Chemical oxygen demand, total organic carbon, total suspended solids, and ammonia were inadvertently omitted during the initial sample analyses. The discharge points were resampled on November 18 and 19, 1987. Included are the results for the cooling tower blowdown (Serial No. 001) and low volume waste (Serial No. 004). The metal cleaning waste (Serial No. 003)' has not discharged since the start-up of the Harris Plant and is, therefore, not included in this submittal. The data provided is considered to be .reflective of the quality and quantity�,� of 'the wastewater discharges ^-as_s :ed with plant � operations at the -time -of -- the\ sampling. The results of the initial low volume waste sample (Serial No. 004) seems to indicate that the sample was collected during regeneration of the dem neralizers. No permitted limits were exceeded.' If you .have any specific questions concerning this submittal, please contact, J. M. McDowell at 836-6920. TLP/dsm (4286TLP) Enclosure cc: Mr. George Everett Mr. R. W.
