Pollution Prevention

	Time Critical Removal Action, Dioxin Contaminated Soil AmDyne performed a Time Critical Removal Action (RA) of burned soil material contaminated with polychlorinated dibenzo-p-dioxins (dioxins) located at the Letterkenny Army Depot (LEAD). A total of 415 tons was excavated and disposed of as part of this effort. After excavation, the waste soil material was immediately loaded into tandem-axle dump trucks and transported to a state-approved landfill. All waste material was disposed of as Residual Waste according to PADEP regulations. Confirmatory samples were collected and analyzed by an off-site USACE-approved laboratory for dioxins. The site was then restored back to natural grade and all equipment demobilized.

	Lead Stabilization and Removal Action AmDyne provided full service environmental management to a CERCLA Removal Action at Letterkenny Army Depot. This site was contaminated with lead at concentrations that exceed risk-based standards. The site was used for the storage of solid metal ingots (copper, nickel, and lead ingots). The ingots were not covered and therefore precipitation ran directly from the surface of the ingots to the ground. This task involved performing waste characterization to segregate waste streams for handling and disposal. In addition, this effort involved excavation, transporting and disposal of waste, as well as confirmatory sampling and site restoration. AmDyne proposed an innovative, In-Situ stabilization technique ( Eco-Bond ) to treat lead contaminated soil at hazardous concentrations and rendered the waste non-hazardous, resulting in tremendous disposal cost savings.

	Remedial Action of VOC Contaminated Soil AmDyne provided technical, environmental, engineering, and construction services to the Corps of Engineers, Baltimore District in order to complete a removal action of soils contaminated with Volatile Organic Compounds (VOCs) and restore the site for future construction activities. This project included submittal of all plans, designs, drawings, specifications and procedures for client and regulatory approval prior to starting the work. AmDyne provided overall management to this complex effort, which was completed on a short time frame to accommodate future constructions at this site.

	UST Removal and Replacement, Bolling AFB AmDyne was responsible for securing all required permits to remove and replace (3) 10,000 - gallon steel underground fuel storage tanks and replace with (2) new 10,000 - gallon double-wall fiberglass fuel storage tanks and integrate them into the existing fuel management system. AmDyne provided a complete set of project drawings in AutoCAD and Specifications in the CSI 16-Division format using Specsintact. AmDyne was also required to provide a sheeting/shoring plan, de-watering plan, demolition and removal of existing concrete slab, excavation, disposal and new construction. AmDyne provided on-site Quality Assurance and oversight throughout construction activities including plans and specification development, shop drawing and equipment submittal reviews and construction daily reports. Soil and water samples were taken prior to excavation, backfill and tank closure reporting. Tank and piping leakage tests were made before and after tank placement and final tank precision testing. Blockage and pressure decay test for the vapor recovery were made prior to the dispensers returning to service. Final site restoration included replacing the concrete slab to match the existing reinforced slab, curb and gutter replacement and restoration to disturbed grass areas. AmDyne provided red-lined as-built drawings, tank closure reports and a fuel management system technician for start-up and system operation check

	Removal/Installation of Storage Tanks AmDyne provided technical, environmental, engineering and construction services to the Veteran's Administration in order to assist in the removal and closure of old underground storage tank systems at Quantico National Cemetery and Baltimore National Cemetary. AmDyne handled all permitting and utility clearances, orchestrated the removal of USTs, performed excavation of contaminated soil, oversaw the restoration of all grading and landscaping, installed new ASTs and associated equipment, and performed all required soil sampling, testing and reporting required for site closure in the States of Virginia and Maryland.
