Revised 3/5/09
DPD Team Concrete - Greenville Ready -Mix Plant
Summary - . "
This facility submitted a Notice of Intent to be covered under General Permit NCG140000
(Ready -mixed Concrete), including an ATC for a pH adjustment system. The stormwater
discharge drains to an old mine pit pond and ultimately (?) to a tributary to Johnsons Mill
Run (Class WS-IV; NSW), in the Neuse River Basin. This facility is located in Pitt
County, handled by the Washington Regional Office.
Application review
a) The permit application has been signed and sufficiently completed. Yes, after
an initial return (Ret. No. 1197 on 10/29/08).
b) The SIC code accurately describes this facility's activities and is covered by this
general permit. Yes, SIC 3273 (Ready -mixed Concrete).
c) Does the facility propose a new or expanding wastewater discharge to ORW
waters (not allowed), or waters upstream of ORW (special limits may apply)?
No.
d) DEH or Shellfish Sanitation Approval Required? Yes, Water Supply water.
e) Regional Office DEH approval requested: 1112109 (H. Bailey, WaRO)
RO Approval received: 214109 (see memo).
f) Does this facility have other permits? No. However, local stormwater
control requirements by Greenville/Pitt County apply.
g) Hazardous Waste Activities? No.
li) DLR Mining Permit status: NIA (although pond is an old mine site).
i) Regional Office input requested: 12123108 (T. Edgerton, WaRO)
RO Approval received: 315109 (via phone).
j) Is an ATC/ATO Required (NCG02 or NCG14)? Yes. See Special Notes.
k) Erosion/Sedimentation Plan Applied for [NCG14 or NCG02 ATC only]?
N/A — already built.
1) Application/ATC approved? Yes
in) In Mecklenburg or Wake County (If so, copy final COC there)? No.
n) Special Notes: An ATC is required for Fortrans pH unit; however,
authorization to operate existing treatment systems (built before permit
approved) will also need to be included with COC. Multi -chambered
settling system treats truck rinse and drum washout water at the

eastern corner of the plant. Aggregate/stockpile wet -down and
associated run-off appears to bypass the truck rinse pit? (Application
indicates plant uses truck rinse water for wet -down...). How will that
be sampled? SDO-0011 only samples discharge from truck rinse system.
Engineer will need to supply information to demonstrate compliance
with limits at outlet of pond (because it will treat wastewater). See
review notes below.
Site visit on 2/4/09 - see attached photos.
Phone & E-mail logs
12/23/2008: E-mailed Jinn Frei re: questions.
See attached e-mail correspondence with consultant and WaRO.
Original Plan Submittal Review
• Fortrans pH control system proposed - ok. Demonstrates ability to control
pH within 6-9 limits.
• Calculations demonstrate sufficient volume and settling time to achieve 30
mg/l TSS in 10-year storm event.
• Settling talcs do not assume any amount of concrete input into the system
from external vehicle wash water (just drum washout). However, they also
assume a bulk density of Portland Cement (94 lb/cu. ft, accounts for voids
when dry) rather than the density of a cement particle (closer to 200 lb/cu.
ft)...so, safety factor built into talcs (particle is heavier and will settle faster).
• Wet -down of aggregate piles going to old pit pond at back of property.
Treatment? (See add. info. review. Even if using treated rinse pit water
instead, should meet any applicable limits.)
• Where does that ultimately discharge? Does the old pit pond ever overflow,
or is it part of a huge "recycle system"? What's the receiving water, exactly?
See notes from site visit below.
• Subject to Tar -Pam buffer requirements? .Per 15A 2B .0259, that `old pond"
is considered surface waters but not subject per the rule (not shown on topo
map; the one you can see near the site is another old big mine pond at the site
next to it.
• What does "proposed vegetated filter" mean? Area that needs to have
vegetation better established at edge of pond (see photos of eroded channel at
the corner of the plant).
Site Visit, 2/4/2009
• Met Jinn Frei (consultant), Thom Edgerton (WaRO), Travis Smith (WaRO),
Myrl Nisely (RRO), and site representative (David Hardee?) at the plant site.
• Several recommendations for modifying treatment placement (i.e., move pH,
move pad for residuals, etc.)
• See photos attached.

NCG 140388
December 23, 2008
B. Georgoulias
Revised 3/5109
Receiving waters: Plant drains to a very large old mine pit that owners
referred to as "their stormwater pond." That pond connects to another large
pond (adjacent pits, basically). WaRO went back to the rear of the property
and could not find a likely place of overflow. In a very large event, could
possibly overflow towards a UT to Johnsons Mill Run (may be unlikely,
though). See topo map with pink and purple lines tracing out `unclassified'
streams in this area — the two ponds are not shown on that map, but the
watershed ultimately goes to Johnsons Mill Run.
Reviewer's Conclusion: Because we're dealing with wastewater discharges, the
General Statute is clear in (1) requiring a permit for any outlets into waters of the
State, and (2) not allowing waste discharges in violation of effluent limitations
established for any point source. (Citation is NC G.S. 143-215.1) DPD Team Concrete
thinks of this pond as "their stormwater pond," purchased from the previous land
owner —that was more or less just an old mining pit filling up —but that pond is still
considered 'waters of the State' (these are particularly large ponds, too). The
Definition in the G.S. (143-212) of those waters includes bodies of water, whether they
are public or.private, or natural or artificial,..." The NPDES program is the most
straightforward process for permitting the discharges. So, bottom line is discharges
from this plant site are going to the pond. Whether it can be considered `Class C' by
default or not is debatable, but will put 'Pond/ UT to Johnsons Mill Run' on the COC.
WS classification won't affect permit obligations, and DEH approval already
obtained. This decision is based on where DWR GIS layer of detailed hydrography
shows all waters in that area to be draining to.
Additional Information Review Summary, 315109
• Confirmed site not subject to Tar -Pam buffer requirements.
• Consultant verified road culvert discovered during site visit is buried and
abandoned (not a discharge point).
• Design relocated 1{ ortrans pH unit so wastewater does not circumvent
treatment.
Design now includes a drying pad for rinse pit residuals (rather than storing
them elsewhere on the property) so that water will drain back into the
wastewater treatment system. Residuals must be relocated to that area from
the original area indicated on the site plan to that wastewater is treated.
Site plan shows eroded channel will be modified to remove point source
discharge there. Drainage from aggregate pile wet -down is somewhat
contained by large block bins (see photos). Seepage may not be entirely
preventable but will likely be negligible, especially when channel repaired
and buffer is vegetated. Reviewer noted that as it stood during the site visit,
the eroded channel was considered a discharge point; however, modifications
should remove.

BUFFERS
Revised 3h109
The following is the management strategy for maintaining and protecting
existing riparian buffers in the Tar -Pamlico River Basin.
(1) PURPOSE. The purpose of this Rule shall be to protect and
preserve existing riparian buffers, to maintain their nutrient
removal functions, in the entire Tar -Pamlico River Basin, whose
surface waters are described in the Schedule of Classifications,
15A NCAC 2B .0316.
(3) APPLTCABTLITY. This Rule shall apply to 50-foot wide riparian
buffers directly adjacent to surface waters in the Tar -Pamlico
River Basin (intermittent streams, perennial streams, lakes,
ponds, and estuaries), excluding wetlands. Except as described in
Sub -Item (4)(a)(iii) of this Rule, wetlands adjacent to surface
waters or within 50 feet of surface waters shall be considered as
part of the riparian buffer but are regulated pursuant to
15A NCAC 2H .0506. The riparian buffers protected by this Rule
shall be measured pursuant to Item (4) of this Paragraph. For the
purpose of this Rule, a surface water shall be present if the
feature is approximately shown on either the most recent version
of the soil survey map prepared by the Natural Resources
Conservation Service of the United States Department of
Agriculture or the most recent version of the 1:24,000 scale (7.5
minute) quadrangle topographic maps prepared by the United States
Geologic Survey (USGS). Riparian buffers adjacent to surface
waters that do not appear on either of the maps shall not be
subject to this Rule. Riparian buffers adjacent to surface waters
that appear on the maps shall be subject to this Rule unless one
of the following applies.
(a) EXEMPTION WHEN AN ON -SITE DETERMINATION SHOWS THAT SURFACE
WATERS ARE NOT PRESENT. When a landowner or other affected
party believes that the maps have inaccurately depicted surface
waters, he or she shall consult the Division or the appropriate
delegated local authority. Upon request, the Division or
delegated local authority shall make on -site determinations.
Any disputes over on -site determinations shall be referred to
the Director in writing. A determination of the Director as to
the accuracy or application of the maps is subject to review as
provided in Articles 3 and 4 of G.S. 150B. Surface waters that
appear on the maps shall not be subject to this Rule if an
on -site determination shows that they fall into one of the
following categories.
(i) Ditches and manmade conveyances other than modified natural
streams unless constructed for navigation or boat access.
(ii) Manmade ponds and lakes that are located outside natural
drainage ways.
(iii) Ephemeral (stormwater) streams.

Thom,
Unfortunately the scanned version of this NOI is huge, and so I'm not going to fill up
everyone's email box before Christmas with something that huge. I will send the hard
copy on - to you through the mail after Christmas. Attached is a scan of the as --built
plans that I reference below.
This site is the DPD Team Concrete site in Greenville, located at 612 Barrus
Construction Rd. There is an outstanding question here about Tar -Pam buffer
requirements (not sure they're in compliance... the place is already built), so I've
copied both the Buffer Amy's in WaRO and here in the Central Office.
I did attached a .bmp of the map so you can see where this is located.
When you receive the NOI, let's talk about whether you need to pay a visit and how we
should proceed. The receiving stream they name downstream (Johnson's Mill Run) is
actually WS-IV; NSW, so I'm going to need DEH's approval for this as well. However,
the "surface waters" they apparently discharge directly to appears to be an old sand
pit "pond" that is also evident on the topo map (attached as well).
Hope you have a wonderful holiday!

Hello Jim,
I'm reviewing the N01/ATC application for DPD Team Concrete's plant in Greenville, and
I wanted to update you on the status. I'm still in the early stages, but I've found a
few things I wanted to go ahead and ask about so the holiday schedule doesn't delay
things too long (always a consideration around this time of year!):
-The receiving water is noted as a UT to Johnsons Mill Run in the Tar -Pamlico basin,
and the application says its classification is 'C' waters. However, our database
shows that waterbody is actually WS-IV; NSW. This is important because any discharge
of wastewaters into water supply waters must be approved by the Department of Health
in the Washington Regional Office. This is an extra step in our permit review, but we
cannot issue a COC under NCG14 without it. I plan to send the memo to request DEH's
input as soon as possible in January when I get add'1 info. from you on the other
questions I have. I just wanted you to be aware of this requirement. Also, it means
the project would be subject to any local Water Supply stormwater management
requirements, if applicable.
-The application in vehicle washing also takes place at this operation.
However, was this combined with assumptions about water used for drum rinse out (i.e.,
the 15 gal/cy assumption is for drum wash + vehicle wash/cleaning)? Please clarify
the basis.
-The application indicates that this site wets down aggregate piles from the "pond" as
a water source. It's unclear if this is the truck rinse pit, or the 'abandoned sand
1 of 2 12/23/2008 4: 18 I'M

[Fwd: D1'D Team Concrete - Greenville (NOI App. NCG 140388)]
pit' pond beyond the edge of the plant. Either way, ruri-off from this area is
therefore a wastewater, and the as -built plans do not provide detail about the
containment structures for those stockpile bins. if run-off from these piles flows
into the pond, it is considered a wastewater discharge. Where does the run-off from
the aggregate piles go? If it discharges to the pond, supporting information should
address how that discharge will comply with permit limits. If no discharges to the
pond are expected, then the application and site plan should clearly demonstrate why
not (for example, runoff from any storm event that contacts the piles will be
completely contained within the bins).
-This plant is located in the Tar -Pamlico River Basin, which has Riparian Buffer
requirements. From the as-builts, it appears the edge of the site is within 50' of
the receiving pond. If this is the case, not only does DWQ need to ensure the site is
in compliance with buffer requirements, but there is also a diffuse flow requirement
for any discharges (stormwater or wastewater). This may entail a level spreader
design requirement for the final discharge point, depending on whether the Riparian
Buffer requirements in 15a 2B .0259 are applicable to this location and the pond as
receiving waters. Did the company investigate buffer requirements prior to
construction of the plant, and/or do you know whether there were any exemptions from
those Buffer Rules granted based on an on -site determination? If you or the owners
are not clear on this point, we probably need the Washington Regional Office (WaRO) to
do a site visit soon to determine if there will be additional design requirements or
compliance issues as a result.
Thanks in advance for your help with this points, and I will be in touch with Mr. Thom
Edgerton in the WaRO after the Christmas holidays to coordinate review of this NCG14
application. I hope you have a wonderful holiday and Happy New Year.

Hi Jim,
Thanks for your response.
Regarding the "abandoned sand pit pond," I'm going to need the region's help in
determining what that is considered. it appears to be on the topo map, so I'd assumed
it to be 'waters of the state' and classified as we would other non -classified
waters: if a UT or other waterbody is not classified, it assumes the classification
of the nearest classified waterbody segment to which it drains. In this case, I
traced it down to Johnsons Mill Run, which is WS-IV; NSW. (In other words,
'unclassified' does not necessarily default to 'C' classification). Whether it can be
considered a stand-alone waterbody that does not flow downstream to a classified
segment and should be considered 'C', I'm not sure. I'll check with Thom at the WaRO
and with the staff in our Classifications and Standards Unit.
Thank you for the information about the vehicle washing.
As far as aggregate pile wetdown, the discharge is considered a wastewater (not
stormwater). That means the pit (or receiving pond, depending on whether it's surface
waters or not) is considered a wastewater treatment system -- not a stormwater BMP.
If water from it is being recycled to wet down the piles, it has essentially become a
wastewater recycle system. However, because it is not a system that qualifies with
design criteria imposed by the Non -Discharge program (concrete walls, etc.), it falls
under our NPDES discharge program. From one perspective, it could be a non -discharge
disposal system into the ground (if it all infiltrates), but if it overflows even
rarely, it is the most straightforward to permit it from our shop under NCG14. I
suppose the original question of whether the old pit is the receiving water or not
really turns into a question of whether it is a treatment device. If it is, potential
overflows/discharges go to the UT that flows to Johnsons Mill Pond.
I think a site visit by WaRO will probably be the best way to characterize the site
configuration and waters there. We may also need to confer with more staff here in
the Central Office to determine what is the recycle system and what is the receiving
water.
I will work with Thom Edgerton more on resolving whether the Tar -Pam setback applies
or not.
All the best for this New Year's 2009,

Subject: DPD Team Concrete - Greenville (NOI App. NCG14038B)
Hello Jim,
I'm reviewing the NOI/ATC application for DPD Team Concrete's plant in
Greenville, and I wanted to update you on the status. I'm still in the
early stages, but I've found a few things I wanted to go ahead and ask
about so the holiday schedule doesn't delay things too long (always a

consideration around this time of year!):
-The receiving water is noted as a UT to Johnsons Mill Run in the
Tar -Pamlico basin, and the application says its classification is 'C'
waters. However, our database shows that waterbody is actually WS-IV;
NSW. This is important because any discharge of wastewaters into water
supply waters must be approved by the Department of Health in the
Washington Regional Office. This is an extra step in our permit review,
but we cannot issue a COC under NCG14 without it. I plan to send the
memo to request DEH's input as soon as possible in January when I get
add'i info. from you on the other questions I have. I just wanted you
to be aware of this requirement. Also, it means the project would be
subject to any local Water Supply stormwater management requirements, if
applicable.
The entire site discharges/ sheet flows into the "abandoned sand pit pond"
which only discharges when it overflows during extremely large events
(actual return period not studied for overtopping event) into the UT to
Johnsons Mill Run. Neither the UT nor this pond is on the list of
classified waters in Pitt County (downloaded off the DWQ website). I
assumed if a waterbody is not listed, it defaults to Class C.
-The application indicates vehicle washing also takes place at this
operation. However, was this combined with assumptions about water used
for drum rinse out (i.e., the 15 gal/cy assumption is for drum wash f
vehicle wash/cleaning)? Please clarify the basis.
Yes, vehicle washing is combined with drum rinse. A vehicle is not always
washed when the drum is cleaned, but would typically be rinsed off at the
truck rinse pit during the last drum rinse of the day. There is no set
schedule for vehicle washing with detergents.
-The application indicates that this site wets down aggregate piles from
the "pond" as a water source. It's unclear if this is the truck rinse
pit, or the 'abandoned sand pit' pond beyond the edge of the plant.
Either way, run-off from this area is therefore a wastewater, and the
as -built plans do not provide detail about the containment structures
for those stockpile bins. If run-off from these piles flows into the
pond, it is considered a wastewater discharge. Where does the run-off
from the aggregate piles go? I€ it discharges to the pond, supporting
information should address how that discharge will comply with permit
limits. If no discharges to the pond are expected, then the application
and site plan should clearly demonstrate why not (for example, runoff
from any storm event that contacts the piles will be completely
contained within the bins).
Agg pile wetdown water comes from the "abandoned sand pit pond." The runoff
from the agg piles will sheet flow thru a proposed vegetative buffer into
the pond. If the operator considers this "abandoned sand pit pond" to be
his final downstream Stormwater BMP (a wet retention basin), then would the
runoff from the agg piles be a non -issue?
-This plant is located in the Tar -Pamlico River Basin, which has
Riparian Buffer requirements. From the as-builts, it appears the edge
of the site is within 50' of the receiving pond. If this is the case,
not only does DWQ need to ensure the site is in compliance with buffer
requirements, but there is also a diffuse flow requirement for any

Re: DPD Team Concrete - Greenville (NO[ App. NCG 140388)
discharges (stormwater or wastewater). This may entail a level spreader
design requirement for the final discharge point, depending on whether
the Riparian Buffer requirements in 15a 2B .0259 are applicable to this
location and the pond as receiving waters. Did the company investigate
buffer requirements prior to construction of the plant, and/or do you
know whether there were any exemptions from those Buffer Rules granted
based on an on -site determination? If you or the owners are not clear
on this point, we probably need the Washington Regional Office (WaRO) to
do a site visit soon to determine if there will be additional design
requirements or compliance issues as a result.
The plant was already built when I got involved. I do not know anything
regarding buffer requirements or prior exemption. That is a question for
David Hardee.
If the operator considers this "abandoned sand pit pond" to be his final
downstream BMP (wet retention basin), then would the setback from this pond
be a non -issue?
Thanks in advance for your help with this points, and I will be in touch
with Mr. Thom Edgerton in the WaRO after the Christmas holidays to
coordinate review of this NCG14 application. I hope you have a
wonderful holiday and Happy New Year.

Thom,
Please let me know when you've had a chance to review the materials for this project.
A site visit by at least the regional office will be very helpful. I'm not sure I'll
be able to go along (it depends on schedule, which is pretty full until February), but
we should try to determine what the receiving waters are, and whether the pit is in
fact a recycle system that should be included in the permit COC. In the meantime,
I'll prepare a memo to DEH for approval with the assumption that the UT to which it
overflows may be considered WS waters.
Jim,
Yes, concerns with the agg pile would be TSS or SS. However, if pH has become problem
in the pond from where the water is being recycled, then that parameter applies as
well.

Bethany G.

Good info.
The abandoned pit (now a pond) does not show as a blue pond on the
Greenville NW (rev 1982) topo - there is a large pond to the southwest, but
that is not "our" pond in question. I have seen a smaller pond within the
old sand pit on aerial photos (Mapquest), but our pond in now larger since
the dewatering pumps were removed when the sand mining operation ceased
(date unknown).
I suppose the'site was approved by the local jurisdiction (Pitt County or
Greenville) without a buffer requirement because they did not consider this
pond (basically a manmade hole that has filled with water) to be "waters of
the State". A separate stormwater BMP (ie. Detention basin) was probably
not required because this concrete plant occupies way less than 100 of the
total property.
What are your concerns with runoff from agg pile wetdown other than TSS?
Perhaps an on -site meeting with you DWQ folks, the owner, and me would be
useful. I would need a 5-7 day notice for a site visit.
Thanks.

Hello,
Thanks again for the mentoring today.
My thought is that the meeting today was left as, more information was to be provided
to Ms. Bethany, by either DPD Team Concrete or by Mr. Frei as to:
- an explanation to the origin of the corrugated metal pipe (CMP) outlet located on
the SW side of the property
- any redesigning of the treatment area to enhance the process by retreating runoff
from the rinse pit residuals
- means of preventing concentrated flow on the SW corner of the Dumpster / Sand &
Aggregate Stockpile Bins
- only using the rinse pit area for truck clean out
- providing a well established vegetated buffer.
I did not see any evidence that the ponds would overflow.
Please let me know if you need me to take any other action.

Hi Jim,
Thanks for the responses. Please see my comments inserted below.
jim frei wrote:
Good Morning Bethany,
I agree with most of your comments, except for these explanations:
Map 2:
1. SDO-COI is indicated at same location as PWD-002 because in some storm
events, runoff from a portion of the plant flows into the truck rinse pit
and through the Basin 3 outlet. This is the only point source for
stormwater discharge at this plant - all other runoff is sheetflow.
2. We are directing the operator to repair and eliminate the erosional
channel near the aggregate stockpile, thus there will he no point source
discharge at this location, only sheetflow runoff through the vegetative
buffer.
I understand that a process water sample is collected when discharge occurs
from the truck rinse pit on a dry day, and a stormwater sample is collected
when discharge occurs during a rainfall event.
No, this is not completely correct. Any water that flows into the truck rinse pit
mixes with the wastewater there and will always be considered a wastewater discharge
(whether during dry conditions during rinsing or overflow during rain). The flow does
not "become stormwater" when it is discharging as a result of a rain event. This is
why we are rigorous in requiring applicants to demonstrate compliance with limits (not
cut off concentrations for stormwater) under design storm conditions. Even when the
plant is not operating but slurry/solids from the process are sitting in the bottom of
the cells, the water is contacting a waste and therefore wastewater.
Map 3:
1. Operator stated during the field visit that he will install a floating
pump in Basin 3 to pump water for use in concrete mix (adjust slump after
trucks are filled from silos), and to rinse trucks before they leave the
site. Pumping will not affect settling calcs as pumping will occur from
upper several inches of water and before discharge from Basin 3 occurs.
Location of pump will be indicated on Map 3.
2. By starting Basin 3 water.level below its outlet immediately before
truck rinsing commences, short-circuiting thru Basin 3 is prevented.
However, since operator will need a separate tank to hold 2 inches of
pump -down water, and cannot commit to this expense, the note on Map 3 will
be deleted.
Water loss due to evaporation will keep the water level in each basin below
the weir notches most days, therefore during most truck rinse operations,
the rinse pit is a closed system unless outside water is added.
Regarding wastewater discharges into the pond, will benchmark values similar
to other general stormwater permits (i.e., pH = 6.0-9.0 and TSS < 100 ppm)
be required?
Effluent limitations apply to any wastewater discharges. When the permit is renewed
this year, I anticipate the stormwater discharge part to look similar to other general
permits, with benchmarks rather than "cut-off concentrations," and those
parameters/values are pretty standard. However, those benchmarks apply to any
1 of 4 2/16/2009 11:21 AM

Re: DPD Team Concrete #NCG 140388
stormwater only discharges. Anything that mixes with wastewater is instead subject
to limits. At this site, all indications are that point sources of discharge are
going to be considered wastewater.
Just as an FYI - if the system were submitted as a closed -loop recycle system, we'd
require assumptions and calculations about exactly what portion you're assuming will
evaporate and under what conditions (i.e., just saying, "a lot's going to evaporate so
it probably won't overflow" -isn't sufficient). It's not an issue here because the
application provided settling calculations to demonstrate treatment during the 10 year
event. I only mention it because we see this sometimes in applications trying to
demonstrate closed -loop recycle conditions, and we have to emphasize that we need to
see specific assumptions about volumes in a water balance.
If you have any other questions before you submit the materials you're preparing, just
let me know.
Thanks,
Bethany G.

Hi Jim,
I have some comments, but overall you have addressed the major issues we
talked about during the site visit.
Both Maps:
t4 otation says 'This drawing represents As -Built Conditions'; however,
you are noting proposed changes on these as well. To be accurate, I
would recommend revising to say 'This drawing represents As -Built
Conditions with Proposed Modifications identified' (or something like
that).
,/,-,ap 2 (Entire site):
The modifications proposed to the treatment system (residuals drying
�rea and pH adjustment at the end of the last cell) look good.
-You note both a process water discharge sampling point (PWD-002) and
stormwater discharge (SDO-1) at the end of the treatment system. Advise
removing the reference to stormwater (SDO-1) because this will be
considered a wastewater stream only (not stormwater).
-Might note potential wastewater sample point at eroded channel, but
that repairs could eliminate it. As it is today, it's a discharge point,
and unless water seeping from the aggregate piles (that are sometimes
sprayed) can be completely segregated or retained, this will commingle
wastewater with stormwater running into the pond during rain events.
[dap 3 (Truck rinse system):
v-See above comments regarding sampling point
See above comments regarding notations re: As -Built Conditions
-Plans note that Basin 3 will be pumped down at least to 2" below outlet
before releasing water from Basin 3. Where is the pump to be installed,
and would this be consistent with the settling calculations originally

Re: DI'D Tean3 Concrete 9NCG 140388
submitted (by M. Walker, P.E.) to show compliance with TSS limits? Don't
those calculations show detention times that are based on gravity flow
through over the weirs in both dry conditions and rain event scenarios?
Please reconcile any discrepancies that could compromise treatment
capacity/settling times.
A word about the receiving waters at this site:
I know the question came up early on here about what the receiving
waters actually were. We started out calling it a UT to Johnsons Mill,
assuming the old mine ponds could theoretically overflow towards the
watershed of one of those tribs. Our site visit indicated it would
probably take an unusually large storm event for that to ever happen
(though presumably the aquifer is connected, so it does get there one
way or another). Here's what I've concluded about this situation:
Because we're dealing with wastewater discharges, the General Statute is
clear in (1) requiring a permit for any outlets into waters of the
State, and (2) not allowing waste discharges in violation of effluent
limitations established for any point source. (Citation is NC G.S.
143-215.1) I realize DPD Team Concrete thinks of this pond as "their
stormwater pond" that they purchased from the previous land owner --that
was more or less just an old mining pit filling up --but that pond is
still considered 'waters of the State' (these are particularly large
ponds, too). The Definition in the G.S. (143-212) of those includes
bodies of water, whether they are 'public or private, or natural or
artificial,..." The NPDES program is the most straightforward process
for permitting the discharges. So, bottom line is discharges from this
plant site are going to the pond, and I'm going to have to figure out
the best way to document that on the permit COC & map.
Just let me know if you have any questions..
Have a great weekend!

Application Return (Return #1197)
Pitt County
.-Dear Mr. Hardee:
On October 24, 2008, the Division of Water Quality received your Notice of Intent (NOI)
requesting coverage and an Authorization to Construct (ATC) under general storrnwater and
wastewater permit NCG140000.
The application did not include three.(3) copies of plans and specifications showing
details about where the CO2 feed.systel"n-for pH adjustment will be installed.- The application
also did not include copies of as built W r the current wastewater treatment system, signed
and sealed by a P.E. Given the relatively recent construction of this plant site, we anticipate
these plans to be.readily available ----so if they are not, please -provide an explanation. Be sure -to
include all of this information when resubmitting the. application.
The Stormwater, Permitting Unit (SPL }. noted this site was developed in 2007. It appears
that your company did not obtain an NPDES discharge permit for this site, nor did it obtain
an Authorization to Construct (ATC) wastewater treatment systems prior to operation.
With this letter, the Central Office is recommending that the Washington Regional Office
investigate non-compliance of this site further, as necessary.
Please note that ATC requests must be submitted at least 90 days prior to construction.,
and that an ATC is required for treatment facilities used to treat or recycle process wastewater.
Please keep this 90-day timefrairle in mind for any future. projects that involve wastewater
treatment or 'recycle systems.

DPD Team Concrete, Inc.
Greenville, NC
Background
The existing concrete batch plant is located at 612 Barcus Construction Road in Greenville, Pitt County,
NC and is situated on the east site of Ban -us Construction Road. The 73.3 acre site was developed in
2007. Stormwater management facilities were constructed at the time per state requirements.
The property is generally flat with only gentle slope constructed when the site was developed.
Approximately 10% of property is gravel traffic areas and 0.5 % is impermeable (buildings, concrete,
etc.).
Existing Stormwater Management Facilities
Ground slopes designed to direct runoff to the stormwater management facilities, which is the abandoned
sand pit/retention pond. The pond discharges to an unnamed tributary of Johnson Mill Run.
A concrete truck drum wash area is located near the rear (east site) of the batch plant and west of the
pond. Drum wash water is collected on the concrete pad and drains directly into Basin 1 of a three basin
wastewater control facility. Additionally, about 14,004 SF of the batch plant area (including the area of
the silos) drains to Basin 1 of the wastewater collection facilities. Basin 1 contains a volume of
approximately 1,821 ft . Wash water overflows Basin 1 through an opening in the top of the wall and
enters the 1,821 ft Basin 2. Through another opening, wash water overflows into the final basin (Basin
3), which has a capacity of about 3,000 ft , The overflow discharge flows over the land surface, through a
proposed vegetative buffer, and into the abandoned sand pit/retention pond. It is estimated that a
maximum of 6 loads (drum washes) will occur per day, yielding approximately 180 fl (1,346 gallons) of
wash wastewater per day.
Wastewater Control Measures
The existing stormwater control facilities were evaluated for their ability to capture suspended solids in
the drum wash wastewater. The analysis shows that existing basins will capture 100% of suspended
solids.
pH control will be required. DPD Team Concrete will install a CO2 feed system (by Fortran) to
neutralize the high pH wastewater in Basin 3.

Task: TSS passing basin 2 Sheet 4 Of 5
Estimation of TSS from basin 2: (from cement)
Concrete trucks will be washed out after every load. It is expected that 130 lbs of concrete will washed from each
10 CY truck load or 13 lb/CY.
The design for portland cement on this project is approximately 530 lbs/CY and the average CY of concrete weighs
4,000 lbs. therefore the weight of cement averages 13% per CY of concrete.
Waste concrete at 15 lbs/CY with 14.1% of the weight coming from cement will yield 2.1 lbs/CY of cement that
will adhere to the truck and be included in the wash water.
See weight of concrete settled per basin calculations.
*Suspended cement discharging from basin 2 during rain event— 0.00 lbs
*If operations ran during rain events, which they will not.
To be conservative assume that 30% of the settled particles discharge to basin 2

FORTRANS pH CONTROL SYSTEMS
FORTRANS pH CONTROL SYSTEMS are
completely automatic. They continually monitor/test
the pH of the influent water and compares it to the
PH setting of the control unit. If a change in pH is
detected, the controller activates the solenoid valve
for the CO2. The pH adjustment chemical is then fed
to the return side of the circulation pump until the
PH is again at the proper level set at the controller.
The unit will continuously circulate the water until a
change in pH is detected and the treatment cycle
begins once again. The unit also features a digital
PH meter connected to a probe in the sample cell
to ensure unit is functioning properly and that the
correct pH level is maintained.
The pH CONTROL SYSTEMS are designed to
treat and maintain a specified pH level in a body of
water usually 100,000 gallons or less to allow the
permitted discharge of treated water to the
environment. Permits must be obtained from the
local governing agency to allow any discharge to the
environment. Treated water may be used for wetting
of rock and/or dust control to aid compliance with
stormwater runoff regulations. Treated water may
also be used in water recycling systems.
These systems offers precise monitoring and
control of the pH in settling basins, lagoons and
other outfall containment devices.
-The pH CONTROL SYSTEMS will treat up to
57 gallons per minute - max 20' head pressure.
Unique water circulation design eliminates the need
for separate neutralization tank.
•1.5" quick connect fittings on inlet and return
for easy hook-up. The standard unit is equipped with
2-30' sections of 1.5" flexible hose with quick connect
fittings. Inlet and outlet fittings at the basin or lagoon
are per our specifications.
-Unit is shipped completely assembled. The
chemical controller is preprogrammed to maintain a
PH of 7.5. Just attach hoses and PVC fittings.
-1 year warranty on all component parts
and housing.
PERFECT SOLUTION
The Model 5000-S pH Control System is a self-
contained pH monitor and control system housed in
a weatherproof facility with lockable doors and
adequate space to house the instrumentation and
circulation pump. The system is configured for carbon
dioxide gas operation.
The Model 5000-SK Skid Mounted pH Control
System contains all of the instrumentation and
components of the regular Model 5000-S System
and is shipped on a 44"x47" plastic skid with a durable
solid plastic surface. The Control Panel is provided
loose with all components installed and is designed
to be attached to an interior wall of the control
building. The tubing to the sample cell and from the
CO2 solenoid valve to the Sparger stone feed
assembly must be inserted after receipt of the unit.
The system features a 115V-30Amp Breaker Box
and two GFCI receptacles. The system is shipped
with a CO2 feed system.
