II. Background The Agency is providing information in preparation for upcoming regulatory actions under the American Innovation and Manufacturing Act of 2020 AIM
Act or Act, included in the Consolidated Appropriations Act, 2021.
Among other provisions, the Act directs EPA to develop a U.S. production baseline and a U.S. consumption

baseline and to phase down hydrofluorocarbon HFC production and consumption relative to those baselines.1 The legislation specifies that the production and consumption baselines are equal to the sum of 1 the average annual quantity of all HFCs regulated under the Act that were produced or consumed, respectively, in the United States during the period beginning on January 1, 2011 and ending on December 31, 2013; 2 the quantity equal to the sum of 15 percent of the production or consumption, respectively, of hydrochlorofluorocarbons HCFCs in calendar year 1989; and 3 0.42 percent of the production or consumption, respectively, of chlorofluorocarbons CFCs in calendar year 1989.
EPA is seeking comment on the accuracy of the data and analyses presented in this notice and the draft reports in the docket to this notice and welcomes input on those data and potential data gaps. Data is available in this notice and will be available in the docket, and additional data will be added to the docket on February 8, 2021. Data from 2011 through 2013 will be helpful in developing the U.S. HFC
baselines for production and consumption. Readers should note that EPA will only consider comments about the data presented in this notice and the draft reports provided in the docket and is not soliciting comments on any other topic through this notice. The Agency is also not seeking comment on the historic HCFC and CFC consumption and production values as the Agency already has those data and no further information is needed. Based on feedback provided through this NODA
process and other stakeholder engagement, EPA intends to revise and release updated numbers for 20112013
at the same time the Agency issues a proposed rule to establish baselines and an HFC allocation system consistent with the AIM Act.
EPA is also providing separate documents in the docket related to the applications for which section e4Biv of the AIM Act directs the Administrator to allocate the full quantity of allowances necessary, based on projected, current, and historical trends. Similar to the data being provided related to the consumption and production baselines, EPA is providing the public with reports related to the applications listed for these mandatory allocations so that the 1 The AIM Act defines consumption as the quantity produced and imported in the United States minus the quantity exported from the United States.

public can view what data EPA
currently has, comment on currently available information, and provide information on potential data gaps. The docket to this NODA contains documents for the following statutorilyestablished applications: 1 Propellants in metered dose inhalers MDIs; 2
defense sprays; 3 structural composite preformed polyurethane foam for marine use and trailer use; 4 the etching of semiconductor material or wafers and the cleaning of chemical vapor deposition CVD chambers within the semiconductor manufacturing sector; and 5 on board aerospace fire suppression. These reports describe EPAs current awareness of the use of HFCs and provide information on EPAs current knowledge on projected, current, and historical trends of HFC related to these statutorily identified applications. EPA
requests comment on the data and analysis in these documents.
As stated throughout this notice, EPA
plans to undergo a future notice and comment rulemaking process, which will be a separate action, that will outline the Agencys approach to calculating HFC production and consumption baselines, allocating allowances in furtherance of the HFC
phasedown, and defining applications for mandatory allocations. EPA will solicit public feedback on these issues through that separate notice and comment process, and therefore is not accepting public comment on these matters through this NODA. Public comments that pertain to issues beyond the scope of this NODA will not be considered. To the extent such comments are relevant to the previously referenced future and separate rulemaking, those comments should be resubmitted through that future rulemaking process in order to ensure that they are duly considered by the Agency. The list of companies in Table 2 is provided solely as an illustration of the sources of the net supply data currently in the Greenhouse Gas Reporting Program GHGRP for the years 2011, 2012, and 2013. The list should not be interpreted as any indication concerning future Agency decisions about the companies that will be allocated allowances pursuant to AIM Act regulations, since those are the three years defined in the AIM Act for calculating the baseline numbers. Use of AIM Act terminology in this NODA is for communication purposes only and should not be viewed as indications of how EPA will define these terms in future rulemaking actions.
The AIM Act will be implemented over time. EPA intends to provide more
