Description

The objectives of this review were to describe the river course variation of benthic algal biomass, nutrient and nonfilterable residue variables and their interrelationships in Alberta rivers. Trends in these variables were compared between river basins, and the physiographic zones and ecoregions through which these rivers flowed were also documented.

Description

The guidelines presented herein were developed by Alberta Environment and reviewed jointly by Alberta Environment and The Coal Association of Canada. They apply to all new coal mines that become operational after January 1, 1977 whether the operation entails a completely new mine site, an additional mine, or a major coal process­ing plant expansion on an existing mine site. Permits to construct or licences to operate under The Clean Water Act will be issued provided that the provisions of these guidelines have been considered and adequate waste water management provided to comply with the standards. The extent of compliance required of existing coal mines will be determined on an individual basis depending on circumstances and will be specified in relevant licences or permits.
