	LEGISLATIVE COUNSEL'S DIGEST


   SB 518, as amended, 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  to the commission
 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.
   Vote: majority. Appropriation: no. Fiscal committee: yes.
State-mandated local program: no.


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

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

adopted by the International Association of Plumbing and Mechanical
Officials, as the starting point for the building standards and amend
those standards as necessary.
   (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

   (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.
