read as follows:4
640.220. 1. For the purpose of protecting the air, 1
water and land resources of the state, there is hereby 2
created in the state treasury a fund to be known as the 3

from air pollution permit fees, gifts, bequests, donations, 5
or any other moneys so designated shall be paid to the 6
director of the department of natural resources, transmitted 7
to the director of revenue and deposited in the state 8
treasury to the credit of an appropriate subaccount of the 9

purposes specified by law. The air pollution permit fee 11
revenues shall be deposited in an appropriate subaccount of 12
the natural resources protection fund and, subject to 13
appropriation by the general assembly, shall be used by the 14
department to carry out the general administration of 15
SS SB 1033 2
section 643.075. The water pollution permit fee revenues 16
generated through sections 644.052, 644.053, 644.054 and 17
644.061 shall be paid to the director of the department of 18
natural resources, transmitted to the director of the 19
department of revenue and deposited to the credit of the 20
water pollution permit fee subaccount of the natural 21
resources protection fund and, subject to appropriation by 22
the general assembly, shall be used by the department to 23
carry out the administration of sections 644.006 to 644.141. 24
2. Effective July 1, 1991, and before June 30, 2027, 25
the provisions of section 33.080 to the contrary 26

preceding biennium's collections shall revert to the general 29
revenue fund of the state at the end of each biennium. 30
Beginning July 1, 2027, any unexpended balance in the 31
subaccounts of the natural resources protection fund that 32
exceeds the preceding biennium's collections shall not 33
revert to the general revenue fund of the state at the end 34
of each biennium. All interest earned on the natural 35
resources protection funds shall accrue to appropriate 36
subaccounts. 37
3. Beginning July 1, 2027, and annually on July first 38
of each succeeding year, the commissioner of administration 39
shall use taxable sales reports to estimate the amount of 40
state general revenue sales and use tax derived from 41
electric power distribution (NAICS code 221122, or its 42
successor) in the immediately preceding calendar year and 43
shall report such amount to the state treasurer. The state 44
treasurer shall transfer five percent of such general 45
revenue sales and use taxes to the air pollution permit fees 46
subaccount of the natural resources protection fund and such 47

funds, subject to appropriation by the general assembly, 48
shall be used by the department solely for the purpose of 49
funding the air pollution control program. Any provision of 50
law to the contrary notwithstanding, amounts transferred in 51
accordance with this subsection shall not revert to the 52

643.355, all motor vehicles which are domiciled, registered 2
or primarily operated in an area for which the commission 3
has established a motor vehicle emissions inspection program 4
pursuant to sections 643.300 to 643.355 shall be inspected 5
and approved prior to sale or transfer; provided that, if 6
such vehicle is inspected and approved prior to sale or 7
transfer, such vehicle shall not be subject to another 8
emissions inspection for ninety days after the date of sale 9
or transfer of such vehicle. In addition, any such vehicle 10
manufactured as an even-numbered model year vehicle shall be 11
inspected and approved under the emissions inspection 12
program established pursuant to sections 643.300 to 643.355 13
in each even-numbered calendar year and any such vehicle 14
manufactured as an odd-numbered model year vehicle shall be 15

(a) With prior inspection and approval as provided in 101
subdivision (2) of this subsection; or 102

in subdivision (3) of this subsection. 104
(2) If the dealer chooses to sell the vehicle with 105
prior inspection and approval, the dealer shall disclose, in 106
writing, prior to sale, whether the vehicle obtained 107
approval by meeting the emissions standards established 108
pursuant to sections 643.300 to 643.355 or by obtaining a 109
waiver pursuant to section 643.335. A vehicle sold pursuant 110
to this subdivision by a licensed motor vehicle dealer shall 111
be inspected and approved within the one hundred twenty days 112
immediately preceding the date of sale, and, for the purpose 113
of registration of such vehicle, such inspection shall be 114
considered timely. 115
(3) If the dealer chooses to sell the vehicle without 116

vehicle within ten days of the date of purchase, provided 118
that the vehicle has no more than one thousand additional 119
SS SB 1033 7

and approved without the option for a waiver of the 123
emissions standard and return the vehicle to the purchaser 124
with a valid emissions certificate and sticker within five 125
working days or the purchaser and dealer may enter into any 126
other mutually acceptable agreement. If the dealer chooses 127
to sell the vehicle without prior inspection and approval, 128
the dealer shall disclose conspicuously on the sales 129
contract and bill of sale that the purchaser has the option 130
to return the vehicle within ten days, provided that the 131
vehicle has no more than one thousand additional miles since 132
the time of sale, to have the dealer repair the vehicle and 133
provide an emissions certificate and sticker within five 134
working days if the vehicle fails, upon inspection, to meet 135
the emissions standards established by the commission, or 136
enter into any mutually acceptable agreement with the 137
dealer. A violation of this subdivision shall be an 138
unlawful practice as defined in section 407.020. No 139
emissions inspection shall be required pursuant to sections 140

307.380. 144
643.350. 1. A fee, not to exceed twenty-four dollars, 1
may be charged for an emissions inspection conducted under 2
the emissions inspection program established pursuant to 3
sections 643.300 to 643.355. 4
2. The fee shall be conspicuously posted on the 5
premises of each emissions inspection station. 6
SS SB 1033 8
3. The commission shall establish, by rule, the 7
portion of the fee amount to be remitted by the emission 8
inspection station to the director of revenue and the number 9
of days allowed for remitting fees. 10
4. The official emission inspection station shall 11
remit the portion of fees collected, as established by the 12
commission pursuant to this section, to the state treasurer 13
within the time period established by the commission. The 14
state treasurer shall deposit the fees received in the state 15
treasury to the credit of the "Missouri Air Emission 16
Reduction Fund", which is hereby created. Moneys in the 17
fund shall, subject to appropriation, be expended for the 18
administration and enforcement of sections 643.300 to 19
643.355 by the department of natural resources, the Missouri 20
highway patrol, and other appropriate agencies. Any balance 21
in the fund at the end of the biennium shall remain in the 22
fund and shall not be subject to the provisions of section 23
33.080. All interest earned by moneys in the fund shall 24
accrue to the fund. [If in the immediate previous fiscal 25

two percent or more, the state treasurer may deposit moneys, 27
except for gifts, donations, or bequests, received under 28
this section beginning January first of the current fiscal 29
year into the state general revenue fund. Otherwise, the 30
state treasurer shall deposit such moneys in accordance with 31
the provisions of this section.] 32
5. In addition to funds from the Missouri air emission 33
reduction fund, costs of capital or operations may be 34
supplemented, upon appropriation, from the general revenue 35
fund, the state highway department fund, federal funds or 36
other funds available for that purpose. 37
SS SB 1033 9
643.675. 1. For purposes of this section, the 1
following terms mean: 2
(1) "Air dispersion modeling", the process of 3
simulating particle matter dispersion from an emission point 4
to help predict downwind concentrations to ensure compliance 5
with air quality standards, considering factors like wind, 6
terrain, and building effects, in order to assess health 7
impacts and manage pollution; 8
(2) "Cotton gin", a machine that separates cotton 9
fibers from cotton seeds; 10
(3) "Department", the Missouri department of natural 11
resources. 12
2. Notwithstanding any law, rule, order, decision, 13
permit, agreement, or other relevant authority to the 14
contrary, an owner or operator of a cotton gin that is not a 15
