OAR 340-142-0100: Sampling/Testing Procedures

All samples used to support and define spill cleanup must be of a type approved by EPA, or the Department, such as those listed in the EPA Office of Solid Waste guidance SW 846. Samples and sampling procedures must be appropriate for the site conditions and materials spilled and be consistent with Department guidance. If the cleanup of spilled materials will be part of a more complex site cleanup, sampling procedures and plans should anticipate greater information needs and be developed and coordinated with the Department.
