SBDDW-16-02 Surface Water Augmentation (SWA) Regulations

Background

Water Code section 13562 requires the State Water Board to adopt uniform water recycling criteria for surface water augmentation (SWA regulations) on or before December 31, 2016, if an Expert Panel has made a finding that the proposed criteria (regulations) would adequately protect public health. For more background information, please see the Initial Statement of Reasons (ISOR) provided below.

Water Code section 13562(b) requires adoption of Surface Water Augmentation regulations to be in accordance with the requirements of the Administrative Procedures Act (APA).

External Scientific Peer Reviews

The proposed regulations went through two separate external review processes:

  • Health and Safety Code section 57004 requires a regulation proposed for adoption by the State Water Board, which establishes requirements for the protection of public health or the environment, to undergo an external scientific peer review of the basis of the scientific portions of the regulation. The State Water Board received the completed scientific peer review on June 10, 2016. Information related to the scientific peer review may be found here and is discussed further in the Initial Statement of Reasons provided below. The scientific peer reviewers were independent of the Expert Panel.
  • As previously noted, Water Code section 13562 mandates that the State Water Board shall not adopt uniform water recycling criteria for surface water augmentation unless and until the Expert Panel has adopted a finding that the proposed criteria would adequately protect public health. Therefore, the Expert Panel reviewed the proposed SWA regulations and, by way of a document dated October 31, 2016, the Expert Panel made a finding that the proposed uniform water recycling criteria for surface water augmentation adequately protects public health. Further information related to the Expert Panel's finding, as well as biographies of the Expert Panel members, may be found in the Initial Statement of Reasons provided below.

Public Hearings and Treatment Technology Findings for Surface Water Augmentation Projects

Pursuant to Health and Safety Code section 116551(b), prior to issuing a permit to a public water system or amending a valid existing permit for the use of reservoir as a source of supply that is directly augmented with recycled water (i.e., surface water augmentation), three duly noticed public hearings are required to be held in the area where the recycled water is proposed to be used or supplied for human consumption, for receiving public testimony on that proposed use.  In addition, the State Water Board must ensure a project’s treatment technology information is available to the public at least ten days prior to a public hearing for a project.

Information regarding mandated public hearings for surface water augmentation projects, as well as access to the proposed treatment technology reports, is provided in the table below.  For the projects listed, the State Water Board has evaluated the projects’ proposed treatment technology and determined that the recycled water will meet all applicable primary and secondary drinking water standards and poses no significant threat to public health.  The determination does not constitute final approval of a project.
