4. Section numbering; construction.

§86.084-4. September 21, 1994. [No change.]

The section numbering convention employed in these test procedures, in order of

priority, is I.1.A.1.1. in order to distinguish California procedures and requirements from

those of the U.S. EPA. References in these test procedures to specific sections of the

Code of Federal Regulations maintain the same numbering system employed in the Code

of Federal Regulations. California-only requirements are set forth in a separate

subsection. In the beginning of each section the generic notation §86.xxx-1 is used when

there is more than one applicable section (or when no versions of the section are being

incorporated) to indicate the section being discussed without regard to model year. The

years of applicability (denoted generically by “xxx”) are added as applicable in the pertinent

subsections.

In cases where the entire CFR section is incorporated by reference with no

modifications, the notation “[No change.]” is used. In cases where the federal requirements

are modified by California requirements, the notation “Amend (or delete) subparagraph

(__) as follows:” is used. If the federal requirement is not applicable, the notation “[n/a]” is

used. In cases where there are California only requirements, the additional California

requirements are noted in a separate subsection with the numbering convention set forth

above.

If a CFR section for a specific model year is set forth in this document, and that CFR

section references previous CFR sections, then all previously referenced CFR sections are

deemed incorporated into this document unless otherwise noted.

use of other fuels. Whenever the state board adopts specifications for a new clean

fuel for certification testing, it shall also establish by regulation specifications for the

fuel as it is sold commercially to the public.

(a) If the proposed new clean fuel may be used to fuel existing motor

vehicles, the state board shall not establish certification specifications for the fuel

unless the petitioner has demonstrated that:

(1) Use of the new clean fuel in such existing motor vehicles would

not increase emissions of NMOG (on a reactivity-adjusted basis), NOx, CO, and the

potential risk associated with toxic air contaminants, as determined pursuant to the

procedures set forth in "California Test Procedures for Evaluating Substitute Fuels

and New Clean Fuels," as adopted September 17, 1993. In the case of fuel-flexible

vehicles or dual-fuel vehicles which were not certified on the new clean fuel but are

capable of being operated on it, emissions during operation with the new clean fuel

shall not increase compared to emissions during vehicle operation on gasoline.

(2) Use of the new clean fuel in such existing motor vehicles would

not result in increased deterioration of the vehicle and would not void the warranties

of any such vehicles.

(b) Whenever the state board designates a new clean fuel pursuant to

this section, the state board shall also establish by regulation required

specifications for the new clean fuel sold commercially in California.

accordance with the "California Non-Methane Organic Gas Test Procedures" as

last amended July 30, 2002, which is incorporated by reference in section

1956.8(d), title 13, CCR.

Amend subparagraph (d) Meaning of symbols as follows:

(1)(ii) If gaseous fuels are being used, 18.64 g/ft3 for natural gas and 17.28 g/ft3 for

liquefied petroleum gas, assuming an average carbon to hydrogen ratio of 1:3.803

for natural gas and 1:2.656 for liquefied petroleum gas, at 68o F and 760 mm Hg

pressure. The Executive Officer may approve other density values deemed

appropriate by a manufacturer when gaseous fuels are being used.
