BEST MANAGEMENT PRACTICES TO BE INCORPORATED WITH THIS PROJECT

BMPs as described in the “National Best Management Practices for Water Quality Management on National Forest System Lands” have been effective in protecting beneficial uses. Visual field surveys have indicated that these BMPs, where properly implemented, have adequately protected and minimized the impacts to acceptable levels. Past deficiencies in the implementation of these BMPs have been the cause for the erosion problems associated to roads and skid trails.

The purpose of this set of Best Management Practices (BMPs) is to avoid, minimize, or mitigate adverse effects to soil, water quality, and in-stream riparian resources that may result from road management activities. Road management activities include travel route planning, design, construction, operation, maintenance, reconstruction, storage, and decommissioning.

Other transportation-system-related activities include stream and waterbody crossings, snow removal, parking areas, and equipment refueling and servicing areas.

• Road-5. Temporary Roads

Objective Avoid, minimize, or mitigate adverse effects to soil, water quality, and riparian resources from the construction and use of temporary roads.

• Road-7. Stream Crossings

Objective Avoid, minimize, or mitigate adverse effects to soil, water quality, and riparian resources when constructing, reconstructing, or maintaining temporary and permanent waterbody crossings.

• Road-9. Parking and Staging Areas

Objective Avoid, minimize, or mitigate adverse effects to soil, water quality, and riparian resources when constructing and maintaining parking and staging areas.

• Road-10. Equipment Refueling and Servicing

Objective Avoid or minimize adverse effects to soil, water quality, and riparian resources from fuels, lubri- cants, cleaners, and other harmful materials discharging into nearby surface waters or infiltrating through soils to contaminate groundwater resources during equipment refueling and servicing activities.

• WatUses-3. Administrative Water Developments

Objective Avoid, minimize, or mitigate adverse effects to soil, water quality, and riparian resources when developing and operating water sources for Forest Service administrative and resource management purposes.

Note: Please refer to the “National Best Management Practices for Water Quality Management on National Forest System Lands” April 2012, for full description of the BMPs listed above.
