(1) General maintenance
and ordinary repairs that do not require a construction permit
are those activities that do not impair the safety of the dam if done properly.
These activities include:
(a) removal of brush or weeds, or cutting of trees, removal of slash from the
embankment or spillway, and removal of small stumps is included, provided no
deep excavation into the embankment occurs;
(b) repair of erosion gullies or minor rodent damage on the embankment or in the
spillway (Large gullies that have already weakened the dam must be repaired in
accordance with ARM 36.14.306) ;
(c) surface grading of the embankment crest or spillway to eliminate potholes and
provide proper drainage, provided that the freeboard is not reduced; and
(d) placement of additional riprap and bedding on the upstream slope, or in the
spillway, in areas that have sustained minor damage. This would involve
restoring the original riprap protection and maintaining the original capacity
where the damage has not yet resulted in weakening of the dam.
