• MINE ID # OR PROSPECTING ID # INSPECTION DATE 11/10/94 (Page 2) • M94-005 INSPECTOR'S INITIALS RCO This inspection was performed by the Division to monitor the existing permitted operation and to assess the Bite and plans involved with the proposed expansion (Amendment 001). Paul McGehee was contacted about the inspection and met this inspector at the site. The amendment application was briefly reviewed in the office. This inspector and Mr. McGehee were then accompanied by the Bite manager, Mr. Mayger, during the inspection of the several phases of the operation. APPLICATION REVIEW ~.J This will be covered in detail in the adequacy review letter. Some of the main questions concerning the application materials were as follows: ~ The use of a new haul road on the southeast side of the expansion area. The road should be included in the permit area. Also ensure that if no cottonwoods, etc., are to be affected by the road, that it is not depicted to pass through them. ~~, The existing topsoil berm (plus trees to be planted) along the north aide are not shown on any map. Be sure that all et ructuree within 200 feet of the boundary are shown on a map. Private -' dwellings were observed near the northeast and southeast corners of the expansion area, and possibly within 200 feet. ~, The applicant has an engineering study stating that disturbance may occur as close ae 30 feet to a structure with no negative impact. If disturbance is planned to occur at distances less than 200 feet to any structure, the structure's owner must provide a statement regarding liability for damage. ~+ There is a corner of Phase II shown to be outside of the permit area on the map. The boundaries of the phases and permit area should be clarified. SITE INSPECTION The weather was calm, with no dust blowing during the inspection. Within the existing (Phase I) area, the crusher had been moved offsite, and the noise level of its operation was therefore unable to be assessed. No offsite disturbance was observed during the inspection. The topsoil stockpiles were in place on the west and north sides of the Phase I area. They are not presently graded or seeded, but seem to be stable for the interim. They have been left until fall seeding in a rough and "chunky" state. The operator explained how the pileai surfaces will be smoothed and seeded at a date later this month (as recommended by the SCS). The operator will please notify the Division as to the timing of the grading, seeding and planting of the berms. The access road along the north was watered. An overhead water tank for the spray truck is kept permanently full. Water for the tank is pumped from the ditch which passes on the east side of Phase I. The ditch, which is planned to be rerouted by piping around the west side of Phase I, was currently flowing. The required permit sign and markers were observed. There were about 10 acres now mined. Depth was about 20~feet, and aide elopes were about 3:1. Stockpiles of primarily gravel covered about 10 acres. Piles reached a height of 30 feet. A wet area of about 5 acres was seen in the northeast portion of the expansion area (Phase III) and in the adjacent off-permit area, down on the bottomland. The site seemed to be a flooded pasture or hay field, and not a perennial wetland, judging by the vegetation. However, these areas can be sensitive, and thorough assessment might not be possible in one inspection. If operations are proposed to occur there or nearby, the operator should provide information as to source of water on that site, and seasonality and nature of surface and/or groundwater at the site. The area should be adequately represented on the map also. A pond structure excavated in the southeast corner of Phase I is present, though not used, because of the tank mentioned above. It is stable, and will remain until mining reaches that corner.
