OAR 340-212-0120: Sampling, Testing and Measurement: Program

(1) As part of its coordinated program of air quality control and preventing and abating air pollution, DEQ may: (a) Require the owner or operator of a stationary source to determine the type, quantity, quality, and duration of the emissions from any air contamination source; (b) Require full reporting in writing of all test procedures and signed by the person or persons responsible for conducting the tests; (c) Require continuous monitoring of specified air contaminant emissions or parameters and periodic regular reporting of the results of such monitoring. (2) DEQ may require an owner or operator of a source to provide emission testing facilities as follows: (a) Sampling ports, safe sampling platforms, and access to sampling platforms adequate for test methods applicable to such source; and (b) Utilities for sampling and testing equipment. (3) Testing must be conducted in accordance with the DEQ Source Sampling Manual, the DEQ Continuous Monitoring Manual], or an applicable EPA Reference Method [NOTE: DEQ Manuals are pubished with OAR 340-200-0035; EPA Reference Methods are found at 40 C.F.R. Part 60, Appendix A], unless DEQ, if allowed under applicable federal requirements: (a) Specifies or approves minor changes in methodology in specific cases; (b) Approves the use of an equivalent or alternative method as defined in division 200; (c) Waives the testing requirement because the owner or operator has satisfied DEQ that the affected facility is in compliance with applicable requirements; or (d) Approves shorter sampling times and smaller sample volumes when necessitated by process variables or other factors. [NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.]
