4 <br /> K COMMENTS-COMPLIANCE <br /> Below are comments on the inspection. The comments include disccssion of observations made wing the <br /> inspection. Comments also describe any enforcement actions taken during the inspection and the facts or <br /> evidence supporting the enforcement action. <br /> This was a partial inspection conducted by Janet Bmns and Byron Walker of CDMG. The mine is <br /> reclaimed and the permit ham been revoked. No facilities remain on site. No personnel are connected <br /> with this mine site. <br /> The focus of this inspection was to Mow up on the two slides noted in Division of Minerals and <br /> Geology's May 11, 1998 inspection. Mr.Walker assessed the site in terms of engineering stability. <br /> Mr.Walker's interoffice memo accompanies this report. <br /> The slide West of Pit 4 did not appear to have enlarged since the May 11, 1998 inspection. It appeared <br /> that the ran out of the slide had reached Grassy Creek,but had not blocked the creek. Grassy Creek <br /> was flowing unimpeded at the time of this inspection. The dimensions of the mudflow are visually <br /> estimated and paced at 40& Wide by approx. 120& Long,with the toe of the slide spreading to—90 <br /> &wide. Water is flowing out of the slope of the slide at approx Lees than 3 gallons per minute. <br /> Investigation of Pond 4 at the base of Pit 4 finds the riser undercut and piping along riser to have <br /> occurred. Piping is not apparent on outslope of embankment Just below the pond embankment on the <br /> west side of the pond outslope vegetation consists of very dense oak brush Thorough investigation of <br /> the slope below the pond is limited by the dense vegetation The head of the scarp below the pond was <br /> accessed. Head scarp originates approx 70-90& Below the pond embankment. Gullying in slope <br /> above the scarp and below the pond embankment was observed Slide head scarp is approx 5 &in <br /> height A sediment delta apparently from the run out of the flexible pond riser sleeve has accumulated <br /> at this location. A spring firm the hillslope also exhibits itself here. Visually it appears that natural <br /> causes contribute to the formation of the slide,however,contribution of concentrated water from Pond 4 <br /> may add to the instability of the slope. <br /> Hairpin turn on the access road to Pit 4 continues to cut <br /> Piping of the ditch along access road to Pit 2/3 has occurred. R*V placement in the locale may <br /> provide necessary reinforcement Spring down cutting of access road 2/3 continues. <br /> Interoffice memo included as a part of this report <br />
