Summary

Official abstract published by the California legislature· summary

(1) The California Integrated Waste Management Act of 1989, administered by the Department of Resources Recycling and Recovery (CalRecycle) , generally regulates the disposal, management, and recycling of solid waste, as defined. The act authorizes CalRecycle to certify a local enforcement agency and requires CalRecycle and certified local enforcement agencies to perform specified functions with regard to the regulation of solid waste management, including issuing and enforcing solid waste facility permits. The act prohibits a person from operating a solid waste facility without a solid waste facilities permit, as provided. The California Global Warming Solutions Act of 2006 charges the State Air Resources Board with monitoring and regulating sources of emissions of greenhouse gases that cause global warming in order to reduce emission of greenhouse gases. The act requires the state board to adopt rules and regulations to achieve the maximum technologically feasible and cost-effective greenhouse gas emissions reductions, as provided. This bill would require the owner or operator of a solid waste landfill, as defined, to, among other things, notify the Department of Resources Recycling and Recovery if a subsurface elevated temperature event occurs. The bill would define "subsurface elevated temperature event" to mean an event where subsurface gas or waste temperatures at a solid waste landfill persistently exceed 131 degrees Fahrenheit over a substantial area and meets other performance criteria, as determined by the department. The bill would authorize the department to require the owner or operator of a solid waste landfill experiencing a subsurface elevated temperature event to create a corrective action plan that includes, but is not limited to, a cost assessment for fully implementing the corrective action plan. The bill would authorize the department or a local enforcement agency to impose an administrative civil penalty of $100,000 per day for failing to comply with these requirements, as provided. The bill would require all penalties collected to be deposited into the Landfill Subsurface Fire Mitigation Community Fund, which the bill would create in the State Treasury. The bill would continuously appropriate moneys in the fund to the California Alternative Energy and Advanced Transportation Financing Authority, to be paid to counties in which a subsurface elevated temperature event occurred to mitigate harm to a person or community affected by a subsurface elevated temperature event and to be paid to the authority for its costs of implementation. The bill would require the authority to develop guidelines for dispersing these funds, as specified. The bill would authorize the department to become the enforcement agency for a solid waste landfill experiencing a subsurface elevated temperature event, as specified. This bill would authorize the Secretary for Environmental Protection to select and coordinate a multiagency coordination group to investigate and provide recommendations on how to achieve resolution of a subsurface elevated temperature event, as specified. The bill would require a local health department to initiate community health needs assessments to identify and collect information regarding the effects of a subsurface elevated temperature event on an affected community and to share the findings, as provided. By requiring a local health department and a local air pollution control district to perform additional duties, the bill would impose a state-mandated local program. The bill would, upon request by a multiagency coordination group, require the owner or operator of a solid waste landfill that experiences a subsurface elevated temperature event to implement an air monitoring and sampling plan, as specified. The bill would require the owner and operator of a solid waste landfill that experiences a subsurface elevated temperature event to reimburse the members of a multiagency coordination group and the local health department for all reasonable and necessary expenses incurred, as specified. The bill would authorize the department to adopt regulations to implement and enforce them as emergency regulations, as specified. (2) This bill would declare its provisions to be severable. (3) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
