The results of this survey were submitted in our report dated May 22, 1973 and included in the Environmental Report submitted to the Atomic Energy Commission in August, 1973. Houston Lighting & Power Company has recently authorized a one-year biological monitoring program to be perfomed basically as outlined in Chapter 6 of the Environmental Report. The objective of this project description is to further define the monitoring program. The program defined herein is intended to be flexible to allow adjustment of the dynamic nature of both aquatic and terrestrial ecosystems. Consequently, if data obtained reveal sensitive areas within either system, sampling schedules and techniques can be adjusted to meed these situations.biological monitoringwater qualityTechnical Report
