Investigated soil and groundwater impacts resulting from a release of chromated copper arsenic solution in a warehouse. Project involved preparing sampling and analysis plans, health and safety plans (with confined space entry provisions), supervising site cleanup activities, evaluating laboratory test results with appropriate regulatory criteria, recommending disposal options, summarizing the project activities in several reports, and negotiating a groundwater test plan with several DEQ managers.

Project included evaluation of subsurface soil and groundwater impacted with pentachlorophenol, analysis and interpretation of appropriate and applicable environmental regulations, preparation of a Part B permit application, and negotiating cleanup standards and waste disposal options with Oregon DEQ project manager.

 Investigated soil and potential groundwater impacts at a lead-vinyl products manufacturer from releases of airborne dusts. Project included preparing several sampling and analysis plans, coordinating air monitoring and evaluating air containment systems, supervising site investigation and phase 1 cleanup activities, and corresponding with Oregon DEQ environmental cleanup division (ECD) personnel.

Prepared a RCRA Closure Plan including liquid and soil removal procedures, a Sampling and Analysis Plan (SAP), and a Health and Safety Plan. Utilized PCB field kits to minimize laboratory costs, compared laboratory test results with applicable regulatory reference criteria (40 CFR 761), supervised site cleanup activities, and received a “no further action” letter from the USEPA Region 10 PCB coordinator upon project completion.

Work involved investigation of Washington Department of Ecology (WDOE) and USEPA closure requirements, coordination of on-site facility decontamination, confirmation sampling, and facility closure certification.

Investigated soil and groundwater impacts resulting from a release of chromated copper arsenic solution in a warehouse at a chemical distribution facility in northwest Portland, Oregon. Project involved preparing sampling and analysis plans, health and safety plans (with confined space entry provisions), supervising site cleanup activities, evaluating laboratory test results with appropriate regulatory criteria, recommending disposal options, summarizing the project activities in several reports, and negotiating a groundwater test plan with the Oregon DEQ.

Assisted the client in emergency cleanup of fertilizer and pesticide fire debris, investigated waste disposal and treatment options, and worked closely with with DEQ in preparation and implementation of sampling, analysis, and closure plans and reports. Project involvement also included preparation of regulatory classification reports, design and installation of a wastewater treatment system, coordination of site cleanup and decontamination with Chemical Waste Management, Inc., and negotiation of site cleanup standards with DEQ. Also worked with Oregon DEQ and USEPA to exempt on-site wastes from RCRA Land Ban Disposal Restrictions. Other activities included:

• Preparing a fire debris management plan
• Sampling soil and debris contaminated with agricultural chemicals
• Submitting samples with chain-of-custody documentation to a certified lab, interpreting the results, and characterizing the debris for disposal
• Preparing regulatory classification reports
• Identifying waste removal and disposal options
• Designing a wastewater treatment system for pesticide-contaminated liquids using carbon filtration
• Coordinating site cleanup and decontamination with Chemical Waste Management, Inc.
• Preparing a fire debris removal report for the Oregon DEQ

Project included evaluation of drummed hazardous waste solids and liquids including spent solvents, pentachlorophenol, creosote, paint, and acidic solutions; analysis and interpretation of appropriate and applicable environmental regulations; preparation of disposal permits and applications; and identification of cost-effective waste disposal options.

Assisted in the nvestigation soil and groundwater impacts resulting from multiple releases of lead-contaminated sulfuric acid solution at a lead smelting facility in St. Helens, Oregon. Project involved preparing sampling and analysis plans, health and safety plans, supervising site cleanup activities, evaluating laboratory test results with appropriate regulatory criteria, recommending disposal options, summarizing the project activities in several reports, and preparing a risk assessment and RIFS for the Oregon DEQ.

Assisted in coordination of the disposal of several hundred creosote-treated logs at the subject site. Project involved preparing health and safety plans, supervising log disposal activities, evaluating appropriate regulatory criteria for the disposal recommending disposal/resale options, summarizing the project activities in several reports, and working with the Oregon DEQ.
