Project Descriptions for Bois Consulting's Principal-in-Charge | | | | Bois Consulting Company, Inc. specializes in management of hazardous waste site projects, environmental regulatory assistance, agency/private party negotiation, third-party review, due diligence services for acquisitions and divestitures, and Licensed Site Professional (LSP) services at Massachusetts (MCP) sites. She has managed projects at RCRA Corrective Action Sites, Superfund Sites, and state-regulated sites nationwide. Below are examples of representative projects underway or completed by Ms. Carol de Groot Bois, President. | MCP Sites/LSP Services | Confidential Client – Bellingham, MA Waiver Site; Tier II; RAM Completion Chemical Oxidation of Kerosene Release | LSP-of-Record DEP, Central Region | Ms. Bois is the LSP-of-Record for a site in Central Massachusetts where a release of 23,000 gallons of kerosene occurred in 1992. Other consultants had implemented several remediation techniques, which reduced the mass of petroleum in soil and groundwater but did not achieve the site-specific cleanup goals for the client. Ms. Bois assisted the client in meeting the Interim Deadlines set by the agency for a Phase III feasibility study of remedial alternatives, and a Phase IV design and implementation report for the remediation system. Currently, chemical oxidation using potassium permanganate is being used to treat the residual petroleum in the soil and groundwater. | BASF Corporation - Holyoke, MA Site Investigation, Feasibility Study Facility Decommissioning Steam Injection/Air Sparging/SVE - Styrene/VOCs | LSP-of-Record DEP, Western Region | Ms. Bois provided regulatory interpretation and research for negotiations between the client and the former site owner to reach a settlement for a 5-acre site. This former manufacturing facility had LNAPL (primarily styrene) contamination of soil and groundwater. In addition, Ms. Bois was the LSP-of-Record for the removal of ten underground storage tanks during their decommissioning and a month-long field investigation using an on-site mobile laboratory to determine the locations of soil borings and monitoring wells. She also is the LSP for the risk characterization and feasibility study, which examined remediation alternatives for the VOC contamination of the soil and groundwater. The remediation option selected, which is currently underway at this site, is air sparging with steam injection and a vapor recovery system. | Confidential Client - Billerica, MA Class C RAO, AUL, Monitoring, 5-Year Periodic Evaluation Drum Disposal | LSP-of-Record DEP, Northeast Region | Ms. Bois has been the LSP-of-Record for the past eight years at this site in Billerica, MA, and has managed this project since 1989. This site consists of a drum disposal area disposed on-site over 30 years ago. Ms. Bois successfully convinced the DEP to allow the drums to remain in place with a program of routine monitoring. The site was closed in 1994 with an Activity and Use Limitation (deed restriction). Ms. Bois coordinates a semi-annual monitoring program at the facility. Initially, the agency also required a statistical analysis of the data required by the agency. The monitoring information is compiled in a report and submitted to the agency on a regular basis as part of the MCP closure requirements. | Fuel Oil Release - Needham, MA Immediate Response Action, Site Closure (RAO) Fuel Oil, Excavation & Off-site Recycling | LSP-of-Record DEP, Northeast Region | An estimated 100 gallons of fuel oil leaked from a faulty fuel line at a residential property in Needham, MA. As the LSP for this project, Ms. Bois oversaw an initial field investigation to determine the extent of contamination in the soil and groundwater. Using cost-effective direct-push soil borings, six small-diameter groundwater monitoring wells were installed; soil samples collected; and over 4 inches of LNAPL measured in one well. On behalf of the client, Ms. Bois notified the DEP and received approval for an Immediate Response Action (IRA) consisting of soil excavation and disposal, and groundwater dewatering and treatment/disposal. Groundwater contamination was encountered during the excavation activities, and bedrock wells were installed to determine groundwater quality. Following remediation, the property was sold and re-developed with new residential construction. The site was closed within one year of discovering the contamination. | New England Emulsion Corp. - Holliston, MA Spill Response, Asphalt Emulsion | LSP-of-Record DEP, Central Region | New England Emulsion had a release of approximately 50 gallons of an asphalt emulsion mixture from an aboveground storage tank. This release was handled as an Immediate Response Action and approximately 8,000 gallons of a rainwater/asphalt emulsion mixture was reused in the process on-site, with contaminated soil from the site recycled at an asphalt batching facility. This release was closed within 60 days of initial response, thereby allowing the client to eliminate additional fees from the state. | Confidential Client - Holliston, MA Spill Response Fuel Oil | (Less than RQ) | Avery Dennison contacted Ms. Bois upon determining that motor oil had been released to an unpaved parking area at a warehouse facility. Although the release was less than a reportable quantity, the company wanted to perform sampling and remediation activities to accurately document the response actions taken by the facility. Ms. Bois performed confirmation soil sampling, assisted in determining disposal/reuse options for the contaminated soil, and completed a report documenting the spill response activities and compliance with state performance standards for cleanup. | The Beacon Group - Wakefield, MA Site Investigation, Risk Characterization, Feasibility Study& Site Closure Lead-Contaminated Soil, Capping and Culverting | LSP-of-Record DEP, Northeast Region | Ms. Bois designed and implemented a site investigation program and oversaw remediation of a property that was formerly owned by a lead pipe manufacturer. The site contained elevated levels of lead in the surface and subsurface soil as well as in sediment from an on-site stream. Using a track-mounted Geoprobe™ unit, vertical profiling of the soil was completed in order to delineate the lateral and vertical extent of lead in the soil. This information was then evaluated in a human health/environmental risk assessment, which indicated direct contact with the soil would pose a significant risk as defined by the Massachusetts regulations. Remediation options were evaluated in a feasibility study, and capping was determined to be the most feasible option for this site. The project required significant coordination with the local Conservation Commission and Town Engineering Department under a Notice of Intent due to potential wetlands impacts. As part of a local flood control project, the on-site stream was replaced with a culverted section, necessitating work in contaminated sediments. In addition, an engineered barrier (cap) including a liner was placed on the property. In 2001, this Site was closed with institutional controls (a deed restriction or "Activity and Use Limitation") to restrict certain site activities in order to meet Massachusetts risk-based closure requirements. | Mfg. Company (Confidential) - Western MA Site investigation, Feasibility Study, Site Closure Excavation, Ex Situ Soil Vapor Extraction - VOCs | LSP-of-Record DEP, Western Region | This coated paper manufacturing facility has been operating for over 50 years. The facility had numerous underground storage tank farms for the storage of solvents such as toluene, ethylbenzene, and methanol. Ms. Bois is the LSP for two of the on-site areas that the facility is closing in accordance with the MCP regulations. One area is a former solvent storage tank farm and the other a former #6 fuel oil storage tank area. Ms. Bois oversaw the site investigation work, which consisted of soil, groundwater, surface water, and sediment sampling to determine the vertical and lateral extent of contamination. This information was used to prepare a Feasibility Study, including groundwater modeling to predict future impacts to a nearby stream. The site soils are currently undergoing remediation using an ex situ soil vapor extraction system. | Environmental Policy Development | Confidential Client - Environmental Program Guidelines Corporate Policy Document Development and TrainingMs. Bois was the project manager for development of a comprehensive Corporate Environmental Policy on Release Investigation and Remediation, as part of the company's EHS program. The purpose of the document was to provide an in-depth guidance document for facility personnel worldwide. This document was later revised under Ms. Bois' guidance to incorporate a risk-based approach to site remediation projects. Ms. Bois also participated in a training seminar for corporate and facility EHS personnel regarding implementation of the policy document. Sudbury Valley Trustees - Site Assessment TrainingAs part of pro bono work requested by SVT, Ms. Bois prepared a summary of the ASTM standard Phase 1 Site Assessment work for property transfers. SVT is a non-profit organization that acquires property for preservation of open space and protection of environmentally-sensitive areas. Ms. Bois provided a brief training seminar so that staff and directors of the organization understood the financial and liability implications of contaminated property as well as the requirements for a proper site assessment during the property transfer process. DNAPL Sites A.J. Knott Tool & Manufacturing Company - Milford, MA Site Investigation, Risk Characterization Feasibility Study - Capping, Monitored Natural Attenuation DNAPL/Chlorinated Solvents
Bois Consulting Company provides LSP services, regulatory expertise, site evaluation, and assistance with private party negotiations for this manufacturing company. The company had been notified by the DEP that the site of their former operations had remained listed as a site under the MCP, due to the discovery of chlorinated solvents (PCE and TCE) in the soil and groundwater at the site. The site is located in the Zone II of a public water supply. On behalf of A.J. Knott, Bois Consulting Company used existing information to prepare a Phase I Report, a Tier Classification, and a joint Tier 1 Permit for the two parties. A Phase II Investigation was performed, including soil, groundwater, surface water and sediment sampling, to delineate the nature and extent of VOC in the soil and groundwater at the site. A Human Health/Environmental Risk Assessment, Phase III Feasibility Study, and Phase IV Implementation Plan (Design Specifications and Construction details) were completed. A Monitored Natural Attenuation program is being implemented in conjunction with capping of contaminated soil. Confidential Client - Rhode Island Field Investigation, Conceptual Remedial Design Chlorinated SolventsMs. Bois was the Project Manager for a comprehensive hydrogeologic investigation for a site with both a former industrial landfill and surface impoundments. The hazardous wastes disposed on-site were from electroplating and machine tool manufacturing operations and included metal plating sludges, chlorinated solvents (TCE, PCE), paint sludges, and waste oil. Ms. Bois designed and implemented a field investigation program consisting of groundwater, surface water, soil, and sediment sampling; a geophysical survey; a soil vapor extraction pilot study; and a private residential well survey and sampling program. A conceptual design for hydraulically containing the DNAPL and remediating the dissolved VOC in groundwater was prepared for the client. |
