Environmental Description

DOE-STD -3009-94

Location of the site relative to prominent natural and man- made features

such as rivers, lakes, mountain ranges, dams, airports, population centers.

General location map to define the boundary of the site and show the

correct distance of significant facility features from the site boundary.

Public exclusion areas and access control areas.

Identification of the point where the Evaluation Guideline is applied.

Additional detail maps, as needed, to present near plant detail, such as

orientation of buildings, traffic routes, transmission lines, and neighboring

structures.

1.3.2 Demography

Population information based on recent census data is included to show the

population distribution as a function of distance and direction from the facility.

Demographic information emphasizes worker populations and nearby residences,

major population centers, and major institutions such as schools, hospitals, etc., to

the degree warranted by potential offsite consequences. The minimum area

addressed is defined by the area significantly affected by the accidents analyzed in

Chapter 3, "Hazard and Accident Analyses."

1.4

ENVIRONMENTAL DESCRIPTION

This section describes the site's meteorology, hydrology, and geology.

1.4.1 Meteorology

This section provides the meteorological information necess ary to understand the

regional weather phenomena of concern for facility operations and to understand

the dispersion analyses performed.

1.4.2 Hydrology

This section provides the hydrological information necessary to understand any

regional hydrological phenomena of concern for facility operation and to

understand any dispersion analyses performed. Include information on

groundwater aquifers, drainage plots, soil porosity, and other aspects of the

hydrological character of the site. Discuss or reference, to the degree necessary,

the average and extreme conditions as determined by historical data to meet the

intent of this section.

1.4.3 Geology

This section provides the geological information necessary to understand any

regional geological phenomena of concern for facility operation. Describe the

nature of investigations performed and provide the results of the investigations.

Include geologic history, soil structures, and other aspects of the geologic

character of the site.
