Sustainable Solutions / Beneficial Reuse

Challenge:

• Client needed to closeout two API separator ponds
• Fuel terminal was located in tropical rainforest
• Off-site disposal of sediments were cost prohibitive

Results:

• Completed feasibility study to develop optimal sediment mix design for recycling purposes
• Redesigned on-site stormwater/erosion control system to allow for remedial efforts to occur during inclement conditions
• Utilized other impacted materials on-site such as HC impacted berm soils, and dredge spoils for a stormwater canal as feed material in mix design
• Excavated 22,000 cubic yards of oily sediment from former stormwater ponds
• Pond sediment, imported blending soils and a reagent admixture was processed in LWR’s cold mix pugmill plant
• Produced a total of approximately 38,000 tons of beneficial reuse product
• Provided full-time CQC and CQA services

Benefits:                 

• Recycled waste was used for on-site construction purposes
• Client saved over $2 million in off-site remediation and over $800,000 in construction material costs
• Expanded available site construction area air space by 55 acres
