NEDT™ has completed construction of, and has moved into its new corporate headquarters and fleet operations/dispatch center in Sutton, MA. The new 18,000 square foot building, which replaces leased space, is situated on 6.5 acres and provides the space to accommodate the company’s existing staff and equipment while allowing for expansion as NEDT™ grows.
At the request of the Massachusetts Department of Environmental Protection NEDT™ responded to the site of a small plane crash in Gardner, MA. The plane, which crashed into a swampy area overgrown with brush on its approach to Gardner Municipal Airport, had leaked aviation gasoline from its ruptured fuel tanks. NEDT™ provided personnel, equipment, and materials to clean floating product from the surface of the swamp and removed the remaining fuel for the planes tanks to prevent additional adverse impact to the environment.
NEDT™ provided transportation services to ship 1,800 tons of Polychlorinated Biphenyl (PCB) impacted soil from a Brownfield development site in Southeastern Massachusetts to permitted disposal. Soils classified as TSCA (Toxic Substance Control Act) waste by EPA regulation was transported to a TSCA disposal facility in Western New York State. Impacted soil classified as non-TSCA waste was shipped to a permitted disposal facility in New Hampshire.
NEDT™ was contacted by a Central Massachusetts construction contractor to provide emergency spill response services at a residential development site. The contractor had parked its heavy equipment over the winter months at the site in anticipation of restarting work at the first thaw. At some point in time while it was parked, the fuel line of an excavator became disconnected from the fuel tank and 50 to 100 gallons of diesel fuel leaked onto the ground. To complicate matters the ground surface was starting to thaw and was covered with mud and standing water.
NEDT™ removed impacted standing water and scraped the frozen ground to remove approximately 700 tons of impacted soil and mud. Once the petroleum impacted soil and mud was containerized it was stabilized sufficiently to make it acceptable for beneficial reuse at a local asphalt batching facility. Care was taken during scraping activities not to break the frozen surface as it was believed to provide a barrier between the spilled petroleum and groundwater. Before beginning the removal activities NEDT™ installed groundwater controls to prevent the potential spread of contaminants.
After completing the removal of impacted materials NEDT™ installed monitoring wells to gather groundwater data that would allow it to close the Release Tracking Notification (RTN) with the Massachusetts Department of Environmental Protection. NEDT™ provided Licensed Site Professional (LSP) Services to prepare the documents necessary to complete the release close out process.
At a Brownfield redevelopment site in Boston, Massachusetts NEDT™ provided transportation and disposal services for 1,500 tons of RCRA hazardous Perchlorethylene impacted soil. Working for a construction contractor, NEDT™ prepared hazardous waste profiles for the generator’s signature and obtained disposal authorization from the disposal facility. NEDT™ prepared all shipping documents, including hazardous waste manifests and land disposal restriction forms, for the generator’s signature and transported the impacted soil to a fully permitted treatment and disposal facility in Canada.
A national paint and coatings manufacturer hired NEDT™ to provide industrial maintenance services at its manufacturing facility in eastern Massachusetts. In order to avoid cross contamination that would damage the color quality of its products, residual solids needed to be removed for manufacturing processing equipment. NEDT™’s work included: removing hard dried residual paint solids from the inside of large open topped paint blending tanks; cleaning coagulated solvent based paint solids from the interior of product storage tanks; and removing built up paint solids from the interior of solvent reuse tanks.
To remove the dried residuals in the blending tanks NEDT™ used a combination of air driven scraping tools and hand chippers. The work was complicated by the fact that the blending tanks were polymer coated and care had to be taken not to chip of the coating while removing the solids. Work in the other tanks was completed using non-sparking brass tools because of the high flammable solvent content of the paint. Due to the configuration of the tanks all tank were considered confined spaces and all work was performed using the proper personnel protective equipment (PPE) and under NEDT™’s strict health and safety policies and procedures.
A national hazardous waste disposal firm hired NEDT™ to provide transportation support for a remediation project in Northern New Jersey. Due to the long and involved hazardous waste transporter permitting process in the State of New Jersey, this firm had made a decision not to obtain NJ permits for its own vehicles.
The project required that 250 roll-off containers (approximately 7,000 tons) of solvent impacted soil be transported from the remediation site to a railroad loading facility for continued transport to the final disposal site. NEDT™ provided two trucks and operators for the project and took responsibility for licensing the disposal firm’s intermodal containers under NEDT™’s transporter’s permit.
NEDT™ was able to move 40 to 50 containers a week from the remediation site to the railroad yard and meet the yard’s capacity to manage full containers. Empty containers were returned from the yard to the remediation site for loading by the client. NEDT™ completed the work and has since been hired by the customer for similar projects.
NEDT™ provided transportation and disposal services for approximately 3,300 tons of alum sludge generated by a drinking water treatment facility in Northeastern Massachusetts. Approximately two thirds of the water treatment residuals were transported to a composting facility for beneficial reuse. When this facility reached its daily capacity to receive the waste, the alum solids were redirected to another disposal facility to avoid project delays. NEDT™ also provided waste profiling services and completed shipping documents as part of its services.
An engineering and consulting firm with offices throughout the Eastern United States hired NEDT™ to provide characterization, excavation, transportation, and disposal services for a remediation project in Southeastern Massachusetts. The project site, owned by a Massachusetts state agency, had been vacant for a number of years. Due to its remote location it became contaminated with lead due to illegal dumping activities. When a fire at a vacant building adjacent to the property brought the situation to the attention of local and state regulators the owner was required to remove the surficial debris and subsurface contamination. Delays completing other phases of the project forced the subsurface remediation portion of the project to be completed quickly so that the state agency could meet its reporting requirements to the Massachusetts DEP.
Using information prepared by the engineer, NEDT™ excavated two areas of contamination and stockpiled the impacted material on-site for waste disposal characterization sampling and analysis. NEDT™ personnel collected representative samples of the soil and submitted them to a certified laboratory for rush characterization analysis. After receiving the analytical data from the laboratory NEDT™ prepared waste disposal characterization forms for signature by the generator and submitted them for approval. NEDT™ received approval within three days and remobilized equipment to the site to load the contaminated soil into NEDT™ dump trailers for transportation to a disposal facility in Canada.
NEDT™ was hired to clean an adhesive filled transport tanker located in Southeastern New Hampshire that had been used for years to store “off-spec” batches of process material. Over time the adhesive had solidified and could not be pumped from the tanker. Further complicating the project was the fact that the transport tanker had deteriorated and was no longer considered “road worthy.”
NEDT™ developed a work plan that included using hydraulic shears to cut the tanker open to access and remove the solidified waste material. When removed the waste was drummed for proper disposal by the customer. After the tanker was emptied it was cut into pieces and the metal was cleaned and recycled as scrap.
A regional engineering and consulting firm hired NEDT™ to excavate, transport, and dispose of approximately 150 tons of impacted soil from a location in Boston’s Dorchester section. The project was complicated by the fact that the excavation was located in an alleyway and the tight quarters prevented an excavator from rotating to cast spoils into a truck or container. There was also no space to stockpile removed material beside the excavation. In addition, because the work would take place in a highly congested urban area, removal and backfilling had to be completed quickly to avoid any incidents involving the open excavation.
The NEDT™ used site characterization data to pre-characterize the soil for disposal and obtain disposal approval. Using a combination of excavator and a backhoe loader NEDT™ was able to quickly remove the impacted material and “live load” it into dump trucks for shipment to a disposal facility for beneficial reuse. The excavation was then backfilled and compacted to meet the specification of the engineer. NEDT™ services included the preparation of waste profile forms and shipping documents for signature by the generator.
A Connecticut municipality recently awarded NEDT™ a project involving the transportation and disposal of approximately 1,500 tons of catch basin cleaning solids impacted with Total Petroleum Hydrocarbons (TPH.) NEDT™ will provide transportation to and disposal at a beneficial reuse facility and will prepare all of the paperwork required for disposal approval and transportation. NEDT™ expects to start and complete this project in August 2007.
A Pennsylvania environmental contractor has selected NEDT™ to provide transportation and disposal services at a remediation project in Southeastern Connecticut. The work, which will involve transporting approximately 1,500 tons of soil impacted with TPH, lead, and Poly Aromatic Hydrocarbons (PAH) to an approved disposal facility for beneficial reuse. NEDT™ expects to start and complete this project in late July/early August of this year.
