Waste Tire Monofill Workshops

On March 30, 2000, the Integrated Waste Management Board conducted the first of two workshops to discuss issues and gather input concerning the impacts of proposed changes in the regulation of underground disposal or underground storage of waste tires. The rules governing all forms of tire monofills, including those at permitted solid waste facilities and those for stand-alone operations, will become part of the solid waste facility regulations. This first workshop will identify pertinent issues to consider. Subsequent workshop(s) will address proposed solutions to the issues developed in the first workshop. The goal of the Board is to insure that changes in any regulatory structure adequately protects public safety without creating an undue burden on the regulated community.

Issues identified for discussion at the first workshop include:

  • How long a phase-in period will be required at existing landfills to implement the concept of a dedicated area for shredded tires?
  • What are the economic impacts of a phase in period?
  • What are the economic and environmental and impacts of creating dedicated areas?
  • Are the proposed technical standards adequate to mitigate fire danger? (Proposed standards are available at www. calrecycle.ca.gov/Rulemaking/Monofill/.)
  • Are there dangers other than fires (illegal disposal, etc.)?
  • What should be the threshold (how many passenger tire equivalents per year are handled) for requiring separate areas at a landfill? Should this threshold be the number of tires handled annually or percentage of waste stream?
  • Is the delivery method significant (large vs small loads)?
  • Is it economically feasible to mine tires from monofills?
  • What roles are played by the local enforcement agencies and Board in the regulation of monofills?
  • Any additional issues presented by the stakeholders.
