### EXECUTIVE SUMMARY

The Nogales PM 2

. 5



### Nonattainment 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

. 5 

### National 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 PM 2

### 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
. 5 National 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
. 5 standard and retained the PM, o standard as a"coarse" standard protecting both health and welfare. The 24-hour PM 2

. 5 standard was set at 65 μg/m 3 and the annual standard was established at 15 μg1m 3 . Rather than using a graduated scale of PM Io nonattainment area designations, EPA designated PM 2

. 5 nonattainment 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 PM 2 , 5 standards (70 FR 19844; April 14, 2005). 1 Nogales, Arizona was not designated nonattainment for the 1997 PM2.5 standard.

1.1.2 2006 Fine Particulate Matter NAAQS While the 1997 PM 2 , 5 standards 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 PM 2 , 5 on October 17, 2006; see 71 FR 61144 EPA lowered the 24-hour standard from 65 μg/m 3 to 35 μg/m 3 and retained the 1997 annual standard of 15 μg/m 3 . A comparison of the 1997 and 2006 PM 2 , 5 standards 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. Z The 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.

### 1.5 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. 6 An 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.)

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 , 5 24-hour standard. Arizona recommended the same boundaries as the existing PM io nonattainment area (see Figure 1.1). 10 EPA 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 PM 2

. 5 NAAQS. On October 30, 2012, EPA proposed to determine that the Nogales NA had met the 24- hour PM 2

. 5 NAAQS 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 , 5 nonattainment 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 PM IO nonattainment areas, under a recent court decision, these same statutory requirements also apply for PM 2 , 5 nonattainment areas. 12 The suspended CAA elements related to attainment of the 2006 PM2.5 NAAQS and the Clean Data Determination are noted in the table below.

10 ADEQ, "Technical Support Document for Recommendation that the Nogales, Arizona Area Be Designated as a PM 2.5 Nonattainment Area". Submitted to EPA on December 3, 2007. <http://www.epa.goy/pmdesignations/2006standards/rec/letters/09 AZ rec a2.1)df>

12 Natural Resources Defense Council v. EPA, 706 F.3d 428 (D.C. Cir. 2013) (Petitioners challenged EPA's decision to promulgate the 1997 PM2. 5 NAAQS 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 PM 2 , 5 Standards 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 PM 2 , 5 monitoring in the Nogales NA is to collect the data necessary to compare ambient air quality values with the PM 2

. 5 NAAQS 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 13 and 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. 14 In 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

continuously operating FEM BAM to serve as the primary PM 2

### monitor to be compared to the NAAQS. Historically, ADEQ operated collocated filter-based PM 2 , 5 federal 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 , 5 at the Post Office site since February 2004; data collected by this monitor were not used to determine compliance, but is usedto 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 PM 2

. 5 instruments 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 , 5 monitor 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 , 5 monitor from 1999- 2012. Compliance with the PM 2
. 5 NAAQS is determined based on the 98` h percentile 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 °d 24-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 PM 2
. 5 NAAQS of 35 μg/m 3 since 2007.

### 134.0 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.

### precursors 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.

### 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.

# I Introduction

1.1 Purpose This document provides a PM 2 , 5 emission 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
. 5 State Implementation Plan (SIP) for the Nogales NA, located in Santa Cruz County, Arizona. Since the Nogales NA met the PM-1. 5 Nationai 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
PM 2
. 5 refers 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 PM 2 , 5 include fugitive dust, open burning (including wild fires), and, to a greater extent, fuel combustion sources and mobile source exhaust. There are two types of PM 2

. 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 N11 3 ). 

### 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. 1 The mean elevation in Nogales, Sonora is 4,265 feet (Instituto Nacional de Estadistica Geografia e Informatica, 2005). Z At 5,380 feet, the highest elevation in Nogales, Sonora is the Cerro de los Nogales (Nogales Hill).

### 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 3 and 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). 6 This 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 31,334 7 (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.

### 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 , 5 and 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 PM 2

. 5 NAAQS. 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 PM 2 , 5 , NH 3 , NO X , S0 2 , 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 (PM IO and PM 2

. 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. 9 On 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. 10 MOVES2010a 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.

10 See 75 FR 9411 (March 2, 2010)

### 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).
~ 1

### A 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).
PM 2 , 5 emissions 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 2 and 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.

### 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 ' The land area for Santa Cruz County is 1,237.6 square

### 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 PM 2

, 5 

### emissions 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 USDA 1g and 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 NH 3 emission 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 3 emissions 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 PM 2

. 5 

### emissions 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

# 5 2010 E><nissions Inventories
5.1 Overview Since the Nogales NA met the PM 2 , 5 NAAQS 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, NH 3 , 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 , 5 SIP 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,, PM 2

, 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.

# Appendix D: Email from EPA specifying Re: Nogales

Emissions Inventory and 1VIOVES From: Jeffrey Buss [Buss.Jeffrey@epamail.epa.gov ] Sent: Thursday, May 31, 2012 8:32 AM To: Ryan C. Templeton Cc: Diane Arnst; Steve M. Calderon; Colleen McKaughan; Phil B. Denee; Jerry Wamsley; Theresa E. Rigney 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, Jeffrey Buss U.S. EPA Region 9 415-947-4152

From: "Ryan C. Templeton" <Templeton.Ryan@azdeq.gov > To: Jeffrey Buss/R9/USEPA/US@EPA Cc: Colleen McKaughan/R9/USEPA/US@EPA, Diane Arnst <Arnst.Diane@azdeq.gov >, Jerry Wamsley/R9/USEPA/US@EPA, "Theresa E. Rigney" <Rigney.Theresa@azdeq.gov >, "Steve M. Calderon" <Calderon.Steve@azdeq.gov >, "Phil B. Denee" <Denee.Phil@azdeq.gov > Date: 05/31/2012 08:08 AM Subject:

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 Environmental Engineer Specialist Air Quality Division Arizona Department of Environmental Quality rct@azdeq.gov (602) 771-4230

Eric Massey, Director Air Quality Division Arizona Department of Environmental Quality 1110 W. Washington St. Phoenix, AZ 85007 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,

Printed on Recycled Paper

### 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.

### 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

31 

### 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
