Eonp <br />Dim sion Director <br />RE: Removal of Tailing from the Hazel-A Adit, Colina Oro Molino,) <br />Inc. (COM, Inc.), Gold Hill Mill, Permit No. M-94-117 <br />The operator is required (letter: Sorenson to Fraser, 10/6/95) to remove <br />tailing slimes from the Hazel-A adit. The adit is to be cleaned "down to <br />intact rock". The 10/6/95 letter specified that the "procedure for the <br />slimes removal operation must be described in detail in a written <br />submittal to the Division, which must be reviewed and approved by the <br />Division prior to initiation of the project". Items which must be <br />included in the operator's proposal are: <br />1. Description of tailing and process water removal method that will <br />assure containment until tailing and water can be redeposited in the <br />pond. <br />2. A statement from the operator that any spillage during the tailing <br />clean-out operation will be immediately contained and removed to the <br />tailing impoundment. <br />3. Detailed procedure for reconstruction of the Hazel-A bulkhead, <br />including provisions for relining the inby face of the bulkhead with <br />hypalon, PVC, or other durable plastic, and for sealing the bulkhead <br />at the interface with the rib. <br />~ 4. A statement from the operator that the Hazel-A adit will be <br />accurately surveyed to determine water storage capacity behind the <br />bulkhead. <br />5. The Division needs to be satisfied that the slimes removal <br />procedures proposed will be adequate to eliminate virtually 100 <br />percent of the tailing material deposited in the adit. <br />COM, Inc. has been notified that the Division will need to receive the <br />written proposal by Wednesday, 11/22/95 if they want to initiate the <br />project by 11/27/95. If the project is underway by 11/27/95. I intend to <br />be on-site to observe the operations. <br />CC: R1C Fanyo C:~WPSI~GOLDHILL.SL2 <br />
