Underground natural gas storage is highly regulated and requires many permits, licenses and approvals from provincial and federal authorities.


Decommissioning

In October 2021, we announced the decision to decommission the Alton Natural Gas Storage Project. We’ve submitted our plan for decommissioning to the Province of Nova Scotia and we’re beginning the process to gather public feedback on our proposed approach.

To provide feedback on the plan, you can:

  • Send an email with your comments to [email protected]. Please share your comments in the text of the email; do not include attachments
  • Send a letter with your comments to:
    Alton Natural Gas Storage, P.O. Box 70, Stewiacke, NS, B0N 2J0

Please include your name, address and phone number with your submission. See submission fact sheet for additional information.

The deadline to submit comments is by end of day Tuesday, January 25, 2022.

Environmental Assessments

Following extensive studies and consultation, Nova Scotia Environment issued two Environmental Assessment (EA) approvals for the Alton project.


Industrial Approval

On January 21, 2016 the Government of Nova Scotia announced regulatory approvals for Alton Natural Gas Storage, including an industrial approval (IA) to operate the brine storage pond. On April 8, 2019, the Government of Nova Scotia issued an amended approval with additional conditions to operate at the river site. The issuance of the IA was appealed to the Nova Scotia Supreme Court by Sipekne’katik First Nation. A Court decision on March 24, 2020 set aside the IA and ordered an additional 120 days of Crown consultation between the Province of Nova Scotia and Sipekne’katik First Nation. Alton is abiding by the Court decision and only care and maintenance activities will take place at the river site during this period. Alton will also continue to comply with any direction by the Nova Scotia Department of the Environment during this period.


Nova Scotia Utility and Review Board

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. On March 11, 2019 the UARB released its decision on the application, granting the extension request.


New Regulation

Environment and Climate Change Canada indicates that a federal regulation under the Fisheries Act is being developed to regulate brine release at the Alton project into the tidal Shubenacadie River estuary.

The development of the regulation means the Alton project will be subject to further compliance and enforcement provisions in addition to regulatory oversight by Nova Scotia Environment and the federal Department of Fisheries and Oceans. A draft of the regulation is expected to be published in Canada Gazette, Part 1 in 2020, followed by a public comment period.
