Once <br /> Nuel has received this information,-I will respond by letter concerning the three additionalproposed ozone Welis. <br /> i <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br />{ Environmental Health Department <br /> i 600 East Main Street <br /> JStockton, California 95202 <br /> Phone: (209)468-9852 <br /> Fax: (209)468-3433 <br /> Email: vmccartnev a)sicehd.com. <br /> E <br /> From: Ally Colavita [mailto:acolavita@advgeoenv.com] <br /> Sent: Friday, February 29, 2008 3:26 PM ' <br /> To: Vicki McCartney [EH] <br /> Cc: 'bill; Art ; Robert Marty <br /> Subject: Stefano's Gas (141.9 East Charter Way, Stkn) <br /> Hi Vicki--- <br /> wanted to inform you that t am the new project manager for.the site Stefano's Gas (1419 East Charter <br /> Way, Stkn). In.addition,. I wanted to respond to the END-prepared letter dated 02 January 2008. <br /> -AGE concurs with the EHD's recommendation to relocate the CPT boring approximately twelve feet south <br /> i of the location proposed in the AGE-prepared Work Plan Addendum dated 19 November 2007. <br /> AGE provides the following comments to the EHD-questions/statements: <br /> "How many pounds of ozone are currently being injected dail <br /> Y?' <br /> According to the manufacturer; Aries Tek, the ozone sparge.system at Stefano's (EnviroSparge 11), s <br /> r injects one pound of ozone into the subsurface per day; however this figure does not account for <br /> downtime between cycles. The EnviroSparge 11 injects ozone into ozone wells at a rate of 130 <br /> minutes per well per cycle. At the cessation of a cycle; the.EnviroSparge II has a downtime of 20 <br /> minutes. Utilizing the existing three ozone wells at the site, 390 minutes of the cycle is attributed to <br /> i injecting ozone into each well at increments of 130.minutes. Fallowing the 390-minute cycle, the <br /> system has a downtime of 20 minutes. Therefore, the system completes approximately 3.5 cycles - <br /> per day with an approximate average downtime of,70'.minutes per day. Accounting for downtime, <br /> the EnviroSparge 11 injects approximately 0.95 pounds of ozone into the.subsurface per day_ <br /> i <br /> t <br /> 3/3/2008. <br />. t <br />
