During the inspection, it was noted that the refrigerator of the influent composite sampler was not functioning, Board staff noted that the internal temperature of the influent composite sampler was reading 10°C. WDRs Standard Provision III.B requires the Discharger to conduct sampling in accordance with 40 C.F.R. Part 136, which specifies a sample preservation temperature of 4 degrees Celsius plus or minus 2 degrees for proper preservation. Since the influent composite sampler is not maintained within the required temperature range, it does not meet sample preservation requirements, in violation of Standard Provision III.B. |
