1. Hyperlinks to AUC filings require an AUC eFiling login which can be obtained by contacting the AUC. 2. For NGTL projects greater than $25 million, the estimate type for the forecasted costs have been provided. The typical expected accuracy for the various estimate types are shown in the table below. These accuracy ranges are for projects with established technological complexity and can be greater depending on area knowledge, technological complexity, level of expertise, and certainty of facility scope. Forecasted costs reflect the dollar value, economic conditions, and estimation procedures at the time the estimates were completed. Estimate Type Expected Accuracy Range Rule of Thumb (ROT) (-50% to +100%) Class 5 (-20% to +30%) Class 4 (-15% to +20%) Class 3 (-10 to +10%)

45 NOVA Gas Transmission Ltd. Appendix 2: 2019 Facility Status Update (December)

3. Total Costs by In-Service Year are a summation of the last provided costs of all NGTL capacity capital projects with expected or realized in-service dates within a calendar year. Costs for non NGTL capacity capital projects, such as ATCO Pipelines, CIAC, decommissioning or abandonment projects, are excluded. These annual summations of costs will not match other regulatory filings with different costs bases. 4. Variance explanations are provided for all NGTL capacity capital projects with EAC costs equal to or greater than $25 million with a variance greater than 10% between the EAC and applied-for costs. 5. The North Montney Project was filed as a Section 52 application on November 8, 2013 comprised of the following facilities: North Montney Mainline (Aitken Creek Section), North Montney Mainline (Kahta Section), Aitken Creek Compressor Station, Saturn Compressor Station, Groundbirch Compressor Station, 14 receipt meter stations, a bi-directional storage meter station (Aitken Creek Interconnect) and a delivery meter station (Mackie Creek Interconnection). The NMML Variance was filed March 20, 2017 to vary Condition 4 in the Certificate and Order and to extend the Sunset Clause for the NMML. The Variance also includes the details on eight additional meter stations required for the new receipt contracts. North Montney costs are escalated to the year of in-service for each respective facility. The original Kahta Section was 119 km of NPS 42 with a ROT cost estimate of $530Million. Variance Application NEB Approval Order Received May 23, 2018. Altares, Altares South, Gundy, Gundy West, Old Alaska, Mackie Creek North, Townsend, Townsend No. 2 and Aitken Creek South receipt meter stations are currently under construction. 6. Northwest Mainline Loop No. 2 (Bear Canyon North Section) is the combination of two previously presented facilities; Northwest Mainline Loop No. 2 (Bear Canyon North Section) and the Northwest Mainline Loop (Peace River Crossing Project). 7. Turner Valley Compressor Station Coolers has been combined with Turner Valley Compressor Station Unit Addition.
