WLA Summary
Standard WTP monitoring requirements (see C. Sullins memo 9/30/92) will remain in
permit. Region -Please confirm that alum compound used in treatment process.
Shelby WTP withdraws 12 MGD from the First Broad River above Brushy Creek. This
withdrawl was not taken into account when calculating the impact of other discharges on
the First Broad River. A calibrated model will allow better wasteload allocations and
provide a modeling tool for basinwide management.

RE: NPDES PERMIT RENEWAL APPLICATION FOR
CITY OF SHELBY WATER TREATMENT PLANT
NPDES PERMIT NO. NCO027197
Dear Mr. Weaver:
Attached are three (3) copies of the application for Ref. permit together with a
check for the permit application processing fee in the amount of $250.00.
The City of Shelby Water Treatment Plant is currently permitted to discharge
treated filter backwash water to the First Broad River under Permit No.
NCO027197 which expires on December 31, 1998. This application is for renewal
of the current permit.
The city requests DWQ's serious consideration of the following items for permit
renewal:
1. Documentation of the 7Q10 flow in the First Broad River at the Water
Treatment Plant discharge point.

NPDES Permit Renewal Application
Page - 2
2. A reduction in monitoring frequency from weekly to two times per month for
iron, aluminum, settleable solids, turbidity, and total residual chlorine.
3. Permit language setting non -detect equal to a value of zero for purposes of
averaging to determine compliance.
4. Please provide the City of Shelby with the Fact Sheet prepared as part of the
draft permit development, as soon as it is available.
5. Please provide documentation of methodology, data, and assumptions used in
any Reasonable Potential Analyses that may be conducted.
6. Please provide information addressing DWQ's consideration of metals
partitioning and bioavailability in the development of permit limits.
7. Please provide documentation of the reference location used in any
bioassessment evaluation.
8. We request a copy of any comments that DWQ may receive from the public
regarding this permit renewal.
We understand that DWQ has formed a Triennial Review Advisory Committee
which has made recommendations for changes to some of the surface water quality
standards. One of the recommendations of the Committee is to allow the use of
dissolved or other toxic forms of iron and other metals to develop permit limits for
the protection of aquatic life. The proposed rule change would allow facilities to
conduct studies to determine the toxicity of these metals in their discharge.
Although the proposed rule essentially states that the studies must be provided at
the time of application by the permittee, we understand that numerous comments
were received about that statement at the public meetings on the proposed rule
changes and that DWQ will consider removing "at the time of application" from

NPDES Permit Renewal Application
Page - 3
the proposed rule. The City of Shelby may conduct studies to support the
determination of the toxic form of metals, if metals are limited in our draft permit.
If you should have any questions during your review or need additional
information, please contact me at [phone] or Francine Durso, P.E., with
our Consulting Engineering Firm, Arcadis Geraghty & Miller, in their Raleigh
office at [phone].

SBELBY WATER TREATMENT PLANT
NPDES PERMIT NO. NCO027197
Narrative Description of the Sludge Management Plan for Filter Backwash
The Water Treatment Plant for the City of Shelby discharges its
filter backwash, alternating between one of two settling lagoons.
Alum sludge settles in the lagoon and the decant is discharged to
a nearby unnamed tributary discharging approximately two thousand
(2,000) feet to the First Broad River. Every other year, the
receiving lagoon is drained and the alum sludge in it is allowed to
dry. Typically, the sludge is allowed to dry for up to one year
before collected for disposal at the Cleveland County landfill.
While the sludge is drying in one lagoon, the other lagoon is
receiving the filter backwash.
