Interagency	Comments	on	U.S.	Environmental	Protection	Agency	(EPA)	draft final	rule	titled,

“Protection	of	Stratospheric	Ozone: Change	of	Listing	Status	for	Certain	Substitutes	Under

the	Significant	New	Alternatives	Policy	(SNAP)	Program,”	(RIN 2060-AS18)

It looks like there is some overlap between the DOE Automatic Commercial Ice Maker (ACIM) energy 

efficiency standards and the SNAP rule. EPA indicated that only the ice makers that are connected to 

supermarket remote condensing systems are affected by the SNAP rule. Referring below to the DOE 

Automatic Commercial Ice Maker energy efficiency standards that go into effect in January 2018, DOE has 

standards for both batch and continuous ice makers that each cover two types of remote condensing units 

including: (1) Remote Condensing (but not remote compressor) and (2) Remote Condensing and Remote 

Compressor. Is there any overlap in between the DOE ACIM and SNAP supermarket systems 

requirements? If so, it would appear that the EPA SNAP requirements for supermarket systems is one year 

ahead of the DOE ACIM requirements.

Amended New Standards

Beginning in January, 2018, automatic commercial ice-making equipment producing cube ice with harvest rates 

between 50 and 2,500 lb of ice per day shall meet the amended energy consumption standards shown on 

Table 2. Standards shown on Table 2 for batch type ice-makers represent amendments to existing standards 

set for cube type ice makers, and new standards for cube type ice makers with expanded harvest capacities up 

to 4,000 pounds of ice per 24 hour period (lb ice/24 hours) and an explicit coverage of other types of batch 

machines, such as tube type ice makers.

The December 2014 Final Rule provides new standards for continuous type ice-making machines, which were 

not previously currently covered by DOE’s existing standards. Beginning in January, 2018, each automatic 

commercial ice maker producing flake or nugget ice (and other ice produced by way of continuous processes) 

shall meet the energy consumption standards shown on Table 3.
