Waste load evaluation for water quality segments no. 2421, 2422, 2423, and 2424 of the Trinity - San Jacinto estuary (Galveston Bay System)

The purpose of this study is to define waste treatment levels that will result in the stream segment meeting applicable stream standards. The general approach followed is: a) describe the stream segment, b) define the water quality problem, c) define assimilative capacity by mathematical modeling, and d) establish acceptable waste discharges and schedules of implementation. Although these four segments are currently classified as Effluent Limited Segments, this waste load evaluation is prepared to be used as a guide in developing NPDES permits in the area to maintain the existing good water quality.
