Trans Mountain Pipeline ULC Consultation Report – Protection of Municipal Water Sources Trans Mountain Expansion Project January 2021

1.0 INTRODUCTION Trans Mountain Pipeline ULC (Trans Mountain) submitted a Facilities Application (the Application) to the National Energy Board (now the Canada Energy Regulator (CER)) in December 2013 for the Trans Mountain Expansion Project (the Project or TMEP).

On June 18, 2019, the Governor General in Council, on the recommendation of the Minister of Natural Resources, directed the National Energy Board to issue CPCN OC-065, and various Amending Orders, to Trans Mountain to permit the Project to proceed, subject to 156 conditions.

CER Condition 94 requires Trans Mountain file with the CER, at least two months prior to commencing construction, and on or before 31 January of each year during construction and for the first five years after commencing operations, a report (Consultation Report) on Trans Mountain’s consultations with municipalities and regional districts, communities, and Indigenous groups related to the protection of municipal and community water sources, including those sources currently relied upon and sources identified for potential future use.

Previous Consultation Reports include:

• The first Consultation Report, which included all consultation completed with local governments up to April 28, 2017 and Indigenous groups up to May 1, 2017, was submitted to the CER on June 16, 2017 (Filing ID: A84464); • The second Consultation Report, which included consultation with local governments and Indigenous groups up to December 31, 2017 (Filing ID: A89712-2); • The third Consultation Report, which included consultation with local governments and Indigenous groups up to November 1, 2018 (Filing ID: A97722-1); and • The fourth Consultation report, which included consultation with local governments and Indigenous groups up to December 31, 2019 (Filing ID: A7D0Z6).

This Consultation Report summarizes the CER Condition 94 consultation and engagement efforts from January 1, 2020 to December 31, 2020.

1.1 Commitment Management Trans Mountain made a number of commitments regarding the Project during the OH-001-2014 proceedings and engagement activities up to December 2020. Commitments were made to improve and optimize Project planning and mitigation measures. Trans Mountain has consolidated its commitments into a Commitments Tracking Table in accordance with CER Condition 6 and therefore the Table of Commitments in each plan has been removed. Information Requests (IRs) and engagement activities that raised discussion, but did not result in a commitment, are not included in the Commitments Tracking Table.

The updated Commitments Tracking Table has been filed with the CER pursuant to CER Condition 6 and will continue to be updated as per the condition requirements; the document is available on Trans Mountain’s website at www.transmountain.com. Trans Mountain continues to monitor and track compliance with its commitments and will update, post to its website, and file with the CER updated versions of the Commitments Tracking Table according to the timeframes outlined in CER Condition 6. Commitments with specific relevance to this Consultation Report have been considered and incorporated in the report.

N/A Chilliwack the Condition 94 report.

Trans Mountain provided a response by email clarifying that review by the Project assessment team determined that the significance conclusions of the ESA regarding water quality and quantity remain unchanged from the previous route. Trans Mountain has a comprehensive suite of mitigative tools to prevent the risk of contamination to the Coldwater River and Upper Merritt Aquifer, including:

The City asked Trans Mountain whether the West • Pipeline EPP (Filing ID C01961) including the Groundwater Alternative Route Variance (re-route) would introduce any Management Plan City of December additional contamination risk for the Coldwater River or • Post-construction environmental monitoring (Condition 151) Groundwater Email N/A Merritt 2020 Upper Merritt Aquifer and whether this new western • Hydrogeological Study at Coldwater Information Request No. 1 alignment would have any impact on Coldwater River flow (Filing ID A7F6Y6) levels. • Water Well Inventory (Filing ID A84458) • Watercourse Crossing Inventory (Filing ID C00815) • Consultation reports – protection of municipal water sources (Condition 94)

Given that the proposed primary and contingency crossing methods for the two Coldwater River crossings are trenchless, no instream works will be required and there will be no impact to flow

3.0 INDIGENOUS ENGAGEMENT Since April 2012, Trans Mountain has engaged with Indigenous groups who might have an interest in the Project or whose territory may be potentially affected by the Project. This is based on the proximity of their community and their asserted traditional and cultural use of the land along the pipeline corridor to maintain a traditional lifestyle. The objectives of Trans Mountain’s Indigenous engagement program are to:

• have an open, transparent and inclusive process that seeks to exchange information in a respectful manner;

• address concerns shared by those who might have an interest in the Project or have Indigenous interests potentially affected by the Project;

• incorporate feedback into Project planning and execution; and

• provide opportunities to maximize Project benefits to Indigenous groups.

A comprehensive Indigenous engagement program is led by experienced Indigenous Relations Advisors in Alberta and British Columbia, specialized in the areas of Indigenous relations, law, economic development, education, training, employment and procurement. Trans Mountain’s Indigenous engagement efforts remain flexible, allowing each community and group to engage in meaningful dialogue in the manner they choose and in a way to meet their objectives and values.

Indigenous groups had the opportunity to engage with Trans Mountain, depending on Project interests and potential effects. The following opportunities to engage have been provided:

• Project announcement;

• initial contact with the Indigenous group;

• meetings with the Chief and Council, including staff;

• community information session(s);

• conduct Traditional Land Use (TLU) studies and socio-economic interviews, including sharing of Traditional Ecological Knowledge (TEK);

• identify interests and concerns; and

• identify mitigation options.

Detailed information on Indigenous engagement activities specifically related to the protection of municipal water supplies that were conducted from January 1, 2020 to December 31, 2020, are summarized in Table 3. The engagement activities generally occurred at Indigenous community offices, open houses and mutually agreed-upon locations. However, following the March 19, 2020 World Health Organization (WHO) declaration regarding the COVID-19 pandemic, Indigenous engagement activities continued virtually, and in compliance with travel and in-person meeting restrictions. When possible, and with strict adherence to COVID-19 guidelines, in-person meetings occurred in the field during collection of TEK, concurrent with biophysical field studies.

Trans Mountain’s complete record of Indigenous engagement is available within its various CER Condition 96 filings. The most recent Condition 96 Report was filed in January 2021, covering the period of January 1 to June 30, 2020 [Filing ID C11031-1].

4.0 GROUNDWATER MODELLING OR MONITORING Trans Mountain is currently in the process of preparing a Groundwater Monitoring Plan as required under CER Condition 130. The Groundwater Monitoring Plan includes a focus on drinking water resources sourced from vulnerable aquifers.

Trans Mountain completed a hydrogeological assessment of the Coldwater Aquifer underlying the Coldwater Indian Reserve No.1 (Coldwater IR) and submitted that report as required under CER Condition 39. The Condition 39 report was submitted to the CER on May 15, 2020 [C06341]. A summary of consultations and field work activities completed at Coldwater IR was included in the CER Condition 39 filing.

Trans Mountain will continue to encourage feedback from Indigenous groups and local governments under CER Condition 94. Feedback obtained will be reviewed and will be considered to guide groundwater modelling or monitoring efforts to ensure the potential for impact on water sources is minimized as the Project moves forward. All modelling or monitoring completed to ensure the protection of municipal and community water sources will be summarized and included in future CER Condition 94 filings.
