Suite 2700, 300 – 5th Avenue S.W. Calgary, Alberta T2P 5J2 Ph: 403-514-6400 ENVIRONMENTAL ALIGNMENT SHEET GUIDE GENERAL INFORMATION The Environmental Alignment Sheets (EAS) provide information pertaining to the environmental and socio-economic setting above the Photomosaic. Potential environmental and socio-economic issues identified during Project planning, and their corresponding mitigation measures, are positioned below their respective location on the Photomosaic. Resource-specific Environmental Notes are included below the Photomosaic, outlining mitigation measures to be implemented during Project construction. These measures are further described in the Environmental Plans, specifically the Pipeline Environmental Protection Plan (Pipeline EPP) (Volume 2 of the Environmental Plans), the Environmental Management Plans (Volume 6 of the Environmental Plans) and the Resource Specific Mitigation Tables (Volume 7 of the Environmental Plans). The mitigation measures included on these Index Sheets do not include all of the potential mitigation measures that may be implemented; please consult the Environmental Plans for additional protection measures as necessary. Contingency plans providing guidance for events where previously unidentified environmental features are encountered can be found in Appendix B of the Pipeline EPP. Drawings can be found in Appendix C of the Pipeline EPP.
