DRMS considered the access road's capacity to handle a 40 -ton vehicle (the review did <br />not include specific vehicle types or purposes such as sanitation, concrete, or excavation). Since <br />the access road design is based on a maximum vehicle load of 40 tons, vehicles with weights <br />greater than 40 tons are not permitted to utilize the access road. Again, the DRMS review of the <br />access road was to ensure that the road is stable and usable for support of a small scale <br />underground mining operation. <br />DRMS review related to the existing mine roads under CN -01: <br />The pre - existing roads within the permitted area pre -dated the permit application. <br />Therefore, the pre- existing roads did not receive a rigorous review from DRMS because the <br />plans submitted by Wildcat did not propose activities that would require significant upgrades or <br />improvements be made to these roads. Rather, DRMS reviewed a proposed plan related to a <br />small underground mine and intended uses of the existing roads in support of that specific <br />mining operation. As explained below, the small scale and nature of this operation inherently <br />dictates the size of the equipment that will be necessary to support the operation. <br />Sanitary facilities /trucks are not typically an issue specifically reviewed by DRMS. <br />Operators are expected to do their own site maintenance /cleaning and hauling of trash offsite. <br />Trucks utilized for sanitation purposes could be approved under a proposed plan so long as they <br />are compliant with the weight limits, turning radius, and grades of the existing and historic mine <br />roads. <br />Additionally, DRMS did not specifically consider large concrete trucks use of the roads. <br />However, such a review was not warranted based on the proposed plans submitted and reviewed <br />by DRMS. Small underground mines, such as the May Day Idaho Complex, generally mix their <br />concrete on -site with a mobile mixer. This type of concrete mixer is towed behind a pick -up <br />truck. The existing roads will support this type of activity. <br />By "excavation truck" it is assumed that you are referring to highway haul trucks. Again, <br />this is a small underground operation. Waste rock generated from mining operations has been <br />proposed to be disposed underground or dumped nearby the portal. The application (not yet <br />approved) proposes to mill and concentrate ore materials on -site with on -site disposal of <br />tailings. The primary commodity proposed to be exported from the site is concentrate, which is <br />typically shipped in 55 gallon drums, which can be transported from the mill to the County Road <br />by pick -up truck. The proposed plan did not include movement of large quantities of earthen <br />materials across the surface nor did the plan indicate a need for large excavation trucks. <br />As we discussed yesterday, Wildcat received a conditional approval from the Mined <br />Land Reclamation Board for plans proposed under CN- 01(attached). Under the terms of the <br />conditional approval Wildcat cannot commence mining and milling activities at this site until it <br />submits and receives the necessary approvals from DRMS related to, among other things, <br />detailed works plans, mining plans, water quality information, and design specifications related <br />to Environmental Protection Facilities. Based on the future permitting activities required under <br />CN -01 the DRMS may need to reevaluate the stability of the pre - existing roads dependent upon <br />plans submitted by Wildcat. The DRMS welcomes comments from the County related to any <br />2 <br />
