West Hollywood

ORDINANCE NO. 01-592

AN ORDINANCE OF THE CITY OF WEST HOLLYWOOD AMENDING THE PLUMBING
CODE TO REQUIRE THE INSTALLATION OF APPROVED SEISMIC GAS SHUTOFF
VALVES IN CERTAIN STRUCTURES AND AMENDING THE WEST HOLLYWOOD
MUNICIPAL CODE.

THE CITY COUNCIL OF THE CITY OF WEST HOLLYWOOD DOES HEREBY RESOLVE,
DETERMINE AND ORDER AS FOLLOWS:

SECTION 1. Findings.


a. Due to local geological conditions, it is generally accepted that the Los Angeles Basin,
including the City of West Hollywood, will experience moderate and severe earthquakes in
the foreseeable future.

b. The danger of fires resulting from earthquakes poses a serious threat to life and property

c. Properly installed seismic gas shutoff valves can reduce the occurrences of fires
stemming from moderate and severe earthquakes and thereby reduce the risks to health,
safety, and welfare caused by such earthquakes.

d. Pursuant to Chapter 4 of part 2.5 of Division 13 of the California Health and Safety Codes
(Health and Safety Code Section 18935 et. Seq.), the Uniform Plumbing Code, 1997
Edition, published by the International Association of Plumbing and Mechanical Officials,
as amended, has been adopted as the California Plumbing Code, 1998 Edition (the
California Plumbing code).

e. By ordinance 99-547U, the City has adopted Title 28 Plumbing Code of the Los Angeles
County Code as amended and in effect on July 1, 1999 as the Plumbing Code of the City of
West Hollywood. Title 28 Plumbing Code of the Los Angeles County Code incorporates the
California Plumbing Code.

f. The City is authorized by Section 18941.5 of the California health and Safety Code to
make such changes in the Plumbing Code of the City of West Hollywood, as are reasonably
necessary because of local climactic, geological, or topographical conditions.

g. The City Council of the City of West Hollywood finds, pursuant to Section 18941.5,
17958, 17958.5 and 17958.7 of the California Health and Safety Code, that the changes
made to the Plumbing Code of the City of West Hollywood by this ordinance are reasonably
necessary because of local geological conditions.

h. The City Council of the City of West Hollywood further finds that the changes made to the
Plumbing Code of the City of West Hollywood by this ordinance establish more restrictive
standards than are currently included in the California Plumbing Code.
SECTION 2. Title 13, Chapter 13.12 of the West Hollywood Municipal Code is amended by
adding thereto a new Section 13.12.035 to read:


13.12.035. Seismic Gas Shutoff Valves.
Notwithstanding the provisions of Section 13.12.010 of this Code, the Plumbing Code is
amended by adding Section 1219 to read as follows:


1219.0. Seismic Gas Shutoff Valves

1219.1. Scope. A seismic gas shutoff valve shall be installed in compliance with the
requirements of this section on each gas fuel line in:

1219.1.1. Any building or structure for which a building permit was first issued on or after
February 15, 2001.

1219.1.2. Any building or structure which is altered or expanded under a building permit
first issued on or after February 15, 2001, when such alteration or addition is valued at more
than $10,000.

1219.1.3.. Any building or structure that is sold to a new owner on or after February 15,
2001, where no less than 12 months have passed since the date of sale. However, when an
individual condominium unit is sold in a building that has multiple gas lines, then the
requirements of this section shall apply only to the line or lines serving the condominium
unit that has been sold.

1219.2. Maintenance. Where the installation of a seismic gas shutoff valve is required by
this section in any building or structure, that seismic gas shutoff valve shall be maintained
for the life of that building or structure or shall be replaced with a valve complying with the
requirements of this section.

1219.3. General Requirements. Where the installation of a seismic gas shutoff valve on a
fuel line is required by this section, that valve must:

1219.3.1. Be mounted rigidly to the exterior of the building or structure containing the fuel
line unless the building official determines that the seismic gas shutoff valve has been
tested and listed for an alternate method of installation.

1219.3.2. Be installed downstream of the gas utility meter, except that a valve may be
installed upstream of the gas utility meter at the discretion of the gas utility if the valve
would otherwise meet the requirements of this section.

1219.3.3. Be listed by an approved testing laboratory and certified by the Office of the
State Architect.

1219.3.4. Have a thirty-year warranty which warrants that the valve is free from defects and
will continue to properly operate for thirty years from the date of operation.

1219.4. Critical Facilities. The requirements of this Section shall not apply to any building
that is used by any public agency for the provision of emergency services, including fire,
police, and similar public safety services.

1219.5. Definitions. For purposes of this section, certain terms shall be defined as follows:

1219.5.1. Downstream of the Gas utility meter shall refer to all customers owned gas piping.

1219.5.2. Seismic Gas Shutoff Valve shall mean a system consisting of a seismic sensing
means and actuating means designed to automatically actuate a companion gas shutoff
means installed in a gas piping system in order to shut off the gas downstream of the
location of the gas shutoff means in the event of a severe seismic disturbance. The system
may consist of separable components or may incorporate all functions in a single body.
The terms "seismically activated gas shutoff valves" and "earthquake sensitive gas shutoff
valves," are synonymous.

1219.5.3. Upstream of the Gas Utility meter shall refer to all gas piping installed by the
utility up to and including the meter and the utility's bypass toe at the connection to the
customer owned piping.

SECTION 3. The City Clerk shall cause this Ordinance to be filed with the California
Building Standards Commission pursuant to Section 17958.7 of the Health and Safety
Code.
