(1) No new installations or replacements of vehicle or livestock scales may be placed in a pit where the clearance from the floor of the pit to the bottom of the I-beams is less than 42 inches.

(2) Scale pits are not required for fully electronic scales, unless the pit is necessary for the installation, operation, or maintenance of the particular scale.

(3) Electronic scales which do not require a pit for their installation, operation, or maintenance must be installed in strict compliance with the manufacturer's specification for each specific model and with the requirements of NIST Handbook 44, 2012 edition.

(4) Scale pits must have concrete walls surrounding the entire pit, substantial in both durability and strength to prevent soil, snow, and other materials from entering the pit area and preventing the scale from operating properly. The requirements of this rule will apply only to those scales installed after its adoption.
