<br />Division of Minerals and Geology <br />19 November 1998 <br />Page 2 <br />r~ <br />3. CAMAS agrees to coordinate a proposed construction schedule with I)MG so that <br />foundation preparation and outlet drain construction may be viewed in the field and <br />DMG can inspect these critical design features prior to being covered by Zone B fill <br />as requested. Because construction of the engineered fill is a site activity that must be <br />scheduled around production activities that are the company's primary responsibility, <br />CAMAS proposes a notification procedure whereby CAMAS commits to notification <br />to DMG that certain foundation and drain elements are ready for inspection and DMG <br />commits to visit the site to inspect them within a reasonable period of time so that fill <br />slope construction may proceed without interfering with other site activities. We <br />propose to discuss these with you prior to Tk approval and have mutually acceptable <br />conditions written by DMG as stipulations to TR approval. <br />CAMAS agrees to the requested additional shear strength testing of the proposed <br />"Jade Air Fines" (JAF)/structural fill mixtures that will comprise the Zone B fill. <br />CAMAS only requests that this testing not be required to be completed prior to TR <br />approval. Rather we propose that the testing be done and submitted for review by <br />DMG as quickly as possible, but that conditional TR approval proceed so that <br />foundation preparation and filter installation work may proceed in the meantime. <br />CAMAS and Haley & Aldrich appreciate the responsiveness of DMG in reviewing Technical <br />Revision TR-02 for the Morrison Quarry. If you have any questions regarding this response <br />to your questions and comments from the original TR-02 submittal, or if you need any <br />additional information, please contact either Mike Refer or me. <br />Sincerely, <br />HALEY & ALDRICH~,AINC.~ <br />~'°v `~ <br />Alan L.
