NSUARB approved Nova Scotia Power's $454,604 unforeseen and unbudgeted work order for removal of deteriorated frost casing on the Gulch Surge Tank at the Bear River Hydro System.
AI summary
- Nova Scotia Power Incorporated submitted a U&U work order (CI# 39844) on July 30, 2010, requesting Board approval for $454,604 to remove a deteriorated timber frost casing on the Gulch Surge Tank at the Annapolis Tidal Generation Station Bear River Hydro System and install a compressor and air bubbler system to prevent future freezing.
- The justification was classified under Health & Safety / Maintenance: inspection in early 2010 found the timber casing detaching from the main structure, posing a falling-debris risk to the penstock below and a safety hazard requiring immediate mitigation (Work Order, Capital Item Justification section).
- The project was accelerated from a planned 2011 ACE inclusion after the casing deteriorated faster than anticipated; access around the tank was cordoned off pending remediation (Work Order, Capital Item Justification section).
- Competitive proposals were received from two firms; the chosen approach—frost casing removal and installation of a bubbler system—was described as the standard NSPI method for surge tank upgrades and the least-cost alternative with low expected future maintenance (Work Order, Proposal Evaluation section).
- The Nova Scotia Utility And Review Board issued its approval letter on August 19, 2010, confirming authorization of the full $454,604 amount (Board Decision Letter, Doc. No. 180224).
