during acceptable ventilation and 

 dispersion conditions. 



• To reduce effects from burning 

 operations : 



- Excavator, landing, and roadwork 

 debris would be piled clean to 

 allow ignition to occur during 

 fall and spring when ventilation 

 is good and surrounding fuels 

 are wet. The Forest Officer may 

 require that piles be covered to 

 reduce dispersed (unentrained) 

 smoke. Covered piles are drier, 

 ignite easier, burn hotter, and 

 extinguish sooner. 



- The number of burn piles would 

 be minimized by leaving large 

 woody debris on site. 



• Dust abatement may be applied on 

 some road segments, depending on 

 the seasonal conditions and level 

 of public traffic. 



SOILS 



> S'O'I Compaction and pisplacement 



• Logging equipment would not 

 operate off forest roads unless 

 soils are adequately dry, frozen 

 to a depth that would support 

 machine operations, or snow 

 covered to a depth that would 

 prevent compaction, rutting, or 

 displacement. 



• Existing skid trails and 

 landings would be used if their 

 design is consistent with 

 prescribed treatments and meets 

 current BMP guidelines. 



• Conventional wheeled and tracked 

 skidders would not be operated 

 on sustained slopes steeper than 

 40 percent, or could be operated 

 on slopes up to 45 percent on a 

 site-specific basis if 

 operations do not cause 

 excessive disturbance. Short 

 steep slopes (less than 300 

 feet) of 40 to 50 percent would 

 be winchline skidded, soft-track 

 yarded, or timber-feller 

 harvested with wood shuttled to 



gentler slopes. 



• The logging foreman and sale 

 administrator would agree to a 

 general skidding plan prior to 

 equipment operations . 



• The density of skid trails in a 

 harvest area would not exceed 20 

 percent of the total area in a 

 cutting unit . 



> ?oi| Erosion 



• Winchline skidding would be 

 required for short (less than 

 300 feet) steep slopes over 45 

 percent, on equipment 

 restriction zones (ERZ) , and as 

 required by the Forest Officer. 



• To reduce surface erosion, roads 

 used by the purchaser would be 

 reshaped and the ditches 

 redefined following use to 

 reduce surface erosion. 



• Drain dips and gravel would be 

 installed on roads, as needed, 

 to improve road drainage and 

 reduce maintenance needs and 

 erosion. 



• Some sections of roads would be 

 repaired to upgrade the roads to 

 design standards that reduce 

 erosion potential and 

 maintenance needs . 



• Certified weed-free grass seed 

 and fertilizer would be applied 

 in a timely manner on all newly 

 constructed road surfaces, cut- 

 and-fill slopes, and any 

 existing disturbed cut-and-fill 

 slopes and landings immediately 

 adjacent to open roads to 

 stabilize soils and reduce/ 

 prevent the establishment of 

 noxious weeds. This would 

 include : 



- seeding all road cuts and 

 fills concurrently with 

 construction; 



- applying "quick cover" seed 

 mix at culvert installation 

 sites within 1 day of when 

 work is completed; and
