Emergency Management Program ___ __________________________ 1.4. System DescriptionThe following is a description of the Centra Pipeline system (assets) and the governmental regions inwhich the system is located. The government agencies in these regions have primary responsibilities foremergencies occurring within their jurisdiction. All of these agencies have received informationregarding the Centra Pipeline assets present in their communities. The locations of Centra assets areshown on the Emergency Response Maps in Annex 3 of the EMP and Emergency Response Areas areidentified below in Section 1.5.The facilities owned and operated by Centra Pipeline originate at Station 43 of the TransCanada PipelineSystem (T.C.P.L.), which is 15 km. (9 m) east of Richer Manitoba, on Trans-Canada Highway #1. Thecustody transfer point between Centra and T.C.P.L is at the east fence line on T.C.P.L’S property.The gas is metered by T.C.P.L. and is carried in Centra’s pipeline into the Spruce Siding Check MeterStation. This site contains additional metering and pressure regulation equipment and is the locationwhere odorant is injected into the system. The Spruce Siding Station is located in the RegionalMunicipality of Reynolds (RM of Reynolds), Manitoba.The 12” pipeline leaves Spruce Siding Station and heads southward through the St. Labre and BadgerBlock Valves and has a maximum allowable operating pressure of 802 psig. The pipeline then turnssouth, south east to the Sprague Compressor Station consisting of a 1300 hp Solar Saturn Compressor,controlled by Union Gas - Gas Control. All of the above assets are owned and operated by Centra. Theyare located in the Regional Municipality of Piney (RM of Piney), Manitoba. There is one tap off themainline near Vassar, Manitoba serving an industrial customer in that area. The station serving thisindustrial customer is owned and operated by Manitoba Hydro.After leaving Sprague, the pipeline enters the United States, about 3 km (2 miles) downstream of theSprague Compressor Station. The pipeline serves the communities of Roseau, Lakewood, Warroad, andBaudette through Town Border Stations owned and operated by Centra. The distribution systems areowned and operated by Minnesota Energy Resources Company (MERC). There are block valves locatedat Warroad, Williams, the Roseau lateral tap, and one just over 1 mile northeast of the Roseau TBS. Thepipeline re-enters Canada about 1.6 km (1 mile) east of the Baudette TBS. At this point the 12” pipelinesplits and both pipes cross the Rainy River and re-connect on the Canadian side of the river withisolation valves located on both sides of the river.The single 12” pipe travels east for approximately 3 km (2 miles) to the Rainy River Block Valve and RainyRiver TBS. The pipeline then continues east for approximately 5 miles to the Rainy River CompressorStation. The Rainy River Block Valve and Compressor Station are located in Dawson Township. Thiscompressor station also consists of a 1300 hp Solar Saturn Compressor, controlled by Union Gas - GasControl. Date: Manual Title: Page:25 May 2017 Emergency Management Program 7/47

Emergency Management Program ___ __________________________From the compressor station the pipeline continues east through the following municipalities:  Dawson Township (includes the Pinewood TBS);  Morley Township (includes the Marr Road Block Valve and Stratton TBS);  Chapple Township (includes the Barwick TBS);  Rainy River First Nations (includes the Manitou Rapids TBS);  Emo Township (Emo Block Valve and Emo TBS);  Lavallee Township (includes Devlin TBS);  Alberton Township;  Town of Fort FrancesThe pipeline enters the Fort Frances Primary Station where gas flow is metered and the pressure isreduced to 385 psig. In the Fort Frances area, the pipeline serves the McIrvine Rd and Mowat TownBorder Stations; the Fort Frances paper mill; and the Church Street District Regulator Station where thepressure is reduced to 200 psig. The 12” 200 psig line then crosses the Boise Bridge to serve theInternational Falls TBS and the International Falls paper mill. 1.5. Emergency Response AreasFor the purposes of this Program the pipeline has been divided up into three sections…Minnesota,Manitoba, and Ontario. Within each section there are Emergency Response Areas that have beenidentified as shown on the following maps. Each emergency response area is served by separateemergency response agencies. In the event of an incident on Centra’s system it is likely that emergencyresponders from several agencies would be responding through mutual aid agreementsOntario Emergency Response Areas Primary Contact Number 911Dawson 911Morley 911Chapple 911Emo 911LaVallee 911Alberton 911Fort Frances 911Manitou Rapids 1st Nation 911Manitoba Emergency Response Areas 911Reynolds 911Piney 911Minnesota Emergency Response Areas Page: 8/47Roseau Manual Title:Warroad Emergency Management Program Date: 25 May 2017

Emergency Management Program ___ __________________________2. Incident Management SystemThis section of the Program is intended to provide detailed emergency response instructions andexpectations. Because emergency response agencies along Centra’s system utilize some form of theIncident Command System (ICS) for emergency response, Centra’s incident management will also beguided by the principles of ICS. Centra will work with emergency response agencies and otherstakeholders to provide a coordinated response to protect public safety, property and the environment.While this section provides detailed instructions, these procedures cannot consider every possibleemergency. These procedures are provided to form a foundation that can easily be expanded to manyother emergencies, if personnel are familiar with these procedures and apply good judgment andcommon sense. 2.1. Emergencies - Hazard Identification and AssessmentAn emergency is a present or imminent event that requires prompt coordination of actions or specialregulation of persons or property to protect the health, safety or welfare of people or to limit damage toproperty or the environment. There are many different events that can create emergencies involvingCentra transmission facilities. Those events could be the result of: 1. Human Activities – excavation, transportation accidents, vandalism, terrorism, etc. 2. Acts of Nature – tornadoes, floods, wild fires, severe summer or winter storms, etc. 3. Equipment / Material failure – pipe defects, pressure regulating equipment, improper installation or operation, etc.Hazard identification and risk assessment for Emergency Management are conducted in accordancewith the Risk Management and Risk Assessment Procedures. Risk Assessments also identify the controlsused to mitigate the identified hazard/risks. Results of the latest risk assessment can be found inQuickBase under the Risk Management app. Date: Manual Title: Page:25 May 2017 Emergency Management Program 14/47

Emergency Management Program ___ __________________________ Date: Manual Title: Page:25 May 2017 Emergency Management Program 15/47

Emergency Management Program ___ __________________________ 2.2. Emergency Level DefinitionsAny potential emergency requires an immediate response and shall be classified using the following EmergencyLevel Definitions. The Emergency Level must be communicated to Gas Control and all other personnel involvedwith the emergency response including emergency response agencies.Level 1 emergencyA Level 1 emergency shall be declared when the emergency is contained within the boundaries of a facility, andcan be totally controlled by company personnel without external responder support. No immediate threat to thepublic, company personnel or the environment.Level 2 emergencyA level 2 emergency shall be declared when there is no immediate threat outside company property but thepotential exists to extend beyond property boundaries and may become a threat to the public, company personnelor the environment. Outside services and government agencies are likely to be directly involved.Level 3 emergencyA Level 3 emergency shall be declared when there is an immediate threat to life, property, or the environment.External responder support is required to assist company personnel to totally control the emergency. A Level 3emergency could also involve volume curtailment and/or Force Majeure situations.If conditions change during an emergency to the extent that the emergency meets the criteria of a differentemergency level, the level must be either upgraded or downgraded depending on the criteria that is met. Thechange in emergency level must be communicated to all personnel involved with the emergency responseincluding emergency response agencies. The termination of an emergency will occur whenever the conditionsnoted in section 2.1 no longer exist. 2.3. Discovery Scenarios and Initial ResponseDiscovery of a potential emergency involving the hazards identified above will likely result from one of thefollowing sources: 1. Gas Control will observe or a third party may report an abnormal operating condition such as an unusual increase or decrease in pressure or flow which could be an indication of a potential emergency condition.Initial Response:The Gas Control group shall be responsible to manage the system operation by conferring with Centra personneland assisting with both manual and remote adjustments to minimize hazards to life and property and aspracticable meet the system throughput capacity requirements resulting from the emergency. Gas Controlpersonnel will be responsible for the effective management of these obligations and will arrange for assistancefrom the Gas Control Emergency Team as required.Gas Control shall take actions to identify, confirm the emergency by: Date: Manual Title: Page:25 May 2017 Emergency Management Program 16/47

Emergency Management Program ___ __________________________  Evaluating the validity and impact of the emergency as it pertains to system throughput capacity  Contacting operations / standby personnel and make them aware of the problem.  Managing the system operation by assisting Centra with both manual and remote adjustments to primarily minimize hazards to life and then property (including emergency shutdown or pressure reduction as necessary) and to meet the requirements of Field Operations and customers on a best efforts basis.  Establishing and coordinating communications between operations personnel and emergency responders as directed by Centra personnel to ensure that two way communications are maintained.  Contacting Centra Management Personnel as directed by Centra standby / operations personnel.  Utilizing members of the Gas Control Emergency Team to advise customers and suppliers of any reduction in system capacity that affect either supply or delivery, and recommend initiation of  Curtailment of interruptible customers and/or Force Majeure to match consumption to impaired throughput.  Providing support as requested by the operations person / standby operations person 2. Centra operations personnel could discover the condition during the performance of daily tasks or an emergency condition could result from a task that is being performed.Initial Response:Employee shall take appropriate actions to protect themselves and the public, notify appropriate emergencyresponse agencies, Gas Control, and Centra management personnel. Specific responsibilities include:  Determine through communication with Gas Control and site investigation, the extent of the emergency.  Based on findings, assign an initial emergency Level to the situation. If there is any doubt regarding the extent of the emergency, a Level 3 Emergency MUST be declared.  Start a Log of phone calls, including details of the conversation. It is also important to note whether calls made were in fact answered.  Take all steps possible that can be performed safely to control/manage the emergency and minimize hazards to life and then property (including evacuation of people, emergency shutdown or pressure reduction as necessary) and meet the requirements of Centra customers on a best efforts basis. Date: Manual Title: Page:25 May 2017 Emergency Management Program 17/47

Emergency Management Program ___ __________________________  Contact appropriate responder groups to aid and coordinate planned and actual responses with those groups. Maintain communications with emergency responder groups either directly or through Gas Control.  The exact assembly location will be identified by Centra personnel when they place the call requesting assistance. This location will be a safe distance upwind of the location where the emergency condition occurs.  Re – evaluate the emergency level once the extent of the emergency is known and act accordingly.  Call Centra operations personnel and request support as deemed to be necessary.  If required, after consultation with management personnel, call Contractor personnel to provide support.  Ensure management is kept informed of the events as they occur and follow directions given.Reports of potential emergencies are recorded on an Event Record in Quickbase.General ProceduresThe following procedures describe general guidelines for responding to and dealing with potential hazardsidentified with the operation of Centra natural gas facilities. Specific procedures will vary depending on the actualcircumstances associated with an incident.Protect LifeThe top priority in responding to emergencies is to protect life: 1. If emergency response personnel have not been notified call 911 or other emergency number for the Emergency Response Area (Section 1.5) in which the emergency is taking place. 2. Hazardous gas levels detected inside or near buildings represent an extreme hazard to life and property. Verify that any Centra or LDC customers that may have experienced unsafe operating pressures did not develop hazardous conditions within their facilities i.e. hazardous levels of gas inside. If hazardous conditions are found in customer facilities, evacuate the premises moving occupants to a safe location and follow procedures for Hazardous gas levels detected inside or near buildings. 3. If gas is detected outside, buildings adjacent to the area where the leak is detected must be checked as soon as practicable to determine if gas has migrated inside. If gas is detected inside a building, buildings adjacent to the affected structure must be checked for migrating gas. Any structures or areas where gas concentrations are hazardous or may become hazardous must be evacuated moving occupants to a safe location. Identify and remove any potential sources of ignition and ventilate structures when it can be done safely. Date: Manual Title: Page:25 May 2017 Emergency Management Program 18/47

Emergency Management Program ___ __________________________ 4. Move people and personnel away from the immediate area of the emergency to a safe location. Initial Emergency Planning Zone (evacuation distance) is a minimum of 800 feet (roughly just over 2 city blocks). This distance should be adjusted based on existing and changing conditions. 5. Determine the extents or perimeter of the emergency by checking the surrounding area for indications of hazardous conditions such as leaks inside and outside buildings, fires, etc. and immediately evacuate areas that are found to be hazardous or could potentially become hazardous. 6. When long term facilities are required to safely accommodate evacuees, employees will work with local officials to locate appropriate accommodations. 7. Make operational changes that curtail services to customers. This shall be done in accordance with the company’s Gas Curtailment Policy found in Annex 2.Protect Property and the EnvironmentAfter life safety concerns have been addressed, initiate actions that will protect property that may be involved inthe emergency: 1. Work with fire department officials to provide fire protection for structures and equipment that are endangered 2. Consider operational changes that can be made to mitigate the hazards and implement any changes that can be accomplished safely to reduce or eliminate the hazard without unnecessarily affecting service to customers. In extreme emergencies, the decision may have decision may have to be made to make operational changes that curtail services to customers. This shall be done in accordance with the company’s Gas Curtailment Policy found in Annex 2 of the Emergency Management Program.See Emergency Response Checklist in Annex 4. 2.4. Procedures for Identified HazardsThe following procedures describe general guidelines for responding to and dealing with potentialhazards identified with the operation of Centra natural gas facilities. Specific procedures will varydepending on the actual circumstances associated with an incident.Hazards or potential hazards resulting from natural disastersIn the area of Centra’s facilities the natural disasters that could potentially cause an incident includetornadoes, lightning, wild fire or flooding. Incidents could result in a hazardous leak(s), fire, explosion,unsafe operating pressures, and interruption of service. General procedures for each of these potentialhazards are specified below.  Facilities that may have been exposed to the damaging effects of natural forces must be inspected for leaks, damage and proper operation once the event has subsided.

Emergency Operations Center and Assembly AreasIn most cases the Emergency Operations Center (EOC) will be located at the pre-determined EOC designated bythe administrative authority in the area of the emergency operation.In remote locations, a mobile EOC may be necessary. If so, a rental travel trailer or RV can be utilized tohouse the EOC. The Contact Reference document, Annex 9 of the Emergency Management Program,contains contact information for Emergency Management Agencies in Manitoba, Minnesota, andOntario. These agencies also have mobile resources that may be called upon in an emergency. There isan EOC jump kit located at the Rainy River compressor station.In the event responder groups are required to respond to an emergency occurring on the transmissionsystem, the exact assembly location will be identified by Centra personnel when they place the callrequesting assistance. This location will be a safe distance upwind of the location where the emergencycondition occurs. Emergency Response Maps are provided in Annex 3. These maps can be used to planaccess to any part of the system, identify points to control unauthorized access and to identify potentialstaging areas depending on the location of the incident. Initial Emergency Planning Zone (EPZ) is aminimum of 800 feet. This distance should be adjusted based on existing and changing conditions. Thiszone is shown on the emergency response maps in Annex 3.
