Links to CASA

The Clean Air Strategic Alliance (CASA) provides the framework within which the Palliser Airshed Society (PAS) and other airshed zones operate. CASA is a provincial alliance formed to provide the strategic management of air quality in Alberta, with senior representatives from government, industry, and non-government organizations. It operates by consensus but is directly accountable to the Ministers of Environment, Resource Development, and Health and Wellness. CASA stakeholders work together to develop practical and innovative responses to air quality issues. Air Quality Management within airsheds is one such approach.

The Regional, airshed approach works well for problems that are regional in nature and allows those within a region to work together to resole air quality issues. The CASA document, "Zone Air Quality Management Guidelines" sets out the vision and principles of the Alliance under which airshed zones operate. Airshed zones follow the CASA model of consensus decision-making, in which stakeholders try to resolve their concerns in a collaborative manner. CASA also invites representative from the PAS and other airshed zones to join in CASA projects and working groups, where appropriate.

The PAS also shares experience with other regional airshed management zones, as they establish their management plans and develop their programs.

This zone, that encompasses the Medicine Hat/Redcliff region, joins the Fort Air Partnership, the Peace Airshed Zone Association, the Parkland Airshed Management Zone, the Strathcona Industrial Association, the West Central Airshed Society and Wood Buffalo Environmental Association that have been set up in the last few years.
