Sector program

Chemical and HazMat

The Chemical Sector is an integral component of the U.S. economy, relying on and supporting a wide range of other critical infrastructure sectors.

The sector can be divided into five main segments, based on the end product produced:

• Basic chemicals

• Specialty chemicals

• Agricultural chemicals

• Pharmaceuticals

• Consumer products

Each of these segments has distinct characteristics, growth dynamics, markets, new developments, and issues.

The majority of Chemical Sector facilities are privately owned, requiring the Department of Homeland Security to work closely with the private sector and its industry associations to:

• Set goals and objectives

• Identify assets

• Assess risks

• Prioritize needs

• Implement protective programs

The Department of Homeland Security builds stakeholder capacity and enhances critical infrastructure security and resilience through voluntary partnerships that provide training, resources, and exercises. The Department has also issued regulatory Chemical Facility Anti-Terrorism Standards (CFATS) for any facility that manufactures, uses, stores, or distributes certain chemicals at or above specified quantities or concentrations.

Communications

The Communications Sector is an integral component of the U.S. economy, underlying the operations of all businesses, public safety organizations, and government. Presidential Policy Directive 21 identifies the Communications Sector as critical because it provides an “enabling function” across all critical infrastructure sectors. Over the last 25 years, the sector has evolved from predominantly a provider of voice services into a diverse, competitive, and interconnected industry using terrestrial, satellite, and wireless transmission systems. The transmission of these services has become interconnected; satellite, wireless, and wireline providers depend on each other to carry and terminate their traffic and companies routinely share facilities and technology to ensure interoperability.

The private sector, as owners and operators of the majority of communications infrastructure, is the primary entity responsible for protecting sector infrastructure and assets. Working with the federal government, the private sector is able to predict, anticipate, and respond to sector outages and understand how they might affect the ability of the national leadership to communicate during times of crisis, impact the operations of other sectors, and affect response and recovery efforts.

The Communications Sector is closely linked to other sectors, including:

• The Energy Sector provides power to run cellular towers, central offices, and other critical communications facilities;

• The Information Technology Sector provides critical control systems and services, physical architecture and Internet infrastructure;

• The Financial Services Sector relies on communications for the transmission of transactions and operations of financial markets; and

• The Emergency Services Sector depends on communications for directing resources, coordinating response, alerting the public, and receiving emergency 911 calls.

Dams

The Dams Sector delivers critical water retention and control services in the United States, including hydroelectric power generation, municipal and industrial water supplies, agricultural irrigation, sediment and flood control, river navigation for inland bulk shipping, industrial waste management, and recreation. Its key services support multiple critical infrastructure sectors and industries. Dams Sector assets irrigate at least 10 percent of U.S. cropland, help protect more than 43 percent of the U.S. population from flooding, and generate about 60 percent of electricity in the Pacific Northwest.

Emergency Services

A system of prevention, preparedness, response, and recovery elements, the Emergency Services Sector (ESS) represents the nation's first line of defense in the prevention and mitigation of risk from both intentional and unintentional man made incidents, as well as from natural disasters. The ESS also serves as the primary protector for the other 15 critical infrastructure sectors.

Encompassing a wide range of emergency response functions, the primary mission of the ESS is to:

• Save lives

• Protect property and the environment

• Assist communities impacted by disasters

• Aid in recovery from emergencies

These functions, the majority of which are performed at the state, local, tribal, and territorial levels, are defined by five disciplines:

• Law Enforcement

• Fire and Emergency Services

• Emergency Management

• Emergency Medical Services

• Public Works

Additionally, there are several specialized capabilities identified within the ESS, such as:

• Hazardous Materials

• Search and Rescue

• Hazardous Devices Team/Public Safety Bomb Disposal

• Tactical Teams (i.e., SWAT)

• Aviation Units (i.e., police and medevac helicopters)

• Public Safety Answering Points (i.e., 9-1-1 call centers)

Financial Services

The Financial Services Sector represents a vital component of our nation's critical infrastructure. Large-scale power outages, recent natural disasters, and an increase in the number and sophistication of cyber attacks demonstrate the wide range of potential risks facing the sector.

Financial institutions provide a broad array of products from the largest institutions with assets greater than one trillion dollars to the smallest community banks and credit unions. Whether an individual savings account, financial derivatives, credit extended to a large organization, or investments made to a foreign country, these products allow customers to:

1. Deposit funds and make payments to other parties;

2. Provide credit and liquidity to customers;

3. Invest funds for both long and short periods; and

4. Transfer financial risks between customers.

Financial institutions are organized and regulated based on services provided by institutions. Within the sector, there are more than 18,800 federally insured depository institutions; thousands of providers of various investment products, including roughly 18,440 broker-dealer, investment adviser, and investment company complexes; providers of risk transfer products, including 7,948 domestic U.S. insurers; and many thousands of other credit and financing organizations.

Government Facilities

The Government Facilities Sector includes a wide variety of buildings, located in the United States and overseas, that are owned or leased by federal, state, local, and tribal governments. Many government facilities are open to the public for business activities, commercial transactions, or recreational activities while others that are not open to the public contain highly sensitive information, materials, processes, and equipment. These facilities include general-use office buildings and special-use military installations, embassies, courthouses, national laboratories, and structures that may house critical equipment, systems, networks, and functions. In addition to physical structures, the sector includes cyber elements that contribute to the protection of sector assets (e.g., access control systems and closed-circuit television systems) as well as individuals who perform essential functions or possess tactical, operational, or strategic knowledge.

The Education Facilities Subsector covers pre-kindergarten through 12th grade schools, institutions of higher education, and business and trade schools. The subsector includes facilities that are owned by both government and private sector entities.

The National Monuments and Icons Subsector encompasses a diverse array of assets, networks, systems, and functions located throughout the United States. Many National Monuments and Icons assets are listed in either the National Register of Historic Places or the List of National Historic Landmarks.

Information Technology

The Information Technology Sector is central to the nation’s security, economy, and public health and safety. Businesses, governments, academia, and private citizens are increasingly dependent upon Information Technology Sector functions. These virtual and distributed functions produce and provide hardware, software, and information technology systems and services, and - in collaboration with the Communications Sector - the Internet. The sector’s complex and dynamic environment makes identifying threats and assessing vulnerabilities difficult and requires that these tasks be addressed in a collaborative and creative fashion.

Information Technology Sector functions are operated by a combination of entities - often owners and operators and their respective associations - that maintain and reconstitute the network, including the Internet. Although information technology infrastructure has a certain level of inherent resilience, its interdependent and interconnected structure presents challenges as well as opportunities for coordinating public and private sector preparedness and protection activities.

Transportation

The Department of Homeland Security and the Department of Transportation are designated as the Co-Sector-Specific Agencies for the Transportation Systems Sector. The nation's transportation system quickly, safely, and securely moves people and goods through the country and overseas.

The Transportation Systems Sector consists of seven key subsectors, or modes:

• Aviation includes aircraft, air traffic control systems, and approximately 450 commercial airports and 19,000 additional airports, heliports, and landing strips. This mode includes civil and joint use military airports, heliports, short takeoff and landing ports, and seaplane bases

• Highway Infrastructure and Motor Carrier encompasses nearly 4 million miles of roadway, almost 600,000 bridges, and some 400 tunnels in 35 states. Vehicles include automobiles, motorcycles, trucks carrying hazardous materials, other commercial freight vehicles, motorcoaches, and school buses

• Maritime Transportation System consists of about 95,000 miles of coastline, 361 ports, 25,000 miles of waterways, 3.4 million square miles of Exclusive Economic Zone, and intermodal landside connections, which allow the various modes of transportation to move people and goods to, from, and on the water

• Mass Transit and Passenger Rail includes service by buses, rail transit (commuter rail, heavy rail--also known as subways or metros--and light rail, including trolleys and streetcars), long-distance rail--namely Amtrak and Alaska Railroad--and other, less common types of service (cable cars, inclined planes, funiculars, and automated guideway systems)

• Pipeline Systems consist of vast networks of pipeline that traverse hundreds of thousands of miles throughout the country, carrying nearly all of the nation's natural gas and about 65 percent of hazardous liquids, as well as various chemicals. These include approximately 2.2 million miles of natural gas distribution pipelines, about 168,900 miles of hazardous liquid pipelines, and more than 109 liquefied natural gas processing and storage facilities

• Freight Rail consists of seven major carriers, hundreds of smaller railroads, over 140,000 miles of active railroad, over 1.3 million freight cars, and roughly 20,000 locomotives. Further, over 12,000 trains operate daily. The Department of Defense has designated 30,000 miles of track and structure as critical to mobilization and resupply of U.S. forces.

• Postal and Shipping moves over 574 million messages, products, and financial transactions each day. Postal and shipping activity is differentiated from general cargo operations by its focus on letter or flat mail, publications, or small- and medium-size packages and by service from millions of senders to nearly 152 million destinations.
