Water Quality
Permitting Section
Please find attached permit renewal application for your review. We would like to request that the new
permit be issued as a General Permit NCG59000 for Conventional Water Plant. The flow through drying
beds is very intermittent. The water is generated from settling basin washouts (3-4 times per year) and
backwashing 2 filters every 96 hours. When the filters are backwashed every 7-10 days there is an
average of .050 gallons used in the process, this allows several days for settling and evaporation in the
drying beds, which leads to very little discharge flow (7-10 days on average detention time). We
understand that modified compliance monitoring may be made available to eliminate several current
parameters including; Aluminum, Total Copper, Manganese, Total Phosphorus, Total Nitrogen, Whole
Effluent Toxicity Monitoring. We have recorded (PASS) results WET for previous permit cycle. Recent
(9-13-16) Aluminum results were 105 ug/l, Copper results ND, Manganese 625 ug/I and Total
Phosphorus ND.
If you have additional questions that I might be able to help you with, please contact me, Kevin Yates at
madisonwtpna townoftnadison.org.
Sincerely,
levin
