Dear Mr. Johnson:

1 I

l We are pleased to enclose our report covering our investigation of the Crystal River site; in which we examined the sensitivity of the site's ecological

} communities to salt drift which might be introduced if the plant cooling systems tre ch&nged to salt or brack-ish water cooling towers.

i

! In this study we determined by aerial photo analyses, literature search and field investigation, the j make-up of the several ecological communities and habitat types which constitute the Crystal River site. The am-bient or existing salt content of foliage and of soil was determined for the dominant species of each community by 4

sampling and laboratory analysis.

4.

'The pertinent data points which have been estab-lished for various plant types to define their salt sensi-tivity in terms of the duration and intensity of salt ex-posed, were determined by an extensive search of literature and research reports.

It was determined that the increases in salt an-ticipated to occur in the soil as a result of cooling tower drift would not be likely to cause damage to vegetation.

Due to the uncertainties in foilage sensitivity to salt, and in the rate of deposition expected on foliage, it is

.not possible to determine if saline water cooling towers

" would cause damage to vegetation through the foliage path-way. . Of the ecological communities present, the mesophytic hardwoods are the most likely to suffer such damage, however.
