Genera Site Information
- Chapter 1 provides information about the site and lays out the licensing notification and approval requirements relating to any deviations from or changes to the LTP.
- Addresses historical information about the site as well as summarizing the content of the remaining seven chapters
S) UCactrztion 2Et i
- Provides information regarding A..y the radiological state of the site using input from the historical site assessment, site spill records and continuing characterization data.
- Characterization will continue to take place and the LTP will be updated as necessary as new data becomes available.
LTP Chapter 3 12 FRemaining Decommision"ing Activities
" Describes the methods and sequence of remaining decommissioning work.
" Done at a high level, in other words, major activities are identified and an estimated completion date is provided so the NRC can identify any inspections and technical resources that will be needed.
" The chapter also includes site dose estimates, waste volumes and radiological effluents for the entire decommissioning.
L h a pt--e 4~*~4b 13
- Describes the means and methods to accomplish the remaining work scope of remediation to meet the NRC's release criteria.
Include a detailed description of the techniques that will be employed to remove or remediate surface and subsurface soils, groundwater, and surface water and sediments.
SLTP Ch.ape 5 o,14 i* ~ ~~ ~ ~ ~ ~ ~: .............

'-.: ". .c..
- The LTP describes the final radiation' survey plan for demonstrating that the plant and site will meet the release limits.
- The final status survey is the radiation survey performed after an area has been fully characterized, remediation has been completed, and the area is ready to be released.
- The purpose of the final status survey is to demonstrate that the area conforms to the radiological criteria for license termination.
15 LT Chptr ace W Com Radiological Criteria
- Most technical of the chapters
- Describes the process implemented to develop the site dose models and Derived Concentration Guideline Levels (DCGLs), including input parameter justification and sensitivity analyses.
- DCGLs are radionuclide-specific values determined by a software program that correlate to the site release criteria.
P Chapter 7 16 F nancial Status Describes the financing of the * . .*
decommissioning project, with very detailed cost estimates which .
usually includes some proprietary information related to contractual information.
- Funding status for the operation of the temporary spent fuel storage is not included in this chapter, however it is required in the annual financial assurance document sent to the NRC.
i17 Suplmettoth E~onena Repoft.
Provides an update to the 1984 environmental report.
The goal of this chapter is to demonstrate that the project poses no environmental impacts that would exceed those described in the NRC's Generic Environmental Impact Statement.
- Describes any new information or significant environmental changes associated with the site-specific termination activities from the time the dismantlement and decommissioning activities began until the license isterminated.
