Landfill Closure Design and Permitting

Along with our landfill design and construction services, SCS also understands the long-term requirements to properly close a landfill and use it for beneficial purposes; capping, stormwater control, erosion control, LFG, leachate collection and management, re-vegetation, groundwater monitoring, mitigation of settlement, and environmental compliance. SCS has prepared closure designs for some of the largest closure projects in the world, including the Fresh Kills Landfill in New York City.  SCS has prepared closure designs incorporating innovative final cover designs, use of light-weight fills, retrofitted side slope drainage configurations, leachate management systems, LFG controls, and end use plans. 

SCS also offers clients post-closure care operation and maintenance through SCS Field Services O&M division.  Typical post-closure service areas offered by SCS include the following:

·         Final Cover System Monitoring and Maintenance
·         Surface Water Monitoring and Drainage System Maintenance
·         Gas and Vapor Extraction Systems Operation, Monitoring,
     and Maintenance
·         Groundwater Sampling and Treatment System Operation,
     Monitoring, and Maintenance
·         Odor and Air Emissions Monitoring, Investigations, Modeling
     and Remediation
·         Regulatory Reporting and Compliance Management.

SCS has full, in-house technical capabilities including slope stability modeling (global and veneer), settlement estimates, hydraulic and hydrologic modeling for control of stormwater runoff, water balances and leachate generation estimates, design erosion controls, vegetative cover designs, comparisons of cover design options, constructability reviews and related areas.  As landfills have the potential for end-uses, SCS is a leader in the industry in promoting and designing closures that allow active and passive end-uses that are environmentally safe and cost effective. Successful end use projects completed by SCS have included recreational facilities, resort hotels and conference centers, golf courses, and passive parks.
