SAN JOAQUIN COUNTY COMMUNITY DEVELOPMENT DEPARTMENT FILE NUMBER: QX- RECLAMATION PLAN CHECKLIST-CONTINUED [ ] b. flow estimates of watersheds that will be disturbed by or have a potential to impact the proposed mining operation), [ ] 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, [ ] d. an assessment of potential impacts to the ground water regime in the affected area, [ l e. a map showing the relationship between the water table(potentiometric)surface and the proposed mining operation. D. Soil Assessment: If the reclamation plan proposes revegetation, an assessment of existing soil conditions may be appropriate. A soil assessment may include: [ l 1. a topsoil inventory map showing soil salvage depths to assess the volume of topsoil available, [ ] 2. a soil profile description describing soil suitable for reclamation, [ l 3. an analysis of soil texture,chemistry, pH, porosity, permeability, etc., adequate to assess suitability for revegetation. E. Vegetation/WiIdlife: A discussion of existing plant and wildlife species is necessary to assess potential adverse environmental impacts. The discussion may include. [ ] 1. a description of the biological setting (refer to"A Guide to Wildlife Habitats of California"available from the California Department of Forestry and Fire Protection), [ l 2. a map and description of vegetation types of affected areas, [ ] 3. a list of all plants, large and small mammals, birds, amphibians, and fish known or suspected to be on-site(include the date of the survey which can be critical in determining the presence of seasonal species), [ l 4. the identification of unique,critical, and important habitat types within the affected area, [ l 5. a discussion of potential wildlife impacts, short-term and long-term, resulting from the mining operation; [ ] 6. a list of the federal or state designated rare,threatened, or endangered species,or State Fish and Game species of special concern (including invertebrates),if any, on or near the site. F. In-stream Mining: If mining will occur within an active stream channel,any or all of the following information may be needed to assess impacts of the proposed operation: [ ] 1. evidence of contact with local flood control agency regarding possible permitting requirements, [ l 2. identify other in-stream mining operations within five miles of the project site, (this information should be used by the lead agency in assessing the cumulative impact of mining on the river channel). [ ] 3. identify bridges, pipelines,cable crossings, etc.within one mile of the proposed operation, [ l 4. show premining configuration of gravel bar/stream bed on map or aerial photograph, [ ] 5. provide cross section(s)of premining stream conditions which can be used to monitor future impacts of the mining operation. [ ] 6. discuss seasonal flow conditions and gravel replenishment rates, 7. discuss Wild and Scenic River status, \DEVSVC\Planning Application Forms\ Page$ of 19 carry Excavation.doc.(Revised 02-03-10)
