COVCC does believe that it has failed to implement <br />repair of the west portal cut failure in accordance with approved <br />Minor Revision 62. In fact, COVCC has initiated repair in accor- <br />ance with MR62, as noted in CMLRD`s past three inspections and in <br />COVCC's progress report to CMLRD, dated February 7, 1990. However, <br />work at this site has not been completed. No deadline for comple- <br />tion of the work was identified in MR62 or required by CMLRD. <br />COVCC has proceded in good faith and kept CMLRD informed of it's <br />progress. As noted in the COVCC progress report of February 7, <br />1990, initial work on the site has been completed. Subsequently, <br />and prior to final completion of the work, COVCC contracted with <br />Mr. Michal Bukovansky of CH2M Hill (who designed the repair ac- <br />cepted by CMLRD in MR62) to evaluate the initial work. His evalua- <br />tion shows that the existing cut configuration is only slightly <br />steeper than that recommended. Furthermore, he has specifically <br />recommended that further excavations or cut modifications be <br />delayed until after the 1990 spring and summer season. This will <br />allow for the necessary time to evaluate the stability of the <br />current slopes. Any additional modification at this time does not <br />assure any greater stability. A copy of his report of <br />investigation and observations is attached. <br />MINED LAf~O <br />RECLgA/ATIRN DIVISION <br />
