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 permiee 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

PLEASE READ Instructions for completing this farm on the reverse side. Sampler must place a "C" for composite sample or a "G" for N Q 341860
FORM #5 Grab sample in the blocks above for each parameter requested.

SAMPLING INSTRUCTIONS AND FORM COMPLETION
I"AILURE TO PROPERLY CHILL, CHEMICALLY PRESERVE, COLLECT IN PROPER BOTTLE
TYPES, MEET REQUIRED HOLDING TIMES, NEUTRALIZE CHLORINE IN CHLORINE
SENSITIVE SAMPLES, AND SEAL COOLERS WITH TAPE WILL RESULT IN SAMPLES BEING
REJECTED BY THIS LABORATORY AS PER NORTH CAROLINA REGULATORY CODE.
1) Samples not falling within the required guidelines will need to be re -collected. The client will be contacted and informed of any
deviation and asked to collect another set of samples. The client may request the laboratory to proceed with the analyses of the current
samples. Any samples analyzed outside of the required, guldtplines will be "qualified". This means that a note will be included on the
sample result and "Chain of Custody" specifying the.deviatinn. The laboratory is also required to send a letter to the State noting the
deviations. •.
r
n iJ
2) Sample Temperature. Samples for compliance monitoring must be chilled with wet ice to a temperature of 6C or'less. Freezing is
not permitted. Samples delivered to the lab shortly after coliection may not have had enough time to be chilled below W. In this case the
temperature at time of collection must be noted in the space provided. The samples will meet the requirements of the regulation if there
is a temperature drop from the time of collection until received in the lab. Regardless, all samples should be packed iWwet ice using as
much ice as will fit in the cooler.
3) Sample Chemical Preservation. Many samples require a chemical preservation such as Sulfuric Acid or Sodiuni Hydroxide, The
laboratory will either provide the preservative in the sample -bottle, or in the case of 40 mi. Volatiles Vials, provide a bottle of Acid with
detailed descriptions on how to collect the sample. Never rinse sample bottles before collecting samples. Any residue or liquid in the
bottle is required for proper chemical preservation. The lab must verify proper chemical preservation upon arrival in the lab and will note
this information in the spaces provided on the front of this form.
4) Chlorine Neutralization. Some samples require that any Total Chlorine Residual be removed at the time of collection. The lab will
provide the proper neutralizing agent in the sample bottle when technically possible. There are some samples (Total Kjeldahl Nitrogen
and Ammonia Nitrogen) where this is not possible due to interferences between the required chemical preservation (Acid) and the
dechlorinating agent. Therefore, these samples must be de -chlorinated at the time of collection before being placed in our sample bottles.
Sodium Thiosulfate is the chemical of choice to neutralize chlorine. It must be added to your sample and then the spple checked for
Total Chlorine before the sample is poured in our bottle. Facilities using chlorine for disinfection should have a means;of measuring Total
Chlorine. Non -chlorinated sample sources will not need to be checked. The person neutralizing the chlorine must pu1[his initials in the
"Chlorine Neutralized at Collection" row on the front of this form above the proper parameter. Samples such as Coliif rms (which have
Thiosulfate in the bottles shipped from the lab) will be checked for proper neutralization upon arrival in the lab. It is also required that you
note the "Total Chlorine at Collection' on the front of this form for any sample locations applicable. This value would be before any
neutralization is performed.
5) A "C" for Composite Sample or a "G" for Grab Sample should be placed in the box for all requested parameters. Grab temperatures
as well as Composite start dates and times can be recorded in the "comments" section.
6) Other information required to be completed by the client are:
Collection Date and Collection Time for each sample location Temperature at Time of Collection
Printed name of person or persons collecting samples Signature, Date, and Time samples are relinquished
Other added sample locations and analyses required Type Oi' Disinfection
Deletion on the form foi- any samples which are not needed (example: dry upstream location)
Any other information left to be pertinent should be included in the "Comments" section
CONSIDERATIONS:
Coliform and Enterococci samples have a holding time of 6 hours from time of collection to time of analysis. Therefore, samples should
be collected as late in the day as possible to allow enough time for transportation, checking in at the lab and analysis.
BOD, Nitrate, Ortho Phosphorus, Settleable Matter, Turbidity, Color, and MBAS samples have a 48 hour holding time. The lab reserves the
right to establish required sample collection and delivery dates in order to meet the required holding times.
CAUTION
Sample bottles may contain acids or other corrosive and potentially harmful chemicals. Laboratories are required to add these chemicals
for certain analyses in order to comply with EPA preservation requirements. Use extreme care when opening and handling the shipping
container and bottles. If any chemical should get into your eyes, on your skin or on your clothes, flush liberally with water and seek medical
attention. Material Safety Data Sheets (MSDS) are available upon request which specify proper handling and personal protection.

(See info mation below.)
Yes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "nleasureable storm event" (requirements vary, depending on the permit}.
Qualitative monitoring requirements vary. Most. permits require qualitative monitoring to be T
performed during a "representative storm event" or during a "measureable "storib event.-" However,
some permits do not have this requirement. Please refer to these definitions, ifapplicable.
A "representative storm event" is a storm event that measures greater tIlan 0.1 inches of rainfall
and rliat 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 rzo
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site ou fall. The previous iileasurable storm event must have been at least 72 hOlrl'S
prior. The 72-hour storm interval does not apply if the perniittee 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.

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 he
performed during a "representative storm event" or during a "measureable storm event." However,
sorne 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.

....................
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.
