ENVIRONMENTAL REMEDIATION

Fort Lauderdale-Hollywood Airport South Terminal Environmental Remediation

The South Terminal (Terminal 4) site was historically used as a fuel storage facility, and underground storage tanks were removed in 1975. CEI participated in active site remediation that began in 2012 as a sub to HDR Engineering (HDR). The site was divided, and CEI completed remediation in three phases, each consisting of source removal of soil and free-floating product (FFP) and air sparging of the groundwater. In 2017, a Memorandum of Agreement (MOA) was executed and recorded between Broward County and the Florida Department of Environmental Protection, allowing for the site’s conditional closure due to remaining on-site contaminated soils and groundwater. Also in 2017, as a sub to Munilla Construction Management (MCM), CEI performed remediation of petroleum, arsenic, and asbestos-contaminated material from the Terminal 4 Apron area (approx. 7 acres) in an effort to remove all contaminated material to allow expansion of the Apron project. The remediation scope included excavating, stockpiling, testing, and disposing of approximately 21,000 tons of petroleum-contaminated soils off-site and pumping out 35,000 gallons of FFP.

West Cargo Fuel Tender Facility Relocation, Miami
International Airport, Miami, FL

CEI relocated the existing West Cargo Fuel Tender Facility at Miami International Airport (MIA,) which allowed for the extension of Taxiway R to accommodate larger aircrafts. This new facility consisted of a nine (9) bay canopied fuel facility that will be used to load jet fuel into aircraft refueler trucks and to offload and dispense diesel. The project included new filter/separator vessels, pressure surge protection, pressure and flow control valves, piping, and accessories. In addition, the project included New Fire Protection and Fire Alarm System include controls and, a new Fuel Management System.

As part of the environmental remediation scope of work, CEI designed, implemented and operated a complete dewatering system treating over 5-million gallons of hydrocarbon and vinyl chloride contaminated groundwater. CEI applied for and obtained the dewatering permit, and provided required system sampling and reporting per the permit as part of the installation of the Hydrant Fuel System. Additionally, CEI demolished the former control building, and excavated, removed and hauled off-site over 8,000 tons of hydro carbon contaminated soils.

Miami International Airport, Taxiway R, S & T Miami, FL

CEI was contracted by General Asphalt Corp (GAC) as part of Miami Taxiway R Rehabilitation Project to handle all environmental related work.

As part of the environmental remediation scope of work, CEI prepared the Soil Management Plan (SMP) to provide procedures to manage soils generated during construction related to the Miami International Airport (MIA) Taxiway R,S and T Rehabilitation, Extension and Relocation project. CEI temporarily stockpiled suspected soils with berming/lining, coordinated confirmation sampling, hauled, and disposed offsite over 38,000 tons of hydro carbon contaminated soils. The value of the environmental work was over $5.5M. Additionally, CEI removed an abandoned Underground Storage Tank (UST), removed out of service underground Jet-A Fuel lines, decommissioned the former control building, and installed large underground Oil/Water Separators (OWS) ranging from 10,000 gallons to 20,000 gallons in capacity.

Fort Lauderdale-Hollywood International Airport, Trails End Remediation, Dania Beach, Florida

As part of Terminal 4 Expansion at the Fort Lauderdale- Hollywood International Airport (FLL), CEI provided emergency response to Broward County Aviation Department (BCAD) at the Trails End site for the removal, haul, and disposal of approximately 50,000 Cubic Yards of Asbestos Contaminated Soil.

CEI loaded between 1,200 and 1,700 tons per day, working 10 to 12 hours per day for seven (7) days a week. In total, CEI removed and disposed offsite over 70,000 tons of asbestos contaminated soil, with a contract value over $3.8M.

Once the asbestos contaminated soil was removed, CEI provided Bermuda Hydro-Seed over most of the Trails End Site.

Miami International Airport Hazardous Material Removal Contract, Miami, FL

CEI was awarded a Hazardous Material Removal and quick response contract for MDAD airports to perform asbestos abatement, air quality remediation including mold abatement; contamination soil removal, transportation and disposal; installation of storage tanks; PCB transformer removal; lead paint removal; all petroleum hazardous material handling; and removal of abatement of anything that is or may be considered an environmental hazard.

At MIA Concourse BC, environmental remediation of hydrocarbon impacted soil was performed, and sewer lines were installed. At MIA Terminal E, CEI completed abatement of asbestos containing floor mastic in the HVAC mechanical room and the equipment storage area. At MIA, Milam Diary Drive and 12th Street, CEI handled the loading, transportation and disposal of contaminated crushed concrete. At MIA Taxiway K, drainage and dredging with transportation and disposal of contaminated soil was performed.

AT MIA, UPS Building 807, 385 CY of contaminated soil was remediated and disposed of at a licensed waste disposal facility (CEMEX). Finally, at MIA, MDAD Building 881 & 883, CEI completed asbestos abatement and closure reporting of 2 unoccupied buildings.

Miami International Airport Emergency Response, Miami, FL

CEI responded to the fire at Miami International Airport’s Fueling Facility. CEI was tasked by MDAD and Allied to conduct the emergency response cleanup activities and restore the fueling operation by working closely with other key contractors. The company was designated by OSHA and MDAD to serve as the Health and Safety On-Scene Commander with OSHA and provide remediation and cleanup services.

As part of the Environmental Remediation Scope of Work CEI conducted excavation activities for installation of a new underground double-walled fuel lines, ranging from 12-inch to 30-inch in diameter. CEI also performed the remediation of contaminated soils and groundwater by removing the fuel-saturated soil (approximately 21,000 tons) for off-site disposal and skimming of free-floating product.

Also, as part of the scope, the company designed, set-up, and conducted dewatering system for installation of the underground fuel piping system.

Curtis Park Environmental Remediation, Miami, Florida

CEI completed a $4.6M Curtis Park Environmental Remediation project for the City of Miami. The work consisted of corrective actions to address contamination at the City of Miami owned and operated 25 acre property called Curtis Park. The work area for this project is approximately 12 acres. CEI implemented procedures for selective removal and replacement of structures and other park features and foundations, including removal of on-site fencing, sand pit, selected asphalt walkways, bleacher pads, and a one story concrete building and pad.

CEI also excavated an approximately 12” layer of surface soil and ash from specified areas of the park, and relocated excavated material on-site to the baseball field area, where it was used to re-grade the area prior to adding a geosynthetic clay liner, and clean fill cap. The excess excavated material was hauled off-site and disposed of at a Class I Landfill, more than a dozen drainage wells (Class V Wells) and associated piping and catch basins were installed for management of stormwater.

The improvement provides a much safer park for the community and a cleaner atmosphere for the residents. The scope of work involved Design/Build and Construction Management including the removal of up to a foot of topsoil, installing a waterproof sheet liner and then refilling the area with clean soil. In addition to the remediation of the site, the drainage system was rebuilt to include six new gravity wells, a new irrigation system for the ball field, the parking lot was repaved, a walkway was added and new lights overseeing the walkways and parking lots were also added.
