22 Properties of Natural Gas/Methane Gaseous (not liquid) Lighter than air 4-15% LEL UEL (Lower/Upper Explosive Limit) 22

23 Visual Indication of a Gas Leak Blowing dust and debris, indicative of venting gas Bubbles and unusual turbulence in water (i.e., river crossing) Suspect holes, erosion or signs of ground movement around the pipeline Dead vegetation over the pipeline 23

24 In the Event of a Gas Leak Priorities: life, the environment, property and restoration of service Notify facility owner and local Emergency Response Personnel Local emergency response personnel will assist with evacuation, ignition prevention, establishing a perimeter, crowd control, media, etc. Facility owner should be notified immediately, so they can render the situation safe, activate isolation valves, properly vent, prevent ignition, perform repairs and restore service 24

25 In Case of Fire: Don t try to extinguish the fire Don t use water on the burning gas at the point of the fire Do spray water on nearby buildings or other combustible material to help prevent the fire from spreading 25

26 In Case of Gas Inside a Building If you detect escaping gas inside a building: Do not attempt to locate the gas leak(s) Do not remain in a building or area where there is a strong gas odor Do not turn lights on or off, or unplug electrical appliances when there is a strong gas odor Do not use telephones in the area of a strong gas odor Do not use elevators Do not position or operate vehicles and powered equipment where leaking gas may be present Leave the area and call the gas company 26

28 The Moyie River and GTN The GTN system crosses the Moyie River eight times. The 1992 expansion required GTN to cut through the river, disturbing the sedimentation and increasing turbidity of the river. This expansion project created an opportunity for GTN to enhance the river and demonstrate the company s respect for the area s natural resources. 28

29 Moyie River Enhancement Plan and Results With the help of the U.S.Forest Service and Geomax engineering 35 rock structures were tailor-made for each crossing. The fish structures improve fish habitat, accelerate stream scouring, and enhance the depositional regime. For five years following the construction ( ), GTN monitored the impact of our enhancement efforts. Results showed a 400% increase of the fish population. 29

33 Joseph P. Kearney Environmental Excellence and Stewardship Award Finalist John Cassady, Gas Transmission Northwest for the development and creation of the Moyie River Recreation Site 33 Kaniksu Passage at the Moyie River Recreation Site Near Moyie Springs, Idaho Unveiled June 29, 2001

34 Kaniksu Passage Funk s sculpture was selected because it: incorporates the entire picnic site; includes images of species indigenous to the river; materials can withstand the area s natural elements. Kaniksu Passage is the first sculpture in a national forest. 34

35 Impacts on the Community The recreation site has given residents and visitors a place to enjoy the natural beauty, eat a peaceful lunch, or walk down to the river. In a letter to Bob Howard, Jean Mace, a resident of northern Idaho and a frequent visitor of the recreation site, described it as, One of Boundary County s hidden treasures. 35

36 Jeffrey Funk is acknowledged for his great creativity and talent in sculpting Kaniksu Passage. 36

37 Guests enjoy the picnic facilities and the beautiful surroundings. 37
