Irrigation and Nutrient Management Groundwater Irrigation and Nutrient Management Surface Water

Pesticide Management Surface Water, Groundwater Sediment and Erosion Management Surface Water Riparian Habitat Management Water Quality QUESTIONS: What can growers and the regional board do to ensure that riparian and wetland habitat is protected due to agricultural activities and discharges? How can the regional board use discharge permit requirements to ensure current and future affordable, safe, and clean water for drinking and environmental uses? 4 TABLE 5: RIPARIAN HABITAT MANAGEMENT FOR WATER QUALITY PROTECTION Ag Order 4.0 Updated Option Phasing or Prioritization Prioritization based on location-specific conditions such as beneficial use impairment and high-quality waterbodies. Setback Width and Native Vegetative Cover Quantifiable Milestones* (Numeric Limits) Individual Approach in priority areas Ranch-level setback width and percent native vegetative cover requirements for priority waterbodies are based on stream classification system. Strahler Class Class 1 (ag ditch) Class 2 Class 3 and 4 Class 5 Class 6 Lakes, estuaries, and wetlands Percent Slope 15 - 17% 18 - 20% 21 - 23% 24 - 25% Minimum Setback Width no setback requirement 50 feet with grasses 80 feet with shrubs and grasses 150 feet with trees, shrubs, and grasses 250 feet with diverse trees, shrubs, and grasses 250 feet with diverse trees, shrubs, and grasses Setback Width Adjustment add 10 feet add 30 feet add 50 feet add 60 feet OR Cooperative Approach in priority areas 3P Participate in a Cooperative Watershed Restoration Program (as approved by Executive Officer) AND must have a vegetated setback 1.5 times the width of the waterbody on each side. A Cooperative Approach program may not be approved in certain watersheds if it will result in degradation. Restoration acreage is based upon the setback acreage that would have been required on the

farm under the Individual Approach, at the following mitigation ratios: Waterbody Type Class 2 Class 3 and 4 Class 5 and 6 Lakes, estuaries, and wetlands Ratio 1:1 2:1 3:1 4:1 5 TABLE 5: RIPARIAN HABITAT MANAGEMENT FOR WATER QUALITY PROTECTION Ag Order 4.0 Updated Option Quantifiable Milestones* (Numeric Limits) All other non-priority waterbodies and ranches participating in Cooperative Approach All dischargers with a Class 2 or higher waterbody on or adjacent to their ranch must have a vegetated setback for erosion control that is 1.5 times the width of the waterbody on each side. The presence of bare soil vulnerable to erosion is prohibited for all waterbody classes. No nonnative invasive species may be planted within setbacks. Prohibition The removal of existing native riparian vegetative cover is prohibited, unless authorized through another permitting mechanism. Time Schedule* Setback Width Establishment Setback width establishment date to be determined based on priority areas. Native Vegetative Cover Establishment Native vegetative cover establishment date to be determined based on priority areas. 6 TABLE 5: RIPARIAN HABITAT MANAGEMENT FOR WATER QUALITY PROTECTION Ag Order 4.0 Updated Option Monitoring and Reporting* Riparian Management Reporting Individual Approach a. Buffer width, in feet b. Total native vegetative cover, in percent c. Vegetative cover by type, in percent (trees, shrubs, grasses, non-vegetated) d. Digital map of farm and setback boundaries Cooperative Approach 3P Cooperative program monitors and reports progress annually. Surface Water Quality Trends 3P All ranches must conduct regional bioassessment trend monitoring, either individually or through a cooperative program. -Cooperative Approach may allow for reduced setback and vegetation requirements within the ranch.
