Dear Mr. Seidle:

River Bend Station Units 1 & 2

- Docket Nos. 50-458, 50-459 Alligator Bayou Crossing - Status Report With regard to Gulf States Utilities (CSU) letter to you dated .

June 19, 1978, GSU is hereby submitting its first status report of the activities to date regarding the environmental studies for the Alli- .

/

gator Bayou crossing.

Water quality measurements, phytoplar.kton, microzooplankton, fish larvae, and benthos data were collected during the March-May 3978 ~

quarter. The Alligator Bayou crossing study has been considered fully operational since early July 1978, and data vill be collected for the River high and low water cycles anticipated for the remainder of the s t u dy,<

By way of clarification to GSU's response 3 in the June 19, 1978 letter, Louisiana State University (LSU) provides GSU with a narrative summary at the end of each quarter that includes the status of the monitoring capability (e.g. confirmation of sampling activities), and also addresses any adverse environmental impacts noted during that quarter and includes an overall assessment of the impacts from program start through that quarter. The actual collected data is not trans-mitted to GSU cach quarter, but is retained by LSU to be submitted in the yearly report.

The data collection effort is in the initial phase (March-May 1978) and the major monitoring equipment has recently been obtained. In addition, there was sone difficulty in obtaining access to monitoring stations. Deterioration of the access road into the Needle Lake area had hampered data collection in that vicinity. GSU has consulted with LSU regarding this and has upgraded the access to Needle Lake to help facilitate the monitoring. Also is has been brought to CSU's attention h

l that overbank flooding of the River above the Alligator Bayou crossing l may have a tendency to complicate the study effort. CSU is working with LSU to minimize this potential effect on the study ef fort and to assure the objectives of the study are met.

In summary, there is not adequate information at this early stage

, in the Alligator Bayou crossing study to nake any conclusion regarding the culvert crossing environmental impact.

Sincerely,
