The South Texas Project continues to operate without offecting the population or the environment by maintaining the calculated doses for people living in the crea 10 less than one millirem. Environmental programs at the site monitor known and predictable relationships between the operation of the South Texas Project and the surrounding area. These monitoring programs verify that the operation of the South Texas Project has minimal impact offsite and is well wi?hin state and federal regulations and guidelines. These programs are verified by the State of Texas, 1-2

l ANNUAL OPERATING REPORT 1996 SOUTH TEX AS PROJECT ADDENDUM oF TABLES , 1996 Radiological Environmental l Monitoring Program Analysis Summary An analysis summary for all of the required samples is given in Table 3. The table has been formatted to resemble a United States Nuclear Regulatory Commission industry standard. l Modifications have been made for the sole purpose of reading ease. Negative values are reported in this table as recommended by the United States Nuclear Regulatory Commission. Reported negative values are required to do long term studies where the true values are near zero or when there exists a negative bias in the measurement. l Media type is printed at the top left of each page, and the units of measurement are printed at the top right. The first column lists the activity or specific radionuclide for which each l sample was analyzed. Total analyses performed for the indicated nuclide/ the total number of nonroutine samples analyzed is given in the second column. (A nonroutine measurement , is a sample indicating a value greater than the reporting levels for Radioactivity Concentrations in Environmental Samples.) The " LOWER LIMIT OF DETECTION" column lists required values. Not all of the listed analyses or radionuclides have required lower limits of detection. Typically, the values achieved are significantly lower than the required. A set of statistical parameters are listed for each radionuclide in the remaining columns. The parameters contain information from the indicator locations, the location having the highest annual mean, and information from the control stations. For each of these groups of data, the following is calculated:
. The mean value (including negative values and values below the lower limit of detection).
. The number of analyses whose values were greater than the lower limit of detection /
the total number of analyses.
- The lowest and highest values for the analysis.
The data placed in the table was changed in 1995 from the previous reports to only include ' the data from the samples listed in Table 1. Additional thermoluminescent dosimetry is utilized each quarter for quality control purposes. The number of analyses will be the same as required with the addition of four groundwater duplicate samples, seven bottom sediment samples and six duplicate surface water samples. Vegetation and wildlife samples vary in number according to availability. This change in the data may appear to cause some inconsistencies between current and past data but will provide for more consistency in the future. l l l 8-15
