hour during the entire discharge period on the sampling day Sampling day
shall be a typical production, and discharge day.
2. Daily Monitoring Frequency
Daily monitonng frequency as specified in this IUP shall mean each day of
discharge.
3. Continuous/Daily Monitoring Frequency
For flow, "continuous" refers to the requirement to use a continuous
recording discharge flow meter. See Part III, 3 for more details For flow,
"daily" shall mean the permittee shall read the flow meter totalizer every
day, including weekends and holidays, convert this to a daily flow, and
report these daily flows to the Authority with the report due under Part II,
2.
4. "Every Sample" Monitoring Frequency
A monitoring frequency of"every sample" as specified in this IUP shall
mean each time a composite or grab sample is collected
5. Grab Sample
Grab sample for the monitoring requirements of this IUP, is defined as a
single "dip and take" sample collected at a representative point in the
discharge stream.
6. Instantaneous measurement
An instantaneous measurement for the monitoring requirements of this IUP
is defined as a single reading, observation, or measurement.

the effluent joins or is diluted by any other wastestream, body of water, or
substance. Monitoring points shall not be changed without notification to, and
approval by, the Authority
2. Reporting
a) Monitoring results obtained by the permittee shall be reported on forms
specified by the Yadkin Valley Sewer Authority, postmarked no later than the
twentieth day of the month following the month in which the samples were

volume of its wastewater at least 180 days before the change The permittee shall
not begin the changes until receiving written approval from the Authority. Also
see Part II, 30 below for additional reporting requirements for spill/slug issues
Significant changes may include but are not limited to:
(a) increases or decreases to production;
(b) increases in discharge of previously reported pollutants;
(c) discharge of pollutants not previously reported to the Authority,
(d) new or changed product lines,
(e) new or changed manufacturing processes and/or chemicals
The Authonty will respond within 10 days of such notice stating if it deems the
proposed "changed conditions"to be significant or not.
26. Construction
No construction of pretreatment facilities or additions thereto shall be begun until
Final Plans and Specifications have been submitted to the Authority and written
approval and an Authorization to Construct (A to C)have been issued
27. Reopener
The permit shall be modified or, alternatively,revoked and reissued to comply with
any applicable effluent standard or limitation for the control of any pollutant shown
to contribute to toxicity of the WWTP effluent or any pollutant that is otherwise
limited by the POTW discharge permit The permit as modified or reissued under
this paragraph may also contain any other requirements of State or Federal
pretreatment regulations then applicable
28. Categorical Reopener
This permit shall be modified, or alternatively, revoked and reissued, to comply
with any applicable effluent standard or limitation issued or approved under
Sections 302(b)(2)(C) and (D), 304(b)(2), and 307(a)(2) of the Clean Water Act, if
the effluent standard or limitation so issued or approved-

pproved•1 ) contains different conditions or is otherwise more stringent than any
effluent limitation in this permit, or
2.) controls any pollutant not limited in this permit
The permit as modified or reissued under this paragraph shall also contain any other
requirements of the Act then applicable.
29. General Prohibitive Standards
The permittee shall comply with the general prohibitive discharge standards in 40
CFR 403.5 (a) and (b) of the Federal pretreatment regulations

PART II
General Conditions
30. Potential Problems
The permittee shall provide protection from accidental and slug discharges of
prohibited matenals and other substances regulated by this permit. The permittee
shall notify the Authority immediately of any changes at its facility affecting the
potential for spills and other accidental discharge, discharge of a non-routine,
episodic nature, a non-customary batch discharge, or a slug load as defined in the
Sewer Use Ordinance.
Additionally, the permittee shall notify the Authority immediately of all discharges
that could cause problems to the POTW including any slug loadings as defined in
the Sewer Use Ordinance. If the permittee experiences such a discharge, they shall
inform the Authonty immediately upon the first awareness of the commencement
of the discharge. Notification shall include location of the discharge,type of waste,
concentration and volume if known and corrective actions taken by the permittee
A wntten follow-up report thereof shall be filed by the permittee within five (5)
days, unless waived by the Authority.

PART III
Special Conditions
1. Slug/Spill Control Plan
In addition to the requirements in Part II, the permittee shall implement, operate,
and/or maintain the specific protection measures, activities, plans, etc as outlined
within the approved permittee slug/spill control plan and enclosed herein.
Description of Measure, Activity, Plan, Etc. Implementation Date
Revised Slug/Spill Plan Submitted on 2/2/18 Approved 3/6/18
Implement Slug/Spill Plan Continuous for duration of permit
Permittee shall submit new slug/spill plan if changes occur that were not previously
outlined in the approved plan
If a measure fails, the permittee shall notify the Authority within 24 hours
2. Sludge Management Plan
Ninety days prior to the initial disposal of sludge generated by any pretreatment
facility, the permittee shall submit a sludge management plan to the Authority
3. Flow Measurement Requirements
(For SIUs with discharge flow meters)
The permittee shall maintain appropriate discharge flow measurement devices and
methods consistent with approved scientific practices to ensure the accuracy and
reliability of measurements of the volume of monitored discharges Devices
installed shall be a continuous recording flow meter capable of measunng flows
with a maximum deviation of±0.5%from true discharge rates throughout the range
of expected discharge volumes At the time of issuance of the permit, this method
consists of ultrasound discharge flow meter at sample point for Pipe 001 The
totalizer shall be non-resettleable. The devices shall be installed, calibrated, and
maintained to ensure accuracy. The meter shall be calibrated every year and
documentation submitted to the Authority within 15 days. Modifications to the
flow metering equipment shall be approved by the Authority prior to installation
If a required flow measurement device fails, the Authority shall be notified within
24 hours
4. Certified Laboratory Analysis
Pollutant analysis shall be performed by a North Carolina Division of Water
Quality Certified Laboratory that is certified in the analysis of the pollutant in
wastewater.

D Rationale For Limitations. (As listed on PART I, Section F of the IUP)
RATIONALE#1 (General Explanation):
Discharge restrictions are set based on expected flow from plant production
phases, WWTP pH and gnt limitation, YVSA SUO, and evaluation of the
STMP.

IUP Synopsis
RATIONALE#2 (Rationale Specifics for Limitations).
The following rationale was used for developing IUP Limits.
Parameter Rationale
Flow Per IU request (peak instantaneous flow is based on limit
of receiving Candlewycke Pump Station capacity).
pH Per WWTP NPDES Permit. IU's flow is significant and
would require additional buffering at WWTP if outside 6
to 9 SU's
Gnt ! Based on WWTP gnt removal system capacity, IU
monthly average discharge of 0.12 mgd,particle size>
0 2 mm, and specific gravity(S.G) of glass 2 65
Limitation also needed to protect downstream equipment,
and is therefore limited to normal domestic sewage
characteristic
Oil and Grease Per YVSA SUO (Section 2 3 Local Limits)
RATIONALE#3 (Categorical Industrial Limits, with no Over Allocation Situation).
