offices) I would request a minimum of four copies anyway. Beyond that amount, I will leave it up to you whether you wish to provide additional copies for the other permit files. The scale for this map is appropriate, and the inclusion of the details of all possible sites (most considered as "affected" but some probably "pre-law") does not clutter it due to the color and symbols used. It sounds as if there is a question whether the permitted and pre-law disturbance at the GMG mine area should be left on this map. I believe that this azea qualifies to be on the map as much as the others do, and should remain on the map. (Since it was affected as part of the operation of the Sunday Mine, it should also be specifically included on the maps for that permitted site also.) Perhaps the main question, however, pertains to the depiction of the GMG area affected by both permitted and pre- law activities, and IUSA's reclamation liability for each. It is clear that there is pre-law disturbance here, and if parts of it were not redisturbed under this permit and are not planned to be redisturbed in the future, then those areas do not have to be included in the affected area acreage. (I will discuss this particular site further, under the next section.) Related to that is the general issue of ensuring that all items shown on the maps as pre-law or otherwise not liable to be reclaimed, that an adequate (but brief) description is made for each, so that if appropriate to do so, they may be clearly eliminated from the list of reclaimable disturbances. This type of description should be provided for each vent hole or other underground opening, above-ground structure or road segment, for which this office has no other information or conflicting information. Descriptions of vent holes and underground openings must be adequate to determine if hazards exist. 2. Sunday Mine, Full Coveraee of Permit Area, Includin¢ Roads and Vent Holes. There are numerous vent holes, their related above-ground support structures, and other remote features associated with this permit. Given that we must begin discussion about each,, and they are not to my knowledge each "named" per se, I wondered if IUSA has an internal identification scheme.(as you had identified WS-1, WS-2, etc.). Is there any merit to "naming" each feature so that we may refer to them by means other than their NAD coordinates? You raised the question about three specific vent holes, and though they appear on the Sunday Mine map, you are not sure to which permitted site they actually belong. Those three;vent holes (WS-1, WS-2, and WS-3) aze actually approved under two separate technical revisions (TR-01 and TR-02) for the West Sunday Mine permit (no. M- 1981-021). Detail about the electric power and road features associated with these three vent holes is lacking from the early file materials, but is included on your new map. These features may remain on the Sunday Mine map if you wish, but should be clearly labeled to show they are included in a different permit. It would be clearer to not include them on the Sunday Mine map, and to include them only on the West Sunday Mine map. (I discuss these features in a separate letter, concerning the map of the West Sunday Mine site.) It should also be pointed out that the electric supply features, access roads, service holes and compressor must be included in the delineation of "disturbed area." There are two other vent holes shown, along with their associated electric power and road features, in a location perhaps most easily described by the approximate NAD coordinates 528300 N and 1045900 E. These happen to be a couple of the undocumented features I found during my 12(18/01 inspection, which were obviously not pre-law. They must be included in one of the permitted sites, though I am not sure which. I am under the impression that most, if not all, these five separate permitted sites are connected underground. Is that correct? If so, then it would be easiest (from my perspective) to attach these vent holes to the permit which was written to allow for adding this type of remote site in the future. I believe the Sunday Mine permit allows that as a technical revision, without the need for filing an amendment. This is your decision; but ultimately the features must be shown on the maps for the permit in which they will be included. (As mentioned above, all features associated with these remote vent holes must also be included in the delineated disturbed area.)
