Saskatchewan’s rules are clear: prevent releases, report incidents immediately, and remediate to provincial standards. Here’s a concise breakdown of the legislation, reporting lines, and cleanup obligations that matter to operators in various sectors across the province.
This is the final part of our series on Western Canadian environmental regulations for hazardous materials and spills.
Core Environmental Legislation in Saskatchewan
Below, we list the governing systems for managing hazardous material storage and release in the province. Consulting these legal acts, codes, and frameworks is a good place to start when operating new facilities in Saskatchewan or addressing a disaster.
Environmental Management and Protection Act, 2010 (EMPA) & Environmental Code
EMPA is the foundation for pollution prevention, spill duties, and enforcement. From this legislation, the Saskatchewan Environmental Code sets results-based requirements, including the Discharge and Discovery Reporting chapter for spills and historical impacts.
Hazardous Substances and Waste Dangerous Goods Regulations (HSWDGR)
These regulations govern the storage and handling of hazardous substances and waste dangerous goods. The Ministry of Environment must approve the construction, operation, modification, and decommissioning of storage facilities.
Sector-Specific Regulations for Oil & Gas
Upstream operations (wells, facilities, pipelines, flowlines) are regulated by the Ministry of Energy and Resources (MER), with detailed incident definitions and reporting mechanics set out in Directive PNG014.
Reporting Spills and Releases: What to do Immediately
- Call the provincial spill line: report any spill/release or emergency that may harm the environment or public health immediately to the 24/7 Provincial Spill Control Centre: 1-800-667-7525.
- If it’s upstream oil & gas, also notify MER via the Emergency Support Line: 1-844-764-3637, then follow MER’s incident categories and timelines (PNG014). Non-members of an Area Spill Response Unit must have equivalent equipment and an approved spill response plan.
- Submit the 30-day written report after the emergency phase is complete.
- Report discoveries of historical contamination (e.g., when soil impacts are found during construction) under the Environmental Code’s Discharge and Discovery Reporting chapter.
Immediate on-site actions: stop the release if safe, protect workers/public, contain with appropriate measures, and document volumes, media affected, and initial controls.
Remediation and Closure Expectations
After stabilization, delineate impacts via soil, groundwater, and surface-water sampling. Cleanup must meet Saskatchewan Environmental Quality Guidelines (SEQG) or other accepted criteria referenced by the ministry.
Use the province’s SEQG and impacted-site process to plan and verify remediation, then submit closure documentation as required. (Note: SEQG updates took effect in 2024; use current values or provide justification if using previous values per project context.)
Storage, Handling, and Waste Management
In Saskatchewan, storage and waste-handling obligations under EMPA and the HSWDGR are prescriptive: approvals, engineering controls, and documentation must be in place before materials arrive on site. The goal is straightforward: prevent releases, track hazardous substances cradle-to-grave, and demonstrate due diligence during inspections.
- Obtain approvals to construct, operate, modify, or decommission hazardous-substance and waste-dangerous-goods storage facilities. Maintain secondary containment and compatible, serviceable tanks/containers.
- Manage hazardous substances/wastes in line with HSWDGR requirements (classification, safe storage/handling). Coordinate transportation with applicable dangerous-goods rules and provincial expectations.
A Practical Compliance Checklist from Our Experts
- Post the 1-800-667-7525 (provincial) and 1-844-764-3637 (MER oil & gas) numbers and train staff on when/how to call.
- Keep an up-to-date Emergency Response Plan; if not in an Area Spill Response Unit, maintain equivalent equipment and an approved plan.
- Register and maintain approvals for storage facilities; inspect tanks, piping, and containment on a defined schedule.
- Use current SEQG values when setting remedial objectives; document rationale if using previous values.
- Align incident reporting with Directive PNG014 categories and timelines.
