The water treatment facility is permitted to treat 1.5 MGD, yet there is no permitted
flow in permit. DWQ policy is normally not to limit WT? flow in permit.
The treatment system consists of two inorganic solids settling basins and recycle pumps.
WT? discharges to an unnamed tributary that flows into the stream that connects Forest
Lake to the Second Broad River. The unnamed tributary and the stream that connects
Forest Lake to the Second Broad River are both Class WS-V while the Second Broad
River is Class WS-IV.
Compliance Summary
Effluent data reviewed from January 1995 through May 1998 indicated no violations.
The facility had only discharged twice during this period (3/95 and 2/96). DMRs
indicate that water is recirculated to head of facility. Forest City is currently conducting
construction at their WTP and want to renew the permit in case they must discharge
during construction. However, Forest City plans on sending their wastewater to Forest
City WWT? in about two years.

Finally, I am responding to your requests for some interim guidance on water treatment
plants until the full study characterizing water plant discharges can be completed. Per

**All facilities that u 'Mize alum flocculation
***All facilities that perform brine recharge of water softeners and
reverse osmosis plants
It has been decided that a toxicity condition will not be included in the permit, as
recomended in memorandum dated 9/18/92 (copy attached), until further information is
collected and reviewed. Let me reiterate that this is an interim solution. Once we have
completed a survey of water plants and further review of the chemical and toxicological
effects of these types of discharges, we will be finalizing the permit requirements. N you
have any question, please contact me.
