The development and operation of an underground natural gas storage facility is highly regulated and requires many permits, licenses and approvals. Alton Natural Gas Storage has received all environmental and regulatory approvals to proceed with development.
Following extensive studies and consultation, Nova Scotia Environment issued two Environmental Assessment (EA) approvals for the project:
- Alton Underground Natural Gas Storage (approved in December 2007)
- Alton Gas Pipeline (approved in May 2013)
On January 21, 2016 the Government of Nova Scotia announced regulatory approvals for Alton Natural Gas Storage, including an industrial approval to operate the brine storage pond. Following thorough scientific assessment and extensive consultation, government determined the project is safe for the environment. On April 8, 2019, the Government of Nova Scotia issued an amended approval.
On November 14, 2018, Alton applied to the Nova Scotia Utility and Review Board (UARB) for an extension to the Approval to Construct the natural gas storage caverns to 2023. There are no changes proposed to the facility authorized by the Approval to Construct and we do not seek any change or modification to the terms and conditions in the Approval to Construct, other than the date. The request for the extension is here, and can be accessed on the Nova Scotia Utility and Review Board website database as matter number M08974. For supporting materials on the Approval to Construct, go to the database and enter matter number M04172.
As part of the review process for the extension request, the public submitted letters of comment. View Alton’s response to the letters of comment.
On March 11, 2019 the UARB released its decision on the application, deciding to grant the extension request.
