Power plants in Ontario are subject to regulation by the Technical Standards and Safety Authority (TSSA) in accordance with Ontario Regulation 219/01: Operating Engineers (Ontario.ca).
O. Reg 219/01 applies by default. However, under the Alternate Rules, registered plant owners and users can opt to receive authorization from TSSA to operate under an alternate safety path.
These Alternate Rules came into effect on October 2, 2020, when the then-Minister of Government and Consumer Services (now Minister of Public and Business Service Delivery) approved them to aid the efficient and flexible administration of technical standards under O. Reg 219/01.
These alternate rules facilitate a risk-based approach to industry regulation, and affect certain requirements in O. Reg 219/01, including plant staffing, certification time requirements, and electronic logbook requirements.
There are now three safety paths which TSSA regulates and monitor for safety compliance:
In other words, plants may continue following the existing O. Reg 219/01 or choose to follow alternate rules.
Additional Alternate Rules also offer Operating Engineers alternative methods of meeting their certification requirements.
Path 1 measures the size, complexity, and safety risk of many factors in addition to a plant’s power rating, such as:
These factors are used to calculate a risk rating for the plant, which is then used to determine appropriate staffing requirements (subject to the Chief Officer’s right to adjust the plant staffing requirements as necessary).
Path 1 plants are subject to regular TSSA inspections.
Path 2 of the alternate rules requires plant owners and users to customize a site-specific Risk and Safety Management Plans for TSSA review.
The plan must be signed by a professional engineer and a senior person responsible for site safety.
The plan must provide evidence to support the plant’s ability to maintain safety, based on an acceptable risk level.
If the plant’s Risk and Safety Management Plan (RSMP) is approved by TSSA, the plant must maintain safety compliance records for review by TSSA.
Path 2 plants are subject to regular TSSA inspections and audits of RSMP-related documents and records.
Alternate rules offer Operating Engineers alternative methods of meeting their certification requirements.
