TRANS MOUNTAIN EXPANSION PROJECT: NONFISH-BEARING ATLAS Pipeline and Power Lines Supplemental Fisheries (British Columbia) Technical Report: Appendix C1 Prepared for: Trans Mountain Pipelines ULC Calgary, Alberta Submitted by: Triton Environmental Consultants Ltd. Kamloops, British Columbia December 2014 SREP-NEB-TERA-00030 Trans Mountain Expansion Project Appendix C1: Nonfish-Bearing Atlas – Pipeline and Power Line NONFISH-BEARING ATLAS Pipeline and Power Lines PREPARED AS APPENDIX C1 OF THE SUPPLEMENTAL FISHERIES (BRITISH COLUMBIA) TECHNICAL DISCIPLINE REPORT Trans Mountain Expansion Project Appendix C1: Nonfish-Bearing Atlas – Pipeline and Power Line GLOSSARY OF TERMINOLOGY, ABBREVIATIONS, AND SYMBOLS USED IN THE NONFISH- BEARING ATLAS FOR PIPELINE AND POWER LINES Fish Habitat Potential Description of the assessed habitat potential per species and life stage considered. N None L Low M Moderate M-H Moderate - High H High Species Acronyms are provided on Page xii of the Supplemental Fisheries (British Columbia) Technical Discipline Report. Sampling Effort EF Electrofishing. Effort measured in seconds (s). MT Minnow trap. Effort measured in hours (h) of trap deployment. All traps were Gee Type minnow traps (baited). Least Risk Window Proposed QEP-recommended preferred period of time for construction, with consideration for the associated Provincial Window of Least Risk and habitat potential identified within each Fish and Fish Habitat LSA. Classification Watercourse Class designation as determined by BC Oil and Gas Commission (BC Oil and Gas Commission 2012). Navigability The ability of the watercourse to be traversed by any type of floating vessel for the purpose of transportation, recreation or commerce, as determined by the field crew. Navigability status definitions and the screening criteria used to make field based determinations are outlined in Section 3.3 of Technical Report 5C-7 in Volume 5C, Fisheries (British Columbia) Technical Report (Triton December 2013; Filing ID A3S2C1). Mean Channel Width The average distance between the ordinary high water mark of both right and left banks within the LSA. Proximity to Other Watercourses The name of and distance to the nearest downstream or downslope watercourse with fish bearing status (FB) identified, where known.
