	LEGISLATIVE COUNSEL'S DIGEST


   SB 518, Lowenthal. Building standards: graywater.
   The California Building Standards Law provides for the adoption of
building standards by state agencies by requiring all state agencies
that adopt or propose adoption of any building standard to submit
the building standard to the California Building Standards Commission
for approval and adoption.
   Existing law requires the Department of Housing and Community
Development to propose to the commission the adoption, amendment, or
repeal of building standards relating to hotels, motels, lodging
houses, apartment houses, and dwellings, and the buildings and
structures accessory thereto, except as specified. Existing law
requires the Department of Housing and Community Development, at the
next triennial building standards rulemaking cycle that commences on
or after January 1, 2009, to adopt and submit to the commission for
approval building standards for the construction, installation, and
alteration of graywater, as defined, systems for indoor and outdoor
uses.
   Existing law requires the Department of Water Resources to adopt
standards for the installation of graywater systems. Existing law
terminates the authority of the Department of Water Resources to
adopt graywater standards for residential buildings upon the approval
by the commission of the standards submitted by the Department of
Housing and Community Development.
   This bill would require the commission, as a part of the next
triennial edition of the California Building Standards Code adopted
after January 1, 2011, to adopt building standards for the
construction, installation, and alteration of graywater systems for
indoor and outdoor uses in nonresidential occupancies, in accordance
with prescribed requirements. The bill would terminate the authority
of the Department of Water Resources to adopt standards for graywater
systems in nonresidential occupancies upon adoption of the standards
by the commission.


THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS:

  SECTION 1.  Section 18941.8 is added to the Health and Safety Code,

   18941.8.  (a) As used in this section, "graywater" has the same
meaning as defined in Section 17922.12.
   (b) Notwithstanding Chapter 22 (commencing with Section 14875) of
Division 7 of the Water Code, as a part of the next triennial edition
of the California Building Standards Code (Title 24 of the
California Code of Regulations) adopted after January 1, 2011, the
commission shall adopt building standards for the construction,
installation, and alteration of graywater systems for indoor and
outdoor uses in nonresidential occupancies.
   (c) In adopting building standards under this section, the
commission shall do all of the following:
   (1) Ensure protection of water quality in accordance with
applicable provisions of state and federal water quality law.
   (2) Consider the adopted building standards for the construction,
installation, and alteration of graywater systems for indoor and
outdoor uses in residential buildings.
   (3) Consider existing research available on the environmental

   (d) The commission may revise and update the standards adopted
under this section at any time.
   (e) The commission's adoption of building standards for graywater
systems pursuant to this section shall terminate the authority of the

installation, construction, and alteration of graywater systems in
nonresidential buildings pursuant to Chapter 22 (commencing with
Section 14875) of Division 7 of the Water Code.
  SEC. 2.  Section 14877.1 of the Water Code is amended to read:

at California State University, Fresno, on the installation depth
for subsurface drip irrigation systems.
   (b) The department shall include among the approved methods of
subsurface irrigation, but the approved methods shall not be limited
to, drip systems.
   (c) The department shall revise its graywater systems standards as
needed.
   (d) (1) The authority of the department under this chapter to
adopt standards for residential buildings shall terminate upon the
approval by the California Building Standards Commission of the
standards submitted to that commission pursuant to Section 17922.12
of the Health and Safety Code.
   (2) The authority of the department under this chapter to adopt
standards for nonresidential occupancies shall terminate upon the
adoption of standards by the California Building Standards Commission
pursuant to Section 18941.8 of the Health and Safety Code.
