### TOPICS DISCUSSED AND ACTION TAKEN

I c alled Veolia Water HQ on 9/27/11 at 2:45 PM. The o perator redirected me to a sales manager, Michelle

Cline. I l eft a voicemail and explained what I was calling about.

I c alled a different Veolia Water office on 11/1/11 at 10:30 AM and spo ke with Michele Mi g liavacca, an engineer and manager. After discussing the project and ERG ’s role as a contract or to EPA, Michele informed

me that he would provide presentations in an email to answer more specific questions we may have. We spoke

for a little over half an hour on the following topics:

General: Veolia offers three main technologies that apply to shale gas wastewater: OPUS (reverse osmosis), MULTIFLO (softening), and an evaporator (unsure the name of this technology ) . First, Michele pointe d out that

the decision for which technology operators use depends on influent concentration of TDS and “methanol.” He classified “methanol” as BOD, TOC, and other organic compounds.

R.O.: The OPUS reverse osmosis unit can handle TDS concentrations up to approximately 30,000 mg/L. T he

OPUS units are not mobile and must be operated at permanent sites. Recently, Veolia added the OPUS II to their line of wastewater treatment units. The OPUS II includes chemical precipitation within the reverse osmosis unit. I t also uses new ceramic membranes. Michele stated the OPUS is not used to treat shale gas wastewater on a large scale

, but he indicated that pilot studies may be in progress. Michele began providing energy consumption data, but said it wa s to o hard to expl ain over the phone because of the variables involved (energy consumption ranges widely depending on the flow volume, influent TDS, and desired TDS ). He offered

to send me specific energy usage per volume via email.

Softening: The MULTIFLO is a softening tr eatment unit that Veolia offers to the shale gas industry. These units are mobile and may be used for pretreatment for the OPUS I (the OPUS II contains technology similar to

the MULTIFLO and therefore it is not used with the OPUS II).

Evaporators: Michele also talked about Veolia evaporators, which are mechanical vapor compression units.

These units are mobile and are capable of treat ing about 3 gpm ( 100 to 150 bbl per day ) . He commented that evaporation is best suited for Marcellus wastewater because of i ts ability to handle high TDS water

. E vaporation/distillation requires the least amount of pretreatment , but o il and TSS should be removed through pretreatment if using evaporation. Michele commented that low boiling VOC’s (in the boiling range of water) in wastewater may evaporate with the water and condense into the treated wastewater (distillate).

In order to save time, Michele said he would email presentations with more information on each technology by

the end of the week

. I sent him an email at michele.migliavacca@veoliawater.com following the phone call in order to exchange contact information.
