Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Applicability. The requirements of this section are applicable to all small
				  off-road engines produced in the 2000 and later model years. Engines certified
				  to the voluntary standards in subsection
				  2403(b)(2)
				  are not eligible for participation in this program. Participation in the
				  averaging, banking and trading program is voluntary, but if a manufacturer
				  elects to participate, it must do so in compliance with the regulations set
				  forth in this section. The provisions of this section are limited to
				  HC+NOx (or NMHC+NOx, as
				  applicable), CO, and Particulate Matter emissions.
(b) General provisions.
(1) The certification averaging, banking, and
				  trading provisions for HC+NOx, CO, and Particulate
				  Matter emissions from eligible engines are described in this section.
(2) An engine family may use the averaging,
				  banking and trading provisions for HC+NOx,
				  NMHC+NOx, CO, and Particulate Matter emissions if it is
				  subject to regulation under this article with certain exceptions specified in
				  paragraph (3) of this section.
(3)
				  A manufacturer must not include in its calculation of credit generation and may
				  exclude from its calculation of credit usage, any new engines that are exported
				  from California, or that are not destined for California, unless the
				  manufacturer has reason or should have reason to believe that such engines have
				  been or will be imported in a piece of equipment.
(4) For an engine family using 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.
(5) A manufacturer may certify engine
				  families at Family Emission Limits (FELs) above or below the applicable
				  emission standard subject to the limitation in paragraph (6) of this section,
				  provided the summation of the manufacturer's projected balance of credits from
				  all credit transactions in a given model year is greater than or equal to zero,
				  as determined under paragraph (f).
(A) A
				  manufacturer of an engine family with an FEL exceeding the applicable emission
				  standard must obtain positive emission credits sufficient to address the
				  associated credit shortfall via averaging, banking, or trading.
(B) An engine family with an FEL below the
				  applicable emission standard may generate positive emission credits for
				  averaging, banking, or trading, or a combination thereof.
(C) In the case of a production line test
				  failure, credits may be used to cover subsequent production of engines for the
				  family in question if the manufacturer elects to recertify to a higher FEL.
				  Credits may be used to remedy a nonconformity determined by production line
				  testing or new engine compliance testing, at the discretion of the Executive
				  Officer.
(D) In the case of a
				  production line testing failure pursuant to section
				  2407,
				  a manufacturer may revise the FEL based upon production line testing results
				  obtained under section
				  2407
				  and upon Executive Officer approval. The manufacturer may use certification
				  credits to cover both past production and subsequent production as
				  needed.
(6) No engine
				  family may have an FEL that is greater than the emission levels in the table
				  below.

(7) Manufacturers must demonstrate compliance
				  under the averaging, banking, and trading provisions for a particular model
				  year by 270 days after the end of the model year. An engine family generating
				  negative credits for which the manufacturer does not obtain or generate an
				  adequate number of positive credits by that date from the same or previous
				  model year engines will violate the conditions of the Executive Order. The
				  Executive Order may be voided
ab initio
for this engine
				  family.
