The San Luis Obispo County Integrated Waste Management Authority (IWMA) is a government entity formed through a Joint Powers Authority governed by a 13-person Board of countywide elected officials from San Luis Obispo County and the Cities of Arroyo Grande, Atascadero, Grover Beach, Morro Bay, Paso Robles, Pismo Beach, San Luis Obispo and the Community Service Districts.
These jurisdictions formed the IWMA in 1994 to plan and implement regional solid waste and hazardous waste programs. The IWMA Board oversees the IWMA office and its mission to manage hazardous waste, universal waste, solid waste, green/food waste, and recycling for San Luis Obispo County.
