Dear Mr. Check:

REQUEST FOR ADDITIONAL INFORMATION - Q290.11R

Reference:

1. Letter, J. R. Longenecker to P. Check, " Request for Additional Infomation - Q290.llR," dated December 21, 190)

RESPONSE TO NRC Q290.11R

1. Narrative comments about substrate characteristics and likelihood of finding endangered mussels were supplied by Donald C. Wade, TVA biologist. The tabular list of endangered mussel records were com-piled by John J. Jenkinson, TVA biologist (malacoligist).

2. Literature citations for Ortmann, 1918, and Gooch et al., should have been attached to the end of the table. They are as follows:

Ortmann, A. E., 1918. The Nayades (freshwater mussels) of the Upper Tennessee Drainage. With notes on synonymy and distribution. Pro-ccedings of the American Philosophical Society, 57:521-626.

Gooch, C. H., W. J. Pardue, and D. C. Wade, 1979. Recent mollusk Q." investigations of the Tennessee River, 1978. Draft report of the Water Quality and Ecology Branch, Division of Environmental Planning,

'- Tennessee Valley Authority, 126 pp.

3. All twelve freshwater mussel species on either the U.S. Fish and Wildelife Service or on the TVA genr ated lists are typically found on stable gravel or cobble substrates. Marginal habitats for the Plethobasus species, Lampsilis orbiculata, Dromus dromas, and Pleurobema plenum might extend to sand or clay substrates if the bottom material was current-swept, stable and penetrable enough to allow the mussels to dig in. Solid bedrock or shifting mud or sand substrates, which characterise the river bed in the vicinity at and downstream of the CRBRP site, are unsuitable habitats for nearly all freshwater mussel species including all of the species on either of the lists prepared by the CRBRP site.

4. Know ranges of species involved (live records 1975-date):
