For the purpose of this section, certain terms shall be defined as follows:
"Downstream of gas utility meter"
refers to all customer-owned gas piping or in liquid petroleum gas installations shall refer to the gas piping on the structure side of the gas regulator.
"Excess flow gas-shut-off device"
means those valves or devices that are not actuated by adoption but are activated by significant gas leaks or over-pressure surges, which can occur when pipes rupture inside the structure. The design of the device provides a proven method to automatically provide for expedient and safe gas-shutoff in an emergency. The design of the device shall provide a capability for ease of consumer or owner resetting in a safe manner. The device is certified by the State Architect or the operational and functional design of the device meets or exceeds the device certified by the office of the State Architect. The determination of whether the operational and functional design of the device is at least equal to the device certified by the State Architect may be made by one of the following: the Independent Laboratory of the International Approval Services (IAS), Underwriter's Laboratory (UL), International Association of Plumbing and Mechanical Officials (IAPMO), or any other recognized listing and testing agency.
"Gas-shut-off device,"
as used in this section, refers to either a seismic gas-shut-off device or excess flow gas-shut-off device.
"Residential building"
means any single-family dwelling, duplex, apartment building, condominium building, townhouse building, lodging house, congregate residence, hotel, or motel.
"Seismic gas-shut-off device"
means a system consisting of a seismic sensing means and actuating means designed to actuate automatically 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 device is certified by the State Architect, and the operational and functional design of the device meets or exceeds the device certified by the office of the State Architect. The determination of whether the operational and functional design of the device is at least equal to the device certified by the State Architect may be made by one of the following: the Independent Laboratory of the International Approval Services (IAS), Underwriters Laboratory (UL), International Association of Plumbing and Mechanical Officials (IAPMO), Office of the State Architect, or any other recognized listing and testing agency.
"Upstream of gas utility meter"
refers to all gas piping installed by the utility up to and including the meter and the utility's bypass fee at the connection to the customer owned piping.
(Ord. 715, 2002)
Approved seismic gas-shut-off devices (motion sensitive) or approved excess flow gas-shut-off devices (non-motion sensitive) shall be installed:
A. 
In any new building construction (commercial, industrial or residential) containing gas piping for which a building permit is first issued on or after the effective date of the ordinance;
B. 
In any existing residential, commercial or industrial building, when any addition or alteration is made to the interior of a building that contains gas piping, and a building permit is required for such work; or
C. 
When any plumbing permit is issued for gas piping.
(Ord. 715, 2002)
A. 
Gas-shut-off devices installed on a building prior to the effective date of this chapter, are exempt from the requirements of this section provided they remain installed on the building or structure and are maintained for the life of the building or structure.
B. 
Gas-shut-off devices installed on a gas distribution system owned or operated by a public utility shall not be subject to the requirements of this chapter (Health and Safety Code Section 19201(b)).
C. 
Installation of gas-shut-off devices is not required for building permits issued for minor and non-structural repairs such as re-roofing, window replacement, siding replacement, decks and any other minor permit as determined by the chief building official.
(Ord. 715, 2002)
A. 
Seismic gas-shut-off devices shall be installed downstream of the gas utility meter or liquid petroleum tank on each fuel gas line where the gas line serves a building; and/or
B. 
Excess flow gas-shut-off devices shall be installed downstream of the gas utility meter or liquid petroleum tank on each fuel gas line where the gas line serves a building and at each gas appliance within a building.
(Ord. 715, 2002)
Gas-shut-off devices installed either in compliance with this chapter or voluntarily, with a permit issued on or after the effective date of this chapter, shall comply with the following requirements:
A. 
Be installed in accordance with the manufacturer's instructions;
B. 
In the case of seismic gas-shut-off devices (motion sensitive) only, such devices must be mounted rigidly to the exterior of the building or structure containing the fuel gas piping. This requirement need not apply if the building and safety division determines that the seismic gas-shut-off device (motion sensitive) has been tested and listed for an alternate method of installation;
C. 
Seismic gas-shut-off devices shall be certified by the State Architect and be listed by an approved listing and testing agency such as IAS, IAMPO, UL or the office of the State Architect;
D. 
Have a thirty-year warranty which warrants that the valve or device is free from defects and will continue to properly operate for thirty years from the date of installation; and
E. 
Where gas-shut-off devices are installed voluntarily or as required by this section, they shall be maintained for the life of the building or structure or be replaced with a valve or device complying with the requirements of this section.
(Ord. 715, 2002)
The building division of the city of Brentwood shall maintain a list of all seismic gas-shut-off devices (motion sensitive) and excess flow gas-shut-off devices (non-motion sensitive) which meet or exceed the requirements of devices certified by the office of the State Architect for installation in the state of California and which comply with the standards and criteria set forth in Health and Safety Code Section 19180 et seq., including quality and design regulation for earthquake actuated automatic gas-shut-off systems (see 24 Cal. Code Regs. Ch. 12-16-1).
