(a) Reclaimed Refrigerant Use Requirements for Manufacturers of AC Equipment 
Subject to Effective Date of January 1, 2025, in Table 3 of section 95374(c) . Equipment 
manufacturers shall determine the number of pounds of certified reclaimed R -410A 
refrigerant use required as follows: 
(1)Use the following equation to determine baseline average pounds per year: 
Baseline Average Pounds of Refrigerant in 2018 and 2019 = [(pounds in 
AC equipment entered into California in 2018 + pounds in AC equipment entered into California in 2019) ÷ 2]. 
(2) Applying the calculated baseline average pounds, determine the number of 
pounds of certified reclaimed R -410A refrigerant use required annually, using the 
following equations: 
Annual Reclaim Use Requirement for 2023 =  [(10% × baseline average 
pounds calculated in (a)(1)) × 1.04 (a one- time growth factor of 4%)]. 
Annual Reclaim Use Requirement for 2024 =  [(10% × baseline average 
pounds  calculated in (a)(1)) × 1.04 (a one- time growth factor of 4%)]. 
(3)For AC manufacturers with no shipments into California in 2018 and 2019, the 
baseline years shall be 2023 and 2024. Projected shipments into California shall be used to calculate the certified reclaimed refrigerant requirements for the initial 
baseline report and first annual report, while actual shipments into California will 
be used for the final annual report. The following equation shall be used to 
determine the number of pounds of certified reclaimed R -410A refrigerant use 
required annually: 
Annual Reclaim Use Requirement for 2023 and 2024 = (10% × pounds in 
AC equipment entered into California per year). 
(4)The requirement shall be met by AC manufacturers by any or all of the 
following:

manufacturers shall determine the number of pounds of certified reclaimed R -410A 
refrigerant use required as follows: 
(1)Use the following equation to determine baseline average pounds per year: 
Baseline Average Pounds of Refrigerant in 2018 and 2019 = [(pounds in 
VRF equipment entered into California in 2018 + pounds in VRF equipment 
entered into California in 2019) ÷ 2]. 
(2)Applying the calculated baseline average pounds per year, determine the 
number of pounds of certified reclaimed R- 410A refrigerant use required 
annually, using the following equations: 
Annual Reclaim Use Requirement for 2023 = [(15% × baseline average 
pounds calculated in (b)(1)) × 1.10 (a one- time growth factor of 10%)]. 
Annual Reclaim Use Requirement for 2024 = [(15% × baseline average 
pounds calculated in (b)(1)) × 1.10 (a one- time growth factor of 10%)]. 
Annual Reclaim Use Requirement for 2025 = [(25% × baseline average 
pounds calculated in (b)(1)) × 1.10 (a one- time g rowth factor of 10%)]. 
(3)For VRF manufacturers with no shipments into California in 2018 and 2019, 
the baseline years shall be 2023, 2024, and 2025. Projected shipments into California shall be used to calculate the certified reclaimed refrigerant 
requi rements for the initial baseline report and first annual report, while actual 
shipments into California will be used for the subsequent annual reports. The following equation shall be used to determine the number of pounds of certified 
reclaimed R -410A refrigerant required annually: 
42     
   
     
  
    
 
 
 
  
 
  
   
 
  
  
  
  
  
    
  
  
 
  
 
  
 
 
  
  Annual Reclaim Use Requirement for 2023 and 2024 = (15% × pounds in

  (K)For variance requests based on impossibility, quantification of current GHG 
emissions resulting from normal business -as-usual operations as it directly 
relates to the continued use of any substance in end- uses listed in Table 1, 
section 95374(a); Table 2, section 95374(b); Table 3, section 95374(c); or Table 
4, section 95374(d). This includes quantification of the direct GHG emissions 
resulting from refrigerant leaks or HFC emissions and indirect GHG emissions 
resultin g from energy use (where applicable), with all calculations, based on the 
average lifetime of the equipment or product that will continue to use prohibited 
substances. Applicant must include all calculations used to calculate GHG 
emissions estimates, including emission factors (i.e., charge size as defined in section 95373, leak rate as defined in 40 C.F.R. Part 82.152, and refrigerant 
used over the average lifetime of the equipment, system, or product); 
(L)Description of any negative impacts to human health or the environment that 
may result from the granting of a variance; (M)A mitigation plan that demonstrates how the Applicant will reduce excess 
GHG emissions to a level equal to or below what would have been emitted had 
the Applicant been in compliance and how the Applicant will mitigate any 
negative impacts to human health or the environment. The Applicant must 
include all calculations used to calculate GHG emissions estimates, including emission factors (i.e., charge size as defined in section 95373, leak rate as 
defined in 40 C.F.R. Part 82.152, and refrigerant used over the average lifetime of the equipment, system, or product). This may include an analysis of options to minimize usage of prohibited substances, efforts to reduce leaks or venting of 
prohibited substances, and options to recycle or destroy high- GWP refrigerant(s); 
and 
(N)A detailed explanation of efforts that may be implemented to curtail 
noncompliance in lieu of obtaining a variance. 
(2)The Applicant shall certify under penalty of perjury that they are a Responsible 
Official with authority to submit the application, implement any provision of an Executive 
Order, and that all information provided is true and accurate to the best of the 
Applicant’s knowledge, after conducting due diligence. Applications without this 
certification will be automatically denied. 
(3)All applications and documentation relating to the variance shall be submitted to 
CARB  at HFCREDUCTION@ARB.CA.GOV. 
(4)Applications and supporting documents shall be written in English. 
(5)Any Applicant submitting information to the Executive Officer pursuant to this section 
may claim that information to be “confidential” by clearly identifying the information as
