Dale,
Please see the attached corrected Certificate of Coverage (COC) for NCG140427, Eagle Rock Concrete's Pristine Water
Drive site in Apex.I will mail a hard copy with the signature to Mr. Adam Loftin today, and I will send another signed
copy down to DWQ's Central Files. Because it is a correction, I have kept the original effective date.
The COC now includes only stormwater discharge and does not cover any wastewater discharges from this site. This
condition reflects the information presented in Eagle Concrete, LLC's N01 application. Groundwater standards in 15A
NCAC 02L and 02T regulations must also be met for recycle systems or any discharges to groundwater.
If you have any other questions or concerns, please let me know.
Thanks,

Hi Dale,
I'd included the process wastewater discharge on the COC because you all decided not to pursue the closed -loop recycle
system permit through APS. However, we can make the correction and include only stormwater on the NPDES permit.
This will mean that any process wastewaters that discharge, even if rarely, would be unauthorized. We recognize that's
an unlikely scenario because the system was designed to contain all wastewaters and the 25-year, 24-hour event. I will
be glad to correct the COC so it is consistent with the original application and with the other plant's COC.
I will do my best to send that correction in the next couple of days. I am working on our transition to a new Division and
electronic renewals for NCG21 the rest'of the week and will be on vacation all next week. If you don't hear from me
before then, I'll get to this as soon as I return.

Bethany,
To follow up my voicemail, please see the attached NCG14 permit issued for the Mt. Herman Road site. Both sites have
been designed in the same manner— separating stormwater from wastewater and storing/capturing all of the
wastewater from a 24 hr-25 yr storm event (per 15A NCAC 02L and 02T regulations) without discharging. So there is no
wastewater discharge to test, only stormwater discharge.
Please let us know what we need to do to reconcile the permits so they are in agreement.

Ryan and Dale,
The Raleigh Regional Office has given approval for us to proceed on this application for coverage under the NCG
permit. I am just requesting that you submit a revised copy of Sheet 4 of the plans (two copies) with the notation about
seeking a non -discharge recycle permit removed.
Instead of a separate permit from APS, DWQ will authorize any overflow that discharges from the recycle system in rare
instances under the COC for NCG14. The fact that the design incorporates the 25-year, 24 hour storm event and
freeboard of a non -discharging system sufficiently addresses the alternatives analysis of non -discharge options for the
wastewater that will be produced here. This is an important element of our review because this permit includes
wastewater discharges under the NPDES program.
If you have any questions, let me know. If we can get that revised plan sheet from you in the next week, I'll plan to issue
this COC next week.
Best regards,
Bethany

Subject: Eagle Rock Concrete, LLC - Pristine Water Drive Site
Hi Dale,
I am reviewing the NO1 application from Eagle Rock Concrete, LLC for the Pristine Water Drive site in Apex for coverage
under the NCG140000 Stormwater/Wastewater General Permit. I apologize for our delay in the review —we have been
down several staff positions for a while and were also very busy with our first round of electronic general permit
renewals in May and June.

I have contacted the Raleigh Regional Office for their concurrence with issuing a certificate of coverage for this site.
They may or may not conduct a site visit prior to giving their approval. I'll keep you updated on when I hear back from
their office.
Thank you for all the helpful detail on the plans. I thought they were well prepared. As I reviewed the NOI and plans, I
noticed that the company plans to build a closed -loop recycle system that will meet the 15A NCAC 2T .1000 rule criteria.
Sheet 4 of the plans also says "A Non -Discharge recycle permit will be sought from the NCDENR-DWQ." However, our
Aquifer Protection Section staff say they have not seen an application for a recycle system permit from this company
yet. Is the company still planning to pursue that?
Right now we would issue the COC for stormwater discharge only according to the application, but I want to be clear on
what the plan is.
Thanks for your help in clarifying it.

Hi Danny,
Attached is an NOI application from Eagle Rock Concrete, LLC for a new facility in Wake County (Apex). The company is
requesting coverage under NCG14 stormwater + wastewater general permit.
They will discharge stormwater to a UT to Middle Creek (Class QNSW) in the Neuse Basin. Operation was scheduled to
begin in June 2013, but I'm behind on these. I'm not sure of the status of the site. They have proposed a non -discharge
recycle system for all the process wastewater, including aggregate spray down. The NOI, and plans indicate they would
pursue a non -discharge permit, but Jon Risgaard in APS says they haven't seen anything from these guys. I will follow up
with the consultant about it today or tomorrow.
The plans were prepared by Withers & Ravenel (Dale Werenko, P.E.), and they're pretty decent. I'm attaching the N01,
and I'll forward a copy of the plan sheets to the RRO (to Dave Parnell's attention, if that's okay). Please let us know if
the Raleigh Regional Office have any concerns with issuing a COC for this site.
Normally we'll plan to issue the COC if we don't hear from you in 30 days, but we wait on NCG14 and NCG02 permits
until we have confirmation from the regional office. Thanks for your help with this one.
Thanks,
Bethany

Subject: RE: NOI for NCG140000 from Eagle Rock Concrete - Apex Site
Guys,
An update on this one. After the consultants at Withers & Ravenel looked into the permitting process for the recycle
system, some very typical things happened:
1) When investigating the application and process for an APS Recycle System Permit, they discovered there were
hardly any other concrete recycle systems permitted in the state and weren't sure how to start that process, or
why that might be. And then...
2) They read the 2T rules and thought their design met the deemed permitted requirements. The rules are not
very clear to explain "water used to removed concrete from equipment" is only drum washout water and does
not include washing the exterior of the vehicle (which vehicle washing exemption does, but that has to be
closed to precipitation inputs), and this trips a lot of people up in their interpretation. The aggregate pile spray
is also included (although, in this particular case it is settled drum washout water that drains back to the
system), and often people don't realize stockpile spray can't be an input either. [Basically, there are many
ready -mix plant "recycle systems" that really don't meet the permitted by rule option because they're capturing
several types of wastewaters in the recycle system].
3) We all agreed that while it is fantastic that they have designed a system to recycle water and hold the 25-year,
24-hour storm to prevent discharges from occurring (particularly from an engineering alternatives analysis
standpoint), it is just simpler to include authorization to discharge under the NPDES permit NCG14 in the very
rare event that it would ever overflow. I'm pretty sure this is APS's preference in most cases os well, but we
struggled with the authority to permit recycle systems under NCG14, and with our pending move to DEMLR in
August, �'m.even fuzzier on what: thisjrneons for0e NCG14 permit
So, we will just permit everything under the NCG14 permit. I'll have them resubmit revised plans so the notation that
they are pursuing a non -discharge permit is removed. Otherwise, 1 think everything looks okay, so I just need RRO's go
ahead whenever you all are ready.
Thanks,
Bethany

PROJECT SUMMARY
A RECYCLE FACILITY HAS BEEN DESIGNED TO CAPTURE THE 25YR-24HR STORM EVENT PLUS TRUCK WASHING AND DRUM
RINSE -OUT WITHOUT DISCHARGE TO SURFACE WATERS. THIS DESIGN CONSISTS OF ISOLATING THE INDUSTRIAL OPERATIONS
FROM THE NON -INDUSTRIAL AREAS. SURFACE STORMWATER/WASTEWATER IS COLLECTED VIA CONCRETE SURFACE FLUMES
AND DISCHARGES INTO A SERIES OF CONCRETE CHAMBERS DESIGNED TO SETTLE SEDIMENT AND PROVIDE STORAGE AS
REQUIRED TO MEET NCDWQ REQUIREMENTS. RECYCLE/PROCESS WATER FROM THE LAST CHAMBER WILL BE PUMPED
OUT AND RE -USED TO IRRIGATE AND HYDRATE AGGREGATE STORAGE AREAS AND RE -USED IN PROCESSED BATCH
CONCRETE.

Precipitation frequency (PF) estimates in This table are based on frequency analysis of partial duration series (PDS)_
Numbers in parenthesis are PF estimates at loner and upper bounds ofthe 9D% confidence interval. The Probability that precipitation frequency estimates (far a
given duration and average recurrence kftrval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maDdmum precipitation (PMP) estimates and may be higher than currently valid PMP values.

PROJECT SUMMARY
A RECYCLE FACILITY HAS BEEN DESIGNED TO CAPTURE THE 25YR-24HR STORM EVENT PLUS TRUCK WASHING AND DRUM
RINSE -OUT WITHOUT DISCHARGE TO SURFACE WATERS. THIS DESIGN CONSISTS OF ISOLATING THE INDUSTRIAL OPERATIONS
FROM THE NON -INDUSTRIAL AREAS. SURFACE STORMWATER/WASTEWATER IS COLLECTED VIA CONCRETE SURFACE FLUMES
AND DISCHARGES INTO A SERIES OF CONCRETE CHAMBERS DESIGNED TO SETTLE SEDIMENT AND PROVIDE STORAGE AS
REQUIRED TO MEET NCDWQ REQUIREMENTS. RECYCLE/PROCESS WATER FROM THE LAST CHAMBER WILL BE PUMPED
OUT AND RE -USED TO IRRIGATE AND HYDRATE AGGREGATE STORAGE AREAS AND RE -USED IN PROCESSED BATCH
CONCRETE. A NON -DISCHARGE RECYCLE PERMIT WILL BE SOUGHT FROM NCDENR-DWQ.

1. Structural drawings are intended to be used with architectural and PME drawings. Contractor is responsible for
coordinating such requirements into their shop drawings and work.
2. No opening shall be made in any structural member without written approval of the Structural -Engineer -of -Record.
3. No change in size or dimension of structural members shall be made without written approval of the
Structural -Engineer -of -Record.
4. Openings V-4" and less on a side are generally not shown on the structural drawings. Refer to architectural and PME
drawings for such openings.
5. The contractor is responsible for limiting the amount of construction loads applied to the structural framing. Construction
loads shall not exceed the design capacity of the framing at the time the loads are applied.
6. Fire proofing methods and materials for structural members are not shown on structural drawings, unless noted
otherwise. Refer to architectural drawings for fire proofing methods and materials.
7. Do not scale these drawings; use dimensions.
