<br />ENVIRONMENT, INC. <br />MARCH 26, 200 7 <br />PAGE 3 <br />designated was to give the operator the flexibility to place <br />various processing plants in it, in unspecified locations. We <br />will keep that flexibility and state again that the Plant Site <br />may contain but is not limited to gravel processing equipment, <br />gravel stockpiles, an asphalt batch plant, a concrete batch <br />plant and/or a concrete casting facility. P~ocessing_plants <br />do not need to be placed in the bond calculation since they <br />will be allowed-under-ouf.county-permit and_.wo_u_ld.be_removed <br />as an~-a_sset""if--mining ended prematurely. All necessary <br />permits needed from other"government agencies that apply to <br />these plants will be obtained before operating them. <br />9. All roads used by this operation will be contained on site or <br />are county roads. The on site roads will not be improved <br />unless used as a haul routes and in that case they will be <br />maintained regularly and graveled to keep dust down. Most of <br />these roads will remain when mining ends to allow access to <br />oil well facilities on the site. Existing roads vary from 12 <br />to 25 feet wide depending on their use. The new access road <br />will be constructed from the southeast corner of the site to <br />the Plant Site in the approximate location shown on the mining <br />plan map. This road will be up to county standards, probably <br />50 feet wide with a gravel surface. Drainage ditches will be <br />along each side to collect any runoff and channel it to <br />drainages that cross the site now. As stated in the appli- <br />cation, no water that comes in contact with disturbed areas <br />will leave the site unless it is allowed under our discharge <br />permit. <br />10. So noted. This was an advisory statement to make all inter- <br />ested parties understand that changes to the end use may <br />happen. This keeps someone in the future from saying they <br />were never told the possibility existed. I might point out <br />that~if PS&G chooses to seal one of the lakes, fill it with <br />water they purchase/own and use it for recreation is does not <br />change the final reclamation plan. <br />11. At this time PS6G cannot predict the exact areas where <br />dewatering may take place in each area. At this time the <br />plans are to dewater a very small area in each lake area. <br />This will create an area where the dredge can be set and/or <br />built on the floor of the excavation. Once the setup is <br />complete the pumps would be shutoff and the excavation would <br />refill, floating the dredge so mining could resume. The area <br />of dewate~ g will be li_mited_5 acre or less in_each lake area <br />~as far from the permit boundary as possible. The depth mined <br />would be limited to 15 feet below the static water level or <br />less, to reduce the impacts to surrounding wells. The <br />dewatering period on each small area may extend up a year to <br />allow time to remove the gravel from the hole and setup the <br />dredge. <br />
