OAR 340-256-0160
Visible Emissions: Alternative Methods of Measuring Visible Emissions

(1)

DEQ may, but is not required to, permit the use of alternative methods of measurement to determine compliance with the visible emissions standards in OAR 340-256-0100 (Visible Emissions: General Requirements, Exclusions) and 340-256-0110 (Visible Emissions: Special Requirements for Excluded Motor Vehicles) if DEQ determines that such alternative methods are demonstrated to be reproducible, selective, sensitive, accurate and applicable to a specific program. If DEQ permits the use of an alternative method of measurement, DEQ shall do so in writing in response to a request under section (2) of this rule.

(2)

Any person desiring to utilize alternative methods of measurement must submit a request to use alternative methods of measurement to DEQ. A request must include such specifications and test data as DEQ may require, together with a detailed specific program for utilizing the alternative methods, sufficient to show that the alternative methods are reproducible, selective, sensitive, accurate, and applicable to a specific program. DEQ may require any additional documentation that it deems necessary.
(3) A person may not undertake a program using an alternative method of measurement without having obtained prior written approval of DEQ.
