Observation 2 - Toronto Terminal - Fire system
Multiple portable fire extinguishers were available at the facility and were current on their monthly inspection requirements. TNPI stated that inspection and tests of the fire suppression system are conducted annually by an external 3rd party and provided documentation of the most recent inspection (2019). The results indicate that the system was tested in accordance to NFPA 25 requirements and deemed functional. Elements of the system tested included (but not limited to)

Observation 3 - Process Hazards and Management of Change - TNPI system
Discipline: Management System
TNPI presented a copy of the Process Hazard Analysis Hazard Operability Study performed in 2017 on the TNPI East system which identifies potential hazardous events and scenarios, the level of risk, mitigations and recommendations to address such hazards. Company representatives stated that the recommendations are in progress, and follow a risk based approach with all high risk items being already completed. The company presented and also stated that action items for the study are tracked through its internal system with assigned responsibilities and expected dates of completion. It also stated that it will revalidate the study in 2022 as part of a 5 year cycle.In assessing implementation of recommendations from the study, the Management of Change (MOC) for the increase of Pressure Relief Valve (PRV) pressure set points and modifications of Surge Relief Valves (SRV) as part of the over pressure protection project was presented and reviewed. The MOC identified stages of initiation, pre-approvals, evaluation and analysis (inclusive of performing risk assessments, stakeholder communication, implementation plan and approval), implementation and follow-ups for each proposed change, tasks and action items assigned to responsible personnel, and metrics to track overdue action items.

Observation 4 - Toronto Terminal - Inspection, Measurement and Maintenance
Discipline: Integrity Management
TNPI stated that its maintenance program for equipment, including mechanical, electrical and instrumentation system is maintained in its CMMS database. The maintenance for such equipment is frequency driven (e.g., monthly, semi-annually, annually) with the system providing notifications of when any inspection, testing and calibrations need to be undertaken with resulting work orders created in order to complete the tasks.
Notifications for overdue items which may result in a backlog are sent to supervisors and managers. The company also stated that backlogs for maintenance actions are prioritized for completion based on supervisory judgement but it is currently developing a risk based prioritization system to address such backlogs. Further, deferrals are subject to an MOC process that require management approval and sign-off which is also tracked electronically via an internal database (IFS).
Sample records of recent monthly routine tank inspections were presented and reviewed and indicate that such inspections remain current. These inspections assess the condition of the tank foundation, shell, roof and appurtenances such as valves, piping, sample points, access points, dike etc. and check for items such as distortions, signs of product leakage, paint condition, corrosion, etc.
Company presented sample work order records of instrumentation calibrations which are performed either annually or semi-annually. The records indicated actions were completed with the exception of differential pressure level transmitter for which action needs to be undertaken and is currently being tracked.
Company presented sample records of the most recent annual pressure relief device testing (primarily pop-test) and certification which appeared complete and with resolution of test findings where repairs were required.
Observation 5 - Integrity Dig
Integrity dig performed on the NPS 10 TNPI mainline based on results from recent In-line inspections (ILI). Company representatives stated due to the corrosion feature identified from the ILI and validated by the dig, a compression sleeve was installed as the repair method and the pipe was re-coated with a KEMA tape coating and bitumen based primer and that the coating was wrapped with a 55% overlap. Company also stated that NDE in the form of phased array ultrasonic tests and magnetic particle inspections were performed on the pipe.Company representatives stated that the safe excavation pressure for the pipe as the work was performed was 600 psi vs. a normal operating pressure of 650 psi. Records were presented to demonstrate the daily communication with the control center with respect to recording the safe excavation pressure prior to commencing work, the nature of work being undertaken on the pipeline and persons present at the worksite. It was also stated that due to the potential for induced current and resulting arc flash to occur as the work is being undertaken near overhead powerlines, valves and exposed steel are tested for voltage readings over the course of the work activities.
Observation 6 - Castleton & Bowmanville Pump Stations
TNPI stated that the stations are remotely monitored from the TNPI control room but inspections performed by maintenance personnel on a 10 day frequency to check the condition of the fencing, piping, station equipment and signs of loss of containment.Emergency back-up generator was present in each station and serve to isolate the stations by closing the station inlet and outlet block valves as well as the pump suction and discharge valves in the event of a power failure. The work orders and records of the most recent (2020) annual preventative maintenance (PM) performed on the generator (Castleton) presented by TNPI indicate that the PM is up to date.TNPI stated it has implemented a process for identifying and tagging equipment deemed as safety critical which are ranked High, Medium or Low. Equipment in the stations was tagged to identify their safety criticality ranking.The stations are equipped with sump tanks and TNPI stated that the tank levels are monitored at the control room via level transmitters and alarms. TNPI also stated that the tanks are inspected on a prescribed frequency of 3 years (for single wall tanks). Work order records presented indicate that inspections for the sump tanks are overdue but MOC have been created for extensions and to complete the tasks within a 30 day period.
Observation 7 - Integrity Dig - IR#2
