Rule 305  Minimum Drying Time

     305.1.    Prohibition.  No person required to comply with
               this Rule shall knowingly permit open outdoor
               fires that do not meet the following requirements.

     305.2.    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.   Sufficient time for agricultural waste such
                    as orchard prunings, small branches,
                    vegetable tops, and seed screenings to assure
                    rapid and complete combustion with a minimum
                    of smoke.

               C.   A minimum of six weeks for trees, stumps, and
                    large branches greater than six inches in
                    diameter.

               D.   For prescribed burning, the drying time shall
                    be specified by the designated agency.

               E.   For range improvement burning, the brush
                    shall 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.

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