An effective landfill facility plan will maximize the waste-disposal capacity for the capital cost invested in cell liner construction and provide for efficient day-to-day operations. DBS&A develops plans that describe build-out, including cell layout and timelines. Key issues in developing a plan include:
- Sequencing the tie-in between the older disposal cells for efficient operations throughout the transition
- Regulatory and public implications for final waste height
- Assessing equipment needs for maximum waste compaction
- Financial planning to consider tipping fee inputs, capital construction costs, operating expenses, and financial assurance
DBS&A performs all aspects of permitting associated with solid, hazardous, mixed, and radioactive waste landfills, from the initial siting through operation and closure permitting. In addition to the standard permitting, our projects have involved inventories and reporting needed to comply with U.S. Title V air emission requirements. We have modified existing permits for expansion and efficiency gains and have also performed client support and negotiation services.
DBS&A routinely prepares construction drawings, technical specifications, and bid documents to allow for selection of a qualified contractor for construction. Our landfill engineering designs have gained high marks with regulatory agencies and withstood the tests of construction implementation with contractors. In many states where DBS&A operates, our landfill liner and cover designs include slope stability analysis for the seismic risk at a particular site location. We design stormwater control systems that provide for progressive build-out as cells are developed over the life of the landfill. Our engineers take care to meet all federal, state, and local stormwater design requirements.
