The Alberta Energy Regulator (AER) has received Oil Sands Conservation Act (OSCA) application 1949850 and Environmental Protection and Enhancement Act (EPEA) application 022-00206355 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 Sunrise Thermal Project is located in Township 95 Range 7, West of the 4th Meridian (W4M). The project utilizes Steam-Assisted Gravity Drainage (SAGD) technology to recover bitumen from the Wabiskaw-McMurray Deposit. The facility includes central processing facilities (CPFs), SAGD well pairs, and supporting infrastructure and pipelines. The project operates 74 injector wells and 92 producer wells across 12 well pads within Development Area 1 (DA1) and Development Area 2 (DA2). 

Cenovus has applied to amend OSCA Approval No. 10419YY and EPEA Approval No.206355 to construct and operate a proposed Casing Gas Cooling and Separation Facility at the existing CPF. The proposed Casing Gas Cooling and Separation Facility will support production associated with all future development, beginning with approved development in DA2 and DA3. In addition, an inlet degasser is proposed to manage the increased dissolved vapour flow rates due to Electric Submersible Pumps (ESPs) production.
