Dear Ms. Rehmann, Bill p.vcns Governor Greg E. Wall her Executive Dirttmr nr~n,el B. Long Division D'veclor I have reviewed the adequacy responses submitted to our office, which were to address the questions raised in our initial review of the above-named application. Your response submittal appears to answer many of the issues contained in our letter to you, but there are still a few which were not addressed, and a couple new items which now appear to need clarification. These are listed below in the order of the application item or exhibit to which they pertain, and identified as to that pertinent part. Items you have responded to and which are not referenced again in this letter are considered at [his time to be adequate. (Please note, while I appreciate the numbered items in the last letter, due to the ordered nature of the application, please identify all responses in your next letter by the exhibit they are intended to address. [request this because your response is not a complete rewriting of the entire application exhibit package. This requested format will allow these follow-up adequacy responses to be more easily integrated into the overall contents of the permit during future review of the permit file, by personnel in our office and possibly yours also.) Application Item 9 -Contact Information The phone numbers shown on the most recently submitted page (received on 10/13/98) aze not current. As noted in my last adequacy review letter, eve must receive a fully updated contact information page. Exhibit B -Site Description Soil resources are not clearly described in your application or in your recent response. In addition to simply naming the soils, please provide their descriptions and a map showing their distribution if necessary. Research of the existing permit file for the Thunderbolt Group (Permit No. M-77-287, of which the Van 4 Shaft site is still a part), contains general information from a 1972 survey, which may or may not still be accurate, but which does not appear to correlate to the soil names you recently submitted. Please clarify. If assistance is needed, you might consider contacting the USDA Natural Resources Conservation Service office in Norwood, phone 970/327-424. Permanent man-made structures were inspected by the Division on l/13/99, and most of them were described to some extent in that inspection report. Your response submittal included a statement about the Division's inspection, but does not provide any additional specific information. There are some details about a few of the listed structures, however, which were not known or noted at the time of the inspection, and were therefore not included as details within the text of that report. Since these were not provided in your response as requested, [his office will use its best estimate when necessary for bond calculation purposes. I must interpret your reference to the Division's report, and absence of specific detail about certain structures in your response, to constitute your acceptance of the Division's measurements, assessments or estimates related to the onsite structures.
