologies and 

total results can be found in the Technical Support Document in Appendix A. 

Population increases will result in increased emissions in the following sectors: construction; mobile 

brake wear, tire wear, and dust re-entrainment; waste disposal; and fuel burning. A detailed emission 

inventory discussing emission calculations, methodologies and total results can be found in the Technical 

Support Document in Appendix A.

5.0 NEW SOURCE REVIEW 

Stationary source permitting program requirements from sections 172(c)(5) and 189(a)(1)(A) 

have met by the State's adoption, implementation, and submittal of NSR program regulations. In 

general, state permitting programs for major and nunor sources are contained in: Arizona Administrative 

Code Title 18, Chapter 2, Articles 3 and 4. Any permitted sources are subject to the monitoring, 

reporting, and certification procedures contained in AAC R18-2-306 and AAC R18-2-309 respectively 

(or similar County rules). ADEQ has authority pursuant to ARS § 49-101 et seq. to monitor and ensure 

source compliance with all applicable rules and permit conditions for sources in its jurisdiction. 

Any new major source proposing to operate in the Nogales area or major modification to an existing 

source is subject to the provisions of AAC R18-2-403, "Permits for Sources Located in Nonattainment 

Areas." These programs address New Source Review requirements applicable to PM sources. If a new 

source is not a major source it is required to obtain a permit under minor source permitting rules at AAC 

R18-2-Article 3. 

A SIP revision was adopted and submitted to EPA on October 29, 2012, to bring the Arizona SIP for 

areas under the jurisdiction of ADEQ into compliance with the NSR and PSD requirements of CAA 

Section 110(a)(2)(C) and 40 C.F.R. Part 51, Subpart I, with the exception of the requirements pertaining 

to GHGs. This submission has not yet been acted on by EPA. 

15 
6.0 CONFORMITY 

As indicated in Table 2.1, certain conformity requirements are required for the Nogales NA under 

176(c)(4), general conformity. 

6.1 General Conformity 

General conformity for the Nogales, Santa Cruz County area must still be addressed to assure PM2.5 

emissions from any federal actions or plans do not exceed the rates outlined in 40 CFR § 93.153(b) (see 

75 FR 17254, April 5, 2010). Criteria for making determinations and provisions for general conformity 

are located in R18-2-1438 of the Arizona Administrative Code. ADEQ commits to review and comment, 

as appropriate, on any federal agency draft general conformity determination it receives pursuant to 40 

CFR § 93.155 for activities planned for this air quality planning area. 

7.0 CONCLUSION 

In January 2013 EPA determined that the Nogales nonattainment area had attained the 2006 24-hour PM 

2.5 NAAQS. As a result of the determination, the requirements to submit an attainment demonstration, 

RACM, an RFP plan, contingency measures, and any other CAA elements related to attainment of the 

2006 PM2 , 5NAAQS are suspended as long as the area continues to attain the standard. 

This information contained in this document demonstrates that all other remaining CAA requirements for 

nonattainment areas are met. ADEQ requests that EPA approve these demonstrations as a revision to the 

state implementation pian.

I Introduction 

1.1 Purpose 

This document provides a PM2,5emission inventory for all sources within the Nogales 

Nonattainment Area (NA) and a detailed description of the derivation of those emissions 

estimates. The Arizona Department of Environmental Quality (ADEQ) has created this PM2.5 

emissions inventory to support a PM 2.5State Implementation Plan (SIP) for the Nogales NA, 

located in Santa Cruz County, Arizona. Since the Nogales NA met the PM-1. 5Nationai Ambient 

Air Quality Standard (NAAQS) based on ambient monitoring data from 2009 — 2011, ADEQ 

selected 2010 to serve as a representative emission inventory for the 2009 — 2011 period. 

1.2 Sources of PM2.5 

PM2 .5refers to fine particulate matter of 2.5 microns or less in aerodynamic diameter. Fine 

particles originate mostly from combustion sources and secondary aerosol generation processes, 

while coarse particles (PM IO— PM1, 5 ) usually originate from mechanical activities and fugitive 

source categories. Typical sources of PM2,5include fugitive dust, open burning (including wild 

fires), and, to a greater extent, fuel combustion sources and mobile source exhaust. 

There are two types of PM2.5 , namely primary and secondary particulates. Both the primary and 

secondary particles are listed in this emission inventory. Primary particles are directly emitted by 

various sources. Secondary particles are derived from the oxidation of primary gases such as 

nitrogen and suifur oxides into nitric acid and sulfuric acid. The precursors for these aerosols (i.e. 

the gases from which they originate) are included in the current inventory. In the presence of 

ammonia, secondary aerosols often take the form of ammonium salts; i.e. ammonium sulfate and 

ammonium nitrate (both salts can be dry or in aqueous solution). In the absence of ammonia, 

secondary compounds take the acidic forms of suifuric acid (liquid aerosol droplets) and nitric 

acid (atmospheric gas). In addition, organic matter (OM) can be primary or secondary 

particulate. As a secondary particulate, OM is derived from the oxidation of volatile organic 

compounds (VOCs). 

To meet the PM2.5 NAAQS, ADEQ regulates primary particulate emissions and precursors to 

secondary particulate emissions (NO x, SO, VOCs, and N113 ). 

1.3 Emissions Inventory Overview 

Data for this emissions inventory primarily came from versions 1.5 and 2.0 of the Environmental 

Protection Agency's (EPA) 2008 National Emissions Inventory (NEI) for Santa Cruz County, 

Arizona; with the exception of the Nonpoint sector. Nonpoint sector emissions reported in this 

emission inventory were the same as those reported to EPA for the development of the 2008 NEI 

and derive from the Arizona Emission Inventory System (AEIS). Any use of data not originating 

from the 2008 NEI or AEIS is noted later in this document. The 2011 NEI was not used as a 

basis for this Nogales NA EI as the 2011 NEI had not yet been released, or was released 

subsequent to the development of this document. The NEI is a comprehensive and detailed 

estimate of air eniissions of both criteria and hazardous air pollutants from ali air emission 

sources and is based partialiy on emission estimates and emission model inputs provided by state, 

local, and tribal air agencies for sources in their respective jurisdictions, and supplemented by 

data developed by the EPA. More information about the 2008 NEI, including methodologies and 
assumptions used in producing this emissions inventory, may be found at the following URL: 

htip://www.epa.gov/ttn/chief/net/2008inventoiy.html. 

The NEI estimates emissions at the county-level. To develop an inventory for the nonattainment 

area from the NEI, the county-level emissions estimates must be allocated to the nonattainment 

area. The methods used for allocating county-level emission estimates to the nonattainment area 

are described in Section 3 of this document. 

2 The Nogales Nonattainment Area 

2.1 Overview of the Area 

The southern boundary of the Nogales NA and Santa Cruz County is the U.S./Mexico border. 

The city of Nogales, Arizona is sixty miles south of Tucson, Arizona in the south-central portion 

of Santa Cruz County. Nogales, Arizona is the largest city in the nonattainment area. See Figure 

1 below. 

The Nogales NA is located within the Sonoran Desert. This desert covers 120,000 square miles 

with a minimum elevation of 2,500 feet and is in the Basin and Range topographic province. 

This topography is characterized by north-south elongated valleys surrounded by mountain 

ranges. Nogales is located in such a north-south valley created by the Nogales Wash running 

north to the Santa Cruz River. The mean elevation in Nogales, Arizona is 3,865 feet. Mountain 

ranges near Nogales include the Patagonia Mountains to the east and the Tumacacori, Atascosa, 

and Pajarito mountains to the west. Approximately 25 miles to the north are the Santa Rita 

Mountains and Madera Canyon in the Coronado National Forest, where Mount Wrightson rises to 

an elevation of 9,432 feet. Northwest of Interstate 19 are the Cerro Colorado, Las Guijas, and 

Sierrita Mountain Ranges. 

Major highways in the Nogales, Arizona area are Arizona State Route 82, which connects 

Nogales, Arizona with Patagonia, Arizona (19 miles) and Sonoita (31 miles) to the northeast, and 

U.S. Interstate 19 which connects Tucson, Arizona to Nogales, Arizona and continues south into 

Mexico, where it becomes Federal Highway 15. 

Nogales, Sonora, Mexico lies directly south of Nogales, Arizona across the international border, 

and the two areas are collectively referred to as Ambos Nogales. The communities comprise the 

largest international border community in Arizona, with a combined population of 233,411 

inhabitants in 2010. 1The mean elevation in Nogales, Sonora is 4,265 feet (Instituto Nacional de 

Estadistica Geografia e Informatica, 2005). ZAt 5,380 feet, the highest elevation in Nogales, 

Sonora is the Cerro de los Nogales (Nogales Hill). 

' Nogales, Arizona had 20,878 inhabitants and Nogales, Sonora, Melcico had 212,533 inhabitants.

2.2 Population and Urbanization 

This section presents the population information for Santa Cruz County and the Nogales NA as 

determined by the Arizona Department of Administration (ADOA). There are two population 

centers in Santa Cruz County: the City of Nogales and Rio Rico. While the entirety of the City of 

Nogales lies within the Nogales NA, only a portion of Rio Rico is contained within the boundary. 

ADOA utilizes decennial U.S. Census population data to determine State, County, and block 

level population data. These data are projected intra-decennially based on economic criteria 3and 

projected to future years using ADOA's population projection methodology taking into account 

local survival, fertility, and migration rates 4 . 

2.2.1 Santa Cruz County 

ADOA estimated the 2010 Santa Cruz County population to be 47,539; up by 1.1 percent from 47,016 

in 2008.5 

2.2.2 Nogales Non Attainment Area 

ADOA used a Geographic Information System (GIS) to estimate the population of the Nogales 

NA. The estimated 2010 population (as of July 1, 2010) was 31,413, up by 1.1 percent from their 

estimate of 31,067 for 2008. The ADOA estimated population for the city of Nogales was 21,107 

and 20,880 for the years of 2008 and 2010, respectively (Appendix A). 6This indicates that all 

population growth within the Nogales Nonattainment Area occurred outside of the Nogales, AZ 

city boundary. For Nonattainment Area population estimation, ADOA apportioned census block 

population information via a Geographic Information System (GIS) map (Appendix A). The 

populations of all census blocks that are entirely or partially within the boundary of the Nogales 

NA are identified and included in population estimates of the NA. Census 2010 population (as of 

April 1, 2010) of the blocks was summed up to obtain the Census 2010 population of Nogales 

NA, which was found to be 31,3347 (Note: The 31,334 Census population given here does not 

match the 31,413 ADOA population estimate given earlier due to a 3 month variation in the dates 

of the estimations.). At the time of the development of this document, ADOA only provided 

population estimates at the county and incorporated place level (including unincorporated balance 

of county in its entirety). Population estimates are not available for census block or specific, 

unincorporated communities (e.g. Rio Rico) in the years between decennial censuses. Therefore 

a ratio of Nogales NA population to Santa Cruz County population was calculated using 2010 

Census data in order to estimate a"constant share" ratio which could be applied to the county 

population estimates for other years in order to determine the NA population for those years. The 

2010 U.S. Census figures implied that the population of Nogales NA is 66.1°Io of the population 

of Santa Cruz County. Using the "constant share" method, this percentage was applied to the 

estimated county population for July 1, 2008 (47,016) for a 2008 Nogales NA population 

estimation of 31,067 as mentioned above.

' Based on ADOA apportionment of Nogales NA, City of Nogales population was 20,837; Rio 

Rico CDP population was 8,707; and balance of Nogales NA population was 1,790.

2.3 Land-Areas of Santa Cruz County and the Nogales NA 

Santa Cruz County comprises 1,237.6 square miles of land, or approximately 791,632 acres. g 

Using GIS and 2012 digital land maps obtained from the Arizona State Land Department, 

Arizona Land Resource Information System, ADEQ determined that the majority of land 

ownership in Santa Cruz County is distributed between the U.S. Forest Service (52.8%), private 

land-owners (35.8%), State of Arizona Trust Land (7.8%), and the U.S. Bureau of Land 

Management (1.9%). 

The Nogales NA covers a land area of 76.1 square miles. In contrast with the County, the 

majority of the land in the NA is privately owned (84.1%) with the U.S. Forest Service owning 

13.0%, and State of Arizona Trust owned land comprising 2.8% of the NA. The codified 

boundaries of the Nogales NA can be found in 40 CFR Part 81.303. The Nogales PM2.5 

nonattainment area is delineated by the following townships and ranges within the State of 

Arizona which lies east of 111 degrees longitude: T23S, R13E; T23S, R14E; T24S, R13E; and, 

T24S, R14E. 

3 Emissions Inventory Methodology 

ADEQ employed a top-down methodology for the estimation of PM 2,5and related pollutants 

emissions within the Nogales NA by utilizing information from EPA's NEI and ADEQ's AEIS. 

Point and Non-Road emissions were obtained from EPA's NEI, while non-point emissions were 

obtained from the AEIS. On-Road emissions were obtained by running the EPA approved Motor 

Vehicle Emissions Simulator (MOVES) model. 2010 was the chosen year for the Nogales NA 

emission inventory development to represent the 2009 — 2011 period for which ambient 

monitoring data showed attainment of the PM2.5NAAQS. At the time of the development of this 

document, the 2011 NEI was not yet available, therefore, emissions data from the 2008 NEI and 

AEIS served as a base for estimating 2010 emissions. For this reason, the 2010 Nogales NA 

emission inventory is primarily based on versions 1.5 and 2.0 of EPA's 2008 NEI and the AEIS. 

Since the NEI and AEIS produce county level emissions, these county level data were allocated 

to the Nogales NA by a combination of population and area scaling, as well as identifying the 

exact location of point sources. ADEQ examined each of the reported emission source categories 

for PM2,5 , NH3 , NOX, S02, and VOCs. Each source category was allocated from county-level 

emissions to NA level emissions in accordance with one of three main source type characteristics: 

whether the emission source was believed to be driven by 1) human-induced activities (resulting 

in population allocation), 2) land-use activities (resulting in area allocation), or 3) if the activity 

was specific to a certain location (resulting in either no allocation or full allocation). 

Additionally, in order to produce a 2010 emission inventory, 2008 NEI and AEIS data were 

grown by population change (2008 to 2010) where human-induced activities were identified. The 

sections below go into detail describing the methodologies used for allocating the 2008 Santa 

Cruz County emission inventory to the Nogales NA and the development of the 2010 Nogales 

NA emission inventory. Additionally, for instances where ADEQ did not use the NEI or AEIS to 

estimate emissions, a discussion of the estimation technique is included.

3.1 EPA's 2008 National Emissions Inventory 

EPA's NEI database contains information about sources that emit criteria air pollutants and their 

precursors, and hazardous air pollutants. The database includes estimates of annual air pollutant 

emissions from point, nonpoint, and mobile sources in the fifty states, the District of Columbia, 

Puerto Rico, and the Virgin Islands available at the county level. Collaborating with the states, 

EPA develops the emissions inventory and releases an updated version of the NEI database every 

three years. 

Five of the six criteria air pollutants are included in the NEI database. Emissions of carbon 

monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO Z), lead (Pb), and particulate matter 

(PMIO and PM2. 5) are specifically reported in the NEI. Ozone, the sixth criteria air pollutant, 

arises from photochemical reactions in the atmosphere rather than direct emissions from sources. 

EPA compiled the NEI database from the primary data sources listed below: 

• emissions inventories compiled by state and local environmental agencies; 

• databases related to EPA's Maximum Achievable Control Technology (MACT) programs 

to reduce emissions of hazardous air pollutants; 

• Toxic Release Inventory (TRI) data; 

• for electric generating units, EPA's Emission Tracking System / Continuous Emissions 

Monitoring data (ETS/CEM) and Department of Energy fuel use data; 

• for on-road sources, the Federal Highway Administration's estimate of vehicle miles 

traveled and emission factors from EPA's MOVES2010a computer model; 

• for non-road sources, EPA's NONROAD2008a computer model; and, 

• previous emissions inventories, if states do not submit current data. 

A complete description of the development of the 2008 NEI may be found at the following URL: 

hLtp://www.epa.gov/ttn/chief/net/2008inventoiy.html. 

3.2 On-Road Mobile Source Emissions 

In the 2008 NEI version 1, on-road mobile source emissions were calculated using EPA's 

MOBILE6.2 model. Since the 2008 NEI was developed, EPA's Motor Vehicle Emission 

Simulator (MOVES) model has replaced MOBILE6.2 as the accepted model for estimating 

emissions from cars, trucks, and motorcycles. 9On March 2, 2010, EPA approved the availability 

of the Motor Vehicle Emissions Simulator model MOVES2010 in official SIP submissions to 

EPA regarding air quality and for certain transportation conformity analyses outside the state of 

California. 10MOVES2010a replaced MOVES2010 in August 2010 and was subsequently 

revised and released as MOVES2010b in March 2012. MOVES2010b is now the state-of-the-art 

upgrade to EPA's modeling tools for estimating air emissions from cars, trucks, motorcycles, and 

buses, and is based on analyses of millions of emission test results and considerable advances in 

the Agency's understanding of vehicle emissions. In April 2012, EPA recomputed the on-road 

mobile source emissions using MOVES and populated the 2008 NEI Version 2 with the updated 

values.

3.2.1 Calculating Santa Cruz County Emissions Using MOVES 

ADEQ used MOVES2010a with an EPA supplied 2008 Santa Cruz County local MOVES 

database to obtain the most current on-road mobile source emissions for Santa Cruz County (see 

Appendix B). Use of MOVES to calculate mobile source emissions is required by EPA for SIP 

development. The above mentioned database calculated reasonable values of all analyzed 

poilutants for the year of 2008 except SO, (0 tons calculated) and VOC's (40,000 tons estimated). 

Due to these discrepancies, EPA and ADEQ agreed the most appropriate course of action for 

calculating S02 and VOC emissions would be to rerun MOVES for these pollutants using the 

national, default database Appendix D). ~ 1A population ratio of Santa Cruz County to the 

Nogales NA (Table 3.1) was used to allocate county emissions to the nonattainment area where 

applicable (Table 4.3). 

PM2 , 5emissions from on-road mobile sources fall into four categories: brake and tire wear, 

vehicle exhaust, paved road dust, and unpaved road dust. As older on-road vehicles are replaced 

with newer, cleaner vehicles, exhaust emissions are expected to decrease. Also, changes to 

cleaner fuel specifications lead to lower exhaust emissions. The overall changes in vehicle 

exhaust emissions are captured in the EPA MOVES emission model. MOVES also produces 

emissions estimates for brake and tire wear. ADEQ ran the MOVES modei for 2008 and 2010 

using the national (default) EPA database. ADEQ also ran the MOVES model for 2008 using the 

county (local) database suppiied by EPA. Since a specific (local) database was not available for 

the 2010 MOVES run, ADEQ used the outputs from the 2008 (local) database and the 2008 

national default run to create a ratio that was utilized for the 2010 MOVES run. This ratio, or 

correction factor, was then multiplied by the outputs for the 2010 national default MOVES run. 

This correction factor was applied to all pollutant emissions except S0 2and VOCs. This method 

was recommended by ADEQ and agreed upon by EPA l2. See details below for a mathematical 

example of the methodology used for on-road brake, tire-wear, and exhaust emissions using 

MOVES. Detailed breakdowns of the estimated emissions generated from this methodology are 

included in Appendix E. 

The following is an example of the steps which were foliowed to allocate/convert the MOVES 

(default) data for year 2010 to the NA data. An example calculation is at the end of Appendix E. 

A= MOVES (county) PM2.5 ORG_URA data for 2008 (local) 

B= MOVES (county) PM2.5 ORG_URA data for 2008 (default)

C= AB = adjustment ratio to go from 2008 (default) to 2008 (local) 

D= C* MOVES (county) PM2.5 ORG_URA data for 2010 (default)

3.3 Allocating the Santa Cruz County PM2,5 Emissions to the Nogales NA 

EPA has not issued formal guidance on assigning emission sources from a county level of analysis to 

a smaller subject area within that county. For the Nogales NA emissions inventory, ADEQ used a 

combination of population ratios, land area ratios, and source locations within the Nogales NA to 

determine the appropriate ailocation of county-wide emissions to the Nogales NA. A summary of the 

allocation ratios is presented in Table 3.1 below. More detailed discussions of the allocation methods 

are provided in the subsequent Sections. 

Table 3.1 

Sunmumnaryof Santa Cruz County & N ales NA Po ulation Data 

Santa Cruz County No ales NA Allocation Ratio 

Area (square miles) 1,237.6 76.1 6.15% 

2008 Po ulation 47,016 31,067 66.1% 

3.3.1 Emissions Allocation Based on Population 

One method of allocating emissions from a county-level to a NA is to scale those emissions by a 

population ratio. In some cases, it is logical to scale source categories by population, since the 

rate of activities causing the emissions is more closely related to the number of people within a 

given area than to other factors, such as a specific land area relationship. 

As described in Section 2.2.2, ADEQ used ADOA population estimates of the Nogales NA and 

Santa Cruz County to calculate a population ratio. The premise that underlies these calculations 

is: the City of Nogales and the allocated population of Rio Rico comprise nearly all of the 

population within the nonattainment area (this was determined by analysis of aerial photography 

of the region). 

When allocating emissions based on population, the county-level emissions for a given source 

category were multiplied by a factor of 66.1% or 0.661 for the year of 2008 to give the respective 

source category emissions for the Nogales NA. If the likely magnitude of source category emissions 

varied with the activities of the population, it was allocated based on this population ratio. 

3.3.2 Emissions Allocation Based on Land Area 

A land area weighted emission ratio was developed using U.S. Census geographic data and/or 

Arizona Commerce Authority data. 1

<http://www.azcommerce.com/doclib/commune/Santa Cruz%20county.pdf> 
miles. The land area for the Nogales NA is 76.1 square miles. The ratio of Nogales NA land area 

to the Santa Cruz County land area is calculated by dividing 76.1 by 1,237.6, which equals 

.061490 or 6.15 percent. 

For a spatiai allocation of county-level emissions to the Nogales NA based on weighting by land 

area, the county-level emissions were multiplied by 6.15 percent to calculate the emissions for the 

Nogales NA. Some source categories, such as agricultural emissions, are likely to be 

proportional to land area; consequentiy, they are logically allocated by the land area ratio. 

3.3.3 Point Source Emissions Identification Within the Nogales NA 

To confirm whether specific point sources in the Santa Cruz County emissions inventory should be 

included in the Nogales NA inventory, ADEQ used facility supplied location information which was 

verified by visual inspection through aerial images, such as satellite photography within ArcGIS. 

These source categorries are discussed below. 

® Fuel Combustion - Electric Generation - Natural Gas. A power plant, Valencia Power, is 

located within the nonattainment area (Table 4.4). 

o Aircraft - The only airport in the County, Nogales International Airport, is within the 

nonattainment area (Table 4.4). 

® Waste Disposal - Institutional Incineration. A medical waste incinerator is located within 

the nonattainment area (Table 4.2). 

3.4 Methodology for Projecting the 2010 Emissions Inventories 

Nonattainment Area and County population estimates were covered in detail in Section 2.2 

Population and Urbanization. These values were used to estimate population growth rates within 

the NA between the year of the most recent National Emission Inventory, 2008, and the chosen 

year for the currently presented emission inventories, 2010 (1.1 % growth rate). Where 

appropriate, this growth rate was used to estimate emission growth between 2008 and 2010 

within the NA. 

For the 2010 base year emission inventories, ADEQ utilized the following assumptions: 

Source categories tied to economic activity were not grown between 2008 and 2010 due 

to the continued economic recession during this period; 

Source categories that track with population growth will be estimated at the same growth 

rate of 1.1 percent from 2008 to 2010; and, 

Major point sources were found to contribute less than 1.3% of total nonattainment area 

emissions for all pollutants for 2008. Considering this information along with the 

sustained economic downturn between 2008 and 2010, ADEQ felt it safe to assume no 

emissions growth between 2008 and 2010. 

Emissions from On-road mobile sources were projected from 2008 to 2010 as presented in 

Section 3.2.1. 
4 2008 Emissions Inventory and Discussion 

The County emissions inventory and Nogales NA allocation results are shown in Tables 4.1, 4.2, 

4.3 and 4.4. 

4.1 Review and Evaluation of Emissions Estimates 

The 2008 estimated rate of PM2,5emissions from road and other construction may be high because 

the emissions estimate does not reflect the full magnitude of the downturn in the real estate sector of 

the economy. It is likely that this downturn is a temporary situation and it may be expected that 

these emissions would resume at a higher rate once the real estate economy improves. As a result, 

this emission rate is conservative and is based on the best estimates of construction activity 

available at this time. 

Neither ADEQ nor EPA could identify exact locations of agricultural activities and prescribed 

forest burning. While it is appropriate to apply a land ratio method for assigning County-level 

agricultural emissions to the NA, this may underestimate emissions given that intensive 

agricultural activity is likely to occur on private land, located primarily in the nonattainment area, 

as opposed to the public lands composing a large proportion of the remaining County. The ratio 

of the NA area to the area of the county was found to be 6.15 percent (See Table 3.2). Thus, the 

NA agricultural activity emissions were estimated as only 6.15 percent of countywide emissions. 

While ADEQ recognizes the area allocation used may result in an underestimation of emissions 

from agricultural sources, ADEQ was unable to identify a more accurate method for allocation. 

An error was discovered in the 2008 NEI Area (non-point) data. The entry for "Misc. Area 

Sources, Ag. Production - Livestock, Swine" reported total NH 3(Ammonia) Emissions of 209.88 

tons per year. ADEQ reviewed the total for Hogs and Pigs for Santa Cruz County from the 

USDA1gand found a total of only 18 reported hogs and pigs in the county for the year of 2007. 

In the absence of more recent agricultural census data, ADEQ assumes this number, and thus 

agricultural emissions from Swine will not change substantially between 2008 and 2010. Doorn 

et al. (2002) determined a NH3emission factor for North Carolina swine of 7 kg/animal/yr 19 

This emission factor was compared by Doorn et al. to emission factors developed by Battye et al. 

(1994)20, Bouwman and Van Der Hoek (1997) 21 , and EMEP/CORINAIR (AEIG, 1998) 22 which 

ranged between 2.5 and 6.0 kg/animal/yr. For comparison, while EPA does not list emission 

factors for livestock in AP-42, EPA used emission factors for swine when developing the 2002

NEI of 2.7 — 3.3 kg/animal/yr. Assuming a conservative emission factor of 7 kg/animal/yr, this 

would yield emissions of 0.14 tons annually, a negligible amount. Therefore the entry of 209.88 

tons per year for swine was removed from Table 4.2. 

Another error was found when running the MOVES model for on-road vehicle emissions. NH 3 

emissions for "On-Road Gasoline Off-Network" and "On-Road Diesel Off-Network" source 

categories resulted in totais of 0 tons per year in both cases when using the EPA provided local 

database and the EPA national default database (Table 4.3). This is assumed to be a potentiai 

error within the calculation of NH 3emissions within the MOVES model since the same value was 

found to be reported in the 2008 NEI for Santa Cruz County. 

An error was previously found in the 2008 NEI for Cochise County which was also applicable to 

Santa Cruz County. The error was for surface mining, which showed a value of 761.11 tons per 

year for PM Io . The 2008 NEI for Santa Cruz County showed an identical value of 761.11 tons per 

year for PM lo. It was also found that all 15 Arizona counties had a surface mining value of 761.11 

tons per year for PM IO . ADEQ assumes that EPA divided the total surface mining emission value 

for the state by 15 and apportioned the results (761.11 tons per year for PM IO) to each county. 

ADEQ will work with EPA to correct the 2008 NEI data. Upon further investigation, ADEQ was 

unable to identify mining activities located within Santa Cruz County. Consequently, the related 

PM2. 5emissions for this source were not included in the non-attainment area estimates. 

4.2 Overall Assessment 

The 2008 NEI and the AEIS, along with emission estimates generated from MOVES, provide a 

comprehensive emission inventory for Santa Cruz County based on the best methodology and 

source data available at the time the inventory was developed. In allocating these County-wide 

emissions to the Nogales NA, ADEQ has used reasonable and conservative assumptions to produce 

a current, accurate, and comprehensive Nogales NA 2008 PM 2 , 5emissions inventory. Tables 4.1 

through 4.4 provide emissions allocations from the County level to the NA. "Pop" allocations are 

based on population allocations as outlined in Section 3.3.1, "Area" allocations are based on the 

methodology outlined in Section 3.3.2, and "Loc" allocations are emissions determined to originate 

from sources found within the nonattainment area.

5 2010 E><nissions Inventories 

5.1 Overview 

Since the Nogales NA met the PM2 , 5NAAQS based on ambient monitoring data from 2009-2011, 

ADEQ selected 2010 to serve as a representative emissions inventory for the purpose of the 

State's required PM2.5 plan submittal. The current SIP characterizes emissions levels for PM2.5, 

NH3, NO,, S02, and VOCs. Because 2008 is the year of the most current and complete nationai 

emissions inventory, ADEQ chose it as the base year for estimating the Nogales PM 2,5SIP 2010 

emissions inventories. Tables 5.1 through 5.4 provide NA emissions projections between the years 

of 2008 and 2010. "NG" refers to those sectors which are expected to experience no growth 

between 2008 and 2010; "Pop" projections are based on the population projection methods outiined 

in Section 3.4; "MOVES" projections are based on the methodology outlined in Section 3.2.1, and 

"Loc" projections are projections for identifiable source locations expected to maintain constant 

emissions between 2008 and 2010. 

The 2010 emissions inventories results are shown in the tables below. An emissions inventory for 

2008 was also included as it served as the starting point for the 2010 inventories.

6 Discussion and Conclusion 

The previous sections outlined the assumptions utilized to estimate emissions of NH 3 , NO,, 

PM2, 5 , S02, and VOCs for all source categories identified within the Nogales NA for the years 

2008 and 2010. A projected NA population growth of 1.1% between the years of 2008 and 2010 

has resulted in stagnant or siightly increasing estimated emissions for ail pollutants in all sectors 

except On-road Mobile Emissions (Table 6.1). In particular, population increases have resulted 

in increased emissions in the following sectors: construction; mobile brake wear, tire wear, and 

dust re-entrainment; waste disposal; and fuel burning. Despite these population based increases 

in emissions, a decrease in Mobile emissions between 2008 and 2010 resulted in a net decrease in 

total emissions for all pollutants. The On-road Mobile Emission decreases are primarily 

attributable to advances in motor vehicle control technologies and fuel efficiency.

Subject: Re: Nogales Emissions Inventory and MOVES 

Good morning Ryan. 

I checked my notes from our conversation last April and agree with your summary about how to 

proceed with the PM emissions inventory development using MOVES. I wouid just note that the 

reason for using population increase between 2008 and 2010 (as described in the #3 

recommendations below) is that VMT or related data (which might be more accurate than 

population) is not available. 

Please let me know if you have questions or need other information. 

Best,

Jeff, 

As ADEQ is currently in the final stages of completing the Emission Inventory (EI) for the 

Nogales, AZ Non-Attainment Area, we wanted to confirm the alternative methods you proposed 

for estimation of on-road mobile source emissions using MOVES were acceptable for the PM2.5 

Inventory development. On 4/30/2012 you and I spoke on the phone regarding the following 

issues with MOVES on-road mobile emission estimation using the Santa Cruz county database 

that was suppiied to ADEQ by EPA ("c04023y2008_in20100329"): 

1) 2008 S02 MOVES emissions were under-caiculated as 0 tons. 

45 
2) 2008 VOC MOVES emissions were over-calculated as 40,000 tons. 

3) The 2010 specific data was not included within the supplied database making ADEQ 

unable to run MOVES for this year. 

A more accurate dataset was unavailable from Santa Cruz County or ADOT. Upon discussing 

these issues with you, the following recommendations/agreements were made regarding how to 

proceed with PM2.5 EI development: 

1) 2008 S02 emissions should be calculated using the National, default database within 

MOVES. 

2) 2008 VOC emissions should be calculated using the National, default database within 

MOVES. 

3) 2010 emissions should be grown from 2008 MOVES results based on population increases 

within the Non-Attainment Area over the same time period. 

Please confirm that these alternative methods of MOVES emission calculation are acceptable for 

the finalization of the Nogales, AZ PM2.5 EI. If these methods are not acceptable, please advise 

on what steps should be taken to compensate for the above listed MOVES County database 

deficiencies. 

Thanks, 

Ryan Templeton

Dear Mr. Massey: 

Thank you for your submission of the Finai Report on the State of Arizona Air 

Monitoring Network Plan for the Year 2010. We have reviewed the submitted document 

and have found that it is complete, informative, very detailed and meets all of the 

requirements for annual network plans as required by our regulations set forth under 40 

CFR Part 58.10. While this letter serves as official approval of the.annual network plan, it 

does not constitute approval of the system modifications that are proposed in the plan for 

the future. We will continue to work with your district to review system changes as they 

proceed. 

Enclosed, please find our comments on the plan. If you have any questions 

regarding this letter or the enclosed comments, please feel free to contact me at (415) 

972-3851 or Michael Flagg at (415) 972-3372. 

Sincerely,

Comments on 2010 ADEQ Network PIan 

Please update next year's annual network plan to reflect the following comments: 

• The monitor/site tables for Pb, PMIa, and PM2,5 on pages 66-70 in should include 

the specific dates for the last two semi-annuai flow audits should be included in 

each applicable site report. 

• The monitor/site tables for PM2,5 should include the date of the last PEP audit 

performed. 

• The monit6r/site tables for the gaseous pollutant on pages 62-65 should contain 

information pertaining to the residence times, probe material used, and the date of 

the last NPAP audit performed. 

• The Hayden Old Jail monitor/site table on page 65 states that the S02 monitor 

operating at this site is part of the SLAMS network, while the site is also 

described as a part of the Source Compliance Monitoring Network in Table 4.7-1 

on page 25. Please clarify the characterization of the S02 monitoring at this site. 

• The monitoring sites in Miami are characterized as part of ADEQ's SIP sites and 

the.Source Compliance Monitoring Network. Please clarify the characterization of 

monitoring at these sites. Also, Appendix A and D should include information 

pertaining these sites. 

• Section 4.0 should include a section describing the required Pb monitoring 

requirements. For example, Pb monitoring at Globe Highway should not be 

considered part of the Source Compliance Monitoring Network (Table 4.7-1) 

since Pb monitoring at this iocation is required by the CFR not a PSD permit 

requirement. This section should also describe the Pb monitoring location recently 

established in Miami, AZ.

11 Amanda Stone: Good afternoon, thank you for coming. Even though there is an empty room for 

12 a little bit. I now open hearing on the proposed Arizona State Implementation P1an Revision for 

13 the Nogales PM2 , 5Nonattainment Area. 

14 

15 It is now Tuesday, September 3, 2013; at 1:35 p.m.. The location is the City of Nogales Council 

16 Chambers, 777 N. Grand Ave, Nogales, AZ 85621. 

17 

18 My name is Amanda Stone, and I have been appointed by the Director of the Department of 

19 Environmental Quality (ADEQ) to preside at this proceedings. 

20 

21 The purpose of this proceeding is to provide the public an opportunity to: 

22 

23 (1) hear about the substance of the proposed SIP revisions; 

24 (2) ask questions regarding the revisions; and, 

25 (3) present oral argument, data and views regarding their revisions in the form of comments in 

26 the form of comments on the record. 

27 

28 John Englander is here representing ADEQ from the Air Quality Division, State Implementation 

29 Plan Section. 

30 

1 
1 Public notice appeared in the Nogales International and on ADEQ's website beginning August 

2 2, 2013. Copies of the proposed SIP revision were made available at the ADEQ Public Records 

3 Center and ADEQ's website beginning August 2, 2013. 

4 

5 The procedure for making a public comment on the record is straightforward. If you wish to 

6 comment, you need to fill out a speaker slip, which is available at the sign-in table, outside the 

7 room here, and give it to me. Using speaker slips allows everyone an opportunity to be heard and 

s allows us to match the name on the official record with the comments. You may also submit 

9 written comments to me today. 

10 

11 Please note, the comment period for the proposed SIP revision ends today, September 3, 2013. 

12 Al1 written comments whether they were sent via U.S. mail or via e-mail or via FAX must be 

13 postmarked and or received by ADEQ by 5:00 p.m. today. 

14 

15 Comments made during the formal public comment period are required by 1aw to be considered 

16 by ADEQ when preparing the final SIP. This is done through the preparation of a responsiveness 

17 summary in which the Department responds in writing to written and oral comments made 

18 during the formal public, during the formal comment period. 

19 

20 The agenda for this hearing is simple. First, we wi11 present a brief overview of the proposed 

21 revision to the SIP. 

22 

23 Second, I will conduct a question and answer period. The purpose of the question and answer 

24 period is to provide information that may help you in making comments on the proposed 

25 revision. 

26 

27 Thirdly, I will conduct the oral comment period to ca11 speakers in the order that I have received 

28 their speaker slips. 

29 

I 
1 Please be aware that any comments at today's hearing that you want the Department to formally 

2 consider must be given either in writing or on the record at today's hearing during the oral 

3 comment period of this proceeding. 

4 

s At this time, Mr. Englander will give a brief overview of the proposal. 

6 

7 

8 

9 John Englander: The Nogales Non Attainment Area was designated nonattainment for the 2006 

10 PM2.5 National Ambient Air Quality Standards (or NAAQS) based on monitoring data from 

11 2006-2008. PM2.5 conditions in the region have improved since that time. On January 7, 2013, 

12 subsequent to the designation, EPA finalized a clean data determination for the Nogales planning 

13 area under the C1ean Data Policy. This action suspended requirements to submit State 

14 Implementation Plan (or SIP) elements related to attainment of the NAAQS including reasonable 

15 further progress milestones, attainment demonstrations, control measures, and contingency 

16 measures. This state implementation plan revision addresses the remaining Clean Air Act 

17 requirements applicable to the Nogales Non Attainment area. 

18 

19 The document outlines general economic and demographic information of the nonattainment 

20 area and Santa Cruz County, the Clean Air Act requirements for a Nonattainment Area Plan, a 

21 description of the air quality monitoring network and recent ambient air quality data for the area, 

22 an emissions inventory, a description of new source review and permitting requirements for the 

23 area, and general conformity requirements. 

24 

25 

26 

27 Ms. Stone: This concludes the explanation period of this proceeding on the proposed revision to 

28 the SIP. 

29 

30 

31 

3 
1 Are there any questions before we move to oral comment period? 

2 

3 Hearing none, this concludes the question and answer period of this proceeding on the proposed 

4 revision to the SIP. 

5 

6 

7 

8 I now open this proceeding for oral comments. 

9 

10 We received no speaker slips, so this concludes the oral comment period for this proceeding. 

11 

12 

13 

14 If you have not already submitted written comments, you may submit them at this time. Again, 

15 the comment period for this proposed revision to the SIP ends today, September 3, 2013, at 5:00 

16 p.m. 

17 

18 Thank you.
