AB 2700 amends Section 738.6 of the California Public Utilities Code by changing the statutory wording that governs how the California Public Utilities Commission (CPUC) treats expenses tied to compliance with state and local air pollution control rules for using clean‑burning fuels in federally designated nonattainment areas. The statutory duty—having the CPUC determine which of those expenses are reasonable and necessary and approving them—remains in place.
The change is framed as nonsubstantive: it does not create new rate‑making obligations, funding mechanisms, or enforcement powers. Nevertheless, even small textual edits can affect how utilities, ratepayer advocates, and courts read a statute; compliance officers and counsel should update internal references and watch for any challenges that try to treat the edit as altering CPUC discretion or the scope of recoverable costs.
At a Glance
What It Does
The bill revises the text of Public Utilities Code §738.6 without adding new substantive requirements: the CPUC still must identify which expenses incurred to meet state and local air pollution control mandates for clean‑burning fuels in federally designated nonattainment areas are reasonable and necessary, and approve those costs. The amendment is presented as a technical/drafting correction rather than a policy change.
Who It Affects
CPUC‑jurisdiction utilities (primarily investor‑owned electric and gas utilities) operating any portion of their systems in federally designated nonattainment areas, CPUC staff who handle rate cases and advice letters, regional air quality districts that impose compliance obligations, and ratepayer advocates who litigate cost recovery disputes.
Why It Matters
By tightening statutory wording, the bill aims to reduce textual ambiguity that can fuel procedural fights in rate proceedings and appeals. Because the statute still leaves substantive boundaries—what counts as a reasonable, necessary expense and what 'clean‑burning fuels' means—to administrative processes, the practical allocation of costs will continue to be decided at the CPUC level.

What This Bill Actually Does
Section 738.6 has long directed the CPUC to decide which costs utilities incur to comply with state and local mandates on clean‑burning fuels in federally designated nonattainment areas are reasonable and necessary, and to approve those costs for recovery in rates. AB 2700 does not change that substantive framework.
Instead, it replaces one phrase in the statute as a drafting correction; the Legislature describes the edit as nonsubstantive.
The bill text as filed tweaks the phrasing in the operative sentence that names the CPUC's duty. On its face this is an editorial move to remove or correct a drafting irregularity rather than to broaden or narrow the CPUC’s authority.
Because the CPUC’s core responsibilities—evaluating prudence, allocating costs across ratepayers, and deciding the appropriate recovery vehicle (general rate case, balancing account, or advice letter)—are set by other statutes and longstanding practice, AB 2700 is unlikely to change day‑to‑day ratemaking mechanics.Practically, the workstream for utilities and compliance teams stays the same: when an air district or state regulation forces a switch to cleaner fuels, utilities continue to document expenses, file for recovery with the CPUC, and defend the reasonableness and necessity of those costs in hearings. Ratepayer advocates will still press for limits and offsets; air districts will still set standards that generate the costs.
The primary change for most stakeholders will be administrative—updating citations, ensuring CPUC orders reference the revised text, and monitoring whether any party treats the wording change as an opening to relitigate prior rulings.Finally, because AB 2700 contains no definitions of terms such as "clean‑burning fuels" and does not alter existing procedural pathways, the CPUC will remain the body that interprets eligibility and recovery mechanisms. That means the precise line between capital and operating costs, and between routine upgrades and extraordinary compliance spending, continues to be shaped in CPUC proceedings rather than by this statutory edit.
The Five Things You Need to Know
AB 2700 amends Public Utilities Code §738.6 by altering the statutory phrasing that directs CPUC treatment of costs tied to compliance with clean‑fuel air regulations.
The statute continues to require the CPUC to determine which compliance expenses are "reasonable and necessary" and to approve those expenses for recovery in rates.
The legislative files characterize the change as nonsubstantive; the bill does not create new obligations, penalties, or funding streams.
The bill contains no appropriation and did not require referral to the fiscal committee, indicating the Legislature expects no direct state cost impact.
The text as printed does not include an express effective date; under California practice, an ordinary statute without an urgency clause generally becomes effective on January 1 following enactment.

Technical wording change to the CPUC's existing duty
This provision replaces the operative sentence of §738.6 with revised wording that the Legislature describes as nonsubstantive. The CPUC's mandate—to identify and approve reasonable and necessary expenses incurred to comply with state and local air pollution control requirements for using clean‑burning fuels in federally designated nonattainment areas—remains intact. For practitioners, this is an editorial change to the statute's text rather than a new policy.
How §738.6 fits into California ratemaking
Section 738.6 operates alongside other ratemaking statutes and CPUC practices that govern prudence reviews, balancing accounts, and general rate cases. It functions as a directional rule: when compliance costs arise from air quality mandates, the CPUC must evaluate them for recoverability. The amended wording does not substitute a new recovery mechanism; it simply keeps the decision about eligibility and reasonableness within the CPUC's established rate‑setting processes.
No new fiscal or enforcement apparatus
The bill's digest and bill text indicate no appropriation and no fiscal committee referral. There is no new enforcement mechanism or penalty provision attached to the amendment. That confirms the amendment is drafting‑oriented and not intended to expand state budgetary obligations or create a separate compliance or enforcement program.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- CPUC staff and commissioners — clearer statutory wording reduces the chance that a drafting error will generate procedural challenges or require clarifying legislative fixes.
- Investor‑owned utilities operating in nonattainment areas — the edit preserves their existing pathway to seek rate recovery for expenses tied to meeting state and local clean‑fuel mandates.
- Regional air quality districts — stable recovery mechanisms make it more predictable that regulated entities can fund compliance measures ordered by districts, supporting enforcement of local air quality rules.
- Ratepayers generally — to the extent the amendment prevents procedural disputes, ratepayers avoid the litigation costs and delays that can affect how and when costs are recovered.
Who Bears the Cost
- Utility legal and regulatory teams — they must update internal templates and filings to reflect the amended citation and monitor whether opponents seize on the wording change to revisit prior decisions.
- Ratepayer advocacy groups — minimal direct cost, but they may need to review whether the textual edit affects ongoing or future litigation strategy in cost recovery cases.
- CPUC administrative staff — minor operational work to update orders, rule texts, and guidance documents to match the revised statutory language.
- Courts and litigants (potentially) — if a party treats the edit as substantive, additional litigation could impose costs on all parties, even though the Legislature labeled the change nonsubstantive.
Key Issues
The Core Tension
The bill exemplifies the trade‑off between drafting clarity and legal finality: fixing a statutory draft error aims to prevent ambiguity, but even a small wording change can invite new challenges that reopen settled questions about the CPUC's authority and the contours of recoverable compliance costs.
Two implementation tensions are worth highlighting. First, even an ostensibly nonsubstantive edit can alter litigation incentives.
If a party argues that the revised wording narrows or broadens the CPUC’s discretion—especially around the phrase "shall approve those expenses"—courts may be asked to interpret legislative intent and the amendment's scope. That litigation risk is the opposite of the bill's apparent purpose and could generate the procedural fights the edit sought to avoid.
Second, the statute remains silent on several consequential matters that determine real‑world cost allocation: it does not define "clean‑burning fuels," it does not specify which categories of expense (capital, O&M, administrative) are presumptively recoverable, and it does not prescribe the recovery mechanism (general rate case, balancing account, or advice letter). Those substantive questions stay delegated to CPUC processes, where rate design, amortization periods, and cross‑subsidization between customer classes are decided.
The amendment reduces textual noise but leaves the hard policy choices in administrative proceedings—where they will still generate trade‑offs between environmental objectives and ratepayer protections.
