Regra ingorStabilizingRills and Gullys
Seeded areas will be monitored following spring snowmelt and heavy rains. If monitoring indicates
the presence of excessive rills and gullies, closer observation will be used to determine the cause of the
gullying. These areas will be identified on a map.
Natural geomorphic processes in the reclaimed area will be emphasized, taking into account the slope,
aspect, and soil conditions of the site. Further consideration will be given to the normal climatic
patterns, plant successional processes, and rate of vegetation establishment and development in the
subject area. Evaluation will include whether the rills and gullies will prohibit successful revegetation
or will disrupt the achievement of the postmining land use.
Based on this evaluation, several options will be available to correct the situation. These options will
be a direct result of studying the situation and selecting the option that will best rectify the erosional
• problem. One or more of the following options and corrective methods will be employed.
