• 2.05.4 <br />Area 6 - Access Road from gate to fuel tanks <br />The access road from the gate to the site (fuel tanks) will not be <br />reclaimed. This road is necessary to provide access to the DMEA <br />easement and site maintenance. The site would be virtually <br />inaccessible without this road. During 1996 or 1997 this road will <br />be vegetated in order to control erosion and noxious weed <br />infestation. The roadbed will be ripped, the seedbed prepared, <br />seeded, fertilized and mulched. The seedmix to be utilized is <br />presented on page 131. <br />Area 7 - Sedimentation Pond <br />The sediment pond will not be reclaimed. It will be left in place to <br />enhance the postmining land use of wildlife habitat. Ponds attract <br />may kinds of wildlife. Migratory waterfowl often use ponds as <br />resting places in their flights to and from the north. This <br />reclaimed mine site has become a refuge for deer and elk. It is <br />isolated and provides good forage. Keeping the pond in place will <br />enhance the use of the site by deer, elk and waterfowl. <br />The source of water for the pond will be the return irrigation water <br />that runs down the major drainage channel. During 1982 through 1985 <br />water from this source was measured (monitoring point SP-A). The <br />• average flow through SP-A was 32.9, 15.8 and 14.6 gallons per minute <br />during water years 1983, 1984 and 1985 respectively. A fifteen <br />gallon per minute flow equates to 2 acre-feet per month. This should <br />be an adequate volume of water to provide a reliable source of water <br />for the pond. <br />The issue of water rights for storage of water in the sediment pond <br />was addressed with Jim Boyd, Water Commissioner, Irrigation District <br />No. 4. An individual from the Water Commissioner's office inspected <br />the site and determined there was no beneficial use of the irrigation <br />waste water downstream of the sediment pond. Therefore, a water <br />right is not required to divert the irrigation waste water into the <br />pond. The following letter dated May 16, 1984 from Minrec, Inc. to <br />the Water Commissioner (page 129a) confirms this discussion. <br />Rule 4.05.9(1)(a) requires the operator to demonstrate the quality of <br />the impounded water is suitable on a permanent basis for its intended <br />use. The operator will obtain at least one sample from water in the <br />sediment pond for this demonstration. The water will be analyzed for <br />pH, TDS, chloride, sulfate, sodium, lead, cadmium, nitrate, nitrite <br />boron, arsenic, chromium, copper, selenium, zinc and aluminum. <br />Results of this analysis will be submitted to the DMG. <br />In order to leave the sediment pond in place it must conform to the <br />requirements of Rule 4.05.9. Following is a discussion of the <br />sediment pond as it relates to Rule 4.05.9. <br />• 129 (Rev. 6-28-96) <br />
