Land Disposal Program


Wastes Allowed for Discharge at Disposal Facilities

For a current list of waste types accepted by a facility, we recommend reviewing the facility’s public website or contacting them directly prior to arrival.

This page is under development.

An interactive landfill waste acceptance mapping tool is currently under development. The tool will contain operating commercial Class I, II, and III landfills and waste acceptance information. Landfills are classified as follows: Class I accepts hazardous and nonhazardous wastes; Class II may accept “designated” and nonhazardous wastes; and Class III may accept nonhazardous municipal wastes.

There are currently three databases maintained by the State of California that can be utilized to locate operating commercial landfills and their regulatory documents in California:

The California Integrated Water Quality System database for the State Water Resources Control Board. A facility’s Waste Discharge Requirements can be found here, containing a list of authorized waste materials a landfill may accept.

State Water Resources Control Board’s data management system for sites that impact, or have the potential to impact, water quality in California, with emphasis on groundwater. Waste Discharge Requirements and other Water Board regulatory documents are located in the GeoTracker database.

The Solid Waste Information System database for the California Department of Resources Recycling and Recovery (CalRecycle). To search for transfer stations, material recovery facilities, composting sites, transformation facilities, waste tire sites and closed disposal sites, please see the CalRecycle SWIS database.


A Waste Discharge Requirement (WDR) contains a list of wastes the landfill is authorized to accept by the Regional Water Quality Control Board. The landfill operator may choose not to accept certain wastes they are permitted to accept. Additionally, the landfill’s Solid Waste Facility Permit, issued by the local enforcement agency (LEA) and CalRecycle, may also restrict the disposal of certain waste types. Prior to arriving with waste, please contact the landfill directly for the most up-to-date list of waste types accepted there

If you have any other questions, please contact the facility or the appropriate Regional Water Quality Control Board. Visit the Land Disposal Program webpage for more information and to find a list of State and Regional Water Quality Control Board contacts.
