If you decide not to continue with your curbside trash pickup, you will need to opt out of continuing service forty-five (45) days prior to the end of your 6-month free trial by calling Northwest Clean Air Agency at 360-395-9926 or emailing [email protected]. Otherwise, after the trial period ends, the account will be transferred to you and WM will bill you quarterly for ongoing garbage collection service. You can find your opt-out deadline in your welcome letter, or in a letter Northwest Clean Air Agency will be sending prior to your deadline. If you choose to discontinue, your service will be cancelled after your 6-month trial period ends and you will not be billed moving forward.
