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,

I'm so sorry but I completely forgot about my 1 pm conference call.  Are
you available after 4 pm?

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

Amanda-

Thanks 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.
