Reference: Storm Water Pollution Prevention Plan — Monitoring Report
NCG030000 -- COC NCG030253
This report contains the Monitoring Reports for the storm water runoff on 3/1/2019.
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
2019 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 2019
I was able to observe a water discharge flow from the property before the event ended
and the water flow quickly diminished shortly afterward. 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.

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 pennittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the pennittee obtains approval from the local DEMLR
Office.
