Info from permittee
Summary,
This facility is a conventional WTP, which uses aluminum sulfate and sodium hydroxide. Components in use are
described in a faxed memo from the permittee received January 25, 1999. 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.
The receiving stream is not impaired or threatened. No segments of the Yadkin River mainstem (in subbasin
30704) appear on the latest 303(d) list.
There is no record of any compliance violations by this facility in Central Files.

Subject: Modification of NPDES Permit No. NC0084425
Davidson Water, Inc. (WTP)
Davidson County
The Division is beginning the second five-year cycle of river basin planning and permit renewals. An
examination of the basin planning schedule has revealed that the timing of permit renewals does not
allow an evenly distributed workload as first envisioned. This results in problems with the efficiency
and effectiveness of the NPDES program. In an effort improve customer service, and after thorough
review of the water quality issues in your area, the Division is changing the permit renewal schedule for
all NPDES permits in your sub -basin.
This permit modification changes the expiration date of the subject permit to May 31, 1999. Please find
enclosed the revised permit cover page. Insert the new cover page into your permit and discard the old
page. All other terms and conditions contained in the original permit remain unchanged and in full
effect. This permit modification is issued pursuant to the requirements of North Carolina General
Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U. S.
Environmental Protection Agency.
If you have already submitted a permit renewal application for the subject facility, the Division will
retain the application until your permit is due for renewal. No additional forms or fees will be required.
If any parts, measurement frequencies or sampling requirements contained in this permit modification
are unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be a written petition conforming to
Chapter 150B of the North Carolina General Statutes, filed with the Office of Administrative Hearings,
Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this
decision shall be final and binding.
If you have questions about this modification, please contact Charles Weaver of my staff at the

Subject: Status of NPDES Permit NC0084425

Dear Permittee:
After a thorough review of the Yadkin -Pee Dee River basin management plan and water quality issues relevant to
the subject facility, the Division of Water Quality has decided to extend the duration of the subject permit. The
expiration date of your permit will be changed in order to allow the Division to review all NPDES discharge
permits in the Yadkin River Basin during calendar year 1999.
All terms and conditions in the existing permit will apply until a new expiration date is assigned by the Division.
Extension of existing Effluent Limitations and Monitoring Requirements does not exempt the subject facility from
the new Enforcement Policy recently enacted by the Division.
Attached to this letter is a copy of the Public Notice that is being published to announce the planned extension of
your permit. After Public Notice has been made by the Division, the expiration date of your permit will be
changed via a permit modification. No draft permit will be sent out with the Public Notice, as none of the
conditions in the existing permit will be modified.
The Division appreciates your patience and understanding to date regarding the rescheduling of the subject
permit. If you have already submitted your renewal application package, no additional fees or documentation will
be required as a result of this change to your permit's expiration date.
If you have questions about this proposed modification or about the permit renewal process, contact Charles
Weaver of my staff at the telephone number or address listed below.
Sincerely,
A. Preston Howar , Jr., P.E.

Summary
This facility is a conventional WTP, which uses aluminum sulfate and sodium hydroxide. Components in use are
described in a faxed memo from the permittee received January 25, 1999. 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.
The receiving stream is not impaired or threatened. No segments of the Yadkin River mainstem (in subbasin
30704) appear on the latest 303(d) list.
There is no record of any compliance violations by this facility in Central Files.
