(2) Cuts shall be made sufficiently close to the trunk or parent limb without cutting into the branch collar or leaving a protruding stub;
(3) Proper pruning techniques shall be followed at all times;
(4) Except when directed by the Forest Service, pruning cuts shall be left unpainted for aesthetic reasons;
(5) If the painting of cuts is required, only materials nontoxic to the cambial layer shall be used;

(7) Except when authorized by the Forest Service or when the tree is being removed, climbing hooks or spurs are prohibited;
(8) Chips resulting from roadside tree care may:

(a) Be broadcast on a right-of-way except in ditches, waterways, turf, and surfaced areas, and
(b) Not exceed 6 inches in depth on the right-of-way;

(9) The wrapping or winding of cable, wires, and other attachments around a tree, or fastening attachments to a tree to bruise or injure a tree or cavity work performed on a tree, is prohibited; and
(10) When trees are removed, replacement of those trees according to a plan may be required by the Forest Service.

B. Tree Clearance for Overhead Facilities.

(a) Allow sufficient clearance for 2 years growth normally expected after trimming, unless otherwise directed by the Forest Service;
(b) Take into account the health of the tree; and
(c) Make proper cuts that direct growth away from overhead wires and facilities in compliance with safety standards and government regulations.

(2) If a trimmed tree dies within 1 year or is in poor condition of growth as a result of that trimming, the permittee shall, if required by the Forest Service, remove the tree and plant replacement trees.
(3) Replacement trees shall be:

(a) Furnished by the permittee;
(b) In good condition;
(c) Of a recommended size and species, and
(d) Property planted at locations to be determined by the Forest Service.

C. Ground Disturbance Requirements.

(1) The requirements set forth in this section:

(4) The Forest Service shall supervise the measures taken to protect and repair roadside trees under this section.

D. Protection of Tree Roots.

(1) When an underground project subject to C of this regulation encounters the roots of a roadside tree, a permittee, in accordance with the guidelines in D(2)-(15) of this regulation or other criteria approved by the Forest Service, shall tunnel or bore under the tree continued or modify the project to protect the tree's root system.
(2) For trees under 6 inches in diameter as measured 4 1/2 feet above average ground level, all machine digging shall stop at the dripline of the tree, or where specified by the Forest Service.
(3) For trees over 6 inches in diameter as measured 4 1/2 feet above average ground level, all machine digging shall stop when roots of 1 inch or more in diameter are encountered, or, where specified by the Forest Service.
(4) Roots 1 inch or more in diameter may not be cut without approval of the Forest Service.
(5) A tunnel or other method of modification of the project under or around the tree shall be used if considered necessary by the Forest Service.

(7) At least 24 inches of undisturbed earth shall remain over the tunnel or bore, or above other type of installation.
(8) For operations using shallow trenching techniques up to 12 inches deep, care shall be taken to minimize root damage and protect the trunk of the tree.
(9) Roots 1 inch or larger, damaged during construction, shall be sawed off close to the tree side of the ditch. Clean cuts shall be made at all times.
(10) Installations affecting roadside trees shall be completed in as short a time as possible to prevent the drying out of exposed roots.
