a) application of road salt where the impervious surface is greater than 80%
b) storage of road salt where the vulnerability score is 10 and the quantity stored is greater than 5,000 tonnes.

The Risk Management Official shall negotiate or establish a Risk Management Plan with the person engaged in the designated threat activity within three years of the Plan coming into effect. The RMP is to contain, at a minimum, structural or management alterations (if any) which when implemented will ensure that existing operations continue to function in a manner which minimizes the risk to sources of municipal drinking water. Risk Management Plans are expected to be based on existing programs such as ""Smart About Salt ; for commercial properties and the ""Synthesis of Best Management Practices ; for municipal properties.
