Rimrock Exploration & Development, Inc. <br />J-Bird Uranium Mine/ DMO/ EPP Environmental Protection Plan Description <br />adverse impacts upon the environment are waste rock and ore stockpile(s) also referred to <br />as surface deposition materials. <br />1.1.1 Waste Rock Pile(s) <br />Surface water runoff contacting the waste rock pile(s) will be kept on-site and directed <br />into one of two retention basins. This will be accomplished by engineering and <br />constructing berms designed to keep off-site stormwater from contacting the waste rock <br />pile(s). As well as, capturing or directing meteoric water falling on the permitted site. <br />Excelsior rolls installed and maintained at strategic locations will inhibit sediment <br />transport. Figure 2 details these and other engineered stormwater controls. <br />Representative sampling of the current waste rock pile footprint has recently been <br />completed. Synthetic Precipitation Leaching Procedure (SPLP) tests were conducted of <br />representative waste rock (100ft. due S. vent) material to determine potential for leaching <br />radionuclides and metals. Based on analysis, this material was determined not to have <br />acid generating and minimal toxic leaching potential. Specific details addressing the <br />science behind this conclusion are found in Sections 5 & 14. The raw data for this <br />location is included in Attachment A. Comparative analysis is found in Attachment C. <br />1.1.2 Ore Stockpile <br />The ore stockpile will be constructed following DRMS General Ore Pad Construction <br />Criteria. Surface water runoff contacting the ore stockpile will be kept on-site and <br />directed into a stand-alone retention basin. This will be accomplished by engineering and <br />constructing berms designed to keep off-site stormwater from contacting the ore <br />stockpile. As well as, capture and direct meteoric water falling on the ore stockpile. <br />Excelsior rolls installed and maintained at strategic locations will inhibit sediment <br />transport. For reference, see Figure 2 detailing these and other engineered stormwater <br />controls. Synthetic Precipitation Leaching Procedure (SPLP) tests have been conducted <br />on representative ore stockpile (spot 5-6" deep) material to determine potential for <br />leaching radionuclides and metals. Based on analysis, this material was determined not <br />to have acid generating and minimal toxic leaching potential for Uranium only. <br />Additional details addressing the science behind this conclusion are found in Sections 5 <br />and 14. The raw data for these locations is included in Attachment B. Comparative <br />analysis is found in Attachment C. <br />2
