Sweet gas plants follow the conservation and reclamation process set up for Upstream Oil and Gas.
Note: Sulphur storage facilities (with storage capacity of greater than 100 tonnes), brine storage ponds (greater than 5000 milligrams per litre of chlorides), and bulk petroleum storage facilities (with storage capacity of at least 10 000 cubic metres) associated with energy development activities also require an EPEA approval in order to construct, operate, and reclaim. Requirements for conservation and reclamation follow the same process as sour gas plants.
When a sour gas plant ceases operation, the approval holder must apply for an amendment to its EPEA approval for decommissioning and reclamation. The terms and conditions of an amended EPEA approval provide further site-specific requirements for decommissioning and reclaiming.
When reclamation is complete and all the terms and conditions of the EPEA approval have been met, including achieving the approved reclamation outcome, the approval holder must apply for a reclamation certificate from the AER.
Reclamation should be conducted in a timely manner to minimize environmental and fiscal liabilities. The AER recommends that operators start decommissioning and reclamation activities for an area immediately after operations have ceased or when the disturbed land is no longer required for operations.
For further information on the reclamation certificate application process for enhanced recovery in situ oil sands or heavy oil processing plants and oil production sites see the application content requirements and the frequently asked questions for EPEA-approved facilities.
