Subject: Draft NPDES Permit
Permit NC0088781
Bladen Bluffs Regional Surface Water WTP
Bladen County
Dear Mr. Betz:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft carefully to ensure
thorough understanding of the conditions and requirements it contains.
We strongly request that the recycle alternate be further evaluated as an alternative to direct discharge. Public Water
Supply might not promote this practice, but they certainly do allow it. There are several drinking water treatment
facilities in North Carolina that do recycle filter backwash water after appropriate treatment. The City of Raleigh's E.
M. Johnson WTP has not discharged since August of 2006. Public Water Supply has the authority to require discharge
periodically if buildup of hazardous substances, such as cysts of parasites, may be occurring.
Please note that in conformance with. the Division's Permitting Strategy for drinking water treatment plants, quarterly
Whole Effluent Toxicity (WET) testing is required, as well as monitoring for several metals that are pollutants of
concern. The WET test is an acute toxicity test with fathead minnows (Pimephales promelas) at 90%, monitoring only.
Concurrent with this notification, the Division is publishing a notice in newspapers having circulation in the general Bladen
County area, soliciting public comment on this permit draft. Please provide any comments you may have regarding this
draft to DENR — DWQ, NPDES Program no later than 30 days after receiving this draft permit. Comments should be sent
to the address listed at the bottom of this page. If no adverse comments are received from the public or from you, this permit
will likely be issued in February 2009 with an effective date of March 1, 2009.
If you have any questions or comments concerning this draft permit, contact me at the telephone number listed below.
Sincerely,
Jim McKay

NOTES:
1. The Division shall consider all effluent TRC values reported below 50 ug/1 to be in compliance
with the permit. However, the Permittee shall continue to record and submit all values reported by
a North Carolina certified laboratory (including field certified), even if these values fall below 50
ug/1.
2. pH shall not be less than 6.0 nor greater than 9.0 S.U.
3. IN means Total Nitrogen. For a given wastewater sample, TN is the sum of Total Kjeldahl
Nitrogen and Nitrate -Nitrite Nitrogen: TN = TKN + NO3-N + NO2-N.
4. Acute Toxicity (Fathead Minnow) Monitoring at 90%: February, May, August, and November [see
Special Condition A.(2)). Quarterly metals monitoring shall coincide with quarterly toxicity
monitoring.
All samples collected should be representative of the discharge.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
There shall be no discharge of waste or chemicals that do not directly result from the responsible
treatment of raw water.
Permit NC0088781
A.(2.) ACUTE TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct acute toxicity tests on a quarterlq basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity
In A Single Effluent Concentration" (Revised -July, 1992 or subsequent versions). The monitoring shall
be performed as a Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent
concentration at which there may be at no time significant acute mortality is 90% (defined as
treatment two in the procedure document). Effluent samples for self -monitoring purposes must be
obtained during representative effluent discharge below all waste treatment. The tests will be
performed during the months of February, May, August and November.
The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of
this permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DWQ Form AT-2 (original) is to be
sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical
measurements performed in association with the toxicity tests, as well as all dose/response data.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is
employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during any month, the permittee will complete
the information located at the top of the aquatic toxicity (AT) test form indicating the facility name,
permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Section at the address cited above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may
be re -opened and modified to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation & reporting of the data submitted on the DMR &
all AT Form submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test and
- will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

SUMMARY
- Residents and businesses in the four county area around Tar Heel depend on wells
for water. The Lower Cape Fear Water and Sewer Authority has been organized to
provide .drinking and industrial water for the region. The authority will offer water
_services to local governments and industrial users in Bladen, Columbus, Robeson and
Sampson counties. They propose to build a surface water treatment plant using
conventional water treatment processes. The plant will initially produce 4 MGD of
drinking water, expandable to 30 MGD by adding facilities. 4.4 to 6 MGD will -be
• withdrawn from the Lower Cape Fear River to feed the plant, and stored in an
inipoundment with capacity of 12 to 20 million gallons. The water will flow through -
two rapid mix chambers where ferric or alum coagulant, polymer and caustic are
added. From the rapid mix chambers the water will go through two trains of four -
stage flocculators, then to two sedimentation basins where solids will settle out. The
-- water will then be filtered by three filters of sand and granular activated charcoal or
• anthracite coal media. Chlorine, caustic and polymer can be fed before the filters.
• The water .will be pumped to a transmission line main located in the right of way of
• NC 87 where it will be made available to. existing local water distribution systems.
The Cape Fear River at the proposed intake location is classified as C waters at the
present. A request for reclassification to WSIV, CA has been submitted, but has not
been finalized at this time.

Wastewater
Two residuals basins will receive the sedimentation sludge, washwater from the
sedimentation basins, and filter backwash water. The solids will be allowed to settle,
then clear water will be decanted to a ditch draining back to the Cape Fear River. The
plant will have the option of pumping the decant water back to the raw water
impound. Dechlorination of discharged water will be by thiosulfate addition.
Basinwide Plan
The Lower Cape Fear River between lock and dam 3 and lock and dam 1 is not
impaired. The basinwide plan suggests stringent limits for oxygen consuming wastes.
Water Treatment Plants are not considered dischargers of oxygen consuming waste,
so no limits are imposed on this permit.
Permit Development
The Division's Permitting Strategy for Conventional Water Treatment facilities was
followed in developing monitoring requirements. There are no more stringent
requirements in the Basinwide Plan. The IWC is 0.18%, so an acute WET test at 90%
has been specified quarterly using fathead minnows as monitoring only. The
Basinwide expiration date for sub basin 03-06-16 is October 31, 2011. This will give
a permit life of approximately 2.5 years. The facility may not be completed at that
time, but it has been decided to maintain the scheduled expiration date.
