About the OARs

The OAR Compilation and the Oregon Bulletin

The Oregon Administrative Rules Compilation is an annual print publication containing complete text of Oregon Administrative Rules (OARs) filed through Nov. 15 of the previous year. 

The Oregon Bulletin is a monthly online supplement that contains rule text adopted or amended after publication of the print compilation as well as Notices of Proposed Rule­making and Rulemaking Hearing. The Bulletin also includes certain non-OAR items when they are submitted, such as Executive Orders of the Governor, Opinions of the Attorney General, and Department of Environmental Quality clean-up notices.

The Administrative Rules Unit of the Archives Division, Office of the Secretary of State, publishes the Oregon Administrative Rules Compilation and the online Oregon Bulletin. 

The State Rulemaking Process

A "rule" is "any agency directive, standard, regulation or statement of general applicability that implements, interprets or prescribes law or policy, or describes the procedure or practice requirements of any agency" - ORS 183.310(9). Agencies may adopt, amend, repeal or renumber rules, permanently or temporarily (up to 180 days), using the procedures outlined in the Oregon Attorney General's Administrative Law Manual. 

The Administrative Rules Unit assists agencies with the notification, filing and publication requirements of the rulemaking process.

OAR Citations

Every Oregon Administrative Rule uses the same numbering sequence of a three-digit chapter number followed by a three-digit division number and a four-digit rule number. For example, Oregon Administrative Rules, chapter 166, division 500, rule 0020 is cited as OAR 166-500-0020.

Understanding the History of an Administrative Rule

State agencies operate in an environment of ever-changing laws, public concerns and legislative mandates, which require ongoing rulemaking. To track changes to individual rules and organize the original rule documents for permanent retention, the Administrative Rules Unit maintains history lines for each rule, located at the end of the rule text. OAR histories contain the rule's statutory authority, statutes implemented and dates of each authorized modification to the rule text. 

Changes are listed chronologically in abbreviated form, with the most recent change listed last. In the history line "OSA 4-1993, f. & cert. ef. 11-10-93,"  for example, "OSA" is short for Oregon State Archives; "4-1993" indicates this was the fourth administrative rule filing by the State Archives in 1993; and "f. & cert. ef. 11-10-93" means the rule was filed and certified effective on Nov. 10, 1993.

Locating Current Versions of Administrative Rules

The online version of the OAR Compilation is updated on the first of each month to include all rule actions filed with the Administrative Rules Unit by the 15th of the previous month. 

The annual pri​nted OAR Compilation volumes contain text for all rules filed through Nov. 15 of the previous year. OARs created or changed after publication in the print compilation will appear in a subsequent edition of the online Oregon Bulletin. These are listed by rule number in the Bulletin's OAR Revision Cumulative Index, which is updated monthly. The listings specify each rule's effective date, rulemaking action, and the issue of the Bulletin that contains the full text of the adopted or amended rule.

Filing Adminstrative Rules and Notices

All hearing and rulemaking notices, and permanent and temporary rules, are filed through the online filing system. To expedite the rulemaking process, we encourage agencies to file a Notice of Proposed Rulemaking Hearing specifying hearing date, time and location, and to submit their filings early in the submission period. 

All notices and rules must be filed by the 15th of the month to be included in the next month's Oregon Bulletin and OAR Compilation postings. Filings must contain the date stamp from the deadline day or earlier to be published the following month.

Administrative Rules Coordinators and Delegation of Signing Authority

Each agency that engages in rulemaking must appoint a rules coordinator and file an Appointment of Agency Rules Coordinator form with the Administrative Rules Unit. 

Agencies that delegate rulemaking authority to an officer or employee within the agency must also file a Delegation of Rulemaking Authority form. It is the agency's responsibility to monitor the rulemaking authority of selected employees and keep the forms updated. 

The Administrative Rules Unit does not verify agency signatures as part of the rulemaking process.

Printed volumes of the OAR Compilation are deposited in Oregon's Public Documents Depository Libraries listed in OAR 543-070-0000. You can order complete sets and individual volumes of the printed OAR Compilation from the Archives Division.
