The water was being <br />used for dust suppression on the roads. The pump at the NH1 Pond was in a rubber lined container to contain <br />spills. The area appeared to be clean (photo 3). <br />Pond 002 appeared to be almost complete. It did not contain water (photo 4). <br />The north ditch of Pond 002 was free and clear of obstructions and appeared to be almost complete, except where <br />the ditch drains into Pond 002. The ditch inlet into Pond 002 is the subject of TR -9 which was issued on March <br />31, 2015. Best management practices were discussed for the area between the Pond 002 north ditch disturbance <br />and Meehan Draw (photo 5). Topsoil was stripped up to the Meehan Draw stream buffer zone. In the spots where <br />the topsoil was thick, bench 1 material from the ditch construction was backfilled against the topsoil to protect <br />Number of Partial Inspection this Fiscal Year: 7 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 2 of 5 <br />
