and, in the summer of 2024, exceeded the United States environmental7
protection agency's ozone limits for 40 days;8
(c) In May of 2023, the United States environmental protection9
agency issued a limited disapproval of Colorado's state implementation10
plan after finding that Colorado's practice of providing emissions records11
to the state only on request did not sufficiently allow practical public12
access to information necessary to determine compliance with the "Clean13
Air Act";14
(d) In July of 2023, Colorado's attorney general filed a petition15
with the United States court of appeals for the tenth circuit for review of16
the United States environmental protection agency's disapproval;17
(e) The case settled, and the new presidential administration18
rescinded the rule allowing Colorado to continue the current practice of19
making air pollution records available to the state upon request, but not20
making the records accessible to the public;21
(f) Air pollution emissions travel from a polluter's private property22
into the air of other private property owners and into public spaces;23
HB26-1121-2-

emitted into the air they breathe and onto the property they own;2
(h) Pollution records are now kept in easily accessible electronic3

"Clean Air Act";5
(i) The cost of electronic database storage for records is nominal,6
ranging from one cent to 20 cents per gigabyte; and7

of Colorado residents to require that pollution records be both available9
to the state for inspection and accessible to the public.10
