During the year ended December 31, 2018, we recorded $33 million (2017 – $121 million) of additional study and environmental costs arising from legal obligations through other provisions. Decommissioning and Restoration Provisions The decommissioning and restoration provisions represent the present value of estimated costs for required future decommissioning and other site restoration activities. The majority of the decommissioning and site restoration expenditures occur at the end of, or after, the life of the related operation. Our provision for these expenditures was $1,160 million as at December 31, 2018. After the end of the life of certain operations, water quality management costs may extend for periods in excess of 100 years. Our provision for these expenditures was $454 million as at December 31, 2018. In 2018, the decommissioning and restoration provision was calculated using nominal discount rates between 6.49% and 7.99%. We also used an inflation rate of 2.00% in our cash flow estimates. The decommissioning and restoration provision includes $249 million (2017 – $270 million) in respect of closed operations.
