Section 1535.30  Volume Estimates

a)         When volume estimates are used in the determination of value, the following scales and measurements will be used:

1)         Lumber, cooperage, & veneer – Board feet taken from the Doyle Log Rule as published in the Forestry Handbook Second Edition (1984) edited for the Society of American Foresters by Karl F. Wenger and published by John Wiley and Sons.

2)         Pulpwood, ton or cord – As established by local market specifications in use at the time of cutting or delivery to the pulpwood mill.

3)         Piling – Linear feet by grade within established specifications and dimensions in use by the buyer.  If such specifications cannot be determined, the Doyle Log Rule will be used.

4)         Other specialized forest products – Established  local market specification or custom in use at the time of harvest as described by the buyer in a written communication to the Department.

b)         Standard forest mensuration procedures shall be used whenever estimates are substituted for actual measurements provided that the procedure has a probability of error of less than ten percent.

c)         In the establishment of volume-price values, such published price guides as the Illinois Timber Prices Survey may be used as a guide when published by a government agency, accredited school of forestry or trade association.
