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 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 DEMLR
Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Notes:
1. Samples shall be collected at each stormwater discharge outfall unless representative outfall status
has been granted and documented by the Division of Water Quality. A copy of the letter granting
representative outfall status shall be kept on site.
2- TSS benchmark for ORW, HWQ, Trout or PNA waters is 50 mg/L.
3. Only required for sites where vehicle maintenance activities occur.
4. All samples must be grab samples. Grab samples shall be collected within the first 30 minutes of
discharge from a stormwater discharge outfall (SDO).
5. All samples must be collected during a measurable storm event. A measurable storm event is an
event that results in an actual discharge from the permitted site outfalls. The previous measurable
storm event must have been at least 72 hours prior. If no discharge occurs during a sampling period,
a monitoring report indicating "No Flow" must be submitted within 30-days of the sampling period.
6. For each sampled measurable storm event the total precipitation must be recorded using an on -site
rain gauge.
7. The permittee shall complete the analytical samplings in accordance with the schedule specified
above, unless adverse weather conditions prevent sample collection. Inability to sample due to
adverse weather conditions must be documented in the SPPP and reported on the appropriate DMR
form (Appendix A).
8. A minimum of 60 days must separate each monitoring event unless monthly monitoring has been
instituted under a Tier Two response
9. The permittee shall compare monitoring results to the above -referenced benchmark values for each
discharge characteristic. Exceedances of benchmark values require the permittee to increase
monitoring, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program, as specified by the general permit.
10. Failure to monitor semi-annually per permit terms immediately institutes monthly monitoring for all
stormwater parameters. After six months of monthly monitoring, the permttee may make a request in
writing to the Division of Water Quality to return to a semi-annual monitoring schedule.

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 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 DEMLR
Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Notes:
1. Samples shall be collected at each stormwater discharge outfall unless representative outfall status
has been granted and documented by the Division of Water Quality. A copy of the letter granting
representative outfall status shall be kept on site.
2. TSS benchmark for ORW, HWQ, Trout or PNA waters is 50 mg/L.
3. Only required for sites where vehicle maintenance activities occur.
4. All samples must be grab samples. Grab samples shall be collected within the first 30 minutes of
discharge from a stormwater discharge outfall (SDO).
5. All samples must be collected during a measurable storm event. A measurable storm event is an
event that results in an actual discharge from the permitted site outfalls. The previous measurable
storm event must have been at least 72 hours prior. If no discharge occurs during a sampling period,
a monitoring report indicating "No Flow" must be submitted within 30-days of the sampling period.
6. For each sampled measurable storm event the total precipitation must be recorded using an on -site
rain gauge.
7. The permittee shall complete the analytical samplings in accordance with the schedule specified
above, unless adverse weather conditions prevent sample collection. Inability to sample due to
adverse weather conditions must be documented in the SPPP and reported on the appropriate DMR
form (Appendix A).
8. A minimum of 60 days must separate each monitoring event unless monthly monitoring has been
instituted under a Tier Two response
9. The permittee shall compare monitoring results to the above -referenced benchmark values for each
discharge characteristic. Exceedances of benchmark values require the permittee to increase
monitoring, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program, as specified by the general permit.
16. Failure to monitor semi-annually per permit terms immediately institutes monthly monitoring for all
stormwater parameters. After six months of monthly monitoring, the permitee may make a request in
writing to the Division of Water Quality to return to a semi-annual monitoring schedule.

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'measuirable 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 certify that this report is accurate and complete to the best of my knowledge:

(See information below,)
�es ❑ No
Please verify whether Qualitative Mnnitorinq must be performed diu•ing o "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 "nneasureable "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 clays) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive fours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous illeasurable. 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.

Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit?
(See information below.)
�es ❑ 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 certify that this report is accurate and complete to the best of my knowledge:

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vag, 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, l
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
1 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
i interval is representative for local storm events during the sampling period, and the permittee
,_obtains approval From the local DWQ Regional Office.
