r (Page 2) ~ MINE ID # OR PROSPECTING ID # M-89-030 INSPECTION DATE 10/09/97 INSPECTOR'S INITIALS RCO This inspection was performed by the Division as part of its monitoring of 110 permits, and as a pre-operation inspection of the area the operator wishes to include in the permit. The operator has submitted an application to convert the 110 permit to a 112 permit. The operator was ~:ontacted about arranging a time to meet at the site; he and the consultant who is preparing the application were present throughout the inspection. The 110 permit area was inspected first, with the following items noted: 1. The permit ID sign was posted at the entrance to the site, and several of the boundary corners were marked by steel t-posts. However, the post to indicate the SW corner had been knocked down by equipment onsite, and the boundary could not be exactly identified on the ground. The:ce was some ~oossibility that a small area (approx 0.5 acre) outside the west boundary line was disturbed by mining-related truck traffic. The damage consisted only of truck and loa~9er tracks on the soil surface. It is within the area which has been proposed to include within the converted permit. Due to this uncerta inty of the bounda ry lo cati on nd i e r la io n o h k aff~ imya ct, the topic o f "off- site damage" is not ed o nly as a prob lem (P B1 on pave one of this repo rt. The correc tive a ction is desc ri bed here an d on the l ast pa ve of the report. The oper ato r mus t submi t one of th e follow in g it ems: 1) dete rmine by me ans of a s urvey of the pres ent 110 Hermit a rea w hether the ab ove -na med dist urban ce is ac tu all y of f sit e. prepare a man of t he p ermit an d thi s dist urbance . and begi n fu ll r eclama tio n of the off s ite area: or 2) c ompl ete the 112 conve rsion applica tio n, and obta in a 112 p erm it . b y th e de cision date. 2. The operation consists of a hillside pit which daylights on the west side on a bench. There are stockpiles of sand and gravel at the edge of the bench. The pit has been excavated by pushing doom material from above by dozer, leaving stable slopes of slightly steeper than 2:1. The deposit being mined is a deep cobble bed, with some clay. There was no evidence of erosion o:n the slopes or the topsoil piles. There was a small seep at the toe of the highwall, whose discharge was routed out of the pit toward the Nw. 3. There was no processing equipment present, though a crusher had been used onsite to produce the g:cavel in the stockpile. There were four or five bellydumps and a loader onsite at the time c•f the inspection. a. The topsoil is very ciistinet in color, up to about one foot deep, and is stripped and stockpiled along the N and S sides of the pit prior to mining. Woody vegetation covers much of the hillside, and it too is stripped, but not segregated from the soil. The soil generally appears to be stable and not eroding, and sufficient in amount to perform the approved recltunation. There was, however, a small amount of the topsoil at the edge of the bench along the south boundary which is being used as material in a ramp for mine traffic. The tops oil is n ot suitable as a ma ter ial to exp ort and cannot be sol d from a count n it. and therefor e must b e protected . as a re sou rc e to be used ~n rectamat~on.
