Will the Balzac Power Station continue to operate?
The Balzac Power Station and related infrastructure will remain operational for the foreseeable future.

What is the overall timeline of the Balzac abandonment and reclamation project?
Plant demolition began in mid-2013 and and is now complete. Plant site remediation began in 2014 and will take a number of years.

When did the stacks come down?
The stacks were among the final pieces of equipment to be dismantled and removed. This was completed in Q4 2014.

Why are there still remaining buildings at the site?
Current buildings are being utilized during reclamation and remediation activities. All remaining onsite infrastructure will be assessed for future use in upcoming years.

Are all your wells in the area going to be abandoned?
Of the approximately 90 wells in the area, approximately 74 were abandoned — the remainder will continue to produce gas. Operatorship of these existing wells was transferred in 2011 and the wells were diverted to a new facility.  Abandonment of the wells that were not diverted began in 2012. Urban wells, which are those within Calgary city limits, and wells with high sour gas content were a priority and have been abandoned. All wells in scope to be abandoned will be complete by the end of 2017.

What are your plans for diverting natural gas from the wells that will continue to produce?
An established network of pipelines was tied into a new, third-party operated compressor station located at 13-16-27-27W4. The new station moves gas through the system to the East Crossfield Plant, also operated by a third party.

Will the pipelines remain active?
All pipelines in the Balzac gas gathering system were cleaned and purged to place them into a safe state. Some were used for diversion (as above). Pipelines identified with no future use will be abandoned in compliance with applicable regulations. Remaining pipelines may be used for sweet gas, pending new plays and development opportunities.

If you convert to sweet gas will this reduce the setbacks? What would the expected date be?
Nexen has reduced all Nexen-operated Level 2 and 3 sour gas pipelines in the Balzac area to an Alberta Energy Regulator (AER) Level 1 status. This has reduced the pipeline setbacks. For information on setbacks please refer to the AER website EnerFAQs

What will the end use of the property look like?
The final land use of the plant site has not yet been determined. Options are currently being evaluated with stakeholder input and will be communicated when available.

What will happen to McDonald Lake?
McDonald Lake is a water body under provincial jurisdiction. Nexen does not own it and does not control its future. However, as McDonald Lake is an evaporative prairie lake, neither fed or drained by a creek, and is occasionally dry during the summer; it is unlikely to become a classic recreational lake.

Nexen releases treated runoff to McDonald Lake according to our Alberta Environment Approval to Operate. While much of the area runoff from surrounding development and other parties bordering the lake ends up in McDonald Lake, Nexen is the only company monitoring and reporting results to the regulator.

Should I no longer be concerned about sour gas?
Even though the risks associated with sour gas will be greatly reduced, they will not be eliminated as some slightly sour wells will remain operational. Caution should always be taken when in the proximity of oil and gas operations.

Will the traffic volumes change?
It is expected traffic volumes will fluctuate throughout this project’s life cycle. Nexen will take measures to ensure public safety and adhere to school bus schedules.

How will you manage dust control?
Nexen encourages slow speeds on access roads and watering will be implemented on major activity in close proximity to residents.

What are your plans for Nexen’s Balzac area land base?
Nexen is currently focused on an abandonment and reclamation program associated with the Balzac gas plant and related infrastructure. Decisions regarding end land use/commercial opportunities associated with the plant site and/or offsetting lands will be made in the next couple of years.
