The affected area boundary is not shown on the map for this site, though there is a delineation presumed to show <br />the outer "footprint" of all past disturbance. This permit was written to allow up to 40 acres of affected area, in <br />locations to be documented at those times when they are needed, It is felt that all disturbances which occurred <br />under this permit are presently less than that 40-acre total, though the exact acreage is not known. This flexibility is <br />not the way by which this Division presently approves future expansions of permitted operations, and it is now time <br />to concretely define where the boundaries are to be fxed. This case presents a raze opportunity to configure the <br />affected area boundary to include all existing permitted disturbances (reclaimed or not, since no request for acreage <br />release has yet occurred) and also areas which will.be additionally disturbed in the future, up to a maximum of 40 <br />acres. Acreage beyond that may be approved, but only through a permit amendment. Your final map versions <br />must show such a boundary, configured as you deem best for your future operations, but constrained according to <br />the criteria given. Straight sides with definite corners aze obviously the easiest to mark. <br />8. GMG Mine Area, as part of Sunday Mine: <br />Discussion was given previously for this remote sife included in the Sunday Mine permit. It is appropriate to depict <br />it on the large map which shows the entire Sunday.Mine (portal azea as well as the remote sites). It is not necessary <br />to prepare a final version of the map showing only this single site. <br />As mentioned above, pre-law disturbances not redisturbed under this permit aze not required to be included in <br />permitted acreage and not liable for reclamation or bonding. Stormwater control structures, underground openings, <br />roads, overhead electric structures, waste rock dumps, debris areas, etc., which have been disturbed, constructed, <br />installed, maintained, graded, filled, etc., since this 1977 permit was issued, all must be included in the affected <br />area..Areas which aze planned for future disturbance should be included also. Once that is established, details of <br />the final reclamation may be finalized. <br />Summary <br />These comments and questions will hopefully assist you in finalizing the maps for this permit, by explaining how <br />this Division proceeds in determining which areas and features aze to included in the bonded reclamation liability, <br />and within the boundary on the maps. Your preliminary map products are a very good start, and should take <br />minimal effort to reach a complete and adequate stage for our uses. <br />I look forward to receiving the final versions. Please ensure that you submit all maps, especially oversized maps <br />(larger than 1 I" x 17") in duplicate. It would be more convenient for our reviews of permit materials if they were <br />not submitted as groups of permits treated under one letter, but rather individually, if that change can be made. <br />Additionally, all final maps aze to be signed by tfle preparer.. As before, please do not hesitate to contact me if there <br />are questions. I may be reached, and/or the maps mailed to the Division's Durango field office: 701 Camino del <br />Rio, Room 125, Durango, CO 81301; telephone 970/247-5103 or fax 970/247-5104. <br />Sincerely, <br />~~~ <br />Bob Oswald <br />Environmental Protection Specialist <br />A:\sunday and group maps/rco <br />
