Plains Midstream Canada ULC …

Plains Midstream Canada ULC (“Plains”) is pleased to provide comments on the Ministry of Environment, Conservation and Parks (the Ministry) proposed changes to the On-Site and Excess Soil Management Regulation (the Regulation). Over the public comment period announced by the Ministry, Plains has engaged relevant internal stakeholders to review the updated regulatory processes that will impact the company and its assets.

Plains appreciates the effort made by the Ministry to conduct a comprehensive review of the Regulation and the feedback provided from interested parties in developing these changes. Plains provides the following comments on the Ministry’s proposed changes:

• Plains is supportive of the proposed amendments and removing barriers to the re-use of these low risk soils. Regarding salt-impacted soils, Plains would prefer the option to either re-use these soils or to continue to direct this material for landfill disposal. This option allows for greater flexibility in soil management processes.

Plains supports the development, review, and update of compliance requirements, as well as service standards or other guidance provided by the Ministry. Properly designed, documents such as these enhance regulatory process clarity, predictability, and timing certainty. Please consider the comments and suggestions raised by Plains and its various stakeholders when undergoing the final review of the Regulation.
