Division personnel have reviewed and approved your request for modification of the above referenced
permit. Accordingly, we are forwarding herewith the attached draft NPDES discharge permit. This permit
modification includes a change to the effluent mercury limitation for the discharge to the Roanoke River and
elimination of any reference to required method 1631 sampling. Based on upstream mercury date collected
by the facility during the previous year, the effluent mercury limitation has been recalculated assuming a
background mercury concentration of approximately 2.6 ng/L. This background concentration in
conjunction with a 7Q10 flow of 1172 cfs yields an effluent limitation of 0.868 pg/L.

Permit NC0024201
Attention:
A. (4) Chronic Toxicity Permit Limit (Quarterly)
(Discharges to Chockoyotte Creek)
The permit holder shall perform at a minimum, quarterly 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 January, April, July and October. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes.
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.
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.
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.
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 tire 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 Branch at
the address cited above.
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the reporting period for which the report is made.
NOTE: Failure to achieve Lest 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.
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 39%.

(1172+12.902)-12-(1172)-2.575
12.902
The 7Q10 flow of the Roanoke River is approximately 1172 cfs. The permitted flow from the
facility is 8.34 MOD or 12.902 cfs. The upstream mercury concentrations in the above table
were averaged to yield a background concentration of 2.575 ng/L. The allowable concentration
is thus:
Ca
The permit (NC0024201) will be reopened and modified to include a revised mercury limit for
the discharge to the Roanoke River.
During the previous permit renewal, a reasonable potential analysis (RPA) was conducted for
total mercuiy. In addition, the US EPA required the North Carolina Division of Water Quality to
require the facility to meet a 12 ng/L total mercuiy limit end-of-pipe because the receiving
stream is listed for a fish consumption advisoiy. While it is widely recognized that the vast
majority of the mercuiy problem stems from atmospheric deposition, EPA was unyielding on
the matter. EPA did agree to a course of action to help solve this facility's mercuiy problem. If
the facility conducted upstream method 1631 sampling and if those samples were below the
state water quality standard of 12 ng/L, they could request a modification to the permit
allowing for a dilution calculation assuming a background concentration. The table below
summarized the mercuiy date collected by the facility. The allowable concentration
calculations follow.

Division personnel have reviewed and approved your request for modification of the above referenced
permit. Accordingly, we are forwarding herewith the attached modified NPDES discharge permit. This permit
modification includes a change to the effluent mercury limitation for the discharge to the Roanoke River and
elimination of any reference to required method 1631 sampling. Based on upstream mercury date collected
by the facility during the previous year, the effluent mercury limitation has been recalculated assuming a
background mercury concentration of approximately 2.6 ng/L. This background concentration in
conjunction with a 7Q10 flow of 1172 cfs yields an effluent limitation of 0.868 pg/L.

Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the

Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for aD seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Grab Sample
Individual samples of at least 100 ml coUected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
In accordance with (4) above, influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour penod that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.

PART IV
SPECIAL CONDITIONS FOR MUNCIPAL FACILITIES
With regard to the effluent requirements listed in Part I of this permit, it may be necessary for the
Permittee to supplement the requirements of the Federal Pretreatment Standards (40 CFR, Part 403) to
ensure compliance by the Permittee with all applicable effluent limitations. Such actions by the Permittee
may be necessary regarding some or all of the industries discharging to the municipal system.
Under no circumstances shall the Permittee allow introduction of the following wastes in the waste
treatment system:
Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to,
wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees
Centigrade using the test methods specified in 40 CFR 261.21;
Pollutants which will cause corrosive structural damage to the POTW, but in no case Discharges
with pH lower than 5.0, unless the works is specifically designed to accommodate such Discharges;
Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POT\X
resulting in Interference;
Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow
rate and/or pollutant concentration which will cause Interference with the POTW;
Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in
no case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C
(104°F) unless the Division, upon request of the POTW, approves alternate temperature limits;
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will
cause interference or pass through;
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a
quantity that may cause acute worker health and safety problems;
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
The Permittee shall require any industrial discharges sending influent to the permitted system to meet
Federal Pretreatment Standards promulgated in response to Section 307(b) of the Act. Prior to accepting
wastewater from any significant industrial user, the Permittee shall either develop and submit to the
Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from
industries using the municipal system may be present in the Permittee's discharge. At such time as
sufficient information becomes available to establish limitations for such pollutants, this permit may be
revised to specify effluent Emitations for any or all of such other pollutants in accordance with best
practicable technology or water quality standards.
All POTWs must provide adequate notice to the Director of the following:
Any new introduction of pollutants into the POTW from an indirect discharger which would be subject to
section 301 or 306 of CWA if it were direcdy discharging those pollutants; and
Any substantial change in the volume or character of pollutants being introduced by an
as influent to that POTW at the time of issuance of the permit.
For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of
effluent introduced into the POTW', and (2) any anticipated impact of the change on the quantity or quality
of effluent to be discharged from the POTW.
