1.0 Executive Summary This Annual Radiological Environmental Operating Report describes the Union Electric Company, Callaway Plant Radiological Environmental Monitoring Program (REMP), and the program results for the calendar year 2004. It is submitted in accordance with section 5.6.2 of the Callaway Plant Technical Specifications.

Section 2.0 describes the Radiological Monitoring Program.

Included is the identification of sampling locations, descriptions of sampling and analysis procedures, analysis results, data interpretations, and program modifications. Quality assurance results, sampling deviations, unavailable samples, and program changes are also discussed.

Section 3.0 describes the Non-Radiological Monitoring Program. Included are any unusual or important events, Environmental Protection Plan noncompliance, non-routine reports, and plant design and operation environmental evaluations.

During 2004 the Callaway Plant operated in compliance with the Offsite Dose Calculation Manual (ODCM) requirements.

Comparison of results for 2004 to preoperational data and data from previous years show no significant differences.

Results from the REMP indicate the Callaway Plant has had no significant radiological impact on the health and safety of the public or on the environment.

Indicator samples are The objectives of the REMP are to monitor collected from locations which could be influenced potential critical pathways of radioactive effluent to by plant effluents. Control samples are collected man and determine the radiological impact on the at locations that are not significantly affected by environment caused by operation of Callaway plant operation.

Radiological Monitoring Program 2.7 Data Reporting Conventions 2.8 Radiological Environmental Monitoring Program Annual Summary.

Lower Limit of Detection The REMP Summary is presented inTable VI in The lower limit of detection (LLD) used in this accordance with NRC Regulatory Guide 4.1, report is per NRC Regulatory Guide 4.1, Rev. 1, Rev. 1,"Program for Monitoring Radioactivity in "Program for Monitoring Radioactivity in the the Environs of Nuclear Power Plants", and the Environs of Nuclear Power Plants", and the NRC NRC Branch Technical Position, November Branch Technical Position, November 1979, "An 1979, "An Acceptable Radiological Acceptable Radiological Environmental Environmental Monitoring Program". Incases Monitoring Program". The LLD is defined as the where the activity is found to be below the smallest concentration of radioactivity material in a sample analysis minimum, the activity is sample that will yield a net count (above system reported as < LLD.

probability with only 5% probability of falsely With the exception of a small indication of concluding that a blank observation represents a tritium in riverwater, there was no measurable

The maximum LLDs for radiological environmental sample analysis is presented in Table l1l.

Data Reporting Positive sample results are reported with a 2 sigma counting uncertainty (corresponding to the 95% confidence level). In cases where the activity is found to be below the sample analysis minimum, the activity is reported as Not Detected " .
