Hammer Lane, Stockton <br /> Hi Sarah, <br /> I am available that week to meet. Perhaps you could submit an agenda to review. I nee; <br /> one to justify a meeting to my- management. <br /> My primary concerns with the ozone sparging are: <br /> Did Secor sample..formetals-_.and.general .minerals, including.,-total, and hexavalent chromium, <br /> and bromide/bromate?'� <br /> If so, were there any increases and if so, -did` they decline after ozone injection ceased? <br /> Reporting limits for the data would need to be- low enough for comparison to Region 5 Water <br /> Quality Goals. <br /> Also, my recommendation would..be..for--you-to-putweverything into a 'report, .evaluating the <br /> data- and geology for both- sites with a proposal for 'a workplan' to conduct a'pi'l'ot -study <br /> at your site. If there is a correlation between sites and no problems, resulting. from <br /> ozone injection, then you might submit a workplan with the report Of•- course,w-Vicki has <br /> the final say on the site. <br /> Thanks. <br /> Jim Barton <br /> James L.L.

I was hoping to start some <br /> dialogue again on this and to try to .setup a meeting between Stratus, San Joaquin, and <br /> RWQCB to continue our discussions on this site, with respect to moving this site into <br /> remediation (via the previously San Joaquin Co approved ozone route) . How do your <br /> schedules look for the week of May 5 through 9? I'd prefer something around loam, if <br /> possible maybe on the 6th or 7th? We could meet at RWQCB's offices in Rancho Cordova or <br /> at SJC's offices in Stockton - whatever is convenient for you both. Thanks, have a good <br /> one, <br /> -sarah <br /> Sarah O.
