Facility Information
Applicant/Facility Name:
Greater Badin WWTP
Applicant Address:
201 South Second Street
Facility Address:
18 Sewer Plant Road
Permitted Flow
0.550 MGD
Type of Waste:
100% Domestic Waste plus unknown flow of Landfill leachate
Facility/Permit Status:
Renewal
County:
Stanl
BACKGROUND
The Greater Badin WWTP is a Class III facility with a current permitted flow of 0.550 MGD. The facility
services the Town of Badin with a population of 625. The Greater Badin WWTP influent wastewater is
100% domestic in nature. On November 28, 2005 Alcoa started discharging landfill leachate from a
closed, capped MSW located on Alcoa property into the collection system '/2 mile from the facility on
Wood Street with intermittent flows of up to 7500
RECEIVING STREAM INFORMATION
This facility discharges to Little Mountain Creek in sub basin 03-07-08 of the Yadkin Pee -Dee River Basin.
The Little Mountain Creek is classified as WS-IV waters at the point of discharge. The discharge is located
0.5 miles upstream of Stanly County SR 1545.
Little Mountain Creek is listed on the 2006 303(d) list as impaired for biological integrity, with an unknown
source for the impairment.
PERMIT LIMITS
Existing limits for Flow, BOD, TSS, NH3, fecal coliform, TRC and pH will be retained in the 2009 permit
renewal. No changes to these conventional parameters.
INSTREAM MONITORING
Instream monitoring is waived in light of the facility participation in the Yadkin Pee -Dee Monitoring
Association. Instream monitoring will be immediately reinstated should facility end its participation in the
Association.

ACCEPTANCE OF ALCOA WASTEWATER
• 2-24-04 MRO meeting with DWQ reps, Stanly County and Alcoa. Various options for handling the
LF seepage were discussed, and a resolution was reached.
o 1t was decided to allow Alcoa to connect to the"WWTP collection system -and discharge
the LF seepage for treatment. No pretreatment program was required at this time but this
could change in the future if problems result from the connection. I Monitoring
requirements for FI and CN were added to the 2004 permit renewal as well as' WET
monitoring as recommended by Matt Matthews at ATU. The need for limits can be .
determined at the next permit renewal or sooner if WET tests show a need.
• 4-8-04 Alcoa letter to WWTP _
o "The composition of the waste streams placed in the LF by,Alcoa and the Town of Badin
is not known. The industrial„wastes could possibly include wood,, paper, metal, carbon
dust, small amounts of spent' pot lining; spent carbon anodes waste aluminum oxide bath
and debris containing, asbestos. Spent pot lining is generated during primary aluminum
reduction and is currently listed as a hazardous waste. However, as an overly
conservative measure, Alcoa is considering' this water to potentially contain a listed
hazardous waste. As such Alcoa is .required to provide notification in writing'of its intent
to discharge this material to the POTW under 40 CFR 403.12(p)(1). A review. of data
collected from the wastewater during . the past five years indicate that the water can
contain cyanide at concentrations ranging from no -detect to. 0.061 •mg/L and- fluoride .
concentrations from 11 mg/L to 27 mg/L. The historic. wastewater flows have averaged
approximately 4 gpm with a maximum of.15 gpm. This could possibly result in a mass,
loading of the following hazardous constituents:
Potential Avg monthly loadin Ibs
Potential Avg 12 month loadin ' Ibs
Cyanide
0.08
0.95
Fluoride
35'
' 420
• 2-2-09 - The above mentioned letter was sent to Alcoa more than a month after a decision was
made to allow the WWTP to accept this waste stream. Based on the above mentioned letter
notification and a telephone conversation this permit writer had with Alcoa on 2-2-09 in which
Alcoa stated, "Nothing but MSW was put into the Alcoa=Badin LF,", I have added additional
monitoring requirements and required that 3 PPA's be conducted during this permit cycle.
In addition the receiving stream is listed as impaired waters as well as WS-IV. These additional measures
should give the WWTP and the DWQ a better understanding of the amount and nature of these unknown
and potentially hazardous waste streams.
COMPLIANCE REVIEW:
o SOC WQ S03-010 On July 25, 2005 the facility entered, into SOC WQ S03-010 which relaxed the.
flow limits from 0.550 MGD to 1.2 MGD. The facility was exceeding the permitted flow limit of
0.550 mgd due to reported I&'I problems in the collection system. The SOC allowed the. WWTP to
eliminate I&I problems in the collection system. The SOC also allowed the connection of 7500
GPD of LF leachate, generated from Alcoa's LF.
o During the active SOC the facility paid $7064 in civil penalties for Ammonia and Flow violations.
The SOC expired on May 1, 2006.
Violations between 9-2005 and 2-2009 include:
➢ 9-05 Ammonia Nitrogen - $1078.95 - Ammonia Violations.
➢ 4-06 Ammonia Nitrogen - $1580.15 - Ammonia Violations
➢ 5-06 Ammonia 'Nitrogen - $1330.15 —Ammonia Violations
➢ 9-06 Ammonia Nitrogen - $1331.15 —Ammonia Violations
➢ 10-06 Ammonia Nitrogen - $1581.15 — Ammonia Violations
➢ 11-06 Flow Violations - $81.50 enforcement costs

recommended that the permit be renewed as requested. According to plant operators the
volume of landfill leachate being received from the Alcoa landfill site is significantly
higher than had been indicated in initial conversations and discussions about accepting
the material. I have enclosed some detail of the volumes received from the landfill. The
landfill was inspected at the time of the site visit. It was sufficiently capped and well
maintained. The SOC issued March 9, 2009 indicated that 7,500 gallons would be
received from the landfill. MRO requestpdraNcopies of correspondence associated with
the approval of the lea c ge to e W WTP be supplied to this office.

Re: Startup of Alcoa/Badin Landfill Seep Discharge to the Stanly County POTW
Dear Ms. Davis:
As you are aware, Alcoa Badin Works Plant ("Alcoa") has requested Stanly County POTW
to accept a continuous flow of approximately four gallons per minute from the Alcoa/Badin
landfill. Alcoa has received an acknowledgement from you that this discharge is permitted
in your May 10, 2005 correspondence. In this correspondence you requested that
notification of the anticipated schedule for starting the discharge be provided. This letter is
intended to notify you that Alcoa would like to start the discharge on November 18, 2005, or
shortly thereafter.
Alcoa requests an acknowledgment that starting this discharge on or after November 18,
2005 is permitted. Your assistance and help with this matter is greatly appreciated. Should
you have any questions concerning this notification and request, please call me at 865-977-

The Uwharrie River watershed is not included in this HUC. Near this boundary and included in this HUC
is the Mountain Creek watershed that flows south of Morrow Mountain and enters the Pee Dee River from
the west. This area includes the municipalities of Albemarle (in part) and Norwood. The principle
impoundment on the Pee Dee River in this part of the HUC, is Lake Tillery. East and north of this area
(formerly subbasin 030715) is the Little River and its tributaries. The Little River itself is a tributary of the
Pee Dee River. A large portion of this area of the HUC is located within the Uwharrie National Forest.
The land is mostly forested, but with some areas utilized for agriculture and silviculture. The town of Troy
is the largest urban area in this northeastern part of HUC 03040104. The Carolina Slate Belt
subecoregion dominates the northern part of the HUC. This subecoregion has some of the lowest water
yielding geology in the state resulting in the tendency of streams to dry up in summer.
Just south of this area is an approximately 50 mile long and 10 mile wide band of Triassic geology that
runs southwest to northeast. Streams in the Triassic subecoregion have low base flows and also tend to
stop flowing in summer months. This area consists of the portion of the Pee Dee River and its tributaries
from the Rocky River confluence to the dam at Blewett Falls Lake. Land use here is primarily a
combination of forest and agriculture with smaller towns like Polkton and Ansonville. The town of
Wadesboro is partially contained within this area. Clarks Creek is contained within a narrow portion of
Carolina Slate Belt geology that exists in the extreme southeastern part of this HUC.
The Pee Dee River has many permitted dischargers. However, contained within this HUC are less than
10 permitted facilities, none of which are listed as Major dischargers. Several of these are located within
watersheds where biological samples were collected for this report. These include Greater Badin WWTP
(NC 0074756), discharging up to 0.55 MGD to Little Mountain Creek; Mount Gilead Town WWTP (NC
0021105), 0.85 MGD to Clarks Creek; and Montgomery County WTP (0080322), 0.47 MGD to UT Clarks
Creek. Three facilities are located within the Little River Watershed. These are Biscoe Town WWTP. (NC .. - .
0021504) discharging up to 0.6 MGD to Hickory Branch; Carolina Trace Utilities Inc. (NC 0038831),.0:325
MGD to the Upper Little River; and Troy Town WWTP (NC 0028916), 0.84 MGD to Densons Creek: tc t+ i
One discharger, Ansonville Town WWTP (NC 008125), discharges up to 0.12 MGD directly to the'P6e_"..- . %,
Dee River. Another facility, Stony Gap Fish House (NC 0040801) has ceased discharging up to 0.004
MGD to UT Jacobs Creek before January 2007.
Overview of Water Quality
A total of 18 biological monitoring sites were sampled within HUC 03040104 for basinwide assessment of
water quality (Table 4). Of those sites, nine rated Excellent, five Good and two Good -Fair. Two sites
were Fair. No sites rated Poor in either 2004 or 2006. The two Fair streams, Little Mountain Creek and
Cedar Creek are both affected by naturally low flows typically seen in both Carolina Slate Belt and
Triassic Basin ecoregions. Flows in Little Mountain Creek however appear unable to dilute effluent from
the upstream Badin WWTP. No anthropogenic influences could be detected that contributed to the
naturally low flows at Cedar Creek to cause it to be in an biologically degraded condition.
Water quality in HUC 03040104 appears to be stable between the 2001 to 2006 samplings (Table 4). Of
the six benthic sites sampled in 2006, three improved in bioclassification (Little River at NC 731, Mountain
Creek at SR 1150 and Clarks Creek at SR 1110); one site declined (West Fork Little River at SR 1311);
and two sites remained the same (Little River at SR 1340 and Little Mountain Creek at SR 1720).
There were12 fish sites sampled in 2006 (or in 2004 as special studies). Compared with the 2001
basinwide sampling effort: four improved in bioclassification (Little River at SR 1127, Bridges Creek at
SR 1519, Mountain Creek at SR 1720 and Mountain Creek at SR 1150); three declined (Brown Creek at
SR 1230, Cedar Creek at SR 1709 and Cheek Creek at SR 1541); and four remained the same (West
Fork Little River at SR 1311, Rocky Creek at SR 1549, Clarks Creek at SR 1110 and Cheek Creek at SR
1563). One site, Densons Creek at SR 1323 was only sampled once (in 2004).

Taxonomic Analysis
The number of EPT taxa collected has remained stable since the first collection in 1996. Though the 2006 collection included two new taxa for this site
(intolerant caddisf ies Po/ycenfropus and Diplectrona modeste ), these taxa were rare in abundance. One intolerant stonefly (Eccoptum xanthenes )
was also collected though it too was rare. Abundant taxa at the site (the caddisf ies Cheumatopsyche and Hydropsyche bettem, the omnipresent
mayfly Maccaffertium modestum and the snail Elimia) were highly tolerant with the exception of intolerant Elimia. A midge, Dicrotendipes
noemodestus, a species indicative of organic enrichment, was present in abundance.
Data Analysis
Approximately 1.5 miles downstream of the Badin W WTP, Little Mountain Creek exhibits the intermittent flow characteristic of slate belt streams. Low
vows during the summer months fail to dilute the the effluent from the W WTP resulting in elevated specific conductance. An increase in the EPT BI is
most likely due to lower abundances of EPT collected in 2006 as compared to 2001 (43 and 70, respectively). It is probable that low flows and organic
enrichment are prohibiting an improvement in water quality as habitat was not restrictive.

Dear Mr. White,
MEp0.EAT 5Eyy4
The Greater Badin Wastewater Treatment Plant is ready to begin receiving flow from the
AlcoaBadin landfill. This discharge from the landfill was specifically acknowledged by the
North Carolina Department of Environment and Natural Resources Division of Water Quality in
the NPDES Permit NCO074756 issued March 22, 2004 and effective May 1, 2004. As a result of
the preliminary analysis of the seepage from the AlcoaBadin landfill, monitoring for fluoride,
cyanide and toxicity have been added to the routine testing required by permit. However, the
permit writers saw no need to require a pre-treatment program for this by-product Further, it
was explained to both parties that should the need arise in the future due the quality of the
effluent from the landfill, the POTW would become subject to a pre-treatment program at that
time.
I have enclosed for your review a copy of the NPDES permit NC0074756. If you have any
questions related this matter, please contact our offices at [phone].
Sincerely yours,
Donna L Davis

Re: Alcoa/Badin Landfill Seep Possible Waste Classification and Notification
Alcoa Badin Works, Badin, NC
Dear Ms Davis:
As you are aware, the Alcoa Badin Works Plant ("Alcoa") has requested that the Stanly County POTW
(the "POTW") in Badin, North Carolina accept a continuous flow of approximately four gallons per
minute ("gpm") of collected seep water from the Alcoa/Badin landfill. The town of Badin and Alcoa used
this landfill for 70 years to manage municipal and industrial solid waste. The composition of the waste
streams placed in the landfill by the town of Badin and Alcoa is not known. It is expected that typical
municipal refused generated by the town and undetermined amounts of industrial solid waste from Alcoa
Badin Works were managed at this landfill. The industrial wastes could possibly include wood, paper,
metal, carbon dust, small amounts of spent pot lining, spent carbon anodes, waste aluminum oxide bath,
and debris containing asbestos.
Spent pot lining (SPL) is generated during primary aluminum reduction and is currently listed as a
hazardous waste, K088. If SPL were in the landfill, leachate impacted by the SPL would be a "derived
from" hazardous waste. While the cyanide and fluoride observed in the Alcoa/Badin landfill seep are
constituents associated with SPL, the concentrations measured in the seep could be caused by other
sources, such as pot insulation, bath, and other non -hazardous waste materials. The historical measured
concentration of fluoride and cyanide in the seep are not indicative of what is typically measured at
known SPL landfills. However, as an overly conservative measure, Alcoa is considering this water to
potentially contain a listed hazardous waste.
As such Alcoa is required to provide notification in writing of its intent to discharge this material to the
POTW under 40 CFR 403.12(p)(1), which states:
The Industrial User shall notify the POTW, the EPA Regional Waste Management Division Director, and
State hazardous waste authorities in writing of any discharge into the POTW of a substance, which, if
otherwise disposed of, would be a hazardous waste under 40 CFR part 261. Such notification must
include the name of the hazardous waste as set forth in 40 CFR part 261, the EPA hazardous waste
number, and the type of discharge (continuous, batch, or other). If the Industrial User discharges more
than 100 kilograms ofsuch waste per calendar month to the POTW, the notification shall also contain the
following information to the extent such information is known and readily available to the Industrial

Ms. Donna Davis
Director of Utilities

Page 2 of 7
User: An identification of the hazardous constituents contained in the wastes, an estimation of the mass
and concentration of such constituents in the ivastestream discharged during that calendar month, and an
estimation of the mass of constituents in the. wastestream expected to be discharged during the following
twelve months. All notifications must take,.place within 180 days of the effective date of this rule.
Industrial users who commence discharging after the. effective date of this rule shall provide the
notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any
notification under this paragraph need be submitted only once for each hazardous waste discharged.
However, notifications of changed discharges must be submitted under 40 CFR 403.12 6). The
notification requirement in this section does not apply to" pollutants already reported under the self -
monitoring requirements of 40 CFR 403:12 (l), (d), and (e).
The above -referenced information for the subject discharge previously has been provided to you in earlier
correspondence. Nevertheless, this letter presents the information in one explicit notification as required
by 40 CFR 403.12(p)(1). The wastewater steam is primarily comprised of groundwater seepage coming
from the area of the Alcoa/Badin Landfill. Table 1 summarizes the analytical results of a recent
wastewater. sample collected on'March. 27, 2003. Table 2 and 3 summarize the cyanide and fluoride data,
respectively, collected from the landfill seep,.since 1998.
A review of data collected from the wastewater during the past five years indicate that the water can..
contain cyanide at concentrations ranging from non -detect to 0.061 mg/L and fluoride in concentrations
from 11 mg/L to 27 mg/L. The historical wastewater flows have averaged approximately 4 gallons per
minute (gpm) with a maximum of 15 gpm. '.`;The higher flow rates and concentrations of cyanide were
observed prior to the closure and capping oftle landfill. This could potentially result in a mass loading of
the following hazardous constituents:

This letter requests on behalf of Stanly County Utilities / Greater Badin Water and Sewer District,
renewal of the National Pollutant Discharge Elimination System permit NCO074756 for the Greater Badin

efforts have been made to ensure effective operation and maintenance of the facility with a goal of
producing environmentally beneficial or benign treatment by-products and to comply with local, state and
federal regulations.
Included with this letter of request are a completed application form and a narrative description of the
Stanly County Utilities / Greater Badin Water and Sewer District sludge management plan.
Stanly County Utilities and Greater Badin want to thank you for your consideration of this matter.
Sincerely,
Donna Davis, Director

Sludge Management Plan
The Greater Badin Wastewater Treatment Plant provides treatment of domestic
wastewater for the Greater Badin Water and Sewer District located in Stanly County,
North Carolina. The facility treats an average 232,000 gallons of wastewater daily and
serves a population of approximately 1400 residents. The plant generates from its
wastewater treatment processes between 25 and 30 dry tons of sludge annually. The
sludge is dried on site and hauled to Uwharrie Environmental, a landfill receiving site in
Montgomery County, North Carolina. Sludge is added to the Badin facility drying beds
periodically and hauled to the landfill only once per year.
