Over 60 Nova Scotia Power and contractor personnel are working diligently on cleanup efforts following an
oil release yesterday (THURSDAY) at its Tufts Cove Generating Station.

The leak was discovered in an exterior pipe that runs from the onsite storage tanks into the facility by staff during a
routine inspection.

Plant staff immediately activated environmental response protocols by stopping oil flow through the
pipe to prevent further leakage, deploying a boom in the area of the water nearest to the leak, and alerting the company’s environmental services contractors.

Work last night and this morning included the installation of two additional booms in Halifax Harbour in front of the plant as a precaution to contain the oil. Vacuum trucks and oil absorbent materials (pom poms) are being used to remove the oil from the water surface.

Additionally, workers are actively assessing the water and shoreline in the area by helicopter and by boat to prioritize areas requiring cleanup.

The focus for today is to ensure that the oil is contained along the shoreline adjacent to the plant. Cleanup operations
have already begun in known affected areas.

The company has launched an internal investigation of the incident, whichwill include a comprehensive root cause analysis to ensure this type of incident does not occur again.

Nova Scotia Power and its contractor will continue to implement environmental response and monitoring protocols until
all of the leaked oil has been cleaned up, including the water in the inlet, shoreline area and soil.

Response efforts are proceeding as quickly as possible keeping in mind the safety of all involved in the containment activities.

Nova Scotia Power takes its environmental commitments very seriously. Each plant has a detailed response plan in place to minimize the environmental impact of such situations and provide operational protocols to safely and quickly address
the issue.
