Mr. Guth <br />December 2, 2014 <br />Page 4 of 5 <br />Where will the five new monitoring wells proposed for the Ditullio Property be located? Can these wells be <br />installed and measured prior to additional dewatering activity to establish background conditions? What will the <br />monitoring frequency be for monitoring water levels in the site wells? What deviation from "historic levels" <br />would trigger increased monitoring/mitigation and reporting to DRMS? DRMS views the "trigger levels" as a <br />level at which increased measures to monitor for off -site impacts should be undertaken (impacts outside the <br />normal expected range of variation are being observed). Typical examples of this would include increased <br />monitoring frequency or addition of additional monitoring points. They may not, in themselves require immediate <br />corrective actions, although DRMS fully encourages operators to be proactive in avoiding negative off -site <br />impacts. <br />In the event that an adverse off -site impact is observed or reported, it is not up to the permittee /operator to <br />determine cause or responsibility. DRMS and/or the MLRB will make that determination, as well as what, if any, <br />corrective actions are required to mitigate the observed impact. The permittee /operator will be required to provide <br />any required monitoring data and any other potentially useful data (pumping dates, rates, etc.) to DRMS to help <br />make that determination. Therefore it is obviously in the operator /permittee's best interest to collect and maintain <br />as much data as possible (including pre- mining background conditions) to determine what, if any, effects to the <br />"prevailing hydrologic balance" have resulted from activity at the site. <br />EXHIBIT L - Reclamation Costs (Rule 6.4.12): <br />All information necessary to calculate the costs of reclamation must be submitted and broken down into the <br />various major phases of reclamation. You must provide sufficient information to calculate the cost of <br />reclamation that would be incurred by the state. <br />The task breakdown seems reasonable. Several tasks appear to have been omitted, for example, the re- <br />spreading and grading of topsoil and preparation for seeding, and the maintenance and weed control of the <br />vegetated areas after seeding and prior to release of the Ditullio parcel, (commonly at least 2 growing <br />seasons), as well as the as -built survey for that area. It may also be useful to correlate the acreage data/tasks <br />in the table to the phases of a reclamation plan map for clarity. <br />The seed costs also appear very low, but DRMS can supply a per -acre cost using the seed mix provided in <br />AM -01. <br />EXHIBIT S - Permanent Man -Made Structures (Rule 6.4.19): <br />Please note that roadways and above -ground or underground utilities (if present) within 200 feet of the <br />proposed affected area are considered permanent man -made structures. In accordance with Rule 6.4.19, when <br />mining operations will adversely affect the stability of any significant, valuable and permanent man -made <br />structure located within 200 feet of the affected area, the applicant may either: <br />(a) Provide a notarized agreement between the applicant and the person(s) having an interest in the <br />structure, that the applicant is to provide compensation for any damage to the structure; or <br />(b) Where such an agreement cannot be reached, the applicant shall provide an appropriate engineering <br />evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining <br />operation; or <br />(c) Where such structure is a utility, the Applicant may supply a notarized letter, on utility letterhead, from <br />the owner(s) of the utility that the mining and reclamation activities, as proposed, will have "no negative <br />effect" on their utility. <br />
