A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 37 % at the effluent limit of 0.45 MGD.
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 44 % at the effluent limit of 0.6 MGD.
The permit holder shall perform at a minimum, quarteriu 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 ofJanuary, April, July and October. 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:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.

Permit No. NC0040011
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
Quality 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.

Facility Description: The Yanceyville WWTP has a capacity of 0.45 MGD and consists of mechanical bar
screen, manual grit chamber, influent pump station, sequencing batch reactor, chlorine contact chamber,
dechlorination, and aerated sludge lagoon. The permit includes limits for two flow scenarios, 0.45 MGD and
0.6 MGD. The permit includes limits for BOD, TSS, ammonia, fecal coliform, DO, pH, TRC, Cadmium, Lead,
Cyanide, Mercury, and Chronic Toxicity, and monitoring for temperature, conductivity, TN, TP, Cadmium,
Chromium, Copper, and Silver. The town has not upgraded to 0.6 MGD. They are not planning to do the
upgrade in the near future as average flow is well below the permitted flow.
Basin Plan: In the 2006 basin plan, this segment of Country Line Creek (AU# 22-56-(3.7) is rated as
Supporting for aquatic life, and the bioclassification is Good (assessment done in 2004). The stream is not
rated for recreation. The watershed is experiencing some development, and erosion and habitat deficiencies
were noted; therefore, the basin plan recommends implementation of BMPs for sediment control and
improvement of riparian areas along the creek.
Pre -Treatment: The town has no Significant Industrial Users.
DMR Review: DMRs for the period of January 2004 to May 2007 were reviewed. The average flow was
0.281 MGD, Average BOD was 10.03 mg/I, TSS averaged 10.36 mg/I, Ammonia averaged 1.09 mg/I, Residual
Chlorine averaged 9.5 i,tg/I (most were <10 mg/I).
See attached report for a list of violations.
Priority Pollutant Scan: The requirement to do the priority pollutant analysis does not apply to this facility.

NPDES Permit Number NC0040011, Caswell County
Dear Mrs. Mrs. Bryant:
In response to your request for NPDES Permit Renewal concerning the Town Of Yanceyville
(NC# 0040011), Research & Analytical Laboratories, Inc. (RAL) has prepared the enclosed required
renewal package information for your review. Please note the following:
1) The Town of Yanceyville is requesting a renewal of NPDES Permit Number NC0040011
which will expire 31 May 2007. RAL anticipates no changes at the facility since issuance
of the last permit.
2) Enclosed are one (1) original and two (2) copies of the completed application form for
NPDES Permit renewal.
3) A Sludge Management Plan at the Town of Yanceyville consists of a documented
sludge hauling subcontractor who periodically removes digested sludge from
Yanceyville's sludge holding lagoon delivers waste sludge to an approved sludge land
application site.
4) Because of the lack of Significant Industrial Users or industries that fall under Federal
Categorical Standards the Town of Yanceyville has not been required to have a
Pretreatment Program for over eight years. Mr. Charles Weaver instructed us to include
this statement as the reason that Yanceyville is not required to complete Part D (expanded
effluent testing).
If you should have any questions concerning this renewal request please feel free to contact Mr.
Dennis Hodge with Research & Analytical Laboratories, Inc. at [phone].
Sincerely,
James M. Cheshire

Gil- here's the compliance feedback from WSRO on the facilities that we highlighted with
potential compliance problems in the Roanoke Basin. Of the 20 listed facilities, WSRO
indicates that 2 have connected, and 2 should have a Special Condition placed in the
draft permit renewal requesting a Wastewater Management Plan to address compliance
problems (see below):
* NC0021075 Town of Madison- no longrer discharging, connected to
Mayodan
* NC0028011 Town of Stonevills- no longer discharging, connected to
Mayodan
* NC0059251 Quail Acres MHP- Require Wastewater Management Plan
* NC0040011 Yanceyville WWTP- Require Wastewater Management Plan
Mike T prepared a generic Wastewater Management Plan Special Condition that can be
tailored to the problems at the specific facility, and permit writers should discuss with
him. If you think some other facilities on the list might need a Special Condition,
please discuss with Tedder. I'll put copies of the WSRO comments in the NPDES files, to
alert the assigned permit writers of the additional requirements. For the remaining
Roanoke Basin, I've already received feedback from WARO, and I'm still awaiting RRO
feedback (due to us by Oct. 6).

The Roanoke Basin (subbasins 030201-030210) is next in line for NPDES wastewater
permit renewals, with 77 permit renewals falling within three regions: WSRO (n=47),
RRO (n=18), and WARO (n=12). The Roanoke permits begin to expire 1/31/2007, which
means that NPDES staff will start sending drafts to public notice in December06.
NPDES staff attempts to incorporate compliance into permit renewals by reviewing the
compliance record to identify problem facilities, and discussing with the applicable
Regions whether the permit renewal should contain any special conditions to address
continuing compliance problems.
Similar to the Cape Fear renewals, I reviewed a BIMS download of enforcement cases
during 2001-05, and used a subjective compliance threshold of 3+ enforcement cases
over the last 2 years, or 5+ enforcement cases over the past 5 years, to identify
potential problem facilities. This threshold resulted in 30 facilities, spread between
WSRO (n=20), RRO (n=7), and WARO (n=3). These facilities are listed by Region in the
attached spreadsheet. The next step is for NPDES/Region to review the facility lists
and determine what permitting conditions, if any, would be appropriate for each listed
facility. For some facilities, the cases may be older and the problem may already be
resolved, or is currently being addressed through SOC, etc, in which case no
permitting action is necessary. The most common permiting action for a problem
facility has been to add a Special Condition requiring preparation of a Wastewater
Management Plan that focusus on specific problems and how the facility plans to
resolve them.
I'll leave it to the Regions to determine how they want to proceed. Regions can
either review their listings and enter comments on the spreadsheet and send back, or
NPDES can call/visit the Region to discuss each listed facility. Both ways have
worked in the past. Either way, I'd like to complete this task BY SEPTEMBER 30,
before NPDES staff begins the permit renewals. Any permitting conditions deemed
appropriate by Region/NPDES will then be placed in the permit renewal files, and
ultimately incorporated into the draft permit. If Regions have any questions, feel
free to contact me or the following NPDES Regional Office Contacts: WSRO- Charles
Weaver; RRO- Vanessa Manuel; WARO- Karen Rust.

YES_ This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YES_ This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
/ limits). Basin Coordinator to make case -by -case decision.
YES t/ This permit CANNOT BE EXPEDITED for one of the following reasons:
p g
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
Limits based on reasonable potential analysis (metals, GW remediation organics)
