A drinking water threat activity that resumes after an interruption or expands after the date the Source Protection Plan takes effect is considered existing and is subject to policies addressing existing activities when:

It is usually occurring on the property but has been interrupted for a maximum of 24 months due to temporary circumstances such as fire, renovation, change of ownership or due to the seasonal nature of the activity
It involves an expansion of an existing activity but the expanded activity would be more protective of drinking water sources
It involves an expansion of the existing physical space but does not result in an expansion of the existing activity (unless the expansion of the activity is more protective of drinking water sources)
It involves an expansion of the existing activity that is minor such that:

it does not require regulatory or planning approvals; and
it is not part of, or was not preceded by, an expansion of the physical space that required regulatory or planning approvals.
