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.

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.

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