Steve O'Brian Page 4 of 5 April 25, 2014 The existing exposed groundwater lake in the eastern area must be bonded for in some fashion. Bond may be calculated for the installation of a slurry wall to isolate it from the surrounding alluvial aquifer (see paragraph above for slurry wall calculation). Bond for that area may also be determined using a defensible determination of cost for the placement of the amount of fill required to backfill the existing exposed groundwater area to no more than 6.1 acres of exposed groundwater, with the rest of the area backfilled to a level at least two feet above the existing documented static water level. The backfilled areas must then be appropriately sloped and seeded. Areas to be re- sloped, otherwise re- graded, re- soiled, and reseeded should be shown on the provided reclamation plan map. EXHIBIT N - Source of Legal Right to Enter (Rule 6.4.14): The exhibit submitted was mislabeled as Exhibit H, but otherwise adequate. EXHIBIT S - Permanent Man -Made Structures (Rule 6.4.19): As previously discussed, structure agreements will need to be obtained for all structures within 200 feet of the permit boundary. Please note that roadways and above - ground or underground utilities (if present) within 200 feet of the proposed affected area are considered permanent man -made structures. In accordance with Rule 6.4.19, when mining operations will adversely affect the stability of any significant, valuable and permanent man -made structure located within 200 feet of the affected area, the applicant may either: a.) Provide a notarized agreement between the applicant and the person(s) having an interest in the structure, that the applicant is to provide compensation for any damage to the structure; or b.) Where such an agreement cannot be reached, the applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining operation. c.) where such structure is a utility, the Applicant may supply a notarized letter, on utility letterhead, from the owner(s) of the utility that the mining and reclamation activities, as proposed, will have "no negative effect" on their utility Please provide evidence (certified letter to structure owners) that a notarized agreement between the structure owners and the applicant was pursued. If an agreement is unable to be reached a geotechnical assessment may be provided to demonstrate that the structures shall not be damaged. You must provide information sufficient to demonstrate that the stability of any structures located within two hundred (200) feet of the operation or affected land will not be adversely affected. Additional Information: You will also need to provide the Division with proof of notice publication and proof of notice to surrounding property owners within 200 feet. Any letters from other commenting agencies /entities received by the Division to date have been included with this correspondence for you to review. This concludes the Division's preliminary adequacy review of this application. This letter shall not be construed to mean that there are no other technical deficiencies in your application. Other issues may arise
