Kamloops, BC V2C 6N6 Swift Creek Pipeline Remediation December 2010 Disclaimer This report is rendered solely for the use of Kinder Morgan Canada Inc.in connection with the Swift Creek Pipeline Remediation Project, and no person may rely on it for any other purpose without Triton Environmental Consultants Ltd.’s prior written approval. Should a third party use this report without Triton’s approval, they may not rely upon it. Triton accepts no responsibility for loss or damages suffered by any third party as a result of decisions made or actions taken based on this report. The objective of this report is to provide a screening level environmental assessment based on baseline information regarding aquatic habitat, channel morphology, terrestrial wildlife, vegetation, and archaeological resources. The screening level environmental assessment will be used as the basis for regulatory agency approvals of the proposed Project on behalf of Kinder Morgan Canada Inc. This report is based on facts and opinions contained within the referenced documents and Project background information. We have attempted to identify and consider relevant facts and documents pertaining to the scope of work, as of the time period during which we conducted this analysis.
