Welcome to
Atlantic RBCA

Atlantic Risk-Based Corrective Action (Atlantic RBCA) is a process to assess and manage the remediation of sites impacted by petroleum hydrocarbons and other contaminants in Atlantic Canada. The implementation and maintenance of Atlantic RBCA is overseen by the Atlantic Partnership in Risk-Based Corrective Action Implementation (Atlantic PIRI).

Established in 1997, Atlantic PIRI is a collaborative group of provincial environment regulators, industry representatives, and regional environmental consultants from Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador. This group identifies and discusses issues, develops standards and processes, and provides recommendations for continued technical and regulatory harmonization across the region.

Since 1997, the Atlantic RBCA Toolkit has  been used to successfully assess or remediate petroleum-impacted sites and facilitate regulatory file closures for more than 8,279 sites in the region, making these properties ready for brownfield redevelopment opportunities.
