Comparison: State vs. Federal

Rules. In addition to complying with the federal biennial reporting rules, large quantity generators (LQGs) and owners and operators of treatment, storage, and disposal facilities (TSDFs) must submit an annual report to DEQ. Oregon's annual report requirements also apply to small quantity generators (SQGs) and hazardous waste recyclers.

The annual reports submitted by LQGs and TSDF owners and operators fulfill the federal reporting requirements. DEQ compiles the information from its annual reports to complete the federal biennial reports, due to the U.S. Environmental Protection Agency's Region 10 office by March 1 of every even-numbered year. The federal biennial report requirements and form are reviewed in the national section BIENNIAL REPORT.

Used oil processors in Oregon must file an annual report with DEQ, tracking quantities of used oil accepted for processing or refining. Refer to the state section USED OIL MANAGEMENT for more information.
