Plain English Breakdown

The candidate explanation includes details that are not explicitly supported by the official source material, such as specific dates for water quality standards remaining in effect and exact funding mechanisms.

Water Quality Control for Non-Navigable Waters

This legislation allows the State Water Resources Control Board to set water quality standards for non-navigable waters and requires stricter enforcement of waste discharge rules.

What This Bill Does

  • Removes limits on the state board's ability to create water quality plans for all types of water in California, including non-navigable waters called 'nexus waters'.
  • Requires existing water quality standards for nexus waters to remain in effect unless a stricter standard is set by regulators.
  • Incorporates nexus waters into federal and state processes that protect water quality.
  • Ensures discharge requirements for point sources discharging into nexus waters follow federal standards.
  • Adjusts civil penalties for violations of waste discharge rules starting January 1, 2026, to fund cleanup efforts.

Who It Names or Affects

  • The State Water Resources Control Board and regional water quality control boards
  • Entities that discharge pollutants into nexus waters

Terms To Know

Nexus Waters
All non-navigable waters in California, excluding navigable waters.
Point Source
A specific source of pollution, like a pipe or ditch, that discharges pollutants into water.

Limits and Unknowns

  • The bill does not specify how the new rules will be enforced.
  • It is unclear what happens if federal and state standards conflict for nexus waters.
  • Details on funding and penalties are subject to legislative appropriation.

Official Summary Text

SB 601, as amended, Allen.
Water: waste discharge.
(1) Under existing law, the State Water Resources Control Board and the 9 California regional water quality control boards regulate water quality and prescribe waste discharge requirements in accordance with the Porter-Cologne Water Quality Control Act (act) and the National Pollutant Discharge Elimination System (NPDES) permit program. Under the act, the State Water Resources Control Board is authorized to adopt water quality control plans for waters for which quality standards are required by the federal Clean Water Act, as specified, and that in the event of a conflict, those plans supersede regional water quality control plans for the same waters.
This bill would
delete the limitation on the state board’s authorization, and instead would
authorize the state board to adopt water quality control plans for
any waters of
the state, which would include
nexus waters, which the bill would define as all waters of the state that are not also navigable, except as specified. The bill would require any water quality standard
applicable to nexus waters, which
that
was submitted to, and approved by, or is awaiting approval by, the United States Environmental Protection Agency or the state board
that applied to nexus waters
as of
January 19, 2025,
May 24, 2023,
to remain in effect,
except where the state board, regional board, or United States Environmental Protection Agency adopts a more stringent standard.
as provided.
The bill would require the state board and regional boards to include nexus waters in all
processes pursuant to the
federal Clean Water
Act,
Act processes,
including, but not limited to, the California Integrated Report and the establishment of total maximum daily loads, as specified.
(2) Existing law requires a regional board, after any necessary hearing, to prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge, except discharges into a community sewer system, with relation to the conditions existing in the disposal area or receiving waters upon, or
into which, the discharge is made or proposed and sets forth what the requirements are to include.
This bill would require the above-described discharge requirements to, in the case of discharges
from any point source
to nexus waters,
implement the relevant federal standards.
implement, at a minimum, the requirements of provisions implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto.
(3) The act authorizes the imposition of civil penalties for violations of certain waste discharge requirements, including violation of a cease and desist order or a cleanup
and abatement order, and requires that penalties imposed pursuant to these provisions be deposited into the Waste Discharge Permit Fund, to be expended by the state board, upon appropriation by the Legislature, for specified purposes related to water quality. For violations of certain other waste discharge requirements, the act imposes specified civil penalties, the proceeds of which are deposited into the continuously appropriated State Water Pollution Cleanup and Abatement Account.
This bill would require, commencing January 1, 2026, and each calendar year thereafter, the state board’s executive director to adjust civil monetary penalties, as specified, including the civil penalties for the above-described provisions. The bill would require moneys collected in accordance with these annual adjustments to be deposited into the Penalty Adjustment Account, that the bill would establish within the Waste Discharge Permit Fund, and upon appropriation by the Legislature,
be expended by the state board for purposes of cleaning up and abating the effects of waste on waters of the state.
(4) Existing law generally provides for enforcement and implementation of the act.
This bill would authorize specified entities, including the Attorney General and the state board, to bring an action to enforce certain provisions related to nexus waters or waste discharge requirements for nexus waters, as provided.
(5) The act provides various provisions related to waste discharge to ensure consistency with the requirements for state programs implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto. The act defines the terms “navigable waters,” “administrator,” “pollutants,” “biological monitoring,” “discharge,” and “point sources” as having the same meanings as in the
Federal Water Pollution Control Act.
This bill would provide that “waste discharge requirements” include waste discharge requirements issued for discharges to nexus waters, and “discharge” includes
discharges from any point source
to nexus waters.
any addition of a pollutant to a nexus water from any point source.
The bill would provide that for purposes of compliance with the Federal Water Pollution Control Act, nexus waters shall be treated as though they are navigable waters and navigable waters of the United States. The bill would require waste discharge requirements adopted or amended for discharges to nexus waters to be adopted pursuant to and in accordance with the requirements of provisions implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto, as specified.
(6) The act requires a person who discharges pollutants or proposes to discharge pollutants to the navigable waters of the United States within the jurisdiction of this state or a person who discharges dredged or fill material or proposes to
discharge dredged or fill material into the navigable waters of the United States within the jurisdiction of this state to file a report of the discharge, except as specified. The act prohibits the discharge of pollutants or dredged or fill material or the operation of a publicly owned treatment works or other treatment works treating domestic sewage by any person, except as authorized by waste discharge requirements or dredged or fill material permits.
This bill would require a person to file a report for discharges to nexus waters. The bill would apply the above-described prohibition to nexus waters.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required
by this act for specified reasons.
