Subject: EXT: Unison Engine Components - NOI for NCG03 Permit Coverage

Michelle,
I was out of the office for a few weeks, and I'm catching upon permits. I'm working on the COC for Unison Engine
Components in Asheville now (which will be issued in conjunction with a rescission of the current NCGNE1040 No
Exposure Certification).
I need to enter outfall points into our database, but the question on the NOI about how many stormwater outfalls there
are at this facility is blank. How many discharge points do they have? I see one obvious one on the attached site plan
map, but the sheet is very small, and I can't clearly see others.
Thank you,
Bethany

We received an NOI from Unison Engine Components in Asheville for coverage under NCG03. They have been under a

In further review, I want to be sure that you are aware that Laura granted regulatory relief from tiered sampling in 2014
for this facility under permit NCG030543. It appears that NCG030000 is at the same address. Bottom line, it's likely a
good thing they are getting the entire address under a SW permit and I'm not sure why they would even have a NE at a
permitted facility (?)
Let me know if you need anything else.

Dear Mr. Meguiar:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
WILLIAM E. VINSON, JR.
Interim Director
The Asheville Regional Office staff have reviewed your request dated March 16, 2018, for a
determination that stormwater discharge outfall (SDO) OS5 be granted representative outfall status for
stormwater outfalls OSI, OS2, OS3, OS4. Based on the information and maps provided and a site
inspection on February 20, 2018, we are approving this request. In accordance with 40 CFR
§122.21(g)(7), you are authorized to sample outfall number OS5 as a representative outfall. This
approval is effective with the next sampling event. We also want to remind you that the permit still
requires Qualitative Monitoring be performed at all _SDOs, regardless of representative status.
Please remember that any actions you initiate in response to benchmark exceedances as directed in the
tiered response provisions of your permit must address all drainage areas represented by OS5, where
appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (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 Shawna Riddle or me at 828-296-4500.

REQUEST FORM a �% F
If a facility is required to sample multiple discharge locations with very similar stormw-bW the
permittee may petition the Director for Representative Outfall Status (ROS). DWQ may grant �e
Outfall Status if stormwoter discharges from a single outfall are representative of discharges from le
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 DWQ
approval. The approval letterfrom DWQ must be kept on site with the facility's Storm water Pollution
Prevention Plan. The facility must notify DWQ in writing if any changes affect representative status. R{�„

Shawna Riddle from local Asheville NCDEQ office was onsite February 20, 2018 for storm water
inspection for both buildings (401 and 502).
Buildine 401 i401 Sweeten Creek Industrial Parki:
The property is bordered on the north by a tributary to Sweeten Creek and on all other downgradient
side by industrial properties. The manufacturing operations are enclosed in buildings covered by a roof
and the surrounding vehicle operation areas are paved with asphalt and gravel. Trialers are parked in
the southern portion of the property (lot leased to UPS). Shipping and receiving areas are located on the
south and southwest corner of building 401. Employee parking is the west of building 401. Employee
and visitor parking are also present in an asphalt paved, unfenced lot to the north of building 401. The
remainder of the property consists of landscaped property (grassed yard) north of building 401. Rain
water falling on the property is primarily collected in the catch basins or drainage ditches and is
discharged offsite to roadside ditches north and northeast of the plants which subsequently discharge to
the Sweeten Creek tributary.
Building 401 site is approximately 8.6 acres in area and is currently occupied by a one-story facility with
about 102, 051 square feet of office, manufacturing and warehouse space. A one-story chemical
building (2,170 sq, ft.) is present south of building 401. The plant is bordered to the south, west and
north by pavement, consisting of parking lots, loading docks, or driveways. The basic layout of the plant
is such that the truck loading and unloading docks are out the south and southwest sides of the building
and the administrative offices are on the north side of the building. Most of the plant space is devoted
to manufacturing activities and product storage.
Thestormwater runoff from roof drains, the above ground storage tank area, loading docks, material
storage areas and surrounding driveways or parking lots is generally collected by catch basins located on
the around the perimeter of the plant. The catch basins on the south, east and north side of the plant
discharge to Outfall 001. The catch basins on the east and northeast side of the plant discharge to
Outfall 002. One catch basin on the south side of the plant is routed to the adjoining UPS property
(shared outfall) and discharges to Outfall 005.
Please note that Outfall 003, 004 and 006 drain other portions of sweeten creek industrial park not
occupied by GE Aviation.
We are wanting to move to ONLY sample from outfall q1.
Outfall #2 borders with another facility and only grass and parking lot.
Outfall #5 is a shared outfall with UPS next door due to storm drain leading into their storm drain. The
tank located near the storm drain has adequate secondary containment and truck operators have been
instructed to use a drain cover during water removal from tank.
Shawna Riddle from Asheville Local NCDEQ office has advised from her site visit that Outfall #1 would be
a representative outfall for both.

Building 502 J502 Sweeten Creek Industrial Park):
Very little exists at this location would cause a concern related to stormwater runoff. However, this
120,000 SF building does have loading and unloading operations and parking on the southern and
eastern sides. Therefore, in an abundance of caution, this site decided to permit building 502 rather
than maintain exemption. The exposed pollutants would be limited to vehicle traffic and
unloading/loading operations.
Building 502 should be and would qualify for a no exposure certification. Our parent company of GE likes
to air on the side of caution and has advised us to stay permitted under the General Storm water Permit.
Outfall #5 is the only outfall that would see any action due to the covered areas for trash, recycling and
waste. Also, due to the amount of new machines we are installing, occasionally there might be packing
material staged outside for removal.
Shawna Riddle from Asheville Local NCPEQ office has advised from her site visit that Outfat! ##.5 would
be a representative outfall for all others due to no activity outside.
