BILL ANALYSIS Ó AB 403 Page 1 Date of Hearing: May 18, 2011 ASSEMBLY COMMITTEE ON APPROPRIATIONS Felipe Fuentes, Chair AB 403 (Campos) - As Amended: April 14, 2011 Policy Committee: Environmental Safety and Toxic Materials Vote: 9-0 Urgency: No State Mandated Local Program: No Reimbursable: No SUMMARY As proposed to be amended, this bill declares that if the Department of Public Health's (DPH) proposed regulation to establish a hexavalent six drinking water standard is required to be reviewed by the Department of Finance and Finance takes longer than 90 days to complete the review, then DPH and the Office of Administrative Law (OAL) shall proceed with actions required in the adoption of the proposed regulation. FISCAL EFFECT Negligible state costs, if any. COMMENTS 1)Rationale. The author contends this bill will ensure DPH complies with its existing legal obligation to adopt a drinking water standard for hexavalent chromium. 2)Background. a) State Regulation of Drinking Water. Two state entities-the Office of Environmental Health Hazard Assessment (OEHHA) and DPH-are responsible for assuring that the state's drinking water is safe, pure, and potable. i) OEHHA scientifically assesses the risks to human health posed by contaminants that may be found in the state's public drinking water systems and are regulated or proposed to be regulated under DPH's safe drinking AB 403 Page 2 water regulatory program. Based on that scientific assessment, OEHHA adopts contaminant-specific goals, known as PHGs (public health goals), that specify, based solely on public health considerations, the maximum levels of concentration at which various contaminants can be found in drinking water without adversely affecting human health. ii) DPH manages the risk to human health identified in OEHHA's PHGs (which are advisory) by setting primary drinking water standards (also known as "maximum contaminant levels" or "MCLs"). Statute requires DPH to set its MCL for each regulated contaminant as close as is technologically and economically feasible to the corresponding PHG. In this way, OEHHA's PHGs form the scientific basis of DPH's regulation of drinking water to ensure public health and safety: MCLs specify the maximum level of each contaminant allowable in the state's public drinking water systems regulated by DPH. b) Statute Requires DPH to Adopt Standard for Hexavalent Chromium. According to OEHHA, hexavalent chromium, also known as chromium six, is a heavy metal commonly found at low levels in drinking water. It can occur naturally but can also enter drinking water sources by historic leaks from industrial plant hazardous waste sites. Other sources also contribute to the amount of hexavalent chromium in groundwater. The policy committee analysis notes that chromium six is a potent carcinogen, when inhaled. It was recently found to also cause cancer in laboratory mice and rats that were exposed through drinking water. SB 351 (Ortiz, Chapter 602, Statutes of 2001) requires the State Department of Health Services (DPH's predecessor) to adopt a primary drinking water standard for hexavalent chromium by January 1, 2004, and requires a report on the progress of developing the standard to the Legislature by January 1, 2004. To date, OEHHA has released only a draft PHG for hexavalent chromium; without a final PHG, DPH cannot adopt its drinking water standard. Some stakeholders believe OEHHA will adopt a final PHG for hexavalent chromium later this year; however, OEHHA could not confirm this rumor. AB 403 Page 3 3)Amendments Seek to Simplify Bill. As passed by the policy committee, this bill would have extended to 2013 the date by which DPH is required to pass its drinking water standard for hexavalent chromium, required DPH to report to the Legislature on delays, and dismissed required review of the proposed standard by any other state agency if the agency had not done so within 90 days of DPH's request for review. The author has submitted proposed amendments that maintain the original 2003 due date for the standard and waive the required review of the proposed standard by Finance if Finance takes longer than 90 days to complete the review.
