~II II~II~~II~~I~ ~I~ sss IV. ENFORCEMENT ACTIONS The following identifies enforcement actions taken during this inspection, the required abatement and date of abatement for the violation, previous violations still requiring abatement and the termination of violations cited during previous inspections. 1. Drainage and sediment control problems at the Super Curve, West Ridge Access Road have resulted in excessive erosion. Water has flowed down the inside of the tight curve in the road referred to as the "Super Curve," creating a series of gullies down the slope into undisturbed area around the drainage. The water came from both sides of the access road. Drainage following the ditch on the northwest side of the road, consisting of water collected over a distance of nearly 2800 feet, reached a location on the inside of that curve and flowed down the embankment from the road into the drainage. Additional water flowed across the road from the southeast side of the road (the uphill side), apparently because the ditch was blocked and also flowed down the embankment into the undisturbed drainage area. Note that the operator cut a temporary ditch directing drainage from the northwest edge of the road across the road where it will flow into the engineered drainage system. The gullies caused by this lack of drainage control are as deep as 2 feet on the upper embankment, which consists of the reclaimed portion of the road. The gullies increase in size where the embankment steepens in the undisturbed, vegetated portion with one reaching a depth of 4 feet. At the bottom of the embankment the sediment has been deposited in an alluvial fan where the gradient of the embankment flattens. Here native vegetation has been partially buried by sediment of all sizes in a depositional lobe reaching 50 feet from the toe of the embankment, 25 feet wide, and depths reaching as much as 8 inches. 2. At the North end of the Moffat Pond, drainage and sediment control problems caused water to overflow the North Diversion Ditch bypassing the pond. The drainage water flowed west through the former Trout Creek pump pad, creating a significant gully, down the embankment to the west, ultimately into Trout Creek. Disturbed area drainage flowed offsite without first passing through a sediment pond. The cause of the overflow and short-circuit of the ditch-pond system is not certain. Apparently the water level in the pond was sufficiently high to contribute to the backup of water in the ditch. A further contribution probably came from the deposition of sediment at the outflow of the Final Moffat Drainage Ditch, directly adjacent to the outflow of the breeched ditch. The blockage appears to have resulted from severe erosion of the Final Moffat Drainage channel uphill from the pond. Sediment ranging in size from silt to
