"(iv) preparing generally applicable regulations, or
"(v) modeling, analyses, and demonstrations, and
"(vi) preparing inventories and tracking emissions.
"(B) The total amount of fees collected by the permitting
authority shall conform to the following requirements:
"(i) The Administrator shall not approve a program as
meeting the requirements of this paragraph unless the State
demonstrates that, except as otherwise provided in
subparagraphs (ii) through (v) of this subparagraph, the
program will result in the collection, in the aggregate, from
all sources subject to subparagraph (A), of an amount not less
than $25 per ton of each regulated pollutant, or such other
amount as the Administrator may determine adequately reflects
the reasonable costs of the permit program.
"(ii) As used in this subparagraph, the term `regulated
pollutant' shall mean (I) a volatile organic compound; (II)
each pollutant regulated under section 111 or 112; and (III)
each pollutant for which a national primary ambient air quality
standard has been promulgated (except that carbon monoxide
shall be excluded from this reference).
"(iii) In determining the amount under clause (i), the
permitting authority is not required to include any amount of
regulated pollutant emitted by any source in excess of 4,000
tons per year of that regulated pollutant.
"(iv) The requirements of clause (i) shall not apply if the
permitting authority demonstrates that collecting an amount
less than the amount specified under clause (i) will meet the
requirements of subparagraph (A).
"(v) The fee calculated under clause (i) shall be increased
(consistent with the need to cover the reasonable costs
authorized by subparagraph (A)) in each year beginning after
the year of the enactment of the Clean Air Act Amendments of
1990 by the percentage, if any, by which the Consumer Price
Index for the most recent calendar year ending before the
beginning of such year exceeds the Consumer Price Index for the
calendar year 1989. For purposes of this clause-
"(I) the Consumer Price Index for any calendar year is
the average of the Consumer Price Index for all-urban
consumers published by the Department of Labor, as of the
close of the 12-month period ending on August 31 of each
calendar year, and
"(II) the revision of the Consumer Price Index which is
most consistent with the Consumer Price Index for calendar
year 1989 shall be used.
"(C)(i) If the Administrator determines, under subsection (d),
that the fee provisions of the operating permit program do not
meet the requirements of this paragraph, or if the Administrator
makes a determination, under subsection (i), that the permitting
authority is not adequately administering or enforcing an
approved fee program, the Administrator may, in addition to
taking any other action authorized under this title, collect
reasonable fees from the sources identified under subparagraph
(A). Such fees shall be designed solely to cover the
Administrator's costs of administering the provisions of the
permit program promulgated by the Administrator.
