Description

The McLeod River headwaters originate in the Rocky Mountains in west-central Alberta and join the Athabasca River near Whitecourt. Coal mining has occurred in the McLeod watershed since the 1970s and more recently, there has been both reclamation and expansion of mine sites in the upper basin. In this study, trends in surface water quality parameters in the McLeod River watershed were assessed over time to understand changes in water quality and associations with active mining and reclamation activity.

Description

This guide addresses those areas where supplementary guidance on reclamation and regulatory closure for powerline right-of-ways is required. This includes: transmission line right-of-ways on both private land and public land, and distribution line right-of-ways on public land. The practices and criteria presented in this document are for use by powerline operators and qualified environmental professionals when removing powerlines, and for assessing powerline right-of-ways and associated lands.
