Lochhead <br />Execmrve Director <br />Michael B. tong <br />Division Director <br />Thank you for submitting the above-referenced permit maps which were received by our office on <br />4/25/98. I have a few comments about the maps in general, and some specific questions about the <br />individual maps. I reviewed the maps carefully, comparing them with the existing ones in the files <br />and checking Hard Rock/Metal Mining Rule 6.4.3 and 6.4.6 for the Sunday Mine, and Rule 6.3.5 <br />for the other three mines. These lutes define the general map standards for 112 permits and 110 <br />permits, respectively. The rules give guidelines for representing both mining and reclamation <br />features. Below are my comments: <br />General notes <br />The maps in general are clearly drawn at an appropriate scale, and show most of the important, <br />current features. In most cases the boundaries and features correlate to their counterparts on the <br />earlier maps. There are, however, some significant differences between earlier maps and these <br />current ones. My comments about the maps in general are 1) a locatable reference point (such as <br />a surveyed section corner) must be included; 2) certain onsite structures appear to be absent from <br />the new maps, without an explanation (omitted or actually removed?); 3) stormwater/sediment <br />control structures, observed during inspections in 1997, are not depicted though they should be; <br />4) besides the waste bench outslopes, there is no topographic or surface drainage information; 5) <br />certain outlying features (a vent shaft and its access road, for example) are not shown though they <br />are specifically included in the permit. <br />
