Regulatory Relief for Certain Stationary Sources To Promote American Chemical Manufacturing Security

Proclamation 10957 of July 17, 2025

Regulatory Relief for Certain Stationary Sources
To Promote American Chemical Manufacturing Security

By the President of the United States of America

A Proclamation

1. The United States relies on a strong chemical
manufacturing sector to support industries like energy,
national defense, agriculture, and health care. These
facilities produce essential inputs for critical
infrastructure, advanced manufacturing, medical
sterilization, semiconductors, and national defense
systems. Maintaining a robust domestic chemical
industry is vital to safeguarding the supply chains
that underpin our economy and to reducing the Nation's
dependence on foreign control over materials critical
to national resilience. As adversaries expand influence
over key inputs, continued domestic production is
essential not only to economic resilience but also to
military readiness, public health, and national
preparedness.

2. On May 16, 2024, the Environmental Protection Agency
published a final rule titled New Source Performance
Standards for the Synthetic Organic Chemical
Manufacturing Industry and National Emission Standards
for Hazardous Air Pollutants for the Synthetic Organic
Chemical Manufacturing Industry and Group I & II
Polymers and Resins Industry, 89 FR 42932 (HON Rule).
The HON Rule imposes new emissions-control requirements
on certain chemical manufacturing facilities, some of
which were promulgated pursuant to section 112 of the
Clean Air Act, 42 U.S.C. 7412.

3. The HON Rule imposes substantial burdens on chemical
manufacturers already operating under stringent
regulations. Many of the testing and monitoring
requirements outlined in the HON Rule rely on
technologies that are not practically available, not
demonstrated at the necessary scale, or cannot be
implemented safely or consistently under real-world
conditions. For many facilities, the timeline for
compliance as set forth at 89 FR 42953-42955 would
require shutdowns or massive capital investments before
any proven pathway to compliance exists. The HON Rule
imposes requirements that assume uniform technological
availability across facilities, despite significant
variation in site conditions, permitting realities, and
equipment configurations. A disruption of this capacity
would weaken key supply chains, increase dependence on
foreign producers, and impair our ability to respond
effectively in a time of crisis. These consequences
would ripple across sectors vital to America's growing
industrial strength and emergency readiness.

NOW, THEREFORE, I, DONALD J. TRUMP, President of the
United States of America, by the authority vested in me
by the Constitution and the laws of the United States,
including section 112(i)(4) of the Clean Air Act, 42
U.S.C. 7412(i)(4), do hereby proclaim that certain
stationary sources subject to the HON Rule, as
identified in Annex I of this proclamation, are exempt
from compliance with those aspects of the HON Rule that
were promulgated under section 112 of the Clean Air
Act, 42 U.S.C. 7412 for a period of 2 years beyond the
HON Rule's relevant compliance dates (Exemption). This
Exemption applies to all compliance deadlines
established under the HON Rule applicable to the
stationary sources listed in Annex I, with each such
deadline extended by 2 years from the date originally
required for such deadline. The effect of this
Exemption is that, during

each such 2-year period, these stationary sources will
be subject to the emissions and compliance obligations
that they are currently subject to under the applicable
standard as that standard existed prior to the HON
Rule. In support of this Exemption, I hereby make the
following determinations:

a. The technology to implement the HON Rule is not
available. Such technology does not exist in a
commercially viable form sufficient to allow
implementation of and compliance with the HON Rule by
the compliance dates in the HON Rule.

b. It is in the national security interests of the
United States to issue this Exemption for the reasons
stated in paragraphs 1 and 3 of this proclamation.

IN WITNESS WHEREOF, I have hereunto set my hand this
seventeenth day of July, in the year of our Lord two
thousand twenty-five, and of the Independence of the
United States of America the two hundred and fiftieth.
