Technology Transition Petitions under the AIM Act

Logo of EPA's HFC Phasedown program under the American Innovation and Manufacturing (AIM) Act

The AIM Act includes provisions to support industry’s transition to next-generation technology. Under subsection (i) of the AIM Act, entitled “Technology Transitions,” on its own initiative, EPA may by rule restrict, either fully, partially, or on a graduated schedule, the use of HFCs in sectors or subsectors where they are used. A person may also petition EPA to promulgate such a rule. Once EPA receives a petition under subsection (i), the AIM Act directs the Agency to evaluate the petition and to grant or deny the petition within 180 days of receipt.

How to Submit Petitions Under Subsection (i) of the AIM Act

Due to the current limited access to the Agency mailroom while employees telework, and to facilitate timely receipt of your petition, please submit petitions electronically here.

*Note that the Agency will consider comments received by these deadlines in its evaluation to grant or deny petitions to meet the statutory deadlines required under the AIM Act. EPA may also consider information submitted after the deadlines in its decision on petitions or in developing any rulemaking related to petition(s) submitted under AIM Act subsection (i).

How Petitions will be Evaluated

The AIM Act identifies certain factors for the Agency to consider when evaluating a petition that has been submitted under subsection (i). Specifically, the Act requires EPA to consider, to the extent practicable:

(1) the best available data;

(2) the availability of substitutes for use of the regulated substance that is the subject of the petition, in a sector or subsector, taking into account technological achievability, commercial demands, affordability for residential and small business consumers, safety, consumer costs, building codes, appliance efficiency standards, contractor training costs, and other relevant factors, including the quantities of regulated substances available from reclaiming, prior production, or prior import;

(3) overall economic costs and environmental impacts, as compared to historical trends; and

(4) the remaining phase-down period for regulated substances under the final rule issued under subsection (e)(3) of the AIM Act, if applicable.

Furthermore, the AIM Act specifies that EPA shall consider these factors when carrying out subsection (i):

(1) evaluate substitutes for regulated substances in a sector or subsector, taking into account technological achievability, commercial demands, safety, overall economic costs and environmental impacts, and other relevant factors; and

(2) make the evaluation under subparagraph (A) available to the public, including the factors associated with the safety of those substitutes.
