Mr.Cluis Leeseberg December 17,2013 Page 4 of 4 The reclamation plans requires the backfilling of soil from the mining grade to the final contours. An earthwork balance assessment of soil volumes for reclamation must be provided by the applicant to insure that sufficient volumes of soil are maintained onsite to meet the reclamation earthwork needs. The Reclamation Plan indicates future potential roadways. The north-south frontage road in the southern portion of the Site indicates a grade as steep as 20%. The plan should be modified to accommodate a typical roadway grade. The Reclamation Plan does not indicate the specifics related to revegetation of the mined areas. (11) Evidence that access to and use of all haul roads will be safe and that the applicant has received approval by MNDOT for access to and use of state highways,and approval by Sherburne County for access to and use of county roads.Evidence of a right to access and use any private property or easement required to access a public right-of-way or proposed haul road shall also be submitted with the application.Approval to access and use city streets as haul roads shall be at the discretion of the council and will be considered by the council with the application.

(12)Evidence satisfactory to the city that the property proposed to be licensed for mineral excavation does not include any wetlands.If the property does include wetlands,the applicant shall submit,with the application for a mineral excavation license and/or conditional use permit to allow mineral excavation,a wetland delineation map,wetland impact plan,wetland mitigation plan and such other information as is required pursuant to subsection 30-1851(c)of this Code. The information is provided on page 8 of the application. Mining which occurs in the vicinity of the wetland will decrease the drainage area for the wetland,as proposed. There is a potential that the hydraulic characteristics of the wetland will be changed resulting in a change in the related biological conditions. These potential impacts to the wetland should be addressed in accordance with the Minnesota Wetland Conservation Act(WCA). Based on this review,a number of recommended conditions of approval can be developed for the applicant to resolve the deficiencies items identified herein. Please let me know if you would like me to develop these conditions. erely ew L. dvina,P.E.,CHMM Cc: Ken Haberman,Landmark Environmental,LLC
