1. Subparagraph (a). [No change.]

2. Amend subparagraph (b) as follows: Fuels meeting alternative 

specifications. We may allow you to use a different test fuel if you show us and 

we find that using it does not affect your ability to comply with all applicable 

emission standards using commercially available fuels.

3. Subparagraph (c). [No change.]

4. Amend subparagraph (d) as follows: Fuel specifications. The fuel 

parameters specified in this subpart depend on measurement procedures that 

are incorporated by reference.

3. Identification of New Clean Fuels to be Used in Certification Testing. 
As Amended: March 22, 2012

Date of Hearing: January 26-27, 2012

17

Any person may petition the state board to establish by regulation certification 

testing specifications for a new clean fuel for which specifications for the new 

clean fuel are not specifically set forth in paragraph §86.1313-98 as amended 

herein. Prior to adopting such specifications, the state board shall consider the 

relative cost-effectiveness of use of the fuel in reducing emissions compared to 

the 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 NMHC, NOx, and CO, and the potential risk 

associated with toxic air contaminants, as determined pursuant to 

the procedures set forth in the “California Test Procedures for 

Evaluating Substitute Fuels and New Clean Fuels through 2014,”

as adopted September 17, 1993 amended [INSERT DATE OF 

AMENDMENT] or the “California Test Procedures for Evaluating 

Substitute Fuels and New Clean Fuels in 2015 and Subsequent 

Years,” as adopted [INSERT DATE OF ADOPTION], as applicable. 

In the case of fuel-flexible vehicles or dual-fuel vehicles that were 

not certified on the new clean fuel but are capable of being 

operated on it, exhaust and evaporative emissions from the use of 

the new clean fuel shall not increase compared to exhaust and 

evaporative emissions from the use of gasoline that complies with 

Title 13, Division 3, Chapter 5, Article 1, California Code of 

Regulations.

(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.
