(5) Any document submitted for recording that utilizes an Oregon Coordinate System shall use only one specified zone and system for the entire document.
(6) The use of the term “Oregon Coordinate System” on any document submitted for filing as a public record is limited to coordinates based on the Oregon coordinate systems as defined in ORS 93.330 and must include appropriate system date and zone designations. [Amended by 1985 c.202 §1]
