Specific Authority 570.07(23),(28) FS. Law Implemented 570.07(28), 570.548, 590.02(1)(b), 590.125(2), (3) FS. History–New 7-1-71, Formerly 17-5, 7-1-75, 5I-2.04, Amended 9-8-93, 8-16-95, 10-18-99.

5I-2.006 Open Burning Allowed.

(1) Open Burning in General. Authorization must be obtained from the Florida Division of Forestry for burns relating to agriculture, silviculture and rural land clearing on the same day the burn is to take place or after 4:00 p.m. of the previous day. The Division of Forestry may set special requirements for authorizations in order to protect public safety, including but not limited to on site inspections. Any authorized burn that goes out of compliance will be allowed a maximum of two hours to be brought into compliance by the person responsible. In the event that the Division determines that there is a threat to life, public safety or property, immediate suppression action will be taken.

(a) Non-Certified Daytime Authorizations will be issued for the burning to be conducted from 9:00 a.m. and the fire must discontinue spreading one hour before sunset except for Certified Prescribed Burn Mangers.

(b) Non-Certified Nighttime Authorizations will be issued with a Dispersion Index of 8 (except for Certified Prescribed Burn Managers) for the burning to be conducted between one hour before sunset and 9:00 a.m. Ignition of these fires is authorized up to midnight, however the fire can continue to spread until 9:00 a.m. the following day. If additional time is required a new authorization (daytime) must be obtained from the Division.

(2) Open Burning for Certified Prescribed Burn Managers. (All burning conducted under this section must relate to Silviculture, Wildlife Management, Ecological Maintenance and Restoration, and Range Management. Burning in accordance with this section entitles the burner to the protection offered in Section 590.125(3)(c), Florida Statutes.) Open burning authorizations under this section require the Certified Prescribed Burn Manager’s certification number be presented at the time of the request, and that a Certified Prescribed Burn Manager be on site for the entire burn.

(a) Prescription. A prescription for the burn must be on site and available for inspection by a Department representative. The prescription will contain, as a minimum, the following:

1. Stand or Site Description;

2. Map of the area to be burned;

3. Personnel and equipment to be used on the prescribed burn;

4. Desired weather factors, including but not limited to surface wind speed and direction, transport wind speed and direction, minimum mixing height, minimum relative humidity, maximum temperature, and fine fuel moisture;

5. Desired fire Behavior Factors, such as type of burn technique, flame length, and rate of spread;

6. The time and date the prescription was prepared;

7. The authorization date and the time period of the authorization;

8. An evaluation and approval of the anticipated impact of the proposed burn on related smoke sensitive areas;

9. The signature and number of the Certified Prescribed Burn Manager.

(b) Open Burning Hours

1. Daytime Authorizations will be issued for the burning to be conducted from 9:00 a.m. and the fire must discontinue spreading one hour after sunset.

2. Nighttime Authorizations will be issued with a Dispersion Index of 6 or above for the burning to be conducted between one hour before sunset and 9:00 a.m. the following day. Ignition of these fires is authorized up to midnight, however the fire can continue to spread until 9:00 a.m. the following day. If additional time is required a new authorization (daytime) must be obtained from the Division. The Division may issue authorizations at other times, in designated areas, when the Division has determined that atmospheric conditions in the vicinity of the burn will allow good diffusion and dispersement of air pollutants, and the resulting smoke from the burn will not adversely impact critical smoke sensitive areas, e.g., highways, hospitals and airports.

(c) Burn Manager Certification Process. Certification to become a Certified Prescribed Burn Manager is accomplished by:

1. Satisfactory completion of the Division of Forestry’s Prescribed Fire Correspondence Course and direct experience in three prescribed burns prior to taking the course or;

2. Satisfactory completion of the Florida Inter-Agency Basic Prescribed Fire Course and direct experience in three prescribed burns.

3. In order to continue to hold the Division of Forestry Prescribed Burn Manager Certification the burner must comply with paragraph 5I-2.006(2)(d), F.A.C., or Division Certification will terminate five years from the date of issue.

(d) Certification Renewal.

1. Participation in a minimum of eight hours of training every five years relating to the subject of prescribed fire, or participation in a North/Central Prescribed Fire Council or South Florida Fire Council Meeting, and

2. The Certified Prescribed Burn Manager has submitted their certification number for two completed prescribed burns in the preceding five (5) years, or

3. Participation in five (5) burns and have this documented and verified by a current Certified Prescribed Burn Manager, or

4. Retaking either the Prescribed Fire Correspondence Course or the Inter-Agency Basic Prescribed Fire Course.

(e) Decertification. The Commissioner of Agriculture will revoke any Certified Prescribed Burn Manager’s certification if they demonstrate that their practices and procedures repeatedly violated Florida law or agency rules or is a threat to public health, safety, or property.

(3) Pile/Windrow Burning.

(a) General. Piles or windrows shall not have visible flame one hour before sunset or anytime thereafter, except in smoke sensitive areas where the piles must be completely extinguished one hour before sunset. The size and number of piles shall be dictated by the materials to be burned and the time available for burning.

1. The moisture content and composition of the materials to be burned shall be favorable to good burning which will minimize air pollution. The amount of dirt in the piles or rows shall be minimized to enhance combustion and reduce emissions.

2. The pile burning must be set back one hundred (100) feet from any paved public highway and the prevailing winds will direct the smoke away from any occupied buildings or roads.

(b) Agriculture and Silvicultural Pile/windrow burning must be set back three hundred (300) feet from any occupied building except the landowner’s buildings.

(c) Rural Land Clearing. Open burning of wooden material or vegetation generated by a land clearing operation is allowed provided that all of the following conditions are met:

1. The open burning meets one of the following setback requirements:

a. Residential Land Clearing must be set back three hundred (300) feet or more away from any occupied building for residential land clearing, and clearing for residential enhancement of property value and aesthetics, or

b. Non-Residential with Air Curtain must be setback three hundred (300) feet or more from any occupied building if an air curtain incinerator is used, or

c. Non-Residential without Air Curtain must be setback one thousand (1000) feet or more away from any occupied building if air curtain incinerator is not used and the operation is not residential land clearing, or

d. Exception to Setbacks – An exception to the setbacks in sub-subparagraph 5I-2.006(3)(c)1.a.,b., and c., F.A.C., will be granted if the affected parties agree in writing to allow the burn to take place.

2. The use of Air Curtain Incinerators is allowed for the combustion of land clearing debris. No Department of Environmental Protection permits are required for air curtain incinerators that are designed and used as portable units and that will operate on any one site for less than six months in any year. Prior authorization to use a portable Air Curtain Incinerator must be obtained from the Division of Forestry. Operation of portable Air Curtain Incinerators shall be authorized provided that the following conditions are met:

a. Pit width, length, and side walls shall be properly maintained so that the combustion of the waste within the pit will be maintained at an adequate temperature and with sufficient air re-circulation to provide enough residence time and mixing for complete combustion and control of emissions. Pit width shall not exceed twelve (12) feet, and vertical side walls shall be maintained.

b. No waste will be burned above the level of the air curtain in the pit.

c. Excessive visible emissions are not allowed except for a period of up to 30 minutes during start ups and shutdowns.

3. Air Curtain Incinerators that are intended to be stationary units, i.e., continuously operate at one site for more than six months, or operate at any Department of Environmental Protection (DEP) permitted land-fill, must comply with the requirements of subsection 62-296.401(6), F.A.C., in effect on July 7, 1995, Florida Administrative Code.

4. Exceptions to the setback requirements from occupied buildings shall be granted by the Division of Forestry when the applicant obtains a signed written statement from every affected resident within the setback area that waives their objections to the open burning associated with the land clearing operation and presents the statement to the Division of Forestry 48 hours in advance of the burning.

(d) Any open burning that is allowed by this chapter is restricted to the site where the material was generated and such material shall not be transported to another property to be open burned, unless the rural land clearing debris has been generated by the person, or their agent, who owns the property where it was generated and to where it is transported, or operates an Air Curtain Incinerator provided that the following conditions are met:

1. It will be transported to property that is owned or leased by the person who generated the land clearing debris, and will not exceed 6 months from the date of the initial authorization and

2. Meets a setback distance of three hundred (300) feet from occupied buildings for Air Curtain Incinerators with vertical refractory-lined walls and with forced under draft air, or

3. Meets a setback distance of one thousand (1000) feet from occupied buildings for all other Air Curtain Incinerators or

4. Meets a setback distance of one thousand (1000) feet from occupied buildings for land clearing debris burned without an Air Curtain Incinerator.

(4) Open Burning Exceptions. The Director of the Division of Forestry is authorized to grant exceptions to the open burning rules within Chapter 5I-2, F.A.C., in the event of an emergency that would require the destruction of vegetative debris in the most expeditious means possible. Examples would include the burning of vegetative matter resulting from an insect or disease infestation, or the debris resulting from storm damage e.g., hurricanes or tornados.
