FENCES Act

Introduced February 11, 2026

AI-Generated Summary

Updated February 26, 2026 at 5:25 AM UTC

The FENCES Act amends the Clean Air Act to clarify how emissions that originate outside the United States are treated when determining air‑quality standards. It says that foreign emissions count toward a state's air‑quality status regardless of whether they are caused by human activity, and it prevents a state from being labeled a nonattainment area if it would meet standards but for those foreign emissions. The bill also shields states from certain sanctions and fees when nonattainment is due to foreign emissions, exceptional events, or mobile‑source emissions that are beyond the state's control, provided the state shows it is fully implementing all controllable measures.

Key Provisions

  • Adds language to the Clean Air Act stating that foreign emissions are considered regardless of whether they result from human activity.
  • Prohibits designating any area within a state as nonattainment if the state can demonstrate it would meet the standard but for foreign emissions.
  • Creates a new section (179A) that exempts states classified as Severe, Extreme, or Serious from sanctions or fees if nonattainment is caused by foreign emissions, exceptional events, or uncontrollable mobile‑source emissions, assuming the state is fully implementing all controllable measures.
  • Requires states to renew their demonstration of exemption every five years to keep the sanction/fee relief in effect.

A BILL

To amend the Clean Air Act to clarify standards for emissions emanating from outside of the United States, and for other purposes.

1.

Short title

This Act may be cited as the Foreign Emissions and Nonattainment Clarification for Economic Stability Act or the FENCES Act.

2.

Emissions beyond control

(a)

Clarification of emissions covered

Section 179B of the Clean Air Act (42 U.S.C. 7509a) is amended—

(1)

by inserting (regardless of whether such emissions result from human activity) after but for emissions emanating from outside of the United States each place it appears; and

(2)

in subsection (d), by inserting (regardless of whether such emissions result from human activity) after but for emissions emanating from outside the United States.

(b)

Designations

Section 179B of the Clean Air Act (42 U.S.C. 7509a) is amended by adding at the end the following:

(e)

Designations

Notwithstanding any other provision of law, an area within a State may not be designated as a nonattainment area with respect to any new or revised primary or secondary national ambient air quality standard for a pollutant if such State establishes to the satisfaction of the Administrator that such area would be in attainment with such national ambient air quality standard for such pollutant but for emissions emanating from outside of the United States (regardless of whether such emissions result from human activity).

.

(c)

Applicability of sanctions and fees if emissions beyond control

Subpart 1 of part D of title I of the Clean Air Act is amended by inserting after section 179 (42 U.S.C. 7509) the following:

179A.

Applicability of sanctions and fees if emissions beyond control

(a)

In general

Notwithstanding any other provision of this Act, with respect to any nonattainment area that is classified under section 181 as a Severe Area or an Extreme Area for ozone or under section 188 as a Serious Area for particulate matter, no sanction or fee under section 179 or 185 shall apply with respect to a State (or an area or source therein) on the basis of a deficiency described in section 179(a), or the failure to attain a national ambient air quality standard for ozone or particulate matter by the applicable attainment date, if the State demonstrates that the State would have avoided such deficiency, or such standard would have been attained, but for one or more of the following:

(1)

Emissions emanating from outside the nonattainment area.

(2)

Emissions from an exceptional event (as defined in section 319(b)(1)).

(3)

Emissions from mobile sources to the extent the State demonstrates that—

(A)

such emissions are beyond the control of the State to reduce or eliminate; and

(B)

the State is fully implementing such measures as are within the authority of the State to control emissions from the mobile sources.

(b)

No effect on underlying standards

The inapplicability of sanctions or fees with respect to a State (or an area or source therein) pursuant to subsection (a) does not affect the obligation of a State, area, source, or other entity under other provisions of this Act to establish and implement measures to attain a national ambient air quality standard for ozone or particulate matter.

(c)

Periodic renewal of demonstration

For subsection (a) to continue to apply with respect to a State (or an area or source therein), the State involved shall renew the demonstration required by subsection (a) at least once every 5 years.
