  The proposed Keystone XL project is a partnership between TransCanada and ConocoPhillips. In the US, the permanent right-of-way easements will be 50 feet (15 meters) wide, with an additional 60 feet (18 meters) of temporary workspace.In addition, in both Canada and the U.S., additional temporary work space will be required at certain highway, railway, existing pipeline corridors watercourse crossing and at other site specific locations, to accommodate pipeline construction activities. Crude oil pipeline construction involves burying continuous sections of pipeline underground and building above-ground facilities to support the pipeline operation. Above ground facilities for the Keystone XL Pipeline will include 41 pump stations (33 in the U.S. and 8 in Canada), which essentially push the crude oil through the pipeline.Subject to receiving the required regulatory approvals, construction of Keystone XL is planned from 2010 to 2011. A number of construction crews or spreads will be working simultaneously on different sections of the pipeline route in Canada and the U.S. Each spread will have a peak workforce of approximately 500 to 650.

Public and employee safety, as well as environmental protection, are key elements in the planning of pipeline construction.No construction work will begin until commercial agreements are in place, regulatory approvals have been received and easements have been acquired from landowners. The Right-of-Way Pipelines are built on rights-of-way, which are strips of land where the pipeline company has acquired easement rights to safely construct and operate the pipeline.In Canada, the permanent right-of-way easements will vary from 13 to 20 meters (42 to 66 feet) with an additional 12 to 19 meters (40 to 63 feet) of temporary work space required.  The proposed Keystone XL protect is a partnership between TransCanada and ConocoPhillips. 1246 Sequence of Typical Construction Activities 1. Clearing and grading the right-of-way Trees, brush and crops are removed and a working surface is then prepared by stripping off the topsoil layer and grading the subsoil to create a level work surface. The topsoil is preserved separately from the subsoil so that it may be returned to the right-of-way after construction. 2. Stringing the pipe The pipe, which has been pre-treated with a corrosion inhibiting coating, is distributed in varying lengths along the right-of-way (up to 24 meters, or 80 feet), then bevelled and bent to suit the contours of the land and, finally, prepared for welding. 3. Welding / Inspection Sophisticated technology is used to weld the pipe together in one string and each weld is inspected to meet strict safety and quality assurance requirements. 4. Ditching, coating and installing pipe Excavating equipment is used to dig the ditch. Then, the pipe is placed in the ditch. Finally, the welded joints are coated for corrosion protection and the pipeline is inspected. 5. Backfilling and final cleanup The subsoil is used to cover the pipe in the trench and is then covered with the srcinal topsoil. 6. Right-of-way reclamation Care is taken to return the land to a condition as close as possible to its previous state (prior to construction). Environmental protection plans are implemented to stabilize the right-of-way and promote the re-establishment of a vegetative cover, where appropriate. 35 Contact  For more information, please call our toll free project number (1.866.717.7473) or use our project-specific email address keystone@trans-canada.comAlternatively, you can refer to our website at write attention to: In Canada TransCanada Keystone XL Project Team450 – 1st Street S.W.Calgary, AlbertaCanada T2P 5H1 In the U.S. TransCanada Keystone XL Project Team7505 NW Tiffany Springs ParkwayNorthpointe Circle II Suite 400Kansas City, MO 64153 Landowner Inquiries Canada (toll free) 1.866.412.5263U.S. (toll free) 1.866.585.7063 Pipeline   Construction  In the process of constructing a pipeline, TransCanada takes great care to maintain the productive capability of all lands disturbed by construction by implementing topsoil conservation procedures throughout the project. This activity hastens restoration and maintains the land’s productive capability for future generations. As part of the process of developing an environmental protection plan, TransCanada undertakes a soil survey of all lands with agricultural capability. Soil surveys document the soil characteristics on all agricultural lands crossed by the proposed pipeline. The soil survey identifies the soil type, physical characteristics and depth of topsoil. This information is used to determine the depth of topsoil stripping required and the appropriate soil handling procedure for each quarter section. This information is documented on the environmental alignment sheets that are included in the environmental protection plan.Soil surveys and the current land-use are combined to develop an appropriate soil handling procedure for each parcel of land traversed by the pipeline. The objective is to establish procedures to minimize the degradation of topsoil from mixing, compaction, rutting, or loss of organic matter.To avoid soil mixing, topsoil is salvaged and stored separately from subsoil and other construction related activities. After pipeline installation is complete, subsoils are replaced in the trench and disturbed right-of-way to re-establish the land’s natural contours, and then the topsoil is spread across the disturbed area Topsoil handling components: ã Stripping removes and stores up to 12 inches of topsoil; less in areas where there is less topsoil. ã Topsoil is usually stored in a windrow at the far edge of the right-of-way. In rare cases, it can be stored in other locations. ã If grading the right of way is necessary for construction, topsoil is stripped from the entire right-of-way to avoid mixing.ã In native prairie and typically in pastureland (where grading is not necessary), stripping is limited to the trenchline only to minimize impact and disturbance to the vegetation.ã Generally, limiting the area where topsoil is removed to the area where excavation will occur helps minimize overall impact.ã Soil resources are monitored during construction to avoid compaction and rutting. If required, soils may be stabilized to prevent or minimize wind and water erosion. The stabilization method utilized would be determined in consultation with the landowner.The following description of different topsoil management methods is provided for informational purposes. Keystone project personnel and land agents can help landowners determine what may be most appropriate for their land. Pipeline Construction Topsoil Management The proposed Keystone XL project is a partnership between TransCanada and ConocoPhillips.  Trenchline Only Topsoil Stripping: In the “Trenchline Only” topsoil stripping method, topsoil is removed only from the area where the trench will be excavated. As shown in the drawing below, the topsoil is typically stockpiled along the edge of the right-of-way. When the trench is excavated, the subsoil is placed adjacent to the trench. It is returned to the trench after the pipeline has been lowered in. The topsoil is handled separately from subsoil and is replaced over the trenchline after subsoil is replaced within the trench. This topsoil stripping method requires less construction workspace and less disturbance to the topsoil layer across the right-of-way. Pipeline Construction   Topsoil Management The proposed Keystone XL project is a partnership between TransCanada and ConocoPhillips. Trench and Spoil Topsoil Stripping  Topsoil is stripped and conserved from the trench and spoil side of RoW. Trench subsoil is placed on the area cleared of topsoil and then is replaced in the trench once the pipe is lowered in. Topsoil is replaced over the trench and the subsoil storage area during clean-up. This method can prevent mixing from subsoil storage on unstripped land, but requires more space and increases the disturbed area. In addition, stripping of the larger area is typically done in advance of trenching Generally, this method of topsoil conservation is used on haylands or improved pasture lands. Full-Width Topsoil Stripping  Topsoil is stripped and conserved from the entire right-of-way including the workside, trenchline and spoil storage areas. By removing topsoil from the workside, equipment can travel along the right-of-way, even under adverse soil moisture conditions while avoiding any potential for topsoil degradation through soil compaction or rutting. On the spoil storage side of the right-of-way, the potential for mixing of stored subsoil with topsoil is also avoided. However, this stripping procedure requires significantly more space for adequate topsoil storage and will result in the disturbance of the entire construction right-of-way area. In addition, stripping of the larger area is typically done in advance of trenching.
