Who enforces what: CPUC, CAL FIRE, NERC and the utility
Updated: Sep 21
Four bodies reach a California vegetation finding and none enforces another's rule. The CPUC audits and cites under GO 95 and GO 165. Energy Safety issues notices of violation against an approved wildfire mitigation plan. CAL FIRE inspects, and the exposure behind its findings is a misdemeanor under PRC 4021. WECC enforces FAC-003 against registered functions.
Turlock Irrigation District has been on the receiving end of two of the four, fifteen years apart.
On November 13, 2009, NERC filed a Notice of Penalty at FERC proposing an $80,000 settlement between the district and the Western Electricity Coordinating Council, one item of which was a vegetation violation on a 230 kV line. On June 4, 2024, the CPUC's Safety and Enforcement Division sent the district an audit report, EA2024-1181, itemizing violations of General Orders 95 and 128 and asking for a written response by July 2.
Footnote 2 of the first document reads: "As a public power utility, TID is not subject to regulation or oversight by the California Public Utilities Commission (CPUC)." Both documents are accurate. What sits between them is the whole subject of this page, which is that jurisdiction in California vegetation work is not one thing that a body either has or lacks. It is four separate grants, each attaching to a different object, each producing a different instrument, and none of them enforcing another's rule.
The authority each body actually has
Body | What it enforces | What attaches the duty | The instrument it issues |
CPUC, Safety and Enforcement Division | GO 95, GO 128, GO 165, GO 174 and the Public Utilities Code | Commission jurisdiction over the company | Audit report, citation, order instituting investigation |
Office of Energy Infrastructure Safety | An approved wildfire mitigation plan, and guidelines within its authority | Being an electrical corporation with a plan on file | Notice of Violation, and referral to the CPUC |
CAL FIRE | PRC 4291 through 4299 and Title 14 Article 4 | Land cover and a determination of necessity | Inspection report on form LE-38a, nuisance abatement, referral for prosecution |
NERC and WECC | FAC-003 and the rest of the Reliability Standards | Registration for a function on the NERC Compliance Registry | Notice of Penalty filed at FERC, settlement agreement, mitigation plan |
The utility | Its own maintenance program, specifications and contracts | Ownership of the facility | Work order, correction due date, contract remedy |
Read the third column rather than the first. None of these bodies acquires authority over a span because the span is dangerous. The CPUC's reach follows the company, not the acre. CAL FIRE's follows what grows on the ground and a determination that the statutes are necessary there. NERC's follows a registration that has nothing to do with either. A single conductor can be inside all four at once and can also be inside exactly one.
The negatives are worth stating as plainly as the grants, because most of the wasted effort in this subject comes from expecting the wrong body to act.
CAL FIRE does not enforce GO 95. Page 63 of the California Power Line Fire Prevention Field Guide says so outright, telling protection agency personnel to learn the General Order and then disclaiming any enforcement responsibility for it, leaving them to observe and report infractions to the utility.
The CPUC does not enforce PRC 4292 or 4293; those are statutes in the Public Resources Code, with their own numbers and their own measurement conditions, and no Commission decision reaches them. FAC-003 belongs to neither of them, and the Compliance Enforcement Authority that does hold it has no view on a General Order. Energy Safety does not measure a Table 1 clearance; it measures what the utility promised in its plan.
The CPUC audits, and the audit is not the citation
Two very different documents come out of the same division, and treating them as one thing is the most common error in this area.
The audit is a records review and a field check that ends in a letter. Turlock's ran March 18 to 22, 2024, and Rickey Tse, a Program and Project Supervisor in the Electric Safety and Reliability Branch, signed the transmittal on June 4. The letter asks the district for "a response no later than July 2, 2024, via electronic copy of all corrective actions and preventive measures taken by TID to correct the identified violations and prevent the recurrence of such violations."
It states that the branch will post both the report and the response on the CPUC website. There is no penalty in it, no accrual, and no appeal. What staff asked for before anyone walked a circuit, and what the findings looked like on the page, is its own subject.
The citation is the other instrument, and it is the one that carries money. The Commission adopted an electric safety citation program in Decision 14-12-001 in December 2014, modified it in D.15-05-054 in May 2015, and adopted improvements in D.16-09-055 in September 2016. Under it, staff issue a citation directly rather than opening a formal proceeding first. Vegetation is not a theoretical use of it.
On April 25, 2017, the Commission issued PG&E citation E20150916-01 arising from the Butte Fire, which carried $8,000,000 for a violation of GO 95 Rule 31.1 and a separate $300,000 for GO 95 Rule 35 and Resolution E-4184. The statutory exposure behind those numbers, per offense and per day, sits in Public Utilities Code sections 2107 and 2108.
Three mechanics of a citation decide how a vegetation finding actually behaves once one is issued, and the Commission prints them on the face of the document. From SED's December 19, 2025 citation to Southern California Edison, W.25-12-001:
Payment of a citation or filing a Notice of Appeal does not excuse the Respondent from curing the violation. The amount of the penalty may continue to accrue until a Notice of Appeal is filed. Penalties are stayed during the appeal process.
Paying does not close the condition. The meter runs until an appeal is filed, not until the check clears. And the same citation requires that violations which are not immediate safety hazards be corrected within 30 days of service.
The alternative is a Compliance Plan the utility submits to the Director of SED inside the same 30 days, supported by a declaration from its Chief Executive Officer or an appropriate designee. A clearance finding that a program intends to fold into the next cycle becomes, once cited, a document signed at the top of the company.
One more CPUC route exists and is easy to miss because it lives in a different branch. SED's Wildfire Safety Enforcement Branch issues citations under Resolution WSEB-1, on its own schedule of specified violations and scheduled fines, and W.25-12-001 above is one of those.
The Electric Safety and Reliability Branch and the Wildfire Safety Enforcement Branch look at overlapping systems under different instruments, and a self-report that satisfies one has not necessarily reached the other. When one utility found that its inspection system and its field results disagreed, it reported to SED on April 25, 2023 and to Energy Safety ten days later, which is the practical answer to how many envelopes a disclosure takes.
A publicly owned utility is inside GO 95 and outside the citation program
This is where NERC's footnote and the CPUC's audit stop contradicting each other.
The Commission has no economic regulation of a municipal utility or an irrigation district. It does have safety jurisdiction over their overhead and underground electric facilities, and the grant is narrow and specific. Public Utilities Code section 8037 provides that the Commission
may grant such additional time and shall inspect all work which is included in the provisions of this article, and may make such further additions or changes as the commission deems necessary for the purpose of safety to employees and the general public,
and closes with one sentence:
The commission shall enforce the provisions of this article.
Section 8056 carries the same language for the parallel article, and section 8002 supplies the scope. Read together, those sections put a publicly owned utility inside GO 95, GO 128 and GO 165 for safety purposes and nowhere else.
That is why SED audits irrigation districts and municipal systems on the same forms it uses for an investor-owned utility, and why the audit file for a single reporting year holds filings from Modesto Irrigation District, Roseville, Lompoc and Silicon Valley Power beside PG&E's.
What does not travel is the citation. The electric safety citation program adopted in D.14-12-001 is directed at electrical corporations. So for a district, the audit letter, the corrective-action response and the public posting are the enforcement, and the arithmetic of a missed correction date is available to anyone who reads the file rather than to a citation clerk. For an electrical corporation the same finding can end at a dollar figure with a per-day multiplier behind it.
The consequence for a contractor or a prime working across both kinds of client is that the same field defect has two different half-lives. On a district's system it becomes a line in a published report that stays visible against the program's name. On an investor-owned system it becomes a number and a correction clock signed by an officer.
Energy Safety enforces the plan, not the clearance
The body most programs are surprised by is the newest one. The Office of Energy Infrastructure Safety, inside the Natural Resources Agency, is the successor to the CPUC's Wildfire Safety Division and has been vested with its duties since July 1, 2021. It approves each electrical corporation's wildfire mitigation plan, and then it goes out and checks whether the work in the plan was done.
An example, in full detail, because the detail is the point. On December 19, 2023 an Energy Safety inspector, identified in the report only as CAC15, inspected SCE's WMP initiatives near Beaumont in Riverside County, selected from the utility's own Quarter 2 Quarterly Data Report. On April 19, 2024, Patrick Doherty, a Program Manager in the Compliance Assurance Division, issued a Notice of Violation to SCE's Vice President for Asset Management and Wildfire Safety. The violation table has seven columns:
Violation | Structure ID | HFTD | Initiative | Type | Severity | Description |
1 | 1248323E | Tier 2 | 8.2.3.3.1 Expanded Clearance | Adherence to Protocol | Minor | Failure to achieve required clearance |
The finding: near pole 1248323E at 38390 Vineland Street, Beaumont, at 33.9724233305095, -116.992083439283, "the inspector observed that vegetation was growing within four feet of the distribution lines." The relevant requirement quoted against it is not Table 1 and not the Public Resources Code. It is SCE's own plan text, that within its High Fire Risk Area "SCE's Routine Line Clearing work within HFRA maintains at least the required four feet clearance for Distribution lines."
Three things follow from that, and they generalize.
The measure is the utility's own commitment. The severity reasoning says so explicitly: the violation is Minor because SCE's clearance work "was identified as complete at this location," the tree is in the High Fire Risk Area, and the tree is "within SCE's required four feet of clearance." A program that writes an aspirational number into a filed plan has written an enforceable one.
The clocks are Energy Safety's own, and they are not GO 95's. The agency's compliance guidelines set correction timelines by risk category.
Risk category | Correction timeline |
Severe | Immediate resolution |
Moderate, in High Fire-Threat District Tier 3 | Two months |
Moderate, in Tier 2 | Six months |
Moderate, relevant to worker safety and not in Tier 3 | Six months |
Minor | Twelve months, or resolution scheduled in the WMP update |
Those are different periods from the ones a Level 2 GO 95 nonconformance runs on, set by a different body against a different document, and the tier that selects the row is the same tier in both.
The process has its own statutory scaffolding. The NOV is issued under Public Utilities Code section 326 and Government Code section 15475.1, and identifies noncompliance with an approved WMP "or any law, regulation, or guideline within the authority of the Office," per 14 CCR 29302(b)(2).
The corporation has 30 days to describe corrective actions or to state that it will not correct the violation, with reasoning and supporting documentation. A hearing must be requested inside the same 30 days, and if it is not, "the determination and conditions set forth in this NOV become final." The NOVs cite Government Code section 15475.4 for the hearing step; SB 254 repealed that section effective September 19, 2025.
Then the handoff, in the NOV's own words:
Pursuant to Public Utilities Code section 8389(g), following receipt of the electrical corporation's response to this NOV and resolution of any disputes, this matter may be referred to the California Public Utilities Commission for its consideration of potential enforcement action, as it deems appropriate.
Energy Safety writes findings. The Commission is where they can turn into money.
A publicly owned utility is outside this route as well. Under Public Utilities Code section 8387, a local publicly owned electric utility or electrical cooperative prepares its own wildfire mitigation plan and contracts with a qualified independent evaluator to assess its comprehensiveness. After January 1, 2026, it submits that plan to the California Wildfire Safety Advisory Board at least once every four years, on a schedule that board sets. There is no approval by Energy Safety and no Notice of Violation at the end of it.
CAL FIRE inspects, documents, and hands the finding somewhere else
The Department's enforcement grant is old, broad on its face, and narrower in effect than the wording suggests. PRC 4119 puts enforcement of the state forest and fire laws on the Director or a duly authorized agent, with a right of inspection over every property but the inside of a dwelling.
That second phrase is doing more work than it looks like: by interagency agreement the agent standing at a pole with a tape may be a federal land management employee or a county firefighter rather than anyone on CAL FIRE's payroll. Within the Department, power line work sits with the Office of the State Fire Marshal's Utility Wildfire Mitigation program, created in 2018 by SB 1028 and SB 901, which supports power line inspections and enforcement of PRC 4292 and 4293.
What that inspector produces is a document, not a penalty. Form LE-38a captures the finding and a copy goes to the utility that owns the infrastructure inspected; what a notice on that form obliges, and the specificity the guide holds it to, is set out with the firebreak statute. For a conductor clearance the same guide instructs agency personnel not to measure physically because of the electrocution risk, which means the two state findings on one span arrive in different units of measure before either one is filed anywhere.
Behind that document sit three routes, and none of them is an administrative fine the Department writes itself.
The first is criminal. PRC 4021 makes it a misdemeanor to omit, willfully or negligently, any act required by Chapter 2 through Chapter 6 of Part 2 of Division 4, a range running from section 4251 to section 4411 and taking in PRC 4292 and 4293 along the way. What the section does not do is set a punishment. Penal Code section 19 supplies the default.
Absent a different punishment prescribed by law, a misdemeanor carries up to six months in county jail, a fine of up to $1,000, or both. Charging it is not the Department's decision. Under Government Code section 26500 the district attorney is the public prosecutor and, within his or her discretion, initiates and conducts prosecutions for public offenses on behalf of the people.
Hold that number next to the CPUC's for a moment, because the asymmetry explains a great deal of how these files are treated. A statutory clearance shortfall on brush-covered land, prosecuted to conviction, tops out at $1,000 and six months. The same span's nonconformance under a General Order runs against a penalty ceiling of $100,000 per offense with each day of a continuing violation counted separately. The heavier exposure attaches to the rule with the smaller clearance number.
The second route is the nuisance. PRC 4171 provides that any condition endangering public safety by creating a fire hazard, existing upon property included within a State Responsibility Area, is a public nuisance, with abatement machinery behind it. That characterization is available on one side of a boundary and not the other, and where that boundary runs, and how it moves without a hearing, is a separate question with a dated answer.
The third is money, and it arrives after a fire rather than before one. Health and Safety Code section 13009 reaches any person who negligently, or in violation of the law, sets a fire, allows a fire to be set, or allows a fire kindled or attended by that person to escape onto public or private property.
That person is liable for the costs of suppressing it, recoverable by the person or agency that incurred them. Participating public agencies may designate one or more of their number to bring the action on behalf of all. That is a civil action about causation, not a compliance finding about a distance, and it is the only CAL FIRE-adjacent route in this section whose magnitude resembles the CPUC's.
One duty runs the other direction, from utility to Department rather than the reverse, and it is the only regular filing CAL FIRE receives out of this stack: the annual Exempt Tree database and report due by July 1 under 14 CCR 1257(a)(3)(B). Beyond that, Title 14 Article 4 imposes no record obligation on the clearance work itself, which means the Department's own regulations do not create the file its inspectors would need in order to check the work from a desk.
NERC registers a function, not a utility
The federal route is the one that ignores everything the other three care about. FAC-003 does not attach to a company because it is a utility, or to a span because of what grows under it. It attaches because an entity appears on the NERC Compliance Registry for a function.
The Turlock filing spells that out with unusual clarity. Footnote 3 records that WECC confirmed the district was included on the NERC Compliance Registry on June 17, 2007, under registry ID NCR05435. The registration covered eleven functions:
Balancing Authority
Distribution Provider
Generator Operator
Generator Owner
Load Serving Entity
Planning Authority
Purchasing-Selling Entity
Resource Planner
Transmission Operator
Transmission Owner
Transmission Service Provider
Then the sentence that decides the vegetation question: "TID, as a TO, is subject to the requirements of FAC-003-1." One line, one function, one standard. Which lines that registration then reaches, and which it leaves alone, is a separate test applied inside the standard.
The facts of the violation are worth reading because they are the ordinary facts of a distribution program, at 230 kV. At 1353 PDT on August 29, 2007, a fault on the Westley-Walnut 230 kV line caused by vegetation contact relayed the line, and automatic and manual load shedding at Turlock and Modesto Irrigation District dropped nearly 40,000 customers, many for an hour and thirteen minutes. The tree was an almond, estimated at 25 to 30 feet, between towers J22-2 and J22-3, inside the right of way.
The district's own Transmission Vegetation Management Program had established a maximum allowed tree height of 17 feet. WECC found that at the time of the previous inspection four months earlier the tree was already closer than the program's 12-foot Clearance 1 requirement, and likely less than four feet from the conductor under normal operating conditions. An inspector had walked that span on October 6, 2006 and again on April 10, 2007 and noted no tree clearance issues.
The enforcement path from there is unlike anything in the state system. WECC investigated. On April 1, 2009, WECC and the district executed a Settlement Agreement, and the district neither admitted nor denied the determinations. NERC filed the Notice of Penalty at FERC on November 13, 2009, with an $80,000 aggregate penalty covering eight violation tracking numbers across six standards.
The penalty's own effective date is set by the federal layer above it:
Pursuant to Order No. 693, the penalty will be effective upon expiration of the thirty (30) day period following the filing of this Notice of Penalty with FERC, or, if FERC decides to review the penalty, upon final determination by FERC.
Three features of that sequence have no analogue in California enforcement. The Regional Entity investigates and settles rather than citing. The result is filed with a federal commission that can take it up on its own motion. And the ceiling is federal: Federal Power Act section 316A, 16 U.S.C. 825o-1(b), provides that a person violating the relevant provisions "shall be subject to a civil penalty of not more than $1,000,000 for each day that such violation continues," a figure FERC adjusts annually for inflation.
What the current standard requires, and what its evidence retention looks like against the state's, is the working version of all this. And what the retirement of R2 did to how a finding on a line like Westley-Walnut is written today changed the sorting rather than the duty.
The utility is the only body that can direct a crew
The fourth enforcer is the one that appears in every other body's paperwork as the respondent, and it is also the only one with an instruction that reaches a person holding a saw.
Nothing in this stack names a contractor. GO 95 Rule 35 binds the company that owns or operates the facility. PRC 4292 and 4293 bind "any person that owns, controls, operates, or maintains" the line. FAC-003 binds a registered Transmission Owner or Generator Owner.
A vegetation contractor is none of those things with respect to the conductor, which means no regulator in this subject will issue anything to a crew, a foreman, a prime or a subcontractor. The work is enforced through the contract, through the specification, and through the utility's own program.
That last item is not a soft obligation, and the three enforcement documents in this page all turn on it. Energy Safety measured SCE against SCE's four feet. WECC measured Turlock against Turlock's 17-foot maximum tree height and its own 2007 annual work plan. And SED's audit of the district opened with the district's own Preventative Maintenance Program and found the program internally inconsistent before it found anything on a pole: the inspection cycles section did not align with the intervals in the distribution inspections section.
The rule that produces is simple and rarely stated. In every one of these regimes, a written internal standard that is more demanding than the regulation becomes the standard the finding is measured against.
A specification promising 12 feet at time of trim, in a plan or a program an agency can read, is not the guideline it is inside GO 95 once it is quoted back by an inspector standing at the pole. That is an argument for writing specifications the program can actually hold, and for keeping the aspirational language out of the documents that get filed.
The same 30 inches, filed four ways
Take one measurement and run it through all four routes. A 230 kV transmission span at 400 feet elevation, inside Tier 2 of the High Fire-Threat District, crossing brush-covered land in a State Responsibility Area during declared fire season, with a limb measured at 30 inches from the nearest conductor on a September afternoon.
Under FAC-003-5, if the line is applicable, 30 inches is inside the 4.0-foot Minimum Vegetation Clearance Distance for that voltage and altitude band. An encroachment observed in Real-time absent a Sustained Outage is a Requirement R1 failure at a High Violation Severity Level. The finding goes into the entity's own evidence, and it surfaces to WECC through a self-report or an audit, not through a field notice.
Under GO 95 Rule 35, the span owes Case 14's 120 inches and is 90 inches short. It becomes a nonconformance in the company's own auditable maintenance program, with a priority level and a correction period set by a qualified company representative at the moment of identification. Nobody outside the company sees it unless an audit asks or a fire follows.
Under PRC 4293, the span owes ten feet radially at that voltage and is 90 inches short of that too, on a statute whose omission is a misdemeanor. If a fire agency inspector saw it first, the number would be a visual estimate on an LE-38a and a copy would go to the utility.
Under an approved wildfire mitigation plan, whatever the utility promised for that circuit is the number, and an Energy Safety inspector selecting a location from the utility's own quarterly data report is checking the promise rather than the code.
Four findings, four due dates, four addressees, one limb. They do not merge, they do not cancel, and satisfying the smallest of them proves nothing about the other three. Which pages of the file each of those readers arrives through is the practical version of that sentence.
What the record has to name
An enforcement route is a fact about a finding, and like every other fact in this stack it is only useful if the file states it rather than implies it.
The body the finding came from, and the instrument. An audit report, a citation, a Notice of Violation, an LE-38a, a Notice of Penalty and an internal work order are six different documents with six different clocks. A file that records "CPUC finding" without saying whether it arrived as an audit item or a citation cannot tell a later reader whether a penalty was accruing.
The rule cited, in the citing body's own vocabulary. GO 95 Rule 35 with the Table 1 case, PRC 4293 with its subdivision, FAC-003-5 R1 with its part, or a WMP initiative number such as 8.2.3.3.1. An entry that translates the finding into the program's internal categories and keeps no copy of the original wording has lost the thing the response has to answer.
The response deadline as a date, and its source. Thirty days from service on a CPUC citation. Thirty days from issuance on an Energy Safety NOV, which is also the deadline for requesting a hearing. Whatever the audit letter states, which in Turlock's case was 28 days. Those are not the same as the correction deadline, and the two are frequently recorded in one field.
The correction deadline, and which table produced it. A Minor Energy Safety violation in Tier 2 runs twelve months or the next WMP update. A Level 2 GO 95 nonconformance creating a fire risk in Tier 2 runs on the General Order's ceiling and on whatever tighter period the company's own representative set. Both can attach to the same pole.
The internal document the finding was measured against. The specification, the plan initiative, the program section, with its revision. In three of the four enforcement examples on this page, that document is what the finding actually cited.
The name and address of the receiving agency where it is not obvious. The responsible fire protection agency is a county department in the six contract counties and a named city or district agency outside the State Responsibility Area. An access report or a refusal notice sent to the wrong Unit is not evidence of anything.
Set against the district this page opened with, that discipline is the whole difference between two files. One of them can show, fifteen years later, which body asked for what, on which date, and what was sent back. The other has an $80,000 settlement and an audit report in it and no way to demonstrate that the second learned anything from the first.

Frequently asked questions
Does CAL FIRE enforce GO 95 Rule 35?
No. The California Power Line Fire Prevention Field Guide states at page 63 that protection agency personnel should know GO 95 but have no responsibility for enforcing it, and that their role is to observe infractions and report them to the utility. CAL FIRE enforces the Public Resources Code. The CPUC enforces its own General Orders, and it does not enforce PRC 4292 or 4293.
Can the CPUC issue a citation to a municipal utility or an irrigation district?
The Commission audits them. Public Utilities Code sections 8002, 8037 and 8056 extend its jurisdiction to publicly owned utilities for the limited purpose of safety rules governing electric transmission and distribution facilities, and the Safety and Enforcement Division conducts GO 95, GO 128 and GO 165 audits of them. The electric safety citation program adopted in D.14-12-001 is directed at electrical corporations, so a publicly owned utility's audit normally closes with a written response that the Commission posts publicly rather than with a fine.
Who does a vegetation contractor answer to?
Its client. No regulator in this stack names a contractor. GO 95 Rule 35 binds the company that owns or operates the facility, PRC 4292 and 4293 bind the person who owns, controls, operates or maintains the line, and FAC-003 binds an entity on the NERC Compliance Registry as a Transmission Owner or Generator Owner. A crew's work is enforced through the contract and through the utility's own maintenance program, which is itself the document an auditor reads first.
What is the criminal exposure for a PRC 4293 shortfall?
PRC 4021 makes the willful or negligent omission of an act required by Chapter 2 through Chapter 6 of Part 2 of Division 4 a misdemeanor. It prescribes no punishment of its own, so Penal Code section 19 supplies the default: up to six months in county jail, a fine of up to $1,000, or both. The Department cannot impose that itself. A misdemeanor is charged by the county's public prosecutor under Government Code section 26500.
Who enforces a utility's wildfire mitigation plan commitments?
The Office of Energy Infrastructure Safety inspects work against the approved plan and issues a Notice of Violation under Public Utilities Code section 326 and Government Code section 15475.1. The electrical corporation has 30 days to respond or request a hearing, and under Public Utilities Code section 8389(g) the matter may then be referred to the CPUC for consideration of enforcement action.
