A "Representative Storm Event' is a storm event that measures greater than 0.1 inches of rainfall and that
is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has
occurred. A single stone event may contain up to 10 consecutive hours of no precipitation.

Permit No. NCG030000
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a measureable storm event at each stormwater
discharge outfall (SDO). Only SDOs discharging stormwater associated with industrial activity must
be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office. See Definitions.

Footnotes:
1 Measurement Frequency: Twice per year during a measureable storm event.
2 Grab samples shall be collected within the first 30 minutes of discharge.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the letter granting ROS shall be kept on site.
4 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations,
manufacture semiconductors, manufacture electronic crystals, or manufacture cathode ray tubes. For purposes of this
permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the
facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11. for
semiconductor manufacture use the definition as found in 40 CFR 469.12: for electronic crystal manufacture use the
definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in
40 CFR 469.31.)
5 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
or local rain gauge reading must be recorded. Where isolated sites are unmanned for extended periods of
time, a local rain gauge reading may be substituted for an on -site reading
The permittee shall complete the analytical samplings in accordance with the schedule specified
below in Table 2, unless adverse weather conditions prevent sample collection (see Adverse
Weather in Definitions). A minimum of 60 days must separate Period 1 and Period 2 sample
dates, unless monthly monitoring has been instituted as part of other requirements of this permit.
Inability to sample because of adverse weather conditions must be documented in the SPPP and
recorded on the DMR. The permittee must report the results from each sample taken within the
monitoring period (see Part III, Section E).

to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.1 1; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ the
"TTO monitoring waiver, the discharger shall sign the following certification statement:
"Eased upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO),
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
