Mining areas shall be managed so that watershed modifications are minimized. Runoff from these areas shall be discharged without injury to life, property, and natural resources. Upon deactivation, any runoff from drainage areas altered by mining shall be discharged into receiving waters within the same watershed as existed before mining. When conditions do not allow discharge into the premining watershed, runoff shall be discharged at locations, and in volumes and rates which can be accepted by the receiving waters without injury to life, property, and natural resources.
