• Keep a complete written record and findings of the inspection on the Quarterly Inspection <br />Form (Appendix B); <br />• Attempt to find the cause and evaluate the significance of any unusual conditions noted <br />during the inspection; <br />• Schedule any necessary repairs and maintenance items identified during the inspection <br />and ensure that these are completed; <br />• Obtain the help of a dam safety specialist if unable to confidently assess the significance <br />of any observations made during inspection; and <br />• Keep a written log of repairs and maintenance, including the date and time of inspection, <br />inspector name, description of repair or item, summary of action taken, date of action, <br />and names of persons involved. <br />3.3.2 Special Inspections <br />In addition to the routine quarterly inspections, special inspections will be done during or <br />immediately after the dam or appurtenant diversion systems have been subjected to an unusual <br />occurrence. Unusual occurrences include, but are not limited to an unusually high pool level, <br />significant rainfall event, or an earthquake. The special inspection should focus on the areas <br />potentially affected by the unusual occurrence. An inspection report may or may not be <br />completed, depending on the specific situation, but at minimum a field log report (inspection <br />brief) should be placed in the project files, along with any photographs of the inspection if <br />damage to the dam or appurtenant structures has occurred. More detailed site investigation may <br />be required (such as drilling or surveys) if the special inspection reveals deteriorating dam <br />conditions. <br />4.0 IDENTIFICATION OF DAM - SAFETY RELATED ISSUES AND RESOLUTION <br />4.1. Responsibility <br />The overall responsibility for operating and maintaining the Tailing Facility shall be assigned to <br />a Responsible Party who is a designated employee of BMRI. In addition, one or more additional <br />members of BMRI staff shall be designated as back -up Responsible Party for times when the <br />Responsible Party is on leave or is unavailable. <br />The Responsible Party shall have a basic understanding of engineering principles, and operation <br />and maintenance practices for the tailing facility. Suitable administrative controls and reporting <br />procedures will be implemented by BMRI management to monitor and assist the Responsible <br />Party. Any plans that relate to the tailing facility, such as plans for modifying water management <br />procedures, should be discussed with the Responsible Party so that impacts to the tailing facility <br />can be considered. Copies of this Dam Safety Inspection Program document shall be retained in <br />the office of the Responsible Party. <br />San Luis Project <br />Tailing Dam Safety Inspection and Reporting Program <br />Page 7 of 10 <br />
