Overview:
Mr. Littlejohn has 30 years of professional experience in the environmental and petroleum industries. He specializes in the risk-based characterization and fate & transport modeling of contaminants through the vadose zone soil, and groundwater. He is also experienced in environmental compliance, property transfer, oil field damage assessments, and remediation. He possesses significant experience associated with the assessment of underground storage tank (UST) sites, natural gas gathering, compression, and treatment facilities, and crude oil production, transmissions systems, and refining facilities
Environmental Site Assessments and Audits:
Conducted approximately 35 Phase I assessments of crude oil production facilities, pipeline facilities (including booster stations and tank farms), and oil fields. The properties range in size from 2 wells and a tank battery to a 500 well field and a major regional pipeline system. The assessment reports generated from the activities were utilized to identify potential environmental liabilities associated with the production and storage of crude oil.
Served as Project Manager over the Phase II environmental investigations of three major pipeline acquisitions for a major gas gathering company. The work was performed to determine the extent of hydrocarbon (natural gas liquids) and mercury impacts to the soil and groundwater from the production, storage, and metering equipment along the pipeline, and at approximately 65 processing facilities. Cost analyses were then performed in order to adjust the property sell price to accommodate anticipated regulatory directives for corrective actions.
Once the gas gathering systems were acquired, Mr. Littlejohn conducted Phase III site assessments and based-risk assessments on the facilities identified as requiring further corrective actions. The results of the risk assessments were used to justify limited remedial actions, establishment of institutional controls, and regulatory closure.
Served as Project Manager over the closure of a 45-well oil field, located in a politically and environmentally sensitive setting, near federally protected recreation and wilderness areas in Colorado. The project required the performance of Phase II and Phase III environmental assessments, the coordination and supervision of the plugging and abandonment of oil wells, the destruction and removal of a large tank battery, and the disposition of hydrocarbon contaminated soil and naturally occurring radioactive material (NORM) contaminated sludge. Although the state where the oil field was located had not yet promulgated formal risk-based corrective action guidelines, Mr. Littlejohn was able to support a closure option using a generic ASTM risk assessment with standard EPA default parameters.
Served as regulatory and environmental oversight liaison for large working cattle ranch in West Texas. Activities included evaluation of surface water and groundwater resources, oversight of assessment and remediation of a gasoline refinery, and negotiations with oil production companies and their legal representatives concerning hydrocarbon-, salt-, and chemical-impacted soil and groundwater.
Assisted in the removal of 32 mercury gas flow meters from a crawl space beneath a gas plant office building. The mercury meters were dismantled, placed in steel drums, manifested as hazardous waste, and transported to a licensed facility for recycling. Mercury-impacted soil was also removed from the former storage area and manifested for disposal. Residual vapor concentrations were monitored during the remediation operations and following project completion to justify continued utilization of the building by gas plant personnel. Level B personal protective equipment and confined space entry procedures were required for these tasks.
Performed several Phase II and Phase III environmental assessments at large chloride release sites which utilized electro magnetic evaluation to supplement traditional soil and groundwater delineation methods resulting in a significant reduction in long-term monitoring costs for the client.
Conducted several safety and environmental compliance audits at large industrial, petroleum processing, and manufacturing facilities. Many of the facilities included the generation, treatment, storage, and shipment of hazardous and non-hazardous waste (solid/liquid). In addition, Mr. Littlejohn conducted both formal and informal environmental compliance audits at solid and liquid waste disposal facilities using investigation formats both supplied by the client or developed in-house.
Environmental Site Remediation:
Served as the Project Manager over several hydrocarbon-impacted groundwater sites where monitoring and remediation was conducted. The corrective actions were performed to achieve target clean-up levels established by the risk-based assessments conducted during the characterization phase. The projects include aggressive remediation, passive remediation, and monitoring to verify the plume stability and support a “no further action” closure option. Historically, Mr. Littlejohn has been very successful in negotiating regulatory approved closure at several petroleum facilities and fuel UST sites utilizing deed restrictive covenants and risk-based controls to insure the protection of human health and the environment.
Provided assistance and guidance in the start-up and operation of a large soil vapor extraction/air sparge remediation system that utilized a CADOX burner to treat off-gases.
Participated in groundwater site characterization activities, which were used to help identify the appropriate remedial action technology at sites that required an engineered treatment to achieve risk-based target concentrations.
Negotiated with land owners and regulators to utilize brine water spill closure techniques developed by the landfill industry to achieve in-situ closure options, resulting in tremendous cost savings over traditional dig and haul remediation methods.
General Consulting Services:
Served as an investigator and project manager for numerous Phase I environmental assessments at commercial and industrial facilities.
Provided oversight and reporting for numerous UST removal projects including approximately 30 emergency diesel generator tanks for a major telephone utility company in Texas.
Provided detailed Phase I investigation, closure oversight, and reporting for a large crayon manufacturing facility.
Prepared Spill Prevention Control and Countermeasure (SPCC) plans, Superfund Amendments and Reauthorization Act (SARA) Title III, Tier II reports, Occupational Safety and Health Administration (OSHA) compliance programs, and Underground Injection Control (UIC) class II permits for several small oil production companies.
Provided assistance and oversight in the preparation and reporting associated with a waste disposal permit and a large cheese manufacturing facility.

In addition, Mr. Van Deventer conducted both formal and informal environmental compliance audits at solid and liquid waste disposal facilities and manufacturing facilities using formats supplied by the client or developed in-house.
Project Manager and provided staff support in performing numerous Phase I, II and III environmental site assessments for various commercial and industrial properties. Most of these assessments were performed for oil and gas producing properties prior to property transfer. Followup work was often required to delineate the extent of hydrocarbon and metal impacts to soil and groundwater.
Project Manager for an Environmental Assessment that is related to a modified land sale of BLM land in New Mexico where it is being proposed to use an existing caliche pit as a centralized surface waste management facility for disposal of drilling and reserve pit material with the intended result of restoring the wildlife and plant habitat.
Prepared environmental investigations for over 100 underground storage tank (UST) sites for major retail fuel stations, trucking and bus depots, and telecommunication facilities in Texas, New Mexico, and Tennessee. Several of these properties required complete soil and groundwater evaluations, risk assessment, and remedial action.
Environmental Site Remediation
Provided
oversight and staff support in the design, installation and
implementation of various groundwater remediation projects including
an air sparging/soil vapor extraction system at a refinery and gas
plant, a groundwater recovery system at a former gas plant, and
product recovery systems at several petroleum refineries and gas
plants. Mr. Van Deventer also analyzes the site data to evaluate
the performance of these remediation systems in meeting site cleanup
goals.
Implemented
and managed numerous groundwater sampling programs in which the
monitoring of natural attenuation processes was used as the
preferred response to the remediation of dissolved hydrocarbons.
Through analysis of various biological and chemical parameters,
including aerobic bacteria populations, hydrocarbon utilizing
bacteria populations, dissolved oxygen, nitrate, sulfate, methane
and carbon dioxide, Mr. Van Deventer has demonstrated that natural
attenuation processes have adequately limited the migration of
hydrocarbon-impacted groundwater within the property boundaries for
specific sites.
Served as project manager and site remediation specialist at a gas processing plant which included the removal of 32 mercury gas flow meters from a crawl space beneath an office building. The mercury meters were dismantled, placed in steel drums, manifested as hazardous waste, and transported to a licensed facility for recycling of the mercury and other components. Mr. Van Deventer developed and implemented the subsequent mercury remediation work plan that involved the excavation, waste classification, treatment and disposal of mercury contaminated soil identified at the facility. Level B personal protective equipment and confined space entry procedures were required for these tasks. Mr. Van Deventer gave a presentation of this project at the International Petroleum Conference in November 1999.
Served
as project manager for a sampling project which involved
characterizing mercury contaminated soil at over 500 gas meter
sites. Subsequent work for this project included the excavation,
waste classification, treatment and disposal of an estimated 500
tons of mercury contaminated soil.
Provided staff support in characterizing and remediating mercury-contaminated soils at several gas metering sites within a large gas producing field. During this project he participated in the sampling, excavation, waste classification, and disposal of approximately 100 tons of mercury contaminated soil.
Other
Technical Experience
Prepared
Spill Prevention Control and Countermeasure (SPCC) plans; numerous
site health and safety plans in which he frequently acted as the
on-site health and safety officer; and developed a Quality Assurance
Project Plan (QAPjP) for a major DOE facility
Performed
waste management services involving the characterization,
manifesting and disposal of various types of hazardous and
non-hazardous waste. Responsible for documentation control.
Performed
audits, reviewed required reporting documents, and implementation of
wastewater, stormwater, underground injection control, drinking
water, and SPCC programs.
Performed
contributing role in air permit compliance audits, Title V annual
compliance certification, NSPS and NESHAP monitoring, recordkeeping,
and reporting, upset and excess emission reporting, and other
compliancing reporting.
Conducted
numerous aquifer tests to determine well yields and hydrogeologic
characteristics. He has also analyzed and compiled hydrologic and
analytical data using groundwater flow and chemical mass transport
models for application to risk evaluation/assessment and/or remedial
action plans.
Utilized
various geophysical surveying equipment in environmental
investigations. At an oil producing site, he correlated water
quality data with the results of an electromagnetic conductivity
survey to conclude that the source of high chlorides in two water
supply wells were from past oilfield activities. The survey
supported evidence that the magnitude and extent of impacted
groundwater was limited, and risk to private water wells in the
subject area was low.
Serving
as a hydrologist with the Water Resources Division of the U.S.
Geological Survey (USGS), Mr. Van Deventer participated in numerous
hydrological investigations, including irrigation-drainage
contamination problems near Casper; Wyoming, water quality and
stream flow characterization and monitoring at over 50 stream
gauging sites throughout Wyoming; fracture flow analysis and
groundwater contamination studies at the former Department of Energy
(DOE) In Situ Oil Shale Retort Facility in Rock Springs, Wyoming;
and water quality and stream flow monitoring in burned areas near
Yellowstone National Park after a major forest fire in 1988.
Serving
as a senior logging technician for a major geophysical logging
company, Mr. Van Deventer participated in a wide variety of
hydrogeological investigations and mineral exploration and
development projects. His duties involved the acquisition, analysis
and interpretation of various geophysical logging parameters
including natural gamma, spontaneous potential, resistivity (long
