PROJECT EXPERIENCE
CTC Services, Inc. – DC-3 Cargo Plane Crash Site Assessment
After a DC-3 Cargo Plane crashed into a residential neighborhood, Source Removal and Site Assessment were required to address soil and groundwater impacts from an estimated 480-gallon discharge of aviation gas. Soil samples were collected for laboratory analysis prior to Source Removal due to the large volume of foam applied by the Ft. Lauderdale Fire Department to extinguish the plane fire. Elevated levels of volatiles detected by use of an Organic Vapor Analyzer (OVA) in the field were attributed to chemical properties of the foam. This discovery at the onset of the assessment minimized soil excavation and disposal resulting in significant savings for the plane owner’s insurance company. Ultimately, Broward County EPD granted a “No Further Action” status for this incident.
BECHTEL–Waste Management at Jacksonville NAS
Supervised installion of a filter-point concrete drainage system in a drainage ditch surrounding a landfill at the Jacksonville Naval Air Station. The drainage system was installed to control erosion and to contain runoff of contaminants.
US SUGAR/South Central Florida Express (SCFE) – Train Track Remediation – Source Removal/Site Assessment Report
In response to a FDEP hazardous waste compliance inspection conducted in 2009, the SCFE retained AM Environmental, LLC (AM) to supervise excavation activity and prepare a Site Assessment Report (SAR). Based on the inspection, used oil staining was observed on ballast rock between railroad ties and soil adjacent to the tracks on both sides of the Maintenance Shop.
Over 1700 tons of used oil impacted ballast rock and soil was excavated after removal of 575 feet of railroad track. In addition, 200 gallons of diesel impacted groundwater was vacuumed from a pit that was left open to aerate for one month. Subsequent to remedial efforts and backfilling with clean fill, an upgraded drip pan system and larger capacity in-ground oil/water separator was installed to limit the potential for future discharges. A No Further Action status without conditions was approved for the SAR Addendum 7 months after initiating this project.
Cooperative Feeding Program – Alternative Procedure Plan for Remediation via groundwater/vapor extraction.
AM devised an Alternative Procedure Plan (APP) to address slightly elevated levels of dissolved volatile organic aromatics (VOAs) and polynuclear aromatic hydrocarbons (PAHS) in the groundwater at a former gas station site. The APP was developed as an exception to Rule 62-770.700 FAC to submit a Remedial Action Plan for active remediation. Groundwater extracted from existing monitor wells from a vacuum truck was proposed to aid in recovering vapors from the smear zone and skimming dissolved hydrocarbons from the surface of the water table.
The purpose of the APP was to impede migration of the existing groundwater plume. The goal was to reduce contaminant levels in the surficial aquifer to Natural Attenuation Monitoring Levels. The APP was implemented to expedite remedial efforts at the site and provide a cost effective solution for this privately funded cleanup by a non-profit organization. The APP was approved by the FDEP and the site is currently being monitored on a quarterly basis for Natural Attenuation Monitoring.
NORTRAX EQUIPMENT COMPANY – AST Installation
Design, permit and install aboveground storage tank farm consisting of seven 500-gallon tanks at heavy equipment sales and maintenance facility. The tank farm is equipped with air lines for dispensing lubricants from diaphram pumps atop ASTs. Flush mounted flood lights with solar sensors provide security by illuminating tank farm and equipment yard. Install complies with applicable Miami-Dade County codes including flood stage elevation survey and fire requirements.
COVE RESTAURANT & MARINA – Marina Dredge/Fill Permit
AM conducted sediment and water quality sampling to obtain a Standard General Permit to reconfigure/dredge a commercial marina. Field sampling was performed in accordance with procedures outlined in the Deepwater Ports Maintenance Dredging and Disposal Manual, FDEP. Due to unacceptable levels of arsenic detected in marina dredge sediments, stockpiled soils were analyzed by a Standard Elutriate Test Method to find a cost effective solution for disposal. Based on this analysis Broward County approved disposal of dredge sediments as a non-hazardous waste at a local Class I Landfill, effectively saving the client thousands of dollars in disposal costs.
MARTIN COUNTY TROPICAL FARMS WWTP – Chlorine 62-780 Site Assessment
Acting as a liaison between Martin County and the Florida Department of Environmental Protection (FDEP) Southeast District, a scope of work was negotiated with the FDEP Southeast District for assessment of an 800-gallon discharge of liquid chlorine from a damaged underground conduit. Impacted soil was excavated and stockpiled on site in a bermed containment area. The impacted soil was left open to vent to the atmosphere. Subsequent testing of the open stockpile indicated nominal chlorine concentrations. The FDEP approved spreading these soils on the surface in lieu of requiring disposal. A Site Assessment Report was prepared in accordance with Chapter 62-780 FAC resulting in a “No Further Action” status granted by the FDEP.
CLIFF BERRY, INC. – UST Abandonment
AM supervised tank cleaning and prepared buoyancy calculations for abandonment of three 4,000-gallon and one 3,000-gallon UST that were filled with an inert light weight foam material approved by the FDEP. This innovative approach offers a viable option to the conventional method of abandoning tanks by filling with concrete in the event that future construction will require removal.
