TORMI/VATER PERM!TTING
Our permit requires our facility to complete Annual Acute Toxicity Testing for each of our outfalls.
However, due to a lack of qualifying storm events, we still have not been able to collect samples to
run this testing. We will be conducting our acute toxicity testing during the next qualifying storm event
that occurs.
Should you have any questions or require additional information, please contact Bethany Feuerstein
