Thanks, Glenn. I just wanted to make sure I was rea ding it properly. **☺**

Talk to you soon,
Luke

Luke,

Yes, I am stating that the stored amount is the amo unt banked in equipment in use, so the term “charge d amount” or “amount currently in use in equipment” is a better description. (There is no estimate on the unused a mount in inventory in my e-mail, hopefully, I did not commun icate that incorrectly.)

I was using an estimated 10 percent annual leak rat e against all equipment – very rough estimate, but the lower AC leak rates balance out the higher refrigeration leak rat es.

Thanks, Glenn, for taking the time to walk me throu gh this today and for helping with my question last week. I have one additional follow-up question on this email. When y ou write “The annual emissions may represent only a bout 10 percent of the stored amount of R-22 used in refrig eration and AC systems in California. The stored a mount of R-22 in California alone may therefore exceed 100 million p ounds in use currently,” you’re referring to R-22 t hat is in use in existing equipment, not stored R-22 that is sitting unused in inventory, correct? It also appears you’ re assuming a 10% annual leak rate for all modeled equipment, correct ?

Thanks,
Luke

Luke,

Here’s the same e-mail sent to Mr. Williams of New Era Group, Inc.

Caveats on data: The following R-22 data is self-r eported by distributors and reclaimers operating in California, and has not been verified for accuracy. ARB estimates that between 70 and 80 percent of a ll refrigerant distribution in California is being rep orted, but this estimate has also not been verified

.

Data reported by Distributors Reporting in Californ ia Year R-22 Purchased or

received (lbs.) R-22 sold or distributed (lbs.) R-22 received and shipped

for reclaim, re-use, or destruction (lbs.) 2011 6,859,511 7,386,352 277,283 2012 7,249,358 5,677,406 221,534 2013 4,722,116 4,484,304 352,920

Data reported by Reclaimers Reporting in California Year R-22 Received by Reclaimers R-22 Reclaimed

in CA (lbs.) R-22 Shipped

out of CA for Reclaim (lbs.) R-22 Shipped out

of CA for Destruction (lbs.) 2011 185,283 120,839 90,820 820 2012 388,481 364,861 96,000 0 (zero) 2013 202,865 267,843 41,551 41,489

It is difficult to establish trends with only three years of data, however, we do see that the amount of R-22 received by reclaimers has decreased approximately 186,000 pounds, or 48% between 2012 and 2013. This decrease of R-22 received by reclaimers is greater than the decrease in purchases (-35%), and decrease in distribution (-21%). However, in the same timefram e of 2012 to 2013, the amount of R-22 shipped by distributors for reclaim did increase by 131,000 po unds, or 59%.

Further note that for all reporting years, the larg e difference between the amount of refrigerant dist ributed, and the amount recovered for reclamation. For example, in 2013, the total amount of recovered R-22 report ed was approximately 556,000 pounds (distributors plus rec laimer reports), compared to 4.48 million pounds of R-22 distributed, indicating that almost 90 percent of r efrigerant distributed is not recovered, and is ass umed to be emitted.

Other R-22 estimated emissions in California. Please note that R-22 emissions have also been esti mated using an additional approach (other than sale s and reclamation data reported to us) where we consider the many different sources of R-22. For the year 2 013, we3 estimate that approximately 11.7 million pounds of R-22 were emitted in California from commercial refrigeration and AC and residential AC, with a sma ller amount (0.2 million pounds) from lesser source s, including bus and ship/marine vessel AC, and insula ting foam. Using a global warming potential value (GWP) of 1810, this is equivalent to 9.8 million metric t onnes of carbon dioxide equivalents (MMTCO 2 E). For comparison, the 9.8 MMTCO 2 E emissions from R-22 by itself represents 21 perce nt of all fluorinated gas emissions in California, and would be almost 2 perc ent of all GHG emissions in California (448 MMTCO 2 E total in 2011), if ozone-depleting substance emissi ons were included in the inventory, which they are not because ODS are phased out as part of the Montreal Protocol. For further perspective, 9.8 MMTCO 2 E in emissions is equivalent to the greenhouse gas emiss ions of:

1.3 million homes’ electricity use for an entire ye ar 2 million passenger vehicles for an entire year Burning 1.1 billion gallons of gasoline Burning 10.5 billion pounds of coal

Estimates from the U.S. EPA Greenhouse Gas Equivale ncies Calculator at: http://www.epa.gov/cleanenergy/energy-resources/cal culator.html

.
The annual emissions may represent only about 10 pe rcent of the stored amount of R-22 used in refriger ation and AC systems in California. The stored amount of R- 22 in California alone may therefore exceed 100 mil lion pounds in use currently.

Hope this is useful. As I stated earlier, CARB doe s not have any official comment/outlook/position on the R- 22 allocation at this time.
