City of Ada issued the following announcement on April 9.
At this time, Clean Up Week has been postponed due to COVID-19. We will be working with Al's Disposal, Norman County Landfill, and Norman County Environmental Services to schedule for a later date. As of right now the MPCA will not let the Household Hazzard Waste facility open until the end of May, and the landfill is open by appointment only.
