k further conpflcation has been that flows through the acti-

vated

sludge

plant

have

been

reduced,

presumably

by water con-

servation,

and

thus available dilution from this source has beer

lessened.

The environmental impact of a 12 mg/i fluoride discharge

on Kress Creek is said by the petitioner to raise the water quality

to only 1 0 mg/i compared to the

1 4 mg/i standard of Rule 203(f).

Presumably, this computaticn is made using the entire flow of ICress

Creek and is not computed at the edge of the mixing zone.

The

latter is the correct procedure.
