On behalf of our client, Jenco Concrete Associates, Inc., please find the revised
submittal package in response to your 2°d review comments for the above referenced
project. Your review comments have been based on our phone conversation on June
24`h, 2008. Our responses to your comments are as follows:
1. The Post Development Drainage rilap shows Dot-400 with a calculated pervious
area of 0.34 acre. This .seems like a lot of pervious area for this drainaf;le area.
The vet detention pond should be counted as impervious area.
Response: Drainage Area DA-400 is now calculated as having 0.16 acres of
pervious area. Previously, the wet detention basin was not counted toward the
impervious area, but has been changed to be included as impervious. The area
within the 263.50 contour of the wet detention basin has been added as
impervious area for the drainage area, which relates to the 10-year storm water
surface area. This should be more conservative then only counting the
permanent pool surface area. The post -development quantity calculations and
wet detention sizing calculations have been updated. The wet detention basin
size was increased as necessary.
2. On the Gracling, Drainage. and Utility Plan Sheet (C-3) the drainage into the
settlement chamber is not clearly defined Please change the gracling as
necessary to clearly show the wastewater and stornnvater flowing into the
settlement chrnnber.
Response: A spot grade of 266.00' has been located in front of the settlement
chamber on the Grading, Drainage, and Utility Plan Sheet (C-3). This should
insure that the wastewater and stormwater will flow into the settlement chamber
for treatment.

NPDES General Permit NCG140000 Resubmittal
Our Ref: 012858000
On behalf of our client. Jenco Concrete Associates. Inc., please find the revised
submittal package in response to your 1st review comments for the above referenced
project. Our responses to your comments are as follows:
Aggregate Pile Irrigation: The application indicated discharges from wetting of
raw material stockpiles would occur at this site (Question 14) and referred to
"runoff generated from stockpile areas" cis "stormwater. " Any drainage from
areas where ratio material stockpiles are wetted is considered wastewater, and
the application must demonstrate treatment sufficient to ineet effluent limits in
NCG14000. The narrative simply e_iplains that the storinwater wet detention
"basin will provide 85% TSS removal for aggregate stockpile areas... " This
.statement is not adequate to demonstrate the discharge from the area will meet
'.'effluent limits for TSS and settleable solids (SS). The 8.5% removal efficiency for
TSS in a wet detention basin is an assumed efficiency for storinivater based on
BMP design guidelines. Please (1) provide calculations (such as Stoke's Law) or
other information (e_g. data from a similar plant arrangement) to demonstrate
that this wastewater discharge from the ratio material stockpile area will ineet
effluent limits when treated and discharged from the basin, or (2) redesign the
configuration to capture and treat this water differently and revise the site plan
accordingly.
Response: The narrative has been updated and now refers to the runoff from the
stockpile area as wastewater. The Stoke's Law calculation for the wet detention
basin has been added to the "Water Quality and Process Wastewater Treatment"
section of the report. The provided Stoke's Law calculation was performed
during the initial design of the wet detention basin; however, it was not included
in the report. The calculation shows that during maximum operating conditions
all remaining particles greater than 12 micron in diameter will be removed in the
pond. All references referring to the 85% TSS removal rate have been removed
from the narrative, as they are irrelevant to the removal efficiency of the basin.

2. Please clarifi if the "truck wash down area" includes both mixing drum
washouts and vehicle and equipment cleaning,
Response: The truck wash down area does include both the mixing drum
washouts and vehicle and equipment cleaning areas. The narrative has been
modified to include this in the background information.
3. The Stoke's Latin calculation only addressed settling in the settlement chamber.
The calculations do not demonstrate that settling and retention trine in the wet
detention pond will meet TSS oncd SS effluent limits. This wastewater will
ultintately flow into the wet detention basin; however, the application does not
demonstrate that the wet detention basin will provide treatment to meet TSS and
SS limits other than a blanket statement that "the basin will provide 85% TSS
removal" (an assumed efficiency based on stormwater BMP design guidelines).
This is not a sufficient engineering -based demonstration for a wastewater
treatment facility. Please (1) expand the Stoke's Law calculations to address
particle settling in the wet detention basin (i.e. show that the discharge leaving
the wet detention basin will meet SS and TSS limits in the permit) or (2) redesign
the aggregate pit and settlement chamber to achieve limits prior to flow into the
detention basin.
Response: Concur. The Stoke's Law calculation for the wet detention basin has
been added to the "Water Quality and Process Wastewater Treatment" section of
the report. The provided Stoke's Law calculation was performed during the
initial design of the wet detention basin; however, it was not included in the
report. The calculation shows that during maximum operating conditions all
remaining particles greater than 12 micron in diameter will be removed in the
pond. All references referring to the 85% TSS removal rate have been removed
from the narrative, as they are irrelevant to the removal efficiency of the basin.
4. No particle size distribution for cement particles or other particle size
information was presented in the submittal. The basis of the design does not
appear to be the size of the particles expected to enter the treatment system, but
rather a back-calcidaterd diameter based on the volume of the chamber. If a
npical—nnediaii—particle diameter for cement particles is IS microns, settling
particles greater than 40 microns will likely not achieve SS and TSS
concentrations required by the permit. Please outline assumptio►ls about particle
size and be sure the overall design will meet effluent limits.
Response: Concur. The Stoke's Law calculations have been updated to include
both the settlement chamber design for settling particles of 40 microns, and the
wet detention pond design of settling 12 microns. The settlement chamber is
designed to remove larger particles from the wash down area at 40 microns. The
wet detention pond has been designed to remove up to 12 microns, and should
remove the cement particles at 15 microns.

❑ � ❑ Kimley-Horn
and Associates, Inc.
5. The volume of the settlement chamber is lower than the combined volume from a
10-Year, 24 hour- stornt event and the estimated 2000 gpd ma.virnwn production
water flow (2847 cf anticipated volunre of throughput + ntnoff versus a 2700 cf
volume in the chamber). The design appears to be for a storm less than the 10-
year event, unless the aggregate pit dintensions provide additional volume
(approximately 1000 cf). This is not clear in the calculations. The design
should be consistent with the narrative.
Response: The calculations provided show that the settlement chamber is sized
for the combined volume of the 10-year, 24-hour storm event and the estimated
2,000 gpd maximum production water flow. According to the routing
_information the 10-year, 24-hour storm event does produces a discharge of 2.426
cfs. However, the 2,000 gpd equals 267 ft'/day and provides a total storage
requirement of 2,693 cf. This is less than the 2,700 cf, which the wet detention
basin is sized to meet.
6. What amount of solids ►will be allowed to accumulate prior to cleaning? There
were no assumptions about solids depth in the design volume calculations, and
this depth will affect detention time.
Response: An additional foot of depth was added to the bottom of the settlement
chamber to accommodate for particle deposition. The additional depth adds
approximately 600 cf to the settlement chamber volume. This additional volume
will not be accounted for in the calculated volume for the settlement chamber, as
this volume will be allowed to fill with deposition and will not be used for
treatment. The facility will be required to remove the deposited particles from
the settlement chamber once the depositions meets the cleanout elevation marker.

• One (1) copy of the "Stormwater, Process Wastewater, & Erosion Control

Application Return (Return #1 178)
Wake County
Dear Mr. Lochren:
On March 17, 2008, the Division of Water Quality received your Notice of Intent (NOI)
requesting coverage and an Authorization to Construct (ATC) under general stormwater and
wastewater permit NCG140000. After preliminary review, the Stormwater Permitting Unit
(SPU) has determined the submitted materials are insufficient for us to continue processing this
application. The deficiencies are explained below to help you resubmit a complete application.
Aggregate Pile Irrigation: The application indicated discharges from wetting of raw
material stockpiles would occur at this site (Question 14.) and referred "runoff generated
from stockpile areas" as "stormwater.'" Any drainage from areas where raw material
stockpiles are wetted is considered wastewater, and the application must demonstrate
treatment sufficient to meet effluent limits in NCG140000. The narrative simply explains
that the [stormwater wet detention] "basin will provide 85% TSS removal for aggregate
stockpile areas...." This statement is not adequate to demonstrate the discharge from that
area will meet effluent limits for TSS and settleable solids (SS). The 85 percent removal
efficiency for TSS in a wet detention basin is an assumed efficiency for stormwater,
based on BMP design guidelines. Please (1) provide calculations (such as Stoke's Law)
or other information (e.g., data from a similar plant arrangement) to demonstrate that this

2. Design Calculations and Demonstration of Compliance with Effluent Limits
a. Please clarify if the "truck wash down area" includes both mixing drum washouts
and vehicle and equipment cleaning.
b. The Stoke's Law calculation only addresses settling in the settlement chamber.
The calculations do not demonstrate that settling and retention time in the wet
detention pond will meet TSS and SS effluent limits. This wastewater will
ultimately flow into the wet detention basin; however, the application does not
demonstrate that the wet detention basin will provide treatment to meet TSS and
SS limits other than a blanket statement that "the basin will provide 85% TSS
removal" (an assumed efficiency based on stormwater BMP design guidelines).
This is not a sufficient engineering -based demonstration for a wastewater
treatment facility. Please (1) expand the Stoke's Law calculations to address
particle settling in the wet detention basin (i.e., show that the discharge leaving
the wet detention basin will meet SS and TSS limits in the permit) or (2) redesign
the aggregate pit and settlement chamber to achieve limits prior to flow into the
detention basin.
c. No particle size distribution for cement particles or other particle size information
was presented in the submittal. The basis of the design does not appear to be the
size of the particles expected to enter the treatment system, but rather a back -
calculated diameter based on the volume of the chamber. If a typical median
particle diameter for cement particles is 15 microns, settling particles greater than
40 microns will likely not achieve SS and TSS concentrations required by the
permit. Please outline assumptions about particle size and be sure the overall
design will meet effluent limits.
d. The volume of the settlement chamber is lower than the combined volume from a
10-year, 24-hour storm event and the estimated 2000 gpd maximum production
water flow (2847 cu. ft. anticipated volume of throughput + runoff versus a 2700
cu. ft. volume in the chamber). The design appears to be for a storm less than the
10-year event, unless the aggregate pit dimensions provide additional volume
(approximately 1000 cu. ft.?). This is not clear in the calculations. The design
should be consistent with the narrative.
e. What amount of solids will be allowed to accumulate prior to cleaning? There
were no assumptions about solids depth in the design volume calculations, and
this depth will affect detention time.
The return of this application does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or permits required by the
Division of Land Resources, Coastal Area Management Act or any other federal or local
governmental permit or approval that may be required.

rev 11/21/08
6/24/2008. Phoned Ryan Lewis with Kimley-Horn and Associates (919.678.4148,
[e-mail]) to discuss submitted design plans and calculations.
Requested additional information, particularly with regard to Stoke's Law talcs for the final
discharge (must include settling in pond, which is part of treatment train).
10122: Spoke with Ryan Lewis about additional information calculations.
ATC Plans and Calculations Review
• Drainage area does not include stormwater pond surface area as impervious area
(will be important for wastewater treatment calculations because the pond receives
direct rainfall, and detention time won't account for that extra volume).
• What are assumptions for production water use and truck washdown? Does that
include runoff from that area or washout amount (or both)?
• Appears stockpile wetdown and some truck washout runoff could bypass settling
chamber and flow directly to the wet pond via concrete flumes; is that intentional?
• Calcs assert particles greater than 12 microns will be removed, but a significant
portion of cement particles (>46 percent) are typically smaller. Also, the calculation
is not carried out far enough to demonstrate compliance with TSS limit. [What are
the assumptions about mass in and out? How does end result comply with 30 mgll
limit?]
• Also, stormwater pond is part of wastewater treatment — need to either carry talcs
through pond with cement particle to demonstrate adequate treatment or meet
limits at end of settling chamber. Additionally, if pond receives aggregate pile
wetdown runoff, it is treating that wastewater (i.e., ATC will apply to the pond as
well).
• Fortrans unit to adjust pH before pond -- okay.
Additional Information Review (submitted 9119108)
• See 9119 response letter from consultant for summary of issues addressed.
• Assumptions clearly outlined in calculations. Ten-year design storm basis.
• Stoke's Law calculations expanded to include pond (which was also resized since
original submittal; amendments submitted to Wake County as per requirement.)
• Design is conservative in several aspects: (1) no settling attributed to pH adjustment
(but there will be some); (2)'Stoke's Law calculations estimated removal efficiency
based on a ratio of the settling velocity to the critical velocity (rather than assuming
a certain percentage of the particles are distributed above and below weir in the
water column) —this approach attempts to account for `suction' of some particles over
the weir even when they should settle below it); (3) settling chamber and retention
pond calculations allow for one foot of solids accumulation (volume not included in
calculations)
• Discussed orifice size and location in pond. Recommended turned down outlet —will
modify. (Should be especially mindful of potential clogging, given that this is a
concrete production facility.)
• Reviewer recommends approval.

Hi Judy,
I just wanted to check in on this one -- it's a proposed NCG140381. We're at the
30-day mark, so if the RRO is okay with this one, I think I'll move forward to issue
the CDC and ATC for this proposed plant in Knightdale. If you have any objections or
want us to hold longer, please try to let me know by Friday. Otherwise I'll plan to
get the package to Sarah for issuance by then.
Thanks so much,

I Hi Judy,
We've received an NOI for the proposed Jenco Concrete Plant in Knightdale for
coverage under NCG14, which includes an ATC request for the proposed wastewater
treatment systems. We've already been through a couple add. info. requests, and
I'm in the midst of reviewing the most recent one -- submitted last month. So far
it seems they've addressed our concerns, so I wanted to go ahead and request RRO
input.
This plant will discharge stormwater and wastewater (truck washout) to a UT to
Marks Creek, C-NSW waters (really a DOT ditch from what I can tell), through a
settling chamber arrangement and a wet detention pond. Although Wake County is
responsible for the post -construction review of the wet detention stormwater device
proposed, it has become wrapped into our NCG14 ATC review because the detention
pond will also treat wastewater discharge from truck washout and receive aggregate
pile runoff (both wastewaters under the NCG14 permit). The add info. I got last
month went through talcs for showing compliance with TSS, pH, and SS limits at the
outlet of that pond (by looking at settling in the washout settling pit chambers
and in the pond).
I'm attaching the NOI to this email and subsequent responses to our add info.
requests. I'm also mailing you a hard copy of the plans and excerpt from the talcs
(not all the talcs because it was a huge binder of stuff). I included mainly some
site maps and the overview of the proposal that I thought would be useful to you.
However, if you get it and need to see more, please let me know.
Incidentally, included was a confirmation signed by Bob Zarzecki in 2002 that a
drainage feature on site was an ephemeral stream not subject to Neuse Riparian
Buffer Rules. A copy of that correspondence will be in the envelope.
Does the Raleigh Regional Office have any concerns about issuing this facility a
COC/ATC for this general permit? If we don't receive any objections or requests
from RRO to hold until further notice, we will consider moving forward with the
COC/ATC in 30 days, as long as no other information is needed from their engineer.
If you have any questions, please let me know.
Thanks'.

From: Bethany Georgoulias<[e-mail]>

To: [e-mail]
Ryan,
Here is a link to the NIST study that examined the particle distribution of portland
cement:
http://www.fire.nist.qov/bfrlpubs/buiidC4/PDF/bC4O4O.pdf
The values I've seen used are in Table 2 under the 'PM + SM' section in the 'Mean'
column. Those values refer to the (cumulative) percent of particles (mass -based)
that are present at that micron size. For example, in Portland Cement, this method
estimated 47.2% of the mass is present as particles 12 microns or smaller. That's a
sizeable portion of the cement particles that could make it through the pond in this
design, so the design calculations should be carried out further (and assumptions
stated) to demonstrate there should be no more than 30 mg/1 TSS in the discharge
during a 10-yr storm event. If you foresee a problem meeting that, you may need to
re-examine what detention time will be needed to meet the 30 mg/1 limit.
Also, don't forget the NCG14 permit also imposes a Settleable Solids limit of 5
mi/1. SS is defined as the solids that will settle to the bottom of a cone shaped
container in a 60 minute period. You'll need to look at the settling velocity of the
particles that make it through and see if the amount that will settle to achieve 5
ml/1 concentration or less. .(It's most straightforward when the treatment system has
removed all the particle sizes that would have settled within an hour because you can
predict 0 ml/1).
If you have any questions while you're working on addressing these items or the
others that we discussed on the phone today, please feel free to give me a call.
