4.0 OPERATION AND RECLAMATION STATUS <br />The text contained in the original section 4 beginning on page 4 -1 is mostly obsolete since <br />the mine has been reclaimed. It is difficult to revise approximately 144 pages of text <br />without losing some valuable historical information. The purpose of the following <br />discussion is to describe the status of the mine site and loadout as of the date at the <br />bottom of the page. This will assist the reader of this permit to understand the portions of <br />this section that are no longer applicable to the operation. <br />Mine Status <br />The disturbed area at the mine site has been granted full and final bond release except for <br />the 4.1 acre developed water resource area. <br />All of the structures at the North Thompson Creek No. 1 Mine and No. 3 Mine were <br />removed from the site during 1986 and 1987. The foundations and some of the structures <br />were buried on site. During 1987 the No. 1 and No. 3 Mine sites were contoured and <br />reclaimed. The base of the concrete box culvert in North Thompson Creek through the No. <br />1 Mine area was left in place to assure creek channel erosion did not occur. Originally, the <br />concrete base and stream banks were covered with riprap. However, high flows moved the <br />riprap off of the concrete base. The concrete base will be permanent to provide creek <br />channel protection which will in turn assure the No. 1 Mine portal area is not eroded which <br />will protect the permanent water treatment facility. <br />During 1988, the No 1. Mine filled with water and started to discharge. The portal area was <br />excavated in order to control this seepage. One of the portals and a flooded air shaft were <br />exposed to control the mine seepage. <br />As of June 1998, all of the seepage water from the No. 1 Mine was emerging from the <br />shaft. The water from the shaft is conveyed to the long pond through a 6 -inch pvc pipe. <br />During late 1998, the Operator backfilled the portal area. A 36 -inch culvert was placed in <br />the fill to provide access to the flooded air shaft. In the event maintenance on the 6 -inch <br />pvc pipe is required, access to the air shaft will be through the culvert. <br />Permit Renewal 4 -i (Rev. 03/13) <br />
