4 3503 MINING AND GEOLOGY TITLE 14 (p• 100) (Register e5,No.76-4485) shall consider the physical and land-use characteristics of the mined lands and their surrounding area pursuant to Public Resources Code Section 2773. NOTE:Authority cited: Section 2755, Public Resources Code. Reference: Sections 2712(a)-(c),2756-2757,2770 and 2772-2773,Public Resources Code. HISTORY: 1. Renumbering and amendment of former Section 3502 to Section 3501, and new Section 3502 filed 4-29-85;effective thirtieth day thereafter(Register 85,No.18).For prior history,see Registers 82,No.33 and 79, No.35. 3503. Surface Mining and Reclamation Practice. The following are minimum acceptable practices to be followed in surface mining operations: (a) Soil Erosion Control. (1) The removal of vegetation and overburden,if any,in advance of surface mining shall be kept to the minimum. (2) Stockpiles of overburden and minerals shall be managed to minimize water and wind erosion. (3) Erosion control facilities such as retarding basins, ditches, streambank stabilization,and diking shall be constructed and maintained where necessary to control erosion. (b) Water Quality and Watershed Control. (1) Settling ponds or basins shall be constructed to prevent potential sedi- mentation of streams at operations where they will provide a significant benefit to water quality. (2) Operations shall be conducted to substantially prevent siltation of ground-water recharge areas. (c) Protection of Fish and Wildlife Habitat. All reasonable measures shall be taken to protect the habitat of fish and wildlife. (d) Disposal of Mine Waste Rock and Overburden. Permanent piles or dumps of mine waste rock and overburden shall be stable and shall not restrict the natural drainage without suitable provisions for diversion. (e) Erosion and Drainage. Grading and revegetation shall be designed to minimize erosion and to convey surface runoff to natural drainage courses or interior basins designed for water storage. Basins that will store water during periods of surface runoff shall be designed to prevent erosion of spillways when these basins have outlet to lower ground. (f) Resoiling. When the reclamation plan calls for resoiling, coarse hard mine waste shall be leveled and covered with a layer of finer material or weathered waste. A soil layer shall then be placed on this prepared surface. Surface mines that did not salvage soil during their initial operations shall attempt,where feasible,to upgrade remaining materials.The use of soil condi- tioners,mulches,or imported topsoil shall be considered where revegetation is part of the reclamation plan and where such measures appear necessary. It is not justified, however, to denude adjacent areas of their soil, for any such denuded areas must in turn be reclaimed. (g) Revegetation. When the reclamation plan calls for revegetation the available research addressing revegetation methods and the selection of species having pod survival characteristics, for the topography, resoiling characteris- tics, and climate of the mined areas shall be used.
