11. Section 6.3.3(1)(c) of the application appears to utilize the terms "waste rock" and "tailings" to <br />describe the same materials. Waste rock is large particle waste materials generated from the <br />driving of adits and shafts as necessary to access the ore body. Tailings are small particle waste <br />materials, from the ore body, resulting from the milling process after the mineral values have been <br />extracted. Please maintain this distinction throughout all portions of the application. <br />12. Section 6.3.3(1)(c) states, "No more that 5,000 cubic yards of non acid producing ore will be stored <br />on the Mayday No.1 bench...." Please note that such statements, in the approved permit, may <br />become enforceable permit conditions. <br />13. Section 6.3.3(1)(c) of AM-01 states, "No more than 25,000 tons of rock will be sampled or <br />developed from the No. 2 portal ... " Pursuant to,Rule 1.1(27), all 110(2) operations are restricted <br />to producing less than 70,000 tons of mineral, overburden, or combination thereof per calendar <br />year. This limitation on production applies to the entire site, each year. When providing <br />information on production, please specify tonnages of mineral (ore) and overburden (waste rock), <br />or clarify that the quantity includes both mineral and overburden and represents total production. <br />14. Section 6.3.3(1)(c) of AM=01 states, "Ventilation has been approved by the Mine and. Safety and <br />Health Administration and will be implemented in accordance with MSHA criteria and guidelines." <br />As noted previously, please show the underground openings for the ventilation facilities on the <br />maps and discuss these openings in the text. <br />15. Section 6.3.3(1)(f) of AM-01 states, "All areas of disturbances are pre-existing. Approximately 3 <br />acres of the permit area have been disturbed as a result of previously milling and mining activities <br />(Exhibit E-2)." Pursuant to Rules 6.3.3(1) and 6.3.5(2)(f), please outline and label these existing- <br />disturbances on the appropriate maps. <br />16. Please clarify the contradiction between Section 6.3.3(1)(f), which indicates that the three acre <br />area of existing disturbances will not be enlarged, and Section 6.3.3(1)(e), which states that the <br />exiting bench at Level 2 will be extended. Please specify the dimension of the extended bench at <br />Level 2 as required by Rule 6.3.3(1)(f). <br />17. Section 6.3.3(1)(h) of AM-01 states, "The water source will be from the water that is present in the <br />underground workings at the Mayday-Idaho Mining complex and from the Idaho augmentation <br />ponds..." Please indentify all locations underground where such water sources exist. Additionally, <br />please clarify whether ground water will be pumped from these underground water sources and if <br />so, please describe and illustrate how this will occur. <br />18. The requirements of Rules 6.3.3(1)(i), 3.1.6, 3.1.7, 6.3.3(1)(k), 6.3.3(1)(1), and 6.3.3(1)(m) are not <br />fully addressed. Please provide the information requested in the attached memo from the <br />Division's Geochemist, David gird. <br />4
