3. Apply dust oils only when the roadbed has been properly graded, 



watered, shaped and compacted. Construction of a temporary 

 small berm or wrinkle made on the downside road shoulder will 

 assist in preventing the material from running off the road 

 during application. 



4. Oil should be shut off when crossing all streams. 



5. In lieu of salts for ice and snow control, snow plowing, chains 

 and sanding should be utilized where possible and appropriate. 

 The use of salt-sand mixtures should also be promoted in lieu of 

 straight salt applications. 



6. The use of salt for snow and ice control on logging roads should be 

 limited to minimum essential needs. This would include limiting 

 salt application to those areas necessary to provide a safe 

 driving surface (i.e., steep grades, major intersections and 



stop points). 



7. Avoid application of de-icers near streams or lakes. 



8. Locate storage areas where the threat to groundwater and surface 

 water contamination is minimal. 



G. Road Closure 



Many roads, especially work roads associated with timber harvesting, are 

 designed for use only for a short time. These roads should be closed 

 along with any other roads that are needed only for intermittent 

 travel to minimize maintenance expense and erosion hazards. 



1. Block the road to vehicles. 



2. Remove all temporary culverts including brush and wood types. 



3. Remove all temporary bridges. 



4. Remove all other culverts and bridges that cannot be maintained. 



5. Except on large fill slopes, outslope the road surface and remove 

 all berms, taking care not to spill graded material over the fill
