The policy applies to the handling and storage of a dense non-aqueous phase liquid (DNAPL) for all vulnerable areas where the activity is a significant drinking water threat (existing activity) and in the WHPA-C (future activity).

The handling and storage of a dense non-aqueous phase liquid (DNAPL) may only occur in accordance with an approved Risk Management Plan where the total quantity of liquid product(s) is greater than 25 litres and contains any amount of any of the following:

• Dioxane-1,4
• Polycyclic Aromatic Hydrocarbons (PAHs)
• Tetrachloroethylene (PCE)
• Trichloroethylene or another DNAPL that could degrade to Trichloroethylene
• Vinyl chloride or another DNAPL that could degrade to vinyl chloride.

Establishment of a Risk Management Plan is required. Therefore, the handling and storage of a dense non-aqueous phase liquid (DNAPL) is designated for the purposes of s.58 of the Clean Water Act.
