Alton Natural Gas Storage reaches an agreement with Nova Scotia Environment to apply for Alton's Industrial Permit in two phases. The two phases were necessary to streamline the approval process to allow for the removal of trees over the water pipeline route and cavern facility site. In order to meet the environmental approval conditions and remain on target with the project schedule, the right of way was cleared in April 2008. Option Easement Agreements were acquired for this same right of way.

- August - Alton Natural Gas Storage announces that due to current adverse market conditions in the capital markets, the project would not be moving forward as scheduled.
- Throughout 2008 - Preparations continue for an Environmental Assessment of the natural gas pipeline necessary to connect the storage facility to the existing natural gas pipeline located approximately 10 km away from the Alton Natural Gas Storage project site. Preliminary route selection is finalized, a constructability review is conducted and bird and vegetation studies are completed. Geotechnical work for the cavern site, the water pipeline route and the river site were completed. The pre-engineering and pre-construction surveying is completed.
- August - Alton Natural Gas Storage acquires land at the cavern and river sites for the purpose of constructing the water handling facilities and natural gas storage facilities. The back access roads to the cavern site are developed and the first drill pad is constructed.
- November - Additional studies are initiated as part of the environmental approval conditions. These include fish and fish habitat-monitoring programs at the river intake site. The research programs are ongoing and conducted in conjunction with Dalhousie University's Agricultural Campus in Bible Hill and Nova Scotia Agricultural College's Department of Plant & Animal Sciences.
Alton Natural Gas Storage commences discussions with potential storage customers.
- April - Alton Natural Gas Storage announces the permit area has been determined to be suitable for the storage of natural gas. RESPEC Consulting and Services of Rapid City, South Dakota, conducts a detailed geomechanical feasibility study to confirm the structural stability of the cavern design through salt and rock core testing and computer modeling.
- July - Alton Natural Gas Storage registers the underground hydrocarbon storage facility project for Environmental Assessment in accordance with Part IV of the Nova Scotia Environment Act as a Class 1 Undertaking. The Honourable David M. Morse, Minister of Natural Resources, approves the use of the geological formation for the development of a storage reservoir.
- November - Alton completes a 3D seismic program over the Alton Natural Gas Storage site. Alton Natural Gas Storage receives a Hydrocarbon Storage-area Licence from the Minister of Nova Scotia Department of Energy. Alton Natural Gas Storage registers its Supplemental Information to the Alton Natural Gas Storage project EA in accordance with Part IV of the Nova Scotia Environment Act.
- December - Alton Natural Gas Storage receives Environmental Assessment approval from the Nova Scotia Minister of Environment to proceed with the development of the brining facilities.
- February - Alton Natural Gas Storage completes the interpretation of the 28 km of new 2D seismic data acquired in November 2005.
- June - Alton Natural Gas Storage completes the drilling of a core hole in the Alton Licence area. During the third quarter of 2006, the core hole drilling report is completed and the geotechnical analysis begins.
- December - Alton Natural Gas Storage files an application for a Hydrocarbon Storage-Area Licence.
Start of ongoing public and stakeholder consultations, related to gravity and seismic surveys.
- February - Alton Natural Gas Storage acquires seismic data covering part of the Alton underground natural gas storage area. The seismic data confirms a suitable salt formation.
- July - Alton Natural Gas Storage completes gravity surveys over the licence area. Gravity surveys assist in identifying areas of salt formation build up (thickening) which is required for the development of underground natural gas storage cavern facilities. The gravity surveys were correlated with existing seismic data and confirm an anomalously thick salt formation.
- October - Announced the commencement of a 28 km, 2D seismic program on the Alton Natural Gas Storage project area.
- November - 28 km seismic survey is completed, further defining the dimensions of the salt formation. Alton Natural Gas Storage LP is created.
