Summary
Components in use are described in a staff report (dated May 4, 1994) and a letter from the permittee's engineer
(dated July 13, 1994). Subsequent discussion of the draft permit with Lee Spencer (DEH — WSRO) resulted in
most components being removed from the list on the permit Supplement page. Lee pointed out that the other
components are permitted by DEH, as they are part of the drinking -water treatment system, not the (filter
backwash) wastewater system.
No DMRs were present in Central Files. Info from the permittee indicates that no discharge has occurred from
this facility — all supernatant is returned to the presettlement pond. The permittee wishes to retain the permit for
possible future discharge.

Dear Mr. Goodrich:
Please consider this letter a clarification of our application for
the above referenced permit.
The Sparks Road facility was originally constructed with a
presettling pond for raw water and twin gravity settling sludge
lagoons for clarifier blowdown and filter backwash waters.
Historically, clarifier blowdown and filter backwash waters have
been treated in the twin sludge lagoons with supernatant being
returned 'to the presettling pond and passed back through the
treatment train.
Due to the buildup of process chemicals and organics in the twin
sludge settling lagoons and the increase in THM formation potential
when the supernatant from the twin sludge settling lagoons is added
to the presettling pond, Davie County wishes to discharge -
supernatant from the lagoons to an unnamed tributary of the Yadkin
River.
It is our opinion that no additional treatment will be requiredr4or
the supernatant from the lagoons to meet the discharge limitations
specified in the draft permit that we received from your officeoon
July 12th. On behalf of Davie County, we would like to regnst
that a revised permit be issued for discharge of supernatant frolt
the existing twin settling lagoons without further treatment.
