Subject: Issuance of NPDES Permit
Permit No. NCO021890
Granite Falls WWTP
Caldwell County
Dear Mr. Wise:
In accordance with the application for discharge permit received, the Division is forwarding
herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North
'Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
This final permit authorizes the Town of Granite Falls to discharge municipal wastewater from
the Granite Falls Wastewater Treatment Plant to Gunpowder Creek, a class WS-IV CA water in
the Catawba River Basin. This permit includes discharge limitations/or monitoring for flow,
BOD5, ammonia nitrogen, total suspended solids, dissolved oxygen, fecal coli form, total
residual chlorine, total nitrogen, total phosphorus and chronic toxicity.
The following procedure has been recently implemented by DWQ:
• Total residual chlorine (TRC) compliance level changed to 50 ug/L. Effective March 1,
2008, the Division received EPA approval to allow a 50 ug/I TRC compliance level. This
change is due to analytical difficulties with TRC measurements. Facilities will still be
required to report actual results on their monthly discharge monitoring report (DMR)
submittals, but for compliance purposes, all TRC values below 50 ug/I will be treated, as
zero. A footnote regarding this change has been added to the,effluent limitations
pages in the permit.
If any parts, measurement frequencies or sampling requirements contained in this permit 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 in the form of a written
petition, conforming to Chapter.150B of the North Carolina General Statutes, and filed with the
office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714.
Unless such a demand is made, this permit shall be final and binding.

Please take notice that this permit is not transferable. The Division may require modification
revocation and reissuance of the permit. This permit does not affect the legal requirements to
obtain other permits which may be required by the Division of Water Quality or permits required
by the Division of Land Resources, Coastal Area Management Act, or any other Federal or Local
governmental permits may be required.

A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) - 0.9 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 13%.
The permit holder shall perform at a minimum, quarterl monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions.'The tests will be performed during the months of March, June, September and
December. Effluent sampling for`this testing shall be performed art the NPDES permitted final'effluent discharge
below all treatment processes.
If the test procedure performed as the first test of any single.quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required"as part of this permit dondition will be entered on'the Effluent Discharge' :
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP36 for the
pass/fail results,and THP36 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 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, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. 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 a month in which toxicity monitoring is required, 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 the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required.during the following month.
Should any test data from this monitoring requirement 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.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, 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.

Can you give me an idea on how much in advance of the expiration date you need the information? These are all Dana's
towns and we may have to assign some out to other staff if you need a quick turnaround.
FYI: Clarmount went inactive 6/2007; Crammerton went inactive 5/2007; Cherryville went inactive 8/2001; Granite Falls
went inactive 1/1993. Taylorsville never became an active program.

Town of Granite Falls
Wastewater Treatment Plant
Sludge Management Plant
NPDES Permit Number NCO021890
Settled wastewater sludge from secondary clarifiers is wasted into a 500,000 gallon aerobic
digester where the sludge is digested for a minimum of 85 days to a maximum of 180 days.
Aeration of the aerobic digester is shut off and the sludge is allowed to settle. Supemaught
is decanted back to the head of the treatment facility. This process is repeated until the
withdrawal of a clear supernaught can not be achieved. The thicken sludge will average 2%
solids and is ready for chemical addition.
To meet the pathogen and vector requirement prior to land application the digested sludge
is lime stabilized to raise the pH of the sludge to 12.0 or more and is monitored on an hourly
basis. The pH of the digested sludge is checked after 24 hours and maintained at a pH of 11.5
or above. Additional lime is added if necessary.
The Town of Granite Falls contracts with a Sludge Management Biosolids Application
Company to haul and surface spread class B biosolids at agronomic rates on permitted area farm
land including sludge, soil and plant sampling and analysis along with annual reporting as
required under the provisions of Land Application Permit Number WQ0001618.
