If a facility is required to sample multiple discharge locations with very similar stormwater discharges, the
permittee may petition the Director for Representative Outfall Status (ROS). DEQ may grant Representative
Outfall Status if stormwater discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply.
If Representative Outfall Status is granted, ALL outfalls are still subject to the qualitative monitoring
requirements of the facility's permit —unless otherwise allowed by the permit (such as NCG020000) and DEQ
approval. The approval letter from DEQ must be kept on site with the facility's Storm water Pollution
Prevention Plan. The facility must notify DEQ in writing if any changes affect representative status.
For questions, please contact the DEQ Regional Office for your area (see page 3).

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.
See Attached Narrative
5) Certification:
North Carolina General Statute 143-215.6 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 DEQ 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.

Subject RDU5 Representative Outfall Narrative ERM
Outfall 004 and Outfall 012 does not contain industrial activity, activities in these areas are
restricted to employee parking and therefore sampling should not be required.
Outfalls 001, 002, and 003, 005, 006, 007, 008, 009, 010, 011 each represent the industrial
activities that is occurring within each of the respective drainage areas. In order to monitor
pollutants that may be present at the facility during industrial activities. Up until recently Outfall
005, 006, 007, 008, 009, 010, and 011 were not identified because access to the outfalls is unsafe
during the growing season due to vegetated overgrowth. Also, site drainage plans were not
available when the permit was issued.
Outfall 001 is representative of 001, 005, 006, 007 because 001 has a greater potential for
industrial use impacts due to higher use in the "Mobile Fueling Area" while having similar uses
(loading docks).
Outfall 002 is representative of 002 and 008 because 002 has a greater potential for industrial use
impacts due to higher use in the "Mobile Fueling Area" while having similar uses (loading docks
and truck parking).
Outfall 003 is representative of 003 and 009 because 003 has a greater potential for industrial use
impacts due to higher use in the "Mobile Washing Area" while having similar uses (loading docks
and truck parking). Furthermore, Outfall 009 and the catch basin draining to Outfall 009 cannot be
sampled due to safety access issues.
Outfall 010 is representative Outfall 010 and 011 because 010 has a greater potential for industrial
use impacts due to higher use in the Fire Pump House Area while having similar uses (truck
entrance area).
