Shelton Director July 13, 1981 Mr. Richard Dougherty S'ampa Mining Company P.O. Box HH Hayden, Colorado 81639 Re: Hayden Gulch Application Our File No. C-003-80 Dear Mr. Dougherty: We have come to a point in our review where ire are able to make some findings of compliance for the above-mentioned permit application. There are a few issues, however, which will need to be resolved before we can make a decision to grant a permit. Some of the more major issues pertain to information that H-G has committed to submitting (during meeting of 5/29/81), but which the Division has not yet received (as of 7/9/81). The purpose of this letter is to outline these ommissions and also to identify other areas of deficiencies which need to be rectified prior to issuance of a permit. The information which is still pending consists of the AVF study, a swell factor study, wildlife mitigation plan, geotechnical analysis of the overburden waste dump, and geochemical analysis of overburden and interburden. Addition- ally, Larry Jackson was preparing submittals dealing with the reclamation plan for the loadout, stream reconstruction and reclamation plan for the ponds South of HG-8 and East of the county road, and resubmittal of the final contour map (Exhibit D). Please submit these materials as soon as possible. Zn addition to the above, our staff has identified concerns which need to be clarified before the Division can issue a proposed decision. A major problem is related to the vegetation study. The response to concerns raised during the adequacy review is not entirely acceptable. I suggest that the enclosed memo from Mike Savage be forwarded to David Duba for his perusal. Co:rvnm~ts or questions should be directed to Mike Savage. Essentially, Mike has determincrl that some reference areas are unacceptable for use as revegetation standards. The following problems were identified relative to the reclamation plan. [•le request that you provide further clarification of these issues so they can be readily understood:
