<br />III. Comments -Compliance <br />Below are comments on the inspection. The comments include discussion of <br />observations made during the inspection. Comments also describe any <br />enforcement actions taken during the inspection and the facts or evidence <br />supporting the enforcement action. <br />2) A second problem was noted in the area of cuhert inlets. 1'he ditches <br />running along the haul road have serious erosion problems before they <br />reach the culverts. 1'he ditch graces steepen causing erosive velocities and <br />head cutting. l;rosive sections of the ditches should be regraded and <br />stabilized with channel riurau. <br />31 A similar problem was noted in the ditches leading to the culverts <br />serving pond E. On the east and west side of the access rosd the ditches <br />have grades that cause erosive velocities. Gullies 3t3" and 'L2" deep were <br />eroded for 10 feet segments on either side of the rosd. 'fhese areas will <br />require regradini; and ditch riurau. <br />91 The b1SHA safety berm along the access road, as it crosses the <br />drainage to pond U, creates a hydrology problem that needs fixing. 'Cite <br />runoff from the road runs along the berm to the bottom of the drainage <br />then breaks through and runs to the pond. 'f he `L breakouts have eroded <br />gullies on the road embanxment; one was measured at 39" deep. The two <br />breakouts need re¢radin~ and riprapin>s to urevent further erosion. <br />These were determined to he violations because Nule 4.O~.b(2) require that the <br />operator use sediment control measures and reduce erosion by: <br />le) lliverting runoff using protected channels or pipes through the <br />disturbed areas so as not to cause additional erosion; <br />and <br />(f) l:stng straw dikes, riprap, check dams, mulches, vegetative sedimeuc <br />filters, dugout ponds, and ocher measures that reduce overland flow <br />velocity, reduce runoff volume, or trap sediment <br />Also, Mule 9.03.2(-1)(e)(iii) requires that "Drainage pipes and culverts shall 'oe <br />constructed to avoid plugging or collapse and erosion at inlets and outlets. <br />Ponds F and G were inspected and were in good condition. hitches to these ponds <br />were clear as were the culverts. <br />Pit 1 was inspected and no concerns were noted. <br />done of the ponds at this mine were discharging during the utspectton. <br />Ao problems were noted in the shop area. "C he spill containment system was w.;ll <br />constructea and free from oil and grease. <br />3 <br />
