Permit.
'if pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
ZSee General Permit Table 1, identifying the especially sensitive receiving waters classifications where the more protective benchmark applies.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.
4Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
sTotal precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.

Representative Outfall Status Request
Mecklenburg County
Dear Mr. Doebler:
The Mooresville Regional Office staff have reviewed your November 2017 request for a determination that
stormwater discharge outfall 1 be granted representative outfall status for stormwater outfall 2 and 3. Based on
the information provided and a November 29, 2017 site inspection, we are approving this request. In
accordance with 40 CFR § 122.21(g)(7), you are authorized to sample outfalls number 1 as representative for the
entire site. This approval is effective with the next sampling event.
Please append this letter to your Stormwater Pollution Prevention flan (SPPP) or permit to document that
representative outfall status has been approved. If changes in drainage areas, structures, processes, storage
practices, or other activities occur that significantly alter the basis of this approval, representative outfall status
may no longer be valid. You should either resume sampling at all SDOs, or reapply 'to this office for
representative outfall status based on updated information. If you have any questions or comments concerning
this letter, please contact our Office at [phone].
Sincerely,

Representative Outfall Status Request
4) Detailed explanation about why the outfalls above should be granted Representative Status:
(Or, attach a letter or narrative to discuss this information.) For example, describe how activities and/or
materials are similar.
All outfalls at the facility represent stored used vehicles for the automotive salvage
business. Exposed products at all outfalls include metal and petroleum. Draining,
dismantling, and crushing of automobiles is an activity that only occurs in the
Outfall 002 draining area, but this activity is covered from precipitation. Historic
sample analysis at the outfalls indicate sample results are similar at all three
outfalls.
5) Certification:
North Carolina General Statute 143-Z15.6 B(I) provides that:
Any person who knowingly makes any false statement, representation, or certification in any application, record,
report, plan, or other document filed or required to be maintained under this Article or a rule implementing this
Article; or who knowingly makes a false statement of a material fact in a rulemaking proceeding or contested case
under this Article; or who falsifies, tampers with, or knowingly renders inaccurate any recording or monitoring device
or method required to be operated or maintained under this Article or rules of the [Environmental Management]
Commission implementing this Article shall be guilty of a Class 2 misdemeanor which may include a fine not to exceed
ten thousand dollars ($10,000).
I hereby request Representative Outfall Status for my NPDES Permit. I understand that ALL outfalls are still
subject to the qualitative monitoring requirements of the permit, unless otherwise allowed by the permit
and regional office approval. I must notify DWQ in writing if any changes to the facility or its operations
take place after ROS is granted that may affect this status. If ROS no longer applies, I understand I must
resume monitoring of all outfalls as specified in my NPDES permit.
I certify that I am familiar with the information contained in this application and that to the best of my
knowledge and belief such information is true, complete, and accurate.
Printed Name of Person Signing: _ �f�F 1/YGf3L
Title: ��. f r,-11d�_.._..
(Signature of icant) (Date Signed)
Please note: This application for Representative Outfall Status is subject to approval by the
NCDENR Regional Office. The Regional Office may Inspect your facility for compliance with the
conditions of the permit prior to that approval.
Final Checklist for ROS Request
This application should include the following items:
❑ This completed form.
© Letter or narrative elaborating on the reasons why specified outfalls should be granted representative
status, unless all information can be included in Question 4.
❑ Two (2) copies of a site map of the facility with the location of all outfalls clearly marked, including the
drainage areas, industrial activities, and raw materials/finished products within each drainage area.
❑ Summary of results from monitoring conducted at the outfalls listed in Question 3.
❑ Any other supporting documentation.

Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Ter 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

STORMWATER DISCHARGE OUTFALL (SOO)
MONITORING REPORT
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may request that DWQ waive monitoring of total toxic organics. 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 allowed such a waiver, the
discharger shall sign the following certification statement:
Solvent Management Plan 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 all the provisions of the solvent
management plan included in the stormwater Pollution Prevention Plan."

*Note: Reporting Limit =5.3.
Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.

For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table 11 of Chapter 40 Code of Federal Regulations (CFR) Part 122.

range is the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
