No person required to comply with this Rule shall knowingly permit open outdoor fires on days when such burning is prohibited by ARB, the APCO, or the fire agency with appropriate jurisdiction.(Section 41854)

303.2. Permissive Burn or No-Burn Days.

  1. A notice as to whether the following day is a permissive-burn day, or no-burn day, or whether the decision will be announced the following day, shall be provided by the ARB by 3:00 p.m. daily for each of the air basins. If the decision is made by the following day it shall be announced by 7:45 a.m. Such notices shall be based on the Meteorological Criteria for Regulating Agricultural Burning, Article 3, Sections 80180 through 80320 of these Agricultural Burning Guidelines.
  2. Agricultural burning is prohibited on no-burn days, except as specified in Section 80102, subdivisions (d) and (e), and as may be permitted by a provision in an implementation plan adopted pursuant to Section 80150(c)(5).
  3. Upon request from a permittee through a designated agency, seven days in advance of a specific range improvement burn, forest management burn, or wildland vegetation management burn, at any elevation below 6,000 ft. (msl), a permissive-burn or no-burn notice will be issued by the ARB up to 48 hours prior to the date scheduled for the burn. Without further request, a daily notice will continue to be issued until a permissive-burn notice is issued.
  4. Notwithstanding subdivision (c) of Section 80110, the ARB may cancel permissive-burn notices that have been issued more than 24 hours in advance if the cancellation is necessary to maintain suitable air quality.
  5. A permissive-burn or no-burn advisory outlook will be available up to 72 hours in advance of burns specified in subdivision (c) of Section 80110.

303.3 Exception. The APCO may issue a special permit to authorize the use of open outdoor fires on No-Burn Days, when denial of such a permit would threaten imminent and substantial economic loss. In authorizing such burning a District shall limit the amount of acreage which can be burned in any one day and only authorize burning downwind of metropolitan areas forecasted by the Air Resources Board to achieve the ambient standards.
