10/1/2026 This email is to notify you that we had an exceedance in the permit level for benzene for a sample collected on 9/21/2026 for the above referenced NPDES permit. The reported level of 0.0077 mg/L for benzene exceeded the permit level of 0.005 mg/L. We are currently going over a couple of operational aspects for the treatment system to determine a cause and to prevent any future exceedances. Robert Kalinski, P.E. Senior Engineer KRISTI BURG
