<br />Memo to Dave Berry <br />Bowie No. 2 Third Supplemental Response <br />page 2 <br /> <br />presented recommendations for mitigative techniques and methods, including examples. <br />The Division's experience has lead it to realize that it is not practical to specify mitigative <br />techniques for every design situation prior to construction. The regulations reflect this in <br />instances where "as-built" submittals are allowed. In the situation at hand, the Division <br />is satisfied that MAXIM's reports, if all of MAXIM's recommendations are implemented, <br />have demonstrated that the proposed Bowie No. 2 mine plan can be constructed in <br />compliance with the regulations. However, MAXIM's recommendations imply the <br />possibility that a significant number of field redesign situations and mitigative application <br />decisions will occur during the construction effort. In order for the Division to participate <br />in these decisions in a timely fashion, without introducing onerous review requirements <br />and attendant delays, it will be necessary for BRL to communicate these situations on a <br />day-to-day basis. To address this concern, I propose that BRL's qualified geotechnical <br />observers be required to be in attendance whenever construction is occurring and to <br />maintain thorough daily construction log sheets. The qualifications of BRL's qualified <br />geotechnical observers shall be submitted to the Division prior to their commencing <br />observations. In addition, BRL's qualified geotechnical observers shall complete log <br />sheets within 24 hours and deliver them by facsimile to the Division weekly. Further, any <br />cut slope, fill embankment, or drainage facility design modification or mitigative <br />implementation shall be communicated to the Division by telephone or facsimile prior to <br />its implementation. Finally, at the conclusion of construction, BRL shall submit a <br />summary geotechnical construction report to the Division, summarizing the geotechnical <br />problems encountered, and the mitigative methods implemented during the construction." <br />Mr. Stover's January 21, 1997, response complied with all of my above requests, except <br />one. Mr. Stover commited BRL to having a "representative" on site, rather than a <br />"qualified geotechnical observer". This would not have satisfied my concern. During the <br />telephone exchanges of January 28, 1997, both Bili Bear, Jr and Jim Stover indicated <br />that BRL would comply with the Division's request and have a "qualified geotechnical <br />observer' on site during geotechnically sensitive construction operations. Assuming, BRL <br />provides written verification of this commitment, this will satisfy the concern expressed <br />in my January 14th memorandum. <br />(3) Outstanding Unresolved Geotechnical Concerns <br />In my memorandum of January 14th, I also mentioned several of my earlier geotechnical <br />concerns which I believe remain unresolved. In my opinion these remaining items are <br />not conditionable and will continue to prevent the approval of the permit. Mr. Stover <br />responded to each of these concerns, as follows. <br />
