Board denies most time-extension requests for cannabis odor controls after contentious hearing

The Santa Barbara County Board of Supervisors on March 10 declined to grant most of eight coastal operators additional time to meet new odor-control requirements enacted last year, voting 4-1 to deny the staff-submitted extension requests after extensive testimony from operators, vendors and neighborhood residents.

Lede: Planning staff had reviewed each operator's revised odor-abatement plan (OAP) and delivery/installation schedules and, where operators had delayed starting engineering or procurement, recommended denial. After applicant presentations, vendor demonstrations and extensive public comment, the board approved staff's recommended denials by roll call (4–1), with supervisors citing long lead times in planning and late start of compliance work by several operators.

Why it matters: The county's updated cannabis ordinance requires indoor cultivation and processing facilities (coastal zone) to submit revised odor-abatement plans, install multi-technology carbon filtration or an equivalent, and meet a property-line odor threshold. The board's decision enforces the March compliance timeline and signals stricter enforcement for operators who did not begin compliance work early enough to meet the deadline.

What happened at the hearing: Planning staff categorized applicants by OAP and equipment status; some operators had purchased equipment and submitted OAPs under review, others were awaiting Southern California Edison power upgrades, and one applicant was recommended for denial for delayed engagement. Neighbors testified that odor remains a persistent quality-of-life problem and urged denial of extensions; vendors and operators described supply-chain, permitting and electrical constraints and urged short limited extensions. The board heard technical testimony from the Air Pollution Control District (APCD) about potential byproducts from certain photochemical oxidation (PCO) technologies and from vendors who said modern PCO units, often CARB-tested, can operate within safety thresholds.

Board action and consequences: The board adopted staff findings to deny the set of extension requests (motion passed 4-1). Operators denied extensions may be issued notices of violation, and the county's CEO office (chapter 50 compliance) can pursue license suspension or revocation following administrative-appeals procedures; planning staff will continue OAP reviews and compliance inspections. Operators whose OAPs are complete and equipment installed but not approved were directed to work with staff; the board left in place a path for appeals under county administrative hearings.

Voices: "Neighbors deserve relief from persistent odor," said a local resident during public comment. Planning staff noted many OAPs were submitted late in the year-long compliance window and that county reviewers had raised robust technical comments. APCD cautioned about unproven PCO-only systems and recommended carbon filtration or proof of safe operation; vendors countered that properly engineered PCO systems have laboratory and field tests showing efficacy and safe byproduct levels.

What's next: Planning will continue quarterly compliance inspections and odor monitoring, and enforcement staff will follow up on remaining noncompliant facilities. Operators may pursue administrative appeals of any license-suspension decisions; the county noted that operations may continue through the appeal process until a final administrative action is taken.

Provenance: Planning's time-extension review and the full public hearing are documented in the transcript beginning with the staff presentation at SEG 7159 and continuing through the board's roll-call ruling at SEG 10400.
