Observation 3 - General Observations - North Westover Pump Station
Date & time of visit: 2018-06-05 13:15
NEB Inspectors observed signs with the company name, emergency phone numbers, and non-smoking signs were posted at the site main entrance. The pump station is fenced with egress gates in addition to the main site access. The pump building houses two pump units for Line 9. The pump building is equipped with gas detection. At 20% of the Lower Explosive Limit (LEL), an alarm is initiated and the building ventilation is started. At 40% LEL, the two pump units are shut-down, the ventilation is stopped and the station is isolated. The pump building is also equipped with heat detectors for fire detection. If heat is detected, the two pump units are shut-down, the ventilation is stopped and the station is isolated. There is back-up diesel generator onsite which is capable of operating the ESD system, including closing the station isolation valves and the lighting during a power loss event. The station is equipped with station ESD push buttons located at both ends of the Electrical Switchgear Building (ESB). The ESB had warning signs for high voltage and strobe lights inside and outside to warn of an imminent pump start with a potential for arc flash. Fire extinguishers, first aid kits, eye wash stations and bottles are inspected on a monthly basis. NEB inspectors observed good housekeeping. Station piping had arrows for direction of flow. Valve vaults had confined space warning signs.
Observation 4 - General Observations - Hilton Pump Station

Valve vaults had confined space warning signs.
Observation 5 - CNC - Hilton Station - Pre-Inspections and Logbook for Cranes
The gantry in the pump building did not have a pre-use inspection logbook available. Site staff also indicated that pre-use inspections were not conducted as a matter of practice. This is inconsistent with the company procedure, which requires a pre-use visual inspection of cranes and ancillary equipment prior to each use and to maintain a logbook. This a failure to implement the controls developed by the company for that safe use of the cranes and this is a non-compliance to the NEB OPR s. 6.5 (1)(f).
Log book for documenting pre-use inspections was placed near gantry in the pump building. Email was sent within the company to the appropriate staff to clarify need for log books and use of them for documenting pre-use inspections. The non-compliance was adressed prior to the completion of this report.
Identified non-compliances to company plans or procedures are non-compliances either to:
- the condition of an authorization document that requires the implementation of that plan or procedure; or
- the relevant section of the regulations that requires implementation of that plan or procedure including those sections that require implementation of plans or procedures as a part of a Program
