Hi Amanda and Dianne,

Unfortunately after 4pm today does not work for us.

Does Monday 3/22 at 9:00 AM or 2:00 PM or Tuesday 3/23 afternoon work?

Thanks so much,

Cheers,

Monica

Hi Amanda and Dianne,

Unfortunately Cindy has a meeting that runs all morning and finishes at 2:00. 

Cindy might be able to leave the meeting a little early - around 1:45pm. 

Would you be able to quickly chat at 1:45? I understand that is very little 

time but enough to get the conversation started.

Cheers,

Monica

AmandaThanks so much for providing these comments from EOP. Monica and I have some 

clarifying questions. Can we set up a quick call later this week to ensure 

we're generating the right types of information?

Hi Monica,

Please find EOP consolidated comments on EPA’s HC SNAP NPRM. We are happy to 

chat about them. Please let me know when you want to discuss.

Thanks!

Amanda

 1. There is considerable discussion, as there should be, throughout

 the document on the flammability risks to public health posed by

 the substitutes. However, CEQ suggests a distinct discussion be

 added on how the anticipated environmental benefits outweigh the

 flammability risks. The substitutes carry an A3 Refrigerant

 Safety Group Classification code. We understand EPA proposes use

 conditions to mitigate flammability risks, but it would be helpful

 to know if and how the environmental benefits compare to the

 weight of the flammability risks.

 2. Broad flammability risks associated with manufacturing and

 transportation are only weakly noted in the document. Has EPA

 coordinated with the DOC and DOT on its goal to introduce these

 substitutes in refrigeration units?

 3. Acute Exposure Guideline Levels were used to assess end-use

 exposure to propane, but not for the other substitutes. As EPA

 notes AEGLs consider flammability in addition to toxicity. Why

 not use AEGLs for all of the substitutes?

 4. Page 18 line 14, page 20 line 19: refrigerant in units of pounds

 but elsewhere in the document refrigerant masses are in grams.

 Grams should be used throughout.

 5. Page 25: In the section on “impacts on the environment,” there is

 useful information on how the hydrocarbon refrigerants compare

 with the chemicals they would replace on GWP basis. However,

 CEQ suggests EPA include a brief discussion of how the

 replacements compare with the original chemicals on the basis of
 lifecycle GHG emissions from the intended uses—i.e., accounting

 for energy consumption as this is currently lacking.

 6. Page 41 line 8: use of “a” hydrocarbon or use of hydrocarbons

 (pl)

 7. Page 47 Section G: It is noted that this action does not present

 a disproportionate risk to children. However, given that a) on

 page 29 it’s noted “the highest concentrations of the refrigerant

 occur in the lower stratum of the room when assuming lower

 ventilation levels of 2.5 air changes per hour” upon the 100

 percent discharge of a unit, and b) children spend a significant

 amount of time in the kitchen, further rationale for stating there

 is a negative disproportionate risk to children with respect to

 this proposal would strengthen this section.
