<br />INSPECTION REPORT - PAGE 2 <br />FILE NO. M_77~pp4 <br />DATE: Julv 17. 1986 <br />OBSERVATIONS OF IMPORTANCE: <br />1. Inspector met with Mr. Jim Piper on-site. <br />Z. The lower sediment pond is filling, but flows seem to be contained. <br />The pond should be maintained and extended to the north, possibly to the <br />adjacent fence. <br />3. Much runoff has left the stockpile area above the restaurant and is cutting <br />the south side of the access road. Sediment is being deposited off site, <br />south of the access road. <br />4. Internal sediment ponds look good (along mine road). <br />5. All of the gullies mentioned in the May 2, 1986 report have been partially <br />checked; however, work still must be completed to remedy the prot~lem. <br />RECOMMENDATIONS: <br />1. Extend the lower sediment pond to the adjacent fence and also thfa rock berm. <br />Maintain as needed. <br />Z. Erosion and deposition along the south side of the a:cess road is a problem. <br />Eventually, a sediment pond may be necessary, but for now, incre;ise the <br />upper berm (stockpile area) by using coarse material to bolster 'the existing <br />berm. We recommend that an additional berm be placed between the "growth <br />medium/visual berms" (just south of the office parking area). This will <br />help slow flows and trap some sediment. <br />3. All gullies mentioned in the May 2, 1986 inspection report should be filled, <br />by using large rock (rip-rap size) to hold the toe, and then filled in with <br />gravel. Fines (asphalt fines/sands) should not be used since they will <br />quickly wash out. The large gully north of .the main plant seems stable, <br />but all other gullies (north of stockpile area, adjacent to gulch and above <br />the restaurant) should be filled and maintained as discussed above. The <br />fines used to fill the berm should be removed where feasible since they <br />will only wash out over a relatively short time. <br />4. Please complete these measures no later than August 17, 1986 and notify us of <br />the completion. <br />(Rev. 9/63) (OVER) <br />Doc. No. ~2~P <br />
