        (F) Except as provided in subparagraph (G), the maximum heat 
    loss of unfired hot water storage tanks shall be 6.5 Btu per hour 
    per square foot of tank surface area.
        (G) Storage water heaters and hot water storage tanks having 
    more than 140 gallons of storage capacity need not meet the standby 
    loss or heat loss requirements specified in subparagraphs (A) 
    through (C) and subparagraphs (E) and (F) if the tank surface area 
    is thermally insulated to R-12.5 and if a standing pilot light is 
    not used.

    (6)(A) If ASHRAE/IES Standard 90.1, as in effect on October 24, 
1992, is amended with respect to any small commercial package air 
conditioning and heating equipment, large commercial package air 
conditioning and heating equipment, packaged terminal air conditioners, 
packaged terminal heat pumps, warm-air furnaces, packaged boilers, 
storage water heaters, instantaneous water heaters, or unfired hot water 
storage tanks, the Secretary shall establish an amended uniform national 
standard for that product at the minimum level for each effective date 
specified in the amended ASHRAE/IES Standard 90.1, unless the Secretary 
determines, by rule published in the Federal Register and supported by 
clear and convincing evidence, that adoption of a uniform national 
standard more stringent than such amended ASHRAE/IES Standard 90.1 for 
such product would result in significant additional conservation of 
energy and is technologically feasible and economically justified.
    (B)(i) If the Secretary issues a rule containing such a 
determination, the rule shall establish such amended standard. In 
determining whether a standard is economically justified for the 
purposes of subparagraph (A), the Secretary shall, after receiving views 
and comments furnished with respect to the proposed standard, determine 
whether the benefits of the standard exceed its burdens by, to the 
greatest extent practicable, considering--
        (I) the economic impact of the standard on the manufacturers and 
    on the consumers of the products subject to such standard;
        (II) the savings in operating costs throughout the estimated 
    average life of the product in the type (or class) compared to any 
    increase in the price of, or in the initial charges for, or 
    maintenance expenses of, the products which are likely to result 
    from the imposition of the standard;
        (III) the total projected amount of energy savings likely to 
    result directly from the imposition of the standard;
        (IV) any lessening of the utility or the performance of the 
    products likely to result from the imposition of the standard;
        (V) the impact of any lessening of competition, as determined in 
    writing by the Attorney General, that is likely to result from the 
    imposition of the standard;
        (VI) the need for national energy conservation; and
        (VII) other factors the Secretary considers relevant.

    (ii) The Secretary may not prescribe any amended standard under this 
paragraph which increases the maximum allowable energy use, or decreases 
the minimum required energy efficiency, of a covered product. The 
Secretary may not prescribe an amended standard under this subparagraph 
if the Secretary finds (and publishes such finding) that interested 
persons have established by a preponderance of the evidence that a 
standard is likely to result in the unavailability in the United States 
in any product type (or class) of performance characteristics (including 
reliability), features, sizes, capacities, and volumes that are 
substantially the same as those generally available in the United States 
at the time of the Secretary's finding. The failure of some types (or 
classes) to meet this criterion shall not affect the Secretary's 
determination of whether to prescribe a standard for other types or 
classes.
    (C) A standard amended by the Secretary under this paragraph shall 
become effective for products manufactured--
        (i) with respect to small commercial package air conditioning 
    and heating equipment, packaged terminal air conditioners, packaged 
    terminal heat pumps, warm-air furnaces, packaged boilers, storage 
    water heaters, instantaneous water heaters, and unfired hot water 
    storage tanks, on or after a date which is two years after the 
    effective date of the applicable minimum energy efficiency 
    requirement in the amended ASHRAE/IES standard referred to in 
    subparagraph (A); and
        (ii) with respect to large commercial package air conditioning 
    and heating equipment, on or after a date which is three years after 
    the effective date of the applicable minimum energy efficiency 
    requirement in the amended ASHRAE/IES standard referred to in 
    subparagraph (A);

except that an energy conservation standard amended by the Secretary 
pursuant to a rule under subparagraph (B) shall become effective for 
products manufactured on or after a date which is four years after the 
date such rule is published in the Federal Register.

(b) Electric motors

    (1) Except for definite purpose motors, special purpose motors, and 
those motors exempted by the Secretary under paragraph (2), each 
electric motor manufactured (alone or as a component of another piece of 
equipment) after the 60-month period beginning on October 24, 1992, or 
in the case of an electric motor which requires listing or certification 
by a nationally recognized safety testing laboratory, after the 84-month 
period beginning on October 24, 1992, shall have a nominal full load 
efficiency of not less than the following:

    (2)(A) The Secretary may, by rule, provide that the standards 
specified in paragraph (1) shall not apply to certain types or classes 
of electric motors if--
        (i) compliance with such standards would not result in 
    significant energy savings because such motors cannot be used in 
    most general purpose applications or are very unlikely to be used in 
    most general purpose applications; and
        (ii) standards for such motors would not be technologically 
    feasible or economically justified.

    (B) Not later than one year after October 24, 1992, a manufacturer 
seeking an exemption under this paragraph with respect to a type or 
class of electric motor developed on or before October 24, 1992, shall 
submit a petition to the Secretary requesting such exemption. Such 
petition shall include evidence that the type or class of motor meets 
the criteria for exemption specified in subparagraph (A).
    (C) Not later than two years after October 24, 1992, the Secretary 
shall rule on each petition for exemption submitted pursuant to 
subparagraph (B). In making such ruling, the Secretary shall afford an 
opportunity for public comment.
    (D) Manufacturers of types or classes of motors developed after 
October 24, 1992, to which standards under paragraph (1) would be 
applicable may petition the Secretary for exemptions from compliance 
with such standards based on the criteria specified in subparagraph (A).
    (3)(A) The Secretary shall publish a final rule no later than the 
end of the 24-month period beginning on the effective date of the 
standards established under paragraph (1) to determine if such standards 
should be amended. Such rule shall provide that any amendment shall 
apply to electric motors manufactured on or after a date which is five 
years after the effective date of the standards established under 
paragraph (1).
    (B) The Secretary shall publish a final rule no later than 24 months 
after the effective date of the previous final rule to determine whether 
to amend the standards in effect for such product. Any such amendment 
shall apply to electric motors manufactured after a date which is five 
years after--
        (i) the effective date of the previous amendment; or
        (ii) if the previous final rule did not amend the standards, the 
    earliest date by which a previous amendment could have been 
    effective.
