The runoff <br />from one inch of rain <br />over three days breached <br />the dozer basin above <br />the pond and deposited a <br />large sediment delta, <br />filling the bond to <br />capacity with sediment. <br />A boulder was lodged <br />inside the flume. The <br />flume (photo 5), had <br />been overtopped as a <br />result of a debris jam, <br />consisting mostly of <br />grass and small woody <br />debris. The flume was <br />cleared at the time of <br />inspection, (photo 6). <br />The channel below <br />appeared intact at time <br />of inspection. <br /> <br /> <br />TOPSOIL -Rule 4.06 <br />Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution <br />4.06.4: <br /> <br />o Topsoil piles at the north and west areas of the permit were observed and found to <br />be stable well vegetated and adequately marked. No instability was apparent. <br />o No rilling or gullying was present at any of these sites. <br /> <br />Twelve development drilling sites drilled at the I and J pits and located at the west end of the site were <br />visited during the inspection, (Map 1). The division collected a GPS point utilizing Arc Collector and a <br />Samsung Galaxy phone at each site observed, with the exception of sites 2017 J R4CCR and 2017 A R <br />Breach in dozer <br />basin above pond. <br />Large sediment <br />delta in pond.
