Announcement of 15-Day Extension of the Public Comment Period for the Draft Public Health goal for Hexavalent Chromium in Drinking Water

The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is hereby announcing a 15-day extension of the public comment period on the draft technical support document for the proposed Public Health Goal (PHG) for hexavalent chromium in drinking water. The draft PHG document was posted on OEHHA’s web site (www.oehha.ca.gov) on December 31, 2010, and interested parties had been given until January 31, 2011, to submit comments.

With this extension, written comments must be received at the OEHHA address below by 5:00 p.m. on February 15, 2011 to be considered before publication of the final document. OEHHA follows the requirements set forth in Health and Safety Code Sections 57003(a) and 116365 for receiving public input. The final document will be posted on the OEHHA web site along with responses to the major comments received during the public review and scientific comment periods.

The PHG technical support documents provide information on the health effects of contaminants in drinking water. The PHG is a level of drinking water contaminant at which adverse health effects are not expected to occur from a lifetime of exposure. The California Safe Drinking Water Act of 19961 requires OEHHA to develop PHGs based exclusively on public health considerations.2 PHGs published by OEHHA are considered by the California Department of Public Health in setting drinking water standards (Maximum Contaminant Levels, or MCLs).3

If you would like to receive further information on this announcement or have questions, please contact our office at (510) 622-3170 or the address below.
