In addition, the APS or idle reduction technology used or operated on such a vehicle is exempt from the requirements specified in subsection (c)(3), below

(c)(3)Idle Reduction Technology Compliance Requirements. As an alternative to idling the primary engine, diesel-fueled engines/vehicles may, as an option, be equipped with alternative technologies, as listed and defined below in subsections (c)(3) (A), (c)(3)(B), and (c)(3)(C). If so equipped, these technologies are subject to the following requirements:

(c)(3)(A)Internal Combustion APS.

(c)(3)(A)1.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, CCR, shall either,

(c)(3)(A)1.a.be equipped with a verified Level 3 in-use strategy for particulate matter control (see title 13, CCR, sections 2700 to 2710), or

(c)(3)(A)1.b.have its exhaust routed directly into the vehicle's exhaust pipe, upstream of the diesel particulate matter aftertreatment device, or

(c)(3)(A)1.c.be certified to the 0.02 g/kW-hr PM emission standard specified in title 23, CCR, section 2423(n) and must comply with the requirements of title 13, CCR, sections 2420 to 2427.

(c)(3)(A)2.With advance Executive Officer approval, a certifying/verifying APS manufacturer may petition for an alternate compliance strategy other than described in (A)1. a. or b. in this subsection above. However, this provision is limited to manufacturers that can demonstrate, to the satisfaction of the Executive Officer, that their alternative strategy is equivalent (or “cleaner”), from an emissions standpoint, compared to the requirement described in (A)1.a. or b. 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.

(c)(3)(B)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, CCR, subsections 1961(a)(15) and (d), or in Part I.E.1.13 of the “California 2001 through 2014 Model Criteria Pollutant Exhaust Emission Standards and Test Procedures and 2009 through 2016 Model Greenhouse Gas Exhaust Emission Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles,” as incorporated by reference in title 13, CCR, section 1961(d). However, the specified requirement that limits fuel-fired heaters from being operated above 40°F does not apply.

(c)(3)(C)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 is subject to advance Executive Officer approval and must be at least as effective in reducing idling emissions as the technologies described in subsections (c)(3)(A), above, or the NOx idling emission standard specified in title 13, CCR, 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)(3)(A) above, or in title 13, CCR, section 1956.8(a)(6) (C).

(c)(3)(D)Labeling Requirements. 2007 and subsequent model year commercial diesel vehicles equipped with an internal combustion APS meeting the requirements specified in subsection (c)(3)(A) 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, CCR, section 1956.8(b).

(d)Exceptions.

(d)(1)Except when a vehicle is located within 100 feet of a restricted area, subsections (c)(1)(A)1 and (c)(1)(B)1 do not apply, if the vehicle is equipped with

(d)(1)(A)a primary diesel engine meeting the optional NOx idling emission standard pursuant to title 13, CCR, section 1956.8(a)(6) (C); and

(d)(1)(B)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, CCR, section 1956.8(b).

(d)(2)Subsection (c)(1) does not apply for the period or periods during which

(d)(2)(A)a bus is idling for

(d)(2)(A)1.up to 10.0 minutes prior to passenger boarding, or

(d)(2)(A)2.when passengers are onboard;

(d)(2)(B)prior to January 1, 2008, idling of the primary diesel-engine is necessary to power a heater, air conditioner, or any ancillary equipment during sleeping or resting in a sleeper berth. This provision does not apply when operating within 100 feet of a restricted area;

(d)(2)(C)idling when the vehicle must remain motionless due to traffic conditions, an official traffic control device, or an official traffic control signal over which the driver has no control, or at the direction of a peace officer, or operating a diesel- fueled APS or other device at the direction of a peace officer;

(d)(2)(D)idling when the vehicle is queuing that at all times is beyond 100 feet from any restricted area;

(d)(2)(E)idling of the primary diesel engine, operating a diesel-fueled APS, or operating other devices when forced to remain motionless due to immediate adverse weather conditions affecting the safe operation of the vehicle or due to mechanical difficulties over which the driver has no control;

(d)(2)(F)idling to verify that the vehicle is in safe operating condition as required by law and that all equipment is in good working order, either as part of a daily vehicle inspection or as otherwise needed, provided that such engine idling is mandatory for such verification;

(d)(2)(G)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 dashboard indicator light, if so equipped, is illuminated indicating that regeneration or maintenance is in progress;

(d)(2)(H)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 diesel engine for:

(d)(2)(H)1.controlling cargo temperature, operating a lift, crane, pump, drill, hoist, mixer (such as a ready mix concrete truck), or other auxiliary equipment;

(d)(2)(H)2.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

(d)(2)(H)3.collection of solid waste or recyclable material by an entity authorized by contract, license, or permit by a school or local government;

(d)(2)(I)idling of the primary diesel engine, operating a diesel-fueled APS, or operating other devices when operating defrosters, heaters, air conditioners, or other equipment solely to prevent a safety or health emergency;

(d)(2)(J)idling of the primary diesel engine, operating a diesel-fueled APS, or operating other devices by authorized emergency vehicles while in the course of providing services for which the vehicle is designed;

(d)(2)(K)idling of military tactical vehicles during periods of training, testing, and deployment;

(d)(2)(L)idling when operating equipment such as a wheelchair or people assist lift as prescribed by the Americans with Disabilities Act;

(d)(2)(M)idling of armored cars in the course of providing services for which the vehicle is designed; and
