• RCRA Corrective Action Program (CAP) experience includes managing the first RCRA CAP and RCRA Facility Investigation, and RCRA Corrective Measures Study in North Carolina, which is being performed at an electric motor manufacturing plant. Mr. Marshall played a key role in the design, installation, start-up, operation and monitoring of immediate response actions at the site (two groundwater extraction systems, two air stripping columns, multiple carbon adsorption systems, and two soil-vapor extraction systems), and the design and implementation of the on-going RCRA Facility Investigation (RFI, ongoing). Additional RCRA CAP experience includes the preparation of an RFI work plan for a lead recycling facility in the mid-west.
• Mr. Marshall is currently managing the design and permitting of interim remedial actions as a component of an on-going RFI at a New Jersey manufacturing facility. Remedial actions include a soil vapor extraction system, a groundwater pump and treat (air stripping) system, and air emissions treatment using carbon adsorption. Environmental permits obtained in conjunction with the remediation include groundwater withdrawal, NPDES, and air emissions control systems.
• On another RCRA CAP project, Mr. Marshall is managing the planning and implementation of an RFI at a printed circuit board manufacturing facility in Missouri. As an Interim Remedial Measure, a pump-and-treat system is being designed and installed to remediate groundwater contaminated with chlorinated hydrocarbons. A similar project, involving the investigation and remediation of groundwater contaminated with chlorinated hydrocarbons, is ongoing for a facility located on the Maryland eastern shore.

CERCLA (Superfund) experience includes management of Remedial Investigations (RIs), Feasibility Studies (Fss) and Remedial Design (RDs). Typical examples include:

• RI/FS, RD and oversight of remedial action implementation at the Fulbright and Sac River landfill sites in Springfield, Missouri.
• RI at the Riverfront Park site, a former landfill in Kansas City, Missouri.
• RI/FS at the Hosier Road Landfill in Suffolk, Virginia. A major component of this project was determining the effects of pesticides which had been disposed at the landfill after a fire at a local pesticide formulating facility.
• RI/FS at the Union Road site, a New York State Superfund Site and former railroad maintenance yard in Erie County, New York.
• FS at the Booth Oil site, a New York State Superfund site and former reprocessing facility in Niagara County, New York.
• FS for the U.S. Steel Superfund site, Elmira Heights, New York.
• FS for the Storonske Cooperage Superfund site, Rensselaer County, New York.
• Remedial action design review and design recommendations for VOC contaminated groundwater pump and treatment system at the Gold Coast Oil Superfund site, Miami, Florida.
• Third-party review of RI/FS, and additional site investigation activities at the Odessa Chromium I site in Odessa, Texas.
• RI/FS for The Washington Post to investigate and remediate contamination from upgradient sources, include a dry cleaning facility and a solvent reclamation facility.
• Third-party review and remedial action recommendations for United Chrome (Oregon), Port Washington Landfill (New York), Salford Quarry (Pennsylvania), Yeoman Creek Landfill (Illinois), Coakley Landfill (New Hampshire), City Industries (Florida), H.U.D. Landfill (Illinois), and Millington Landfill (New Jersey).

Environmental compliance and liability audit experience includes:

• A tungsten carbide ore refining facility in Nevada.
• A hospital, regional cancer center, and medical waste incineration facility in Harrisonburg, Virginia.
• Three rubber and polymer product manufacturing facilities in Virginia and Ohio.
• The Oceana Naval Air Station in Virginia.
• A precision electric motor manufacturing facility in North Carolina.
• Four printed circuit board, computer component, and communications equipment manufacturing facilities in Colorado and Kansas.
• A nuclear fuel rod manufacturing facility in Lynchburg, Virginia.
• A metal wire manufacturing facility in South Boston, Virginia.

Mr. Marshall has performed hazardous waste minimization (HAZMIN) reviews at the following facilities:

• Fort Eustis, Virginia, headquarters of the U.S. Army motor pool.
• Fort McClellan, Alabama, site of the U.S. Army MP training center.
• A tungsten carbide refining facility in Nevada.
• A metal parts manufacturing facility in Bedford, Pennsylvania.

Mr. Marshall is also experienced in the performance of environmental audits addressing regulations promulgated under RCRA, CERCLA, TSCA, CAA, SDWA, CWA and FIFRA. Examples include audits at a tungsten carbide refining facility in Nevada; rubber and silicone products manufacturing facilities in Bedford and Buchanan, Virginia; a nuclear fuel rod manufacturing facility; the Naval Air Station at Oceana, Virginia; and a municipal hospital and regional cancer center.

Mr. Marshall managed the preparation of an environmental report required for renewal of a Nuclear Regulatory Commission license for a DOD contractor. The report addressed generation, treatment and disposal of hazardous and low-level radioactive liquid and solid wastes.

A working knowledge of the New Jersey Environmental Cleanup Responsibility Act (ECRA) has allowed Mr. Marshall to provide assistance to various New Jersey clients involved in real estate transfers. Mr. Marshall has prepared the following ECRA submittals: GIS, SES, Sampling Plans, and Cleanup Plans. Bioremediation of petroleum contaminated soils was successfully implemented at an ECRA site.

Mr. Marshall has been involved in several environmental regulatory development programs for USEPA, including:

• A nationwide investigation of leaking underground storage tanks.
• Household hazardous wastes studies for EPA's Land Disposal Branch in relation to the 1984 Hazardous and Solid Waste Amendments to RCRA.
• Location standards for Subtitle D facilities.

A final area of expertise is the treatment of contaminated wastewater, groundwater and surface water. Mr. Marshall has been responsible for the design, evaluation, installation and operation of numerous treatment systems. Recent examples include:

• Performance of an industrial wastewater characterization study, followed by design modifications to allow compliance with wastewater discharge permit limitations at a tool manufacturing facility.
• Evaluation of treatment technologies for the removal of VOCs, semi-volatile organic compounds, PCBs, and heavy metals as components of feasibility studies at several Superfund sites.
• Design of a system to remove total toxic organics from landfill gas condensate, thereby allowing disposal of the condensate at the local municipal wastewater treatment plant.
• Evaluation of an on-site sanitary wastewater treatment system at a manufacturing facility. Design modifications and improvements included installation of an equalization tank, re-routing of industrial discharges to an industrial wastewater treatment system, and modifications to the pre-treatment silt removal system.
• Design, installation, permitting, and ongoing operation and maintenance of multiple air stripping/carbon adsorption systems for industrial supply and nearby residential wells in conjunction with a RCRA Facility Investigation (RFI) in North Carolina.
• Design, installation, permitting, and ongoing operation and maintenance of a free product removal system and groundwater pump and treat system in response to a release of number 2 fuel oil from a 1.2 million gallon aboveground storage tank at a Navy facility in Virginia. The project also involves bioremediation of petroleum contaminated soil.
• Design, installation, permitting, operation and maintenance of a groundwater pump-and-treat system at a Virginia paint manufacturing facility. The project also included bioremediation of solvent contaminated soils at the facility.

Other relevant project experience includes:

• Design of a mobile waste solvent processing system.
• Several PCB spill assessments and remediations.
• Numerous VOC-contaminated groundwater investigations and remediations.
• Investigation and cleanup recommendations for lead contamination at an indoor firing range.
• Miscellaneous Phase I and Phase II site investigations.
• Sampling, analysis, and technical support of a lawsuit involving the environmental and health effects (humans and animals) of Chlordane use in a private residence.
• Investigation of the presence and potential risk posed by pesticides and herbicides at two yard waste recycling and compost facilities.

Prior to joining SCS in 1985, Mr. Marshall spent three years as a chemical process design engineer with the U.S. Army Chemical Research and Development Center at the Aberdeen Proving Ground, Maryland. Responsibilities included the design of handling, treatment, storage, transportation, and disposal systems for the many hazardous substances used and wastes generated at DOD chemical manufacturing facilities. Much of this work was related to organophosphate chemicals. Such compounds are very similar to many of the pesticides and herbicides which are currently of environmental concern.
