V. Product Application <br /> The initial application of bioremediation product will be applied at a 10%concentration to the soils within the <br /> open excavation via aspiration nozzle and pump. A total of 500-550 gallons will be utilized during the initial <br /> application from fresh water pumped from the adjacent Yule Creek. Fresh water from Yule Creek is ideal due <br /> to the water already containing the natural elements typical for this area, as well as a great source of <br /> dechlorinated water, preventing mortality of the bioremediation enzymes. <br /> Water and Microblaze product will be mixed together at the appropriate ratios and sprayed into the excavation <br /> during the initial treatment to provide a thorough application prior to backfilling. For subsequent treatment <br /> applications, micro-blaze, nutrients and oxygenating compounds will be gravity fed through the treatment <br /> system. <br /> B. Winter Treatment <br /> Follow-up applications via the infiltration ports will occur monthly throughout the winter months when <br /> conditions allow. Product will be applied at an 8-10% concentration, utilizing water from Yule Creek and <br /> mixed onsite as needed. The amount of bioremediation product applied will vary on timing of the year but <br /> will typically consist of 550-1000 gallons of water to bioremediation product and amendments. <br /> C. Summer Treatment <br /> During the spring/summer months, when temperatures are optimal for bioremediation activity and snow <br /> runoff is occurring, a second treatment will be applied to continue the bioremediation process. Additionally, <br /> based on runoff volumes,a higher quantity may be applied using the runoff water flowing above the previous <br /> creek channel to provide the necessary ratio to activate the microbes and transport the product downgradient. <br /> Summer treatments are going to vary based on hydrocarbon concentrations within the downgradient <br /> monitoring wells and hydrocarbon concentrations within the soil. The amount of treatment product will likely <br /> remain the same, 550-1000 gallons, although concentrations and frequency are going to be dependent on <br /> conditions and contaminant concentrations. <br /> D. Treatment Conditioners <br /> As with all microbial activity,bioremediation products require a food source and oxygen. It will be necessary <br /> to include a periodic treatment of oxygenated water and liquid fertilizers to enhance and keep the microbial <br /> activity optimal <br /> VI. Closure <br /> Closure of the project will be based on the conditions set forth by the regulatory agencies providing oversight. <br /> Upon completion of the bioremediation process, PVC infiltration ports can be filled with sand and/or cut at or <br /> below ground surface and capped. <br /> VII. Conclusion <br /> The information outlined above is designed and intended the enhance the bioremediation of diesel impacted <br /> soils. Please note that changing conditions, site activity,geochemistry and other unforeseen circumstances may <br /> 3 <br />
