153B: Owner must notify regional authority of dangerous dam
or “If you think your dam might be dangerous, you must tell the local authorities right away.”

You could also call this:

“Regional authorities can take action to protect people from unsafe dams.”

If a regional authority thinks a dam is dangerous, they can do a few things to keep people safe. They can put up a fence to stop people from getting too close to the dam. They can also put up a sign near the dam to warn people not to go near it.

The regional authority can also tell the dam owner to fix the dangerous parts of the dam. They will give the owner a written notice that says what work needs to be done and when it needs to be finished. The owner will have at least 10 days to do this work after they get the notice.

If someone doesn’t do the work that the regional authority tells them to do, they are breaking the law. This is called an offence. If a person does this, they can be punished. If it’s just one person, they might have to pay up to $300,000. If it’s a company, they might have to pay up to $1,500,000.
