The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is announcing the availability of the revised draft technical support document for a proposed Public Health Goal (PHG) for hexavalent chromium in drinking water. This document decreases the proposed PHG to 0.02 parts per billion, versus 0.06 ppb in the first draft posted in 2009; the change is due to consideration of early-in-life exposures for cancer potency. The draft document is posted on the OEHHA web site at www.oehha.ca.gov. OEHHA is soliciting comments on the draft report during a 30-day comment period. OEHHA follows the requirements set forth in Health and Safety Code Sections 57003(a) and 116365 for receiving public input.

OEHHA will evaluate all the comments received and revise the document as appropriate. Written comments must be received at the OEHHA address below by 5:00 p.m. on January 31, 2011 February 15, 2011, to be considered before publication of the final document. 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 1996 (codified at Health and Safety Code, section 116270 et. seq.), requires OEHHA to develop PHGs based exclusively on public health considerations (Health and Safety Code section 116365(c)). PHGs published by OEHHA are considered by the California Department of Public Health in setting drinking water standards (Maximum Contaminant Levels, or MCLs) as required by Health and Safety Code section 116365(a-b).

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.

Public Comments
[03/04/11]

Comments received on OEHHA’s December 2010 draft public health goal (PHG) document for hexavalent chromium appear below. The public comment period on this draft document closed on February 15, 2011. OEHHA’s intent at this time is to review the comments, make any appropriate revisions and finalize the PHG.

OEHHA released its initial public-review draft of the hexavalent chromium PHG in August 2009. OEHHA conducted a public workshop and held a public-comment period on that draft in Autumn 2009. The University of California oversaw an external scientific peer review of the August 2009 draft that had been requested by two members of the public. The peer reviewers’ comments were posted on OEHHA’s web site in September 2010. When the PHG is finalized, OEHHA will post the final document on its web site along with its responses to major comments received during the public comment periods and the peer review.
