BILL ANALYSIS Ó AB 1707 Page 1 CONCURRENCE IN SENATE AMENDMENTS AB 1707 (Wilk) As Amended August 6, 2014 Majority vote ----------------------------------------------------------------- |ASSEMBLY: |73-0 |(May 23, 2014) |SENATE: |36-0 |(August 13, | | | | | | |2014) | ----------------------------------------------------------------- Original Committee Reference: E.S. & T.M. SUMMARY : Requires the State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (Regional Water Boards) to post on its Internet Web site a copy of the external scientific peer review conducted for proposed total maximum daily loads (TMDLs) requirements of the state board or a regional board. The Senate amendments add the Regional Water Board's scientific peer reviews to documents required to be posted on the State Water Boards Internet Web site. EXISTING LAW : 1)Under the federal Clean Water Act (Act), requires the state to identify those waters within its boundaries that are not sufficiently protected by state and federal water quality standards (identified as "impaired water bodies"), to rank such waters based upon the severity of their pollution, and to establish TMDLs for pollutants found in those waters. 2)Under the Porter-Cologne Water Quality Act: a) Requires each Regional Water Board to adopt a water quality control plan for its region that provides for the reasonable protection of the beneficial uses of waters in that region. Requires the implementation of water quality objectives to include a broad description of the actions necessary to achieve such objectives. b) Establishes an external scientific peer review process of the scientific basis of any proposed regulatory requirements by boards, departments, and offices in the California Environmental Protection Agency (CalEPA). AB 1707 Page 2 Requires the external scientific peer review to specifically include those policies adopted by the State Water Board to implement regional basin water quality plans. AS PASSED BY THE ASSEMBLY , this bill required the State Water Board to post on its Internet Web site a copy of the external scientific peer review conducted for proposed to TMDLs requirements. FISCAL EFFECT : According to the Senate Appropriations Committee, pursuant to Senate Rule 28.8, negligible state costs. COMMENTS : Need for the bill: According to the author, "AB 1707 would require the State Water Quality Resource Control Board to post a copy of the external scientific peer review to their Web site - a website that already exists. Assembly Bill 1707 will alleviate concerns regarding the assessment of and access to the scientific peer review for TMDLs, and will implement a more effective strategy through mandatory reporting of the peer review and mandatory online availability for interested parties. It is important that sound science be employed before requiring ratepayers to fund these mitigations and AB 1707 will be an incremental step in accomplishing that goal." TMDLs: TMDLs have been required by the Act since it was first passed in 1972. Section 303(d) of the Act requires states to identify all the water bodies that do not meet applicable water quality standards; and, for those "impaired" water bodies, states must establish TMDLs. TMDLs are standards for evaluating water quality in which a beneficial use is considered with reference to the condition of a water body, (e.g., concentration and toxic effect.) Upon establishment of TMDLs by the State or United States Environmental Protection Agency (U.S. EPA), the state is required to incorporate, or reference, TMDLs into the State Water Quality Management Plan (Basin Plan). The Basin Plan and applicable statewide plans serve as the State Water Quality Management Plans governing the watersheds under the jurisdiction AB 1707 Page 3 of the Regional Water Boards. Scientific peer review for CalEPA regulations: The current scientific peer review requirement provided in Health and Safety Code Section 57004 is that all CalEPA organizations submit for external scientific review the scientific basis and scientific portion of all proposed policies, plans, and regulations. The peer reviewer's responsibility is to determine whether the scientific findings, conclusions, and assumptions are based upon sound scientific knowledge, methods, and practices. Health and Safety Code Section 57004 requires external scientific peer review for certain water quality control policies. Regional Water Boards are required to receive external scientific peer review of the scientific basis of any proposed amendment to the Basin Plan. According to the CalEPA, there are several circumstances when work products do not require scientific peer review requirements. These work products have been peer reviewed by a recognized expert or expert body. Additional review is not required if a new application of an adequately peer reviewed work product does not depart significantly from its scientific approach. These types of work projects would include standards developed by the U.S. EPA, which CalEPA adopts. These U.S. EPA standards are presumed to have been sufficiently peer reviewed unless additional peer review is required by law.
