Attention: Ms. Sheri Young, Secretary of the Board

Dear Ms. Young:

Re: NOVA Gas Transmission Ltd. (NGTL) Pipeline Maintenance Program – NGTL System (Multiple Locations, AB) Notification of Ground Disturbances within 30 m of a Water Body or Wetland

In accordance with the provisions of the National Energy Board’s (Board) January 2013 Amendment to Regulation of Operations and Maintenance Activities on Pipelines under the National Energy Board Act (O&M Guidelines), NGTL notifies the Board that it will be conducting investigative digs using power-operated equipment as part of its pipeline maintenance program within 30 m of a water body or wetland (Work). The Work will be conducted on the NPS 16 Mainline, NPS 36 Grande Prairie Mainline and NPS 24 Grande Prairie Mainline Loop. For the locations of the planned activities, see Table 1. This Work is part of the ongoing pipeline integrity and maintenance program on the NGTL System.

Work will consist of stripping topsoil, excavation, coating removal, pipe assessment, repair (if required) and recoating. The sites are entirely contained in the existing rights-of-way.

Where Work occurs within 30 m of a water body or wetland, NGTL will apply measures to ensure Work is completed in a manner that mitigates impact, if any, on the water body or wetland. NGTL will retain an environmental inspector, as required, to ensure control measures during construction activities at the site are implemented appropriately. NGTL will modify or suspend Work, as recommended by the environmental inspector, if there is potential for adverse impacts on the water body or wetland.

If Work is planned to occur in a fish-bearing water body, or in a water body with connectivity to a fish-bearing water body, a fish habitat assessment will be completed, and recommended mitigation measures to avoid Serious Harm will be implemented. For the description of the water body or wetland, see Table 2. December 4, 2014 Ms. S. Young Page 3 of 6

If fish or fish habitat are found, NGTL will follow current practices as outlined in Department of Fisheries and Oceans ’s (DFO’s) Measures to Avoid Causing Harm to Fish and Fish Habitat. Standard mitigation measures for low-risk in-stream activities will be applied as described in DFO’s former Operational Statement for Isolated or Dry Open-Cut Stream Crossings and Alberta Environment and Sustainable Resource Development’s Code of Practice for Pipelines and Telecommunication Lines Crossing a Water Body.

TransCanada PipeLines Limited’s operating procedures and standards will be used to conduct the Work. Environmental protection measures are included in the site-specific environmental protection plan implemented for the Work. Work is expected to begin no earlier than January 8, 2015 and to be completed no later than April 8, 2015. NGTL confirms that all interested parties have been notified of the proposed Work and that there are no unresolved third-party concerns. NGTL will work with stakeholders to address any questions or concerns should they arise.
