LEGISLATIVE COUNSEL'S DIGEST


SB 606, as amended, Skinner. Water management planning.
(1) Existing law requires the state to achieve a 20% reduction in urban per capita water use in California by December 31, 2020. Existing law requires each urban retail water supplier to develop urban water use targets and an interim urban water use target, as specified.
This bill would require the State Water Resources Control Board, in coordination with the Department of Water Resources, to adopt long-term standards for the efficient use of water, as provided, and performance measures for commercial, industrial, and institutional water use on or before June 30, 2021. The bill would require the department, in coordination with the board, to conduct necessary studies and investigations and make recommendations, no later than October 1, 2020, for purposes of these standards and performance measures. The bill bill, until January 1, 2025, would establish an unspecified number of gallons 55 gallons per capita daily as the initial standard for daily per capita indoor residential water use, and use and, beginning January 1, 2025, would establish 50 gallons per capita daily as the standard for indoor residential water use. The bill would authorize the department, in coordination with the board, to conduct necessary studies and investigations to jointly recommend to the Legislature a standard for indoor residential water use that more appropriately reflects best practices.
The bill would require an urban retail water supplier to calculate an urban water use objective no later than July 1, 2022, and by July 1 every year thereafter, and its actual urban water use by those same dates. The bill would require an urban retail water supplier to submit a report to the department for these purposes by those dates. The bill would authorize the board to issue information orders, written notices, and conservation orders to an urban retail water supplier that does not meet its urban water use objective, as specified.
The bill would impose civil liability for a violation of an order or regulation issued pursuant to these provisions, as specified. The bill would also authorize the board to issue a regulation or informational order requiring a wholesale water supplier, urban retail water supplier, or distributor of a public water supply to provide a monthly report relating to water production, water use, or water conservation.
The bill would require the department department, in consultation with the board, to propose to the Governor and the Legislature, by January 1, 2019, recommendations and guidance relating to the development and implementation of countywide drought and water shortage contingency plans to address the planning needs of small water suppliers and rural communities, as provided. The bill would require the department, in consultation with the board and other relevant state and local agencies and stakeholders, to use available data to identify small water suppliers and rural communities that may be at risk of drought and water shortage vulnerability, no later than January 1, 2019, and would require the department to notify counties and groundwater sustainability agencies of those suppliers or communities.
(2) Existing law establishes procedures for reconsideration and amendment of specified decisions and orders of the board. Existing law authorizes any party aggrieved by a specified decision or order of the board to file, not later than 30 days from the date of final board action, a petition for writ of mandate for judicial review of the decision or order.

Existing law defines “urban water supplier” to mean a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. the act requires the submission of a 2020 plan update by July 1, 2021.
Existing law The act requires an urban water management plan, among other things, to describe the reliability of the water supply and vulnerability to seasonal or climatic shortage, to the extent practicable, and provide data for an average, single-dry, and multiple-dry water years. Existing law The act requires that an urban water management plan provide an urban water shortage contingency analysis that includes, among other things, an estimate of the minimum water supply available during each of the following next 3 water years based on the driest 3-year historic sequence for the agency’s water supply.
This bill would revise and recast these provisions. The bill would require an urban water management plan to be updated on or before July 1, in years ending in 6 and one, incorporating updated and new information from the 5 years preceding the plan update. The bill would require each plan to include a simple lay description of specified information to provide a general understanding of the agency’s plan. The bill would require an urban water management plan to contain a drought risk assessment, as defined, that examines water shortage risks for a drought lasting the next 5 or more consecutive years.
The bill would require an urban water supplier to prepare, adopt, and periodically review a water shortage contingency plan, as prescribed, and as part of its urban water management plan. The bill would require a water shortage contingency plan to consist of certain elements, including, among other things, annual water supply and demand assessment procedures, standard water shortage levels, shortage response actions, and communication protocols and procedures. The bill would require an urban water supplier to make the water shortage contingency plan available to its customers and any city or county within which it provides water supplies no later than 30 days after adoption.
The bill would require an urban water supplier to conduct an annual water supply and demand assessment and submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan by June 1 of each year. The bill would require an urban water supplier to follow, where feasible and appropriate, the procedures and implement determined shortage response actions in its water shortage contingency plan. The bill would also authorize the department to update a certain guidebook, as specified.
(4) Existing law The act requires an urban water supplier to submit copies of its urban water management plan and copies of amendments or changes to the plan to certain entities, including the department, no later than 30 days after adoption, as prescribed. Existing law The act requires the department to prepare and submit to the Legislature, on or before December 31, in the years ending in 6 and one, a report summarizing the status of plans adopted pursuant to the act to the Legislature on or before July 1, 2022, for the 2020 plan, and on or before December 31 in the years ending in 6 and one thereafter, and to provide a copy of the report to each urban water supplier that has submitted its plan to the department.
This bill would require an urban water supplier, if it revises its water shortage contingency plan, to submit to the department a copy of its water shortage contingency plan no later than 30 days after adoption. The bill would require an urban water supplier regulated by the Public Utilities Commission to include its most recent urban water management plan and water shortage contingency plan as part of its general rate case filings.
