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. In December 2007, the Alton Underground Gas Storage facility achieved approval and in May 2013, the Alton Gas Pipeline achieved approval. More information on the Environmental Assessment processes for each can be viewed here:

Additional approvals are required before operations can commence.
