Whenever possible, individuals and organizations should implement practices that reduce or eliminate wastes at the source.
If you do end up with hazardous waste, follow the guidelines below for safe disposal or use Metro's guide to hazardous waste disposal.
Septage is a liquid and solid material removed from septic tanks or other holding tanks for domestic sewage. Chemical toilet waste is a liquid and solid material removed from portable chemical toilets.
Septage haulers can be licensed to discharge septage at the Durham or Rock Creek Treatment Plants. Those who want to be licensed or who have questions about whether certain septage will be accepted at the District's plants should contact our Environmental Services Division at 503.681.5133. (Material containing industrial waste is not accepted.)
Every liquid waste hauler needs to complete and submit the Liquid Waste Hauler Permit Application (PDF, 49KB) to receive a permit.
We have created a short video (4:33) demonstrating how to use the automated liquid waste receiving station at the Durham treatment facility.

All painting jobs create wastes that can harm humans, waterways, fish and other wildlife if handled or disposed improperly. Paints and paint waste can enter storm drains from runoff or improper disposal. Storm drains carry untreated pollutants directly into streams and rivers, harming aquatic plants, animals, fish and those who eat the fish.
Aside from causing environmental damage, improper disposal violates Oregon law. OAR 340-61-020 (1), OAR 340-45-015 (1) (a) & (b), and ORS 459.205 (1) all prohibit improper disposal of wastes and contamination of waters and provide for civil and criminal penalties for violators. Most painters manage wastes responsibly, but sometimes disposal options can be confusing. This brochure is designed to help you prevent, reduce, recycle or safely dispose of common painting wastes. The result will be happier customers who appreciate your concern for their property and a safer environment.
