BINATIONAL PREVENTION AND EMERGENCY RESPONSE PLAN 

FOR THE REGIONAL MUNICIPALITY OF 

NOGALES, ARIZONA, UNITED STATES OF AMERICA 

AND NOGALES, SONORA, MEXICO 

FORWARD 

The U.S. and Mexico signed a Joint Contingency Plan (JCP) that established a foundation for 

cooperative efforts regarding preparedness, mitigation, response and prevention of hazardous 

substance releases in the border area. The JCP serves as an umbrella plan which set forth a 

broad framework for planning efforts for 14 pairs of adjacent cities on each side of the U.S.­

Mexico border. The federal governments of the United States of America and Mexico have 

recognized the advantages for each city to share resources and manpower in times of national 

disasters. So too, the municipalities of Nogales, Arizona, and Nogales, Sonora recognize their 

need to cooperate with each other in times of local disasters and to take measures to reduce 

risks and mitigate incidents. 

In the event of a disaster of serious proportions that may require a great deal of coordination 

and cooperation, a plan between the two cities to prevent and respond to disasters will better 

ensure a full and effective utilization of resources and manpower essential to protect the public 

health, safety, and environment within the border area. 

This Binational Prevention and Emergency Response Plan identifies vulnerable areas and 

potential sources of risk and recommends some key risk reduction measures. The plan also 

contains a complete contact directory of names and organizations that are important to 

prevention, preparedness, response to and mitigation of incidents involving hazardous 

substances, fires, natural disasters, and events involving weapons of mass destruction. 

When a disaster has been declared, this Binational Prevention and Emergency Response Plan 

will not supersede any local, state, or federal authorities or plans in effect. This plan will 

complement existing local, state, regional, and federal plans. 

All regional and local municipal elected and appointed officials with emergency 

responsibilities should be fully knowledgeable of the content of this document and be prepared 

to fulfill their responsibilities when requested and when capable.

BINATIONAL PREVENTION AND EMERGENCY RESPONSE PLAN 

UNDERSTANDING ON COOPERATION BETWEEN THE CITIES OF NOGALES, 

ARIZONA, AND NOGALES, SONORA, FOR PREPAREDNESS FOR AND RESPONSE 

TO ENVIRONMENTAL AND DISASTER EMERGENCIES CAUSED BY RELEASES, 

SPILLS, FIRES, EVENTS OF WEAPONS OF MASS DESTRUCTION OR EXPLOSIONS 

OF HAZARDOUS SUBSTANCES IN THE INLAND BORDER AREA 

The cities of Nogales, Arizona, and Nogales, Sonora, have agreed to provide mutual 

cooperation to effectively reduce the risk of and respond to threats to the public health, safety 

and welfare of the communities due to accidental releases of hazardous materials into the 

environment, and any and all disasters and event involving weapons of mass destruction. This 

understanding is to reinforce the cooperation between the cities to be able to prevent and 

respond more efficiently to these events. 

The following statement of principles is intended to serve as a guide to emergency response 

authorities in both cities. 

1. The agencies of both municipalities charged with emergency responsibilities will seek to 

ensure that in areas of common concern, plans of the two municipalities for the emergency 

use of manpower, material resources, supplies, systems, and services shall, where feasible 

and practicable, be compatible and involve mutual training. To this end, a Binational 

Emergency Planning Committee (BEPC) will be established and meet regularly. The BEPC 

will address planning and preparedness activities and conduct an annual binational exercise 

to evaluate and improve the coordination of this Sister City plan. 

2. The city providing the assistance will supervise their necessary personnel and assigned 

equipment. The group receiving aid will have authorized persons to provide general 

directions related to the work. The potentially responsible party (PRP) for the spill receiving 

the assistance will be responsible for providing the responders with the necessary materials, 

food, shelter, temporary housing, gasoline and lubricants for the equipment and any other 

such items needed to respond adequately. 

3. It is mutually agreed that this understanding does not relieve any of the mentioned parties of 

the obligation for providing protection against fires or other emergencies, according to their 

respective jurisdictions, and to use reasonable diligence in maintaining all equipment in 

adequate condition according to industry standards. The only representatives designated to 

activate the Bi-National plan and/or to make the decision to render aid to the Sister City are 

the Fire Chief in Nogales, Arizona, the Fire Chief of Nogales, Sonora, and/or the Director of 

Civil Protection in Nogales. Each Sister City may decide not to render aid, depending on 

each incident, if its resources are not capable of meeting obligations in its own jurisdiction. 

4. The municipalities involved in this understanding will not be required to pay compensation 

to the other for services rendered.

5. Each party agrees to hold each other harmless from acts which may arise resulting in any act 

or omission of any party’s personnel during such time that said personnel are serving in the 

jurisdiction of any party for assistance pursuant to the terms of this understanding. 

6. This understanding shall not be construed as an agreement for the benefit of any third party, 

taking effect at the time of execution and will continue until rescinded. 

7. Every two years the parties will examine the present understanding in light of its application 

in order to decide if it must be modified. Nevertheless, the parties may examine this matter 

and propose changes to the other parties by personal service or certified mail. Changes will 

be considered effective starting on the date of the amendment’s signing by all parties. 

8. Any party to this understanding may withdraw at any time giving thirty days prior written 

notice to all the parties. On the thirty-first day after the notice, such withdrawal will become 

effective. 

9. Any party may change its service address by five days written notice to each of the other 

parties. On the sixth day after the notice, such change of address is effective. 

10. Notice of withdrawal and change of address shall be served by personal service or by the 

respective party’s Postal Service certified mail addressed to:

BINATIONAL PREVENTION AND EMERGENCY RESPONSE PLAN 

STATEMENT OF PRINCIPLES CONCERNING 

UNITED STATES - MEXICO COOPERATION 

ON EMERGENCY RESPONSE PLANNING
 

The following Statement of Principles is intended to serve as a guide to emergency response 

authorities in both cities. 

1. Nothing in this understanding shall derogate or diminish the application of Mexican law in 

Mexico or United States law in the United States. However, the authorities of either country 

may request the assistance of the other country in seeking appropriate alleviation if the 

normal application of law in either country might lead to delay or difficulty in the rapid 

execution of necessary emergency response measures. 

2. The agencies of both governments charged with emergency response responsibilities will 

seek to ensure that in areas of common concern, plans of the two governments for the 

emergency use of manpower, material resources, supplies, systems and services shall, where 

feasible and practicable, be compatible and involve mutual training. The decision to render 

aid to the Sister City rests ultimately with the Fire Chief of Nogales, Arizona, Fire Chief of 

Nogales, Sonora and/or the Director of Civil Protection of Nogales, Sonora. Each Sister City 

may decide not to render aid, depending on each incident, if their resources are not capable 

of meeting obligations in their own jurisdiction. 

3. Each government will use its best efforts to facilitate the movement of evacuees, refugees, 

emergency response personnel, equipment or other resources into its territory or across its 

territory from one area of the country to another when such movement is desired to facilitate 

emergency response operations in either country. To this end: 

a. To the maximum extent permitted by law and regulation, the Government of the 

United States and the Government of Mexico, during a period of an emergency, will 

use their best efforts to reduce to a minimum any delays which might otherwise be 

caused by border crossing requirements. Both governments will also use their best 

efforts to ensure that emergency response equipment, facilities, and supplies may be 

used effectively and to mutual advantage in joint efforts, tests, preparations and 

exercises. 

b. The emergency response agencies of both governments will consult together to 

identify and remove any serious potential impediments to cross border assistance, 

emergency operations and the cross border flow of commodities for emergency 

response. Unresolved problems will be reported to the Joint Response Team for 

appropriate action. 

4. For the purpose of emergency relief, health and welfare services, each government will use 

its best efforts to ensure that those citizens or residents of the other country on its territory 

are treated in a manner no less favorable than its own citizens. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 7 

March 17, 2000 

Revised July 2005 
 

5. The Binational Committee has the responsibility to facilitate an inventory list of all 

equipment to be utilized for the emergency to United States and Mexico customs at the time 

of entry into either country. 

6. The general administration of Mexican customs, which is under the direct jurisdiction of the 

Secretaría de Hacienda y Crédito Público will implement policies and procedures that will 

facilitate the legal entry of equipment and personnel responding to the emergency, as it is 

stipulated in the Plan Conjunto de Contingencias México-U.S. (U.S. Mexico Joint 

Contingency Plan). 

7. Each government will use its discretionary powers as far as possible to avoid a levy of any 

national tax on the services, equipment and supplies of the other country when the latter are 

engaged in emergency response activities on the territory of the other, and will use their best 

efforts to encourage state, provincial, and local authorities to do likewise. 

8. When transportation, communication and related facilities and equipment which are subject 

to the control of one government are made available for emergency use to the other 

government, the charges to that government shall not exceed those paid by similar agencies 

of the government making these resources available. To this end, mutually acceptable 

arrangements shall be worked out as necessary by the two governments. 

9. In its emergency planning, each government will include provisions for adequate security 

and care for the personnel, equipment, and resources of the other country entering its 

territory by mutual agreement in pursuance of authorized emergency response activities. 

Such provisions will also ensure access to supplies necessary for their return. 

10. Transportation and other equipment originating in one country at the onset of an emergency 

may be temporarily employed under mutually agreed terms by the appropriate authority of 

the country in which the equipment is located. 

11. Perishable or other readily consumable supplies located in one country at the time of an 

emergency but owned by parties in the other country may be disposed of under mutually 

agreed terms by the appropriate emergency response authorities of the two countries. 

12. Each government will call to the attention of its state, provincial, local or other authorities in 

areas adjacent to the international border the desirability of achieving compatibility in 

emergency response planning between the United States and Mexico. For the purpose of 

achieving the most effective emergency response planning cooperation possible between the 

United States and Mexico, each government will, in a manner consistent with national plans 

and policies, also encourage and facilitate cooperative emergency arrangements between 

adjacent jurisdictions on matters falling within the competence of such jurisdictions.

1.0 INTRODUCTION 

In January 1988, the United States of America and the United Mexican States signed the Joint 

United States of America - United Mexican States Contingency Plan for Accidental Releases of 

Hazardous Substances along the Border. The Joint Contingency Plan (JCP) provides a framework 

for cooperation between Mexico and the United States in response to an accidental chemical release 

incident that may pose a significant threat to both countries, or that affects one country to such an 

extent that assistance is necessary. As a part of the preparedness and response component of the 

Joint Contingency Plan, a Sister Cities program was established, which pairs 28 cities along opposite 

sides of the U.S./Mexico border from California through Texas. This program calls for the 

preparation of Sister City Hazardous Materials Incident Contingency Plans for each of the 14 pairs 

of cities. Figure 1 shows the U.S./Mexico Sister Cities. 

This document is the joint contingency plan for the Nogales, Arizona, and Nogales, Sonora area. It 

represents a summary of the hazardous materials, natural disasters, and events involving weapons of 

mass destruction notification and response protocols in place for Nogales, Arizona, and Nogales, 

Sonora, and other jurisdictions, as promulgated by local plans. This plan specifically addresses the 

requirement under the Joint Contingency Plan to prepare Sister Cities plans. It is not intended to 

replace or supplant any other plans in effect in the region, but is designed to aid in a binational 

response to a hazardous materials incident, natural disasters, and WMD events that may affect the 

border. 

This plan at no time usurps existing federal, state, county, regional, or municipal plans within the 

jurisdictional boundary addressed by this plan. 

If the region affected declares an emergency under this plan to be in effect, the municipality affected 

will, subject to its own disaster plan, inform state and federal officials, as identified in their 

respective plans. This plan is activated for the short term only and it will provide specifics for the 

coordination of resources and equipment. 

The initial and prime responsibility for providing immediate assistance rests with the city, county or 

regional government affected. It is at this level that services such as fire, police, health, and social 

services, public works, and public utilities are located. An emergency under this plan may be 

declared when (1) a city, county or region so requests the head of government; (2) the emergency, 

due to geography, may dictate evacuation into a neighboring region; (3) the municipality, county or 

region affected may request mutual aid support, supplying manpower, resources, social services, 

fire, public works, emergency health services, and other specialized expertise as deemed necessary 

by the affected municipality; or (4) the emergency may affect a neighboring municipality, county, or 

region. 

The plan promotes timely and effective coordination and response between private sectors (industry, 

other potentially responsible parties and citizens) and public sectors (local, state, and federal 

governments). The primary objective of the plan is to develop communication capabilities and 

encourage coordination of independent response resources acting within local jurisdictions. The 

plan aids understanding of regional capabilities and resources and provides a background for 

Binational Prevention and Emergency Response Plan

March 17, 2000 

Revised July 2005 
planning coordination with state and local officials. Appendices H and I present Abbreviations and 

Acronyms, and Definitions, respectively. 

Secondary objectives include the development of notification systems between response 

organizations in the different cities, and developing international mutual aid agreements. The 

secondary objectives are being addressed through ongoing cooperative efforts between local 

planners in Nogales, Arizona, and Nogales, Sonora, the Arizona Department of Environmental 

Quality, the United States Environmental Protection Agency (U.S. EPA Region IX), Mexican Civil 

Protection (Protección Civil), and PROFEPA (Federal Attorney General for Environmental 

Protection), Sonora. 

A directory of essential planning and response contacts is located in Appendix A. 

1.1 Nogales, Arizona - Nogales, Sonora Plan Area 

This plan covers the U.S./Mexico Sister City pair of Nogales, Arizona, and Nogales, Sonora 

(Figure 2). The Nogales, Arizona/Nogales, Sonora Sister Cities are also known as “Ambos 

Nogales.” The proximity of these two communities on the international border fosters constant 

exchange of American and Mexican culture. 

Nogales, Arizona is located in southwestern Arizona, Santa Cruz County, between latitudes 31_19’N 

and 31_23’N and longitudes -110_53’W and -110_58’W. Nogales, Sonora is located just south of 

Nogales, Arizona between the latitudes 31_14’N and 31_19’N. By highway, the Sister Cities are 

about 65 miles southeast of Tucson, Arizona, and 240 miles north of Hermosillo, Mexico. 

1.1.1 Physical Environment 

Ambos Nogales are in a mountainous setting at an altitude of 3,800 feet (1200 meters) above sea 

level. The climate is tropical with arid winters. During the summer, the humidity increases. The 

average annual high and low temperatures are 100°F and 30°F, respectively. The average summer 

temperature is 100°F while the average winter temperature is 48°F. 

Summer thunderstorms are the major source of precipitation. Yearly rainfall from 1986 to 2003 

ranged from 17.98 inches to 4.65 inches. The most rain in a given year occurred in 1990 and the 

most dry in 1999. Free-flowing surface water is rare. Table 1 below shows the average monthly 

high and low temperatures and average monthly precipitation for the City of Nogales, Arizona and 

for Nogales, Sonora for 2003 (Reference 2, Community Profile of Nogales, Arizona). 

The Santa Cruz River is the major river in the plan area. It originates in the mountains 80 miles 

southeast of Tucson, and flows south 15 miles before crossing into Mexico. After making a 40-mile 

loop to the west, it returns to the U.S. through Nogales, Arizona, then heads north to Tucson and to 

converge with the Gila River. 

The Nogales Wash is an intermittent stream that flows north from Nogales, Sonora through the 

center of Nogales, Arizona and empties into the Santa Cruz River.

1.1.2 Population 

The cumulative population of the plan area is about 363,491 people with 325,491 residing in 

Nogales, Sonora, and 38,000 residing in Nogales, Arizona. An additional estimated 16,000 people 

reside in nearby rural-urban areas, outside city limits. Nogales, Sonora has 116 areas and a total 

population of 325,491 (196.79 residents per square kilometer), of which 164,372 are men and 

161,119 women. Of the total population of Nogales, Sonora, 98.1 % live in urban areas. The 

population of Nogales, Sonora has a natural growth rate of 6.9%. The total metropolitan area 

population is approximately 325,491, and is increasing. 

1.1.3 Economy 

International commerce is an important part of Ambos Nogales. Nogales, Arizona is a major port of 

entry for winter fruit and vegetables from Sonora and Sinaloa (Reference 6). During the growing 

season, about 100 produce firms import up to 1,200 truckloads of produce daily with an estimated 

wholesale value of $20 million to $25 million. The retail value per year is estimated at $5.3 billion. 

In addition, 40% of Nogales, Arizona sales tax comes from nearly 50,000 Mexican shoppers 

crossing the border every day. Section 2.3 below has more details on the ports of entry. As a border 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 13 

March 17, 2000 

Revised July 2005 
town, Nogales, Sonora is included in the International Boundaries and Water Agreement (Convenio 

Internacional de Límites y Aguas). This program prevents the drilling of new water wells, which 

limits agricultural activities. Nogales, Sonora has only 21 wells for agriculture. Exporting cattle has 

become the most profitable industry, although profitability is limited by low calving. Nogales, 

Sonora has a great variety of establishments offering merchandise and services, including among 

others: mini-markets, grocery stores, hardware stores, furniture stores, curio shops, auto parts, 

restaurants, mechanic shops, automobile distributors. 

The area is home to one of the largest cooperative manufacturing (maquiladora) clusters along the 

U.S.-Mexico border. Approximately 90 maquiladoras are located in Nogales, Sonora. Appendix C 

is a list of the members of the largest maquiladora association in Nogales, Sonora. In 1992, there 

were about 43 maquiladoras. Most of the maquiladoras are assembly plants that bring in raw 

materials, add value to a product, and are taxed on the value added. Almost a third of these (31%) 

are involved in the electronics industry with nearly 15.5% in the medical industry. Section 2.1 

below discusses business facilities in more detail. 

1.1.4 Infrastructure 

Ambos Nogales have a binational agreement for wastewater treatment. The International 

Wastewater Treatment facility is located on the Arizona side at South Rio Rico Industrial Park. The 

municipal wastes of Nogales, Arizona are transported to Santa Cruz County Landfill, which is 15 

miles north of the city, off Interstate I-19 at the Calabasas Interchange. Roads, railroads, water, and 

wastewater are discussed further in sections 2.2, 2.4 and 2.5 below. 

1.1.5 Cultural Significance 

Strong commercial, cultural, and religious ties exist between these Sister Cities. Nogales, Sonora 

was incorporated as a Municipality in July 1884. Previously, in 1880, the Sonora Railroad Company 

(Compañía de Ferrocarril de Sonora) obtained authorization to establish a terminal station in a 

location within the Magdalena district international border area. Later, a border area customs office 

was authorized for the exact location of the train terminal station. Nogales, Sonora became a Villa 

in July 1889 and a City in 1920. Nogales, Arizona was established in 1880 and is site of the first rail 

connection between the U.S. and Mexico. It is the county seat in Santa Cruz County. Nogales, 

Sonora has served as a trading route and cultural exchange area for various cultures including the 

Anasazi, Hohokam and in the 1500's, the Pimas. In 1853, survey teams established the international 

boundaries that exist today. Business between the cities over the years has grown and is 

contributing to their collective growth and strengthened connections.

(Reference 7). 

1.3.2.2 State of Arizona Plans 

The State of Arizona Emergency Response and Recovery Plan (February 1998) addresses the 

consequences of any emergency or disaster where there is a need for state response and recovery 

assistance (Reference 3). The plan describes the methods that the state will use to assist local 

jurisdictions, mobilize resources and conduct cost recovery activities. 

The State of Arizona Hazardous Materials Response and Recovery Plan (1989) provides emergency 

management for a state response to a hazardous materials incident. It was developed by the Arizona 

Division of Emergency Management and the Arizona Emergency Response Commission and gives 

an overview of the roles and responsibilities of various state agencies. 

1.3.2.3 Federal Plans

2.0 HAZARDS ANALYSIS AND RISK REDUCTION 

Critical to emergency response and preparedness is an analysis of the hazards posed in the plan area 

and measures to reduce the risks from these hazards. This section identifies hazards and analyzes 

vulnerable human and environmental resources and associated risks. This section also addresses the 

jurisdictions’ recommendations and commitment to reduce the risks from these hazards. 

2.1 Fixed Facilities Using or Handling Hazardous Materials 

An initial assessment (profile) of fixed facility hazards is presented here. The profile is useful as a 

general overview of facilities and for the determination of additional data collection needs. 

2.1.1 Nogales, Arizona 

· Tier II Facilities 

Under EPCRA, facilities that have hazardous chemicals present on-site (above specified thresholds) 

must report those chemicals to state and local agencies, including the Nogales, Arizona Fire 

Department. They file a report known as a Tier II chemical inventory report. The report is due by 

March 1 of every year for all chemicals present on site during the previous calendar year. 

Appendix B is a list of all facilities that have filed Tier II reports in Santa Cruz County, Arizona, 

including the facility name and address, the identity and quantity of the chemicals, and facility 

contact information. The major chemicals of interest stored in Nogales, Arizona are propane, 

chlorine gas, and ammonia. Amerigas operates a 30,000 gallon liquid propane gas facility on 

Mariposa Road on the west side of the city. The city uses chlorine gas for drinking water treatment 

at several locations. Nogales Ice Company and Sierra Refrigerating Company use 1,800 pounds and 

2,200 pounds of ammonia for refrigeration, respectively. It is likely that other produce warehouses 

use ammonia for refrigeration, but have not filed Tier II reports. 

Steris uses ethylene glycol (74,000 pounds), ethylene oxide (3,200 pounds), nitrogen-cryogenic 

liquid (19,000 pounds), sodium hydroxide (1,300 pounds), and sulfuric acid (3,500 pounds). United 

Musical Instruments is a musical instrument manufacturing plant that uses hundreds of pounds of 

chromium and cyanide in a plating process. 

Additional hazardous substances stored at various facilities include fuels and oils. 

· Other Facilities 

There are about 2,600 businesses and five industrial parks in Nogales, Arizona. In general, when a 

new manufacturing plant opens in Nogales, Sonora, jobs in the distribution industry are created in 

Nogales, Arizona. Numerous produce warehouses are located in the city. Some use methyl bromide 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 19 

March 17, 2000 

Revised July 2005 
 

to ripen fruit, and ammonia for refrigeration. In addition to Amerigas, California Propane store 

propane near the border. So much growth has occurred along Mariposa Road that large businesses 

have difficulty obtaining adequate telephone lines from U.S. West. 

2.1.2 Nogales, Sonora 

· Maquiladoras 

Ambos Nogales is home to one of the largest clusters of cooperative manufacturing plants, known as 

maquiladoras, along the U.S.-Mexico border. Approximately 90 maquiladoras are situated in this 

region, most of which are identified in Appendix C. Figure 2 shows the industrial areas where the 

maquiladoras are located. These companies manufacture a variety of items, primarily computer 

equipment, power supply equipment, medical products, paper products, and home construction 

items. Nearly all of the maquiladoras are U.S.-based. The majority of the maquiladoras are in five 

industrial parks located between 4 and 7 miles (3 to 6 kilometers) south of the International 

Boundary (Figure 2). The newest industrial park is located where the new cargo access toll road 

connects with the Nogales-Hermosillo Highway. The transport and storage of hazardous materials 

and wastes associated with the maquiladoras is considered to be the highest risk under this plan. 

The maquiladoras generally have their own fire brigade and medical staff to handle emergencies. 

They are inspected by the federal government. They prepare contingency plans, but have not yet 

provided them to local authorities. Civil Protection, Nogales, Sonora, is currently in the process of 

collecting these plans. Currently, Civil Protection has contingency plans for 10 gasoline stations and 

2 recycling facilities. 

· Other facilities 

Aside from the maquiladoras, the primary locations for hazardous materials are plating shops, 20 

gasoline stations, 4 LP storage facilities, 3 LP stations and storage facilities, 2 ice plants, 1 bottling 

company, 1 underground natural gas pipe line. Also a PEMEX distribution and storage plant, 

FERROMEX railroad handling hazardous materials, commercial trucking with similar and other 

cargo, and 1 airport 

2.2 Transportation Systems 

Representative chemical transportation data are critical to the identification and analysis of a 

potential hazardous materials emergency. This section provides an overview of hazardous materials 

traffic in the plan area, and identifies additional data that should be collected and analyzed to create 

a comprehensive transportation hazards identification. Figure 3 highlights the major roads, 

hazardous intersections, railroads in the two cities. Figure 2 shows these features on a general map. 

2.2.1 Nogales, Arizona 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 20 

March 17, 2000 

Revised July 2005 
2.2.1.1 Roads 

The transportation corridors of Ambos Nogales are of strategic importance to both countries. Three 

major highways cross through Nogales, Arizona (Figures 2, 3). Interstate Highway 19 transverses 

the county from north to south. Its major intersection is at the Mariposa Road interchange. Also, 

State Highway 82 extends from the northeast corner of the county to the center of its southern border 

and intersects Grand Avenue (U.S. Route 89) in Nogales, Arizona. U.S. Route 89 runs from the 

eastern port of entry north along the east side of the city until it merges with I-19 just north of the 

city limits. Traffic from the western port of entry proceeds north then east along Mariposa Road 

(State Highway 189) to interchanges at I-19 and 89. Hazardous intersections are indicated on 

Figures 2 and 3, and are primarily intersections where trucks turn from one route onto another. 

The State of Arizona has adopted, as state law, the Federal Motor Carrier Safety Standards as 

recorded in 49 CFR Part 397.9 for routing hazardous materials. The law states that vehicles 

transporting hazardous materials must use preferred routes that avoid tunnels, bridges, and areas of 

dense population. 

The last comprehensive traffic study performed for Nogales, Arizona is too old to be of use. In 

1999, a more limited traffic study was completed for the purpose of locating a safety inspection 

facility. This study focused on traffic at the ports of entry and around the site where the inspection 

facility will be located. 

2.2.1.2 Railroads 

A major rail line runs through the center of Nogales, Arizona. The rail system is operated by Union 

Pacific. 

Along with other railroads and some (but not all) trucking companies, Union Pacific participates in 

Operation Respond. This computer program is linked to a master database by telephone. Keyed to 

numbers on the rail car, the program identifies the type of chemical in each car, the risks of each 

chemical, the precautions that should be taken, and other safety information. Using the North 

American Emergency Response Handbook, it provides emergency response information for the 

chemical. 

If chemical information is needed, the Nogales, Arizona Fire Department typically calls a telephone 

number operated 24 hours per day to obtain the shipping papers. 

2.2.1.3 Other Means of Transport 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 21 

March 17, 2000 

Revised July 2005 
Nogales, Arizona has a small international airport with a 7,200 foot runway. The Crucero Bus 

Service, and shuttles travel to Phoenix and Tucson. 

Smoke plumes from Nogales, Sonora sometimes drift to Nogales, Arizona. The smoke comes from 

landfill and trash burning, as well as the burning of insulation off copper wire to recover the copper. 

Sometimes the smoke is trapped in an inversion layer over the two cities. The smoke generally 

occurs on weekends and after 7 p.m. at night. The U.S. Public Health Service has been working 

with Public Works (Obras Públicas) to address this matter. 

One natural gas pipeline runs through Nogales, Arizona. Natural gas is distributed by Unisource. 

The tunneled Nogales Wash extending about one mile (1.7 kilometers) in the U.S. and three miles (4 

kilometers) in Sonora poses a potential risk of contaminant transport. 

2.2.2 Nogales, Sonora 

2.2.2.1 Roads 

There are two main roads through Nogales, Sonora (Figures 2, 3). Trucks use a private toll road 

west of the city to the port of entry. Private automobiles use the Nogales-Hermosillo Highway, 

which runs through the center of the city. The maquiladoras are concentrated around the major 

roads. 

2.2.2.2 Railroads 

Two major rail lines join in the heavily populated section of Nogales, Sonora (Figures 2, 3). The rail 

system is operated by Ferrocarriles Mexicanos (Ferromex). Like Union Pacific, Ferromex maintains 

information in a computer on the chemicals transported by rail. The railroad runs along one of the 

main roads, the Nogales-Hermosillo Highway. As discussed above, Civil Protection has access to 

information on chemicals shipped by rail through a computer system known as Operation Respond. 

East of Nogales, Sonora, the rail line runs parallel to the Santa Cruz River for 4-5 miles. This rail 

line is one of the main routes for the transport of about 25 tank cars of sulfuric acid every three days 

from two large copper mines in Mexico into the U.S. for use at precious metals mines. The mines 

are located 80 kilometers and 120 kilometers south of Nogales, Sonora. 

2.2.2.3 Other Means of Transport 

Nogales, Sonora has an international airport. The runway is 1800 meters long, 30 meters wide, and 

at an elevation of 1280 meters above sea level. 

2.3 Ports of Entry 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 22 

March 17, 2000 

Revised July 2005 
Mexico provides 75% of all vegetables consumed by Americans during the winter months of 

October through March. Nogales, Arizona is the largest port of entry for winter fruits and 

vegetables in the U.S. and Canada. Heavy trucks are common on Mariposa Road, I-19, and Route 

89. Thirteen trucking services are located in Nogales, Arizona. Up to 3,500 trucks per day pass 

northbound through a single highway port of entry. Two-thirds of all commercial traffic entering 

Arizona from Mexico passes through Nogales. 

U.S. Customs expedites the inspection of hazardous materials to enable them to leave the area 

quickly. In the event of a release from a truck, Customs would isolate the truck away from others. 

There are two ports of entry about 1 1⁄2 miles apart. Figure 2 shows the two ports. All trucks must 

use the western port (Mariposa). This port is open during normal business hours during the day. 

Cars may use the western port or the eastern (Nogales) port. This port is open 24 hours per day. If 

the western port were closed, all trucks would have to remain there until the port reopened. Cars 

would be diverted to the eastern port. If the eastern port were closed, all traffic (cars) would be 

diverted to the western port. Customs inspection of trucks occurs in an area near the border. 

In fiscal year 1998, over 4.7 million pedestrians, 3.5 million private vehicles, 256,000 commercial 

trucks, and 32,000 rail cars arrived in Nogales, Arizona from Mexico. 

Up to three rail crossings occur per day (morning, noon and evening) at the downtown port of entry 

(about 300 rail cars per day). In the U.S., the customs inspection of rail cars normally occurs in a 

rail yard with 4-5 tracks about half a mile north of the border. For 100% inspection of a train, U.S. 

Customs uses a rail yard in Rio Rico, about 8 miles north of the border. After inspection, the train 

proceeds to Tucson. In Mexico, the customs inspection of rail cars occurs outside of Nogales, 

Sonora. 

2.4 Sensitive Populations and Vulnerable Areas 

As a part of a hazard analysis, the identification of sensitive populations and vulnerable areas is 

necessary, especially drinking water supplies. This information is presented here. Figure 3 

highlights the water wells, rivers and water ways, major roads, and railroads in the two cities. 

Figure 4 highlights schools and hospitals. Figure 2 shows these features on a general map. 

2.4.1 Nogales, Arizona 

2.4.1.1 Sensitive Populations 

There are five public elementary schools, two middle schools, one public high school, two private 

elementary schools, and one private high school in Nogales, Arizona. School enrollment is more 

than 6,000 students. Health care facilities in Nogales, Arizona include the Carondelet Holy Cross 

Hospital, the Mariposa Community Health Center, and two outpatient treatment centers. The 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 23 

March 17, 2000 

Revised July 2005 
hospital has 80 beds. Medical practitioners include approximately 34 physicians, six dentists, three 

chiropractors, two podiatrists and five opticians. The schools and hospital are shown on Figures 2 

and 4. Numerous mobile home parks are located in Nogales, Arizona. Mobile home residents may 

be more vulnerable to environmental releases than those who live in fixed dwellings. 

2.4.1.2 Population Distribution 

Most of the industrial facilities are located in the western part of the city along Mariposa Road and I19. Most of the residential areas are located elsewhere, although some residential areas and schools 

are in the western part of the city, as shown on Figures 2 and 4. 

Transportation risks are the primary concern. Residential populations, businesses and schools are 

located along the major roads and railway, as shown on Figures 2 and 4. 

2.4.1.3 Sensitive Natural Resource Areas 

The Nogales, Arizona Water Department obtains water from water wells in the Santa Cruz River. 

The wells are located away from populated areas and major roads and railways. However, a release 

on the rail line in Mexico, where it runs near the river, could potentially affect the water wells of 

Nogales, Arizona within a few hours. The wells are equipped with a digital telemetry system that 

enables the Water Department to shut them down by computer within minutes. 

Nogales, Arizona supplies water to a few hotels and restaurants located in Nogales, Sonora through 

two water mains that cross the border. The water mains are equipped with backflow prevention. 

The water mains are shown on Figure 2. 

In areas not served by the Nogales, Arizona Water Department, residents and businesses obtain their 

water from private water companies, such as the Valle Verde Water Company. Valle Verde supplies 

water to areas near Grand Avenue and I-19. Their water wells are generally shallow and near the 

railway and the two main roads, I-19 and State Route 82. The proximity of the wells to the roads 

and railroads appears on Figures 2 and 3. A release on or near the road in these areas could 

contaminate these water wells. 

The Patagonia-Sonoita Creek Preserve is located 19 miles east of Nogales, Arizona on State 

Highway 82 near the Santa Cruz River. This wildlife preserve is owned and managed by the 

Arizona Chapter of the Nature Conservancy. It was purchased in 1966 with the help of the Tucson 

Audubon Society. It was the first project for the Nature Conservancy in Arizona, and now protects 

750 acres. In 1970, the preserve was recognized as a National Natural Landmark. The Nature 

Conservancy describes the preserve as “some of the richest of the remaining riparian (streamside) 

habitat in the region.” The preserve includes a perennial, spring-fed stream; a cottonwood-willow 

riparian forest; wetlands; rare and sensitive plant species; and over 260 bird species. The preserve 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 24 

March 17, 2000 

Revised July 2005 
is used by mammals, reptiles and amphibians. A release into the Santa Cruz River in Mexico could 

affect the preserve. 

2.4.2 Nogales, Sonora 

2.4.2.1 Sensitive Populations 

Nogales, Sonora offers schooling from pre-school to higher education. Basic education coverage is 

high and sufficient, but does not provide alternatives desired by the community, which causes 

students to move to other places in the country to continue their studies. The infrastructure for basic 

education includes 40 kindergartens, 57 elementary or grade schools, 13 secondary or middle 

schools, 2 secondary or middle interactive-schools, 5 centers for multiple special educations. More 

sensitive populations are in the subdivisions and settlements located around the washes and natural 

streams in the area. Schools in Nogales, Sonora are listed in Reference 8 and shown on Figures 2 

and 4. 

Public sector health providers serve children in first and second grade. ISSSTESON has two 

hospitals. IMSS, ISSSTE, and private clinics provide hospital services also. Although health 

services are close to 100 percent coverage, the quality is not yet up to the desired standards. There is 

a need to promote more investment for the improvement and expansion of medical facilities and 

acquisition of modern medical equipment. Medical facilities are shown on Figures 2 and 4. 

2.4.2.2 Population Distribution 

Some residential areas are located near the maquiladora facilities, as shown on Figures 2 and 4. As 

in Nogales, Arizona, transportation risks are the primary concern. Residential populations, 

businesses, schools, and medical facilities are located along the major roads and railway, as shown 

on Figures 2 and 4. 

2.4.2.3 Sensitive Natural Resource Areas 

Some of the water wells for Nogales, Sonora are located near the railway and Nogales-Hermosillo 

Highway. A release on the road or railway could affect those wells.

2.5 Drinking Water Supplies and Wastewater Treatment 

The Santa Cruz Basin aquifer is the primary source of water for Ambos Nogales. The aquifer is fed 

by the Santa Cruz River that originates in Arizona and travels south into Sonora, then west and north 

back into Arizona. For Nogales, Arizona, the water supply comes from well fields located in the 

Santa Cruz River east of the city and from wells located in Potrero Canyon west of the city. The 

Santa Cruz aquifer is narrow and shallow. It can come close to running dry if the region does not 

receive enough rain. The aquifer in Potrero Canyon is deeper and more substantial. It has not gone 

dry yet. In the past, Nogales, Arizona obtained drinking water from city wells in the downtown area. 

 The contaminant TCE has been found in those wells, which are now closed and capped. 

The Nogales, Arizona drinking water supply is stored in hilltop reservoirs on the west and east sides 

of the city. The city currently uses chlorine gas for water treatment, but is in transition to calcium 

hypochlorite tablets. 

In Nogales, Sonora, most of the city's water is drawn from shallow well fields to the east and 

southeast of the city and is augmented by a number of small wells in the city. Another important 

source of water is from wells located 21 kilometers south of the city, on the basin of Río Magdalena, 

brought to the city by an elevated, aboveground pipe. Because it is not underground, the pipe is 

subject to possible breakage. 

The Nogales Wash is a tributary to the Santa Cruz River. Several drinking water wells for both 

cities are located near the wash and the river. The Nogales Wash serves as a major drainage system 

for both cities. 

The Nogales International Wastewater Treatment Facility in the South Rio Rico Industrial Park 

treats wastewater from both cities. The sewer wastewater line that crosses from Nogales, Sonora 

into Nogales, Arizona is a 24-inch line that increases to 42 inches. The wastewater treatment facility 

discharges into the Santa Cruz River. 

2.6 Risk Reduction Opportunities and Recommendations 

Reducing risk to prevent a hazardous materials incident, natural disasters and WMD events is a 

proactive approach to emergency planning. The Binational Emergency Planning Committee (BEPC) 

will look at a variety of mechanisms to reduce hazardous materials risks in the plan area. These 

include: 

· Planning 

· Identification and assessment of public and private resources 

· Public and industry education and outreach 

· Procurement and integration of equipment 

· Building and fire codes 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 26 

March 17, 2000 

Revised July 2005 
 

· Pollution prevention 

· Traffic controls 

· Hazard identification and risk analysis 

· Training 

· Exercises and drills 

· Emergency response preparedness 

· Compliance assurance/assistance 

The overall resources of the two cities are very different. The city budget for Nogales, Arizona is 

about $36 million. The city budget for Nogales, Sonora is $6 million, even though the population is 

more than 10 times greater. 

In 2005, Nogales, Sonora, through the local unit of Civil Protection plans to allocate 20% coming 

from the collections made due to citations issued, to create a fund for the local emergency prevention 

and response. 

The Nogales, Arizona Fire Department has forty (40) certified hazardous materials technicians. The 

Fire Department believes that it needs a twenty (20) person hazardous materials team. 

The Binational Emergency Planning Committee, in the next two years, will seek support from other 

government agencies of both countries for the active participation in exercises and training of all 

those involved in this plan, to constantly improve the services rendered. 

The Binational Emergency Planning Committee must hold a meeting at least monthly to look for 

improved ways of reducing binational risks. 

The Nogales, Sonora Civil Protection staff are government employees. The Nogales, Sonora Fire 

Department staff is paid and volunteer. Most of the firefighters have other full-time jobs that they 

must leave when they need to respond to an emergency, they currently have sixteen (16) certified 

hazardous materials technicians. Nogales, Arizona has offered Incident Command System training 

to Nogales, Sonora firefighters, and is planning on providing WMD training. This training will 

include: Scene preservation, chemical ID, risk analysis, evidence collection, mass casualty decon, 

NIMS, radiation detection, secondary devices, detection of chemical and biological agents. At the 

conclusion of the training, participants will have a full understanding on how to deal not only with 

hazardous materials incidents, but WMD incidents as well. 

Nogales, Arizona hopes to be able to provide training and certification to 12-18 firefighters from 

Nogales, Sonora at the weapons of mass destruction technician level. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 27 

March 17, 2000 

Revised July 2005 
3.0 EMERGENCY RESPONSE OPERATIONS 

The adverse consequences of a WMD, natural disaster or chemical accident on the health, safety and 

welfare of the communities in Ambos Nogales may be reduced through timely and effective 

emergency response. This plan provides an integrated and coordinated joint binational response 

effort to supplement the local emergency response plans following the release of hazardous materials 

in the geographical area covered under this plan. Where portions of this section designate certain 

individuals to perform actions, this shall also include their designated representatives if appropriate. 

The Fire Departments of the two cities have long been assisting each other. The Nogales, Arizona 

Fire Department has sent advisors to assist the Nogales, Sonora Fire Department. Then, in 1999, the 

Nogales, Arizona Fire Department, for the first time, responded with a fire truck, hazardous 

materials unit and firefighters to assist the Nogales, Sonora Fire Department with a liquid butane 

release from a tank car. The tank car contained 1,000 kilograms of liquid butane. The smell of 

mercaptan from the release was strong. There was concern that the release may have entered the 

underground channel that flows from Nogales, Sonora to Nogales, Arizona. The Nogales, Arizona 

equipment and personnel crossed the border smoothly and quickly in both directions, and the release 

was stopped and cleaned up. 

3.1 Notification 

Any release or substantial threat of a release of a hazardous material, fire, natural disaster, or WMD 

event affecting or likely to affect another party shall be reported to that party without delay. The 

emergency notification list is on page 9. 

3.2 Private Response Mechanisms 

Owners or operators of fixed facilities and transportation facilities, including truck and rail lines and 

pipelines, must comply with all local, state, and federal hazardous material planning and reporting 

requirements. 

3.3 Local Response 

3.3.1 City of Nogales, Arizona Mutual Aid Request 

In Nogales, Arizona, the City of Nogales, Arizona Fire Department Fire Chief will assume the lead 

role as Incident Commander (IC). If the incident is beyond the control and/or capabilities of the 

Nogales, Arizona Fire Department, or the incident might impact the border with Mexico, the 

Incident Commander will request activation of the Emergency Operations Center (EOC). This 

request will initiate a binational notification response for mutual aid from Nogales, Sonora using a 

predetermined code to be shared only by the Ambos Nogales Fire Chiefs and the Director of Civil 

Protection. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 28 

March 17, 2000 

Revised July 2005 
 

 

Upon receipt of this request, the Nogales, Sonora Civil Protection and Fire Chiefs may implement 

the mutual aid request by providing necessary action, information and/or assistance resources if 

possible. The City of Nogales, Sonora may respond with the appropriate resources to aid in the 

request. These resources will be determined by a Joint Command established between the Nogales, 

Arizona and Nogales, Sonora Fire Chiefs and Civil Protection. The responding resources will report 

to the Incident Commander and work under the Incident Commander's direction. The Incident 

Commander is also responsible for ensuring that response personnel from Nogales, Sonora are 

adequately utilized in an effective and safe manner by coordinating with the senior on scene 

response official from each responding agency. 

If the incident is beyond the capabilities of both cities, the Fire Chief may contact the State of 

Arizona to request assistance and/or initiate federal and/or Joint Response Team response. 

3.3.2 City of Nogales, Sonora Mutual Aid Request 

In Nogales, Sonora, the Director of Civil Protection and/or the Nogales, Sonora Fire Chief will 

assume the lead role as Incident Commander (IC). If the Incident Commander feels that the incident 

will exhaust the resources available, or that the incident might impact the border, a request for 

binational response will be initiated to the Nogales, Arizona Fire Chief using the predetermined 

code. As with the Nogales, Arizona response, the binational response will involve requesting mutual 

aid from Nogales, Arizona. Both cities will notify their chains of command. 

Upon receipt of this request, the Nogales, Arizona Fire Chief will make a determination of 

appropriate actions and whether or not he is capable of responding without endangering his own 

responsibilities. The City of Nogales, Arizona may respond with the appropriate resources to aid in 

the request. These resources will be determined by a Joint Command established between the 

Nogales, Arizona Fire Chief, the Nogales, Sonora Fire Chief, and the Director of Civil Protection 

working under the following structure: Civil Protection will be administrative command. The 

Nogales, Arizona Fire Chief or the Nogales, Sonora Fire Chief (or their designated representatives) 

will be operations command. The responding resources will report to the Incident Commander and 

work under the Incident Commander's direction. 

Nogales, Arizona will also activate an Emergency Operations Center on the Nogales, Arizona side 

of the border. The Emergency Operations Center will evaluate the ongoing situation and assist the 

Incident Commander with resources and technical information. The Emergency Operations Center 

will also be responsible for ensuring that response personnel from Nogales, Arizona are adequately 

utilized in an effective and safe manner, by coordinating with the senior on scene response official 

from each responding agency. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 29 

March 17, 2000 

Revised July 2005 
If the incident is beyond the capabilities of both cities, the Director of Civil Protection, Sonora, may 

file a petition with Civil Protection, State of Sonora representative, to initiate a federal and/or Joint 

Response Team response. 

3.3.3 Local Response Duties 

Local agencies are responsible for emergency planning and preparedness within their jurisdictions. 

The agencies are expected to assume lead roles during the emergency phase of the incident. Local 

agencies will conduct response activities within the scope of their department training and 

capabilities. Local agencies will provide emergency response services when possible including, but 

not limited to: 

· Notification 

· Initial hazard identification 

· Initial sampling to identify and determine concentrations of materials, if possible 

· Communications 

· Rescue and emergency medical service 

· Fire fighting 

· Security (site perimeter, traffic, and crowd control) 

· On scene liaison with other agencies and organizations 

· Providing public information 

· Evacuation and shelter 

Local government assignments in Nogales, Arizona, are generally shared among various agencies. 

Detailed roles and responsibilities of these agencies can be found in the Nogales, Arizona and Santa 

Cruz County plans. Procedures for cross border emergency medical services are provided in 

Appendix D. 

When responding to requests for mutual aid, local response agencies from both sides of the border 

will adhere to their department’s standard operating procedures. At no time should personnel from 

either city be requested to perform duties outside their training and capabilities. Incident 

Commanders in both cities will become familiar with the capabilities of the agencies available for 

response and use the personnel from the agencies in an appropriate manner. If concerns arise, the 

Fire Chief and Civil Protection Joint Command will be notified and an appropriate decision will be 

made at that level. 

The City of Nogales, Arizona, Fire Department has Standard Operating Procedures for Hazardous 

Materials, as does the Nogales, Sonora Fire Department and Civil Protection, that detail response to 

contamination, flammable liquids and natural gas incidents and safe practices for atmospheric 

monitoring instruments. (Appendix E). 

3.4 State Response 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 30 

March 17, 2000 

Revised July 2005 
The State of Arizona can provide assistance for hazardous materials incidents to Nogales, Arizona 

and Nogales, Sonora, if the combined PRP and local capabilities or resources prove to be 

insufficient, incapable or inadequate. The Arizona Department of Environmental Quality will 

appoint a State On Scene Coordinator (SOSC) who will assist the Incident Commander by providing 

and overseeing needed state resources. 

Civil Protection for Nogales, Sonora, notifies Civil Protection, State of Sonora, when an incident 

occurs. If necessary, Civil Protection, State of Sonora, will respond with appropriate resources, and 

appoint a State On Scene Coordinator who will assist the Incident Commander by delivering and 

supervising state resources. 

3.5 Federal Response 

The U.S. EPA Regional Response Team and national level contingency planning through the 

National Response Team (NRT) perform regional level contingency planning. The Regional 

Response Team (RRT) is co-chaired by the U.S. EPA and the U.S. Coast Guard and consists of 

representatives from selected state and federal agencies. It plans, prepares and responds to 

hazardous materials incidents, providing advice and recommendations to the Federal On Scene 

Coordinator. 

In Mexico, Civil Protection has jurisdiction of hazardous materials incident planning. The National 

System of Civil Protection has established, in each federal and municipal entity, civil defense 

organizations to handle emergencies occurring in each jurisdiction. Civil Protection has prepared the 

"ANEXO III - Plan de Respuesta a Emergencia Con Materiales Peligrosos" (Annex III - Hazardous 

Materials Response Plan), and the Plan Nacional de Contingencias General (National General 

Contingency Plan). These plans are designed to be used by all entities in Mexico to aid in 

developing contingency plans for hazardous materials incidents in general. 

The Joint Response Team performs U.S.-Mexico border area contingency planning and training 

activities. The U.S. EPA co-chairs the Joint Response Team for the U.S. and PROFEPA co-chairs 

for Mexico. 

The U.S. federal government can provide assistance for hazardous materials incidents if combined 

local and state capabilities or resources prove insufficient, incapable or inadequate. Once the 

National Response Center (NRC) has been notified of a release, they alert the Federal On Scene 

Coordinator (FOSC), who may activate the Regional Response Team (RRT) or the National 

Response Team (NRT), depending on the severity of the incident. For incidents occurring in the 

Nogales, Arizona area, the Federal On Scene Coordinator will be from the U.S. EPA Region IX, 

headquartered in San Francisco, California. 

Normally, the U.S. EPA contributes to the response by working with the local, state, tribal and 

federal agencies and citizens to assure that the information needed to maximize the effectiveness of 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 31 

March 17, 2000 

Revised July 2005 
the response effort is easily accessible. If there is a spill where the potentially responsible party is 

not identified or does not contain, clean up the material, or adequately respond to the authorities, 

then federal responsibilities will prevail as outlined in the National Contingency Plan. These 

responsibilities include assisting state and local responders in the response or, in some 

circumstances, taking over the response. U.S. EPA also provides planning and preparedness 

assistance to prevent and mitigate environmental harm. 

The Mexico federal government can provide assistance through the National Civil Protection System 

for any hazardous materials incidents to Nogales, Sonora, if the combined potentially responsible 

parties and local capabilities or resources prove to be insufficient or inadequate. Civil Protection 

will appoint an On Scene Coordinator (OSC) who will assist the Incident Commander by providing, 

coordinating and overseeing needed federal resources. 

Federal agreements between the U.S. and Mexico require that each country notify the other of 

hazardous materials incidents if there is a release or substantial threat of release which may impact 

both sides of the border. The notification should occur between local authorities and between state 

authorities on both sides of the border to assure the information is properly elevated to the federal 

levels as required. 

3.6 Joint Response Team Responsibilities 

When the U.S. and Mexico have agreed to initiate a joint response to an incident, the function and 

responsibilities of the Joint Response Team include: 

· Advise the Federal On Scene Coordinator about measures needed to respond to the incident 

and what resources are available to carry out those measures; 

· Evaluate and make recommendations concerning the measures taken by the Federal On 

Scene Coordinator; 

· Provide continuing advice to the Federal On Scene Coordinator; 

· Coordinate and use as appropriate the resources that agencies or persons of the U.S. or 

Mexico or a third party can contribute; 

· Assist the Federal On Scene Coordinator in preparing information releases for the public; 

and 

· Participate in the termination of response. 

Binational Prevention and Emergency Response Plan

Revised July 2005 
 

4.0 INCIDENT RESPONSE OPERATIONS AND RESOURCES 

This plan employs the phases of operational response to an incident as outlined in the Joint 

Contingency Plan. 

4.1 Discovery and Notification 

Upon the discovery of a hazardous materials release, WMD event, fire, or a natural disaster, or 

threatened release within the city of Nogales, Arizona, a notification is made to the appropriate 

emergency organization. The initial notification will involve calling 911 to notify the Nogales, 

Arizona Fire Department. The agency receiving the initial contact will follow the Nogales, Arizona 

Fire Department's Standard Operating Procedure (SOP) for the notification of all other appropriate 

agencies. The potentially responsible party is also required to notify appropriate federal and state 

agencies by contacting the National Response Center and other state and local agencies depending 

on the substance released. In order to assure that other federal, state and local agencies have received 

the information, the National Response Center relays notifications that it receives to them. 

For Nogales, Sonora, the potentially responsible party is required to follow the normal reporting 

procedures for the City of Nogales, Sonora which includes calling 066, Civil Protection and the Fire 

Department. 

Binational agreements between the Governments of the United States and Mexico require that the 

countries notify each other in the event of a release or substantial threat of a release of a hazardous 

substance, pollutant, WMD event, fire, natural disaster, or contaminant affecting, or likely to affect 

the other country (Joint Contingency Plan Sections 105.3, 301). 

4.2 Preliminary Assessment and Initiation of Action 

The first official on the scene will assume the role of Incident Commander. This duty will be 

relinquished to the appropriate official upon that person’s arrival at the incident. All agencies report 

to the established Incident Commander for all response and recovery operations. Each agency will 

provide its own special equipment and reference data, and will function within its field of expertise. 

If an incident exceeds the resources of the local or county agencies, command may be transferred to 

the more appropriate responding agency. This function may also be transferred to the Federal OnScene Coordinator, if a federal or JRT response is activated. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 33 

March 17, 2000 

Revised July 2005 
4.2.1 Preliminary Assessment 

Upon confirmation that an incident may impact the other side of the border or may involve the 

release of hazardous materials, WMD event, fire, or a natural disaster, the Fire Department of 

Nogales, Arizona, the Fire Department of Nogales, Sonora or the Director of Civil Protection of 

Nogales, Sonora will assume the role of Incident Commander. The first official on the scene 

assumes the role of Incident Commander until the designated senior official arrives to coordinate the 

response. 

4.2.2 Initiation of Action 

Upon arrival on scene, the pre-designated Incident Commander will implement the following 

actions: 

·	 Relieve the first official on site; 

·	 Establish an Incident Command Post (ICP) and implement the Incident Command System

 (ICS); and 

· If the incident threatens the border or the cities of Nogales, Sonora or Nogales, Arizona, the 

Incident Commander will insure the appropriate notifications are made to the Joint Response 

Team, and if mutual aid will be required, insure that the proper notifications are made to 

implement a binational response. 

4.3 Containment 

The Incident Commander will implement appropriate measures to contain, restrict, reduce or 

eliminate the release or threat of release of hazardous materials, WMD event, fire, or a natural 

disaster at the incident, as well as downstream or downwind from the site. This includes defensive 

action to prevent, minimize, or mitigate an incident to protect public health and the environment. 

4.4 Documentation and Cost Recovery 

All actions taken during hazardous materials incidents will be carefully documented so that 

sufficient and accurate information is available to support the response and recovery operations, and 

to recover costs, if applicable. Documentation should be self-descriptive to prove the source and 

circumstances of the incident, identity of the potentially responsible parties, and impact or potential 

impact to public health and the environment. Documentation may be written, graphic, audiovisual, 

or in other form and will include the location of the incident, time, date and duration of the spill, 

source and cause of the incident, name and contact information of the potentially responsible parties, 

description of the released material, resources affected or threatened, status of response and cleanup 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 34 

March 17, 2000 

Revised July 2005 
efforts, and accurate accounting of public costs incurred. A notification form is provided for this 

purpose on page 10. 

Examples of other forms of documentation of hazardous materials incidents include: 

· Daily or personal logs in bound notebooks, to record all relevant response activities for 

evidentiary purposes; 

· Photographic documentation at the source of the release, pathway of discharge, and affected 

biota; 

· Samples of released material and material from the suspected source collected according to 

established chain of custody procedures; and/or 

· A statement of witnesses identifying the source of a release. 

4.5 Evacuation or Shelter-In-Place 

It is the responsibility of the Incident Commander to assess the hazardous materials release, WMD 

event, fire or natural disaster. If there is a threat to the public, immediate action needs to be taken 

for their protection. Actions which protect the public include first aid, search and rescue, 

designation of an exclusion zone, shelter-in-place, fire suppression and evacuation. 

If evacuation is necessary, the Incident Commander will determine the area that will require 

evacuation. The Incident Commander is also responsible for estimating the number of people in the 

evacuation area and number of people needing transportation assistance. The Incident Commander 

will follow all the appropriate Standard Operating Procedures (SOPs) outlined in the local plans. 

The Incident Commander will coordinate with law enforcement and the military to identify major 

evacuation routes and establish traffic control points. Law enforcement and/or the military will 

establish evacuation assembly points, monitor traffic flow on evacuation routes and establish 

security patrols and access control procedures. In a toxic environment, agencies with more 

appropriate protective clothing and equipment may be called upon to perform these tasks. 

If the incident is of sufficient magnitude that the potential for a cross border evacuation exists, the 

Incident Commander will work closely with the appropriate border agencies such as Customs and 

Border Protection authorities. 

4.6 Post-Incident Management 

The Incident Commander, or a designated replacement, is required to remain on scene until the 

immediate danger to public health and the environment has been abated. Primary responsibility for 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 35 

March 17, 2000 

Revised July 2005 
the actual cleanup and restoration costs will remain with the potentially responsible parties. In the 

event that the potentially responsible parties are unknown, cleanup is the responsibility of the parcel 

manager, the lessee, the land owner, the affected jurisdiction, the county agency, the state agency, or 

the federal agency having jurisdiction. 

Cleanup and disposal of the spill should be accomplished as soon as possible. Prompt action is 

important to minimize damage to the environment. The first step is to establish the cleanup 

priorities at the site. Once the priorities are set, determination of appropriate cleanup methods is 

necessary. The cleanup actions must be constantly monitored to ensure the cleanup priorities are 

being properly addressed. 

Evaluation of the cleanup to determine its effectiveness is necessary. The evaluation process should 

assess impacts on the habitat and organisms, effectiveness of removal, public concerns, aesthetics, 

and costs. The Incident Commander must develop criteria to determine when the cleanup is 

complete, using applicable or relevant and appropriate requirements. The Incident Commander will 

ensure proper transportation and disposal of hazardous substances in compliance with local, state 

and Federal laws. 

4.7 Response and Cleanup Funding Availability 

The Incident Commander will attempt to identify and have the party accountable for the release 

assume responsibility for containment, removal, and disposal. In Mexico, this will be responsibility 

of the PROFEPA authorities. 

If it is determined that the potentially responsible parties are not acting promptly, taking or 

proposing to take appropriate actions, or if the potentially responsible parties are unknown, state and 

federal funds may be made available to ensure proper cleanup. 

The State On Scene Coordinator or the Federal On Scene Coordinator may make funds available. 

Depending on the circumstances, money may be made available from one or more of the following 

funds. 

4.7.1 State Funds 

The State of Arizona and the State Water Quality Assurance Revolving Fund (WQARF) maintain 

funds that can be used for the response to hazardous materials incidents. These funds are available 

on a case-by-case basis, generally for incidents where a responsible party has not been identified or 

when there is an immediate threat to life and health. 

The Arizona Department of Environmental Quality (ADEQ) administers a fund to reimburse local 

government or political subdivisions for hazardous materials responses. 

Binational Prevention and Emergency Response Plan 

Nogales, Arizona/ Nogales, Sonora 36 

March 17, 2000 

Revised July 2005 
4.7.2 Federal Funds 

The U.S. EPA administers the Hazardous Substance Response Trust Fund (Section 2.1.1, 

“Comprehensive Environmental Response, Compensation and Liability Act”) and the Local 

Government Reimbursement Program. 

In Mexico, if the responsible party for the release is not located, a funding program is provided by 

PROFEPA to remedy abandoned areas containing hazardous wastes, or from the National Disaster 

Fund (Fondo Nacional de Desastres – FONDEN). 

4.8 Communications 

Communications will be established pursuant to the local municipal Standard Operating Procedures 

(SOPs). In the event of a binational response, communications must be effectively established as 

soon as possible. 

Due to the numerous radio frequencies used by the various response agencies in the Sister Cities 

area, the Incident Commander must define a primary response channel or rely on cellular 

communications. Communications between the Nogales, Sonora command and the Nogales, 

Arizona command must be established and maintained throughout a binational response. This will 

ensure a secure and reliable flow of information between the two commands. 

4.9 Health and Safety 

The Incident Commander will be responsible for appointing a Site Safety Officer (SSO) for the 

incident. The Incident Commander and Site Safety Officer will be responsible for developing and 

implementing a Site Safety Plan to ensure the health and safety of all response personnel. For 

response across the border, the Incident Commander and senior official of each response agency will 

ensure that the appropriate state and federal worker health and safety laws of their country are 

observed while in the neighboring country. 

4.10 Response Resources 

Figures 5 and 6 are emergency response organizational charts for Nogales, Arizona, and Nogales, 

Sonora, respectively. Appendixes F and G are lists of the emergency response resources for each 

city.

Revised July 2005 
5.0 TRAINING AND EXERCISES 

This plan, written pursuant to the U.S.-Mexico Joint Contingency Plan, is an administrative 

summary of the relevant hazardous materials emergency response plans which have jurisdiction 

within the planning area. Each of the operational plans referenced requires training and exercising 

to ensure that responders are always in a state of readiness. The concepts and resources for 

binational training and exercising are important to emphasize as binational relationships and 

activities develop. 

Preparing a written plan with well-defined operational roles, policies and resource acquisition 

procedures is an essential step. The written plan should contain training requirements and 

procedures for responders. Exercising the plan provides training, allows response personnel to 

become thoroughly familiar with response procedures, resources and systems, and enables planners 

to identify areas of the plan that need improvement. 

5.1 Training 

Individual organizations are responsible for their own training. Internal binational training, private 

contractors, and state or regional training resources are some of the binational options available to 

local agencies. Organizations must ensure that personnel are adequately trained for response 

operations they may perform. This training must comply with all applicable local, state, and federal 

worker health and safety regulations. 

5.2 Exercises 

Local, regional and binational hazardous materials contingency plan exercises are encouraged, as 

they are the best means of keeping the plans current and active. Nogales, Arizona and Nogales, 

Sonora routinely conduct joint exercises that allow for cross training of personnel. This ensures 

that deficiencies in response activities are identified. To keep this plan current, the plan will be 

exercised annually. Appendix J is a Revision Diary for future plan changes.
