Michigan's Cascading Dam Failure - An Ethics Case Study Slides

Pdf Summary

This document summarizes key findings from two reports on the 2020 failures of Michigan’s Edenville and Sanford dams, focusing on preventable points and ethical issues surrounding their design, construction, maintenance, and operation. The Edenville Dam, built in 1925, experienced numerous compliance failures under Boyce Hydro’s ownership after 2004, with repeated violations related to permits and spillway capacity ignored despite Federal Energy Regulatory Commission (FERC) notices from 2009 through 2017. FERC eventually revoked the hydroelectric generation license in 2018 due to noncompliance, transferring dam jurisdiction to the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The dam failed catastrophically on May 19, 2020, following significant rainfall and high river levels, causing extensive flooding, infrastructure collapse, and environmental damage.<br /><br />Analyses reveal multiple preventable failures including inadequate construction methods diverging from original compacted-lift designs, insufficient embankment stability assessments focused on unrealistic favorable conditions rather than worst-case scenarios, and ineffective regulatory enforcement, as FERC could revoke licenses and fine but lacked power to compel remediation. Funding shortfalls could have been mitigated earlier by public-private partnerships, such as the Four Lakes Task Force, which was eventually formed post-failure to facilitate repairs and upgrades. Despite dam failures, no loss of life occurred, credited to early evacuation and emergency management actions, although emergency plans showed deficiencies.<br /><br />Lessons learned emphasize the need for comprehensive watershed-based dam safety oversight, improved regulatory authority to enforce maintenance and repairs, better engineering analyses, and preemptive funding strategies. Ethical concerns emerged around ignoring repair requirements, incomplete or inaccurate safety reporting, and environmental damage during unauthorized water drawdowns. The report calls for responsibility across all stages—from design through operation—and the importance of transparency and accountability to prevent future dam failures.
