During the fourth quarter of 1987, over 1700 samples which represent more than 5200 analyses and measurements were collected. More than ten real-time monitoring stations, which telemeter 10-minute averaged readings on radiation levels, total rainfall, flows, and water or air quality parameters around ORNL also reported data. In addition, three meteorological towers sent climatological data to a host computer every 15 minutes. Uranium concentrations on air filters located at stations near the Y-12 Plant (40, 45, and 46) were elevated above normal levels due to a release from the Y-12 Plant during October. Soil concentrations of /sup 234/U and /sup 238/U were significantly higher at the stations closest to the Y-12 Plant (40 and 45). /sup 235/U was significantly higher in soil at station 40 than at other stations. Cobalt/en dash/60 concentrations in Melton Branch water were significantly lower during this quarter than previous quarters because there was no discharge from the HFIR ponds. These ponds appear to be the source of most of the /sup 60/Co in Melton Branch. There were a total of 22 noncompliances associated with the NPDES permit during the fourth quarter of 1987. Fifteen of these were violations against a permit limit and the remainder were administrative failures in either collecting or analyzing required samples. Where appropriate, corrective actions or investigations are currently underway to address these noncompliances. Eight of the noncompliances were associated with high concentrations of total suspended solids at several of the Category I and II outfalls. Because no appreciable precipitation had occurred for over two weeks prior to the December sampling date, the samples taken would be expected to contain the first-flush of a 2 to 3 week accumulation of dust and other particulate matter from the areas drained by the outfalls.
