TERMINOLOGY

Treatment Method Felling, Bucking and Limbing Specifications

Pile Cut material (slash) smaller than 6 inches in large end (diameter outside bark) and 10 feet long shall be hand piled.

Piles shall be compact, and free of soil to facilitate burning, and shall be constructed of such a size and at such a distance from trees so that burning shall not result in unnecessary damage to residual timber

The Contractor shall construct a fire line cleared to mineral soil and at least 3 feet wide around each pile. In areas where there is potential for burning material to roll, firelines shall be trenched on the downhill side of each pile to adequately prevent material from crossing firelines.

Trenches shall be constructed by hand unless otherwise agreed.

Chip Material up to 8 inches shall be chipped.

Chips shall be scattered into openings away from and without unnecessary damage to residual trees or infrastructure.

Chip depth shall be no greater than 6 inches deep. When chipping is specified, another method may be used by agreement.

Lop and Scatter Slash shall be scattered to reduce slash concentrations with slash being generally left no more than 18 inches deep on the ground. Slash shall be scattered into openings away from and without unnecessary damage to residual trees.

All scattered logs shall be limbed, placed away from trees and positioned so they will not roll. When scattering is specified, another method may be used by agreement.

Treatment of Stumps Within areas shown on the contract map, contractor shall treat stumps of all live conifer trees equal to or greater than 14 inches stump diameter, (measured inside bark) unless otherwise agreed to in writing. Treatment shall be with a borate compound registered by EPA in the State of California for prevention of annosus root disease. Treatment shall consist of removal of sawdust and other loose debris from the cut surface of the stump and applications of a thin layer of the borate compound uniformly over the entire cut surface, including exposed wood surfaces on the stump sides, at the rate specified on the product label. Any surface irregularities on the stump preventing application of a uniform layer of borate compound shall be cut level prior to treatment. Unless waived in writing, contractor shall also apply an approved colorant mixed with the borate compound to insure complete coverage.

Treatment should be done as soon as possible but shall be completed no later than 24 hours after felling, otherwise stumps shall be re-cut and treated.

Contractor shall not apply borate compound during rain fall or when such precipitation rate is predicted within 24 hours of application to cause borate compound to be flushed off the stump and become ineffective, in that case treatment shall be reapplied. Application shall be completed within 24 hours of the precipitation having ceased. Borate compound also shall not be applied to stumps located within 20 feet of live stream courses and meadow/wetlands shown on the Contract Map.

Contractor shall submit at the end of each month a “Monthly Summary of Pesticide Use Report” to the appropriate County Agricultural Commissioner with a copy to the District Ranger.
