U s department of energy poland initiative l.jpg

U.S. Department of Energy-Poland Initiative

  • The mission of U.S. DOE and the Polish Institute for Ecology of Industrial Areas (IETU) Katowice, Poland partnership is to establish the Risk Abatement Center for Eastern and Central Europe (RACE).

  • IETU/RACE in cooperation with the U.S. team will demonstrate the U.S. DOE process for investigation, evaluation and remediation of a hazardous waste site.

  • 1995-7: Characterization and demo of biosparging/bioventing bioremediation of oil refinery waste lagoon at the Czechowice Oil Refinery.

  • A goal is to provide a mechanism for the transfer of those techniques and technologies used in the demonstration to Poland and other countries in the region.

  • The Initiative will provide for the advancement of EM technologies for use at other DOE facilities and promote commercial development between U.S. and Polish environmental firms.


Objectives l.jpg

OBJECTIVES

  • Demonstrate Cost Effective Remediation of Czechowice Oil Refinery (COF) Lagoon by:

    • Reducing the risks associated with both the soil and lagoon water. (Risk Assesment must determine an acceptable level.)

    • Remediate to a level which will support a green zone (i.e. Grow grass.)

  • Train and Transfer Bioremediation technology to the IETU, Poland, and RACE.

  • Evaluate the technology deployed for effectiveness and cost efficiency, eg. compare passive vs. active aeration.

  • Transfer technology gleaned (isolates) to DOE sites.

Czechowice oil refinery l.jpg

Czechowice Oil Refinery

  • The Silesian Refinery Works, known as the Czechowice Oil Refinery started in 1896 when the Schodnica refinery was built.

  • A second refinery was built in 1902 by the Vacuum Oil Company which was owned by the Socony Vacuum Oil Company Inc., New York USA.

  • The first distillation unit was built in 1931 by Foster Wheeler.

  • The refinery was bombed by the Allies in 1943 and partially rebuilt by the Germans during the war.

  • Polish engineers and workers finished the restoration shortly after the war and production resumed in 1946.

  • Cresol was refined into grease with a capacity of 25,000 tons/yr.

  • Between 1959 and 1962 capacity increased to 500,000 tons/yr.

  • Thallic and turpentine oils processing was added in 1985.

  • Today’s free market products include ethyl gasoline, engine oil , fuel oil, paraffins, asphalts, and special oils.


Treatability tests l.jpg

Treatability Tests


Treatability test results l.jpg

Treatability Test Results

  • Indigenous microbes that degrade contaminants are present

  • Microbes present can be stimulated to degrade contaminants at high rate (90% reduction of TPH in <21 days) - IETU and SRTC

  • 36 Low pH (<3) organisms that degrade contaminants have been isolated (unique atributes make them patentable)

  • High clay content of some soils shows even higher stimulation than low clay content soils

  • Biodegradation of contaminants is correlated with increased CO2 production

  • pH adjustment is not as important for stimulation as nutrients (N&P)

  • Local dolomite can be used to increase pH

  • Local wood chips can be used to provide bulking agent

  • 36 isolates of unique acidophilic PAH degraders undergoing identification and molecular characterization in FY98.

Expedited site characterization l.jpg

Expedited Site Characterization

  • An expedited site characterization of the Czechowice Oil Refinery waste lagoon was performed by Ames Laboratories

  • Quantitative laboratory analyses as well as qualitative field techniques such as Cone Penetrometer based florescence probes, ground penetrating radar and horizontal well drilling was used to provide a physical and chemical characterization of the site.

  • BTEX, PAH and Metals were selected as target compounds based on the operating history of the refinery. IETU used the results to produce an environmental risk assessment.

  • The waste lagoons possess a natural clay bottom and no contaminates have been found directly beneath the lagoon. However, BTEX has been found at deeper depths which suggests a separate source.


Risk assessment l.jpg

Risk Assessment

Three Scenarios Postulated

I - Adult, On-site Future Construction/Remediation

Dermal, inhalation & ingestion during work at lagoons.

II - Adult, Industrial (I.e. Refinery Worker)

Dermal, inhalation & ingestion during associated work at lagoons.

III - Adult, On-site Groundwater, Future Irrigation

Dermal, inhalation & ingestion from groundwater during work or irrigation.
