R12-15-1217. Maintenance and Repair; Emergency Actions

A. An owner shall perform general maintenance and ordinary repairs that do not impair the safety of the dam. General maintenance and ordinary repair activities listed under this subsection do not require prior approval of the Director. These repair activities include: 1. Removing brush or tall weeds. 2. Cutting trees and removing slash from the embankment or spillway. Small stumps may be removed provided no excavation into the embankment occurs. 3. Exterminating rodents by trapping or other methods. Rodent damage may be repaired provided it does not involve excavation that extends more than 2 feet into the embankment and replacement materials are compacted as they are placed. 4. Repairing erosion gullies less than 2 feet deep on the embankment or in the spillway. 5. Grading the surface on the top of the dam embankment or spillway to eliminate potholes and provide proper drainage, provided the freeboard is not reduced. 6. Placing additional riprap and bedding on the upstream slope, or in the spillway in areas that have sustained minor damage and restoring the original riprap protection where the damage has not yet resulted in erosion and weakening of the dam. 7. Painting, caulking, or lubricating metal structures. 8. Patching or caulking spalled or cracked concrete to prevent deterioration.
