2.12.5 Historical information

The information presented in this second section should deal with the outcome of the performed ‘Historical site assessment’, but in a condensed way and focused on information that could be used for upcoming health physics and environmental risk assessments.

The content of section 2 of the archive should include the following:

2.1 Property identifications.
2.1.1 Physical characteristics.
2.1.1.1 Name of the site, owner(s)/operator(s) name, address(es).
2.1.1.2 Location, street address, city, country, state, geograpic coordinates, land registry registration.
2.1.1.3 Boundaries of the site.
2.1.1.4 Topography minute quadrangle or equivalent.
2.1.1.5 Stratigraphy.
2.1.2 Environmental setting.
2.1.2.1 Geology.
2.1.2.2 Hydrogeology.
2.1.2.3 Hydrology.
2.1.2.4 Meteorology.

2.2 Historical site assessment methodology.

2.3 History and last current usage.
2.3.1 History: years of operation; type of facilities; description of operation; regulatory involvement; permits and licenses; figures as accurate as possible about the maximum amount of present radioactive and hazardous materials in time and from which manufacturers these materials are ordered.
2.3.2 Current usage-type of facility: description of operation; permits and licenses; figures as accurate as possible about the type and maximum amount of present radioactive and hazardous materials in time and from which manufactures these materials are ordered; description of spills or releases; list of waste manifests; emergency or removal actions; quality management system in relation to known and potential contaminants and hazardous material.

2.4 Findings.
2.4.1 Known and potential contaminants and hazardous material.
2.4.2 Potential contaminated areas.
2.4.2.1 Impacted areas, known and potential.
2.4.2.2 Non-impacted.
2.4.3 Known and potential contaminated media.
2.4.4 Known and potential problematic and hazardous materials and waste.
2.4.5 Related environmental concerns.

2.5 Conclusions.

2.6 References: documents reviewed; references to other sources of information.

2.7 Appendixes.
2.7.1 Photo documentation log: original photographs of the site and pertinent site features.
2.7.2 List of accidents that affected the site and/or the environment including corrective measures.
2.7.3 List of annual radiological and chemical releases to the environment (e.g., aerosols, dust, surface and groundwater, etc.).
2.7.4 Statement or list of actions that exclude explicitly specific industrial or other activities that have never been performed at the site.
2.7.5 Statement or list of radionuclides and hazardous materials that exclude explicitly that they have been present at the site.

Important is by describing the historical and current information to include figures as accurate as possible dealing with the maximum amount present and the chemical composition and form from radioactive and hazardous materials in time and from which manufactures these materials were ordered. These figures can and will be used to perform risk assessments if needed.
