1. PROHIBITED DISCHARGE STANDARDS
The permittee shall comply with the Prohibited Discharge Standards included as Article
II, Section 1 of the City of Greensboro Sewer Use and Pretreatment Ordinance.
2. REPRESENTATIVE SAMPLING
Samples and measurements taken as required in this permit shall be representative of the
volume and nature of the monitored discharge. All samples shall be taken at the
monitoring point(s) specified in the permit. Monitoring points shall not be changed
without notification to, and written approval by, the City of Greensboro Industrial Waste
Section.
3. DEFINITIONS
a. A composite sample for monitoring requirements, is the collection of:
i. A minimum of four grab samples collected, manually or mechanically, at
equally spaced time intervals during the entire discharge period on the
sampling day [Time Composite]; or
ii. A minimum of four grab samples collected, manually or
mechanically, and proportioned according to discharge flow during
the entire discharge period on the sampling day [Flow Proportional
Composite]; or
iii. The Industrial Waste Section may allow the Permittee to collect multiple
grabs during a 24-hour period which are composited prior to analysis as
allowed under 40 CFR 403.12(g)(3) ["Grab Composite Sample" for cyanide,
totals phenols, sulfides, volatile organics, and oil & grease].
b. A daily monitoring frequency shall mean each working day on which a regulated
wastewater discharge occurs.
c. A grab sample for monitoring requirements is a single "dip and take" sample
collected at a representative time and point in the discharge stream.
d. An instantaneous measurement, for monitoring requirements is a single reading,
observation, or measurement.
e. A calendar day is defined as the period from midnight of one day until midnight of
the next day. However, for purposes of this permit, any consecutive 24-hour period
that reasonably represents the calendar day may be used for sampling and flow
measurement. This period shall be designated by the SILT and should not deviate by
more than::L 30 minutes. The site-specific sampling period during this calendar day
will be defined in Section IV of this permit.
f. The monthly average is defined as the arithmetic average of all samples collected
during a calendar month for a particular parameter. One sample can constitute a
monthly average.
City of Greensboro SIUPERMIT Standard Conditions(September 2018 Version) Page 2

g. The daily average is defined as the arithmetic average of all samples collected for a
particular parameter during a calendar day.
h. A slug load is any discharge at a flow rate and/or pollutant concentration
(including oxygen demanding pollutants, BOD, etc)which has a reasonable
potential to cause interference or pass-through or in any other way violates the
POTW's regulations, local limits, or Industrial User Permit conditions.
i. A continuous flow measurement is a measure of discharge flow from the facility
which occurs continually without interruption throughout the operating hours of
the facility. Flow shall be monitored continually except for infrequent times when
there may be no flow or for infrequent maintenance activities on the flow device.
Site-specific flow measurement requirements are outlined in Section IV of this
permit.
j. A bypass is the intentional diversion of wastestreams from any portion of a user's
pretreatment process or pretreatment facility.
4. SAMPLING PROCEDURES AND APPROVED TEST METHODS
All measurements, sampling, tests and analyses of the characteristics or properties of
wastewaters conducted to determine compliance with this permit shall be performed in
accordance with the procedures outlined in 40 CFR Part 136 unless specified otherwise in
the monitoring conditions of this permit.
All user self-monitoring data submitted for compliance determination shall be performed
by a laboratory certified by the State of North Carolina Division of Water Quality to
conduct wastewater analysis for the appropriate parameters, or by an on-site SIU
laboratory approved by the City of Greensboro Industrial Waste Section for the
appropriate parameters. It is the responsibility of the SIU to ensure that the laboratory
used is certified or approved for each parameter reported under this permit.
All test procedures must produce minimum detection and reporting levels that are at or
below the limits contained in this permit. All data generated must be reported down to
the minimum detection or lower reporting level of the procedure. Any matrix
interferences that cause reporting levels higher than permit limits must be documented to
prove that every effort has been made to obtain the minimum detection levels. The
Industrial Waste Section reserves the right to invalidate data and require resampling for
parameters with detection levels higher than permit limits.
City of Greensboro SIU PERMIT Standard Conditions(September 2018 Version) Page 3

5. ADDITIONAL MONITORING
a. If the permittee monitors any pollutant at the sampling location designated in the
permit more frequently than required by the permit, using the approved analytical

limitation or condition. The permittee shall repeat the sampling and analysis for the non-
compliant parameter(s) and submit the results of the repeat analysis to the City of
Greensboro Industrial Waste Section within 30 days after becoming aware of the
violation.
b. Noncompliance with Local Pollutant Allocations
The permittee may conduct additional sampling and analyses for any Local Pollutant
Allocation exceedance and the data will be used for compliance calculation purposes.
The permittee shall conduct additional sampling and analyses as directed by the Industrial
Waste Section on a case-by-case basis.
7. SIGNIFICANT NONCOMPLIANCE [SNC]
The Federal Pretreatment Regulations [40 CFR Part 403.8(f)(2)(viii)] require that the
City of Greensboro publish at least annually in a newspaper of general circulation that
provides meaningful public notice within the jurisdiction served by the POTW, a list of
industrial users which, at any time during the previous twelve (12) months, were in
"significant noncompliance"with applicable pretreatment requirements.
For the purposes of this provision, an SIU is in significant noncompliance [SNC] if its
violation(s)meets one or more of the following criteria. Additionally, any violation by an
Industrial User that meets the criteria in Parts (c), (d) or(h)shall also be SNC.
a. Chronic violations of wastewater discharge limits, defined here as those in
which sixty-six percent(66%) or more of all of the measurements taken for the
same pollutant parameter(not including flow) during a six (6) month period
exceed(by any magnitude) a numeric Pretreatment Standard or Requirement
including instantaneous limits;
