I <br /> 4)For anaerobic bacteria, nitrogen and methane, in addition to carbon dioxide and oxygen <br /> must be monitored. According to the CVRWQCB, anaerobic bioremediation is much less <br /> efficient than aerobic bioremediation and is a much more lengthy process. <br /> i <br /> The H-10 bacteria are not anaerobic. They are microaerophilic meaning they can survive in <br /> very low oxygen environments(2 ppm). No additional nitrogen,methane,.carbon dioxide or <br /> oxygen will be supplied to the subsurface. <br /> As stated,our bioremediation application is an aerobic process and is more efficient than <br /> anaerobic degradation. <br /> 5)A permit to apply the bacteria to soil and groundwater, or a waiver of the permit <br /> requirements, must.be.obtained.from_the CVRWQCB. i <br /> As with other sites in California,we expect to apply for a for a waiver of the permit <br /> requirements for waste discharge. The only byproducts from the treatment.are CO2,water and <br /> cell mass. <br /> Pacific Rim has three bioremediation projects underway in Region 5. The projects are under <br /> the jurisdiction CVRWQB'S Fresno office. Reports for these.projects have been directed to two <br /> individuals in the Fresno office. Mr. John Noonan and Mr. Scott Nivens have oversight <br /> responsibilities for these projects. I believe they may be able to give some background on the <br /> bioremediation from a regulator's.perspective. <br /> Our client is interested in proceeding with the remediation of the site. Bioremediation offers a <br /> viable treatment alternative to other treatment technologies. Our hope is that we can resolve <br /> any questions regarding our treatment technology and move forward with the clean up of the <br /> site immediately. <br /> Sincerely, <br /> PACIFIC RIM ENVIRONMENTAL <br /> Michael B.
