II. Background

Subsection (i) of the American Innovation and Manufacturing Act of 2020 (AIM Act or Act),[1] entitled “Technology Transitions,” provides that a person may petition the Administrator to promulgate a rule for the restriction on use of a regulated substance [2] in a sector or subsector. Once EPA receives a petition under this subsection, the AIM Act directs the Agency to make petitions publicly available within 30 days of receipt, and to grant or deny the petition within 180 days of receipt.

On April 13, 2021, the Agency received five petitions under subsection (i) of the AIM Act. We have established the docket to this notice to make these petitions publicly available, and to post letters of support and other submitted material for public accessibility. Table 1 below lists the petitions received by EPA on April 13, 2021, and each petition's docket document ID number. Going forward, EPA intends to also use this docket to post petitions and other relevant information submitted under subsection (i) of the AIM Act.

Although not required under the statute, EPA welcomes additional data and relevant material to aid in its evaluation of petitions, based on the factors identified in the next section of this notice of data availability (NODA) and specified in subsection (i) of the AIM Act. Stakeholders should note that EPA is not soliciting information on any topic other than the posted petitions under subsection (i) through this notice. Public submissions that pertain to issues beyond the scope of this NODA will not be considered.

III. What information does EPA consider when making a determination on a petition?

Subsection (i) of the AIM Act identifies certain factors for the Agency to consider when making a determination to grant or deny a petition. Specifically, subsection (i)(4) of the Act requires EPA to factor in, 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.

EPA invites relevant data related to the factors listed above for the petitions posted in the docket.[3] Any information submitted in response to this NODA should include the name of the petitioner(s) and the petition document ID number.

Subsequent petitions received by the Agency under subsection (i) will also be posted in this docket within 30 days of receipt, as well as on the Agency's website at​climate-hfcs-reduction/​petitions-under-aim-act. Interested entities may sign up to receive notification when new petitions are posted by following the instructions at this website. EPA invites relevant information regarding those petitions from the public to be submitted to the docket by the deadline provided on the website.

IV. What happens after EPA makes a determination on a petition?

Where the Agency grants a petition submitted under subsection (i) of the AIM Act, the statute requires EPA to promulgate a final rule not later than two years from the date the Agency grants the petition. Per subsection (i)(1) of the AIM Act, EPA may issue rules that “restrict, fully, partially, or on a graduated schedule,” the use of a regulated substance in the sector or subsector in which the regulated substance is used. The Act establishes that no rule developed under subsection (i) may take effect earlier than one year after the rule promulgation date. In addition, prior to issuing a proposed rule under subsection (i), EPA must consider negotiating with stakeholders Start Printed Page 28101in the sector or subsector in accordance with negotiated rulemaking procedures.[4] If the Agency decides not to undergo a negotiated rulemaking, the AIM Act requires the Agency to publish an explanation of its decision not to use that procedure.

For petitions which have been denied, the Agency will publish in the Federal Register an explanation of the denial.
