Observations:
Foothills Pipelines Ltd (Foothills) provided a site specific orientation and completed Job Safety Analysis. Sign in and out procedures were in place. NEB inspectors observed that signs with the company name, emergency phone number, signage warning of hazards and PPE requirements, and non-smoking signs were posted at the site main entrance. The compressor station is fenced with several egress gates in addition to the main site access. Egress gates were cleared of snow. The wind sock on site was in good condition and highly visible. There are two compressor buildings with each building housing a compressor unit. One of the unit is electrical and the other is powered by natural gas. The product is non-sour dry natural gas. The compressor building is equipped with gas detection. At 10% of the Lower Explosive Limit (LEL), an alarm is initiated, and the building ventilation is started. At 40% LEL, a station Emergency Shutdown (ESD) is initiated. A station ESD shuts down the compressor units, isolates and blows down the station. The compressor building is also equipped with fire detection. Upon fire detection, a station ESD is initiated and the ventilation is stopped. There were cranes in the compressor buildings and log books were present and filled out. There is an alternate source of power onsite which is capable of operating the ESD system, including closing the station isolation valves and opening the blow down valves during a power loss event. The station is equipped with station ESD push buttons located at several locations on site, including near the site main entrance. There are unit ESD push buttons located outside the compressor unit buildings. A unit ESD shuts down the compressor unit, isolates and blows down the unit. The electrical room had warning signs for high voltage and labels warning of electrical shock and arc flash hazards were present on the electrical panels. The building was clean and free of obstructions. Piping was color coded and labelled with arrows for the direction of flow. Foothills explained that fire extinguishers, first aid kits, eye wash stations and bottles are inspected on a monthly basis by their staff. Exits were marked and emergency lighting was present. Battery room had signage warning of the hazards and batteries were shielded with plexiglass. Overall, site was clean and well maintained. No clutter was observed and signage was omnipresent to warn of the hazards. Tools observed had proper guards and were properly secured.
