Wash. Admin. Code § 222-30-060 - Cable yarding
Current through Register Vol. 22-07, April 1, 2022
(1)*Type S
and F Waters and sensitive sites. No timber shall be cable yarded in or
across Type S or F Waters except where the logs will not materially damage the
bed of waters, banks of sensitive sites, or riparian management zones. If
yarding across Type S or F Waters is permitted, then yarding is limited to
cable or other aerial logging methods. Any work in or above Type S or F Waters
requires an approved forest practices application. Logs must be fully suspended
above the water unless otherwise allowed in the applicable forest practices
application. Yarding corridors or full suspension shall be required to prevent
damage to the bed, banks, and riparian vegetation. Yarding corridors must be no
wider or more numerous than necessary to accommodate safe and efficient
transport of logs. Generally, yarding corridors should be located no closer to
each other than one hundred fifty feet (measured edge to edge) and should be no
wider than thirty feet. Safety is a prime consideration in the location of
yarding corridors. Total openings resulting from yarding corridors must not
exceed twenty percent of the stream length associated with the forest practices
application. When changing cable locations, care must be taken to move cables
around or clear of the riparian vegetation to avoid damage to riparian
vegetation.
Trees, logs, limbs, and other small debris that enter the water shall be managed as follows:
(a) Trees
or logs that enter Type S and F Waters with identifiable bed or banks during
yarding shall remain where they enter unless parts or all of the trees or logs
are specifically approved to be removed by the department.
(b) Logs transported across Type S or F
Waters shall be suspended so no portion of the logs or limbs can enter the
watercourse or damage the bed and banks.
(c) If limbs or other small debris enter Type
S or F Waters with identifiable bed or banks as a result of yarding timber,
they shall be removed concurrently with each change in yarding road or within
seventy-two hours after entry and placed on stable locations outside the
stream's influence. Limbs or other small debris shall be removed from dry
portions of watercourses prior to the normal onset of high flows. Large woody
material that was in place prior to yarding of timber shall not be disturbed.
(2)
Type A or B
Wetlands. No timber shall be cable yarded in or across Type A or B
Wetlands except with approval by the department .
(3)
Deadfalls. Logs which are
firmly embedded in the bed or bank of Type S or F Waters shall not be removed
or disturbed except with approval by the department.
(4)
Yarding in riparian management
zones, sensitive sites, and wetland management zones. Where timber is
yarded from or across a riparian management zone, sensitive site, or wetland
management zone reasonable care shall be taken to minimize damage to the
vegetation providing shade to the stream or open water areas and to minimize
disturbance to understory vegetation, stumps and root systems. Where practical
and consistent with good safety practices, logs shall be yarded in the
direction in which they lie and away from Type A or B Wetlands or Type S, F or
Np Waters until clear of the wetland management zone or riparian management
zone.
(5)
Precautions shall
be taken to minimize the release of sediment to waters downstream from
the yarding activity. See board manual section 5 for technical
guidance.
(6)
Direction of
yarding.
(a) Uphill yarding is
preferred.
(b) Where downhill
yarding is used, reasonable care shall be taken to lift the leading end of the
log to minimize downhill movement of slash and soils.
(c) When yarding parallel to a Type S or F
Water channel below the 100-year flood level or within the riparian management
zone, reasonable care shall be taken to minimize soil disturbance and to
prevent logs from rolling into the stream, lake, pond, or riparian management
zone.
(7)
Disturbance avoidance for northern spotted owls. The operation of
heavy equipment within a SOSEA boundary shall not be allowed within 0.25 mile
of a northern spotted owl site center between March 1st and August 31st
provided that, this restriction shall not apply if:
(a) The landowner demonstrates that the owls
are not actively nesting during the current nesting season; or
(b) The forest practice is operating in
compliance with a plan or agreement developed for the protection of the
northern spotted owl under WAC
222-16-080(6)(a), (e), or
(f).
(8)
Disturbance avoidance for marbled
murrelets. Yarding or operation of heavy equipment shall not be allowed
within 0.25 mile of an occupied marbled murrelet site during the daily peak
activity periods within the critical nesting season, provided that, this
restriction shall not apply if the forest practice is operating in compliance
with a plan or agreement developed for the protection of the marbled mur-relet
under WAC
222-16-080(6)(a) or
(c).
