Reference: Storm Water Pollution Prevention Plan — Monitoring Report
NCG030000 -- COC NCG030253
This report contains the Monitoring Reports for an observation of storm water runoff on
May 4, 2021. The rain event at the time of the outfall inspection was not enough to
qualify as a representative event. I was unable to collect rainwater samples for the
January to June 2021 time period. The weather for the majority of the period was hot
and dry, with intermittent thunderstorms occasionally and for some reason only
happened over the weekends. I was unable to collect the proper samples according to
the permit procedures for the time period: January to June 2021
The Non -storm water Discharge Assessment form has been completed and submitted
with the report. The attached copies of the Qualitative Monitoring Report of SDO report
for your records. The report fulfills the period sampling provisions of the General Permit
No. NCG030000, Certificate of Coverage NCG030253.
If you have questions, or need further information, please contact, David Henderson, of

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
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 storm event may contain up to 10 consecutive hours of no
precipitation.
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.
By this nature, I certify that this report is accurate and complete to the best of my knowledge:

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

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:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I 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 runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
