NOV.20.1998 11:38AM DIV/mIPERRLS&GEOLOGY NO. 142 P.4i4 <br /> • MEMORANDUM OF UNDERSTANDING <br /> Department of Health/HMWMD AND The Division of Minerals <br /> October 1992 <br /> Page 2 <br /> the mill takes waste or are from only a single off-site source, the mill still requires a <br /> CO. if a mill ceases taking off-site wastes or ore, the mill may continue operations <br /> under the CD, or may, at its option, apply for a Mined Land Reclamation Board permit <br /> and abandon the CO. It will be up to DMG to notify Health of such action by an <br /> operator. Notification to Health will be via the notice process required for all new <br /> applications and modifications to permits. <br /> 3. HEAP LEACHING OPERATIONS. Facilities conducting heap leaching do not require <br /> a CO, but simply a Mined Land Reclamation Board permit. The DMG will incorporate <br /> SWDFA requirements into the MLRB permit based on comments received from Health <br /> during the normal public comment period. Comments received from Health will be <br /> handled according to established DMG policies and procedures. Those requirements <br /> will be part of the MLRB permit and will be enforceable by DMG. <br /> If a heap leach mining operation imports metallic waste materials from off-site, and the <br /> facility is 'processing, reclaiming, or recycling metallic...wastes.", such activities do not <br /> trigger a CD requirement. If however, the heap leach mining operation also operates <br /> a landfill, then a CD is required. <br /> 4. MINE SITES USED AS LANDFILLS AS A POST MINING LAND USE. If the mine site <br /> landfill accepts off-site waste during the period of active operation and prior to bond <br /> release, a CD is necessary. DMG will condition any new permit application or <br /> modification to an existing permit such that landfill operations may not begin until a CD <br /> has been obtained. Also, where a mine site is to be used as a landfill as a post <br /> mining land use, DMG will contact Health prior to bond release for comment. DMG <br /> will not release the reclamation bond on such a site until an approved CO has been <br /> issued by the appropriate authority. The condition for bond release will be made a <br /> part/of the permit approval document. <br /> e Date <br /> David C. Shelton, Director Michael B.
