seeks to extend the existing

The second change involves the quarterly testing
currently required by the existing permit. Analytical results
for the samples taken in May, August and November, 1990 have not
revealed any specified pollutant to exist in levels equal to or
greater than method detection limits, (see attachment 2). Also,
priority pollutant analyses performed on samples taken from
outfalls 001 and 002 have not revealed the presence of pollutants
either, (see attachment 3). Quarterly toxicity tests performed
during the same period have demonstrated that acute toxicity
problems do not exist. Du Pont requests that pollutant testing
be eliminated and toxicity testing be performed on an annual
basis.
