Subject: Nevada 2009 Draft Annual Hg Emissions Reporting



### Hello gents,

Attached is the 2009 Annua l Emissions Reporting for the Mercury Program. It is near

final. The last step to finalization is to give industry a chance to review it for

typographical errors. We usually give them a week or so for review. We'll let you know

if anything changes.

W e are targeting Monday to get you guys the data dump for pre

- treat units and the test

PDFs shortly thereafter. I have a few folks out of the office that have some data to enter

1st thing on Monday morning so that we can get you all available data.

Hav e a great weekend.

- Rob

internal Barrick testing showed

a notable difference in

emissions with alkaline

conditions emitting more Hg to

the atmosphere. As this was

discovered in 2010, there is no
