***Ventilation Index is derived from transport wind
multiplied by the mixing height in 100`s of ft.
Categories are a generalized indicator and users
are encourage to develop criteria that are
suitable and representative of dispersion
conditions in their local area of interest.
Categories: low (< 200), moderate (200-500),
high (500-700), and very high (> 700).
