Environmental Remediation

Challenge:

• This Superfund Site was defined by the TCEQ as the “#1 State Superfund Site in Texas”
• The site was formerly occupied by a refinery that operated from 1928 to 1969 on about 183 acres
• Site specific safety and health requirements
• Unseasonably wet construction season
• Loss of local rip rap supply

Results:

• LWR has provided various improvement to the site including installation of a closure turf system for the containment cell
• Repair of existing containment cell surface erosion and surface preparation for closure turf system utilizing cement enhanced soil
• The containment cell contains over 900,000-cubic yards of impacted materials
• The new closure turf system consists of 915,329-square feet of geotextile, geosynthetic membrane and turf with sand in-fill
• Installation of 3,500-linear feet of anchor trenches
• Installation of 1,200-tons of rip rap to armor line the system drainage swale

Benefits:

• Reduction in long-term maintenance costs
• LWR was able to modify work schedule and make the necessary adjustments in order to complete the project with minimal impact
• LWR was able to complete the project with no safety or security incidents
