Town of Biscoe Wastewater Treatment Facility
NPDES Permit No. NC0021504
Montgomery County
Dear Mayor Criscoe,
Enclosed you will find a copy of the Compliance Evaluation Inspection report for the
inspection that was performed on February 27, 2013 at the Town of Biscoe Wastewater
Treatment Plant, accompanied by Sam Stewart (WWTP ORC). As part of this inspection, a tour
of the wastewater treatment plant was conducted. All observations and recommendations are in
Section D. Summary of Findings/Comments. On the day of this Compliance Evaluation
Inspection, the facility was found to be in minimal compliance with NPDES permit NC0021504.
Due by April 30, 2013, please send this Office a written response to all seventeen items
(summarized below, and discussed later in this CEI report). For the IWS requested information
listed in #7, 8, 9, 10, and #11 below, please send me the status of the IWS by April 30; in
addition, please send me the completed IWS information to this Office due by June 14, 2013.
1) Please continue smoke testing and TV inspections of the municipal sewer system.
2) . Please consider installing valves (gate valves?) at the influent splitter box.
3) Please perform the following items when reporting results for the Residual Chlorine on
the DMR:
A. Report the "less than" value as "< 10 µg/L" in the residual chlorine cell of the DMR,
when the chlorine test result is below 10'µg/L. This is said because the lowest calibration
verification standard in Biscoe's most recent annual 5-standard chlorine curve was 10
µg/L, which was performed on December 13, 2011. Presently, the ORC is routinely
reporting chlorine as < .5 on the discharge Monitoring Reports (DMRs), but this would
indicate that the chlorine analyses resulted in "less than 500 µg/L" or 0.5 mg/L. For
chlorine results that are greater than 10. µg/L, please report the actual results of the
Residual Chlorine on the monthly DMR submittals. (Please see the May 1, 2008

memo/letter to the NPDES Permittees that was sent from Matt Matthews, Supervisor,
Point Source Branch). For your convenience, the memo is enclosed with this CEI report.
B. Please put a check mark for the appropriate Residual Chlorine units (either as mg/L, or as
µg/L, as noted at the top of the Residual Chlorine column on the DMR).
C. Please do not report "0" as the residual chlorine on the DMR, as was reported during
June and July of 2012.
4) Please repair or replace scum/solids baffles in the aeration basins.
5) Please send me the Biscoe collection system educational program information for grease
control and for grease trap maintenance that Biscoe distributes to its collection system
customers as an aid to help educate them about not discarding oil and grease into the
sanitary sewer collection system.
6) Please send me a list of the areas of Town and the names of the businesses that have had
Fats, Oils and Grease (FOG) enforcement or have had increased sanitary sewer collection
system obstruction due to observed FOG problems.
7) Please perform an updated and current Industrial Waste Survey (IWS) Short Form for all
industries that discharge into the Town of Biscoe collection system (except for the three
industries listed in #8 below that will need to complete the IWS long form --- an 18 page
form).
8) Please send each of the following three industries the Industrial Waste Survey (long
form), enclosed with this CEI report: a) Telfa Corp., b) the metal fabricator (machine
shop/job shop) that is located on Sedbery Road, close to the Biscoe POTW, and c) Grede
(formerly Citation).
9) Please send me a list of all of the industries that you sent the IWS.
10) Please send me the list of all of the industries that completed the IWS and returned the
completed IWS to you.
11) Please send me a copy of all of the IWS's that you received.
12) . Please maintain a chlorine contact chamber sludge depth of less than one foot of sludge
blanket at all locations within the chlorine contact chamber.
13) Please physically remove the accumulated floating grease particles from the chlorine
contact chamber.
14) Please employ Best Management Practices in the collection system for minimizing grease
in the wastewater Influent. This may help in preventing floating grease particles from
entering the chlorine contact chamber and flowing to the Effluent bulkhead.
15) Please consider installing additional bulkheads in the Chlorine Contact Chamber to aid in
capture and removal of grease particles floating in the Chlorine Contact Chamber.
16) Please replace the pH 10 buffer that expired on May 2010.
17) Please perform an annual 5-standard chlorine curve as soon as possible. Please notice
that the last curve (performed on December 13, 2011 did not meet the % recovery criteria
for the 10 µg/L standard. (A computer instruction sheet for using the NCDENR DWQ
Laboratory website for determining an acceptable chlorine 5-standard curve is enclosed
with this CEI report).
With Mr. Stewart's assistance, we reviewed the present status of the items that were
listed in Paul Rawls' CEI inspection report (dated June 13, 2011), in which Mr. Rawls advised
should be acted upon as appropriate:

Mayor Criscoe
March 21, 2013
Page 3 of 5
1. Flow Monitoring. A review of Discharge Monitoring Reports (DMRs) for the period
February 2010 to March 2011 revealed flow values ranging from a low of approximately
0.126 MGD to a high of 0.587 MGD. Your current flow limit has been set at 0.500 MGD.
As discussed with Mr. Stewart flow data can reveal the presence of Infiltration/Inflow
(UI). Significant I/I can lead to increased operation and maintenance cost, increased
power consumption, sanitary sewer overflows (SSOs) and violation of NPDES permit
limits. You are urged to begin smoke testing and where possible TV inspections of the
municipal sewer system if not currently ongoing.
PRESENT STATUS: the smoke
testing is 50% complete, and the Town engineers are determining the priority of the lines
that need TV inspections.
2. Influent Splitter Box. As in the past it was noted that the influent structure of the
WWTF does not equally split influent flow to the two aeration basins. The Town is urged
to investigate this and act as necessary.
PRESENT STATUS there has been
improvement by utilizing a wider board and placing one on the bottom.
3. Grit Removal. The current WWTF is not equipped with influent grit removal. It is
recommended that the Town evaluate the installation of grit removal equipment. Failure
to install or maintain grit removal units can lead to the aeration basin filling with sand
and other settleable debris that can affect the overall operation of the facility. Further,
large quantities of grit can cause excessive pump wear and maintenance costs.
PRESENT STATUS: No Change
4. Clarifier. The current WWTF has only one clarifier. With the suspected I/1 issue noted
above the fact that the WWTF has only one secondary clarifier is very important.
Changes in flow rates to at or beyond the facility capacity can cause losses of solids and
can potentially lead to noncompliance. PRESENT STATUS: No Change
5. Chlorine Contact Chamber. It was noted that the sludge depth in the chlorine contact
chamber was approximately eighteen inches (18") deep. It is recommended that solids be
removed whenever solids level has reached in excess on one foot.
PRESENT STATUS:
According to the ORC, the sludge blanket depth averages 2-feet in the chlorine contact
chamber (which is 4 feet deep).
6. Sludge Drying Beds. It was noted that the sludge drying beds were partially covered
with vegetation. It is recommended that the noted vegetation be manually removed as
soon as possible. Please remember that the acceptance of grease onto sand drying beds
can lead to clogged drains
PRESENT STATUS: Three of the beds were full, and the
fourth drying bed had grease that was taken from a lift station.
7. Data Validation. A review of selected Discharge Monitoring Reports (DMRs) revealed
no issues.
8. Field Analysis. Please continue to perform field analysis for parameters covered under
Certificate No. 5204. This includes proper calibration and record keeping.
9. Influent Sampling. It was noted during the inspection that the Town does not currently
take influent samples utilizing the composite technique. The Town is asked to review the
current NPDES permit with regards to influent monitoring and provide to this office on
or before July 18, 2010 (2011) a plan of action to address this matter.

Mayor Criscoe
March 21, 2013
Page 4 of 5
PRESENT STATUS: Completed, a new portable 24-hour composite sampler has been
purchased and is in use at the Influent.
10. Scum/Solids Baffles in Aeration Basins. Scum/Solids Baffles in aeration basins were
observed to be corroded to the point that you can see through them in several locations.
The Town should investigate repair or replacement of these baffles.
PRESENT STATUS: No Change.
On the day of this inspection (February 27, 2013), the Effluent appeared to have
excessive solids and the color of Hickory Branch changed as the Effluent converged into this
receiving stream (please see the photographs that are included with this report). The ORC said
that the Effluent turbidity was due to recent rain events. The December 18, 2012 24-hour
composite sample Total Suspended Solids (TSS) result was 54 mg/L. This violated the TSS
weekly average permit limit of 45 mg/L. The ORC again thought that heavy rains had
contributed to the TSS violation. As a consequence of rain events, TSS violations appear to be
due to excessive Inflow and Infiltration .(I&I) in the Town of Biscoe sanitary sewer collection
system. Please see Item #1, listed above.
This wastewater treatment plant did not have valves to divert flow from one aeration unit
to the other, or that was capable of stopping the flow of wastewater from the aeration units to the
clarifier. In my opinion, this contributed to the difficulty of operating this POTW, and to the
difficulty of performing maintenance on an aeration basin or clarifier. As a suggestion, valves
located between the aeration basins and the clarifier could aid with investigating and removing a
partial blockage in the clarifier return activated sludge (RAS) line. As was noted during the CEI,
the POTW was presently experiencing trouble with the RAS line because it was partly obstructed
by a jetting tool and by another, but unknown, partial obstruction.
I observed an excessive amount of what appeared to be grease particles floating in the
clarifier weir trough and on a large portion of the surface of the chlorine contact chamber (please
see the photographs enclosed with this report). Fortunately, there did not appear to be grease
particles in the Effluent receiving stream (Hickory Branch). Please send me the Biscoe collection
system educational program information for grease control and for grease traps that Biscoe sent as
an aid to help educate its collection system customers.
Please perform an Industrial Waste Survey (IWS) for all industries that discharge into the
Town of Biscoe collection system. As according to the NPDES Permit, Part IV, Section C, 2, c.:
"The Permittee shall investigate the source of all discharges into the WWTP, including slug loads
and other unusual discharges, which have the potential to adversely impact the permittee's
Pretreatment Program and/or the operation of the WWTP." As according to the NPDES Permit,
Part IV, Section C, 2, a.: "Under no circumstances shall the Permittee allow introduction of
pollutants or discharges into the waste treatment system or waste collection system which cause
or contribute to Pass Through or Interference as defined in 15A NCAC 2H .0900 and 40 CFR
403."
On the day of this CEI, this facility was found to be in minimal compliance with the
NPDES permit NC0021504. However, I am very concerned about the following items: 1) the

Mayor Criscoe

potential for I&I to cause NPDES violations. (TSS,_. and possibly other), 2) the difficulty of
operating this POTW without valves at the influent splitter box or between the aeration basins
and the clarifier, 3) the amount of grease in the chlorine contact basin and the amount of solids
present in the chlorine contact basin. This is said because at most other POTW's that I have
inspected, the treated wastewater in the chlorine contact basin were clear and colorless, without
an excessive amount of floating grease particles. Please physically remove the floating grease.
particles from the chlorine contact chamber in order to aid the Effluent bulkhead in preventing
grease particles from escaping from the POTW.
I appreciate the time and professional courtesy that was extended by Sam Stewart during
the inspection. If you have any questions or comments, please contact me at [phone].

Department of Environment and Natural Resources
Coleen H. Sullins, Director
Division of Water Quality
May 1, 2008
To: NPDES Permittees
Subject:. Total Residual Chlorine 50 ug/1 Compliance Level
In a previous letter dated August 14, 2001, the Division of Water Quality (DWQ) notified
NPDES permittees that water/wastewater treatment facilities with Total Residual Chlorine
(TRC) effluent limits would be required to use analytical methods that produce detection levels
below their permit limit by July 1, 2002. [Note: TRC permit limits are typically set between 17
to 28 ug/1 for discharge to freshwater systems, and 13 ug/1 for discharge to saltwater systems].
This requirement was based on an Environmental Protection Agency (EPA) audit of the NC
enforcement program. It was also necessary to ensure water quality protection and compliance
with state monitoring regulations [15A NCAC 2B.0505(e)(4)].
Since that time, DWQ has received several inquiries regarding difficulties with the new
analytical methods, primarily focused on 1) lack of precision with field instrumentation at low
TRC levels for both water and wastewater treatment plants; and 2) manganese interference with
TRC measurement at several water treatment plants. Some facilities have overcome these
problems through various changes, such as: 1) switching dechlorination chemicals; 2) adding a
second dechlorination feed; 3) changing analytical methods; 4) incorporating manganese
correction; 5) switching to UV disinfection; 6) removing sludge from water treatment plant
settling basins. Also, the DWQ Laboratory Certification staff have provided extensive field
assistance for the new lab methods. Still, some analytical issues remain. In response to the
permittee's concerns, the Division is providing the following changes to its TRC requirements:
❑ TRC Compliance Level Changed to 50 ug/l. DWQ continued discussions with EPA
regarding analytical difficulties with TRC measurements, and in March 2008 received
EPA approval to allow a 50 ug/1 TRC compliance level. This will not change the
analysis, annual verification of meter performance; or data reporting, but simply how the
reported values will be evaluated by DWQ from a compliance standpoint. .Facilities. will
still be required ':;to. report actual results on -their .monthly DMR subnnttals but for
compliance purposes all TRC values below 50 ug/1 will be treated as zero. For example,
if the facility has a TRC limit of 17 ug/1 and reports a TRC value of 40 ug/1 on the DMR,
this value will be considered compliant under this new policy. This new compliance
level is effective March 1, 2008 (beginning with March 2008 DMR submittals).
DWQ will continue to incorporate TRC effluent limitations into NPDES permits for all
water/wastewater treatment facilities that discharge chlorine -bearing wastestreams to surface
waters. While this new TRC compliance level of 50 ug/1 is effective beginning March 1, 2008, it
will be incorporated into existing NPDES permits with TRC effluent limits upon permit renewal.
At that time, the following TRC footnote language will added to the Effluent Limitations Sheet:
"The facility shall report all effluent TRC values reported by a NC certified laboratory including
field certified. However, effluent values below 50 ug/1 will be treated as zero for compliance
purposes."

Town of Biscoe Wastewater Treatment Facility
NPDES Permit No. NC0021504
Montgomery County
Dear Mr. Lopez:
AN 2;q?O
DENR FAYETTEVILLE REGIONAL OFFICE
Please except this letter of response to the Compliance Evaluation Inspection (CEI) Report received
by the Town's office dated March 21, 2013. This CEI was sent after an inspection that was
performed on February 27, 2013 at the Town of Biscoe Wastewater Treatment Plant. Each of the
seventeen items are addressed below and respectively numbered:
1. The most recent Inflow & Infiltration Study has been completed and was presented to the
Town Board at the April 8th meeting. Proposed repairs will be included in the FY 2013-2014
budget planning.
2. Funding has been found via CWMTF Grand (2012-549) from 2012 fiscal year. Total project
applied for was $800,000 with a 50% local match. Total available to date is $250,000 using a
local match of 50%. Making a total of $500,000.
3. The responses to 3 are as follows:
a. . < 10 ug/L will show on the DMR for residual chlorine. Results greater than 10 the
actual results will be reported.
b. Will fix this problem by reading ug/L only. The mg/L box will be deleted.
c. Data entry will be checked more closely.
4. As stated in #2 we in the process of getting grant money. At this point we plan on installing
valves on the lines going to the aeration basins so we can control the flow of water to these
basins. At this point we will work with a local machine shop to get new scum/solids baffles
made and installed.
5. See "Handout #1"

Mr. Dale Lopez Page 2 April 29, 2013
6. Staff has noticed some problems with China Eight and Autumn Care. Staff will meet with
these businesses and address these problems/issues.
7. Staff is working to update our Industrial Waste Survey (IWS) short -forms. This information
will be submitted on the report due on June 14, 2013.
8. Town Staff will be meeting with the three industries listedduring the first week of May
2013. It is our intent to give these industries one month to complete these forms. This
information will be submitted on the report due on June 14, 2013. The three listed
industries have changed ownership and names; Telfa Corp. is now Central Carolina Hosiery,
the metal fabrication machine shop on Sedberry Road is K&M Machine, and Grede now
owns two sites (Grede purchased the former GTL Corp.).
9. The list of industries that will receive IWS will be sent in the June 14, 2013 response. Staff
has questions regarding who to contact and will be consulting with you within the week.
10. The list of industries will be sent in with the June 14, 2013 response.
11. Copies of all responses will be sent on June 14, 2013.
12. We have been more vigilant in cleaning out the chlorine chamber. If we are able to get the
grant money that was discussed in item #2, we will be able to hold water in the aeration
basins so we can better clean the chlorine contact chamber.
13. Staff physically removes all accumulated floating grease particles daily from the chlorine
contact chamber and the clarifier with a fine pool net.
14. Staff will continue to educate the public on grease problems by word of mouth and
handouts.
15. Bulkheads have been considered and they will be put into place ASAP.
16. Staff was unable to locate said bottle for ph10 buffer. Staff will keep a check on aII buffers
to help solve this problem. Any buffers found to be out of date will be replaced.
17. The 5-standard chlorine curve has been performed. See "Handout #2"

HANDOUT #1
We can help prevent most sewer back-ups and overflows with a progressive preventive main-
tenance program.
Sewer back-ups and overflows are often caused by improper materials such as fats, oils and
grease being flushed into the sewer system. Fats, oils and grease are lighter than water and
tend to accumulate at the top and side of sewer pipes building up until a blockage occurs.
Sanitary sewer systems are designed to handle three things: used water, human body waste,
and toiler paper. Some simple things to prevent blockages and save money are shown below.
Most sewer back-ups occur between the house and the Town's sewer main; making the prop-
erty owner responsible for correcting the problem. Avoiding_: blockages avoids plumbing bills.
