Pub. Resources Code, § 43050

(a) On or before January 1, 2008, the board shall conduct a study to define the conditions that potentially affect solid waste landfills, including technologies and engineering controls designed to mitigate potential risks, in order to identify potential long-term threats to public health and safety and the environment. The board shall also study various financial assurance mechanisms that would protect the state from long-term postclosure and corrective action costs in the event that a landfill owner or operator fails to meet its legal obligations to fund postclosure maintenance or corrective action during the postclosure period. The board, on or before July 1, 2009, shall adopt regulations and develop recommendations for needed legislation to implement the findings of the study.

(b) In conducting the study described in subdivision (a), the board shall consult with representatives of the League of California Cities, the County Supervisors Association of California, private and public waste services, and environmental organizations.
