c) On page 8 of the application, the operator States" Gypsum will a removed in 50 -100 foot panels preferably by bulldozer, but if drilling and blasting became necessary, it will be performed by a licensed contractor". Prior to implementing any kind of blasting, operator will submit a blasting plan and get approval from DRMS. Even though the proposed planting procedures will not.likely generate a peak particle velocity high enough to affect any manmade structures such as High Way 115 and access road. However, if blasting is going to be implemented, DRMS would like to see the plan and grant an approval. III) Exhibit E Reclamation Plan 6.4.5 A) It is the understanding of the Division that the site will be reclaimed as range land and the operator had committed to salvaging all available top soil or growth medium. During the pre- operational inspection and the test pits noted, some of the area appears to yield more top soil than was reported in the original 110 application. B) GCC'S current maximum phased affected acres total 104.33 acres of the total permitted area. Since the current total proposed permitted acres is over 500 acres, DRMS recommends GCC to look at the proposed plan and increase the maximum affected acres more or less in line with the maximum potential mining areas, in order to avoid future amendments to add affected acres. GCC will not be required to post a financial warranty more than what they will affect and proposed to affect at any given time. C) On page 10 of the application the operator states," Reclamation will be consistent with the approved plan and technical revision currently described in M- 1997 -064, including seed mix and re- vegetation procedure. DRSM will not object to utilizing the seed mix and other applicable reclamation procedures as suggested by the local soil conservation district, however, in looking at the old 110 permit they did not even agree there was even a growth medium available, so DRMS would like the operator (GCC) to proceed with the reclamation as described by the local sol conservation district for Fremont County. The blending of the slopes should be consistent and should blend with existing natural topography. IV) Exhibit G Water Information 6.4.7 A) During the pre- operational inspection and what hat is noted In the mining and reclamation maps, there are a couple of dry gulches intersecting the permit area along the NW side and N.E side of the permit area. Based on what is included in the NE portion of the affected area, the proposed phased mining plan appears to intersect the drainage. The operator states, "Run off occurs as overland flow to vegetated dry creek beds or drainage ravines in the vicinity. However, once an area is affected, it is the responsibility of GCC, to implement and minimize impacts to these dry creek beds from receiving affected drainage. Please explain in detail how GCC is going to minimize impacts to these drainages from the proposed mining activity. B) The operator states that there are no known wells within 200 feet of the proposed activity. However, the rule is to identify all known wells within 600 feet of the permit area that could be impacted by the proposed operation. Are there any shallow wells located within 600 feet of the proposed permit area? Please explain.
