Welcome Waste Management Facility


About the Welcome Waste Management Facility

The Welcome Waste Management Facility is located in the Municipality of Port Hope, south of Highway 401 between Brand Road and Baulch Road. It contains approximately 450,000 cubic metres of historic low-level radioactive waste, from Eldorado’s former radium and uranium refining operations in Port Hope, that was placed at the facility from 1944 until its closure in 1955.

In October 2009, Canadian Nuclear Laboratories (CNL) - formerly Atomic Energy of Canada Limited (AECL) - the lead agency undertaking the Port Hope Project, was granted a Waste Nuclear Substance Licence by the Canadian Nuclear Safety Commission (CNSC). This permitted CNL to assume responsibility for the Welcome facility on March 31, 2010. The facility had previously been operated by Cameco Corporation under a licence from the CNSC. At the same time, the Government of Canada acquired the 50-hectare property from Cameco.

The Welcome Waste Management Facility lands are the site of the future Port Hope long-term low-level radioactive waste management facility.

Current Facility Operations

CNL is responsible under licence to the CNSC to manage the facility safely, including management of groundwater and surface water at the site that, once treated, is discharged to Lake Ontario via pipeline. AECL must ensure this treated water (effluent) meets CNSC regulatory requirements.

CNL’s responsibilities for the Welcome facility also include:

  • Operation of treatment ponds and effluent discharge;
  • Oversight of on-site environmental monitoring activities;
  • Oversight of well water monitoring in the immediate vicinity of the site;
  • Enhancement of security and other operational systems; and
  • Regular reporting to the CNSC
