CNL Continues to Enhance Water Management Mitigation Measures

rainfall

As a result of extreme weather and record rainfall in Northumberland County on June 23, legacy treatment ponds on the site of the Port Hope Project Long-Term Waste Management Facility overflowed, as publicly disclosed on June 25.

Canadian Nuclear Laboratories (CNL) has measured the results of independent analysis of water samples, collected offsite, against the provincial and federal criteria for the protection of aquatic life and has confirmed that the effect of the water overflow on the environment was negligible.

These treatment ponds are part of the old wastewater collection and treatment system constructed circa 1970s, and will be decommissioned and removed as part of the Port Hope Project.

Immediately following the June 23 event, CNL initiated a thorough review of all water management plans and procedures for the site. CNL is taking all actions necessary to enhance its water management plans for both the Port Hope and Port Granby projects to prevent a recurrence.

These actions are in alignment with an order issued on July 7, 2017 by the Canadian Nuclear Safety Commission (CNSC) to CNL related to the June 23 overflow of water on the site of the Port Hope Project facility.
