As provided in Title 13 of the California Code of Regulations, Section 2485(c):
(a) 
Idling: The driver of any vehicle subject to Title 13 of the California Code of Regulations, Section 2485 and this Chapter shall comply with the following requirements, except as noted in Section 3-04-1030 below:
(1) 
The driver shall not idle the vehicle’s primary diesel engine for greater than 5.0 minutes at any location.
(2) 
The driver shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5.0 minutes at any location when within 100 feet of a restricted area.
(b) 
Use of Alternative Technologies:
(1) 
The driver shall not operate an internal combustion APS on any vehicle equipped with a 2007 and subsequent model year primary diesel engine unless the vehicle is:
(A) 
Equipped with an APS meeting the emissions performance requirements found in sub-section (c)(1)(a) of this section; and
(B) 
The vehicle is equipped with a label meeting the requirements pursuant to section 35.B.4 of the "California Exhaust Emission Standards and Test Procedures for 2004 and Subsequent Model Heavy-Duty Diesel Engines and Vehicles," as incorporated by reference in Title 13, California Code of Regulations, Section 1956.8(b).
(2) 
The driver shall not operate a fuel-fired heater on any vehicle equipped with a 2007 and subsequent model year primary diesel engine unless the fuel-fired heater meets the emissions performance requirements found in subsection (c)(2), below;
(3) 
The driver of a vehicle equipped with a 2006 or older model year primary diesel engine may use and operate in California any certified internal combustion APS with or without the additional PM control specified in subsection (c)(1)(A) or any other certified alternative idling reduction technology.
(c) 
Compliance Requirements: As an alternative to idling the primary engine, diesel engines/vehicles may, as an option, be equipped with alternative technologies, as listed and defined below in (1), (2), and (3) of this subsection. If so equipped, these technologies are subject to the following requirements:
(1) 
Internal Combustion APS.
(A) 
In order to operate in California, an APS utilizing an internal combustion engine must comply with applicable California off-road and/or federal non-road emission standards and test procedures for its fuel type and power category. In addition, diesel-fueled APSs installed on vehicles equipped with primary engines certified to the 2007 and subsequent model year heavy-duty diesel engine standards, pursuant to Section 1956.8(a)(2)(A) of Title 13 of the California Code of Regulations, shall either:
i. 
Be equipped with a verified Level 3 in-use strategy for particulate matter control (see title 13, CCR, sections 2700 to 2710), or
ii. 
Have its exhaust routed directly into the vehicle's exhaust pipe, upstream of the diesel particulate matter after treatment device.
(B) 
With advance approval of the Executive Officer of the California Air Resource Board, a certifying/verifying APS manufacturer may petition for an alternate compliance strategy other than described in (1)(A)(i) or (ii) in this subsection above. However, this provision is limited to manufacturers that can demonstrate, to the satisfaction of the Executive Officer of the California Air Resources Board, that their alternative strategy is equivalent (or "cleaner"), from an emissions standpoint, compared to the requirement described in (1)(A)(i) or (ii) in this subsection above. As an example, strategies that can use the available electric power infrastructure, instead of solely operating a diesel-fueled APS for engine and/or cab heating and cooling, may be able to use such a strategy to demonstrate compliance with these requirements.
(2) 
Fuel-Fired Heaters. Fuel-fired heaters must comply with the applicable California emission standards and test procedures as specified in the Low Emission Vehicle program requirements found in Title 13, California Code of Regulations, subsections 1961(a)(15) and (d), or in Part I.E.1.13 of the "California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles," as incorporated by reference in Title 13, California Code of Regulations, section 1961(d). However, the specified requirement that limits fuel-fired heaters from being operated above 40 degrees F does not apply.
(3) 
Other Idle Reduction Technologies. Other technologies that will reduce idling emissions may also be used, including the use of batteries, fuel cells, power inverter/chargers for on-shore electrical power, on-shore electric power infrastructure also known as truck stop electrification, and other technologies that produce minimal or no emissions. With the exception of battery and fuel cell powered APSs, power inverter/chargers, and electric power infrastructure, the use of other technologies are subject to advance Executive Officer approval and must be at least as effective in reducing idling emissions as the technologies described in subsections (c)(1), above, or the NOx idling emission standard specified in Title 13, California Code of Regulations, section 1956.8(a)(6)(C). The Executive Officer shall use good engineering judgment and test data to determine if an idle reduction technology provides idling emission controls equivalent to the standards specified in subsection (c)(A) above, or in Title 13, Section 1956.8(a)(6)(C) of the California Code of Regulations.
(4) 
Labeling Requirements. 2007 and subsequent model year commercial diesel vehicles equipped with an internal combustion APS meeting the requirements specified in subsection (c)(1) shall have a label affixed to the hood of the vehicle to allow operation of the APS in California. The labels shall meet the requirements specified in section 35.B.4 of the "California Exhaust Emission Standards and Test Procedures for 2004 and Subsequent Model Heavy-Duty Diesel Engines and Vehicles," as incorporated by reference in Title 13, Section 1956.8(b) of the California Code of Regulations.
(Added by Ord. No. 3486, effective 12-17-15)
(a) 
Except when a vehicle is located within 100 feet of a restricted area, subsection (a)(1) of Section 3-04-1020 does not apply, if the vehicle is equipped with:
(1) 
A primary diesel engine meeting the optional NOx idling emission standard pursuant to Title 13, California Code of Regulations, section 1956.8(a)(6)(C); and
(2) 
A label meeting the requirements pursuant to section 35.B.4 of the "California Exhaust Emission Standards and Test Procedures for 2004 and Subsequent Model Heavy-Duty Diesel Engines and Vehicles," as incorporated by reference in Title 13, California Code of Regulations, section 1956.8(b).

Idling of the primary diesel engine, operating a diesel-fueled APS, or operating other devices is mandatory for testing, servicing, repairing, or diagnostic purposes, including regeneration or maintenance of the exhaust emission control device during engine idling when the dash-board indicator light, if so equipped, is illuminated indicating that regeneration or maintenance is in progress;
(8) 
Idling when positioning or providing a power source for equipment or operations, other than transporting passengers or propulsion, which involve a power take off or equivalent mechanism and is powered by the primary engine for:
(A) 
Controlling cargo temperature, operating a lift, crane, pump, drill, hoist, mixer (such as a ready mix concrete truck), or other auxiliary equipment;
(B) 
Providing mechanical extension to perform work functions for which the vehicle was designed and where substitute alternate means to idling are not reasonably available; or
