Base Plant Oil Sands Mining & Processing Plant
Lewis Commercial SAGD Project
The Alberta Energy Regulator (AER) has received OSCA Applications No. 1962328 and 1962317, and EPEA Applications No. 089-00000094 and 002-00392715, submitted by Suncor Energy Inc. (Suncor). These four applications were submitted as two integrated application packages: one proposing amendments to Suncor’s Base Plant OSCA and EPEA approvals, and the other proposing amendments to Suncor’s Lewis Commercial SAGD Project OSCA and EPEA approvals. The AER is currently reviewing the applications.
This notice sets out the deadline for filing a statement of concern under the section How to File a Statement of Concern.
Description of the Applications
To be known as the Base Plant-Lewis Project, Suncor has applied under the OSCA and EPEA to integrate the Lewis Commercial SAGD Project with the Base Plant oil sands processing plant. Fluids from the initial Lewis SAGD well pads will be processed using existing infrastructure at Base Plant. Steam for the initial Lewis SAGD well pads will also be generated at Base Plant.
New assets and infrastructure required for the project include a new Lewis Project field terminal, a new water treatment facility at Base Plant, a new natural gas supply line, and portions of an intersite multi-use corridor containing a disposal pipeline, power line, access road, steam transmission pipelines, and an emulsion pipeline. Suncor is also proposing amendments to the locations and arrangement of the initial well pads, gathering pipelines, and supporting infrastructure at the Lewis Commercial SAGD Project. The subject applications do not include portions of the intersite multi-use corridor that are located outside the approved Base Plant and Lewis Project areas and will be the subject of future regulatory applications.
The Lewis Commercial SAGD Project is currently approved for four phases of 40,000 barrels per day (bpd) each and represented by four central processing facilities (CPFs). The proposed Base Plant-Lewis Project amendments removes two phases with two CPFs (80,000 bpd total) of processing capacity at the Lewis Commercial SAGD Project by leveraging available capacity within existing Base Plant processing infrastructure. The project would support continued bitumen production beyond the life of mining operations.
