Remediation Projects

CCI was awarded a Performance-Based Contract (PBC) for environmental restoration services at the U.S. Army Aviation Center at Ft. Rucker. The scope of services included the design and implementation of a 30-acre former landfill cap (SWMU 2d). CCI developed a Corrective Measures Implementation Plan for the Alabama Department of Environmental Management; submitted the NOR permit; prepared a Construction Best Management Practices Plan for the landfill cover and borrow source.

CCI was contracted for the construction of engineered caps over former phosphorus burial areas. The project was divided into multiple Contractual Areas. By dividing the Contractual areas, CDM was able to manage the logistics to multiple work sites requiring the same fill soil and haul roads. Following site preparation, CCI personnel placed fill to bring the surface to cap elevations; placed a clay barrier layer; placed vegetative soil cover; re-vegetated disturbed areas; performed installation and maintenance of soil and erosion re-vegetated surfaces; and provided surface drainage improvements.

CCI excavated 500 tons of petroleum-contaminated soil at a building to the horizontal and vertical limits delineated by the client. The project included loading of contaminated soils, traffic control measures and backfilling to grade, and achieving the specified compaction standards for the site. CCI excavated and loaded approximately 600 tons of soils from an old service station excavation in the general location.

The project involved TPH and PAH contaminants. Several underground utilities were not marked; therefore, personnel performed surgical excavation of underground utilities.

CCI was the removal action contractor for the Phase I Emergency Removal Action for PCB-impacted soils at the Ward Transformer Superfund project in Raleigh, NC. CCI performed abatement and demolition of several buildings, and excavation, transport and disposal of approximately 400,000 CY of impacted soils, both hazardous and non-hazardous.

Impacted soils reached bedrock in some locations at depths of nearly 30’. The majority of impacted soils were treated to non-hazardous levels using low-temperature thermal desorption and returned to the site, along with imported fill, capped and hydroseeded. The project also included installation, maintenance, and removal of E&SC features including a large stormwater retention basin, extensive stream restoration, onsite water treatment, backfilling, grading and compaction of soils

Below are a few before and after photos of our coal stockpile runoff remediation project. This project also included 6 acres of clearing, grubbing, and grinding trees. CCI finished this project 3 weeks ahead of schedule. CCI excavated, transported, and disposed of approximately 7,350 tons of coal, soil, vegetative debris, and trees that were impacted. 6,000 tons of coal was screened and washed for re-use by our client onsite. CCI also jetted and vacuumed out a 300’ long CMP full of coal and sludge beneath the facility railroad. The construction of drainage swales and E&SC features were completed by CCI. CCI also matted and hydro seeded on this project.
