Subject- State Stormwater Management Permit No SW8 880910
IKA Works North America Expansion and Renovation
High Density Wet Detention Pond Project
New Hanover County
Dear Mr Stlegelman
Secretary
TRACY DAVIS
Director
The Wilmington Regional Office received a complete, modified Stormwater Management Permit
Application for IKA Works North America Expansion and Renovation on January 11, 2016 Staff review
of the plans and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Title 15A NCAC 2H 1000 and Session Law 2008-211, as applicable
We are forwarding Permit No SW8 880910 dated January 15, 2016, for the construction, operation and
maintenance of the BMP's and built -upon areas associated with the subject project
This permit shall be effective from the date of issuance until January 25, 2020, and shall be subject to the
conditions and limitations as specified therein Please pay special attention to the conditions listed in this
permit regarding the Operation and Maintenance of the BMP(s), recordation of deed restrictions,
procedures for changes of ownership, transferring the permit, and renewing the permit Failure to
establish an adequate system for operation and maintenance of the stormwater management system, to
record deed restrictions, to transfer the permit, or to renew the permit, will result in future compliance
problems
The following modifications are included and covered by this permit
• The expansion of the project on to the adjoining property, which was previously permitted under
SW8 130724, which has been rescinded effective January 15, 2016 The desire is to now more
closely connect the development on these two parcels
• The expansion of the existing wet detention pond Please note that the original design was based
on the NGVD29 datum which is approximately 1 foot higher than NAVD88, which is why the
elevations appear 1 foot lower than initial permit
• The expansion of the drainage area for the wet detention pond to handle both the additional parcel
as well as offsite runoff that cannot be routed around the stormwater collection system The
offsrte areas have been considered at the maximum build out potential
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings
(OAH) The written petition must conform to Chapter 150B of the North Carolina General Statutes, and
must be filed with the OAH within thirty (30) days of receipt of this permit You should contact the OAH

Rick,
I've had a chance to look through the items submitted on December 30a' in response to the Request for Additional
Information dated December 18, 2105 1 have a few follow up questions / concerns relating to the revised items
submitted in response to Item 1 of this request
Per 15A NCAC 02H 1003(g)(7)
1 It appears that the reported on -site built -upon area as well as the reported onsite and offsite drainage areas
have decreased However, it doesn't appear that the onsite layout or drainage area have changed Can you
explain the decreases? [RAM] It appears that the total onsite and offsite drainage area numbers listed in our DA
map were not changed from our first attempted express submittal (this submittal that wasn't accepted for
review) Our redesign between that time and the accepted express submittal incorporated an offsite bypass
and revised drainage areas based upon offsite permit file reviews However the total drainage areas on the DA
map mistakenly were not updated The revised DA plan sheet is attached
[RAM] The onsite built upon areas are a little more difficult to explain - and I understand your confusion and
desire to make sure this is correct because I'm having a hard time making all the numbers work In an effort to
eliminate the negative numbers in the application on the first submittal, I have now reported all currently

existing BUA at IKA as "existing" - this includes the 1988 permitted BUA of 99,207 5F and the "net add" in 2012
of 11,113 SF for the total existing reported of 110,320 SF I then measured everything in AutoCAD to ensure
100% capture of all proposed BUA I measured again this morning and realized there was a "miss" of pavement
- apparently the edge of pavement line was used to come up with the 59,931 SF of onsite parking I have also
incorporated the loss of 1 parking space in the NW corner by the driveway (NHC Planning required this loss due
to landscaping requirements) Therefore I have revised the onsite parking number to 66,514 SF to reflect the
area to the back of curb This resulted in a required treatment volume slightly higher than what we had
proposed - therefore we regraded the southern side of the pond to gain the additional treatment volume
required Revised application, supplement, BMP calc sheets and the revised plan sheets are attached I'm not
100% sure that you can recreate the numbers previously submitted but I can tell you that the onsite existing
BUA (what is on the ground today) and the onsite proposed BUA in the attached are accurate based upon our
cad files and have been triple checked for accuracy
2 The revised calculations appear to use a composite percent impervious value to determine a single Rv
value This is atypical from the method often used to determine the minimum required storage volume when
multiple design storms are applied Often, the Rv value is determined for each design storm based on the
percent impervious for each portion of the drainage area Please demonstrate that the method used results in
a more conservative approach per 15A NCAC 02H 1008(c)(1) [RAM] Please see the attached revised
calculations showing the Rv associated with a 1" rainfall depth and 1 5" rainfall depth as detailed in previously
submitted accounting of the areas required for each storm This did result in a slightly higher required
treatment volume and the changes discussed in Item 1 above address it A revised SA/DA ratio was also
calculated based on the revised BUA and a composite Rv number and applicable forms/calcs have been
updated
It appears that the permanent pool volume of the pond is being determined based on the current design
standards by excluding the 1 foot depth of sediment accumulation Based on the previous agreement for
expanding this pond, the permanent pool design, including the determination of the permanent pool volume,
was "vested" under the older design criteria Please confirm that permanent pool design criteria (depth,
volume, sediment removal) are consistent with one set of guidance - either the older design criteria or the new
design criteria [RAM] Please see the revised calculations and supplements showing the revised permanent pool
volume with removal of the sediment storage I zeroed out the sediment storage in the calculations to reflect
this change This also resulted in a change to the forebay size, the revised plan sheet showing the larger forebay
is attached for your review
I'll be happy to put these items into a formal request for additional information, if that would be helpful Please let me
know if you have any questions
Thanks)

Rick,
As I was writing this e-mail, I thought I would call to discuss I am battling a cold so my head is a bit foggy and it seemed
easier to talk through this than trying to write it down, but you were away from your desk and the system did not allow
me to leave a voice mad message On that note, here it goes
Is the 17 6% considering the entire pond DA or just for the contnbutmg DA? In my letter, I was trying to advise that the
forebay only needs to be sized for the contributing drainage area If I remember correctly, there is a portion of drainage
area that is previously permitted to directly discharge into the pond without a forebay That is why I referred you to that
section of the BMP manual, to help design a forebay for just the contributing drainage area Depending on how the
numbers work out, I would just write underneath the "error" a justification that the forebay is only sized for the new
contributing drainage area and that the remaining portions of the pond are previously approved without a forebay
I hope this makes sense Please let me know if you have anymore questions

Chnstine-
I hope you had a nice Christmas and are ready for a Happy New Year
One quick question on your comment letter - first, 1 did have to make some revisions to our permanent pool/temporary
pool volumes After I did that, my forebay size came down to 17 6% Before I submit with 17 6% and say that this is
"approximately 20%" as required in the BMP manual, I wanted to get your opinion I know the supplement says 18%-
22%, trying to determine whether 17 6% is close enough since it would roundup However the cell in the supplement 1!
protected and rounds to the tenths and therefore reports insufficient volume
Last on your forebay comment -you mentioned sizing multiple forebays We only have a single forebay -however there
is existing drainage area on the old IKA site that bypasses the forebay (previously permitted as such) - are you indicating
you want me to size the forebay taking this existing area that bypasses the forebay out of those talcs?
I will have the revised information to you before noon tomorrow - maybe even today depending on the answers to the
above
Thanks for your continued assistance

Response Please see the attached data table, presented as you
have presented yours above It also include individual
breakdowns of how the totals were derived The 1" and 15"
storm data has been revised according to this data and the
revised pond supplement and calculations are also attached
Please re -consider how the impervious area is presented to avoid
the negative numbers This is an uncommon way of presenting the
information and adds confusion to a project that already has
several different aspects If the goal is to present the amount of

originally issued permit that can be accomplished through the
existing BUA row, with a discussion in the narrative, or with more
detailed information presented in a separate table
Response The negative numbers have been removed from the

This is the permanent pool volume (85,013 CF) mmus the
sediment storage volume (22,574 CF)
d Please provide calculations demonstrating that the forebay has
been sized to handle the respective drainage area If necessary,
Section 10 3 3 of the NC BMP manual provides additional
details on sizing multiple forebays

Rick,
As I was writing this e-mail, I thought 1 would call to discuss I am battling a cold so my head is a bit foggy and it seemed
easier to talk through this than trying to write it down, but you were away from your desk and the system did not allow
me to leave a voice mail message On that note, here it goes
Is the 17 6% considering the entire pond DA orjust for the contributing DA? In my letter, I was trying to advise that the
forebay only needs to be sized for the contributing drainage area If I remember correctly, there is a portion of drainage
area that is previously permitted to directly discharge into the pond without a forebay That is why I referred you to that
section of the BMP manual, to help design a forebay for just the contributing drainage area Depending on how the
numbers work out, I would just write underneath the "error" a justification that the forebay is only sized for the new
contributing drainage area and that the remaining portions of the pond are previously approved without a forebay
I hope this makes sense Please let me know if you have anymore questions

Chnstine-
I hope you had a nice Christmas and are ready for a Happy New Year
One quick question on your comment letter - first, I did have to make some revisions to our permanent pool/temporary
pool volumes After I did that, my forebay size came down to 17 6% Before I submit with 17 6% and say that this is
"approximately 20%" as required in the BMP manual, I wanted to get your opinion I know the supplement says 18%-
22%, trying to determine whether 17 6% is close enough since it would round up However the cell in the supplement is
protected and rounds to the tenths and therefore reports insufficient volume
Last on your forebay comment -you mentioned sizing multiple forebays We only have a single forebay- however there
is existing drainage area on the old IKA site that bypasses the forebay (previously permitted as such) - are you indicating
you want me to size the forebay taking this existing area that bypasses the forebay out of those calcs?
I will have the revised information to you before noon tomorrow - maybe even today depending on the answers to the
above
Thanks for your continued assistance

IKA WESTERN EXPANSION
Project #1683-0003 (40)
NEW HANOVER COUNTY, NC
DESIGN NARRATIVE
EXISTING CONDITIONS
The existing IKA site is located on a 4 53 acre site with a wet pond treating the built upon area
The original site was permitted on September 26, 1988 with a major expansion permitted on
January 25, 2012 The 2012 permit modification resulted in a hybrid stormwater permit with
portions of the project area being treated to 1988 standards and remaining portions being
treated to current standards at the time of permitting
PROPOSED PROTECT
IKA Works, Inc's North American Headquarters located in the North Chase Industrial Park in
New Hanover County is proposing to expand their existing facility to the west A 36,000
square foot building addition will be constructed on the western side of the existing building
For connection of the 2 buildings, the existing wet detention pond needs to be modified In
addition to the building expansion, the existing asphalt employee parking lot in front of the
existing building will be modified/expanded, a truck turn -around, loading dock and additional
parking will be constructed on the west side, a loop driveway connecting the expansion on the
western side with the existing facility will be installed, and concrete sidewalks will be installed
in various places around the site for pedestrian access Part of this project is also a
recombination plat which will join 3 parcels of land into a single parcel with revised drainage
easements The project will be contained within the recombined parcel of land having an area
of 8 45 acres
PROPOSED IMPROVEMENTS
This project proposes to fill in a portion of the existing wet pond that currently bisects the lots
proposed for recombination and install a larger pond behind the proposed facility to treat the
runoff from the proposed onsite improvements, the existing onsite built upon area (BUA) as
well as offsite drainage areas and their BUA
Hydrologically and hydraulically the pond is designed to treat the first 1 5" of rainfall from the
BUA installed during the 2012 IKA expansion, the BUA proposed in this expansion and
potential future BUA on 2 parcels located within the drainage area (portions of SW8 000720
and SW8 101018) It is also designed to treat the first I" of runoff from the BUA permitted for
the original IKA site as well as the existing offsite BUA (the offsite BUA was constructed prior
to the rules revisions requiring treatment of the first 15") The proposed pond expansion

geometry is designed in accordance with current rules including the provision of a forebay
(sized for the entire drainage area), littoral shelf and 3 1 side slopes The existing riser will
require minor modifications to maintain a 2-5 day drawdown time for the increased runoff
resulting from the offsite drainage area and proposed BUA The pond bottom elevation and
permanent pool elevation are proposed to stay as designed and permitted in 1988 and
modified in 2012 resulting in a 3' depth
For further clarification of the offsite drainage areas, BUA, rainfall treatment depths, etc please
see the Offsite Drainage Area and BUA figure herein and Plan Sheet 13, DA-101

RE IKA - existing pond revisions
Rick,
Thanks for the e-mail In regards to the SHWT, when there is an established pond or other drainage feature that is in
the vicinity of the proposed BMP, then the argument / justification could be made that the SHWT soil indicators are of a
relic elevation and that the pond or other drainage features have lowered the SHWT to a level at or below the existing
outlet This is assuming that the pond does in fact stay at that elevation and there is no groundwater entering during
times when the SHWT is in play (in other words, the pond doesn't discharge groundwater between rain events)
On to how to design an expanded pond I have reviewed notes on past projects and hopefully have some better and
clearer information for you If you have to increase the pond surface area to handle the additional drainage area and
impervious area, then only the part of the pond that is being expanded needs to meet the current requirements
(forebay, vegetated shelf, slopes, etc) The previously constructed slopes that are not being touched or expanded can
remain as is Now which method of determining the depth of the pond will depend on if you are having to increase the
depth If you are using the previously permitted depth, then you can continue to use the method previously
approved However, if you are having to increase the depth, then the average depth must be used for the entire pond
As for the adjacent permits, these are the ones I came up with
Cape Fear Dialysis — SW8 101018
Cornerstone Baptist Church — SW8 000720
Dominion Park Section I — SW8 940714
I think that covers the properties you are concerned about In reading the follow up e-mail you just sent It probably
would be wise to consider the density allowed per the permit for that residential development (likely 30%)
I will get with Cameron to provide my next available date

Subject IKA -existing pond revisions
Since I know you are going to be discussing upgrades to our existing pond once we increase the BUA coming to it, I
wanted to give you a little more info The existing pond is in a 60' drainage easement The existing top of bank is
roughly 36 and the bottom of pond is 27 Therefore there is 9 vertical feet on each side At 3 1 side slopes, that leaves a
6' "base" in the center (see attached) If we try to get any more depth in this section it will essentially become a v-ditch
with a bottom elevation of 26'
One other thing we didn't discuss but I think needs to be brought up We were proposing to use the same permanent
pool elevations as the existing pond - 30 69' However our SHWT determination showed SHWT to beat an approximate
elevation of 34' Does this come into play at all with our required upgrades?

Subject IKA Submittal date
Christine and Cameron -
We came back yesterday and looked at a couple options for dealing with the offsite drainage and meeting the
requirements as discussed in our submittal meeting We found that by installing a bypass for the undeveloped lot
adjacent to College Road (to our west) we were able to treat what we consider to be the ultimate buildout potential for
the remainder of the offsite drainage area Our assumptions for this ultimate bwldout included using the existing BUA in
the residential section and a 50% allocation for the remaining portions of the 2 parcels that front Northchase Parkway
SE That determination Is made considering zoning, front and side yard setback requirements and landscaping
requirements (including streetyard buffers) However we would still like to do file reviews on the adjacent
developments to ensure using the existing BUA is suitable In those developments
All that said, I don't see any reason why this will not work and IKA wants to get back on the submittal calendar as soon
as possible If submittal dates are already into December, there Is no reason we will not be able to have this all ironed
out and detailed in our plans and calculations by that time

Subject RE signature authority
Rick,
There is no standard language but the letter has to either be general enough that it allows Mr Hardin to sign any
documents on her behalf (it doesn't specify the type of document) or the letter can specifically call out what he can sign
on her behalf But if the letter gets too specific and calls out that he can sign on her behalf for erosion control approvals
(as an example), I can't take it since stormwater permits are listed
Hope that helps)

The person at IKA (Refika Bilgic) who can sign documents (according to the Secretary of State website) for them is out of
the country until October 26 (IKA is a German company and she is out of the country a lot) Is there some standard
language you require when she is giving someone else at the company signature authority for the stormwater
permit? Bob Hardin is going to sign on her behalf - he has signature authority for financial and banking documents but I
don't think that is good enough for you

Got your message We do not have room on our 8-acre +/- site to treat the runoff from a 12-acre +/- offsite drainage
area -and still have room to develop the site to meet our client's needs So we are going to look to bypass the offsite
drainage areas as shown in the attached There are 2 cross pipes that bring runoff from north of Northchase Parkway to
the NCDCT ditch along our frontage We plan to divert this flow around our system in a conveyance ditch We also plan
to install a conveyance ditch along our western boundary to capture any runoff from the parcel west of ours Both of
these ditches will flow into a proposed pipe system, isolated from our onsite collection system, and discharge into the
downstream conveyance in the same location as the existing pond outlet We will provide a drainage easement along
the entire path of the bypass for future access and maintenance
Please let me know if this will address the concerns for offsite drainage and limit our pond design criteria to treatment
of onsite runoff only
Thank you -

Project #1683-0003 (40)
NEW HANOVER COUNTY, NC
DESIGN NARRATIVE
PROPOSED PROTECT
IKA Works, Inc's North American Headquarters located m the North Chase Industrial Park in
New Hanover County is proposing to expand their existing facility to the west A 36,000
square foot budding addition will be constructed on the western side of the existing building
In addition the existing asphalt front employee parking lot currently containing 52 parking
spaces will be expanded to accommodate 33 additional spaces for a total of 85 parking spaces
A loop driveway will also be installed connecting the existing facility with the western part of
the tract along with an employee asphalt parking lot containing 20 spaces, concrete sidewalks
and an asphalt truck parking/loading/unloading area on the western side of the proposed
expansion This project will be contained within the existing parcel of land having an area of
4 53 acres
PROPOSED IMPROVEMENTS
This project proposes to reconfigure the existing wet detention pond and bringing the new
section up to current standards to treat all of the onsite BUA installed/proposed since the
original development in the late 1980's This includes a provision of a forebay and littoral
shelf, a temporary water quality volume sufficient to treat the 1 5" runoff volume from the
permitted site using the newly proposed average depth and construction of a new spillway
system for meeting the 2-5 day detention requirements of NCDENR

IKA Works, Inc.
Project #1683-0002 (40)
DESIGN NARRATIVE
PROPOSED PROTECT
IKA Works, Inc's North American Headquarters, located in the Northchase Industrial
Development Park of New Hanover County, is proposing to expand their current facility with
an additional building and parking on the adjacent Dombrowski property The proposed
building is anticipated to be approximately 30,000 total square feet In addition to the new
building a new front parking lot will be constructed and contain 65 parking spaces, a rear
parking lot will be constructed to accommodate an additional 21 parking spaces and 14 -
18'x60' trailer parking spaces for a total of 100 parking spaces This project will be contained
within the two adjacent tracts of land having a total area of 3 92 acres
EXISTING SITE
The project address is 2701/ 2717 Northchase Parkway SE in Wilmington, NC The project is
located directly west of the existing IKA office and butler building 1'he area is currently
vacant with intermittent fields and wooded areas within an industrial park
The site drains to the west, toward an existing ditch system along Northchase Parkway and
ultimately to Smith Creek Smith Creek is classified as a C, Sw stream (Index 18-74-63) The
New Hanover County SCS Soil Survey indicates that the soils on the parcel are a mixture of
primarily Leon (Le) and Murville (Mu)
There are no existing utilities present on the site
PROPOSED IMPROVEMENTS
This project will be permitted as a high -density project with one wet detention pond to be used
for stormwater treatment Wet Pond #1 will capture runoff from the proposed project site All
runoff will be piped to this stormwater facility
Me proposed pond was designed to treat the proposed built -out condition of a 3 92 acre
drainage area with a 59 8% composite impervious area The wet pond treatment volume was
calculated using the 15 " design runoff volume required by the NCDENR coastal stormwater
regulations Ihis volume will be controlled and released over a 2-5 day period In addition,
the pond was designed to reduce peak flows to pre -developed conditions for the 2-, 10-, and
25-yr storm events The pond was designed with a surface area designed for 90% TSS removal

The Wet Pond will outlet to an existing ditch draining to the existing pond on the adjacent IKA
property

MAP INFORMATION
Map Scale: 1:1,170 if printed on A size (8.5" a 1 V) sheet.
The soil surveys that comprise your AOI were mapped at 1:15,840.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil line
placement. The maps do not show the small areas of contrasting
soils that could have been shorn at a more detailed scale.
Please rely on the bar scale on each map sheet for accurate map
measurements.

Map Unit Descriptions (IKA Adjacent
Parking)
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the landscape,
however, the soils are natural phenomena, and they have the characteristic variability
of all natural phenomena. Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if ever, can be mapped without including areas of other taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used.
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments
on the map provides sufficient information for the development of resource plans. If

Custom Soil Resource Report
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas
An identifying symbol precedes the map unit name in the map unit descriptions Each
description includes general facts about the unit and gives important soil properties
and qualities
Soils that have profiles that are almost alike make up a soil senes Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other characteristics that affect their use On the basis of such
differences, a soil series is divided into sod phases Most of the areas shown on the
detailed soil maps are phases of soil series The name of a soil phase commonly
indicates a feature that affects use or management For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series
Some map units are made up of two or more major sods or miscellaneous areas
These map units are complexes, associations, or undifferentiated groups
A complex consists of two or more sods or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps The
pattern and proportion of the soils or miscellaneous areas are somewhat similar in all
areas Alpha -Beta complex, 0 to 6 percent slopes, is an example
An association is made up of two or more geographically associated sods or
miscellaneous areas that are shown as one unit on the maps Because of present or
anticipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar Alpha -
Beta association, 0 to 2 percent slopes, is an example
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them Alpha and Beta soils, 0 to 2 percent slopes, is an example
Some surveys include miscellaneous areas Such areas have little or no soil material
and support little or no vegetation Rock outcrop is an example
