Ontario is strengthening the regulation of vertical closed loop drilling for geothermal energy systems, with new rules that take effect immediately.

The province is requiring geothermal installers to:

• Obtain provincial approval for vertical closed loop geothermal systems
• Consult with a certified geoscientist or engineer before drilling
• Develop an emergency plan before drilling

The Ministry of the Environment will consult with industry stakeholders in the coming months on the new regulations.  The ministry will also be conducting inspections to ensure installers are meeting safety standards.
