You may be aware that much of our pipeline system is buried underground but other facilities related to our business are above ground (e.g. compressor stations, meter stations, valves, etc.). You are receiving this letter because a portion of our pipeline system is located in your area and we want you to be aware of the role you can play in ensuring it is operated safely and reliably. We have enclosed a map of our pipeline that lies within a high consequence area in your community. In accordance with federal regulations, Williston Basin Interstate Pipeline Company has prepared a plan for managing the integrity of the pipeline segments that lie within High Consequence Areas (HCA's) in your community. From last year's mailing you should recall that an HCA is considered to have the potential of endangering large numbers of people should a pipeline failure occur. In general, these areas can be described as: • Areas that meet certain criteria of high population density • Areas that contain populations of impaired mobility (e.g. schools, hospitals, etc.) • Areas where people congregate (church facilities, parks, ball fields, etc.) To meet Williston Basin's goal of protecting people, property and the environment, pipeline damage prevention measures are regularly taken, including routine inspection and maintenance, corrosion protection, continuous monitoring, pressure control, public awareness program, integrity management, and emergency response plans. Toward these goals, it is important that you are familiar with our pipeline facilities in your community and the safety information contained on the back of this letter. Only by working together can we achieve the highest standard of safe operation of the pipeline. Thank you for taking the time to allow me to share this important information. Williston Basin Interstate Pipeline Company hopes you have a better understanding of our concern about the safety of those in the communities where we are located. If you notice any suspicious activity near our pipeline, call our emergency number 1- 888 - 859 -7291. If you have questions or would like further information about our Pipeline Integrity Plan and how it relates to HCA's in your area, please contact me, 1-406- 359 -7316 and I will promptly respond to your inquiry. Sincerely, DOy1, 2 010 Don Johnson Pipeline Safety Awareness Coordinator For additional information, please visit us at www.wbip.com =WILLISTON BASIN INTERSTATE PIPELINE COMPANY About Williston Basin Interstate Pipeline Company Williston Basin Interstate Pipeline Company operates at least 3 .700 -miles of natural gas pipeline with pipe ranging in diameter from 2 to 16 inches. Williston Basin traces its roots to the 1920's when short-haul natural gas pipelines were constructed to connect towns in North Dakota, South Dakota and Montana with several of Montana's natural gas fields. This gas transmission system was known as the Gas Development Co and its parent company was Montana Dakota Utilities Co. a predecessor company of the now current MDU Resources Group, Inc. For more historical and public awareness information please, visit our website at www.wbip.com. Our facilities are for the most part located underground. These pipelines traverse farmlands, rivers, creeks, lakes and streams. They also cross highly populated areas, areas adjacent to industrial and commercial locations, and many highways, interstates, county roads and city streets. We need your help Most pipeline accidents occur when individuals are not aware of a pipeline's location before they begin their work. You can help prevent pipeline incidents by calling the national "Call Before You Did" number, 811. When you call 811, information ion is routed to your state agency where Williston Basin Pipeline Company and others in the area are notified.

Call balm will& Pipeline markers Pipeline markers are located at road and river crossings, fence lines, and property boundaries. These pipeline markers contain information about contacting our company in the event of an emergency, or when construction is necessary in the vicinity. You IR may find several types of pipeline markers along our system but the placement follows a consistent pattern. If damage occurs If one of our pipelines is damaged, even if the damage only appears to be minor, please notify Williston Basin Interstate Pipeline Company immediately. It is important that we evaluate and have the opportunity to repair any damage, no matter how minor. How to recognize a leak Natural gas is a colorless, odorless fuel that is lighter than air. Because natural gas can not be detected on its own, local utilities add a harmless odorant to help consumers smell gas should a leak occur. However, odorant is added at only certain places along the pipeline, so you may not always be able to detect a leak by smell. There are several other ways to detect a leak: • A hissing sound • Dirt being blown or thrown into the air • Water being blown into the air at a pond, creek or river • Dead grass or vegetation • Fire apparently coming from the ground or burning above the ground • Dry spot in a moist field In case of emergency If released, natural gas will rise and diffuse rapidly. If you should happen to be working in the area of a broken, leaking or damaged pipeline, abandon equipment immediately and notify Williston Basin Interstate Pipeline Company as soon as possible. Escaping gas can be ignited by open flames or sparks from electrical switches, motors, mechanical equipment or flying rocks. Williston Basin Interstate Pipeline Company emergency toll -free phone number can be found on all pipeline markers, 1- 888 -859- 7291. We will arrive soon Pipeline emergency action will begin the moment we become aware of the situation. Williston Basin Interstate Pipeline Company personnel and equipment will be dispatched to identify the emergency, control the flow of gas and make necessary repairs. We will coordinate our actions with fire, police and other public officials. Emergency response for public safety personnel Fire, police and other public officials participating in a pipeline emergency should do whatever they deem necessary to safeguard the public. Such action should include clearing the area of people, barricading the area and standing by at a safe distance. If gas ignition has not occurred, precautions should be taken to prevent ignition, such as prohibiting smoking and rerouting traffic. Where gas is burning, prevent the spread of fire but do not attempt to extinguish the burning gas. Also, do not attempt to operate the valves on our pipelines. 24 -hour emergency number: (888) - 859 -7291 Williston Basin Pipeline HCA s -- �,= _ . within Yellowstone County - L 4 �" • � ' �„ Ponderosa Town Homes Baker Transfer and Storage HCA- - ►� ;_ �`' -. � Intermountain HCA/P K • I.
