In December 2011, the Wek’èezhìi Land and Water Board (WLWB) and the Mackenzie Valley Land and Water Board (MVLWB) hosted “An Introduction to Risk Assessment”, which was a 2-day information session on human health and ecological risk assessment. The purpose of the information session was two-fold: to ensure that all parties participating in Board decisions involving risk assessments in the mining industry have a good understanding of the topic, and to promote an open discussion about risk assessment.

The Mackenzie Valley Land and Water Boards, in collaboration with the Government of the Northwest Territories, are pleased to make available updated municipal plan templates. These fillable-pdf documents were collaboratively designed to be user-friendly and are intended to reduce the workload of municipalities to satisfy their municipal licence requirements. The templates include:

Sewage Disposal Facilities (SDF) (2018)
Solid Waste Disposal Facilities (SWDF) (2018)
Water Treatment Plant (WTP) (2018)
Spill Contingency Plan (2018)

The templates are now available for download on the Resources for Municipalities page of all Land and Water Board websites.

*These templates are not meant to replace already existing Operation and Maintenance Plans that municipalities have completed.
