Good Afternoon Sam,
I completed my review of the stormwater package delivered to our off -ice on December 1, 2005.
Following is a list of comments and questions that need to be addressed before we can issue a
stormwater permit:
(1) Drainage Area "B" shows an 18-inch PVC pipe that captures the entire roof area, 40,000 sq.ft.;
and then discharges into the subsurface stone bed at a single point. As weViscussed in our
meeting on Tuesday, this will definitely be a problem. The flow from this pipe must be diverted into a
properly designed manifold. Another option would be to divert the runoff into a separate
treatment system.
(2) Typical detention time for wet ponds is 2-5 days; draw down time for infiltration systems is 5
days or less. The outlet pipes for each of the stone beds will act as a drawdown devices in the
event the soils cannot handle the hydraulic loading. To be consistent with the rules, revise the outlet
pipes to draw down in 5 days, or less. Show details and provide calculations.
(3) Grassed areas "B" and "D" should have signs erected that indicate "No Traffic Area"; otherwise
these areas may be compromised by heavy traffic.
(4) Provide runoff volume in cubic feet for overflow from area "E". It's not clear that the overflow
from area "E" will enter the stone bed. Is this practical? Would yard inlets, as shown for B &
E, work better for this system?
(5) What is -the purpose for yard inlets in Area "B"? Will the overflow from area "B" erode the
sodded area? Explain
(6) Porous Concrete inlets for area "E" should be identified and labeled on plans with dimensions.
(7) "Area E". shows a "gravel only phase 1 ". It appears this area drains into the porous concrete
inlets; this could be a constant maintenance problem; please address.
(8) The stormwater narrative, page 5, Section F, states that 5290 sf of detention area would be
required in the event the proposed treatment systems fail. The correct SA/DA calculation for
wet detention ponds would actually require between 10,000 and 17,000 square feet (depending on
certain variables) for the proposed site conditions. It appears that adequate space is available
in drainage area "F", but the owner should be made aware of this requirement and the plans
should be revised to show the contingency area for a wet pond.
(9) From the summary table on page 6:
- Surface area of stone for Area "B" reads 3700; it should be 6700
- The table adds Stone storage at 42% voids and something called "Surface Storage" to get the
Total Storage Provided. This table and this calculation should be amended to delete
"Surface Storage" from the calculation. Grassed/Sodded/Vegetated type areas on a site are considered
good BMP's but are not included in any storage calculations.
(10) Stormwater narrative, Page 6, Section 6 regarding observation wells is unclear; please clarify.

Quick Stai Industry Bldg - Lot 4 - Beaufort County file:///Y:/Quick%2520Start%2520industry%2520B1dg%2520-%25...
(11) Detail for 12-inch yard inlets is missing from detail sheet. Purpose for yard inlets in system "B"
is unclear; area "E" might be appropriate: please show details and explain.
Sam, the O&M Agreement needs some work; we can discuss by phone. I will try to draft the
permit early next week. Please get the revisions to me asap, Thanks.

Dear Mr. Spruill:
Alan W. Klimek, P.E. Director
Division of Water Quality
This office received your Stormwater permit application and plans for the subject project on
October 3, 2005. By letter dated October 12, 2005, 1 requested additional information to complete the
application. Al Hodge and 1 met with Sam Jarvis and Bill Gwinn at this office on October 19, 2005 to
discuss the information we requested and to resolve any remaining permit issues. I have reviewed the
modified plans and specifications submitted to our office on October 31, 2005. The following items must
be addressed before we can issue the stormwater permit:
(1) Please submit (2) complete sets of plans; including Title Page, Vicinity Map, Topo, Site Layout
showing all development & stormwater controls, all detail sheets. (Do not need building plans for
plumbing, -electrical, mechanical, structural, etc.)
(2) Provide all stormwater calculations for each drainage basin and each control system; including
storage volume required, storage volume provided, depth & surface area required & provided,
draw down times for each control system.
(3) Details from the October 3 submittal package indicated that the stone storage bed would be
placed parallel to, and beneath, the asphalt parking lot. This -is a design problem that was
discussed in our October 19 meeting. The stone storage bed must be constructed level, while the
finished parking lot surface may be sloped. Provide details that show the elevations of the stone
storage bed in relation to the paved asphalt parking lot.
(4) Please provide detailed soils report for this site. Discuss soil permeability, seasonal high water
table, drainage conditions and any site constraints that are evident. Explain how the proposed
control systems are designed to overcome any constrains due to site conditions (See item no. 4a
from my October 12 letter)..
(5) Provide scaled detail of observation wells and show specific locations on site plan. The
stormwater permit will require water quality sampling to evaluate the effectiveness of the control
systems. Will the observation wells serve a dual purpose as water quality sampling stations?
Where will the effluent sampling stations be located?
(6) Item No.7 regarding subsurface drains has not been adequately addressed.

Subject: Stormwater Review SW7051002
Industry Ready Building, Lot No. 4
Beaufort County
Alan W. Klimek, P.E. Director
Division of Water Quality
This office received a Coastal Stormwater permit application and plans for the subject project on
October 3, 2005. A preliminary review of your project indicates that before a State Stormwater permit can
be issued the following additional information is needed.
(1) The stormwater application form SWU-101, dated January 1998 is outdated; the current
stormwater application form is SMU-101, Version 3.99. This version can be found on our Division
web page, or we have hard copies available at this office. Please use current application forms in
the future.
(2) Page 2 of the application indicates a total project area of 13.59 acres. The stormwater narrative
indicates 114 acres available for industrial development. The site plan shows 8.454 acres for Lot
No. 4. What is the total area for this project? If the County has development plans for the
remaining portions of this 114 acre site, these plans should be provided, and a stormwater
application should be submitted prior to any further development. Please provide further
explanation with regard to acreage and development.
(3) The site plan does not delineate and show drainage basins. The stormwater narrative does not
adequately describe drainage basins. Show and describe all drainage basins, provide runoff
calculations for each basin, and show and describe all treatment measures for each drainage
basin.
(4) Regarding the information provided on the Underground Infiltration Trench Supplement Sheets:
a) The Supplement Sheet designates the soil type as Leaf but the attached explanation
states Lynchburg. These soils can vary significantly when considering infiltration rates
and their suitabilitylfor subsurface storage/disposal of stormwater runoff. There is no
information provided regarding actual field investigations and soil borings. On -site soil
borings and a detailed evaluation of soils and seasonal high water table conditions are
absolutely necessary to determine if the proposed stormwater control systems will work
for this site. If on -site soil borings show that predominately Leaf soils exist in the areas
proposed for infiltration, I have serious reservations about recommending that we permit
the proposed systems. The Lynchburg soils generally provide higher infiltration rates and
may be suitable for infiltration. In either case, both soil types typically experience a
seasonal high water table (SHWT) within 18-inches of the surface. The proposed
infiltration systems must maintain adequate separation from the SHWT in order to
function properly. The information provided does not adequately address these site
conditions.

b) The Stone Void Ratio used for this design was 42%; this is too high. For design
purposes the current Draft NC BMP document recommends a stone/void ratio of 30-35%
be used. Also, it is imperative that the plans and specifications stipulate that washed
stone be used rather than traditional aggregate base course materials.
c) Design volumes are shown but no calculations are provided. For each drainage basin
provide calculations for Storage Volume Required, Storage Volume Provided, Surface
Area Required, and Surface Area Provided.
d) No observation wells are shown. The use of porous concrete and subsurface infiltration
beneath the parking lot represents a somewhat unusual approach to stormwater control
in eastern North Carolina. This, coupled with marginal soil and water table conditions for
this site, is good reason to install observation wells for these systems. Please modify
plans and provide details.
e) Supplement sheet and plan details call for septic tank stone; this specification is not
adequate for the proposed systems. Please specify #57 Washed Stone or other suitable
type stone; list in specifications and revise plan details accordingly.
(f) I am not able to reconcile Storage/Overflow Elevations listed on the supplement sheets -
with the elevations shown on plan details. Please explain and/or revise plans.
g) Pages 2 & 3 of the supplement sheets list items a. through u. Each of these items should
be adequately addressed in the overall design of the stormwater controls. They should
be clearly shown on the plans and details, or otherwise stated in the stormwater
narrative. Please address each item (a through u); revise plans, details and stormwater
narrative as needed. If for some reason the design does not, or cannot, meet all the
requirements listed, a reasonable alternative or explanation, must be provided.
h) The operation and maintenance agreement listed on pages 3 & 4 of the supplement
sheet has not been revised/amended to adequately address operation and maintenance
requirements for these systems. Page 4 requires the notarized signature of the
responsible party; this page was omitted from the application (see add info # 6).
(5) The enclosed computations used an averaged infiltration rate from two different soil types. The
resulting infiltration rate selected was 0.44 inches/hour. The conservative and preferred
approach is to specify the most restrictive soil type and then use the corresponding infiltration rate
to design the system components. For infiltration systems the NC BMP Manual calls for a
minimum infiltration rate of 0.52 inches/hour. The Division of Water Quality recommends that an
alternative stormwater treatment design be chosen when site conditions do not meet the
"minimum infiltration rate". Please provide onsite observations of soils and infiltration rates and
explain how the proposed system is designed to overcome any site restraints that are evident.

(6) The enclosed Operation and Maintenance Agreement is not adequate. The O&M Agreement
should be revised to include (at a minimum) the following:
a) Name of Facility, Name of Responsible Party, Statement that reads, IANe do
hereby agree to operate and maintain this facility according to the following:
b) Next, list the components of the system, reasonable inspection frequencies,
stipulate how to recognize that the system is working properly, how to recognize
that the system needs maintenance, and specify what the maintenance activities
should entail.
c) Address how to matte needed repairs and proper disposal measures.
d) The 0&M Agreement should be signed by the responsible party and properly
notarized.
(7) The subsurface drains (outlet pipes) from each of the stone storage areas should be located as
far from the inlets as possible. In addition, the elevation of each outlet pipe should be positioned
to maximize the use of the entire storage area before discharging to the adjacent ditches. Please
review location and elevations of all outlet pipes; modify and revise plans as needed.
recommend that you refer to the Draft Revised NC BMP document found on our web page.
Section 3.11 provides new and detailed information about the design, construction and maintenance of
Permeable Pavements.
The above requested information must be received in this office prior to November 14, 2005 or
your application will be returned as incomplete. The return of this project will necessitate resubmittal of all
required items including the application fee. If you need additional time to submit the requiredinformation,
please mail or fax your request for time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to

Good Morning Sam, hope you are doing well.
Sam, I had to return the stormwater application for the Industry Ready Bldg to Paul
Spruill by letter dated August 24, 2005(copy to your office). In order to cut down on
long process times and keep our database somewhat current, we must officially return
projects; rather .than hold onto them indefinitely. I did receive your additional
information package regarding this project on September 1, 2005. The county will
have to resubmit -the project; new application, fee, plans & specs, in order to get a
permit. After you speak with Paul and when the county is ready to obtain a permit for
this site, I will be happy to work with you on this. Let me know if you have
questions.

DWQ-WARD
Thank you for..the,continued corresporidence regardinggthc`County's stormwater.applicaftonfor
Stormwater Project SW7041209 or the Beaufort County Industry... Ready Building. You and your
staff have been very helpful in assisting the County and its consultants with answering the
necessary questions to comply with the State's stormwater control expectations in coastal
counties.
I would like to.offer my sincere apologies .for:ourAisregard 6f the statutory. process as -evidenced
by the substantial construction that occurred at the project site prior to notification of stormwater
application, approval. As you and I discussed by phone, the County erred in beginning
constructing impervious surface areas and designed stormwater treatment systems at a point in
time when our application had been submitted but not approved.
I have carefully considered the County's mistAcs in.this process and'have studied thc.actions of
all involved. Please accept my assurance that the County did not intentionally take action in
violation of the State's requirements and with your permission we would look forward to partially
correcting our mistakes by providing the following assistance to NC DENR:
1) . Our consultants and contractors will cooperate with all necessary and agreed upon
changes to the stormwater infrastructure that is currently in place;
2) The County-will'.host a meeting of:alhCounty.6hd:Municipal Building Inspectors to
discuss these regulatory requirements and the need for local governments to withhold the
issuance of building permits to future projects until the proper stormwater permit is
approved by your office;
3) The County and the City will work together to include on the Cox Cable City Channel
information that informs area citizens about the process for stormwater permit application
and approval in tlie_State's coastal -counties;
4) I will speak to the Association of Beaufort County Realtors and the practicing Beaufort
County Engineers and Surveyors regarding the stormwater approval process in your
office and the stormwater approval process required as a result of the Tar-Pajn Rule.

Dear Mr. Spruill:
Alan W. Klimek, P.E. Director
Division of Water Quality
This office received a stormwater application for the subject project on December 13, 2004.
On January 19, 2005, Mr. Bill Moore of this office met with your engineer, Mr. Sam Jarvis, to discuss
the proposed project. A list of modifications needed to make the application complete was provided
to Mr. Jarvis at their meeting. Because the additional information was never received, a letter dated
August 24, 2005 returned the application.
The application was resubmitted on October 3, 2005. On October 11, 2005, Mr. Bill Moore of
this office inspected the Industry Ready Building site located adjacent to SR1456, and near the
intersection with Cherry Run Road near Washington, NC. Mr. Moore observed that the building and
parking lots were at an advanced stage of construction. Based on site observations and information
from the site plans, it is estimated that approximately 2.6 acres of impervious area is currently in
place. In addition, the proposed stormwater treatment systems have been constructed, including the
subsurface stone beds, the pervious concrete sections and the under drain pipes.
Be advised that the construction of the impervious areas and stormwater treatment systems
without a valid permit is a violation of NCGS 143-215.1 and 15A NCAC 2H.1003, and may subject
you to appropriate enforcement actions in accordance with NCGS 143-215.6. Civil penalties of up to
$10,000 per day per violation may be assessed for failure to secure a permit required by NCGS 143-
215.1.

Alan W. Klimek, P.E. Director
Division of Water Quality
This office received a Coastal Stormwater permit application and plans for the subject project on
October 3, 2005. A preliminary review of your project indicates that before a State Stormwater permit can
be issued the following additional information is needed.
-. ? The stormwater application form SWU-101, dated January 1998 is outdated; the current
stormwater application form is SMU-101, Version 3,99. This version can be found on our Division
web page, or we have hard copies available at this office. Please use current application forms in
the future. A
(2) Page 2 of the application indicates a total project a of 13.59 The stormwater narrative
.l indicates 114 acres, available for industrial developmen . e site plan shows 8.454 acres for Lot
No. 4. What is the total area for this project? If the County has development plans for the
remaining portions of this 114 acre site, these plans should be provided and a stormwater
application should be submitted prior to any further development. Please provide further
explanation with regard to acreage and development.
(3) The site plan does not delineate and show drainage basins. The stormwater narrative does not
adequately describe drainage basins. Show and describe all drainage basins, provide runoff
calculations for each basin, and show and describe all treatment measures for each drainage
basin.
(4) Regarding the information provided on the Underground Infiltration Trench Supplement Sheets:
a) The Supplement Sheet designates the soil type as Leaf but the attached explanation
states Lynchburg. These soils can vary significantly when considering infiltration rates
and their suitability for subsurface storage/disposal of stormwater runoff. There is no
information provided regarding actual field investigations and soil borings. On -site soil
borings and a detailed evaluation of soils and seasonal high water table conditions are
absolutely necessary to determine if the proposed stormwater control systems will work
for this site. If on -site soil borings show that predominately Leaf soils exist in the areas
proposed for infiltration, 1 have serious reservations about recommending that we permit
the proposed systems. The Lynchburg soils generally provide higher infiltration rates and
may be suitable for infiltration. In either case, both soil types typically experience a
seasonal high water table (SHWT) within 18-inches of the surface. The proposed
infiltration systems must maintain adequate separation from the SHWT in order to
function properly. The information provided does not adequately address these site
conditions.

The Stone Void Ratio used for this design was 42%; this is too high. For design
purposes the current Draft NC BMP document recommends a stone/void ratio of 30-35%
be used. Also, it is imperative that the plans and specifications stipulate that washed
stone be used rather than traditional aggregate base course materials.
Design volumes are shown but no calculations are provided. For each drainage basin
provide calculations for Storage Volume Required, Storage Volume Provided, Surface
Area Required, and Surface Area Provided.
No observation wells are shown. The use of porous concrete and subsurface infiltration
beneath the parking lot represents a somewhat unusual approach to stormwater control
in eastern North Carolina. This, coupled with marginal soil and water table conditions for
this site, is good reason to install observation wells for these systems. Please modify
plans and provide details.
Supplement sheet and plan details call for septic tank stone; this specification is not
adequate for the proposed systems. Please specify #57 Washed Stone or other suitable
type stone; list in specifications and revise plan details accordingly.
not able to reconcile Storage/Overflow Elevations listed on the supplement sheets
with the elevations shown on plan details. Please explain and/or revise plans.
g) Pages 2 & 3 of the supplement sheets list items a. through u. Each of these items should
be adequately addressed in the overall design of the stormwater controls. They should
be clearly shown on the plans and details, or otherwise stated in the stormwater
narrative. Please address each item (a through u); revise plans, details and stormwater
narrative as needed. If for some reason the design does not, or cannot, meet all the
requirements listed, a reasonable alternative or explanation must be provided.
The operation and maintenance agreement listed on pages 3 & 4 of the supplement
sheet has not been revised/amended to adequately address operation and maintenance
r' requirements for these systems. Page 4 requires the notarized signature of the
responsible party; this page was omitted from the application (see add info # 6).
J(5) The enclosed computations used an averaged infiltration rate from two different soil types. The
resulting infiltration rate selected was 0.44 inches/hour. The conservative and preferred
approach is to specify the most restrictive soil type and then use the corresponding infiltration rate
to design the system components. For infiltration systems the NC BMP Manual calls for a
minimum infiltration rate of 0.52 inches/hour. The Division of Water Quality recommends that an
alternative stormwater treatment design be chosen when site conditions do not meet the
"minimum infiltration rate". Please provide onsite observations of soils and infiltration rates and
explain how the proposed system is designed to overcome any site restraints that are evident,

J.,
County of Beaufort

The enclosed Operation and Maintenance Agreement is not adequate. The O&M Agreement
should be revised to include (at a minimum) the following:
a) Name of Facility, Name of Responsible Party, Statement that reads, IIWe do
hereby agree to operate and maintain this facility according to the following:
b) Next, list the components of the system, reasonable inspection frequencies,
stipulate how to recognize that the system is working properly, how to recognize
that the system needs maintenance, and specify what the maintenance activities
should entail.
c) Address how to make needed repairs and proper disposal measures.
d) The 0&M Agreement should be signed by the responsible party and properly
notarized.
(7) The subsurface drains (outlet pipes) from each of the stone storage areas should be located as
far from the inlets as possible. In addition, the elevation of each outlet pipe should be positioned
to maximize the use of the entire storage area before discharging to the adjacent ditches. Please
review location and elevations of all outlet pipes; modify and revise plans as needed.
recommend that you refer to the Draft Revised NC BMP document found on our web page.
Section 3.11 provides new and detailed information about the design, construction and maintenance of
Permeable Pavements.
The above requested information must be received in this office prior to November 14, 2005 or
your application will be returned as incomplete. The return of this project will necessitate resubmittal of all
required items including the application fee. if you need additional time to submit the required information,
please mail or fax your. request for time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to
any development activity. Construction without a permit is a violation of 15A NCAC 2H.1000 and North
Carolina General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.

[e-mail]
Dear Mr. Benton,
This is simply a follow-up to our phone conversation on Friday_ The handwritten note I
received from Sam Jarvis apparently was written under some degree of stress and was
highly critical of the local DEHNR procedures relating to stormwater permits. Although
it was a difficult note to read, I gathered that he planned on contacting you to complain
about these procedures and I fear that his complaints might be misunderstood by you or
others to whom they are addressed. Since he addressed you in his letter, I presume that he
perhaps has or might call you in the future. I want you to know that we had retained an
architect, Mr. Bill Gwinn, who in turn retained Mr. Jarvis to do the engineering portion of
the site development and the permitting work. Sam has a brilliant mind and has done
some brilliant work for us in the past, but he seems to have had some problem completing
the application on this and I fear he may be trying to cover his tracks. If he does so, .1
would like you to totally understand that we have had no problems with the local office
whatsoever and that Al Hodge, in particular, has just been the topic of a letter from my
organization to Secretary Ross commending him for the wonderful job he recently did on
the ethanol public meeting and permitting process.'
I know Sam has had some personal problems, including health problems, recently, but I
take full responsibility for not monitoring his performance through the architect better
and I would strongly encourage you to ignore any complaints related to the Quick Start
Building in Beaufort County forwarded to you by Mr. Jarvis if, in fact, he has done so.
Please know that we are highly appreciative of the efforts of the local Washington office
and have always been very impressed with the tremendous performance under very trying
circumstances of your staff here.
Very Truly Yours,
y

Subject: Percent aggregate voids for a stormwater BMP
Bill,
See attached several references I found on-line, and in the NC DOT
Standard Specifications book.
a) The California Stormwater BMP Handbook suggests trench rock that is
1.5" to 2.5" will normally have 35% void space.
b) The Georgia Stormwater Management Manual suggests that washed,
bank -run gravel 1.5" to 2.5" will have a void space of about 40%.
c) The Fairfax County, Virginia stormwater manual suggests percolation
trench design should be with VDOT #57 stone, and will have 400/6
voids.
d) I've also included two pages from the NCDOT Specs book that shows
that #5 coarse aggregate is 100% smaller than the 1-1/2" sieve Size.
I think I can argue either way in this situation. Arguing in favor of the
engineer's design: Linda has set a precedent of allowing around 4011/o voids
on #57, and she reports that 40% is the standard voids fraction for #57;
42% is not that different from the previously approved 40%, and as you can
see from the NC DOT spec sheet, #5 is -not that different from the previously
approved #57_ In fact, #5 has a slightly lesser amount of the smaller
fractions, which should, if anything, indicate a greater void space in #5
compared to #57. And, note that Fairfax County, Virginia suggests using

12/06/2005 17:01 9157335612 PAGE 02
#57, with a 4011/o voids fraction. So, on these bases, #57 at 42% should be
ok if supported by vendor technical testing data,
Arguing against the engineer's design: The supplier's spec Sheet shows
4213/b, and you used 42% in your design? Where, is your factor of safety?
What if the supplier provided only sort -of washed aggregate? Do you know
what kind of variability there might be in your supplier's product? .What if,
the compactive effort provided by the installing contractor was in excess of
that necessary? Were there compaction tests performed on the installation?
what were the compaction specs? How does the compactive effort affect
void fraction? Were you on site on the day of the aggregate placement, and
were you in effective control of the job site and the compaction? Do your
installation specs instruct the contractor not to use hydraulic compaction
methods? Do your installation specs instruct the contractor to prevent the
introduction of excess fines into the rock fill? The use of a factor of safety is,
in part, intended to address the likelihood that the design engineer. is
normally not in effective control of the construction effort, and that' the
integrity of his design is protected against such negative influences as
material variability and minor installation. mistakes by the factor of 'safety. If
he has included a factor of safety in some other step, such as in the
calculation of the design flow, then ok,. if his design does not have+ any
evidence of a factor of safety at all...
Note that two other stormwater regulatory agencies accept 3.5% to! 40% for
much bigger stone (California and Georgia suggest 1'/221/2" stone which
is bigger than #5, which has a max sieve size of only 11/2".) ,The point
being, that these two states use bigger rock, with presumably bigger void
space, but yet they don't reference a void fraction of 42%, but rater
reference 35% - 40%.
My sense is that in your present circumstances, the first argument Should
prevail. It encourages consistency, roughly, with Linda's precedent, It
avoids making a problem where there doesn't have to be one, now: I think.
between now and the next similar permit application we should hustle
around to try to get a firm basis for accepting or rejecting the design
specifics contained in this application, or the next application. My only
concern is that if we ok this submittal now, will this engineer think that the
door is open for him to non -engineer the next one, too? Will he just come
back to us saying, "You approved it last time, why not now? 'It's unfair that
DWQ is so grossly inconsistent, without technical basis_"
Maybe we can approve it this time and require frequent submittal of
monitoring data so that we can assess its effectiveness.

TC-10 Infiltration iTrench
■ As an underground $MP, trenches are unobtrusive and bave little impact of site aesthetics.
Limitations
■ Have it high failure rate if soil and subsurface conditions are not suitable.
■ May not be appropriate for industnal sites or locations where spills may occur_ '
■ The maximum contributing area tr) an individual infiltration practice should generally',be
less than g ages.
■ Infiltration basins require a minimum soil. iufiltration rate of o.S inches/hour, °not
appropriate at sites with Hydrologic Soil Types C and D.
■ If infiltration rates exceed 2.4 inches/hour, then the runoff Should be fully treated prior to
infiltration to protect groundwater quality.
■ Not suitable on fill sites or steep slopes.
■ Risk of groundwater contamiriation in very coarse soils_
■ Upstream drainage area must be completely stabilized before construction_
■ Difficult to restore (auctioning of infiltration trenches once clogged_
Design and Sizing Guidelines
■ Provide pretreatment for infiltration trenches in order to reduce the sedimentloacL
Pretreatment refers to design featiues that provide settling of large particles before runoff
reaches a management practice, easing the long-term maintenance burden. Pretreatment is
important for all structural stormwater management practices, but it is particularly
important for infiltration practices. To ensure that pretreatment mechanisms are effective,
designers should incorporate practices such as grassed swales, vegetated filter strips,
detention, or a pie pool in series.
s Specify locally available tt-mich rock that is 1.5 to 2.6 inches in diameter.
■ Determine the trench volume by assuming the WQV will fill the void space based on the
computedpormity of the rock matrix (normally about 35%).
■ Determine the bottom surface area needed to drain the fire within 7a hr by, dividing the
WQV by the infiltration rate_ n j

► The stone aggregate used in the trench should be washed, rank -run gravel, 1.5 to 2.5 inches
in diameter with a void space of about 40% (GADOT No.3 Stone). Aggregate contaminated
with soil shall not be used. A porosity value (void space/ictal volume) of 0.32 should be used
f
r
► A 6-inch layer of clean, washed sand is placed on the bottom of the trench to encourage
drainage and prevent compaction of the native soil while the steno aggregate is added.
► The infiltration trench is lined on the sides and top by an appropriate geotextile filter fabric
that prevents soil piping but has greater permeability than the parent soil, The top layer of
filter fabrlo Is located 2 to 6 inches from the top of the trench and serves to prevent sediment
from passing into the stone aggregate. Since this top layer serves as a sedimentbarrier, it
will need to be replaced more frequently and must be readily separated from the side
sections.
/ The top surface of the infiltration trench above the filter fabric is typically covered with pee
gravel. The pea gravel layer improves sediment filtering and maximizes the pollutant removal
in the top of the trench. In addition, it can easily be removed and replaced should the device
begin to clog_ Alternatively, the trench can be covered with permeabte topsoil and planted
with grass in a landscaped area.
No An observation wall must be installed in every infiltration trench and should consist of a
perforated PVC pipe, 4 to 6 inches in diameter, extending to the Wttom of the trench (see
Appendix B for a schematic of an ah6orvation well). The observation well will show the rate
of dewatering after a storm, as well as provide a means of determining sediment levels at the
bottom and when the filter fabric at the top is clogged and maintenance is needed. It should
be installed along the centerline of the structure, flush with the ground elevation of the trench.
A visible floating marker should be provided to indicate the water level. The top of the well
should be capped and locked to discourage vandalism end tampering.
The trench excavation should be limi od to the width and depth specified in the design.
Excavated material should be placed away from the open trench so as not to jeopardize the
stability of the trench sidewalls, The bottom of the excavated trench shall not be loaded in a
way that 0aUses soil compaction, and should be scarified prior to placement of sand. The
sides of the trench shall be trimmed of all large roots, The sidewalls shall be uniform with no
voids and scarified prior to backfilling. All infiltration trench facilities should be pratactod
during site construction and should bQ Constructed after upstreaan areas have been
stabilized-
D. PRLTREATMENT / INLETS
F Pretreatment facilities must always he used in conjunction with an infiltration trench to
prevent clogging and failure,
► For a trench recoiVing sheet flow from an adjacent drainage area, the pretreatment system
should consist of a vegetated filter strip with a minimum 25-foot length. A vegetated) buffer
strip around the entire trench is required if the facility is receiving runoff from both directions,
If the infiltration rate for the underlying soils is greater than 2 inches per hour, 50% of the
WO, should be pretreated by another method prior to reaching the infiltration trench.
► For an off-line configuration, pretreatment should consist of a sediment forebay, vault, plunge
pool, or similar sedimentation chamber (with energy dissipaters) sized to 25% of the water
quality volume (WQ„). Exit velocities from the pretreatment chamber must be nonarosive for
the 2-year design storm.

Washington, NC 27889
Subject: Stormwater Permit No. SW7051002
Industry Ready Building, Lot 4
High Density Stormwater Project
Beaufort County
Dear Mr. Spruill:
The Washington Regional Office received your completed
Stormwater Application for the subject project on December 14,
2005. 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. We are
forwarding Permit No. SW7051002 dated. December +,4Y, 2005 to
Beaufort County. Z.o
This permit shall be effective from the date of issuance
until December 20, 2010 and shall be subject to the conditions and
limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements in this permit.
Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in
future compliance problems.
If any parts, requirements, or limitations contained in this
permit are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty (30) days
following receipt of this permit. This request must be in the.
form of a written petition, conforming to Chapter 150B, of the
North Carolina General Statutes, and filed with the Office of
Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27511-
7447. Unless such demands are made .this permit shall be final and
binding.

► An appropriate modular porous paver should be selected for the intended application. A
minimum of 40% of the surface area should consist of open void space. If it is a load bearing
surface, then the pavers should be able to support the maximum load.
► The porous paver infill is selected based upon the intended application and required
infiltration rate_ Masonry sand (such as ASTM C-33 concrete sand or GADOT Fine
Aggregate Size No. 10) has a high infiltration rate (8 in/hr) and should be used in applications
where no vegetation is desired. A sandy loam soil has a substantially lower infiltration rate
(1 in/hr), but will provide for growth of a grass ground cover.
► A 1-inch top course (filter layer) of sand (ASTM C-33 concrete sand or GADOT Fine
Aggregate Size No. 10) underlain by filter fabric is placed under the porous pavers and above
the gravel base course.
► The gravel base course should be designed to store at a minimum the water quality volume
(WQ„). The stone aggregate used should be washed, bank -run gravel, 1.5 to 2.5 inches in
diameter with a void space of about 40% (GADOT No.3 Stone). Aggregate contaminated
with soil shall not be used. A --porosity value:(void:space/total:volume)-of 0.32.should. be:use6
tin -calculations.
► The gravel base course must have a minimum depth of 9 inches. The following equation can
be used to determine if the depth of the storage layer (gravel base course) needs to be
greater than the minimum depth:
d=V/A'n
Where:
d = Gravel Layer Depth (feet)
V = Water Quality Volume —or— Total Volume to be Infiltrated
A = Surface Area (square feet)
n = Porosity (use n=0.32)
► The surface of the subgrade should be lined with filter fabric or an 8-inch layer of sand
(ASTM C-33 concrete sand or GADOT Fine Aggregate Size No. 10) and be completely flat to
promote infiltration across the entire surface.
► Porous paver system designs must use some method to convey larger storm event flows to
the conveyance system. One option is to use storm drain inlets set slightly above the
elevation of the pavement. This would allow for some ponding above the surface, but would
accept bypass flows that are too large to be infiltrated by the porous paver system, or if the
surface clogs.
► For the purpose of sizing downstream conveyance and structural control system, porous
paver surface areas can be assumed to be 35% impervious. In addition, credit can taken for
the runoff volume infiltrated from other impervious areas using the methodology in
Section 3.1.

Subject: Stormwater Review SW7051002
Industry Ready Building, Lot No. 4
Beaufort County
Alan W. Klimek, P.C. Director
Division of Water Quality
This office received a Coastal Stormwater permit application and plans for the subject project on
October 3, 2005. A preliminary review of your project indicates that before a State Stormwater permit can
X(l)
issued the following additional information is needed.
(1) The stormwater application form SWU-101, dated January 1998 is outdated; the current
stormwater application form is SMU-101, Version 3.99. This version can be found on our Division
web page, or we have hard copies available at this office. Please use current application forms in
{2}
the future.
Page 2 of the application indicates a total project area of 13.59 acres. The stormwater narrative
indicates 114 acres available for industrial development. The site plan shows 8.454 acres for Lot*—B4S'�
No. 4. What is the total area for this project? If the County has development plans for the qC.
remaining portions of this 114 acre site, these plans should be provided and a stormwater
application should be submitted prior to any further development. Please provide further
explanation with regard to acreage and development
The site plan does not delineate and show drainage basins. The stormwater narrative does not
adequately describe drainage basins. Show and describe all drainage basins, provide runoff
calculations for each basin, and show and describe all treatment measures for each drainage
basin.
Regarding the information provided on the Underground Infiltration Trench Supplement Sheets:
a) The Supplement Sheet designates the soil type as Leaf but the attached explanation
states Lynchburg. These soils can vary significantly when considering infiltration rates
and their suitability for subsurface storage/disposal of stormwater runoff. There is no
information provided regarding actual field investigations and soil borings, On -site soil
borings and a detailed evaluation of soils and seasonal high water table conditions are
absolutely necessary.to determine if the proposed stormwater control systems will work
for this site. If on -site soil borings show that predominately Leaf soils exist in the areas
proposed for infiltration. I have serious reservations about recommending that we permit
the proposed systems. The Lynchburg soils generally provide higher infiltration rates and
may be suitable for infiltration. In either case, both soil types typically experience a
seasonal high water table (SHWT) within 18-inches of the surface. The proposed
infiltration systems must maintain adequate separation from the SHWT in order to
function properly. The information provided does not adequately address these site
conditions.

The Stone Void Ratio used for this design was 42%; this is too high. For design
purposes the current Draft NC BMP document recommends a stone/void ratio of 30-35%
be used. Also, it is imperative that the plans and specifications stipulate that washed
stone be used rather than traditional aggregate base course materials.
Design volumes are shown but no calculations are provided. For each drainage basin
provide calculations for Storage Volume Required, Storage Volume Provided, Surface
Area Required, and Surface rea rov0 e .
No observation wells are shown. he use of porous concrete and subsurface infiltration
beneath the parking lot represents a somewhat unusual approach to stormwater control
in eastern North Carolina. This, coupled with marginal soil and water table conditions for
this site, is good reason to install observation wells for these systems. Please modify
plans and provide details.
Supplement sheet and plan details call for septic tank stone; this specification is not
adequate for the proposed systems. Please specify #57 Washed Stone or other suitable
type stone; list in specifications and revise plan details accordingly.
I am not able to reconcile Storage/Overflow Elevations listed on the supplement sheets
with the elevations shown on plan details. Please explain and/or revise plans.
Pages 2 & 3 of the supplement sheets list items a. through u. Each of these items should
be adequately addressed in the overall design of the stormwater controls. They should
be clearly shown on the plans and details, or otherwise stated in the stormwater
narrative. Please address each item (a through u); revise plans, details and stormwater
narrative as needed. If for some reason the design does not, or cannot, meet all the
requirements listed, a reasonable alternative or explanation must be provided.
h) The operation and maintenance agreement listed on pages 3 & 4 of the supplement
sheet has not been revised/amended to adequately address operation and maintenance
requirements for these systems. Page 4 requires the notarized signature of the
responsible party; this page was omitted from the application (see add info # 6).
The enclosed computations used an averaged infiltration rate from two different soil types. The
resulting infiltration rate selected was 0.44 inches/hour. -The conservative and preferred
approach is to specify the most restrictive soil type and then use the corresponding infiltration rate
to design the system components. For infiltration systems the NC BMP Manual calls for a
minimum infiltration rate of 0.52 inches/hour. The Division of Water Quality recommends that an
alternative stormwater treatment design be chosen when site conditions do not me6t the
"minimum infiltration rate". Please provide onsite observations of soils and infiltration rates and
explain how the proposed system is designed to overcome any site restraints that are evident.

(6) The enclosed Operation and Maintenance Agreement is not adequate. The O&M Agreement
should be revised to include (at a minimum) the following:
a)
Name of Facility, Name of Responsible Party, Statement that reads, IIWe do
hereby agree to operate and maintain this facility according to the following:
Next, list the components of the system, reasonable inspection frequencies,
stipulate how to recognize that the system is working properly, how to recognize .�
that the system needs maintenance, and specify what the maintenance activities
should entail.
Address how to make needed repairs and proper disposal measures.
The 0&M Agreement should be signed by the responsible party and properly
notarized.
(7) The subsurface drains (outlet pipes) from each of the stone storage areas should be located as
far from the inlets as possible. In addition, the elevation of each outlet pipe should be positioned
to maximize the use of the entire storage area before discharging to the adjacent ditches. Please
review location and elevations of all outlet pipes; modify and revise plans as needed.
I recommend that you refer to the Draft Revised NC BMP document found on our web page.
Section 3.11 provides new and detailed information about the design, construction and maintenance of
Permeable Pavements.
The above requested information must be received in this office prior to November 14, 2005 or
your application will be returned as incomplete. The return of this project will necessitate resubmittal of all
required items including the application fee. If you need additional time to submit the required information,
please mail or fax your request for time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to
any development activity. Construction without a permit is a violation of 15A NCAC 21-1.1000 and North
Carolina General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.
If you have questions, please feel free to contact me at [phone].

Good Morning Sam, hope you are doing well.
Sam, I had to return the stormwater application for the Industry Ready Bldg to Paul
Spruill by letter dated August 24, 2005(copy to your office). In order to cut down on
long process times and keep our database somewhat current, we must officially return
projects; rather than hold onto them indefinitely. I did receive your additional
information package regarding this project on September 1, 2005. The county will
have to resubmit the project; new application, fee, plans & specs, in order to get a
permit. After you speak with Paul and when the county is ready to obtain a permit for
this site, I will be happy to work with you on this. Let me know if you have

NARRATIVE DWQ-WARD
The project is owned by Beaufort County and is planned to be an industry ready building
of 40,000 square feet floor area. The site has been provided with 13.59 acres of land.
The ultimate size of future buildings, parking lots, loading areas, etc. are a matter of such
speculation, it serves no purpose to guess. There are 114 acres available for industrial
development and the final configuration of lot size, shape, etc. will be determined as
needed.
The proposed site will have 9.7% impervious area in Phase I but expansion will increase
that amount to over 30% at some future time. During the design process, consideration
was given to two major items. (A) That ultimately the site would most likely be high
density and that it would be an environmental injustice to not plan for aggressive
stormwater management. (B) That Phase H rules concerning nitrogen and phosphate
reduction would come into effect in October 2004.
The Beaufort County Economic Development Board and the commissioners accepted and
funded the cost of providing the treatment measures and to set the stage for meeting all
discharge requirements.
The system is comprised of porous concrete acting as catch basins. The permeability of
the concrete is 0.5 GFM / S.F. and we use a safety factor of between six and ten; i.e.:
should the catchment area require 20 S.F. of porous concrete, we design between 120 and
200 S.F. of area. r 7
The storage stone is of septic tank variety having a void space of 42% to 48%. We
commonly use the 42% volume and allow for some surplus storage. The stone is
completely wrapped with a non -woven geo-technical fabric to prevent sediment in the
stone. The porous concrete contains the TSS and yard debris. Although porous concrete
installations have yet to fail due to blockage, we do recommend as part of a prudent
O&M plan that the concrete be Rressure washed and vacuumed no greater than five-year
intervals. OVA c.-/% v K +
There will be stone trenches provided to be used as conduits. Additionally, draw down
manifolds are being provided that will insure the storage areas will be drained in a 36 to
72 hour period. We do not anticipate the draw down structure will have to work very
often because the soil permeability is much greater that the draw down rate.

There will be no discharge from any impervious area on the site that does not pass a)
through a detention infiltration treatment and from there b) through a BNIgQf grassed
waterways.
The system eliminates or reduces substantially below the regulatory threshold the
nitrogen and phosphate discharges. The storage areas beyond the parking lot also acts as
an overflow basin, as well as a dry detention landscape area. Tle maintenance for these
syALqUj%.ja nil. The main concern is to have a responsible review of tporouse concrete
and remove trash and sediment to avoid a buildup.
The system has been designed by Sam Jarvis, has a provisional patent and has been
installed in various design forms in:
1. New Bern, North Carolina
2. Greenville, North Carolina
3. Goldsboro, North Carolina
4. Anderson, South Carolina
The Beaufort County Economic Development Board plans to have a comprehensive
stormwater management plan developed for the site, which will specify the discharge
treatment storage, etc. of each potential site in the industrial park.
