Existing law requires the Department of Toxic Substances Control to adopt regulations for the identification and management of hazardous wastes. Existing law authorizes the department to adopt regulations designating end-of-life photovoltaic modules that are identified as hazardous waste as a universal waste and subject to regulations applicable to universal waste management. Federal regulations identify solid wastes which are subject to regulation as hazardous wastes. Federal regulations exclude from the definition of solid waste for that purpose hazardous secondary material that is generated and then transferred to another person for the purpose of reclamation under specified circumstances. This bill would require the department, on or before July 1, 2028, to convene one or more public workshops for interested parties to comment on the applicability of the above-described federal regulations to hazardous waste streams, including, but not limited to, solar photovoltaic modules, generated in California. The bill would require the department, on or before July 1, 2029, to consider the feedback received and evaluate the applicability of those federal regulations to end-of-life solar photovoltaic modules as an alternative to one or more of the state standards governing hazardous waste and universal waste management. The bill would authorize the department, based on findings of the evaluation, to adopt, by regulation, the federal regulations, subject to revision as necessary, and apply them to end-of-life solar photovoltaic modules that are identified as hazardous waste under existing state law.
