The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall
be performed as a Ceriodaphnia dubia 7-day. pass/fail test. The tests will be performed during the
months of January, April, July and October. These months signify the first month of each three
month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be
obtained during representative effluent discharge and shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGP3B. Additionally, DWR Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1 623 Mail Service Center

• an upflow clarification tank
• flash mix vault and flash mixer
• flocculation
• media filter backwash
• two (2) sedimentation basins
• two (2) media filters
• clearwell

Eli ig bility for Coverage under the General Permit NCG590000 — Lawrence T. Sprinkle, Jr. Water
Treatment Facility (WTF) is not eligible for the general permit because of the stream classification WS-II;
HQW, CA.
Toxici — With an IWC >0.25%, this permit requires Chronic Whole Effluent Toxicity (WET) testing
using Ceriodaphnia dubia to be performed as a 7-day pass/fail test at 90% effluent concentration, during
January, April, July and October [TGP3B]. The facility has passed 12 of the last quarterly toxicity tests
(Ju12012-Apr2015).
Renewal Summary — This permit reflects discharge at Outfall 001. DWR updated the following:
• added updates to facility map, outfall locations and parameter codes to Section A. (L)
• updated Total Residual Chlorine (TRC) limit to 17 µg/L because the outfall discharges to
unnamed tributary to Ivy Creek (River) with a 7Q 10/30Q2 that equals zero
• added monthly monitoring of Manganese with a Monthly Average Limit of 100 µg/L because a
reasonable potential analysis (RPA) of the facility's data indicated a reasonable potential to
exceed the Water System (WS-Il; HQW, CA) stream standard of 100 µg/L (HQW reduces water
quality standard to half Compliance with this limit shall commence on December 1, 2019,
approximately 48 months from the permit effective date
• added monthly effluent Turbidity monitoring
• removed upstream and downstream Turbidity monitoring
• removed Total Iron monitoring (see RPA information below)
• added Electronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]
• added Total Fluoride monitoring with the following footnote 6: Fluoride monitoring should apply
only if the facility backwashes with fluoridated, finished water.
Stream — Discharge from Lawrence T. Sprinkle, Jr. Water Treatment Facility (WTF) for Outfall 001 is
into an unnamed tributary to Ivy Creek (River) [Stream Segment 6-96-(11.3)]. The pervious permit had
incorrect information for the location of discharge to the wrong stream segment for Ivy Creek. In
addition, the correct stream classification is WS-II; HQW, CA. The classification of High Quality Waters
(HQW) now applies to this stream segment. The 7Q 10/30Q2 data for the unnamed tributary at the
location of the discharge is zero. Stream flow data for an unnamed tributary or effluent channel was
applied to the RPA. Flow information for the main body of Ivy Creek was used in the previous permit.
The segment is not currently listed as impaired on the 2014 North Carolina 303(d) List for fish tissue
Mercury and Fecal Coliform.
RPA — A Reasonable Potential Analysis (RPA) was conducted on Copper, Aluminum, Iron, Manganese and
Turbidity effluent parameters data because Discharge Monitoring Reports (DMRs) reported concentration
above method -detection levels (MDLs), [with the exception of Copper], for the past three (4) years and one
half (1/2) years (Jan2011-Jun2015) that discharge was reported. 7Q10/30Q2 data at the location of the
discharge is zero. Stream flow data for an unnamed tributary or effluent channel was applied to the RPA.
[See attached RPA summary sheets.]

Iron did not show reasonable potential to violate state WQS; since predicted maximum was less than
50%, no monitoring is required.
Manganese effluent data suggest reasonable potential to exceed its WQS standard of 100 µg /L (one
half of the water supply (WS) standard 200 µg /L is applied for HQW waters). Renewal will require
monthly monitoring of Manganese with a Monthly Average Limit of 100 µg /L. This limit will
become active four (4) years from the effective date.

My comments are:
Cover Draft Letter — third bullet in the parenthesis "(HQW reduces water quality to half)" reads wrong. I believe he is
missing the word "standard" after water quality. This error is also in the fact sheet under Renewal Summary third bullet
Fact Sheet — the Facility Information table last cell list the town as " Hills Hill, NC, this should read "Mars" Hill, NC.

Please provide your comments by October 23, 2015 [email OK]
RESPONSE:
I have reviewed the draft permit and determined that the proposed discharge is not located
sufficiently close to any existing or known proposed public water supply intake (_miles) so as
to create an adverse effect on water quality. The DWR concurs with the issuance of this permit
provided the Permittee properly operates and maintains the facility; the Permittee meets the stated
effluent limits prior to discharge; and the discharge does not contravene the designated water
quality standards.
X I concur with issuance of the above permit provided the following conditions are met:
The DWR concurs with the issuance of this permit provided the Permittee properly operates and
maintains the facility; the Permittee meets the stated effluent limits prior to discharge; and the
discharge does not contravene the designated water quality standards.
I oppose the issuance of the above permit based on reasons stated below, or attached:

Mr. Duncan,
I am reviewing the permit renewal application for NPDES permit NCO085154 Lawrence T. Sprinkle Jr. WTF and had a
question foryou. I'm not sure if you were aware of the general permit NCG590000 for greensand and conventional
WTPs, but appears from a preliminary review that you may be eligible for coverage. I have attached for your review a
copy of the general permit, technical Bulletin and the Pros and Cons of the general permit. Monitoring for you facility
would be found in condition B.(3). Conventional WTP Effluent Limitations and Monitoring Requirements— Discharging to
Freshwater.
Please let me know if you would like to have your Individual NPDES permit converted to the general permit NCG590000.
Sincerely,
Derek

The Town of Weaverville would like to ask for renewal of our NPDES permit # NC0085154.
The only changes that have been made to our system are as follows:
We installed new chlorine and PH analyzers that use less process water.

Page t of 3 Version 3/2014

NPDES PERMIT APPLICATION - SHORT FORM C - WTP
For discharges associated with water treatment plants
® Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by
filtration and disinfection)
❑ Ion Exchange (Sodium Cycle Cationic ion exchange)
❑ Green Sand Filter (No sodium recharge)
❑ Membrane Technology (RO, nanofiltration)
Check here if the treatment process also uses a water softener ❑
6. Description of source water(s) (Le. groundwater, surface water)
Surface Water (Ivy River)
7. Describe the treatment process(es) for the raw water:
Raw water is injected with Delpac 2020 (Aluminum Chloride Hydroxide Sulfate) and 12.5%
caustic (Sodium Hydroxide) before reaching our up -flow clarifier. Then it is injected again at the
start of our conventional treatment process at the flash mixer. Water then runs through settling
basins to dual media filters. At this point chlorine gas is injected for disinfection. Once filtered
we adjust PH with caustic and add a corrosion inhibitor (phosphate) then to our storage tank to
be pumped to town.
S. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Our 250,000 gal waste basin receives all of our process water and backwash water, this water is
injected with S02 (Sulfur Dioxide) to remove chlorine residual just before it enters the waste
basin. We also empty our settling basins into the waste basin biannually. The clarified water is

Lawrence T. Sprinkle Jr. Water Treatment Facility
Waste Water Sludge Management Plan
The Lawrence T. Sprinkle Jr. Water Treatment Facility is a 1.5 MGD municipal
water treatment facility. The facility incorporates the use of an up -flow clarifier
for pre-treatment of surface water. After clarifier treatment process is
conventional in design.
We have a 250,000 gal waste clarification basin for process and backwash water
collection and clarification. Clarified waste water is decanted via use of joined
pipe with winch depth control. Decant of waste waters are controlled by the
following procedures.
Waste waters collected in waste basin are allowed to settle to acceptable limits
set forth in NPDES permit #0085154 requirements. Settled water meeting
NPDES requirements are periodically removed by use of winch controlled
decant pipe. Sludge generated in process is pumped (as needed) by vertical
turbine pump into a licensed waste tanker and hauled to MSD of Buncombe
County for disposal. Disposal is in accordance with North Carolina General
Statues regulating waste disposal.
Daily average effluent is calculated by totaling all filter wash waters, calculated
process sample pump totals and basin volume if drained for cleaning. Typically
the effluent is estimated over a 7 day period. No effluent metering device is in
plac .
