As part of Suncor Energy (U.S.A.) Inc.’s 2020 settlement agreement with the Colorado Department of Public Health and Environment (CDPHE), we engaged Kearney – an independent, third-party expert – to investigate the root cause of our past emissions exceedances and identify refinery improvement opportunities. Based on these findings and recommendations, we developed an Improvement Plan that highlights what we have done so far and what we plan to do. It has two parts: 1) Implementation Plan for actions required by the settlement agreement with CDPHE; and 2) Voluntary Measures that are additional actions we are taking in response to Kearney’s other recommendations.

CDPHE approved our Implementation Plan on May 20, 2021. The required elements from the plan were completed ahead of schedule in 2022.
