LAST REVISED 08/28/91


Rule 305  Minimum Drying Times:

          305.1  Requirements.  To lower the moisture content of
          the material being burned, the elapsed time between
          cutting and burning shall be:

               A.   A minimum of three days for green straw and
                    stubble.

               B.   Vegetation such as orchard prunings, small
                    branches, vegetable tops, and seed screenings,
                    shall be in a dry condition to facilitate
                    combustion and minimize the amount of smoke
                    emitted.

               C.   A minimum of six weeks for trees, stumps, and
                    large branches greater than six inches in
                    diameter or as otherwise determined by the Air
                    Pollution Control Officer. 

               D.   Under Forest Management Burning the drying
                    time shall be specified by the designated
                    agency.

               E.   Under Range Improvement Burning the brush may
                    be felled, crushed or uprooted with mechanical
                    equipment, or desiccated with herbicides, or
                    dead at least six months prior to the burn if
                    economically and technically feasible.

               F.   Under Wildland Vegetation Management Burning,
                    drying time will be stated in the Burn Plan
                    Rule 307.2.

          305.2 Exemptions.

               A.   Diseased or pest prevention burning is
                    exempted from drying times.

               B.   The APCO may, by permit, authorize shorter
                    drying times if the denial of such a permit
                    would threaten imminent and substantial
                    economic loss.
