Registration of Fuels and Fuel Additives: Minor Changes to the 
Testing Requirements for Registration

AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.




[[Page 36507]]

SUMMARY: The Environmental Protection Agency (``EPA'' or the 
``Agency'') is issuing, as a direct final rule, minor changes to the 
health-effects testing requirements at 40 CFR Part 79, Subpart F. These 
requirements deal with the exposure of animals to evaporate and exhaust 
emissions from motor vehicles. The changes allow for increased 
flexibility in engine selection, correct an inconsistency with respect 
to mixing chamber quality assurance, establish clearer exposure timing 
requirements, provide a necessary option for the units in which 
emissions data are reported for heavy-duty vehicle engines, clarify 
oxygen purity requirements, make some minor syntax changes, clarify the 
handling of the measurements of background chemical species in the 
ambient air used by the engine generating emissions, clarify the 
driving schedules, clarify the exposure concentration requirements in 
the inhalation chamber, clarify dilution system requirements, and 
clarify the requirements for the collection of particulates and semivolatiles. 
These changes will reduce the testing costs without 
affecting the environmental objectives. This action is being taken 
without prior notice because EPA believes that the minor changes in the 
testing requirements will be noncontroversial.
    The rule implementing the testing requirements was finalized on May 
27, 1994 (59 FR 33042, June 27, 1994). The test data will be used by 
the Agency to determine if the emissions of certain gasolines and/or 
diesel fuels present an unacceptable risk to public health. For 
additional background information see the procedure in this issue of 
the Federal Register proposing changes to the registration regulations. 
The changes in this direct final rule have also been incorporated into 
that notice of proposed rulemaking. If an adverse comment or a request 
for a public hearing is received on this direct final rule, EPA will 
withdraw the direct final rule and address the comment(s) in a 
subsequent final rule based on the proposed rule.

DATES: This action will be effective on August 26, 1996 unless EPA 
receives an adverse comment or a request for a public hearing by August 
12, 1996. If EPA receives an adverse comment or hearing request by that 
date, EPA will withdraw this action via a document in the Federal 
Register. All correspondence should be directed to the addresses below.

ADDRESSES: Materials relevant to this rulemaking have been placed in 
Docket A-90-07. The docket is located at the U.S. Environmental 
Protection Agency, Air Docket Section (LE-131), 401 M Street, S.W., 
Washington, DC 20460 in Room M-1500 of Waterside Mall. Documents may be 
inspected between the hours of 8:00 a.m. and 5:30 p.m., Monday through 
Friday. A reasonable fee may be charged for copying. Those wishing to 
notify EPA of their intent to submit an adverse comment or request a 
public hearing should contact Joseph Fernandes (202) 233-9756 or Jim 
Caldwell (202) 233-9303 at the EPA.

FOR FURTHER INFORMATION CONTACT: Joseph Fernandes (202) 233-9756 or Jim 
Caldwell (202) 233-9303, USEPA, Office of Mobile Sources, Fuels and
