                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 79--REGISTRATION OF FUELS AND FUEL ADDITIVES--Table of Contents
 
            Subpart F--Testing Requirements for Registration
 
Sec. 79.58  Special provisions.

    (a) Relabeled Additives. Sellers of relabeled additives (pursuant to 
Sec. 79.50) are not required to comply with the provisions of 
Sec. 79.52, 79.53 or 79.59, except that such sellers are required to 
comply with Sec. 79.59(b).
    (b) Low Vapor Pressure Fuels and Additives. Fuels which are not 
designated as ``evaporative fuels'' and fuel additives which are not 
designated as ``evaporative fuel additives'' pursuant to the definitions 
in Sec. 79.50 need not undergo the emission characterization or health 
effects testing specified in Secs. 79.52 and 79.53 for evaporative 
emissions. At EPA's discretion, the evaporative emissions of such fuels 
and additives may be required to undergo Tier 3 testing, pursuant to 
Sec. 79.54.
    (c) Alternative Tier 2 Provisions. At EPA's discretion, EPA may 
modify the standard Tier 2 health effects testing requirements for a 
fuel or fuel additive (or group). Such modification may encompass 
substitution, addition, or deletion of Tier 2 studies or study 
specifications, and/or changes in underlying engine or equipment 
requirements, except that a Tier 2 endpoint will not be deleted in the 
absence of existing information deemed adequate by EPA or alternative 
testing requirements for such endpoint. If warranted by the particular 
requirements, EPA will allow additional time for completion of the 
alternative Tier 2 testing program.
    (1) When EPA intends to require testing in lieu of or in addition to 
standard Tier 2 health testing, EPA will notify the responsible 
manufacturer (or group) by certified letter of the specific tests which 
EPA is proposing to require in lieu of or in addition to Tier 2, and the 
proposed schedule for completion and submission of such tests. A copy of 
the letter will be placed in the public record. EPA intends to send the 
notification prior to November 27, 1995, or in the case of new fuels and 
additives (as defined in Sec. 79.51(c)(3)), within 18 months of EPA's 
receipt of an intent to register such product. However, EPA's 
notification to the manufacturer (or group) may occur at any time up to 
EPA's receipt of Tier 2 data for the product(s) in question. EPA will 
provide the manufacturer with 60 days from the date of receipt of the 
notice to comment on the tests which EPA is proposing to require and on 
the proposed schedule. If the manufacturer believes that undue costs or 
hardships will occur as a result of EPA's delay in providing 
notification of alternative Tier 2 requirements, then the manufacturer's 
comments should describe and include evidence of such hardship. In 
particular, if the standard Tier 2 toxicology testing for the fuel or 
additive in question has already begun at the time the manufacturer 
receives EPA's notification of proposed alternative Tier 2 requirements, 
then EPA shall refrain from requiring alternative Tier 2 tests provided 
that EPA receives the

[[Page 527]]

standard Tier 2 data and report (pursuant to Sec. 79.59(c)) within one 
year of the date on which the toxicology testing began.
    (2) EPA will issue a notice in the Federal Register announcing its 
intent to require special testing in lieu of or in addition to the 
standard Tier 2 testing for a particular fuel or additive manufacturer 
or group, and that a copy of the letter to the manufacturer or group 
describing the proposed alternative Tier 2 testing for that manufacturer 
or group is available in the public record for review and comment. The 
public shall have a minimum of 30 days after the publication of this 
notice to comment on the proposed alternative Tier 2 testing.
    (3) EPA will include in the public record a copy of any timely 
comments concerning the proposed alternative Tier 2 testing requirements 
received from the affected manufacturer or group or from the public, and 
the responses of EPA to such comments. After reviewing all such comments 
received, EPA may adopt final alternative Tier 2 requirements by sending 
a certified letter describing such final requirements to the 
manufacturer or group. In that event, EPA will also issue a notice in 
the Federal Register announcing that it has adopted final alternative 
Tier 2 requirements and that a copy of the letter adopting the 
requirements has been included in the public record.
    (4) After EPA's receipt of a manufacturer's (or group's) submittals, 
EPA will notify the responsible manufacturer (or group) regarding the 
adequacy of the submittal and potential Tier 3 testing requirements 
according to the same relative time intervals and by the same procedures 
as specified in Sec. 79.51 (c) and (d) for routine Tier 1 and Tier 2 
submittals.
    (d) Small Business Provisions. (1) For purposes of these provisions, 
when subsidiary, divisional, or other complex business arrangements 
exist, manufacturer is defined as the business entity with ultimate 
ownership of all related parents, subsidiaries, divisions, branches, or 
other operating units. Total annual sales means the average of the 
manufacturer's total sales revenue, excluding any revenue which 
represents the collection of Federal, State, or local excise taxes or 
sales taxes, in each of the three years prior to such manufacturer's 
submittal to EPA of the basic registration information pursuant to 
Sec. 79.59(b)(2) through (b)(5).
    (2) Provisions Applicable to Baseline and Non-baseline Products. A 
manufacturer with total annual sales less than $50 million is not 
required to meet the requirements of Tier 1 and Tier 2 (specified in 
Secs. 79.52 and 79.53) with regard to such manufacturer's fuel and/or 
additive products which meet the criteria for inclusion in a Baseline or 
Non-baseline group pursuant to Sec. 79.56. Upon such manufacturer's 
satisfactory completion and submittal to EPA of basic registration data 
specified in Sec. 79.59(b), the manufacturer may request and EPA shall 
issue a registration for such product, subject to Sec. 79.51(c) and 
paragraphs (d)(4) and (d)(5) of this section.
    (3) Provisions Applicable to Atypical Products. A manufacturer with 
total annual sales less than $10 million is not required to meet the 
requirements of Tier 2 (specified in Sec. 79.53) in regard to such 
manufacturer's fuel and/or additive products which meet the criteria for 
inclusion in an Atypical group pursuant to Sec. 79.56. Upon such 
manufacturer's satisfactory completion and submittal to EPA of basic 
registration data specified in Sec. 79.59(b) and Tier 1 information 
specified in Sec. 79.52 for an Atypical fuel or additive, the 
manufacturer may request and EPA shall issue a registration for such 
product, subject to Sec. 79.51(c) and paragraphs (d)(4) and (d)(5) of 
this section. Compliance with Tier 1 requirements under this paragraph 
may be accomplished by the individual manufacturer or as a part of a 
group pursuant to Sec. 79.56.
    (4) Any registration granted by EPA under the provisions of this 
section are conditional upon satisfactory completion of any Tier 3 
requirements which EPA may subsequently impose pursuant to Sec. 79.54. 
In such circumstances, the Tier 3 requirements might include (but would 
not necessarily be limited to) information which would otherwise have 
been required under the provisions of Tier 1 and/or Tier 2.
    (5) The provisions in paragraphs (d)(2) and (d)(3) of this section 
are voluntary

[[Page 528]]

on the part of qualifying small manufacturers. Such manufacturers may 
choose to fulfill the standard requirements for their fuels and 
additives, individually or as a part of a group, rather than satisfying 
only the requirements specified in paragraphs (d)(2) and/or (d)(3) of 
this section. If a qualifying small manufacturer elects these special 
provisions rather than the standard requirements for a product, then EPA 
will generally assume that any additional information submitted by other 
manufacturers, for fuels and additives meeting the same grouping 
criteria (under Sec. 79.56) as that of the small manufacturer's product, 
is pertinent to further testing and/or regulatory decisions that may 
affect the small manufacturer's product.
    (6) In the case of an additive for which the manufacturer is not 
required to meet the requirements of Tier 2 pursuant to paragraph (d)(3) 
of this section:
    (i) A fuel manufacturer which blends such an additive into fuel 
shall not be required to meet the requirements of Tier 2 with respect to 
such additive/fuel mixture.
    (ii) An additive manufacturer which blends such an additive with one 
or more other registered additive products and/or with substances 
containing only carbon and/or hydrogen shall not be required to meet the 
requirements of Tier 2 with respect to such additive or additive blend.
    (e) Aftermarket Aerosol Additives. (1) To obtain registration for an 
aftermarket aerosol fuel additive, the manufacturer shall provide 
existing information in the form of a literature search, a discussion of 
the potential exposure(s) to such product, and the basic registration 
data specified in Sec. 79.59(b).
    (2) The literature search shall include existing data on potential 
health and welfare effects due to exposure to the aerosol product itself 
and its raw (uncombusted) components. The analysis for potential 
exposures shall be based on the actual or anticipated production volume 
and market distribution of the particular aerosol product, and its 
estimated frequency of use. Other Tier 1 and Tier 2 requirements are not 
routinely required for aerosol products. EPA will review the submitted 
information and, at EPA's discretion, may require from the manufacturer 
further information and/or testing under Tier 3 on a case-by-case basis.
