The San Luis Obispo County Integrated Waste Management Authority (IWMA) is a regional agency, formed in 1994. It was created in an agreement between Arroyo Grande, Atascadero, Paso Robles, Grover Beach, Morro Bay, Pismo Beach, and San Luis Obispo and the County of San Luis Obispo.
The emphasis of SLO County IWMA is to meet the requirements of the California Integrated Waste Management Act of 1989 (AB 939). This act requires each city and county in California to divert at least 50% of its solid waste from landfills by the year 2000. Subsequent legislation requires waste diversion to increase to 75% by 2020.
The San Luis Obispo County IWMA works on effective management and solutions in the areas of solid waste, recycling, household hazardous waste and other related issues. To best meet these objectives, IWMA offers a countywide school education program to teachers in grades K-12. These free programs include topics such as recycling, vermicomposting, household hazardous waste, zero waste and a field trip to the Cold Canyon Landfill and Recycling Facility.
