1.1.3 Recollections of the incident in December 2023 One of the PLT during our site assessment explained the incident. He reported that he was called to investigate why the power was decreasing. He saw that the wicket gate controls were tr...

AI summary A PLT investigated a December 2023 incident where turbine power decreased despite wicket gate controls attempting to open. The rpm remained steady, but controls failed to respond, accompanied by grinding noises. The turbine was shut down and found in the same damaged state. Don confirmed these observations.

3.7 Emergency Closure Gates and Valves It is important to understand that the emergency closure itself is not as fast as it may sounds. The only emergency closure mode existent now, is the closure of the wicket gates. The intake butterfly...

AI summary The emergency closure system relies solely on wicket gates, which are not as rapid as perceived. Intake butterfly valves and penstock gates are manually operated without automated controls, highlighting limitations in emergency response mechanisms.

Emergency Preparedness: Review and update emergency response procedures, ensuring that all personnel are trained and ready to respond to emergencies. Verify the functionality of all emergency shutdown systems. Being prepared for emergencie...

AI summary The text emphasizes the importance of reviewing and updating emergency response procedures, ensuring personnel training, and verifying emergency shutdown systems to manage hazards effectively and minimize operational and safety impacts.

4.1.4 PUBLIC SAFETY & SECURITY BEC does not have a formal public safety plan and has not completed a public safety risk assessment. All dams owned by BEC are in publicly accessible areas and the public can regularly interact with the struc...

AI summary BEC lacks a formal public safety plan and has not conducted a public safety risk assessment. Dams are in public areas, exposing visitors to risks such as drowning and falls. The CDA Guidelines recommend completing a risk assessment and developing a public safety plan to mitigate these risks.

4.1.5 EMERGENCY PREPAREDNESS The BEC Emergency Preparedness Plan (EPP) was issued in 2008 and has been updated periodically since, with the last update in 2011. The format of the EPP does not comply with current best practice for emergency...

AI summary The BEC's Emergency Preparedness Plan (EPP), last updated in 2011, does not comply with current CDA Guidelines. The BEC considers actions such as updating contact information, establishing TARP water levels, and updating inundation maps to achieve compliance.

5 CONCLUSIONS AND RECOMMENDATIONS Factorydale dam is regulated by the Nova Scotia Department of Environment and Climate Change (NSECC) through a water withdrawal agreement. With an estimated reservoir storage capacity of less than 30,000 m...

AI summary Factorydale Dam is regulated by NSECC and does not meet CDA Guidelines criteria. Analysis suggests the 2008 inundation limits overestimated risk, leading to a revised consequence classification from High to Significant. The BEC is advised to update inundation limits for better emergency planning.

AI summary The document outlines various structural issues and recommended mitigations for a dam and associated infrastructure, including loose nuts, seepage, erosion, and public access risks. Priority levels are assigned to each issue, and mitigation strategies are proposed.

For Immediate action; • Floating debris was observed to impede spillway discharge. A debris management plan that may include a debris boom is required to ensure full operational capacity for the inflow design flood.

AI summary Floating debris was observed to impede spillway discharge, necessitating a debris management plan, potentially involving a debris boom, to ensure full operational capacity during the inflow design flood.

1.1 Emergency Preparedness Plan Report (Meco, 2011) An Emergency Preparedness Plan (EPP) was prepared in 2007 and updated in 2011 (Meco, 2011). The purpose of the EPP is to detect, prevent and react to an incident at Factorydale Dam. The E...

AI summary The Emergency Preparedness Plan (EPP) for Factorydale Dam, updated in 2011, outlines procedures for detecting, preventing, and responding to incidents. It includes roles for key personnel, evacuation zones based on inundation mapping, and regular training. The dam is classified as high consequence due to life safety risks, and the IDF is a 1,000-year flood event with a peak inflow of 125 m3/s.
