0 0 ORDER NO. R5-2006-0054 -13- INDIVIDUAL 13 - INDIVIDUAL DISCHARGER CONDITIONAL. WAIVER OF WASTE DISCHARGE REQUIREMENTS FOR DISCHARGES FROM IRRIGATED LANDS 58. This Order is not a new project that requires preparation of any new environmental documents to comply with CEQA. It is a renewal of an existing project, with modifications. These findings, nevertheless, evaluate whether a subsequent environmental document is required. Public Resource Code section 21166 and Title 14 California Code of Regulations section 15162 (CEQA Guidelines) specifies that when the lead agency has adopted a negative declaration for a project, the agency is not required to prepare a subsequent environmental document unless the lead agency determines, on the basis of substantial evidence in the light of the whole record, that, in summary: 1) substantial changes are proposed in the project that involve new significant environmental impacts; 2) substantial changes occur with respect to the circumstances of the project; or 3) new information of substantial importance which was not previously known shows that the project will have significant effects. None of the circumstances requiring preparation of subsequent environmental document has occurred. 59. The project is the renewal of Conditional Waivers originally adopted in 2003; it is not a new project. Substantial changes are not proposed in the project or with respect to the circumstances of the project that would involve new significant environmental effects or a substantial increase in environmental effects. This Order will require actions to protect water quality as compared to Resolution No. R5-2003-0105. These actions include development, implementation of management practices, and implementation of Management Plans as requested by the Executive Officer and enhanced reporting and communications with regard to exceedances of applicable water quality standards. 60. Since the adoption of Resolution No. R5-2003-0105 and the Negative Declaration, new information has become available to the lead agency. Central Valley Water Board staff has compiled two years of water quality monitoring data from Central Valley Water Board sources, Coalition Groups, Water Districts and others within the Sacramento River, San Joaquin River, and Tulare Lake Basins. Additional information has been provided by contract with the University of California (UC). Water quality monitoring data from Coalition Groups and Individual Dischargers identified exceedances of applicable water quality standards. Monitoring conducted through a contract with the University of California and monitoring from Coalition Groups and individual dischargers have identified problem sites in many water bodies since 2004. Information from about 110 monitoring sites through UC monitoring, about 90 monitoring sites from Coalitions, and 24 monitoring sites with Irrigation Districts is providing data that will prove invaluable in characterizing the effects of irrigated agriculture on water bodies in the Central Valley. About 1,758 samples were collected by all of the Irrigated Lands Coalitions, and approximately 739 through the UC contract. Coalition monitoring consisted primarily of toxicity testing (Phase n and represents approximately 20 percent of the water bodies within most individual coalition boundaries at this time. Coalitions are required to expand their monitoring sites each year to be able to assess all water bodies within their boundaries, as well as to expand into Phase II monitoring which will include pesticides, nutrients and general water quality parameters.
