The report gives results of a source test program at a Koppers-Totzek (K-T) coal gasification plant operated by AECI, Ltd. at Modderfontein, Republic of South Africa. Much of the effort was focused on wastewater streams. Wastewater treatment, consisting of a clarifier and settling pond, was adequate to produce a final discharge that had lower pollutant levels than the fresh input waters supplied to the plant. The report contains complete data and describes the K-T process and the Modderfontein plant.

"The report gives results of a source test program at a Koppers-Totzek (K-T) coal gasification plant operated by AECI, Ltd. at Modderfontein, Republic of South Africa. EPA is interested in K-T process because process economics and demonstrated commercial reliability make it a viable prospect for U.S. applications. Responsibilities for sampling, analysis, and engineering descriptions of the plant were shared by TRW and Krupp-Koppers GmbH of Essen, Federal Republic of Germany. EPA's phased approach for environmental assessments was followed. Level 1 and Level 2 data were collected along with priority pollutant screening data. Much of the effort was focused on wastewater streams. Watewater treatment, consisting of a clarifier and settling pond, was adequate to produce a final discharge that had lower pollutant levels than the fresh input waters supplied to the plant. The report contains complete data and describes the K-T process and the Modderfontein plant. The Source Test Evaluation (STE), intended as an initial effort, was somewhat limited in scope. Recommendations for future STE programs are provided."--Abstract.
