Dear Mr. Wise:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge 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 May 9, 1994 (or as subsequently amended.) The following
modifications have been made to the permit:
• The effluent page for 0.750 MGD has been deleted, since the Granite Falls WWTP has been re -rated for a
design capacity of 0.900 MGD. All effluent limitations at the 0.900 MGD wasteflow are now in effect.
• The effluent limitation for lead will be dropped based on evaluation of ,the reasonable potential analysis.
Lead will be monitored quarterly at the same time as the chronic toxicity test.
• Effluent monitoring for zinc will be reduced from 2/month to quarterly based on evaluation of the reasonable
potential analysis.
• Discontinue instream monitoring for conductivity and fecal coliform based on revised DWQ procedure.
Instream monitoring for dissolved oxygen and temperature will be continued.
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. Part II, EA. addresses the requirements to be
followed in case of change in ownership or control of this discharge. 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.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (2). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
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, auarterlu 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 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 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 condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
The Town of Granite Falls has requested renewal of the Granite Falls WWTP. The WWTP
discharges into the lower portion of Gunpowder Creek, a class WS-IV CA stream, in CTB32
subbasin. The discharge is less than one mile upstream of Little Dam. Previous WLA in 1995
determined that the retention time in the impoundment was less than 14 days and it was not
necessary to assign nutrient limits to Granite Falls.
Gunpowder Creek is not listed on North Carolina's 2000 303(d) list. The use support rating
for Gunpowder Creek from source to 0.5 mile downstream of Caldwell Co. SR1127 is support
threatened. The major source is nonpoint. The biological assessment of Gunpowder Creek at
SR1002 in August 1997 was Good -Fair. The Lenoir -Gunpowder Creek WWTP is located
upstream of the Granite Falls outfall.
The facility was re -rated to a hydraulic design capacity of 0.900 MGD plant in 1995. The
current plant consists of an aerated grit chamber, self cleaning bar screen, influent Parshall
flume with continuous flow monitoring, parallel oxidation ditches, parallel peripheral feed
clarifiers, chorine contact basin with gas chlorination, dechlorination, cascade aeration, aerobic
disgester and sludge drying beds with polymer feed system.
Granite Falls currently has an inactive pretreatment program. There is one nonsignificant
industrial user discharging to the system.

2/month monitoring for zinc
Quarterly monitoring for TP and TN
Chronic Toxicity P/F @ 13%; March June September December
TOXICITY TESTING:
Current Requirement: Chronic Toxicity P/F @ 13%; March June September December
The Granite Falls WWTP has consistently passed the tox test since 1996. One no report in
Sept. 1996. All PASS since that time. Recommend renewal of existing tox test @ 13%.
COMPLIANCE SUMMARY:
Facility has maintained an excellent compliance record since 1997. There have been no NOVs
or exceedances of permitted limits. Granite Falls has passed all compliance evaluation
inspections.
Through Sept. 2000, Avg. Qw = 0. 458 MGD (approximately 51% of capacity), BOD5=6.77 mg/l,
NH3=4.28 mg/l, TSS=8.8 mg/1, TN=6.3 mg/ and TP=2.06 mg/l.
In 1999, Avg. Qw = 0.457 MGD (approximately 51% of capacity), BOD5=7.4 mg/l, NH3=2.78
mg/ 1, TSS=8.0 mg/ 1, TN=7.7 mg/ and TP=1.51 mg/ 1.
In 1998, Avg. Qw = 0.512 MGD (approximately 57% of capacity), BOD5=8.5 mg/1, NH3=4.47
mg/l, TSS=8.9 mg/l,' TN=10.1 mg/ and TP=2.18 mg/l.
In 1997, Avg. Qw = 0.487 MGD (approximately 54% of capacity), BOD5=7.0 mg/l, NH3=4.24
mg/l, TSS=9.2 mg/l, TN=12.7 mg/ and TP=3.5 mg/l.
INSTREAM MONITORING:
Instream Monitoring Requirements for DO, Temperature, Conductivity, and fecal coliform. A
review of data indicated that there were no instances of instream DO < 5 mg/1 or fecal coliform
> 200/ 100ml. Will recommend deletion of instream monitoring for fecal coliform and
conductivity. Instream monitoring for DO and temperature will be continued.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• Elimination of effluent page. for 0.750 MGD flow
• Deletion of instream monitoring for fecal coliform and conductivity per Division
procedure.
• 2/month monitoring for zinc reduced to quarterly based on reasonable potential
analysis of toxicants. This should coincide with quarterly toxicity monitoring
• Elimination of lead limit of 192 ug/1 based on reasonable potential analysis. Will
recommend quarterly monitoring for lead.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: 01/ 17/2000
Permit Scheduled to Issue: 03/04/2000
STATE CONTACT:
If you have any questions on any of the above information or on the attached permit, please

Town of Granite Falls
Sludge Management Plan
NPDES # NCO021890
Wastewater sludge from the Granite Falls Wastewater Treatment Plant 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. The sludge is allowed to settle and the supernaught is decanted
back to the head of the treatment plant. The thickened sludge will average 2% solids.
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 a hourly
basis. The pH of the digested sludge is checked after 24 hours to maintain 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 spread class B sludge at agronomic rates on permitted area farm
land under the provisions of Land Application Permit Number WQ0001618.
