# Thank you Jeremy, this is very helpful. Best, heidi -----Original Message----- From: Arling.Jeremy@epamail.epa.gov [mailto:Arling.Jeremy@epamail.epa.gov] Sent: Thursday, April 15, 2010 3:39 PM To: King, Heidi R. Cc: Brennan.Ross@epamail.epa.gov Subject: MeBr Calculation

Heidi Here is an annotated version of the spreadsheet that shows the calculation of Stocks and New Production allocations. (See attached file: 2010 Allocation calculation.xls) I was looking at the wrong line on a different spreadsheet open when I said the change in the CSA between the proposed and the final was only 17,000 kg. That is the sum of the changes due to the revised carryover and the new decision by the Parties (cells E6 and E27 in the version Im attaching here) Let me know if you have any additional questions.
