RE: Application for Representative Outfall Status
CPI USA North Carolina LLC — Southport Facility
Dear Mr. James:
Enclosed please find two (2) copies of the Representative Outfall Status (ROS) request form for
the CPI USA North Carolina LLC - Southport facility. The ROS form requests utilization of the
single combined outfall (Outfall 001C), through which all stormwater runoff from the facility
flows. The sole exception is stormwater runoff discharged in accordance with NPDES Permit
0065099, which treats stormwater associated with fuel pile runoff and discharges through a
forced main. Some stormwater runoff from off site flows through Outfall 001C, however, there
is no additional industrial activity associated with this flow.
Analytical data from 2017 is enclosed with the ROS request form along with the data table
submitted with the 2014 renewal application, however, "No Data" is indicated on the form since
the ROS request is based on common flow to combined Outfall 001C, which receives
stormwater runoff from all outfalls permitted under NPDES Permit NCS000348.
Should you have any questions or require additional information, please contact me at (910)
343-6711 or Tim Monroe, P.E. at Leaf Environmental & Engineering, P.C. at [phone].

(Or, attach a letter or narrative to discuss this information.) For example, describe how activities and/or
materials are similar.
All outfalls discharge through combined Outfall 001C (see Figures 3 & 4).
No significant off -site industrial activity disc arges stormwater runoff
into thegrass-lined drainage swales that surround CPI -South ort property
(see Figure 2). Original permitted outfalls and industrial activities
exposed to stormwater are shown on Figure 1-2.
With the exception of fuel storage piles, all stormwater runoff from
the site discharges through Outfall 001C. Stormwater runoff from fuel
storage piles is discharged under NPDES P rm' N 0065099 S ormw ter
inflow from the grass —lined drainage ditch NW of Outfa11 001C i ex
to to no additional indiiGfirial a�.tivit�,
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
r' 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.
Printed Name of Person Signing: Virginia Grace

RE: Application for Representative Outfall Status
CPI USA North Carolina LLC — Southport Facility
Dear Mr. James:
NA 2 �
1 2018
BY
Enclosed please find two (2) copies of the Representative Outfall Status (ROS) request form for
the CPI USA North Carolina LLC - Southport facility. The ROS form requests utilization of the
single combined outfall (Outfall 001C), through which all stormwater runoff from the facility
flows. The sole exception is stormwater runoff discharged in accordance with NPDES Permit
0065099, which treats stormwater associated with fuel pile runoff and discharges through a
forced main. Some stormwater runoff from off site flows through Outfall 001 C, however, there
is no additional industrial activity associated with this flow.
Analytical data from 2017 is enclosed with the ROS request form along with the data table
submitted with the 2014 renewal application, however, "No Data" is indicated on the form since
the ROS request is based on common flow to combined Outfall 001C, which receives
stormwater runoff from all outfalls permitted under NPDES Permit NCS000348.
Should you have any questions or require additional information, please contact me at (910)
343-6711 or Tim Monroe, P.E. at Leaf Environmental & Engineering, P.C. at [phone].
Sincerely,
CPI USA NORTH CAROLINA LLC
