Christie,
In reviewing the new permit issued to this facility dated January 25, I noticed that the sample type was
composite for whole effluent toxicity. The previous permit had been modified to specify the sample type as
grab. When I went back to look at the draft permit that I reviewed in the fall, the sample type was indeed
composite; so I missed this when I reviewed the draft.
The problem is that I'm pretty sure the facility will not be able to collect a composite sample. Is there any way
we can address this other than a permit modification and, if not, is a permit modification even feasible at this
point given personnel shortages?
