Or. Admin. R. 340-256-0358 – Emission Control System Inspection: Emissions Control Test Method for Self-Service Testing Program

This rule documents the Self-Service test method.

(1) DEQ may provide a testing method whereby the vehicle owner or their representative will perform the emissions test. The test performed will be either a remote sensing optical quantification of the tailpipe pollutants, a remote or computer connected OBD test, or other means approved under section (4) of this rule.
(2) Before implementing Self-Service Testing under this rule, DEQ must establish specific Self-Service Testing processes in DEQ’s policies and procedures documents, including:
1. (a) The test techniques to be used for Self-Service Testing;
2. (b) Procedures for identifying the vehicle that will be subjected to Self-Service testing;
3. (c) Procedures for protecting the Self-Service test process from vandalism and cheating; and
4. (d) Testing standards for the Self-Service technique that will be used.
(3) If DEQ uses the optical attenuation method for Self-Service Testing, 1975 and newer model year vehicles are eligible for Self-Service Testing. If DEQ uses broadcast data or hardwire cable connection from vehicles’ OBD systems for Self-Service Testing, 1996 and newer model year vehicles are eligible for Self-Service Testing.
(4) If DEQ develops and implements additional test methods for use in the Self-Service Testing program, DEQ must develop documentation that such method will provide equal or greater accuracy in identifying vehicles that would pass or fail the otherwise required emission test.
