TMX ANCHOR LOOP PROJECTBegan in Jasper August 2007 and was complete October 2008. Built in the early 1950s, the TransMountain pipeline is a 1,150 kilometer petroleum products pipelineThe Canada National Parks Act does not provide for any new utility corridors through nationalparks. Kinder Morgan Canada inherited provisions granted in the 1950s that allowed the TMXAnchor Loop to progress.
RestorationRequirementsKinder Morgan undertook acomprehensive environmentalassessment of the pipeline routeThe pipeline right of way was tobe restored to its pre-disturbancestate, post constructionmonitoring is to continue for atleast 5 years. Evaluation includesreclamation success, vegetationestablishment, erosion controland weed growthPart of the agreement on top ofrestoration of the pipeline rightof way was for Kinder Morgan tocommit to enhancing ecologicaland commemorative integrity inJasper National Park. Thisprogram was called the “NetGains Program”
Miette River CrossingIn total there were 43river crossings that wereaffected by the pipeline.At this location a damwas installed to haltwater flow and pumpswere used to divert thewater around theconstruction area. Pipewas installed and waterflow resumed in a 24hour period.
Restoration ReplantedFor seed bed stability heavy equipment Pine,operators packed the soil so their tracks were Mountainperpendicular to the slope. This provided a Alder andprotected soil base for seeds to establish locallywhile preventing erosion from wind or water native shrubs on both banks to match the naturally occurring forest vegetation
A bank root zone was re-established for an appropriate foundation for the establishment of newly planted native woody speciesThe sandbar on the right bank was replacedalong with large stones and cobble alongthe flow level of the left bank to predisturbed conditions
Construction panel fencing was used to limit wildlife access to the newly establishing saplings, forbs and grass species.The bank was recreated using biodegradable wraps filled with local soil and layered with live willow stakes.
Miette WetlandLocated near the CN rail line the MietteWetland ran a 4 kilometer strench and posedquite the change as a restoration project.
Restoration Wetlands are an important wildlife area with sensitive soils. To reduce damage to wetland vegetation during pipeline construction, all work was completed during the winter months. Frost was packed along the right of way andthen additional ice was made on that surface. Aditch wheel was used to excavate the trench.This method ensured a narrow ditch, disturb lesssoil, and require less soil storage area resulting inminimal disturbance to the area.
Variousnative woodyand riparianvegetationspecies werecollected andtransplantedback to thissite. This ensured that the same structure and function was restored to the wetland in a pre- disturbed state.
Weed/invasive specie control is critical in any restoration success. We discoveredCanola, barley and wheat growing on CN rail line adjacent to the Miette Wetland.
Apple Moss Haller’s Apple Moss (Endangered) was discovered in an area near the pipeline right of way. Maintaining the sensitive habitat of this moss was overlooked. Mature trees were removed, which provided the necessary components for this species survivalNegative effects of canopy removalraises air temperature and lightintensity, and decreases relativeHumidity which is essential in theHaller’s Apple Moss survival.
A burlap screen wasconstructed to simulate amoist, shady growingenvironment until newlyplanted trees areestablished. Relativehumidity and temperatureare being monitored atthis site to determine theeffectiveness ofrestoration efforts. Relative humidity and temperature data collected over two growing seasons (2008, 2009) suggest that the habitats that Haller’s Apple Moss occupy have a higher mean relative humidity and lower mean temperature then nearby microhabitats at the same sites.

Pipeline Right of Way East of JasperDirectly north ofhighway 16, this siteis used by elk and bighorned sheep forcalving, rutting and aswinter forage range.Initial restoration ofthis site wasunsuccessful as highlevels of erosionoccurred along theslope.
RestorationDuring the post-constructionphase the soil was preparedin a manner whichencouraged water erosion.Crews had to return tocreate erosion control ridgesand add matting to slow thepronounced drainage ofwater .
The slope wasreseeded withunpalatable grassesand forbs todiscourage wildlifegrazing along thehighway. A log railfence was thenerected aroundrestoration site. Thisstyle was selecteddue to its naturalappearance thatwould be moreappealing to publicperception andrestricting wildlifeaccess.

Exam QuestionsWhat was the purpose of restoring the Miette wetland in the winter?What detail was overlooked while dealing with Haller’s Apple Moss?On the Miette wetland, why is there still a visible path where the pipeline right of way is afteralmost 3 years?Why was Kinder-Morgan allowed to build a petroleum pipeline through Jasper National Park?List some groups needed to be consulted before construction started on the TMX Anchor loopPipeline?List some considerations that needed to be made when diverting water during a river crossingconstruction?What methods were used to seed native grasses in JNP?What considerations were made with construction scheduals with reguards to wildlife?What were some important things to think about while dealing with the “appearence” of thepipeline project?Jenny claims to have seen eyes in the dark durning our stay at Cadamin campground. What was thelikely species she saw? Werewolf, Yogi bear, ground Squirelle or the Saber Toothed species that JoshID at the wetland restoration site
