WHAT THE MEASURE IS SHOWING
General NPDES permits are used broadly across the state, with the majority of permitted facilities regulated under a general wastewater NPDES permit are located in the San Francisco Bay Region (Region 2), the Los Angeles Region (Region 4), the Central Valley Region (Region 5) and the San Diego Region (Region 9). As of the end of Fiscal Year (FY) 2017-18, 1,408 facilities that are regulated under a general wastewater NPDES permit are considered current (91 percent) as the permit has been updated within the last five years. As of June 30, 2018, 134 facilities are operating under permits past their expiration/review date (i.e., not updated). The permit backlog remains to be addressed and may represent an additional workload for FY 2018-19. The permit backlog varies among the Regional Water Boards, however more than 90 percent of facilities in the North Coast Region (Region 1), San Francisco Bay region (Region 2), Central Coast Region (Region 3), Los Angeles Region (Region 4), Central Valley Region (Region 5) and Colorado River Region (Region 7) are operating under current general NPDES permits.WHY THIS MEASURE IS IMPORTANT
In order to ensure that discharges to surface waters do not adversely affect the quality and beneficial uses of such waters, NPDES permits must be reviewed and revised to reflect new standards and requirements (such as new TMDLs and other water quality plans and policies adopted) and updates to monitoring and reporting requirements (reflecting previous facility performance and compliance history). NPDES permits expire five years after issuance and are required to be reissued (i.e., renewed) every five years or less (40 CFR Part 122.46 and California Water Code section 13380). Typically, permit requirements remain in effect until the permit is reissued, however NPDES permits may also be revoked or terminated. Revising and reissuing permits for minor facilities requires a significant amount of time and resources, and is considered a good indicator of overall program performance.TECHNICAL CONSIDERATIONS
