1.0 AVEVJWKExecutive Summnazr This Annual Radiological Environmental Operating Report describes the Union Electric Company, Callaway Plant Radiological Environmental Monitoring Program (REMP), and the program results for the calendaryear 2002. 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 non-compliance, non-routine reports and plant design and operation environmental evaluations.

During 2002 the Callaway Plant operated in compliance with the OffSite Dose Calculation Manual requirements.

Comparison of results for 2002 to pre-operationaldata and data from previous years show no significant differences.

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

approximately eighty miles west of the St. Louis metropolitan area. The Missouri Riverflows by the site in an easterly direction approximately five miles south of the site at its closest point.

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

Samples are collected from waterborne, airborne, ingestion, and direct radiation pathways.

The types of sample media collected are: milk, surface water, groundwater, shoreline sediment, bottom sediment, soil, wetlands, fish, vegetation, airborne particulate, airbome radioiodine and direct radiation (TLD). Indicator samples are collected from locations which could be influenced 2

3.0 NbrP-dIQkola 32 ErjtoE ML zan Callaway Modification MP 01-2007A Description of Change:

MP 01-2007A is a partial backfill of the unused Callaway Plant Unit 2 excavation. The fill material was from the soil that was stockpiled from the plant construction.

Evaluation of Change:

The modification involves partial filling of the unused unit 2 excavation with soil that was re-moved and stockpiled during construction. The modification will only disturb areas that were previously disturbed during construction.

As a result of this modification, some stormwater that is now discharged from the storm water ouffall 12 will be discharged from stormwater ouffall 10. These stormwater ouffalls are already in our NPDES permit. Although there will be some change in individual outfall flows, there will be no net increase in flow from the stormwater outfalls. Retention ponds will main-tain effluents from stormwater ouffalls within permit limits.

This modification will not significantly affect the concentrations, frequencies or types of effluent being discharged from the plant, and does not affect the current plant power level. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of appen-dix Bto the Callaway Plant Operating License.
