Announcement of First Public Comment Period and Workshop Draft Technical Support Document on Proposed Public Health Goal for Perchlorate in Drinking Water
Press Release: OEHHA Proposes Revised Public Health Goal for Perchlorate
The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is announcing the availability of the draft technical support document for the proposed Public Health Goal (PHG) for perchlorate in drinking water. The draft document is a revision of the original perchlorate PHG established in 2004, based on new data on environmental exposures to and possible effects of perchlorate, plus further consideration of infants as a susceptible population. These considerations have resulted in the present proposal to decrease the perchlorate PHG from 6 ppb to 1 ppb.
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 45-day comment period. The Office will also hold a public workshop on February 23, 2011 at the Elihu Harris Building, 1515 Clay Street, Oakland, 94612, Room 11, 10 a.m.-12 noon, or until business is concluded. OEHHA follows the requirements set forth in Health and Safety Code Sections 57003(a) and 116365 for conducting the workshop and receiving public input.
Written comments must be received at the OEHHA address below by 5:00 p.m. on February 23, 2011 to be considered during this document revision period. The workshop is provided to encourage a dialogue between OEHHA scientists and the public, to discuss the scientific basis of the proposed PHG, and to receive comments. Following the workshop, OEHHA will evaluate all the comments received, revise the document as appropriate, and make it available for another 30-day comment period. After any subsequent revisions, the final document will be posted on our Web site along with responses to the major comments from the public at the workshop and 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 considerations2. PHGs published by OEHHA are considered by the California Department of Public Health in setting drinking water standards (Maximum Contaminant Levels, or MCLs)3.
