Senate Bill 877 was enacted in Oregon in 2011 to allow the use of the Oregon Coordinate Reference System or legacy State Plane Coordinates whenever the use of State Plane Coordinates was previously allowed. Nothing in Senate Bill 877 requires the use of the Oregon Coordinate Reference System.
The Oregon Transportation Commission adopted new Oregon Administrative Rules (OARs) defining the Oregon Coordinate System (734-005-0005, 734-005-0010, 734-005-0015) on December 21, 2011. The rules were filed with the Secretary of State on December 22, 2011 and became effective on January 1, 2012.
These rules implement Senate Bill 877 by moving all definitions of the existing Oregon State Plane Coordinate System from ORS Chapter 93 to ODOT's administrative rules and also placing all definitions for the new Oregon Coordinate Reference System into the new OAR.
The new administrative rules concerning the OCRS are now listed on the Secretary of State's State Archives website under ODOT Highway Division, Chapter 34, Division 5 (Oregon Coordinate Systems).
