Health and Safety Code § 39516

Any power, duty, purpose, function, or jurisdiction which the state board may lawfully delegate shall be conclusively presumed to have been delegated to the executive officer unless it is shown that the state board, by affirmative vote recorded in the minutes of the state board, specifically has reserved the same for the state board’s own action.

The executive officer may redelegate to his subordinates unless, by state board rule or express provision of law, the executive officer is specifically required to act personally.
