Changes the discharge capacity limit for domestic wastewater ocean outfalls from "shall not" to "may not" be increased, and prohibits construction of new ocean outfalls and expansion of existing ones.

Requires all functioning reuse systems to meet minimum baseline flow standards of 80 percent by December 31, 2025, and 95 percent by December 31, 2028, measured as a 5-year rolling average.

Mandates utilities with ocean outfall permits as of July 1, 2008, to submit a detailed plan by July 1, 2013, and an amendment and update by December 31, 2018, addressing technical, environmental, and economic feasibility of reuse options.

Prohibits ocean outfall discharge of domestic wastewater after December 31, 2025, except as backup discharge during periods of reduced reclaimed water demand or peak flows, which may not cumulatively exceed 5 percent of baseline flow.

Requires utilities to install functioning reuse systems providing a minimum of 60 percent of baseline flow by December 31, 2025, for irrigation, aquifer recharge, industrial cooling, or other department-authorized reuse purposes.
