Harlin Knoll [EH] <br /> From: Timothy Cuellar[tcuellar@advgeoenv.com] <br /> Sent: Tuesday, December 07, 2004 11:30 AM <br /> To: Harlin Knoll [EH] <br /> Subject: RE: sierra lumber <br /> sure. . . . .I am actually sending you last quarter's report today; <br /> presently, I have all air sparge lines 'on-line' (wells AW-1 thorugh AW-5 <br /> and MW-4B) ; AW-1 through AW-5 are sparging at psi rates between 5-8 psi and <br /> MW-4B is sparging between 13-15 psi. Rick has set the air compressor to <br /> operate on and off in 3 hour intervals. <br /> For SVE wells, we only have SVE wells VW-1 and VW-6 open; all the other SVE <br /> wells are closed. I tried openning VW-4 (in the middle of road) , but for <br /> whatever reason, this well during the rainy season will bring a lot of <br /> liquid/condensate to the knock out drum (will fill two 55-gallon drums over <br /> night) . . . . .so I have this well closed. I am going to have Chris open up <br /> well VW-2 today to increase the air flow in the system. We currently have <br /> about 25 cfm coming into the system. <br /> The July, August, September air samples came back 220 ug/1, 550 ug/l and <br /> 280 ug/l (within the norm) , but the October sample spiked up to 1, 100 ug/l <br /> and the November sample came back down to 540 ug/l. Hope this info <br /> helps. . . . . . .Tim <br /> -----Original Message----- <br /> From: Harlin Knoll [EH] [SMTP:HKnoll@sjcehd.com] <br /> Sent: Tuesday, December 07, 2004 8:28 AM <br /> To: tcuellar@advgeoenv.com <br /> Subject: RE: sierra lumber <br /> TJC: <br /> Not a problem. Maybe you can give me an update on the air sparging <br /> operation: points where injection is occurring; PSI; flow rates; on and off <br /> cycles, etc. <br /> Hk <br /> --Original Message----- <br /> From: Timothy Cuellar [mailto:tcuellar@advgeoenv.com] <br /> Sent: Monday, December 06, 2004 3:37 PM <br /> To: Harlin Knoll [EH] <br /> Subject: sierra lumber <br /> Harlin, <br /> I would like to schedule a Sierra Lumber QM for this Tuesday between 9-2 at <br /> wells MW-1, MW-2, MW-4A/B, MW-6 and MW-8; let me know if this poses any <br /> problems.
