Representative Outfall Status Request
Linamar
Buncombe County
Dear Mr. Grein:
The Asheville Regional Office staff have reviewed your request dated December 4, 2017, for a
determination that stormwater discharge outfall (SDO) 001 be granted representative outfall status for
stormwater outfalls 002, 003 and 004. Based on the information and maps provided and a site inspection
on April 26, 2018, we are approving this request. In accordance with 40 Cf'R § 122.2 1 (g)(7), you are
authorized to sample outfall number 001 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 001, 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.

1.2 Narrative Description of Facility
The LNC Arden Facility consists of three main operations buildings, The Mitchell Building (Building 1), The
Pisgah Building (Building 2), and Building 3. Industrial activities associated with manufacturing of automotive
components occur within these three buildings. The three building are surrounded by concrete and asphalt areas.
Employee parking areas are located to the south of the Mitchell Building. There are two guard stations, one to
the north which provides access to Long Shoals Road, and one to the east which provides access to U.S.
Highway 25. Lake Julian surrounds the facility to the south and west. In general, wooded areas provide a
riparian buffer between the facility's industrial activities and Lake Julian.
13 Site Map
There are four drainage areas and four corresponding stormwater outfalls at the facility. These areas, which
were identified based on visual observations, review of available drawings, and discussions with facility
personnel, are shown in Figure 1-2. Figure 1-2 is a site layout diagram of the facility. The diagram indicates the
property boundary, the stormwater discharge outfalls, on -site and adjacent surface waters, industrial activity
areas, drainage features and structures, drainage areas for each outfall, direction of flow in each drainage area,
industrial activities occurring in each drainage area, buildings, existing BMPs, and impervious surfaces. Table

Drainage Area 1 (DA1) drains the industrial portions of the facility, and some inactive parts of the
facility. Structures located in DAl include: Mitchell Building, Pisgah Building, Waste Shed, and the
eastern portion of Building No. 3. The Prab Room (coolant recycling) is located adjacent to eastern wall
of the Mitchell Building and a loading/unloading area under a canopy is north of the Mitchell Building.
The Wash Shed, used for washing dirty vehicles and equipment, is located to the east of the Pisgah
Building. The Waste Shed, between the Mitchell and Pisgah Buildings, stores metal chips in rolloffs and
used oils/coolants in totes under a canopy. A coolant tank stores coolant drained from metal chips in the
rolloffs outside of the canopy. Duke Energy transformers are located north of the Waste Shed, surrounded
by chain -link fencing. The eastern guard station and associated vehicle access roadways and employee
parking areas are also within DAL The total surface area of DA 1 is approximately 44.1 acres, of which
approximately 24.9 acres consist of impervious surfaces (e.g., buildings, roads, parking lot).
The land in DA 1 drains to catch basins and then to a retention pond located just southwest of the Pisgah
Building. As shown in Figure 1-3, a network of underground storm sewers collect stonnwater from the Mitchell
Building and discharge to the retention pond adjacent to Lake Julian. After flowing to the retention pond,
stormwater from DA I flows into Lake Julian.

1.4 Potentially Exposed Areas
Figure 1-2 shows the facility drainage map highlighting areas where potentially exposed materials are present.
1.4.1 Drainage Area 1
1. Mitchell Building Building 11—The Mitchell Building houses equipment used for machining cast
iron engine blocks and related parts. Most of the manufacturing equipment is comprised of
machines that are cooled using a recirculating liquid coolant. Other manufacturing machines are
hydraulically operated such that they contain systems that normally contain hydraulic fluid. The
Prab Room, attached to the eastern wal l of the Mitchell Building, contains a 2,000 gallon capacity
tank for coolant recycling. The Prab Room has a secondary containment (25 ft x 30 ft x 0.5 ft) with
a capacity of 2,805 gallons, which is greater that the capacity of the coolant recycling tank. In
addition to the coolant recycling tank, typically 500 to 1000 gallons of coolant, hydraulic fluids,
and other liquids are stored in drums, totes, and other containers on secondary containment pallets
within the Prab Room. The Mitchell Building is fully enclosed except for the covered waste
storage area north of the facility which is currently not in use. Floor drains located in the building
are capped with plugs. Spills or leaks would be contained on the concrete floor within the confines
of the building's walls, such that operations within the building do not present potential for
stormwater pollution.
2. Pisgah Building (Building 2) — The Pisgah Building houses equipment used for machining of
engine gears and pinions. Most of the manufacturing equipment is comprised of machines that are
cooled via a recirculating liquid coolant. Other manufacturing machines are hydraulically operated
such that they contain systems that nomially contain hydraulic fluid. Manufacturing machines are
located in the southern portion of the Building, and the northern portion of the building is used
primarily for storage. Coolant, hydraulic fluids, and other fluids are not stored in the Pisgah
building. The Pisgah Building; is fully enclosed. Spills or leaks would be contained on the concrete
floor within the confines of the building's walls, such that operations within the building do not
present potential for stormwater pollution.

Building 3 - Building 3 is used for storage of 55-gallon drums and totes (275 and 300 gallon
capacity) of oil products and other raw materials. There are two primary storage areas separated by
a chain link fence within Building 3 - the tool crib and the Pisgah Building storage area. The tool
crib inventory, located in the southern portion of Building 3, typically contains between 5,000 and
7,000 gallons of oils/coolant used in the Mitchell Building. The Pisgah Building oil storage area, in
the west central portion of Building 3, typically contains 2,000 to 3,000 gallons of oils/coolant
primarily in 55-gallon drums. Spills or leaks would be contained on the concrete floor within the
confines of the building's walls, such that operations within the building do not present a potential
for stormwater pollution. Spill kits are located within the building near doorways. Floor drains
within Building 3 are capped with plugs. As such, Building 3 present a low potential risk of
stormwater pollution.
4. Transformers (owned and operated by Duke Energy) — The transformers are located north of the
Waste Shed confined behind chain -link fencing. LNC personnel do not have authorized access to
the transformers. In the event of a spill or leak of dielectric fluid from a transfomer, Duke Energy
would be immediately notified in accordance with LNC Arden Facility's SPCC Plan, and Duke
Energy would be responsible for containing and cleaning up the spill or leak.
Metal Chips Storage (adjacent to Pisgah Building) — Four metal rolloffs containing metal chips are
stored for shipment off -site, under a canopy designed to prevent precipitation from contacting the
chips in the northwest corner of the Pisgah Building. The area under the canopy is curbed and
sloped to a sump, to prevent metal chips and metal chip leachate from flowing into a nearby
stormwater catch basin, and to collect any precipitation which may blow onto the pad beneath the
canopy. Metal chip leachate and/or precipitation collected in the sump is pumped to a storage tank
within the Pisgah Building. Based on the sloped floor and canopy cover, operations that occur
within the metal chips storage area do not present a potential for stormwater pollution.
6. Waste Shed — The Waste Shed is located between the Mitchell and Pisgah Buildings and stores
used oil/coolant in totes and metal chips in rolloff dumpsters. Between 2,500 to 5,000 gallons of
used oil/coolant is typically stored in the waste shed. When used oil/coolant volumes reach
approximately 5,000 gallons, the totes are picked -up and disposed off -site. The waste shed is
covered, contains a floor sump and has a concrete berm perimeter for containment. Oil/coolant
leaks/spills and/or collected precipitation, flows via gravity to the sump beneath the canopy. When
the sump is full, its contents are pumped to a coolant storage tank located outside the canopy on a
concrete pad. This storage tank is equipped with secondary containment. As such, the metal chips
and oil/coolant storage area poses a minimal potential risk of stormwater pollution.

Loading/Qnloading and Trash Rolloff (under a canopy) — An area historically used for storing a
trash rolloff, and for loading and unloading materials, equipment, and containers of coolant,
hydraulic oil, and other oils is located tinder a canopy adjacent to, and north of, the Mitchell
Building- This area is currently not in use. This area poses a minimal potential risk of stonnwater
pollution. Only in the event of a spill during loading or unloading of totes or drums, which is
currently not performed in this area, would this area pose a risk as a source of stormwater pollution-
8. Wash Shed — The covered wash shed is attached to the northeast corner of the Pisgah Building.
The Wash Shed, used to clean dirty or oily equipment, is sloped towards a drain in the center of the
shed. The captured wash water is then pumped to totes (275 or 300 gallons) located inside the shed
for storage. The stored wash water is then pumped to a tanker truck for disposal offsite. As such,
there is low potential for stonnwater pollution from this source.
9. Access Roadways and Parking Lots — Facility access roads and parking areas only experience
light, non -industrial traffic. As such, there is low potential for stormwater pollution from these
sources.
10. Air Compressor— Air compressor located outside of Bay Door 5 of Mitchell Building. In the event
of a spill or leak of oil, proper channels would immediately be notified in accordance with LNC's
SPCC Plan and Maintenance, or designee, would be responsible for stopping the spill or leak.
1.4.2 Drainage Areas 2,3 and 4
While DA2 and DA4 do contain impervious surfaces, they are located in nonindustrial portions of the facility
except for DA3. As such, there is little potential for stonnwater pollution in these areas.
DA3 contains the western portion of Building 3 in which contains a portion of the tool crib and Pisgah Building
storage areas. Oils/coolants are stored under the Building 3 western roof in 55-gallon drums and totes. Spills or
leaks would be contained on the concrete floor within the confines of the building's walls, such that operations
within the building do not present a potential for stormwater pollution.

Dear Mr. Cranford:
The purpose of this letter is to request a Certificate Of Coverage (COC) to
discharge stormwater under N.C. General Permit NCG030000 for Stormwater
Discharge from our metal parts plant located at 2169 Hendersonville Road,
Arden, North Carolina.
Attached, please find the following:
1. Check for $100 made payable to NCDENR.
2. The completed Notice Of Intent form.
3. A site diagram showing: (a) outline of drainage areas, (b) stormwater
management structures, (c) location of stormwater outfalls corresponding
to the drainage areas, (d) runoff conveyance features, (e) areas where
materials are stored, (f) impervious areas, and (g) site property lines.
4. Copy of USGS quad sheet showing the facility location.
We anticipate a gradual startup of operations which will begin on or about
January 15, 2012. Linamar plans to have a site specific Stormwater Pollution
Prevention Plan implemented by the date of startup. We understand that
NC DENR will issue a Certificate Of Coverage within ten (10) business days

Hi Bill -
Please issue the COC.
Overall, our preferred process would be for you to issue the COCs without requiring a specific RO recommendation and
we will bring them into our inspection rotation. I believe Roger Edwards had communicated the same request
previously.
Regarding #2 below, this email does not acknowledge the status of outstanding complaints. I'd prefer if that stipulation
was not included in future emails, if such emails continue to be required. I don't understand why a complaint should
prevent a facility from receiving coverage under a permit. Are we talking about complaints in the BIMS Public portal?
Regards,
Chuck

Chuck Cranford, Asheville Regional Office:
Please review the attached NOI application with the objective of responding to me with a recommendation to issue the
permit. I recognize that you may not visit each new permittee during this NOI review, but it affords you the opportunity
to log the permit into your regional database and add the facility to a future monitoring and compliance visit schedule.
Therefore, your recommendation now to issue the permit serves as your acknowledgement that (1) the facility is located
in your region, (2) that there are no current complaints outstanding about the facility that have not been dealt with, and
(3) that the facility may ultimately be inspected by the regional staff. I've also attached a scanned copy of the NOI and a
location map for your review.

If you need any more info, give me a call. If you could send me a recommendation to issue the permit by 04/06/2012,
I'd appreciate it, so I can issue their COC. I cannot issue the permit until the respective regional office reviews and
comments back to me with a recommendation to issue the permit.
Thanks
