mineral acid, heavy metals and sediment. Diversion measures will be addressed in the BMP <br />section following. It is also possible that spills of waste rock may occur when loading trucks. <br />This will also be addressed in the BW section. The impacted area is 1.208 acres. <br />The material is then transported to Venture Resources' I Iukill Gulch Millsite where it is unloaded <br />into a sheltered, concrete pad next to the milling operations. This pad has been engineered to <br />isolate the material from weather events. This destination is already covered under WCQD Permit <br /># COR040255. <br />• Outdoor Storage of Chemicals or Equipment: <br />As part of operations, there will be a rubber-tired loader, an excavator, and dump trucks (1-2) on- <br />site. BMP's addressing this will follow. There are no outdoor washing facilities. <br />There will be no outdoor storage of any chemicals at this site. <br />• Outdoor Milling or Processing Activities: <br />No processing/milling activities will be done at this site. <br />• Historic Mine Drainage: <br />On the approximately 1,000 tons of pre-existing, historic and abandoned waste rock that covers <br />this impacted site there is stotmwater run-off. Water samples are included in the appendix of this <br />SWMP to describe a "before" state. BMP's for this area have been developed. <br />There are no additional sources of historic mine drainage from any tunnels, adits, or other mine <br />workings in the permit boundaries. <br />• Tailings Ponds: <br />No tailings ponds or impoundments are proposed at this site. <br />• Crushing Facilities: <br />No crushing, screening or processing will be done at this site. <br />• On-site Waste Disposal: <br />There will be rather insignificant generation of rubbish waste associated with routine work habits <br />of upto 3 part-time employees. A 55 gal. drum fitted with a lid and trash bag liner will be located <br />outside for trash collection. BMP's will address trash maintenance. <br />• Stockpiles of Overburden, Raw Material, Intermediate Products, Byproducts, Finished <br />Products, or Waste Products: <br />o Overburden: Within the Affected Area (see Section 3 maps) there is a staging area to <br />stockpile salvaged topsoil for future reclamation measures that are prescribed in the <br />DRMS mining permit application. BMP's will follow to address this area. <br />o Raw Material: The material to be removed was addressed above in the Loading and <br />Unloading Operatations. <br />o Intermediate Products: none, no processing on this site. <br />o Byproducts: none, no processing on this site. <br />o Finished Products: none, no processing on this site. <br />o Waste Products: none, no processing on this site. <br />Description of Best Management Practices (BMP's) <br />The most significant source of potential stormwater contamination results from the pre-existing, historic <br />and abandoned waste rock on site. This has been a problem for well over 100 years. This operation will <br />be removing pollutant point sources and processing it offsite in a carefully regulated manner. <br />Page 3 of 9
