Permit No. NCS000570
PART C: QUALITATIVE MONITORING OF STORMWATER DISCHARGES
The purpose of qualitative monitoring is to implement a quick and inexpensive way to
evaluate the effectiveness of the permittee's SWPPP, to identify the potential for new
sources of stormwater pollution, and to prompt the permittee's response to pollution.
C-1. Visual Inspections
(a) Visual inspections shall be made at each stormwater discharge outfall (SDO) that
discharges stormwater associated with industrial activity unless representative
outfall status specifically for visual monitoring has been approved in writing by the
Division.
(b) Visual inspections shall be performed concurrent with required analytical
monitoring.
(c) Visual inspections are not required to be performed outside of the facility's normal
operating hours.
(d) Visual inspections shall be recorded on the Division's Stormwater Discharge Outfall
Qualitative Monitoring Report (QMR) form and shall include observations of:
• Color;
• Odor;
• Clarity;
• Floating Solids;
• Suspended Solids;
• Foam;
• Oil Sheen;
• Deposition at or immediately below the outfall;
• Erosion at or immediately below the outfall; and
• Other obvious indicators of stormwater pollution.
(e) Inability to perform inspections because of adverse weather or lack of discharge
during the monitoring period shall not constitute a failure to monitor if the event is
documented in the SWPPP and recorded on the Qualitative Monitoring Report.
C-2. Qualitative Monitoring Response
(a) If the permittee's qualitative monitoring indicates that the SWPPP and/or existing
stormwater BMPs are ineffective, or that significant stormwater contamination is
present, then the permittee shall investigate potential causes, evaluate the feasibility
of corrective actions, and implement those feasible corrective actions within sixty
(60) days.
(b) A written record of the permittee's investigation, evaluation, and response actions
shall be kept in the SWPPP.

• Period 2: July 1- December 31.
D-2. Baseline Sampling Benchmarks
(a) Analytical results for each parameter shall be compared to the benchmark values for
the appropriate receiving stream classification as provided in Table 1. An
exceedance of a benchmark value is not a permit violation; however, failure to
respond in accordance with part D-2 paragraph (b) of this permit is a permit
violation.
(b) An exceedance of any benchmark value in Table 1 shall require a tiered response for
that parameter. A single exceedance of a benchmark value shall require a Tier One
response for that parameter. Two benchmark value exceedances in a row shall
require a Tier Two response for that parameter. Four benchmark exceedances for a
parameter within a five (5) year period shall require a Tier Three response for that
parameter.

D-3. Methodology for Collecting Samples
(a) Grab samples shall be collected within the first 30 minutes of discharge. If physical
separation between outfalls prevents collecting all samples within the first 30
minutes, the permittee shall begin sampling within the first 30 minutes and shall
continue until completed.
(b) Samples collected shall be characteristic of the volume and nature of the permitted
discharge.
(c) Samples shall be collected during a measurable storm event. The previous
measurable storm event must have been at least 72 hours prior.
(d) Lack of a discharge from an outfall for the monitoring period, or inability to collect a
sample because of adverse weather conditions during a monitoring period, shall not
constitute failure to monitor as long as those conditions are reported on the
monitoring period DMR and noted in the SWPPP as "No Flow" or "No Discharge".
(e) Sampling is not required to be performed outside of the facility's normal operating
hours.
Page 12 of 36

Permit No. NCS000570
(f) If the sampled storm event coincides with a known non-stormwater discharge that is
deemed permitted under 15A NCAC 02H .0106, then this shall be noted on the
stormwater discharge monitoring report.
D-4. Locations for Collecting Samples
Samples shall be collected at all stormwater discharge outfalls (SDOs) that discharge
stormwater associated with industrial activity. If the Division has issued a representative
outfall status (ROS) approval letter, then the permittee shall collect samples from all SDOs
in accordance with the ROS approval letter.
(a) All samples shall be taken before the discharge joins or is diluted by any other waste
stream, body of water, or substance.
(b) Monitoring points as specified in this permit shall not be changed without written
notification to and approval by the Division [40 CFR 122.41(j)].
(c) Analytical monitoring is not required for the outlet of any basin or pond designed to
contain the 25-,year. 24-hour storm without discharging, and that can regain capacity
to hold such an event within five (5) days' time through means other than discharge
to surface waters.
D-5. Tier One Response: Single Benchmark Exceedance
(a) If any sampling result is above the benchmark value for any parameter at any outfall,
then the permittee shall respond in accordance with Table 2 to identify and address
the source of that exceedance for the parameter(s).
(b) Each required response shall be documented in the SWPPP as each action occurs
