Project Description

The Blue Ridge Recycling and Disposal Facility is a municipal solid waste landfill located in Central Kentucky.  This site received approximately 1,000 tons of waste per day during the service period.  The landfill is located in a mountainous area and has no natural, on-site soil liner material.  The soil liner material was “manufactured” from shale by crushing, grinding, and screening operations.  The facility has significant water problems due to groundwater and surface water runoff. 

The landfill liner system consists of a verified subgrade, groundwater underdrain, 3 feet of recompacted soil liner, a 60-mil HDPE geomembrane liner, a 16-ounce nonwoven geotextile, and a gravel leachate drainage layer. 
 

Scope of Engineering & Professional Services

CBBEL staff prepared conceptual plans for a 100-acre expansion of the existing landfill.  This project included a site layout and design, soil balance calculations, and preparation of airspace calculations.  The conceptual design included a groundwater drainage system under the composite liner system, leachate management system, surface water runoff design, floor grade design, and final cover design.

CBBEL staff prepared construction drawings for two year’s liner construction.  These drawings provided a detailed summary of the work to be done by the contractor for the project and were used in the contract documents.  Control elevations were provided on a 50-foot grid for each layer of liner to insure compliance with regulations.  Specific details were provided to the contractor to convey the proper construction of tie-in areas, intercell berms, side slope risers, sumps, and leachate collection trenches.  An electronic file was generated for use by the surveyor to verify the accuracy of the liner elevations. 

CBBEL staff also performed full-time construction quality assurance (CQA) services for portions of the composite cell liner system construction.  CBBEL staff coordinated the installation of the soil and geomembrane liners, the leachate collection system, the sump, and the side slope riser installation.  CQA activities included daily inspection, monitoring, sampling/testing, verification of component grades and thicknesses, and documentation of the construction work.  A certified documentation report that contained a project narrative, daily field reports, sampling procedures and locations, testing results, photographs, and as-built drawings was prepared and approved. 

CBBEL staff performed annual airspace calculations using Computer Aided Design (CAD) software.  Waste densities and financial accruals were also prepared.  In addition, various other services were provided for the site, including quarterly plot plans, asbestos location reports, sedimentation basin design, stormwater runoff analysis, and closure/post closure estimates.
