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 2005. It is submitted in accordance with section 5.6.2 of the Callaway Plant Technical Specifications.

Section 2.0 describes the Radiological Environmental 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 operational environmental evaluations.

During 2005 the Callaway Plant operated in compliance with the Offsite Dose Calculation Manual (ODCM) requirements.

Comparison of results for 2005 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.

Sample locations for the REM P are shown in Figures I and 11. Table I identifies the location code, description, and sample type. Table II specifies 2.2 Program Design the collection frequency and required analysis.

The sample locations, frequency of sampling, and sample analysis requirements originate from the Callaway Plant Off Site Dose Calculation Manual, NPDES Permit, and continuation of the Callaway Plant Pre-Operational Environmental Monitoring Program.

This sampler is located in an area where it is exposed to a dustier environment than any of the other samplers and this may be a contributing factor to the repeated failures at this location.

A deviation to the sampling occurred for all the air stations for the week of March 24, 2005 to March 30, 2005 when the air samples were lost in shipping to the vendor lab (CAR 200502314). A second deviation is when the samples were sent with a cooling tower blowdown sample on September 29, 2005. The samples were dried by the lab and analyzed. The results of the air samples do not appear to have been impacted due to the samples getting wet in transport (CAR 200506304).

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 (ND).
