Rationale for Proposed Rule Change
GO95 Rule 35
Tree Trimming
Eliminate any confusion between GO95 and the Public Resources Code line clearance requirements for lines located upon mountainous land, or in forest-covered land, brush-covered land, or grass-covered land by incorporating the Public Resources Code line clearance requirements by reference.
The existing rule fails to provide for what the utility should have known with respect to dead, rotten and/or diseased trees. The provisions in Rule 35 should apply when a utility has actual knowledge or should have had such knowledge.
In the existing rule, exception 2 exempts a utility from all of Rule 35's provisions where it has made a "good faith" effort to obtain permission to trim a tree. The exception is vague, and in any event, the outcome of the exception - i.e., exempting a utility from fully complying with Rule 35 is not in the public interest. In order to ensure the public safety, utilities must comply with relevant laws and regulations. Exemption 3 shall be renumbered as 2.
Exception 4 allows the clearance between primary distribution lines and vegetation to be reduced from 18 inches to six inches for the trunks and major limbs of mature trees. Whether or not this exemption may be considered by some to be effective in preventing line-tree contacts causing outages, it does not take into consideration incidents involving children and others climbing trees and tree trimmers working near overhead lines. Eliminating exception 4 will increase the clearance requirement for the trunks and limbs of mature trees to 18 inches and greatly increase safety by reducing the risk of tree climber and tree trimmer line contacts.
Existing Rule
GO95 Rule 35
Tree Trimming
35 Tree Trimming
Where overhead wires pass through trees, safety and reliability of service demand that tree trimming be done in order that the wires may clear branches and foliage by a reasonable distance. The minimum clearances established in Table 1, Case 13, measured between line conductors and vegetation under normal conditions, shall be maintained. (Also see Appendix E for tree trimming guidelines.)
When a utility has actual knowledge, obtained either through normal operating practices or notification to the utility, dead, rotten and diseased trees or portions thereof, that overhang or lean toward, and may fall into a span, should be removed.
Communication and electric supply circuits, energized at 750 volts or less, including their service drops, should be kept clear of limbs and foliage, in new construction and when circuits are reconstructed or repaired, whenever practicable. When a utility has actual knowledge, obtained either through normal operating practices or notification to the utility, that any circuit energized at 750 volts or less shows strain or evidences abrasion from tree contact, the condition shall be corrected by slacking or rearranging the line, trimming the tree or placing mechanical protection on the conductor(s).
EXCEPTIONS:
1. Rule 35 requirements do not apply to conductors, or aerial cables that comply with Rule 57.4-C, energized at less than 60,000 volts, where trimming or removal is not practicable and the conductor is separated from the tree with suitable materials or devices to avoid conductor damage by abrasion and grounding of the circuit through the tree.
2. Rule 35 requirements do not apply where the utility has made a "good faith" effort to obtain permission to trim or remove vegetation but permission was refused or unobtainable. A "good faith" effort shall consist of current documentation of a minimum of an attempted personal contact and a written communication, including documentation of mailing or delivery. However, this does not preclude other action or actions from demonstrating "good faith." If permission to trim or remove vegetation is unobtainable and requirements of exception 2 are met, the utility is not compelled to comply with the requirements of exception 1.
3. The Commission recognizes that unusual circumstances beyond the control of the utility may result in nonconformance with the rules. In such cases, the utility may be directed by the Commission to take prompt remedial action to come into conformance, whether or not the nonconformance gives rise to penalties or is alleged to fall within permitted exceptions or phase-in requirements.
4. Mature trees whose trunks and major limbs are located more than six inches, but less than 18 inches, from primary distribution conductors are exempt from the 18-inch minimum clearance requirement under this rule. The trunks and limbs to which this exemption applies shall only be those of sufficient strength and rigidity to prevent the trunk or limb from encroaching upon the six-inch minimum clearance under reasonably foreseeable local wind and weather conditions. The utility shall bear the risk of determining whether this exemption applies, and the Commission shall have final authority to determine whether the exemption applies in any specific instance, and to order that corrective action be taken in accordance with this rule, if it determines that the exemption does not apply.
