1. Submitdischarge momtoruig,reports electronically using the NC DWR's eDMR application system[See section A.(2.)].
2. OM shall be monitored with each,discharge event. During periods of no flow, the Permittee shall submit a
signed;monthly Discharge Monitoring RepoIt5(DMR) indicating"No discharge."Flow may be monitored using any
one of four methods:
,i'a),,Measure flow cont4ieusly
`b) Calculate flow (see'Rational Equation below) based on total rainfall per unit area
\, draining to the outfall; exclude built-upon areas (best method for facilities with large
i inoff-collection ponds)
The°Rational Equation: Q=KuCIA,where:
Q = flow'(peak flow rate(cfs or m3/sec)
Kuunits conversation factor = 1.008 for U.S. standard units (usuallyignored
= ��
because it is so close to 1),or 0.278 for SI units
C = dimensionless runoff coefficient for the watershed, loosely defined as the
ratio of runoff to rainfall
I = intensity of rainfall taken from the intensity-duration-frequency curves for the
specified design return period at the time of concentration, tc (in/h or
mm/h).tc=time of concentration(time after the beginning of rainfall excess
when all portions of the drainage basin are contributing simultaneously to
flow at the outlet).
A = area of tributary watershed(acres or km2)
Page 3 of 8

Permit NC0049905
The rational equation is used to calculate the runoff from a region,given:
i) the runoff coefficient which accounts for infiltration and other potential
losses in the region
ii) the rainfall intensity to the region
iii) the time it takes for runoff to travel from the region's upper reaches to its
outlet
iv) the region's drainage area
c)Estimate flow at 20-minute intervals duringthe entire discharg9
d)Report flow based on discharge pump logevent� .
3. Effluent monitoring and limitation only apply if chlorine or a chlorine derivative is added,to the waste stream during treatment.
The Division shall consider all effluent TRC values reported below 50 gg/L to,be in compliance"with the permit.However,the
Permittee shall continue to record and submit all values reported b a North Carolina certified'.iaboratory (including field
certified),even if these values fall below 50µglt.
4. Oil and grease samples shall be skimmed from the surface of6a quiescent(calm water)zone.
5. The discharge from this facilityshall not cause turbidity;in the receiving stream to exceed 50 NTiJ., If the instream
turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause turbidity to>increase in the
receiving stream. Therefore, if the effluent measurement exceeds 50 NTIJ,. the Permittee shall sample upstream and
downstream turbidity in the receiving waterbody, within 24 hours; to'demonstrate the existing turbidity level in the
receiving waterbody was not increased.All data shall be reported d'n he DMRs. (See 15A NCAC 2B .0211 (21)).
6. The temperature of the effluent shall be regulated so-as not to cause an'mcrease in the temperature of the receiving stream
of more than 2.8°C and in no case cause the ambient water temperature to,exceed 32°C.
The permittee shall obtain authorization from the Division prior to the use of any chemical additive in
the discharge. The permitte-shall,.notify the,Director it'writing-.at least ninety (90) days prior to
instituting use of any additional-additive in the discharge which may be toxic to aquatic life (other than
additives previously appioyed by the;Division). Such notification shall include completion of Biocide
Worksheet 101 (if applicable), a copyFofthe MSDS for the additive, and a map indicating the discharge
point and receiving steam:,
There shall-be-no-chromium, zinc, or copper added to the discharge except as pre-approved
additives`to biocidal Compound's.'
,
All samples collected should be from"a representative discharge event.
Therehs all be no discharge of floating'solids or visible foam in other than trace amounts.

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or
alternative forms approved'by the Director. Duplicate signed copies shall be submitted to the mailing
address above. See"How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
