The treatment media will consist of two, 500-pound, 1200 virgin <br /> coconut shell granular activated carbon. The removal efficiency of virgin coconut shell GAC is <br /> usually more than 99%. <br /> The two 500-pound vessels will be connected in series. They will have sample ports before and <br /> after each vessel for monitoring the process water. The water will be pumped from the two <br /> extraction wells, through the GAC vessels,to the storage tank. We will sample the water after the <br /> GACs to demonstrate that the contaminants are removed. Is this work acceptable to you such that <br /> we can proceed with purchase and installation of GACs? <br /> If you have any questions,please call me at(949) 768-6210 or send me an email. <br /> Thank you very much, <br /> S.

We will issue <br /> the permit to discharge on site which will include monitoring frequencies. <br /> Erich <br /> From: Javad Masoudi rmailto:imasoudi(alemscorp.us] <br /> Sent: Thursday, December 18, 2014 9:55 AM <br /> To: Erich Delmas <br /> Cc: DZumberge(ftotmail.com; 'Vicki McCartney'; GOsterkamoCaosterkamporp.com; Kuldeep Sharma; <br /> 'Marshall, James@Waterboards' <br /> Subject: RE: Frontier Sampling <br /> Good morning Erich, <br /> We are going to dispose of this load of water at the Seaport Env. Facility in Redwood City. <br /> From now on, we want to pretreat the well water through granular activated carbon such that we <br /> remove gasoline contaminants (such as MTBE and TBA) and be able to release the water into the <br /> sewer facility. Please look at the analytical report and confirm that there are not any other <br /> constituents in the water(besides gasoline components) that may concern you. <br /> Right now I am looking for the suppliers of GACs in the Tracy area. Do you know anyone? <br /> I have not had any water treatment project in Tracy. Should I go through any permitting process to <br /> 1/16/2015 <br />
