Permit No.: N/C/ G / 0 / 3 / 0 / 0 / 0 / 0 / or Certificate of Coverage No.:
Facility Name: AKG North American Operations, Inc.
County: Orange Phone No. [phone]
Inspector: Diego A. Faria
Date of Inspection: 12/14/2020
Time of Inspection: 8:30 AM
Total Event Precipitation (inches): 1.12
Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit?
(See information below.)
® Yes ❑ No
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 signature, I certifyjh� his report is accurate and complete to the best of my knowledge:

Stormwater Discharge Outfall (SDO)
Qualitative Monitoring Report
For guidance on filling out this form, please visit: http:/Iportal.ncdenr.org/web/Ir/npdes-stormwater/­
Permit No.: N/C/ G / 0 / 3 / 0 / 0 / 0 / 0 / or Certificate of Coverage No.:
Facility Name: AKG North American Operations, Inc.
County: Orange Phone No. [phone]
Inspector: Diego A. Faria
Date of Inspection: 11/30/2020
Time of Inspection: 11:15 AM
Total Event Precipitation (inches): _1.17
Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit?
(See information below.)
® Yes ❑ No
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.
