Professional Experience


Chemical Manufacturer (VA) – Successfully negotiated with the regulatory agency to modify a direct wastewater discharge permit to increase the permit limits for metals and toxicity through a mixing zone evaluation, metals translator and toxicity reduction evaluation. Currently negotiating to change the categorical pretreatment standard which would increase the permit limit for solids and BOD. Also undertaking a temperature study to increase the discharge limit for temperature.

Manufacturing Facilities (VA, FL, GA, LA) – Prepared closure and remediation plans at five facilities in four states with PCB and volatile organic contamination. Work with the various state agencies included site investigation, evaluation, remediation, risk assessment, monitored natural attenuation implementation and closure.

Chemical Manufacturer (VA) – Project Manager for RCRA Corrective Action at an industrial facility with 81 SWMUs. Work included investigation, evaluation, and selective remediation under oversight of the Virginia DEQ and EPA. Investigation work included a membrane interface probe investigation and sediment sampling and coring. Contaminants of concern include VOCs, SVOCs, dioxins and furans, and metals. Work also includes tentatively identified compounds (TICs) and developing a successful strategy to minimize the impact of the TICs. In addition to corrective action work, successfully negotiated to modify the existing RCRA Part B permit to close a hazardous waste thermal oxidizer that was taken out of service. Work included planning, observation and certification of closure activities and negotiation of a risk based clean closure.

Cement Manufacturing Facilities (VA, SC) – Provided consulting services for three facilities that store and burn hazardous waste. Each facility has a hazardous waste permit which required RCRA Corrective Action. Directed the investigation, completed data evaluation and risk assessment with state regulatory agencies. Work included the calculation of site specific transfer to groundwater values to limit the groundwater investigation. Also successfully negotiated to limit the number of groundwater wells that required installation. Contaminants of concern include VOCs, SVOC, dioxins and furans, and metals.

Due Diligence Assessments (Various) – Completed Phase I and II environmental assessments for a wide range of facilities. Types of properties varied from commercial, industrial and manufacturing including service stations, retail, hotels, dry cleaners, chemical manufacturing, lens manufacturing, foundries, etc. Scope of services have included auditing of manufacturing facilities to render an opinion on environmental compliance.

Former Chemical Plant (NC) – Lead the investigation and regulatory negotiation for a chemical facility that historically injected treated wastewater into the deep aquifer. The scope of work was negotiated from having to install a completely new monitoring network, to investigating the existing well network using innovative oil field applications and installing only two shallower wells. The work was successful in having the regulatory agency accept a monitored natural attenuation remedy as well as minimizing monitoring to a subset of the network every other year. Contaminants of concern include VOCs as well as a number of site specific chemical intermediate compounds.

Pesticide Spill (FL) – Responsible for the overall project direction and regulatory negotiation of a pesticide spill in a remote location. Project had been underway for 10 years with no progress toward regulatory closure. Obtained regulatory acceptance to eliminate sample locations within the plume and accept the concept of a risk based closure.

Former Chemical Plant (NC) – Lead the regulatory negotiation to move a former industrial landfill out of the Registered Environmental Consultant program. This has allowed to client to have the waste remain in place thus saving millions of dollars. The current remedy is to monitor the groundwater to ensure that monitored natural attenuation is successful.

NPL Site (SC) – Responsible for the design phase services for a 240-gpm groundwater recovery and treatment system for a NPL site with VOC contamination. Work included system design plans, specifications, remedial action work plan, contingency plan, and construction quality assurance plan. Groundwater collection was from seven wells, treatment with a low profile air stripper, an 8000-lb liquid phase carbon bed and treated water reinjection.

Xylene Terminal (NC) – Evaluated historical xylene spill and negotiated with NCDENR and current property owner to accept a monitored natural attenuation remedy. A membrane interface probe was utilized in the investigation to confirm that there were no additional source areas on the subject property.
