California Code, Health and Safety Code - HSC § 41804

(a) The district board finds that it is more desirable to dispose of such waste by burning than to dispose of it by other available means, such as, but not limited to, by removing it to sanitary fills.

(b) The district has developed criteria for such disposal, which shall include provisions to improve the combustibility of such waste to reduce its smoke level.

(c) The state board has approved the criteria developed pursuant to subdivision (b).

(d) Such authorization, if granted, shall be in the form of a permit issued by the district air pollution control officer, and such permit shall allow burning only on days during which agricultural burning is not prohibited by the state board pursuant to Section 41855.

(e) The district board may adopt rules and regulations to authorize any burning authorized under Section 41802, to review each proposed burn prior to authorizing its air pollution control officer to issue a permit for the burn, or to delegate to its air pollution control officer the authority to approve or disapprove each proposed burn after consideration of the amount of waste to be burned, the season of the year, the ambient air quality, the proximity of the waste to developed areas, or such other or additional criteria as the district board may establish.
