Document: 331165 DECISION AND ORDER M12904 NOVA SCOTIA ENERGY BOARD IN THE MATTER OF THE PETROLEUM PRODUCTS PRICING ACT - and - IN THE MATTER OF PRESCRIBING PRICES for Petroleum Products under

Section 14 of the Petroleum Products Pricing Act and Sections 16 to 19 of the Petroleum Products Pricing Regulations BEFORE: Bruce H. Fisher, MPA, CPA, Member DECISION AND ORDER Under s. 16 of the Petroleum Products Pricing Regulations , the Board must prescribe a benchmark price for specified petroleum products every Friday. However, the Board may prescribe a benchmark price any time, and due to significant changes in the price of petroleum products, the Board has determined that it is appropriate to adjust its most recently prescribed weekly prices.

The benchmark price prescribed by the Board is the average of the average of the daily high and low reported product prices (in Canadian cents) since the last benchmark price adjustment for the petroleum product. Under s. 17 and 18 of the Petroleum Products Pricing Regulations , the Board must also prescribe retail mark -ups and calculate wholesale margins considering any factors the Board finds relevant, including transportation adjustments. The Board set new retail mark-ups, on an interim basis, pending a full investigation, in a Decision Letter and Interim Order, both dated May 26, 2026.

The Board last confirmed wholesale margins in its Decision, 2025 NSEB 14; and transportation adjustments in its Decision, 2016 NSUARB

Section 17 of the Petroleum Products Pricing Regulations also requires that the fixed wholesale price for each type of petroleum product include all taxes (taxes imposed under subsections 165(1) and 165(2) of the Excise Tax Act (Canada) ; carbon pricing, any fuel charges payable to His Majesty in right of Canada, a clean fuel adjustor amount set by the Board under s. 17A to address the financial and administrative burdens associated with the application of the Clean Fuel Regulations (Canada) or any other regulatory instrument made under the Canadian Environmental Protection Act, 1999 (Canada) and

- 2 - Document: 331165 the Environmental Violations Administrative Monetary Penalties Act (Canada) ). The Board last revised and set the clean fuel adjustor amount in its Decision, 2025 NSEB 14. The Board also issued an Order on September 12, 2022 [2022 NSUARB 140], approving an adjustment mechanism to retail mark-ups for gasoline and diesel oil to account for the impact of credit card fees charged to retailers. This adjustment mechanism was updated, on an interim basis, pending a full investigation, in its Decision Letter and Interim Order, both dated May 26, 2026.

At each price setting, the Board may apply a forward averaging correction, based on historical prices, to achieve revenue neutrality. At appropriate times of the year, the Board may also require an additional margin for winter blending of ultra-low-sulfur diesel oil. Based on the foregoing and other requirements in the Petroleum Products Pricing Act and Regulations, the Board finds it appropriate to prescribe the benchmark prices and adjustments in Table “A”, the credit card fee retail mark-up adjustments in Table “B”, the Clean Fuel Adjust or in Table “C”, and the prices for Petroleum Products in
