Introduction TECO Peoples Gas’ family of companies began distributing manufactured gas products in Florida in 1865. Approximately one hundred years later, modern natural gas pipelines replaced these manufactured gas plants with a sophisticated network of interstate and intrastate pipelines. Today Peoples Gas serves over 340,000 customers, including residential, commercial and industrial, through a network of more than 11,000 miles of gas main. This represents approximately one-half of the natural gas customers in the state of Florida.

Pipeline Purpose and Reliability From natural gas wells in the Gulf of Mexico, gas is gathered through a system of interstate pipelines running from Texas, Louisiana, Mississippi, Alabama and Florida. One pipeline crosses the Gulf of Mexico from Mobile Bay to Tampa Bay, providing an alternate supply to Florida residents. Peoples Gas accepts delivery of this gas supply and distributes it to a diverse group of customers within the state, providing an efficient, reliable and domestically-produced energy source.

Safety and Security The natural gas industry invests time and money in its pipeline system to ensure safety and reliability. Natural gas pipelines have an outstanding safety record, especially when compared to other modes of transportation. According to National Transportation Safety Board Council 2009 statistics, 33,808 transportation fatalities occurred on the highways, while aviation, boating and railroads accounted for another 2,106 fatalities. In contrast, the number of fatalities associated with natural gas pipelines was 14.

2010-2011 Edition 9

A copy of our Material Safety Data Sheet is included in Appendix A for your reference. Also, Appendix C contains a typical emergency response plan for natural gas emergencies. In the event of a gas emergency the company may seek to establish flow control measures. Flow control, pressure reduction or pipeline shutdown may take place remotely from the incident scene. Occasionally, pipeline shutdown is facilitated at the incident scene using a pipeline squeeze-off tool. The application of flow control is dependent on system design. It is not always possible or feasible to stop the flow of escaping gas. Each incident is unique and must be evaluated. Because natural gas is very compressible, even when a pipeline is shut down, it may take a long time before all the gas has escaped and the incident is safe.

Natural Gas Operations Only Peoples Gas delivers only natural gas to its customers. It is no longer in the propane market and does not operate any propane facilities or delivery services. As such, Peoples Gas personnel are not trained in emergency propane response, and the company does not have emergency response equipment suitable to mitigate propane emergencies.

TECO Peoples Gas Safety Policy for Employees Responding to Natural Gas Emergencies At TECO Energy, safety is our first core value. We emphasize a safe work environment and a culture of looking out for the safety and well-being of each other, our customers and our community. We believe the safety of life outweighs all other considerations. No employee (or company contractor) is permitted to enter an engulfing flammable atmosphere unless these conditions have been met:

1.) All tactical strategies to effect repair, including pressure reduction and flow control, have been taken first;

2.) Donning complete thermal protection (company bunker gear) and SCBA;

3.) Supporting attendants are available to monitor site conditions, man lifelines (if needed), and fire extinguishers;

4.) Entrants have free access and egress from the exclusion zone.

Public Awareness Programs TECO Peoples Gas operates a continuing education program to make the public, excavators, and governmental organizations aware of the possible hazards associated with the unintended release of natural gas. Each interest group is targeted with a special outreach program. These outreach programs are conducted using bi-lingual promotional materials to reach the widest demographic audience.

Educating the Public Newspaper advertisement reaches a wide public audience. In 2011 over 2 million Florida residences received this important message from TECO Peoples Gas through 19 different newspapers.

Educating Excavators The majority of pipeline leaks statewide are the result of excavation damages. These damages have the potential for serious consequences within the neighborhoods where they occur. Most often, these types of excavation damages are preventable. This equates to approximately 1,600-1,700 excavation damages each year. TECO Peoples Gas targets professional excavators with educational materials in a unique outreach using direct mailers. More than 46,000 bi-lingual safety brochures were sent during calendar year 2011 to educate excavators. State Law, § 556, requires excavators to notify Sunshine State One-Call of Florida, the state utility notification

2010-2011 Edition 11

center, two full business days prior to excavating. This advanced warning allows underground facility owners like TECO Peoples Gas an opportunity to visit the job site and mark the estimated horizontal route of any pipelines at the dig site. Last year Peoples Gas received approximately 268,000 requests to mark facilities from Sunshine State One-Call of Florida. TECO Peoples Gas is a founding member of Sunshine State One-Call.

Sunshine State One-Call has a comprehensive outreach program creating awareness of the hazards of excavation for all underground facility owners. On line excavator training programs are available to assist any damage prevention stakeholder in the basic requirements of state law and industry best practices. This award- winning program distinguishes Sunshine’s public awareness programs among other states. Likewise, Sunshine holds many forums and seminars around the state each year as well as private training workshops all focusing on damage prevention. In accordance with recently enacted federal regulations (FCC), Sunshine State One-Call has begun operating the new national 3-digit toll free access number - 811 - within the state of Florida. Excavators can connect to the utility notification center and provide excavation information by dialing the toll free number. There has been some concern that the 811 dialing code is too close to the emergency number, 911. However, there is little that can be done to eliminate miss-dialing. Moreover, since this is a national effort mandated by the federal government there is little that can be done to change it.

Additional Public Awareness Information Additional safety information can be obtained by accessing the TECO Peoples Gas website at peoplesgas.com/safety.

2010-2011 Edition 13

Integrity Management Programs at TECO Peoples Gas In accordance with recently enacted federal regulations, some segments of our transmission pipelines have been designated as High Consequence Areas (HCAs). An HCA generally means that transmission pipelines traverse neighborhoods that have buildings which house 20 or more people. These pipeline facilities have undergone a supplemental hazard assessment and prevention program called Integrity Management Programs. To learn more about the location of gas transmission facilities and other pipelines, Emergency Officials are encouraged to visit the National Pipeline Mapping System at npms.phmsa.dot.gov, where TECO Peoples Gas has placed facility records showing their location. Building and zoning officials should consider land use practices along the routes of these transmission corridors. If they have safety concerns, they should contact the local operating center nearest the transmission corridor for additional information.

2012-2013 Edition 14

Pipeline Marker Information

TECO Peoples Gas uses pipeline markers to designate underground corridors of all transmission pipelines and certain distribution pipelines. These pipeline markers are not intended to represent the exact location of the underground facility, but are placed to alert the public, especially excavators, to the presence of a pipeline facility. Pipeline markers are frequently placed in areas of new construction, where excavation activities are likely to follow. Moreover, pipeline markers serve to protect the facility while permanent records are being updated, and pipeline protection teams are educated about their presence. Excavators working in the area of a pipeline marker will quickly identify the pipelines and take precautionary measures. Marker posts provide an on-site warning to everyone, and therefore are a key element in the company’s damage prevention program.

2010-2011 Edition 25

Appendix C Control of Natural Gas in Emergencies Factual Information About Natural Gas 1. Natural gas is neither toxic nor poisonous. Tests show that concentrations of 25 percent natural gas mixed with air produce no ill effects. However, if natural gas displaces the air in an enclosed space, suffocation can occur because of the lack of oxygen. 2. Natural gas is lighter than air, and it will rise and diffuse rapidly when it escapes in an open area. When confined in a closed room, the gas will rise to ceiling level. The air in the room will be displaced from the top downward. Remember this when you ventilate a room. Open windows from the top and bottom. Lighter-than-air natural gas should not be confused with liquefied petroleum gas. This gas is more commonly called L.P., bottle gas, propane, butane, and various other trade names. Liquefied petroleum gases are all heavier than air and collect in low places when not confined. 3. Most natural gas is odorless in its natural state; therefore, an odorant is usually added to give it a distinctive odor of rotten eggs. 4. Burning natural gas produces a high radiant heat. Combustibles must be wetted down to prevent their ignition by this radiated heat. 5. The ignition point of natural gas is 1,100 – 1,200 degrees Fahrenheit. This temperature is reached by pilot lights, flint sparks, matches, or sparks from electrical switches or motors. Procedures During Emergencies The gas company employee, the firefighter, and other emergency personnel have the same goals when they are brought together in an emergency situation involving natural gas. Firefighters, by supplementing their overall knowledge of emergency measures with helpful information provided by gas company employees, can more effectively protect the public they serve. The main purpose of this booklet is to provide emergency personnel with general information about emergency procedures involving natural gas. It also includes several examples of specific information provided by the gas company employee "at the scene" that can be beneficial in controlling an emergency. These emergencies will involve one or more of five basic situations:

2012-2013 Edition 26

1) Gas Escaping Outside 2) Gas Burning Outside 3) Gas Escaping Inside 4) Gas Burning Inside 5) Function of Relief Valves

Upon the first indication that gas is involved, CALL THE GAS COMPANY at 1-

877-TECO-911. This may be immediately after the call is received at the fire station or when the firefighter arrives at the scene, but whenever and wherever natural gas is involved, immediately call the gas company. Gas company personnel are instructed to report their presence upon arrival to the fire officer in charge. 1. Gas Escaping Outside If natural gas is escaping from the ground, an excavation, an open pipe, a manhole, a sewer or a vault, clear a safe area around the location and barricade or rope it off. If possible, police and firefighters should check with the gas company employee before advising the public in the immediate vicinity of the emergency what measures, if any, should be taken. The special knowledge of the gas company employee may help avoid causing undue alarm and unnecessary action by the public in adjacent or removed locations. In most instances the gas company employee will cut off the gas to adjoining properties and advise the customers of safety precautions to be taken, such as extinguishing all open flames, prohibiting smoking and making certain that electrical switches or similar possible ignition sources are not operated. Gas company employees will also check for gas in surrounding buildings, particularly in basements. It may be necessary to restrict or reroute all traffic until the gas flow is brought under control. Manholes or vaults can usually be vented by temporarily removing their covers. 2. Gas Burning Outside If natural gas is burning outside, the firefighter should make no attempt to extinguish the fire. Burning gas will not explode, but it may ignite surrounding combustibles. Clear the danger area and barricade or rope it off. DO NOT OPERATE GAS VALVES IN THE STREET - HAVE THE GAS COMPANY EMPLOYEE DO IT. Turning the wrong valve could create another emergency.

2010-2011 Edition 27

Gas company employees, with their special knowledge and information, can avoid this. Spray water mist on any surrounding combustibles if they are in danger of igniting. Do not use water on burning natural gas at its point of escape. If this point is in an excavation, the hole will be filled with mud, making the repair slower and more hazardous. 3. Gas Escaping Inside If natural gas is escaping inside a building, ventilate the area starting where the gas concentration is strongest. If gas is escaping in quantity, clear the building of its occupants. Shut off open flame devices by operating manual controls, but do not operate electrical switches. The fire officer in charge may determine that it is necessary to shut off the gas to the building at the service valve. The necessity of this action should be weighed against the fact that turning off the gas in commercial or industrial areas might seriously interrupt important production processes and possibly create further hazards. Again, your gas company employee can give you specific information to help evaluate the situation. If a firefighter or other emergency personnel turns off a valve, leave it off, then immediately tell the gas company employee. After a valve has been shut off, only gas company employees should turn it on again, because they have the experience and training necessary to evaluate the conditions and determine when this action is advisable. 4. Gas Burning Inside If natural gas is burning inside a building, shut off the gas at the meter, or, when available, at an outside valve. If the gas supply cannot be safely shut off, keep the surrounding combustibles wetted with spray stream until the gas company emergency crews can control the flowing gas. If it appears that inside piping or meter installations are going to be endangered by a non-gas fire in a building, the fire officer in charge can determine if it is necessary to turn off the gas. Again, the gas company employee can help evaluate the situation. If a fire is caused by a gas appliance that is burning out of control, it is usually enough to shut off the gas at the appliance's valve. When this is not practical, or the valve cannot be located, shut off the gas at the meter supplying the appliance. 5. Function of Relief Valves in Distribution Systems A relief valve protects gas systems from accidental over-pressuring. Gas company control points with relief valves are sometimes referred to as district regulating

stations, city gate stations or town border stations. Each pressure reducing regulating station has a gas regulator set to maintain a fixed down-stream pressure. If for any reason there is a malfunction and the regulator fails to properly limit downstream pressure, the relief valve will open to protect the system. When this occurs, gas is vented into the atmosphere, usually accompanied by a loud, high-pitched noise. Natural gas, which is much lighter than air, diffuses upward into the atmosphere. A RELIEF VALVE VENTING GAS INTO THE ATMOSPHERE IS PERFORMING ITS PROPER FUNCTION. IT SHOULD NEVER BE CUT OFF OR RESTRICTED UNTIL A GAS COMPANY EMPLOYEE ARRIVES AND MAKES CORRECTIONS. Anyone who sees or hears a relief valve venting gas to the atmosphere should call the gas company at once, but take no action which would keep the relief valve from venting gas into the atmosphere.

Example 1 shows a typical relief valve installation. The relief valve may be recognized as one connected to a discharge pipe extending upward, usually with a rain cap on the end. Most companies install a standard cutoff valve below the relief valve with a lock to keep it in an open position. The lock is to keep unauthorized persons from closing the valve and rendering the relief valve ineffective.

Example 2 is a typical meter facility on a utilization pressure system which has operating pressures in the piping on both sides of the meter at about one-quarter pound per square inch. This application is sometimes used for commercial buildings, regulator stations and city gate stations.

The typical cutoff valve can be operated (open or closed) by turning it one-quarter turn, 90 degrees. Example 2 is a typical meter facility on a low or utilization pressure system. Note: There is no regulator upstream of the meter.

Example 3 is a typical meter facility on a medium pressure system. This installation differs from Example 2 in that a regulator is included to reduce the pressure of the incoming gas from pounds per square inch to utilization pressure of about one-quarter pound per square inch.

Example 4 shows meter facilities for multiple-dwelling buildings. There is a master control valve which shuts off the gas to all the meters in the manifold, and there is also a valve on the inlet side of each individual meter. This makes it possible to shut off gas to an apartment where an emergency situation exists without interrupting service to units in other parts of the building. The number of the apartment served appears on the front of or on a tag attached to the particular meter.

The meter facilities shown in Example 5a and 5b are used for large industrial and commercial gas users and are located outside the building, inside the building, or in their own separate buildings.

Gas Detection Odors sometimes mistaken for natural gas can come from many sources such as petroleum products (especially gasoline), marsh gas, sewer gas, industrial gases and even some batteries being charged are typical examples. There are many types of gas detection instruments, and since the gas company employee is trained in their use, he will be glad to assist you. Natural gas has its odor regulated by the gas company in order to give it a sufficiently distinctive and recognizable odor. It is suggested that emergency personnel familiarize themselves with the odor of the gas distributed in their area. Press Relations and Publicity In an emergency involving natural gas, refer inquiries from press representatives and other interested parties to a gas company representative if available. The gas company representative will be able to clarify technicalities and provide other information necessary for complete and accurate reporting of the emergency. Proper identification of the type of "gas" is of vital importance. If the emergency involves natural gas, be sure to identify it as "natural gas." If gasoline, chlorine gas, sewer gas, propane, etc., is involved, always carefully identify the type. The gas company's objective in working with press, TV, and radio representatives during an emergency is the same as that of emergency personnel - to be helpful and cooperative in determining the cause of an emergency and to accurately report the cause to the public.
