Terms used in this Rule shall have the meaning specified below. The meaning of any term not defined below may be taken from definitions in other rules of the Department, unless such meaning would defeat the purposes or intent of this rule.

(1) “Animal feeding operation” means a lot or facility (other than an aquatic animal production facility) where the following conditions are met:

(a) Animals have been, are or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12 month period; and

(b) Crops, vegetation, forage growth or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility.

(c) Two or more animal feeding operations under common ownership are deemed to be a single animal feeding operation if they are adjacent to each other or if they utilize a common area or system for the disposal of wastes.

(2) “Animal unit” means a unit of measurement for an animal feeding operation calculated by adding the following numbers: the number of slaughter and feeder cattle multiplied by 1.0, plus the number of mature dairy cattle multiplied by 1.4, plus the number of swine weighing over 55 pounds multiplied by 0.4, plus the number of sheep multiplied by 0.1, plus the number of horses multiplied by 2.0.

(3) “Concentrated animal feeding operation” means a feeding operation where more animals are confined than are specified in the categories listed below. Any animal feeding operation that contains process wastewater and runoff from the 25-year, 24-hour storm event, is not considered a concentrated animal feeding operation regardless of the number of animals at the facility.

(a) 1,000 slaughter and feeder cattle,

(b) 700 mature dairy cattle (whether milked or dry cows), except that dairy farms located in the Lake Okeechobee Drainage Basin as defined in subsection 62-670.200(8), F.A.C., shall be regulated pursuant to Rule 62-670.500, F.A.C.,

(c) 2,500 swine weighing over 55 pounds each,

(d) 500 horses,

(e) 10,000 sheep or lambs,

(f) 55,000 turkeys,

(g) 100,000 laying hens or broilers (if the facility has continuous overflow watering),

(h) 30,000 laying hens or broilers (if the facility has a liquid manure handling system),

(i) 5,000 ducks, or

(j) 1,000 animals units.

(4) “Dairy Farm” means any operation as defined in subsection 5D-1.001(49), F.A.C., and regulated by the Florida Department of Agriculture and Consumer Services.

(5) “Egg production facility” means a commercial facility housing laying hens or cleaning, sorting and preserving eggs.

(6) “Egg wash wastewater” means wastewater generated as a result of cleaning, sorting and preserving eggs.

(7) “High intensity use area” means all areas of concentrated animal density generally associated with milking barns, feedlots, holding pens, travel lanes and contiguous milk herd pasture where the permanent vegetative cover is equal to or less than 80 percent, under average annual worst-case conditions, as determined by USDA Soil Conservation Service methods.

(8) “Lake Okeechobee Drainage Basin” means the drainage basin consisting of the following sub-drainage basins:

(a) Lower Kissimmee River basin below structure S-65;

(b) Taylor Creek – Nubbin Slough basin;

(c) Fish Eating Creek basin;

(d) Indian Prairie and Harney Pond basins;

(e) C-41A basin;

(f) Nicodemus Slough basin; and

(g) Drainage areas tributary to the South Florida Water Management District Pump Stations designated as S-127, S-129, S-131, S-133, S-135, S-2, S-3, and S-4. The geographical boundaries of these sub-basins shall be as designated by the South Florida Water Management District in its Technical Publication 81-2, May, 1981.

(9) “Liquid manure system” means a system for conveyance of manure which uses water.

(10) “Major egg production facility” means an egg production facility which has:

(a) More than 100,000 laying hens, or

(b) More than 30,000 laying hens when the facility has a liquid manure system, or

(c) On site facilities which process at least the number of eggs produced by 100,000 laying hens, not necessarily from on site hens, on a daily basis.

(11) “Man-made” means constructed by man and used for the purpose of transporting wastes.

(12) “Management Plan” means a site-specific detailed plan, with design calculations, providing for collection, storage and disposal of all wastewater from the milking barn, and of the runoff from the 25-year, 24-hour storm event from all “high intensity” areas within the dairy farm. In addition, the plan shall include provision for implementation of required management practices. Such plan shall be prepared in accordance with the standards of the USDA Soil Conservation Service and shall include detailed instructions for operation and maintenance of wastewater/runoff collection, storage and disposal systems.

(13) “Process generated wastewater” means water directly or indirectly used in the operation of a feedlot for any or all of the following: Spillage or overflow from animal or poultry watering systems; washing, cleaning or flushing pens, barns, manure pits or other feedlot activities; direct contact swimming, washing or spray cooling of animals; and dust control.

(14) “Process wastewater” means any process generated wastewater and any precipitation which comes into contact with any manure, litter of bedding, or any other raw material or intermediate product used in or resulting from the production of animals or poultry or direct products.

(15) “25-year, 24-hour Storm Event” means the amount of rainfall within 24 hours that is likely to be exceeded on the average only once in 25 years, as published by the U.S. Weather Bureau in Technical Paper 40 “Rainfall Maps for 24-hour Rainfall Amounts for the Coterminous United States.”
