Subject: Rescission- of NPDES Stormwater Permit
Certificate of Coverage Number NCG140351
Cabarrus County
On August 10, 2017, the Division of Energy, Mineral and Land Resources received your request
to rescind your coverage under Certificate of Coverage Number NCG140351. In accordance
with your request, Certificate of Coverage Number NCG140351 is rescinded effective
immediately.
Operating a treatment facility, discharging wastewater or discharging specific types of
stormwater to waters of the State without valid coverage under an NPDES permit is against
federal and state laws and could result in fines. If something changes and your facility would
again require stormwater or wastewater discharge permit coverage, you should notify this office
immediately. We will be happy to assist you in assuring the proper permit coverage.
If the facility is in the process of being sold, you will be performing a public service if you would
inform the new or prospective owners of their potential need for NPDES permit coverage.
If you have questions about this matter, please contact us at 919-707-9200, or the Stormwater
staff in our Mooresville Regional Office [phone].

Cabarrus County
Dear Mr. Houser:
In accordance with your application for a discharge permit received on January 3, 2005,
we are forwarding herewith the subject certificate of coverage (COC) to discharge under the
subject state — NPDES general permit. This permit is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the US Environmental Protection Agency dated May 9, 1994 (or as -subsequently
amended).
The NCG140000 general permit covers discharge of stormwater and process wastewater.
During the application process, you demonstrated that the recycle system at this plant will
recycle all process wastewater associated with activities at the facility, even in the event of a 25-
year, 24-hr storm, and that the facility does not intend to discharge any process wastewater. In
the event that process wastewater discharge does occur, the discharge must meet all applicable
effluent limitations in the permit.
We understand that the system has already been built; therefore, an authorization to
construct was not issued concurrently with this COC. Please ensure the attached Engineer's
Certification is completed and returned to verify that facilities have been constructed in
accordance with the design criteria noted above.
Please take notice that this certificate of coverage is not transferable except after notice to
the Division of Water Quality. The Division of Water Quality may require modification or
revocation and reissuance of the certificate of coverage. This permit 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 that may be required.

In response to the Division of Water Quality (D1VQ) letter dated April 19, 2005 rcgUcstllig
additional information for the above rcferenced facility, as well as phone conversations between
DWQ and Macleod Construction, Inc, (Macleod), the attached information has been prepared as
relates to pending stormwatcr permit I'or the Macl-cod Harrisburg plant,
fhc fi)llowing information is included in the attached documentation:
a) Drainage area and associated ]0-year 24-hour rair7f:11] cvcnt stormwatcr runoff volume from
the MacLeod facility as calculated and scaled by MD11sour E(lin, PE with ManSoLlr i-diin
Consulting.
b) Calculation spreadsheet including:
i. Total throughput of water at the facility, ine lading water used ill concrete mixing and
the above referenced 10-year 24-hou1- rainfall went. Ail information used in thcsc calculations
was based on real oper•Uting numbers and information included in "i" above.
ii. A comparison of the total potential water usage at the facility and the capacity of the
recycle system at the facility. The calculations illustrate the ability of the facility's water rccycic
system to handle the potential water throughput.
c) Calculation spi-cadshect identical to "b" above, howCVer, runoff volume Was calculated Using a
25-year, 24-1101.11' rainfall even[ (all facility -specific information for the 25-year 24-hour
calculation is the same as included on the 10-year 24-hou1- runoff document referenced in "a"
abovc. The inches of rainfall from a 25-year 24410ur event was determined using the North
Carolina Erosion and Sediment Control Planning and Design Manual, September 1988).
d) In the extreme case of an overflow ofwater from the recycle system into the stormwatcr
detention pond, MacLeod has a contingency plan in place to monitor and adjust the pl-I ofihc
stormwatcr detctition pond. The plan is based on cUrrcnt protocol at another MacLeod facility.
MacLeod construction wishes to do everything possible to reach a resolution regarding
stormwatcr permitting 101- their new Harrisburg facility. The facility wishes to operate later this
month, so anything that can be done to expedite the permitting process would be greatly
appreciated. Also, please feel free to call me or my cnvironrncntal consultant, Ms. Alissa L.
Williams of URS Corporation, if yOU have any guestions regarding the attached information,
`[hank you for your time and consideration.

Dear Michael:
In response to the DENR letter dated April 19, 2005, we have prepared the
following calculations regarding the drainage area for the recycle system.
Contributing drainage area: 0.30 acres (13,068 square feet)
10-yr, 247hour rainfall: 4.8 inches
Runoff coefficient: 0.95
Runoff volume from the drainage area: Q
Q = 13,068 x 0.95 x 4.8 x 1/12 = 4,965 cubic feet, say 5,000 CF
Volume of settling tanks:
3 x 1,296 cubic feet per tank = 3,888 CF
Volume of clean water tank: 7,200 CF
Total volume: 11,088 CF
Should you have further questions, please feel free to contact us.

NPDES Application No. NCG140351
Cabarrus County
Dear Mr. Houser:
The Division of Water Quality (DWQ) Stormwater Permitting Unit has reviewed your NPDES
Permit Application for General Permit NCG140000, received January 3, 2005, and additional
information submitted through Mr. Mansour Edlin, received March 24, 2005 and April 7, 2005.
We feel more detail about the recycle system design and proposed method of pH control is
necessary before a permit can be issued. This request is not meant to unduly delay your permit;
however, the permit applicant must provide sufficient evidence to reasonably assure DWQ that
the proposed system will comply with applicable water quality standards and requirements (per
15A NCAC 0.2H .0112). Unlike most other stormwater general permits, this NPDES permit is a
combined wastewater and stormwater permit, and therefore our review must also consider
process wastewater discharge and treatment —not just stormwater controls.
Our previous requests for design basis information have yielded some details about the recycle
system but have not demonstrated the design storm capacity, or whether pH will be controlled
sufficiently in the event of overflow. Please provide more comprehensive design details and
calculations as outlined below.
Recycle System Design
Please explain assumptions regarding:
• The drainage area to the recycle system. Earlier responses noted that the drainage area is
"limited to a small area on the north side of the recycling system." Please quantify the
area incorporated into the design, and describe the drainage divides that define the
contributing area.
• Assumed daily throughput flow and basis (e.g., assumed number of nzix drum washouts
and amounts, estimated vehicle splatter wash down flows, etc.). Please quantify the
design basis for all types of process wastewater and stormwater flows that the recycle
system will handle.

• Settling and residence time assumptions. What settling volume is provided in the settling
tank cells, and what settling velocities were used for the design? Please provide
calculations demonstrating that the system will remove total suspended solids (TSS)
down to the permit limit of 30 mg/l in the event of an overflow. If meeting permit limits
relies on additional treatment in the stormwater detention pond, please demonstrate how
the detention pond design incorporates recycle system overflows (flow and any additional
solids loading) and will ensure discharge meets the 30 mg/l TSS limit and 5 ml/1
settleable solids limits.
0 The amount of freeboard that will be maintained in the clean water tank under normal
operating conditions.
pH Control
• How will the pH be monitored?
• How will operators ensure sufficient dosage and mixing time prior to discharge? Please
explain the protocol that will be used to measure and adjust the pH. Will chemical
adjustment occur in the clean water tank or in the detention pond? If the recycle system
is designed to contain the 10-year storm —the same as the pond —process wastewater and
stormwater will commingle in rainfall events of that magnitude (and discharge from the
outfall will be considered wastewater). How will pH be adjusted and controlled prior to
discharge?
• How was the amount of muriatic acid to be stored on site estimated? Please provide
calculations used to estimate the dosage necessary to reduce the pH from 12 to 8 under
design conditions loading.
We appreciate your assistance in addressing these concerns. Please provide the requested
information by May 4, 2005. If you have any questions, please feel free to call me at (919) 733-

Re: NOI application for McLeod Construction
Ready -Mixed Concrete Plant (East Plant)
Cabarrus County, COC# NCG140351
Dear Bethany:
In response to your request for additional information regarding the above
referenced application, we are enclosing the following documents:
1. Layout of recycle system furnished by MacLeod Construction
2. Copy of the grading permit issued by Cabarrus County
3. Site grading & drainage plan showing the sampling point
Furthermore, we have discussed the review comments dated February 22, 2005
with Mike Houser, the Operation Manager for MacLeod Construction, and offer
the following response to each of the comments which are listed below.
1) What is the design basis of the recycle system? (The NOI application
specifies that design specifics such as design volume, retention time,
surface area, etc.be included for recycle systems.) The NOI notes that
the system does not overflow only during rainfall events exceeding the
10-yr, 24-hr rain event; what storm is the system designed to handle?
The drainage area associated with the recycling system is limited to a,5mall area
on the north side of the recycling -system, -Most of the surface runoff from the
parking_and_site_doe to rain-into-the_recycling_sy_gtem. The proposed recycling
system is designed to contain the 10-yr storm event.
sr% �r

. .f
2) The footprint of the detail presented on the recycle system (attached
to the NOI) does not match the recycle system presented on the Grading/Drainage Plan. Please
explain the inconsistencies and provide a
corrected Plan or footprint detail.
Attached is the correct recycle system is for this project, which consists of the
following components:
• Sand & stone reclaimer
• Slurry dry pit ✓���,,ry c ��a�
• Slurry tank with a capacity of 3,744 CIF
• Three settling tanks with a capacity of 1,296 CIF per tank
• Clean water tank with a capacity of 7,200 CIF"' (oZ�i"� ��s %
3) What is the purpose of the multiple 6" PVC pipes that run from the I `{ �7►�
A h 1 f (
recycle system to the stormwater pond . re t ese conveyances on y or � ¢jz n
overflow situations? (Keep in mind that if storm water and process PtSGa�e—
wastewater commingle, the discharge is considered wastewater and subject
to permit limits).
According to MacLeod Construction, there will be one 6" PVC pipe for the
purpose of the conveyance of storm water during overflow situations only. The
design intent is not to discharge storm water from -the —recycle system into the
storm water pond.
4) The NOI application indicated vehicle equipment cleaning, aggregate
wetdown and mixing drum cleaning activities would all be occurring at
thisJfacility; however, the location of these activities and material
stockpiles, and where the associated wastewater will drain to, are not
explained or shown on the plans. Please describe where these activities
will take place, where the water will drain to, and how these waters (if
recycled) will be kept separate from stormwater. Also, please provide a
revised Plan or other detail to show where the wastewater from these
activities will be directed.
���5_S
� r c-•�C G, � z��
The -vehicle equipment cleaning is not envisioned. There will be no vehicle "car
wash" area. The cleaning of vehicles will be limited to removal of load splatter on
chutes, the cleaning of catwalk area(s) at the mouth of the drum for the operator,
safety reasons, clear top of cab area of load splatter (front discharge mixer) for
safety on highways, and cleaning of Tixer drums. Those activities will -take place
'i the reclaimer area. �-

5) Process wastewaters from ready -mix plants typically have very high
pH. Water quality standards (and NCG14 permit limits) require any
discharge from these facilities to meet a pH of 6-9 su. How will pH be
corrected if wastewaters are discharged? This step is essential if any
process wastewaters are not directed to the recycle system. (if plans
are to recycle 'all' process wastewaters, please specify. Again, this
emphasizes the need to demonstrate adequate design of the recycle system.)

. 4 k
It is the intent to discharge zero water from the plant production area. Tanks are
designed to hold a�l water from production area and re -use it in mixer and/or
reclaim areas. (In the unlikely event of a breach, and water does proceed to the
lower earthen pond, we will monitor the PH and adjust through the use of
approved chemicals).
6) Please provide documentation verifying that the applicant has
developed and submitted any required Erosion & Sedimentation Plan for
approval to the Division of Land Resources or designated local
government (per NCAC 15A 02H .0138).
The Erosion & Sedimentation Plan has been reviewed and approved by
Cabarrus County. Attached is a copy of the permit issued for this project.
A couple of more minor issues I'd also like to follow up on:
7) Please identify where sampling points will be.
The proposed sampling point will be the discharge point of the 18" storm water
pipe leaving the storm water pond.
8) 1 noticed flow calculations were dated more than two years ago (July
2002)... are these the correct calculations for this project, and was
there just a significant amount of lag time between the initiation of
this project and the design plans?
What you have on file are the correct calculations for the storm water pond.
Should you have further questions during the review process of the permit
application or the enclosed documents, please feel free to contact us.

Subject: Peer review on NCG 140351
From: Ken Pickle <[e-mail]>
Date: Mon, 14 Feb 2005 12:17:51 -0500
To: Bethany Georgoulias<[e-mail]>
Bethany,
A couple of things caught my eye on McLeod Construction.
1. The consultant presented stormwater calculations and you checked the stormwater
pond size against the SA/DA table - - good.
I'm confused about the design of the wastewater recycle system on several counts.
a) There is no design narrative sufficient to tell me what the design basis is. My
approach on the few sNCG14s that have wastewater components has been to consider that
the submittal should be viewed very similarly to a wastewater submittal to the NPDES
wastewater unit. That is, before we can issue the permit, we need at least a
rudimentary engineering understanding of what's happening with the wastewater. Maybe
not to the degree that our wastewater folks require, but at least we should know what
the treatment processes are, and what the flow path is. The applicant has not shown
that to me in a way that I can understand it.
b) Because this permit has a wastewater component, our issuance of the permit is also
an issuance of the authorization to construct. Just like in wastewater, we are
authorizing not just the discharge, but the construction of treatment facilities.
That deserves an engineering review. I don't think we need to check concrete specs,
rebar sizing, pavement thickness, pipe hydraulics, etc. But I do think that with my
background in design, and your background in wastewater that a gross review of the
construction sizing, similar to the SA/DA check that you performed, is appropriate.
One thing we might want the designer to identify is what is the design rain for the
recycle system, i.e. when has he designed it to overflow?
,/ c) I'm concerned with the multiple 6" PVC pipes that seem to rtin from the recycle
system to the stormwater pond. 'what's that about? I guess it's some kind of
overflow, but there's no design narrative to tell me that. They could just be a
normal discharge, meaning the system will only "recycle" when it's not raining - I
think we would have a problem with that design for wastewater. The designer needs to
tell us in a way that we can understand what's going on. He should be aware that at
some threshold, if he combines the wastewater discharge with the stormwater, z think,
NCG14 requires him to teat t e whole flow as wastewater. Meaning he will have limits
on the combined discharge. Maybe that's ww2Tat-1fe1-s a ter —some kind of dilution
effect?? It would help if the designer would identify how the features of his design
mesh with the permit requirements and the permit differentiation between stormwater
and wastewater discharges.
d) It seems to me that one of our tasks in an engineering review is to get a sense of
whether or not the design details all sort of "hang together". I realize, we
certainly can't "re -engineer" the facility. That's not our job, and it's not
appropriate in a professional sense. But we should get an idea of how the design
measures up with regard to the internal rigor and the correlation with the
requirements of the rule and permit. One sign is whether the submittal documents are
internally consistent. It does not appear to me that the footprint of the detail
—'presented on the recycle system matches that presented on the Grading/Drainage Plan -
they don't appear internally consistent. Further, it is worth questioning, I think,
why the calculations presented are sealed and dated September '02, but the drawings
presented are sealed and dated December '04. It may be that there is a good reason
for the two-year lag in time. Maybe it takes two years to design a ready mix plant -
I don't know. I think it's worth asking about.
3. Also, the regions have been on an enforcement emphasis with respect to the ready
mix industry for over a year, I think. It's my impression that they are also
preparing to rachet-up enforcement again. I think we can support their efforts to
of 2 2/14/2005 12:1 8 PM

imap:[e-mail]:143/fctc...
get the industry compliant by using our required review during the permitting process
to be sure that good recycle systems are installed.
4. Further, he has checked the box indicating aggregate wet -down as a process
wastewater source. But I don't see the aggregate piles on the site plan. Where are
hey? Where do they drain to?
5 uther, we know that process wastewaters from ready mix plants have high pH, and
that the permit requires that the pH be between 6 and 9. Absent a design narrative,
nd with no indication of.pH correction equipment on the Grading Plan, I conclude
that the design does not include a pH correction step.' It is not approvable as
submitted.
n Further, he has indicated that vehicle cleaning will be taking place. But that
D'activity is not located on the Grading Plan. We don't know where it is draining to,
�!( /therefore we don't know if that water is intended for the recycle system, or would
V it be illegally discharged in the stormwater?
7. Further, he has indicated that mixing drum cleaning will be taking place. But the
location on the submitted documents is not identified. I presume that the recycle
1 ystem configuration indicates that the wash out will be on a ramp adjacent to the
A/recycle system. But that's an un-authorized assumption on my part. The documents
need to tell us where drum clean out will'be.
Given the lack of effective communication of the features of the design, it seems
to me we may want to encourage a more complete communication with this designer.
Specifically, we may want to ask him to identify the sampling points on his Grading
Plan. This sort of request is standard in the wastewater permitting world.
Recognizing that the location of samples may influence the physical construction of
the facility, I think we need to help the designer include this feature in his design
submittal to us.
9. Finally, I think we are supposed to add the blank Engineer's Certification page to
the permit package. That's the form on which we require the design engineer to
attest that the system has been constructed in accordance with the plans submitted to
us.

MacLeod Construction —Harrisburg Plant
rev. 6/6/05
Summary
This facility submitted a Notice of Intent to be covered under General Permit NCG140000
(Ready Mix Concrete). This facility will be a concrete ready mix plant. The stormwater
discharge drains to Back Creek, a Class C stream in the Yadkin -Pee Dee River Basin. This
facility is located in Cabarrus County, handled by the Mooresville Regional Office.
Application review
a) The permit application has been signed and sufficiently completed. Yes.
b) The SIC code accurately describes this facility's activities and is covered by this
general permit. Yes. SIC: 3273 (Ready -mix Concrete)
c) Does this facility have other permits? No.
d) Hazardous Waste Activities? No.
e) StormwaterBMPDesign Review:
Design Engineer used Hydraflow program to determine peak discharges from
hydrographs. Wet detention basin appears to be sized adequately for 77%
impervious area; SA/DA ratio = 0.036 is > 2.78 % (from Table 3.3-1 for 80%
impervious area in 2004 Draft BMP Manual, Section 3.3.6). Appropriate basin
L:W ratios and slopes.
WW treatment Design Review:
Several issues that need to be resolved before Authorization to Construct (AtC)
can be issued. See 2/22/05 add. info. request (e-mail and fax). Add, info
received 3/24 and 4/7 (M. Edlin), and 6/2 (M. Houser, prepared by URS).
-The recycle system is designed for the 10-year storm (consistent with threshold
above which permittee would not have to sample during overflow event;
however, any discharge must still meet permit pH and TSS limits).
-Copy of approved E&SC Plan from Cabarrus County submitted.
-Sampling point added to plans.
-Footprint includes more labels but still somewhat discrepant from plan...? Are
the stone and sand reclaimer areas not on the grading plan? Is that rectangular
tank on the back end (labeled "Bottom 622") of the system omitted from the
footprint?
PerM. Edlin 4/1:
Footprint is most accurate and should stand as an attachment to the plan.
The rectangular portion at the back is in fact the clear water tank (and slurry
tank), as on the footprint.
-Only one 6" PVC pipe will run from the recycle system (from where? On plan,
comes from back partition... is that the clear water tank indicated on the
footprint, or is it from the last settling basin? Is there a rectangular basin on the
back to capture overflow that is not on the footprint?), and is for overflow

situations only. How high up is the pipe, and how much freeboard will be
maintained?
Per M. Edlin 411:
Yes, overflow pipe routes water from clear water tank (only upon overflow),
where water is withdrawn for recycling. Will follow up with client on vertical
detail to demonstrate how high the pipe will be installed, and what kind of
freeboard will be maintained in typical operating situations, per reviewer's
request.
Per Faxed Response, 41 T
The pipe is 10' off the bottom of the tank and 4" from the top of the tank.
(**No info. on amount of freeboard provided). Water in the clean water tank
will be used in the mixer for batching and used at the reclaimer. Note —per
info. on 6/2, overflow pipe will not be used —plugged. Capacity of entire
tank (7200 cu. ft. available).
-Cleaning of vehicles to remove load splatter from chutes, etc. will occur in
reclaimer area; if this is the case, runoff should route to recycle system. What
about aggregate wetdown? Where will those piles be stored? If near bins, run-off
could drain towards parking lot and directly into pond. [This might be a concern,
depending on amounts discharged to pond ... need to ensure solids and pH limits
could still be met.]
Per Edlin 411:
Mostly likely aggregate materials just stored in bins and run down on
conveyor system, where water would be conveyed down to plant. However,
will follow up with client on this item.
Per Faxed Response, 41 T
Aggregate will be stored in underground bunkers and will not require wetting.
-Asserts that in the event of a breach (overflow) to lower earthen pond, pH will be
monitored and adjusted through the use of approved chemicals. Note —then this
better be addressed in the facility's SPPP (what chemicals are to be used, how
they are stored, etc.)
PerM. Edlin 4/1:
Will follow up with client.
Per Faxed Response, 417:
Muriatic acid (hydrochloric acid solution) will be used but not stored in bulk
on site. Permittee will purchase gallon jugs from local supplier as needed and
keep about 4 gallons on site.
**Is this enough? Calcs to show this, or dosing amounts for a site with
similar production to compare it to?
**Still no information about retention time, throughput assumptions, drainage
area to the recycle system, etc. to verify it's designed for the 10-year storm.
Per Add Info. from URS submitted 612:
-Assumptions for recycle system throughput based on concrete mix water,
washout water, splatter rinse outlined clearly. Including concrete mix water is
conservative —a significant portion should leave the site in the mix in trucks.

NCG 140351
January 19, 2005
B. Georgoulias
-Through-put calculation uses runoff from entire site, a conservative estimate
because a portion (stormwater only) will not drain to the system (good safety
margin)
-Balance on system for both 10-yr and 25-yr storm events demonstrate capacity is
sufficient to hold both with over 2500 cu. ft. excess volume left over.
-Based on dimensions of the clean water tank and settling tanks and through -put
calculations, excess volume should provide at least F of freeboard even in a 25-
year storm event (with rainfall amount included). [Note --proposed Non -
Discharge rules for Closed -Loop Recycle Systems (15A NCAC 02T .1003,
attached) will permit by rule rinse water recycle systems at concrete mixing
facilities that meet these same criteria.] Reviewer recommends approving permit
without requiring more info. on waste treatment capability —if system will not
overflow during a 25-yr storm event with conservative through -put assumptions,
reasonable to consider it non -discharge. (AtC would normally still apply b/c
recycle system still considered ww treatment, but site has already been built, so
won't include on COC.)
f) Regional Office input requested: 01/21/2005
RO Approval received: 01/26/2005 (via e-mail from Mike Parker.)
g) Application approved? Yes. Demonstrated recycle system is closed -loop and
capable of containing the 25-year, 24-hr storm event with allowance for
reasonable freeboard —should be no wastewater discharge. AtC moot —
system already built. Company has also committed to a contingency plan for
pH control in the unlikely event of an overflow. COC issued with Engineer's
Certification form.
Phone/Fax Logs
2/22/2005: Spoke briefly with consultant Mansour Edlin. E-mailed additional
information request. (Copied message to facility contact Michael Houser with
MacLeod Construction, via fax).
3/3: M. Edlin phoned to briefly go through request; will meet with Mr. McLeod to
clarify design issues.
3/30. Phoned M. Edlin to follow up on remaining questions (lft mssg).
4/1: Spoke with M. Edlin re: remaining questions. Will follow up with client and
call back.
4/7: M. Edlin Faxed responses to questions.
4/ 18: Spoke to M. Edlin—let him know we need more on recycle system design and

B. Georgoulias
4/28: Discussed add info. request with Mike Houser (704-483-3580, ext. 11; cell 704-
400-8919); company intends to build a non -discharging (closed -loop) recycling
system. Original plans put together by company's owner and his father;
documentation of plans not readily available. Difficulty with M. Edlin preparing
and submitting application in timely fashion. Employing another consultant ASAP
to provide information DWQ has requested. Company's owner very intent on not
discharing any wastewater (particularly for economic reasons). Also, employees
monitor pH routinely at another site and keep acid on hand in event of discharge;
amounts cited previously have been adequate in practice.
5/25: Spoke with Alissa Williams of URS Consulting (704-522-0330, cell 704-236-
8396), who is now working on the project. Client very concerned about delay in
beginning operation so they want to ensure everything we need is submitted. If they
demonstrate recycle system can contain 10-yr, 24-hour event, do they still need to
provide info. related to wastewater treatment? Advised that persistent rainfall could still
mean an overflow in rain that isn't a 10 yr storm, so we can't ignore possible wastewater
discharge even if the permit relieves permittee of monitoring requirement in 10 yr events.
Recommended that ifsystem is intended to be "non -discharge, "consider showing it can contain
25 year, 24-hrstorm (this is the threshold Non -Discharge (Aquifer Protection) uses far recycle
system), and if freeboard is reasonable for that event, would be comfortable in approving
permit —would demonstrate the site would discharge almost exclusively stormwater.
6/2: Call from A. Williams that company Fed-exed package to DENR.
6/3: Left message with A. Williams re: capacity of clean water tank (capacity before
overflowing?); whether there are settled solids volume allowances in the settling
tanks, and how slurry tank is tied into recycle system (does it pull solids from the
bottom of the settling tanks?) Also, should correct spreadsheet with 10 year, 24-hr
storm capacity calcs... carried 3088 cu. ft. through calculation for runoff, rather than
4965 cu. ft.
Also spoke with M. Houser re: above questions. CW tank 7200 cu. ft. is
capacity before overflow; solids volume negligible in settling tanks —company
installing Schwang agitators in first two primary settling tanks, and solids are
removed from the bottom to the slurry tank.
6/6: Spoke w/A. Williams re: corrections to spreadsheet. Received via e-mail 6/6.
Said the latest decision per M. Houser was that overflow pipe would not be used at
all (would maximize capacity of CW tank). Confirmed with M. Houser that
overflow pipe is plugged.

To: Bethany Georgoulias<[e-mail]>
Bethany,
As I understand the correspondence between you and the applicant, I think the
accomodation suggested for MacLeod is ok. Let's get Bradley's opinion, too.
Here's my perspective on the submittal, and the NCG14 COC for MacLeod.
a) The COC permits a stormwater discharge. OK
b) The COC permits the discharge of the process wastewaters, in accordance with the
permit limitations in NCG14. OK
c) The applicant's submittal did not demonstrate with calculations the ability of the
system to meet the wastewater effluent limitations in the permit, i.e.TSS, settleable
solids, and pH. UNDER CLEARER CIRCUMSTANCES, NOT OK, HOWEVER - --
d) However, and as an alternative, the DWQ determined that the applicant did
demonstate the following;
- With a significant safety factor built into his calculations, the applicant did
demonstrate that the system is designed to not discharge any wastewater during the
combined flows from 25-year storm and the currently contemplated production activity
flows. OK FOR TSS AND SETTLEABLES.
- The applicant asserts that muriatic acid will be used to control pH, by a
protocol already in place in other MacLeod sites, but not presented for our review in
this submittal. Given the holding capacity in excess of the 25-year storm, I think
this is OK FOR pH, too.
e) I think the ATC question is moot, since apparently the system is already built. I
see your note with the applicant's invitation to DWQ to come and see the facility, so
I conclude that it already exists. I would consider amending the COC transmittal
letter to remove the one sentence reference to the ATC requirement. The rest of that
paragraph does seem relevant to me.

This office has reviewed the subject erosion and sedimentation control plan and hereby
issues this letter of approval with modifications. A list of the modifications required is
attached. This approval is conditioned upon the incorporation or addition of these
modifications to the plan. If these modifications are not included in the plan and
implemented on the construction site; the site will be in violation of the Cabairus County
Soil Erosion and Sedimentation Control Ordinance (Sec. 17[I]) and the Sedimentation
Pollution Control Act of 1973. (G.S. 1 I3A-61rd1).
Please be advised that the Ordinance (Sec. 17[c]) and Title 15 NCAC 4B .0017(a)
requires that a copy of the approved erosion control plan be on file at the job site. You
should consider this letter to give the Notice required by Ordinance (Sec. 19) and G.S.
113A-61(d) of our right of periodic inspection to insure compliance with the approved
plan. Also, activities indicated on approved plans not completed within eighteen (1'8)
months of the date of approval shall be deemed null and void.
