Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Applicability. The requirements of this section 2408.2 are applicable to all
				  zero-emission generators as defined in section
				  2401
				  produced in the 2022 through 2026 model years. Participation in this program is
				  voluntary, but if a manufacturer elects to participate, it must do so in
				  compliance with the provisions set forth in this section 2408.2. The provisions
				  of this section 2408.2 are limited to HC+NOx (or
				  NMHC+NOx, as applicable) emissions.
(b) General provisions.
(1) Zero-emission generator credits may be
				  used to offset emissions for any engine family comprised of generator
				  engines.
(2) A manufacturer must
				  only include in its calculation of zero-emission generator credit generation
				  zero-emission generators that are sold and used in California.
(3) For an engine family using zero-emission
				  generator credits to compensate for negative certification emission credits, a
				  manufacturer may, at its option, include its entire production of that engine
				  family in its calculation of credit usage for a given model year.
(4) A manufacturer of zero-emission
				  generators that wishes to generate zero-emission generator credits must certify
				  zero-emission generators at a family emission limit (FEL) of zero grams per
				  kilowatt-hour.
(A) A manufacturer of
				  zero-emission generators that certifies an engine family as a zero-emission
				  generator engine family may generate positive zero-emission generator credits
				  for averaging, banking, or trading, or a combination thereof.
(B) Except as noted in section
				  2408.2(b)(4)(C), an engine family certified as a zero-emission generator engine
				  family must meet the durability requirements listed in Table 1 of this section
				  2408.2.

(C) A small off-road equipment family that is
				  certified as a zero-emission generator family, but cannot achieve the full
				  durability period, may generate 75 percent of the zero-emission generator
				  credits if the zero-emission generator can meet a minimum of 75 percent up to
				  99 percent of the durability period. The amount of zero-emission generator
				  credits would be calculated as 75 percent of the amount of credits designated
				  in Table 1 of this section.
(D)
				  Minimum requirements for zero-emission generators.
1. A small off-road equipment family must
				  meet all of the requirements of this subsection to be eligible for
				  certification as a zero-emission generator family.
a. A zero-emission generator must have a
				  device capable of providing 120-Volt nominal alternating current power as well
				  as at least one NEMA 5-15 receptacle.
b. A zero-emission generator shall contain a
				  zero-emission power generation device, an energy storage device, or any
				  combination of both of these devices.
c. A zero-emission generator must meet the
				  minimum specifications indicated in Table 1 of this section 2408.2.
2. Durability testing must be
				  performed in an equipment configuration that is representative of actual
				  operation of the equipment by the ultimate purchaser (e.g., using standard
				  battery package cycling, non-azimuth tracking solar array, commercially
				  available hydrogen (H2) fuel sources).
3. The minimum durability period is based on
				  the use cycle for a corresponding generator engine duty cycle tested with an
				  electrical load bank using a five-mode duty cycle (with no idle mode) as
				  described in Appendix II to the "California Exhaust Emission Standards and Test
				  Procedures for New 2013 and Later Small Off-Road Engines; Engine-Testing
				  Procedures (Part 1054)," adopted October 25, 2012, and amended January 1, 2023.
				  An electrical load bank shall be used to apply a load to the zero-emission
				  generator for testing to demonstrate compliance with the requirements of this
				  section.
(E) In order to
				  generate zero-emission generator credits, manufacturers of zero-emission
				  generators must provide the ultimate purchaser with all equipment and
				  accessories necessary to meet the requirements set forth in Table 1 of this
				  section 2408.2, including any energy storage devices such as batteries. For
				  zero-emission generators that use fuel such as compressed
				  H2, the fuel is not required to be provided as part of
				  the package provided to an ultimate purchaser.
(F) A manufacturer of zero-emission
				  generators must include in the certification application, a description of the
				  operational sequence over one deployment of the zero-emission generator. The
				  operational sequence should include, as applicable, the discharge profile,
				  power production profile, and the storage profile of any available
				  storage.
(G) Manufacturers must
				  demonstrate compliance under the averaging, banking, and trading provisions of
				  this section 2408.2 for a particular model year within 270 days after the end
				  of the model year.
