C. The following
requirements apply to timber harvesting within all management and protection
subdistricts except as otherwise mentioned above or hereinafter provided:
1. Except when surface waters are frozen,
skid trails and skid roads must not utilize stream channels bordered by a P-SL1
subdistrict except to cross such channels with a culvert or bridge according to
the water crossing requirements of Section 5(C)(4) and (7)
2. Skid trails, skid roads, and winter haul
roads in P-RR subdistricts established to protect a trail or flowing water and
P-RT subdistricts must follow the shortest practicable route in traversing such
subdistrict and traverse such subdistrict the fewest number of times
practicable.
3. Skid trails, skid
roads, and winter haul roads in P-RR subdistricts around a body of standing
water must be discontinued, gated, obstructed, or otherwise made impassable to
two wheel drive vehicles upon completion of timber harvesting, provided that,
wherever such approval is legally required, the Maine Forest Service approves
discontinuation of such road, which approval the owner must request.
4. Timber harvesting in P-SL1, P-GP, P-GP2,
and P-RR subdistricts must be conducted in the following manner:
a. Within 50 feet of the normal high water
line, no clearcutting is allowed and harvesting operations must be conducted in
such a manner that a well-distributed stand of trees is retained so as to
maintain the aesthetic and recreational value and water quality of the area and
to reasonably avoid sedimentation of surface waters.
b. At distances greater than 50 feet from the
normal high water line, harvesting activities may not create single openings
greater than 14,000 square feet in the forest canopy. In such areas, single
canopy openings of over 10,000 square feet must be no closer than 100 feet
apart.
c. Harvesting must not
remove, in any ten year period, more than 40 percent of the volume on each acre
involved of trees 6 inches in diameter and larger measured at 4 1/2 feet above
ground level. Removal of trees less than 6 inches in diameter, measured as
above, is permitted if otherwise in conformance with these regulations. For the
purposes of these standards, volume may be determined as being equivalent to
basal area.
d. No accumulation of
slash must be left within 50 feet of the normal high water line of surface
water protected by the P-SL1 and P-GP subdistricts. In such subdistricts, at
distances greater than 50 feet from the normal high water line of such waters,
all slash larger than 3 inches in diameter must be disposed of in such a manner
that no part thereof extends more than 4 feet above the ground.
5. Timber harvesting in P-FW
subdistricts must be conducted in the following manner:
a. The landowner or designated agent must
confer with the appropriate biologist at the Department of Inland Fisheries and
Wildlife as to how the proposed activity is to occur within the P-FW
subdistrict.
b. If a plan
acceptable to the parties cannot be reached stating how the proposed activity
should occur, the landowner or designated agent is required to obtain a permit
from the Bureau. The applicant for such permit must show by a preponderance of
the evidence that the proposed activity will be conducted in a manner which
produces no undue adverse impact upon the resources and uses in the
area;
c. If a plan acceptable to
the parties can be reached, the landowner or designated agent must notify the
Bureau in writing with a copy of the field investigation report by the
biologist that states how and over what time period the activity is to occur.
The notification letter must be signed by the person responsible for the
proposed activity and the field investigation report must be signed by the
biologist;
d. The landowner or
designated agent may proceed with activity in conformity with the plan 14 days
after the notification to the Bureau unless within such time period the Bureau
disapproves the plan; and
e. The
landowner or designated agent must notify the Bureau of completion of activity
so that a follow-up field investigation may be carried out by the Bureau or its
designee.
6. Timber
harvesting in a P-RR subdistrict established to protect a flowing water must be
carried out in compliance with the standards for timber harvesting in P-SL1
subdistricts as set forth in this section.
7. Except as provided in Section 4(B)(9),
skid trails and other sites, where the operation of machinery used in timber
harvesting results in the exposure of mineral soil, must be located such that
an unscarified filter strip of at least the width indicated below is retained
between the exposed mineral soil and the normal high water line of surface
water areas:

Table 4-1. Unscarified filter strip width requirements for
exposed mineral soil created by the operation of machinery used in timber
harvesting.
The provisions of this subsection apply only on a face
sloping toward the water, provided however, no portion of such exposed mineral
soil on a back face shall be closer than 25 feet. The provisions of this
subsection do not apply where skid roads cross such waters.
8. Timber harvesting operations must be
conducted in such a manner that slash is not left below the normal high water
line of a body of standing water or tidal waters, or below the normal high
water line of stream channels downstream from the point where such channels
drain 300 acres or more.
9. Except
when surface waters are frozen, skid trails and skid roads must not utilize
stream channels bordered by P-SL2 subdistricts except to cross the same by the
shortest possible route. Unless culverts or bridges are installed in accordance
with Section 5(C)(4)and (7), such crossings must only use channel beds which
are composed of gravel, rock or a similar hard surface which would not be
eroded or otherwise damaged. The requirements of this subsection may be
modified according to the provisions of Section 4(B)(9).
10. Except as provided in Section 4(B)(9),
skid trail and skid road approaches to stream channels must be located and
designed so as to divert water runoff from the trail or road in order to
prevent such runoff from directly entering the stream.
11. Timber harvesting operations in P-SL2
subdistricts along stream channels upstream from the point where they drain 300
acres or less, and in P-WL subdistricts adjacent to such P-SL2 subdistricts,
may be conducted in a manner not in conformity with the requirements of the
foregoing Sections 4(B)(5),(8)and (9)provided that such operations are
conducted so as to avoid the occurrence of sedimentation of water in excess of
25 Jackson Turbidity Units as measurable at the point where such stream channel
drains 1 square mile or more. Jackson Turbidity Units are a standard
measurement of the relative amount of light that will pass through a sample of
water compared with the amount of light that will pass through a reference
suspension; the Jackson Turbidity Unit measurement for water without turbidity
is 0;
12. Harvesting operations in
P-SL2 subdistricts along stream channels downstream from the point where they
drain 300 acres or more and along bodies of standing water must be conducted in
such a manner that sufficient vegetation is retained to maintain shading of the
surface waters; and
13. In addition
to the foregoing minimum requirements, except as provided for in Section
4(B)(9), provision must be made to conduct timber harvesting operations to
reasonably avoid sedimentation of surface waters.
14. In addition to the preceding standards,
timber harvesting in proximity to an existing development must also comply with
the applicable requirements of Chapter 10 of the Commission's Rules and
Standards, Land Use Districts and Standards, Section 10(27)(B), "Vegetation
Clearing. "For purposes of this provision, "in proximity to an existing
development" means the following:
a. For a
lot developed with a single family dwelling unit with shoreline frontage on any
body of standing water ten acres or greater, or a flowing water draining 50
square miles or more, the area within a rectangle measuring 200 feet along the
shoreline centered on the primary structure by 250 feet perpendicular to the
shoreline measured from the normal high water line of the waterbody.
b. For a lot developed with a single family
dwelling unit with shoreline frontage on a standing body of water less than ten
acres in size, or any tidal water, or flowing water draining less than 50
square miles, the area within a rectangle measuring 150 feet along the
shoreline centered on the primary structure by 75 feet perpendicular to the
shoreline measured from the normal high water line of the waterbody.
c. For a lot developed with a single family
dwelling unit with road frontage on a public road, the area within a rectangle
measuring 100 feet along the road right-of-way or similar boundary of the road
centered on the primary structure by 50 feet perpendicular to the roadway
measured from the edge of the road right-of-way.
d. For a commercially developed lot or lot
developed with multiple structures located parallel to a water body with
shoreline frontage on any body of standing water ten acres or greater, or a
flowing water draining 50 square miles or more, the area within a rectangle
measured from 50 feet from each end of the development along the shoreline and
250 feet perpendicular to the shoreline measured from the normal high water
line.
e. For a commercially
developed lot or lot with multiple structures located parallel to a water body
with shoreline frontage on a standing body of water less than ten acres in
size, or any tidal water, or flowing water draining less than 50 square miles,
the area within a rectangle measured from 50 feet from each end of development
along the shoreline and 75 feet perpendicular to the shoreline measured from
the normal high water line.
f. For
a commercially developed lot or lot developed with multiple structures located
parallel to and with frontage on a public road, the area within a rectangle
measured from 50 feet from each end of development along the road right-of-way
or similar boundary of the road and 50 feet perpendicular to the roadway
measured from the edge of the road right-of-way.
