Newest question

Is slash packing on skid trails (or one-pass operations) mandatory, or are there circumstances where multiple passes without slash are acceptable?

Low PSI, wide-track vehicles or one-pass operations (one round trip, in and out) are required for all mechanical harvest operations, including felling and bunching. For multiple passes, equipment must travel on at least 12 inches of slash if equipment exerts more than 6 pounds per square inch, or at least 8 inches if less than 6 psi. In this case, the requirement is written broadly enough that slash mats are not strictly required, as the logging equipment in use qualifies as low PSI and wide-track. Contractors should instead plan for dust abatement: watering haul roads if significant dust is generated from project operations, and possibly leaving or crushing some initial slash to reduce dust on main skid roads.
