The Alberta Energy Regulator (AER) has received Oil Sands Conservation Act (OSCA) application 1950570 and Environmental Protection and Enhancement Act (EPEA) application 042-00048522 from Cenovus Energy Inc. 

This notice also sets out the deadline for filing statements of concern on both applications. See the section below on how to file a statement of concern and for the filing date.

Description of the Applications
The Christina Lake Thermal Project is located in in Townships 75 and 76, Ranges 4, 5 and 6, West of the 4th Meridian (W4M). The project utilizes Steam-Assisted Gravity Drainage (SAGD) technology to extract bitumen from the Wabiskaw-McMurray Deposit. The facility includes central processing facilities (CPFs), SAGD well pairs, and supporting infrastructure and pipelines. 

Cenovus has applied to amend OSCA Approval No. 8591 and EPEA Approval No. 48522 to update the calendar-quarter SO2 emission limit from 1.32 t/d to 1.65 t/d for scenarios where the sulphur inlet is above 5.0 t/d. Cenovus is also proposing to evaluate the quarterly sulphur recovery and SO2 emission requirements based on the previous calendar quarter’s inlet sulphur rate.
