REGULATION VI - AGRICULTURAL BURNING

RULE 6.4 - PREPARATION OF AGRICULTURAL WASTE

Agricultural waste shall be dry enough to assure complete combustion, and shall be free from extraneous materials. The following are minimum standards for the preparation of agricultural waste prior to burning.

a. Shall be free of material that is not produced in an agricultural operation.

b. Shall be arranged so that it will burn with a minimum of smoke, and except for large trees, only that amount that can reasonably be expected to completely burn within the following 24 hours shall be ignited on any one day.

c. Shall be reasonably free of dirt, soil and visible surface moisture.

d. To lower the moisture content of agricultural waste, the elapsed time between cutting and burning shall be:

1. Rice and straw stubble, see Rule 6.7, subsection b.
2. A minimum of thirty (30) days for trees, stumps and large branches greater than six (6) inches in diameter.
3. Sufficient time for other agricultural waste such as orchard prunings, small branches, stubble, vegetable tops and seed screenings to assure rapid and complete combustion with a minimum of smoke.
4. District may authorize burning of agricultural waste in shorter times if the denial of such permit would threaten eminent and substantial economic loss.
