BILL ANALYSIS Ó AB 403 Page 1 CONCURRENCE IN SENATE AMENDMENTS AB 403 (Campos) As Amended July 12, 2011 Majority vote ----------------------------------------------------------------- |ASSEMBLY: |76-0 |(May 26, 2011) |SENATE: |33-0 |(August 31, | | | | | | |2011) | ----------------------------------------------------------------- Original Committee Reference: E.S. & T.M. SUMMARY : Specifies that the primary drinking water standard for hexavalent chromium (chromium 6) is included in the existing expedited Department of Finance (DOF) regulatory review process for drinking water standards. Requires the California Department of Public Health (DPH) to post the report on its progress on developing a drinking water standard for chromium 6 on its Internet Web site. The Senate amendments add Senator Alquist as a principal coauthor and make a minor, technical change. EXISTING LAW requires: 1)Each primary drinking water standard adopted by DPH to be set at a level that is as close as feasible to the corresponding public health goal (PHG), published by the Office of Environmental Health Hazard Assessment (OEHHA), placing primary emphasis on the protection of public health, and that, to the extent technologically and economically feasible, meets specified public health requirements. Requires the PHG to contain an estimate of the level of the contaminant in drinking water that is not anticipated to cause or contribute to adverse health effects, or that does not pose any significant risk to health. 2)DPH to report to the Legislature on its progress in developing a primary drinking water standard for chromium 6 by January 1, 2003. 3)DPH to establish a primary drinking water standard for chromium 6 on or before January 1, 2004. 4)DOF, for any proposed regulation that relates to the maximum AB 403 Page 2 contaminant level for primary or secondary drinking water standards, to take no longer than 90 days to review and act upon that rule or regulation. 5)DPH and the Office of Administrative Law to proceed with all other applicable procedures in connection with the adoption of proposed regulations should DOF take longer than 90 days to act upon the proposed drinking water standard regulations. AS PASSED BY THE ASSEMBLY , this bill was substantively similar to the version passed by the Senate. FISCAL EFFECT : According to the Assembly Appropriations Committee, negligible state costs, if any. COMMENTS : Need for the bill : The author argues that, "In 2001, Senator Ortiz introduced SB 351, Chapter 602, which required DPH to adopt a primary drinking water standard for hexavalent chromium by January 1, 2004. However, DPH never complied due to the lack of a Public Health Goal. DPH is tasked to provide a Maximum Contaminant Level (MCL) based primarily on the Public Health Goal and other regulatory and feasibility processes. This bill will simply ensure that DPH complies in a timely manner and sets a standard that has been long overdue in order to ensure our communities are provided with drinking water that is safe and meets stringent requirements." Chromium 6 : According to OEHHA, chromium 6 is a heavy metal that is commonly found at low levels in drinking water. Chromium 6 is known to be a potent carcinogen when inhaled. It was recently found to also cause cancer in laboratory mice and rats that were exposed through drinking water. According to the Environmental Working Group, in California, chromium 6 was detected in 2,208 out of the more than 7,000 tap water systems analyzed as of 2008 (DPH 2009). Current status of the chromium 6 maximum contaminant level (MCL) : California has long recognized the public health risks of exposure to chromium 6. In 1977, California established a drinking water standard, or MCL, for total chromium expressly to address exposure to chromium 6. AB 403 Page 3 Health and Safety Code (HSC) Section 116365(a) requires DPH to establish an MCL at a level as close as is technically and economically feasible to the contaminant's PHG. In March 2001, the Department of Health Services, DPH's predecessor agency, requested that OEHHA prepare a PHG for chromium 6 in preparation for a MCL on chromium 6 alone. SB 351 (Ortiz), Chapter 607, Statutes of 2001, requires DPH to adopt an MCL for chromium 6 by January 1, 2004 (HSC Section 116365.5). On July 27, 2011, OEHHA announced that it had set the final PHG for chromium 6 at 0.02 parts per billion (ppb), which is the same level as the draft that was released for public comment in December 2010. State law requires OEHHA to set PHGs to provide scientific guidance to DPH in developing enforceable drinking water standards. By law, DPH must set the eventual standard, or MCL, as close to the PHG as economically and technically feasible. Analysis Prepared by : Shannon McKinney / E.S. & T.M. / (916) 319-3965 FN: 0002503
