Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
The facility is currently operating under the 0.04 MGD phase of the
permit. An A to C has been issued for the 0.08 MGD phase. Current limits
are being met.
Instream data indicates higher D.O. values in summer than in winter
(very suspect). All D.O. values are above 5 mg/l.
