26 Cal. App. 5th 93
Cal. Ct. App. 5th2018Background
- AC Transit operated hundreds of buses; only ~20% were air-conditioned. Division cited AC Transit for violations of Cal. Code Regs., tit. 8, § 3395 (heat-illness prevention) based on non-air-conditioned bus interiors: inadequate water, shade, and training.
- AC Transit conceded noncompliance but argued § 3395 did not apply because bus interiors are not "outdoor places of employment;" also raised vagueness defense (not pursued below).
- An ALJ dismissed the citations, finding "outdoor" ambiguous and not reasonably read to include bus interiors; the Appeals Board affirmed, adopting a plain-meaning "out of doors / open air" view.
- The Division petitioned for writ of mandate; Alameda County Superior Court reversed, holding "outdoor" may include non-air-conditioned enclosures that do not provide sufficient environmental protections to be "indoor," and directed the Appeals Board to reconsider under that definition.
- Court of Appeal conducted de novo review of the regulatory interpretation, examined § 3395 text and the Standards Board rulemaking record (ISOR/FSOR), and remanded for the Appeals Board to decide whether AC Transit buses "significantly reduce the net effect of the environmental risk factors that exist immediately outside."
Issues
| Issue | Plaintiff's Argument (AC Transit) | Defendant's Argument (Division) | Held |
|---|---|---|---|
| Whether interiors of non-air-conditioned buses are "outdoor places of employment" under § 3395 | Bus interiors are not "outdoors"; ordinary meaning excludes enclosed vehicle interiors | § 3395 and its rulemaking history show non-air-conditioned vehicles can be "outdoor" worksites subject to the standard | Court held "outdoor" can include non-air-conditioned vehicles that do not provide sufficient environmental protections to be considered indoor; remanded to determine if AC Transit buses meet that test |
| Whether the regulation's plain language controls or rulemaking history | Plain language excludes buses; Appeals Board relied on ordinary dictionary meanings | Regulatory history shows Standards Board intended coverage of non-air-conditioned vehicles and to treat enclosures that fail to reduce outdoor risk factors as "outdoor" | Court found plain language ambiguous and relied on the regulatory history to adopt the broader construction consistent with agency purpose |
| Whether continuous/intermittent outdoor exposure matters for coverage | (AC Transit argued intermittent nature makes coverage inappropriate) | Division: § 3395 covers workplaces that are outdoor even if exposure is intermittent; employer must account for recovery periods | Court said § 3395 covers intermittent outdoor work; employer responsibilities remain; Appeals Board should not relitigate compliance but assess whether buses are "outdoor" |
