Oregon Septic Hauling Compliance Guide

Oregon stands out for requiring a DEQ-approved Septage Management Plan before you can get licensed. Under OAR 340-071-0600, every pumping business must submit a plan to the Oregon Department of Environmental Quality demonstrating how septage will be collected, transported, and disposed of. Without an approved plan, there is no license.

Licensing runs on a triennial cycle — every three years — with a $5,000 bond required for pumper-only operations and $15,000 for combined installer/pumper licenses. Oregon also mandates 3-year record retention, shorter than the 5-year federal default but still enforceable during audits.

Vehicle requirements in Oregon are among the more specific in the country. Every truck needs DEQ-issued labels on the front, rear, and both sides. In addition, the business name must be displayed in letters at least 3 inches tall on both sides of the vehicle, and the tank capacity must be visible. Pump trucks must have a minimum 550-gallon tank, while chemical toilet service vehicles need at least 150 gallons.

Manifests must include eight fields: generator name and address, waste type, gallons pumped, vehicle ID, date of service, origin address, and destination address. That explicit origin and destination tracking goes beyond what many states require and means every load has a documented chain of custody from pickup to disposal. Grease trap waste falls under the same DEQ pumper license and Septage Management Plan — no separate grease license is needed.
