OLYMPIA — The public is invited to review and comment on proposed updates to Washington’s dangerous-waste regulations through Oct. 1.

A public hearing will be held via webinar on Sept. 24 at 2 p.m.

The Department of Ecology updates the dangerous-waste regulations every two to four years to improve waste management. These regulations establish requirements for generators, transporters, and facilities that manage dangerous waste in the state.

If approved, the updates integrate changes to federal hazardous waste regulations would include:

• A rule simplifying waste management at university and college laboratories.

• Changes to import and export rules.

• Adopting technical corrections and a few other minor rules.

Some state requirements will also be updated, including a number of technical and editorial corrections and clarifications. Other state-initiated changes include:

• Clarifying rules for special waste, including a time limit for storing it at transfer stations.

• Updating financial-assurance rules, including new rules at corrective action sites.

• Adopting a federal rule that allows use of enforceable documents in place of a post-closure permit.

• Clarifying rules regarding professional engineers who certify facility construction projects.

• Updating the Chemical Test Methods guidance (Ecology publication #97-407).
