Hazardous Substances Taxes – Activity Fee
The California Department of Tax and Fee Administration (CDTFA) administers four (4) hazardous waste fee programs in cooperation with the Department of Toxic Substances Control (DTSC), pursuant to the requirements of the California Hazardous Substances Tax Law.
Effective 9/13/16, the hazardous waste activity fees are assessed and billed by DTSC (SB 839). Activity fees are assessed for permit applications, permit modifications, renewals of permits, requests for variance or site mitigation assessments or other activities, as notified by DTSC.
The fee is non-refundable, even if the application is withdrawn or the permit or the modification is denied. The fee is tiered based on the permitted level of the facility and the type of permit activity.
