IWMA PLANS MORRO BAY HAZARDOUS WASTE FACILITY RELOCATION; ALTERNATE DROP-OFF SITES AVAILABLE

 

San Luis Obispo County, CA – The San Luis Obispo County Integrated Waste Management Authority (IWMA) is moving forward with plans to relocate the Morro Bay Household Hazardous Waste Facility to a new location. The current site, at the former wastewater treatment plant, is slated for demolition and all existing operations must be relocated.  As part of this process, hazardous waste collection operations at the current facility will close, with a final day of residential drop-off on Saturday, July 25, 2026.
