'1r1 ~ • <br />Cotter Corporation <br />Ms. Camille M. Farrell <br />Mined Land Reclamation Division <br />July 17, 1985 <br />Page Two <br />J <br />b. No erosion has occurred as the mine water is totally contained by <br />the evaporation pond. <br />5. a. (1) C-JD-6 (77-310) (110 permit - Limited Impact) <br />The disturbed area is as permitted (6.24 acres). Reclamation <br />of this area cannot begin until the mine is permanently closed. <br />The disturbed areas around the vent holes, however, have re- <br />vegetated themselves with native grasses and forties. Also, <br />the 351 exploration drill sites at this site have been reclaimed <br />and seeded with approved seed mixture. <br />(2) C-JD-7 U.G. (77-308) (112 permit - Limited Impact) <br />The disturbed area has not reached the total permitted acreage <br />(9.29) as only one (1) of the vent holes has been constructed. <br />The evaporation pond area was converted to a two (2) pond dis- <br />charge system as mentioned earlier. The pond and vent hole <br />areas have revegetated themselves quite satisfactorily. The <br />exploration drill holes on this property were obliterated by <br />the pit construction adjacent to it. The other permitted vent <br />hole area will be utilized sometime after production is resumed. <br />(3) C-JD-9 (77-306) (110 permit - Limited Impact) <br />The disturbed area has not reached the total permitted acreage <br />(8.25) and the amendment acreage (2.85) as the addition to the <br />waste dump has not been utilized due to the cessation of pro- <br />duction. <br />The revegetation of the vent site shows excellent growth as <br />well as the water discharge pond area. All drill sites were <br />reclaimed and seeded in 1981 with excellent results. <br />(4) C-SR-13A) (110 permit - Limited Impact) <br />The disturbed area is as permitted (9.69 acres). Reclamation <br />of this area cannot begin until the mine is permanently <br />closed. However, all drill sites at this site have been reclaimed <br />and seeded. The revegetation of this area is limited due to very <br />limited topsoil with mostly rock outcroppings. Presently, we <br />are reworking the drill sites and vent hole areas and will <br />reseed again this fall. <br />
