Section 916.7 - Reduction of Soil Loss

Within the Watercourse and Lake protection zone adjacent to Class I and Class II waters, areas where mineral soil exceeding 800 continuous square feet in size, exposed by Timber Operations, shall be treated for reduction of soil loss. Treatment shall be done prior to October 15th except that such bare areas created after October 15th shall be so treated within 10 days, or as agreed to by the Director. Stabilization measures shall be included and explained in the THP or other required notices. Stabilization measures shall be selected that will prevent significant movement of soil into Class I and II waters and may include, but need not be limited to, mulching, Rip-Rapping, grass seeding, or chemical soil stabilizers.

(a) This section does not apply to the traveled surface of roads. Erosion control measures on road surfaces are specified in 14 CCR § 923.

(b) Where mineral soil has been exposed by Timber Operations on approaches to Watercourse crossings of Class I or II waters, or Class III waters if an ELZ or WLPZ is required, the disturbed area shall be stabilized to the extent necessary to prevent the discharge of soil into Watercourses or Lakes in amounts deleterious to the quality and Beneficial Uses of water.

(c) Where necessary to protect Beneficial Uses of water from Timber Operations, protection measures, such as seeding, mulching, or replanting, shall be specified to retain and improve the natural ability of the ground cover within the standard width of the WLPZ to filter sediment, minimize soil erosion, and stabilize banks of Watercourses and Lakes.
