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.
Changes for Renewal. The Division understands that you have made no significant changes in treatment
processes during the last permit cycle. We have therefore made only minimal changes to your permit by
updating your facility description and site map. However, please note that electronic reporting of
Discharge Monitoring Reports is now required within 270 days of the permit effective date.
Implementing Electronic Discharge Monitoring Reports (eDMRs). Please be advised that the Division

A. (2.) CHRONIC TOXICITY (QUARTERLY) - LIMITED
[G.S. 143-215.1(b)]
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, guarterlX monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina
Phase H 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 at 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 H Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1999)
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 condition will be entered on the Effluent Discharge Monitoring
Form (MR-1) for the months in which tests were performed, using the parameter code TGP313 for the pass/fail results and
TET313 for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent to the following address
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section/Aquatic Toxicology Branch 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
Resources 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.

Summary. The Town of Granite Falls has requested renewal of the Granite Falls W WTP. There are no
significant changes in facility operations since last renewal. The WWTP discharges into the I wer portion of
Gunpowder Creek less than one mile upstream of Little Dam. The City of Lenoir -Gunpowder Creek W WTP is
located upstream of the Granite Falls outfall.
Compliance. This facility received no NOVs during this permit cycle. A total of six (6) permit limit
exceedences (2014) were flagged by BIMS for BOD5 and TSS, but were noted by ARO as "reporting errors"
(no action BPJ), or for TRC flagged by BIMS erroneously below acceptable levels [50µg/L]. Although this
facility typically runs at —1/3 design capacity (0.900 MGD), data suggest significant impact by inflow and
infiltration (M as indicated by reported flow Max vs. Ave (see table). This facility has produced no
observed harmful impacts to receiving -stream water quality.

Receiving Stream Gunpowder Creek (11-55-4) is not listed on North Carolina's 303(d) list [EPA -
approved, 2014]. Its designated use is rated supporting for a 13.4-mile segment from.a point 0.5 mile
downstream of Caldwell Co. SR1127 to a point 0.8 miles downstream, of Billy Branch. Although heavy
sedimentation has resulted in some habitat degradation, a biological assessment at SR1718 in August
2002 was "Good -Fair." The receiving stream is not impaired or threatened except for the statewide
mercury fish -consumption advisory.
WHOLE EFFLUENT TOXICITY (WET) TESTING:
Current Requirement: Quarterly WET: Chronic P/F @ 13% during March, June, September, and
December. Although WET test is required only Quarterly, Granite Falls WWTP has consistently
reported -eight (8) tests per year. They have reported forty (40) tests since 2010 indicating "passed." No
permit changes recommended.

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. Supernaught
is decanted back to the head of the treatment facility. This process is repeated until the
withdrawal of a clear supernaught cannot 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 Land 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.
