2025 Dam Safety Inspection Follow-Up for Flint Creek Hydroelectric Project

Strategic Insights -

The Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, Division of Dam Safety and Inspections, conducted an inspection of the Flint Creek Hydroelectric Project on August 20, 2025. Although no immediate remedial actions were required to ensure the project's safety, FERC identified several items that need follow-up actions by Granite County. These include managing vegetation along the left abutment, updating the Emergency Action Plan (EAP) notification flow charts, and ensuring that the internal copies of the EAP reflect the updated contact information.

Key Takeaways:

  • FERC identified two main areas that require follow-up actions by Granite County: managing vegetation along the left abutment and updating the Emergency Action Plan (EAP) notification flow charts.
  • The vegetation along the groin of the left abutment was observed to be overgrown, limiting visual inspection of this area, and should be managed to a reasonable height to allow for unimpeded visual inspection.
  • The EAP notification flow charts were found to be out of date, and Granite County must update their internal copies to reflect the interim contact information provided by FERC.
  • Granite County must provide a plan and schedule to address the vegetation in the specified area within 60 days of the date of this letter.
  • FERC will contact Granite County by phone and/or email if any additional items requiring follow-up action are identified during the preparation of the Dam Safety Inspection Report.
  • The Flint Creek Hydroelectric Project, FERC No. 12107, features several inspected areas and no conditions that would require immediate remedial action to protect the safety of the project.
