Managing Air Emissions

Alberta Environment and Parks (AEP), industry and other stakeholders have developed an electricity emissions management framework, based on recommendations of the Clean Air Strategic Alliance Electricity Project Team.

Emissions Trading Program

The Emission Trading Regulation (Alberta Regulation 33 / 2006) encourages power stations to reduce their nitrogen oxide and sulphur dioxide emissions prior to mandatory improvements required in their Environmental Protection and Enhancement Act (EPEA) industrial approvals.

Mercury Controls

Mercury emission control requirements have been in place at all coal-fired power plants since 2011.

  1. Mercury Emissions from Coal-fired Power Plants Regulation
  2. Canadian Council of Ministers of the Environment (CCME) - Mercury
  3. Summary Report on Canadian and American Legislative and Regulatory Initiatives for the Reduction of Mercury Emissions from Coal-Fired Power Plants

Potential "Hot Spots"

Standards/EPEA Approval Clauses

AEP is actively implementing the new air emission limits standards for nitrogen oxides and sulphur dioxide through the 10-year approvals issued under EPEA. These power plant approvals are comprehensive and cover all environmental requirements an operator must meet.

Existing facility emission limits apply until a unit’s end of design life. After that, Facility operators must then either retrofit to meet the new standards or utilize previously generated emissions credits.

New electricity generating units must meet standards of the day in effect at time of regulatory approval.

Emission Management Framework Review

The Electricity Emission Management Framework, along with the emission standards will be reviewed every five years, to encourage continuous improvement. Links to the results of the two previous reviews are available on the Clean Air Strategic Alliance, Past Projects page:
