Mr. Ragsdale <br /> October 11,2019 <br /> Page 2 of 3 <br /> of the pit to form angle-of-repose slopes along the pit walls. Could you please clarify the difference between <br /> these two waste placement methods? Perhaps a simple diagram or two illustrating the differences would be <br /> useful. Please elaborate/provide additional detail for the statement that"new material will be placed in lifts as <br /> originally planned." <br /> EXHIBIT E -Reclamation Plan (Rule 6.4.5): The approved/stated post-mining land use for this permit is <br /> primarily rangeland, with an industrial/commercial area of approximately 33 acres where the current processing <br /> facility is located. DRMS will require that the permittee demonstrate that the water quality in the proposed 10 <br /> acre pond(area currently used for process water) meets the appropriate surface water standards for a livestock <br /> pond prior to final release. Please acknowledge. <br /> Please specify what buildings will remain in the process area after reclamation and what buildings will be <br /> removed, and make this clear on the reclamation map. Stating that unnecessary industrial buildings and <br /> equipment will be removed does not provide sufficient detail for the calculation of that portion of the reclamation <br /> bond. <br /> EXHIBIT F - Reclamation Plan Map (Rule 6.4.6): Please show what buildings will remain at final reclamation <br /> within the processing area. <br /> EXHIBIT G-Water Information (Rule 6.4.7): DRMS has reviewed the additional information provided in the <br /> adequacy response, and verified that SEO has not required a well permit or substitute water supply plan for this <br /> operation as they have determined that it does not expose groundwater. DRMS concurs that monitoring of <br /> groundwater quantity/quality outside of the pit is not warranted at this time. DRMS encourages the permittee to <br /> address the water rights issues identified in the adequacy response as soon as practically possible. <br /> EXHIBIT L-Reclamation Costs (Rule 6.4.12): All information necessary to calculate the costs of reclamation <br /> must be submitted and broken down into the various major phases of reclamation. You must provide sufficient <br /> information to calculate the cost of reclamation that would be incurred by the state. <br /> Please resubmit this exhibit-considerably more information and details will be required for this exhibit to meet <br /> the requirements of Exhibit L as listed above. It is sometimes useful to think of this exhibit as"what information <br /> would I need to provide to a third-party to get a complete bid to conduct all the work required". Costs should be <br /> broken down by task and acreage area, and preferably shown on the reclamation plan map or map dedicated to <br /> this exhibit. Details such as topsoil and overburden volumes, equipment to be used,push distances, specifics for <br /> demolition and disposal costs for removal of the"red-mix"plant area, etc. will need to be provided. As an <br /> example some information that will be required is listed below: <br /> 1) How many acres will be reseeded by drill seeder(pit floor,plant area,quarry perimeter) and how many acres <br /> will require broadcast/hydro-tack compound(pit slopes). <br /> 2) How many cubic yards of backfill material will need to be placed/moved to achieve 2.5:1 slopes on all the pit <br /> walls? You may use the current conditions for this estimate. <br />
