Inventories and equipment inspections: the programs beyond the cycle
Four different records get called an inventory or an equipment inspection on a vegetation contract, and they have four different owners. A continuing plant inventory record has five federally specified fields under 18 CFR Part 101. A vegetation inventory has none specified anywhere, so the contract that buys it writes the schema.
Take one wood pole on a 12 kV distribution circuit, and call it pole 214. By the end of a normal year that pole appears in four separate records held by the same utility.
An accounting record naming what it cost and the year it went into service.
An inspection record naming who looked at it and what they found.
A vegetation record naming the trees around it and what was prescribed.
A driver's report from whoever parked a truck under it that morning.
Each of those has a different owner inside the company, a different content standard, and a different retention period. Three of the four are specified in writing by somebody outside the utility. The fourth is specified by whoever drafted the contract, and that fourth one is what a vegetation program is usually buying when a scope line says inventory.
Four records name the same pole, and four rules
The word inventory does a lot of work on a vegetation contract, and so does the phrase equipment inspection. Both name more than one thing. Sorting them before the walk starts is cheaper than sorting them in an audit.
Record | What one row is | What specifies the row | Who owns it |
Continuing plant inventory record | A retirement unit, or a category of mass property | 18 CFR Part 101, Definitions, item 8 | The utility's accounting function |
Distribution inspection record | An inspection of a circuit, area, facility or equipment | The utility's asset inspection program | |
Vegetation inventory | A stem, worked or not | The contract, and nothing above it | Usually the contractor's application |
Driver vehicle inspection report | One vehicle, one work day | The motor carrier |
Two further programs sit alongside these and have their own pages. Pole clearing runs off a list of poles rather than a list of trees, and which poles are subject poles under PRC 4292 is the question that builds that list. On transmission, FAC-003-5 sets an annual vegetation inspection obligation on applicable lines, and the two clocks that obligation runs are separate from anything here.
The failure this page exists to head off is one workforce producing one file and a scope line treating it as all four.
The plant record has five fields, and none is condition
The Uniform System of Accounts defines the utility's asset inventory at item 8 of its Definitions, and the definition is a list of fields:
A. For each retirement unit: (1) The name or description of the unit, or both; (2) The location of the unit; (3) The date the unit was placed in service; (4) The cost of the unit as set forth in Plant Instructions 2 and 3 of this part; and (5) The plant control account to which the cost of the unit is charged
Five fields, and four of them are about money or time. Pole 214 is a 45 foot class 4 western red cedar set in 1974. The continuing plant inventory record carries its 1974 installed cost and the account that cost was charged to. It has nothing to say about the split that opened in its crossarm sometime after 2019.
That matters to a vegetation program manager for one practical reason. A request to the asset system for the condition of the poles on a circuit is a request a cost record was never built to answer. Condition lives in the inspection file, and the inspection types that file is written against set what condition information exists at all.
Mass property is where a pole stops being its own row
The same definition has a second branch, and it is the one that catches people out:
B. For each category of mass property: (1) A general description of the property and quantity; (2) The quantity placed in service by vintage year; (3) The average cost as set forth in Plant Instructions 2 and 3 of this part; and (4) The plant control account to which the costs are charged.
A quantity and a vintage year. Where a utility carries its poles as mass property rather than as individual retirement units, the accounting record holds 1,180 poles placed in service in 1974 at an average cost. Pole 214 is inside that number and is not addressable from it.
So the identifier a vegetation inventory hangs its rows on comes from the operational asset system, which is a different system with a different history and different accuracy. Whose entry counts as the record when two systems disagree is worth settling in writing before a row is written against either.
An inventory row carries a fact, a unit carries a prescription
A crew works units. An inventory holds rows, and a row is a statement about a stem on a date, whether or not anyone will ever touch it. The unit a crew can work without a phone call is a different product built from different fields.
Nothing in the California stack specifies those fields, so the contract does. A row that a second inspector can re-find and a third can re-use carries:
The structure or span it hangs on, in the identifier the utility's asset system issues.
A coordinate, with how it was captured and the accuracy claimed for it.
Species, diameter at breast height, and height.
The distance to the nearest energized conductor, and which conductor that is.
Condition, scored against the scale the contract names.
The date of the observation and the person who made it.
Whether the stem was worked, and under which work order if it was.
The concrete case is the row that produces no work. A 26 inch coast live oak standing 38 feet off the nearest phase, recorded on March 4, 2026, generates no prescription and appears in no work record. It is also the row the inventory was bought for. A file containing only stems that needed cutting is a work list wearing an inventory's name.
The denominator is the deliverable, and a partial walk breaks it
An inventory gets bought because somebody upstream needs a number. How many stems, of what species, at what distance from the conductor, on how many circuit miles. That number lands in a budget, a filing, or a growth model.
Forty-one circuit miles inventoried at full census yields 1,140 stems, of which 212 carry a prescription this cycle. Three years later the same circuit yields 318 prescriptions. Against 1,140 the prescription rate moved from 19 percent of the stems to 28 percent. Against 212 the same pair of numbers reads as a 50 percent jump in workload. The base is what makes the second number mean anything, and species growth rate against a cycle length is the calculation the base exists to feed.
Two disciplines protect that base. The first is stating the population walked, span by span, including the spans that produced nothing. The second is the date, because a row is a claim about a stem at a moment. When a sample is defensible in place of a census is a question with a real methodology behind it, and a partial walk with no sampling plan is not that answer.
What a vegetation inspector may write down about the hardware
GO 165 says a patrol inspection "may be carried out in the course of other company business," and what that sentence does and does not permit is settled elsewhere. The practical fact is that a vegetation inspector is already standing under the pole with a camera.
At 9:40 on a Tuesday, working span 213 to 214, the inspector photographs a split in the crossarm. Three things follow, and only the first happens by itself.
The photograph and its coordinates land in the vegetation file, because that is the application open on the tablet. Whether the same observation also discharges any part of a GO 165 patrol is decided by the utility's own inspection procedure, not by the vegetation contract and not by the inspector. And the condition itself, once identified, is a GO 95 nonconformance or a Safety Hazard on the utility's own facility, which puts its correction under Rule 18A and the record standard that closure has to meet.
The entry has to say which of those it is. An observation filed as a vegetation note, with no path to the hardware program, is a photograph nobody acted on and a date somebody will later read against a failure.
Rule 18B counts ten business days from the discovery
The case that bites hardest is hardware belonging to somebody else. General Order 95 Rule 18 defines a Safety Hazard as "a condition that poses a significant threat to human life or property," and Rule 18B then sets what happens when one company's inspection finds one on another company's plant:
If a company, while performing inspections of its facilities, discovers a safety hazard(s) on or near a communications facility or electric facility involving another company, the inspecting company shall notify the other company and/or facility owner of such safety hazard(s) no later than 10 business days after the discovery. To the extent the inspecting company cannot determine the facility owner/operator, it shall contact the pole owner(s), who shall be responsible for promptly notifying the company owning/operating the facility with the safety hazard(s), normally not to exceed five business days after being notified of the safety hazard. The notification shall be documented and such documentation must be preserved by all parties for at least ten years.
Read the trigger. The period runs from the discovery, which happened in the field on Tuesday morning, and not from the day the inspector's entry was synced, reviewed or exported. A vegetation program that batches field data weekly has spent part of the ten days before anyone at the utility has seen the finding.
Rule 18B also tells the pole owner what it must be able to do. The note under it requires that each pole owner be able to determine all other pole owners on poles it owns, and all authorized entities attached to its portion of a pole. That is the lookup an inspector needs on the day, and the vegetation obligations that follow a shared pole are a separate question from who gets the notice.
One word is doing heavy lifting here and the order leaves it open. Rule 18A(1)(a) addresses "each company (including utilities and CIPs)." Section II of GO 95, its definitions section, runs from Rule 20.0 Antenna to Rule 24.3 Working Space and defines 44 terms, among them Pole, Practicable and Thoroughfare.
Company is not among the 44. A contractor's inspector performing the utility's vegetation pre-inspection is either the inspecting company or the eyes of one, and the order does not say which. The utility's procedure and the contract that flows it down supply the answer, and the instruments that establish who an inspector represents are where it is written.
The rule has also moved four times, which matters to any flow-down that quotes it:
Date | Instrument |
August 20, 2009 | Added by Decision No. 09-08-029 |
January 12, 2012 | Revised by Decision No. 12-01-032 |
December 21, 2017 | Revised by Decision No. 17-12-024 |
May 31, 2018 | Revised by Decision No. 18-05-042 |
A subcontract exhibit that reproduces Rule 18 should say which text it reproduces and on what date it was pulled.
Equipment inspection also names the truck, and weight decides
The third meaning of the phrase is the fleet, and a prequalification questionnaire rarely says which meaning it wants. The federal line is a number. 49 CFR 390.5 reaches a vehicle used on a highway in interstate commerce with a gross vehicle weight rating or gross combination weight rating of "4,536 kg (10,001 pounds) or more," and 49 CFR 396.11(a)(1) then requires this of every such vehicle:
Every motor carrier shall require its drivers to report, and every driver shall prepare a report in writing at the completion of each day's work on each vehicle operated
The report covers eleven named systems, from service brakes to emergency equipment, and FMCSA's own form is the shape a field app is usually imitating. Section 396.11(c) puts the report, the certification of repairs and the certification of the driver's review on a three month clock. 49 CFR 396.17 adds the annual layer, barring use of a commercial motor vehicle unless every component in appendix A "has passed an inspection ... at least once during the preceding 12 months and documentation of such inspection is on the vehicle."
California applies the same two federal sections to its own carriers. 13 CCR 1215(b) requires that "all drivers shall perform vehicle inspections and submit written reports in accordance with the requirements of Title 49, Code of Federal Regulations, Sections 396.11 and 396.13," and subdivision (c) repeats the same eleven systems.
Which vehicles the CHP reaches is set by Vehicle Code section 34500, amended most recently by Statutes of 2024, Chapter 226, effective January 1, 2025. Subdivision (a) takes motortrucks of three or more axles above 10,000 pounds. Subdivision (k) takes commercial motor vehicles at 26,001 pounds or more. Subdivision (j) sweeps in "any other motortruck regulated by ... the United States Secretary of Transportation," which is where a two-axle truck at 10,001 pounds running interstate comes back in.
Run those against a real fleet. A 33,000 pound chip truck is inside subdivision (k) on any trip. A two-axle inspection pickup at 8,600 pounds gross vehicle weight rating, working intrastate, sits outside (a), outside (k) and outside 390.5.
Where a prime's flow-down requires a daily written report on that pickup, the requirement is real and its source is the contract. Saying so in the bid is better than discovering in an audit that the program has been producing federal-format reports on vehicles no federal rule reaches, or that it has been producing none on vehicles two rules do.
Settling which record a scope line is buying
Four records also means four retention clocks, and the shortest one is the likeliest to set a platform's default. A driver's report is held three months under 49 CFR 396.11(c). A patrol or detailed inspection record is held "at least ten (10) years" under GO 165 Section III.C, and an intrusive inspection record for "the life of the pole."
A Rule 18B notice is held ten years by every party to it. Which clock each artifact in a California vegetation file runs on decides what the system must still be able to produce years later, and it is a separate question from what any of the records contains.
Before the first row is written, five things are worth naming in the document rather than in a kickoff call.
Which of the four records the deliverable is, named by its governing instrument rather than by the word inventory.
The identifier every row hangs on, and which system issues it when the accounting record carries poles as mass property.
Whether stems that generate no work get a row, and how the population walked is recorded.
What happens to a hardware observation made on a vegetation trip, who it routes to, and who starts the ten business days when the plant belongs to somebody else.
Which vehicles the daily report covers, and whether 49 CFR 396.11, 13 CCR 1215 or the contract is the reason.
None of the five is expensive to answer in advance. All five are expensive to reconstruct from a finished file.

Frequently asked questions
Does any rule say what a utility tree inventory has to contain?
No California or federal rule does. Two neighboring records are specified in detail. Item 8 of the Definitions in 18 CFR Part 101 sets five fields for each retirement unit in a continuing plant inventory record, and CPUC General Order 165 Section III.C sets the contents of a distribution inspection record. Neither reaches a tree. The fields in a vegetation inventory come from the contract that buys it, which means the scope of work is the only place a missing field can be caught before the walk starts.
What is a continuing plant inventory record, and does it say what condition a pole is in?
It is the utility's plant record for retirement units and mass property, defined at item 8 of the Definitions in 18 CFR Part 101. For each retirement unit it carries the name or description, the location, the date placed in service, the cost as set out in Plant Instructions 2 and 3, and the plant control account the cost is charged to. Condition is absent from that list. It is a cost record, and the condition of the pole lives in the inspection file GO 165 Section III.C governs.
A vegetation inspector sees a cracked crossarm on a pole owned by somebody else. What does the code require?
CPUC General Order 95 Rule 18B requires the inspecting company to notify the other company or facility owner no later than 10 business days after the discovery. Where the owner cannot be determined, the pole owner is contacted and is responsible for notifying the operator, normally within five business days. The notification must be documented and the documentation preserved by all parties for at least ten years. The clock runs from the discovery in the field, not from the day the entry is uploaded.
Is an inspection pickup covered by the daily driver vehicle inspection report?
It depends on weight and on who regulates the trip. 49 CFR 390.5 reaches a vehicle at 10,001 pounds gross vehicle weight rating or more used on a highway in interstate commerce, and 49 CFR 396.11 requires a written report at the completion of each day's work on each such vehicle. In California, Vehicle Code section 34500 sends the CHP after motortrucks of three or more axles above 10,000 pounds and commercial motor vehicles at 26,001 pounds or more. A two-axle pickup at 8,600 pounds running intrastate falls outside both. Where a prime requires a daily report on it anyway, that requirement is contractual.
