NEDT™ has begun construction on a new offices and operations center. The 18,000 square foot company owned building, located on 6.5 acres in Sutton, MA, is expected to be available for occupancy in June of 2007. The new building will replace space presently leased by NEDT™ and will house our corporate headquarters and fleet operations and dispatch center. The new building provides the additional space necessary to accommodate the company’s current personnel and equipment while offering the space flexibility needed for future growth plans.
NEDT™ received a Hazardous and Solid Waste Transporters License from the State of New Jersey and a Certificate of Approval to transport hazardous waste in the Province of Ontario, CN. Receipt of the New Jersey license culminated an arduous one-year permitting process that included preparing an extremely detailed and thorough permit application and passing an in-depth review by the New Jersey State Police.
NEDT™was selected by Lightolier-Wilmington as the recipient of its “Commitment to Service Award” for 2006. The award is given annually to vendor that provides the highest customer service as shown by the time energy and dedication it provides to the company.
NEDT™ was selected by a developer to provide environmental remediation services associated with the removal of hazardous wastes and non-hazardous wastes from a former leather tanning oil facility in Salem, MA. This project, expected to take four to six weeks to complete, will include: sampling, analysis, and waste characterization of drummed and bulk wastes; repackaging, transportation, and disposal of over 500 drums of various waste streams; cleaning of acid, caustic, fuel oil, and non-petroleum oil tanks and containers; and lab packing small quantity chemical containers from the facilities, wastewater treatment, research and development, and quality control laboratories.
A national solid waste transportation and disposal firm selected NEDT™ to provide remediation services to clean a water retention pond in western Massachusetts that was impacted by a sudden release of oil. NEDT™ will transfer standing water from the pond into a fractionation tank to separate any standing oil and solids and then pump the water the facility’s discharge point. Due to the pond’s location and difficult access we will use an excavator equipped with a “long stick” to remove impacted material from the bottom and sides of the pond. Once the impacted material is removed, we will load it into NEDT™ trucks and roll-off containers and transport it to a permitted petroleum impacted soil-recycling facility. After removing all of the impacted materials and performing the appropriate confirmation sampling the bottom and sides of the retention pond will be re-covered with stone and rip rap.
Due to heavy rains, gasoline that had been released from leaks in lines and tanks at a gasoline station in western Massachusetts began to show up in an outfall to a small river. The responsible party’s consultant contacted NEDT™ to help contain this release. Soon after the release was discovered investigators found gasoline odors could be found in an apartment building between the gasoline station and the river and had the building evacuated. NEDT™ entered the basement of the building and found that the building also had a sub-basement that now contained six to twelve inches of free product gasoline. It was also discovered that, due to broken piping, untreated sewage waste had collected in the subbasement in the past. Because of difficult access, the sewage waste had been covered with fill rather then being removed. NEDT™ installed explosion proof blowers to vent the gasoline fumes from the structure.
Working in supplied air breathing apparatus NEDT™ pumped the free liquid from the sub-basement. After removing the pooled free liquid NEDT™ personnel dug a sump on the up gradient side of the basement to control the inflow of gasoline and water to the basement. An explosion proof pump was installed and plumbed to NEDT’s 10,000-gallon portable frac tank. Over the course of the project NEDT would remove, transport, and dispose of 5,000 – 10,000 gallons of gasoline and water per week.
Once the inflow was controlled NEDT™ began to manually dig the gasoline contaminated soil & sewage mix from the basement. This process was completed by hand digging the material into buckets that were dumped onto a conveyor system which transported the contaminated material to an NEDT™ roll-off container staged outside the house. This manual interior excavation was completed in Level B personal protection equipment with supplied breathing air. Approximately 45 tons of waste materials were removed from the sub-basement.
After removing the contaminated material NEDT™ installed a sub-slab vapor extraction system designed by the consultant. After installing the venting system a concrete slab was poured over the entire sub-basement floor.
NEDT™ provided transportation and disposal services at an EPA Emergency Removal Action at the former Lonsdale Bleachery complex in Rhode Island. Working for the EPA’s contractor, we provided transportation and disposal of over 3,000 tons of petroleum-impacted soil. As part of its service, NEDT™ prepared all of the required shipping documents necessary to transport 120 truckloads of impacted material to a permitted petroleum impacted soil recycling facility.
NEDT™ completed two additional Lead (Pb) treatment and disposal projects in summer/fall of this year. The first project located at a paper company in western Massachusetts involved the in-situ treatment, excavation, transportation, and disposal approximately 1,375 tons of soil. The second project was the treatment of approximately 1,450 tons of stockpiled soil at a Brownfield site in Boston. In both cases, RCRA hazardous soils were de-characterized using a liquid treatment process and the resulting soils were shipped to non-RCRA disposal facilities. The de-charaterization process provided the clients with reduced transportation and disposal costs as well as eliminating state hazardous waste fees.
We have been hired by an insurance claims management firm to remediate a home heating oil release in Hudson, MA. The project requires that NEDT™ develop a structural shoring plan to support the dwelling while removing petroleum-impacted soil from around and below the structures foundation.
NEDT™ provided an industrial property owner in Connecticut with the transportation and disposal services required to remove of approximately 2,000 tons of petroleum-impacted soil from the site and dispose of it at a permitted disposal facility.
NEDT™ was hired by a contractor working for a developer to provide transportation services for PCB impacted soil discovered at a redevelopment site in Eastern Massachusetts. We moved approximately 2,000 tons of PCB impacted soil to the final disposal facility using a combination of intermodal rail and dump trailer transportation.
NEDT™ provided loading transportation and disposal services to remove approximately 600 tons of perchlorethylene (PCE) impacted soil from a newly developed residential property in Dorchester, MA. On this project we prepared the disposal characterization paperwork to obtain disposal authorization for the owner’s signature and provided all of the hazardous waste manifesting necessary to transport the RCRA hazardous waste to a permitted disposal facility in Canada.
On January 31, NEDT completed a large lead soil treatment, transportation, and disposal project in Boston, MA. Working for a national environmental engineering and consulting firm, NEDT provided services necessary to perform RCRA de-characterization on over 20,000 tons of lead contaminated soil located at a Brownfield redevelopment site that was formerly used for the manufacture of plumbing supplies.
Work on the project was started in late December and, due to a tight construction schedule proposed for the site, the developer required that the stabilization work be completed quickly in to allow the general contractor to stage equipment and materials in the soil processing area. NEDT treated and provided contaminated soil management services for over 600 truckloads of de-characterized soil over a 5-week period to complete the project 3 ½ weeks ahead of schedule.
The services on this project by NEDT included: site health & safety; project and operations management; on-site soil management; soil treatment; confirmatory analysis; soil loading and contaminated soil transportation and disposal services; preparation of soil disposal approval packages, and preparation and tracking of all shipping documents.
NEDT treated the lead contaminated soil in 250-ton batches using liquid treatment technology. After treatment, each soil batch was sampled and analyzed for TCLP lead to confirm that the treatment process was effective. Results of these confirmatory analysis showed that leachable lead was reduced up to 99.99% in the soil matrix rendering it non-RCRA hazardous and acceptable for transport to and disposal in local Subtitle D land disposal facilities. The lead treatment process proved to be 100% effective and, over the life of the project, no soil required handling as a RCRA hazardous waste. NEDT estimates that by using on-site de-characterization instead of hazardous waste disposal the client saved in excess of $2,000,000 on this project.
As the result of an accidental mercury release in its high school, a school system in western Massachusetts determined that it need to remove various waste and outdated chemicals that had accumulated over the years. Because of its experience and ability to respond quickly to emergency situations NEDT was contacted by the contractor responding to the mercury release and asked to provide emergency lab-pack services at the high school.
To avoid unnecessary lost school days the city needed to complete lab pack work while the school building was closed for the mercury clean up. NEDT immediately sent one of its senior chemists to western Massachusetts to begin the lab-packing process. While packaging the waste chemicals at the high school NEDT was asked to expand its services to include three other schools within the city. By the end of the project NEDT packaged over fifty drums of waste and outdated chemicals and transported them to the appropriate disposal facility.
Working for a national engineering firm, NEDT provided personnel and equipment to excavate, transport, and dispose of approximately 65 tons of contaminated soil from inside a former mill building undergoing rehabilitation and redevelopment in Rhode Island. Because of the location of the contamination all excavation work was completed inside the building and this required that a section of the building wall be removed to allow equipment access. The project was further complicated by the need to excavate immediately adjacent to the exterior foundation and key building support columns.
To complete this project NEDT first saw cut and removed the concrete floor and then performed a tiered excavation using its Caterpillar 302.5 mini excavator. The contaminated soil was transferred to a Bobcat loader that moved the soil to an NEDT watertight roll-off container staged outside the building for temporary storage. Because of space restrictions at the site, during the course of the project NEDT provided a straight roll-off truck to move containers between the work location and the temporary storage area. After the removal was completed and the engineer placed chemical compounds in the excavation to facilitate the oxidation of residual hydrocarbons and NEDT backfilled the excavation to grade.
Based on analysis performed by the engineering firm NEDT identified potential disposal outlets, prepared the appropriate waste profiles and shipping documents, and transported the soil to the disposal facility using its roll-off trailers.
At the end of the project the client lauded NEDT for its ability to respond quickly to project changes and for the quality of the work performed by its personnel.
In response to the waste transportation needs of its clients, in February NEDT continued to add to its substantial fleet of transportation equipment. During the month the company took delivery of an additional 53-foot van trailer to add to its ability to move containerized waste for its client base. With this addition NEDT’s fleet now includes twelve semi-trailers capable of hauling a variety of waste materials. In February NEDT also acquired several additional roll-off container. The company now owns over 60 roll-off containers ranging in size from 20 to 50 cubic yards to meet the needs of its waste disposal clients and the remediation projects it works on.
