Matthew S. Hayes <br />June 28, 1989 <br />Page 8 <br />A pit will be constructed on the pad to contain any water or mud used during <br />drilling. Drilling mud, if used, will be contained in the pit during drilling and <br />will be removed from the site upon reclamation to a permitted disposal area. <br />Water and/or foam,if used, will be allowed to discharge on the surface at a rate <br />which will not cause erosion. The foam used will be a biodegradable type which <br />will not damage the environment. Drill hole cuttings will be backfilled into the <br />pit and covered doting reclamation. <br />If water is encountered during drill operations, flows of 10 gpm or less <br />will be discharged on the surface in such a manner so as to prevent <br />erosion. Flows over 10 gpm will either be contained, sprayed, or <br />otherwise discharged in a manner so as to prevent erosion. <br />Water required for drilling will be obtained with permission of the surface <br />owner, USFS, or other private owners, and will be trucked to the drill site <br />from the nearest location available where it can be obtained with <br />permission. <br />The hydrologic monitoring well completion interval will be determined <br />based on conditions encountered in the hole during drilling such as water <br />present, if any, depths to water, and physical condition of the hole. <br />The drilling project will utilize the following general types of equipment: <br />Description <br />Drill Rig Rotary/Core <br />Rig Up Truck <br />Water Truck <br />Small Dozer <br />Roadgrader <br />Backhoe <br />Pickups <br />Auxilliary Compressor <br />Logging Truck <br />uanti <br />1 <br />1 <br />1 <br />1 <br />1 (if necessary) <br />1 <br />2-3 <br />1 <br />1 <br />Upon completion of drilling, coring, and logging, the hole will be <br />cemented, cased, and screened at the interval determined for hydrology <br />monitoring. <br />
