✦ Synopsis
In 1979, the Upjohn Company entered into negotiations with the State of Connecticut for renewal of their NPDES permit. During these negotiations, control of odors from the site became an issue, and several methods of eliminating potential odor sources from the facility were examined. At this point in time, the waste treatment system consisted of a series of lagoons, the last one being an aeration lagoon with two 150 horsepowerfixed aerators. One of the many potential odor sources to be addressed was this lagoon. As part of the permit renewal conditions, the State of Connecticut DEP ordered Upjohn to construct an air supported enclosure over the 9,500-1 1,350 m3 aeration lagoon. Exhaust air was to be monitored and treated with the use offixed bed granular activated carbon absorbers. This resulted in a project costing wer $620,000 to construct and an additional $75,000-$100,000 per year to operate.
