The Ajo Landfill takes up to 5 gallons of oil per month for recycling. For other household hazardous waste, the fact sheet points to the City of Tucson Household Hazardous Waste Collection Program.
Holiday closures
WM's pages for the three transfer stations list these closures: New Year's Day (observed January 2), Presidents Day, Memorial Day, Independence Day, Labor Day, Veterans Day (observed November 10), Thanksgiving and the Friday after, and Christmas Day. Martin Luther King Jr. Day, Good Friday, Christmas Eve and New Year's Eve are listed as open. Conflict: the WM/Pima County fact sheet (updated February 2023) lists Martin Luther King Day as a closure, and the Catalina, Sahuarita and Ryan Field pages also carry a separate note reading "Closed MLK day January 16." The fact sheet gives the same holiday list for the Ajo Landfill. Call ahead on MLK Day.
