Final Draft Child-Specific Reference Doses (chRDs) for School Site Risk Assessment: Cadmium, Chlordane, Heptachlor, Heptachlor Epoxide, Methoxychlor, and Nickel

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is making available for review and comment the Final Draft Report “Development of Health Criteria for School Site Risk Assessment Pursuant to Health and Safety Code Section 901(g): Proposed Child-Specific Reference Dose (chRD) for School Site Risk Assessment--Cadmium, Chlordane, Heptachlor, Heptachlor Epoxide, Methoxychlor, and Nickel.” This document was finalized December 23, 2005.

Health and Safety Code (HSC), Section 901(g) requires the Office of Environmental Health Hazard Assessment (OEHHA), in consultation with the appropriate entities within the California Environmental Protection Agency, to identify those chemical contaminants commonly found at school sites and determined by OEHHA to be of greatest concern based on child-specific physiological sensitivities. HSC §901(g) also requires OEHHA to annually evaluate and publish, as appropriate, numerical health guidance values (HGVs) or chRDs for those chemical contaminants until the contaminants identified have been exhausted.

This public review and comment period follows the requirements set forth in Health and Safety Code Section 57003 for receiving public input.

  • OEHHA has reviewed comments from an external peer review panel assembled by the Office of the President, University of California, and other interested parties in developing the final draft document.
  • The announced availability of this final draft report was October 14, 2005. Because it was not available until November 2, 2005, the previously announced ending date for the comment period of November 14, 2005 is changed. OEHHA requests that comments on the final draft report be delivered to OEHHA by 5:00 p.m. on December 5, 2005.
