The Idaho Board of Scaling Practices is considering adoption of a new cubic log scaling manual to give another option for log scaling methodology. The new cubic manual would be an alternative to the current Idaho Log Scaling Manual and is not meant to be a replacement.

Current rules of the Idaho Board of Scaling Practices allow for cubic log scaling; however, the Scaling Board does not have a cubic scaling manual that establishes the rules and procedures for cubic log scaling. The U.S. Forest Service cubic scaling manual is not compliant with several of the gross scale determination rules established by the Scaling Board.

This rulemaking is needed to maintain a consistent cubic scale volume anywhere within the state, should parties to a timber sale contract or log purchase agreement elect to scale in cubic volume.

Currently, the Idaho Log Scaling Manual includes only the Scribner Decimal “C” methodology. By adopting the Idaho Cubic Log Scaling Manual, this rulemaking would ensure that both Scribner and cubic scaling methods are compliant with the current rules as established by the Idaho Board of Scaling Practices.

This rule chapter will also be repealed and replaced per Executive Order 2020-01: Zero-Based Regulation.
