Identifying and addressing pertinent issues in the preparation stage will minimize delays later on i I the approval process. The determination of which issues should he addressed in the reclamation plan for a specific site should be based on the size of the proposed operation, its potential environmental impacts, and the proposed end use of the site. Those items marked with an"X"are required by specific statutory language. Other items should not be considered as mandatory but may be required by the County, depending on site specific circumstances. More or less information maybe required,depending on the specific operation,agency requirements,and local ordinances. Check with Development Services staff to determine which items should be included. [XI I.

The lead agency will use the information provided in this section to identify potential adverse environmental impacts of the proposed mining operation. A. Maps Site Access: Provide a road map which clearly shows how to get to the site from the nearest town. IXI Topographic Map z: This map is necessary to establish the location and regional setting of the mine site. The map should portray elevation contours, natural ground slopes,drainage patterns, and other topographic features of the mine site and its surrounding region within one mile of the mine site. Use U. S. Geological Survey 7-%z or 15 minute maps, which are the most accurate and useful. B. Geology': (X] 1. Provide a description of the general geology of the area and a detailed description of the area in which mining is to be conducted. The information will be used to assess potential adverse environmental impacts. Specifically,the geologic description should include: I ) a. A description of geologic setting. I I b. Geologic cross section(s)in the location of proposed slopes,dams,tailings facilities, etc. adequate to assess potential stability problems. I I c. Any other geological information requested by the administering agency. C. Hydrology: 1. Describe surface and ground water resources. The description may include: I i a. Evidence of contact with the State Water Resources Control Board and the Regional Water Quality Control Board regarding possible permitting requirements(most of the concerns relating to the discharge of mine waste can be satisfied by appending the report of waste discharge and waste discharge permit to the reclamation plan). I ) b. Flow estimates of watersheds that will be disturbed by or have a potential to impact the proposed mining operation). I i c. A description of land and water uses in affected watersheds that may be impacted by the proposed mining operation including a hydrologic inventory of wells and springs in affected areas. I 1 d. An assessment of potential impacts to the ground water regime in the affected area. I J e. A map showing the relationship between the water table(potentiometric)surface and the proposed mining operation.
