As noted in Section Two,which describes our relevant work,we have <br /> successfully completed soil borrow studies and leachate system design. Since leachate from the Eubanks Road <br /> landfill is discharged to the sanitary sewer, leachate management and treatment may be less of an issue for the <br /> OCSWM compared to other facilities; however, maintenance of the collection system and strategies to minimize <br /> leachate generation will help to lower future operational costs. <br /> Landfill Gas Management <br /> Landfill gas management is important not only for regulatory compliance, but also for managing operational <br /> issues such as odor control and minimizing a source of VOCs to leachate and groundwater.As noted in Section <br /> Two: Experience,we have completed Title V permitting and greenhouse gas reporting for several clients. Our <br /> field services personnel have successfully operated and maintained active LFG collection systems.This includes <br /> monitoring gas production and optimizing gas extraction by balancing the system and isolating areas of the <br /> system that require repair as landfills settle. One particular success is at the Henrico County,Virginia,Springfield <br /> Road Landfill where LFG is being extracted to generate electricity.A year ago the system was extracting <br /> approximately 540 scfm from the landfill. During the past year,through trouble-shooting, balancing,and <br /> repairing the extraction system we have optimized the extraction rate and are now pulling 950 scfm with over <br /> 50% methane and less than 0.5%oxygen. <br /> Solid Waste Facility Operations Assistance <br /> Our staff is prepared to assist the OCSWM with operations at the Eubanks Road Facilities. Several of our local <br /> staff are licensed Landfill Operators (MOLO) through SWANA and have a wealth of experience with multiple sites <br /> across North Carolina and other states. Our engineers,field services personnel, construction managers,and <br /> surveyors have decades of experience in the solid waste industry and can provide the input needed to optimize <br /> your operations. Additionally,our network of solid waste clients can put you in touch with other operators who <br /> can also provide insight and assistance. <br /> Transfer Station and Convenience Center Design <br /> With the possibility of OCSWM permitting and constructing a solid waste transfer station in the near future, <br /> DAA is prepared to assist OCSWM with the many steps and components necessary for a successful project. As <br /> you are aware,gaining the support of the public, local residents,and the governing board is a must. We have <br /> successfully assisted our clients with public presentations,data gathering,creation of exhibits, and arguing on <br /> their behalf to help a project gain the support and approvals necessary to move forward. Our in-house design <br /> team includes the expertise necessary to design a solid waste transfer station or a small waste convenience <br /> center for OCSWM. <br /> Draper Aden Associates <br /> Engineema!
