ESMI Job Summary Project Highlights
Site: Former MGP Site in Manchester, NH.
Contaminate: Coal Tar (MGP Waste)
Tons of Material: 11,000 tons.
Project Highlights / Special considerations:
This project involved dredging a section of the Merrimac River in Manchester, New Hampshire that was impacted with historical releases from a manufactured gas plant operation. The soils generated had an average PAH concentration of approximately 4,000 ppm. ESMI of NH worked with the site to insure the material moved efficiently through the dredging, stockpiling and sampling, to the transportation to ESMI of NH. ESMI of NH supported this project by accepting an average of 300 tons per day, insuring that the project moved smoothly due to a limited space available for soil staging. The soils were treated to meet ESMI of NH’s permitted soil reuse criteria and in most cases below the laboratory detection limits for PAH compounds. The treated soils were re-used as commercial fill as defined by the facilities solid waste permit.
Site: EPA Superfund site in Troy, NH.
Contaminate: VOC’s and SVOC’s
Tons of Material: 26,000 tons.
Project Highlights / Special considerations:
This site was a former landfill for a local mill in Troy, New Hampshire. The Troy Mills Landfill site, owned by Troy Mills, Inc., was located about 1.5 miles south of the center of Troy, New Hampshire. It was situated off a dirt road and on the wooded portion of a larger 270-acre parcel of property. The owner used the two-acre Troy Mills Landfill site from 1967 to 1978 as a drum disposal area for an estimated 6,000-10,000 drums of liquid wastes containing petroleum based solvents. ESMI of NH offered a cost effective alternative to land filling the soil on this project. ESMI of NH worked with the environmental cleanup contractor as well as the site’s On-Scene Coordinator to provide a cost effective alternative to land filling the soil. On this project, ESMI of NH provided logistical support for transportation as well as the thermal treatment of the soils. ESMI of NH was able to move up to 700 tons per day from the site, bringing the project in under budget and ahead of schedule. The soils were treated to meet ESMI of NH’s permitted soil reuse criteria and in most cases below the laboratory detection limits. The treated soils were re-used as commercial fill as defined by the facilities solid waste permit.
Site: EPA Superfund site in Baldwinville, Ma.
Contaminate: Low level, non-TSCA PCBs
Tons of Material: 16,000 tons.
Project Highlights / Special considerations:
This project involved the excavation of low level, non-TSCA PCB-contaminated soil from 50 residential properties located near the former Temple Stuart facility, in Baldwinville, Ma. The concentrations of PCB found in the soil were higher than those acceptable for residential properties in Massachusetts. Under the guidance of the EPA, the contractors restored these properties. The work included evaluating each property, removing any off specification material, backfilling the properties with sand and loam, and then hydro seeding the properties. ESMI of NH offered a cost effective alternative to land filling on this project. ESMI of NH was able to provide logistical support for transportation as well as the thermal treatment of the soils. ESMI of NH was able to move up to 700 tons per day from the site, keeping the project under budget and ahead of schedule. The soils were treated to meet ESMI of NH’s permitted soil reuse criteria and in most cases below the laboratory detection limits. The treated soils were re-used as commercial fill as defined by the facilities solid waste permit.
Site: Former MGP Site in Waterbury, CT.
Contaminate: Coal Tar (MGP Waste)
Tons of Material: 24,000 tons.
Project Highlights / Special considerations:
Because of the location and large size of this particular project, the ESMI Companies were able to utilize two of its facilities (NH & NY) to move large volumes of soil daily. The ESMI Companies provided logistical support for transportation as well as the thermal treatment of the soils. The ESMI Companies were able to move up to 800 tons per day from the site, keeping the project under budget and ahead of schedule. The soils were treated to meet both facilities permitted soil reuse criteria and in most cases below the laboratory detection limits. The treated soils were re-used as commercial fill as defined by the facilities solid waste permit.
Site: Loudon Country Club, Loudon, New Hampshire.
Contaminate: N/A, Soil Reuse Site
Tons of Material: ~350,000 tons.
Project Highlights / Special considerations:
One of ESMI of NH’s first re-use projects was the creation of an 18-hole golf course in Loudon, NH. Prior to the creation of the golf course, the land was undeveloped and poorly graded. Through working with ESMI of NH, the developer was able to cost effectively transform this site into one of the more beautiful and challenging courses in the area. Since that time, ESMI of NH has assisted other developers with their commercial property developments. Thermally treated soils have been used for:
- Sand /Gravel pit reclamation
- Several parking lot expansions
- A commercial green house expansion.
