Subject: NPDES Stormwater Permit Coverage Renewal COC #NCG140385
Dear Permittee:
For coverage under Stormwater General Permit NCG140000, the Division of Energy,
Mineral, and Land Resources (DEMLR) is forwarding herewith the reissued Certificate of
Coverage (COC). This permit is reissued pursuant to the requirements of North Carolina
General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007 (or as
subsequently amended.) A new Certificate of Coverage (COC) is included with this
letter.
You must print a copy of the new NCG140000 General Permit from our website here:
ermits f stormw erermits/npde:j.Odustrial-sw. In addition to the full permit, the 2017
print package on the website includes revised Discharge Monitoring Report (DMR) forms,
Annual Discharge Monitoring Report forms, and Qualitative Monitoring Report Forms.
The General Permit authorizes discharges of Stormwater and wastewater (if applicable),
and it specifies your obligations with respect to discharge controls, management,
monitoring, and record keeping. Please review the new permit to familiarize yourself with
all changes in the reissued permit. Significant changes to the General Permit are
outlined in the Technical Bulletin, which is also available on the website above. Your
facility has six months from receipt of the permit to update your Stormwater Pollution
Prevention Plan (SPPP) to reflect any new permit requirements.

How does the new General Permit affect Tier Status?
The first sample period of your permit begins August 1, 2017. Tier 3 actions in Part IV of
your permit are triggered by benchmark exceedances on four occasions beginning on the
effective date of this permit and do not count prior exceedances. Likewise, Tier 2 actions
are triggered by two consecutive benchmark exceedances beginning on the effective date
of this permit and do not count prior exceedances. However • if your facility is already in
Tier 2 (monitoring stormwater discharges monthly) or Tier 3, you must continue monthly
monitoring until relieved through conditions of the permit or by DEMLR staff approval.
When does electronic DMR reporting start?
We are setting up our database with final permit parameters and the outfalls that
permittees submitted on-line. All NCG14 Permittees will receive notification when our
eDMR system is ready for these permittees to register and begin reporting
monitoring data electronically. If you have any questions about the status, please
contact Bethany Georgoulias at [phone] or Robert Patterson at [phone]. If
you did not submit outfall information already, we have included a form for you to return
to us. (Note: NO FORM IS ATTACHED if we already have your outfall information.)
Your coverage under the General Permit is transferable only through the specific action of
DEMLR. This permit does not affect the legal requirements to obtain other permits which
may be required by the N.C. Department of Environmental Quality (DEQ), nor does it
relieve the permittee from responsibility for compliance with any other applicable federal,
state, or local law, rule, standard, ordinance, order, judgment, or decree.
If you have any questions regarding this permit package please contact the DEMLR
Stormwater Permitting Program at [phone].

We here at Hildreth Readymix are writing do to the Notice of
Violation. The reason that our company is not in compliance is
due to staff turnovers and some paperwork had been misplaced.
We have had several people to come and go throughout the
company and now that we are finally trying to get back on track.
Now since after the inspection I'm aware of the process that
must be taking to get Hildreth Readymix once again Compliant.
I know now to keep records of all papers, procedures, and
records. I now know that this have to be done and submitted
every quarter. We thank you for your patience and deeply
apologize for being late.

Inspection Summary
Multimedia inspection conducted by Mike Lawyer with FRO DEMLR and Joshua Hams with FRO DAQ to determine ,
compliance with the facility's stormwater and air permits. Met with Karl Hildreth at the plant, which was not operating at the
time of inspection. Observations were made of site conditions including waste concrete area, secondary containment area
for admixtures and recycle pit, which receives all process wastewater flow and stormwater, Mr. Hildreth claims that all flows
are contained in the recycle pit with the water pumped out as needed and used in the plant processes and there are no €
discharges off the property. Although there is a detailed site map for the facility, a Stormwater Pollution Prevention Plan per i
the conditions of the NCG140000 permit has still not been developed and there are no monitodrig records. C

Hildreth Redi-Mix #2
NPDES Permit Certificate of Coverage (COC) Number: NCG140385
Dear NPDES Permittee:
The NCG140000 General Permit expires on June 30, 2017. Our records indicate that your annual fees
are up to date; therefore, your coverage will be automatically renewed unless you submit a rescission
request for this permit. If you no longer need this permit, a rescission form can be found on our website
(http://Roo.gl/BcpDP4).
The new General Permit NCG140000 is scheduled for public notice in May 2017. At that time, the
proposed general permit will be available for public comment on our website. This notice process
should conclude in June, so that the new general permit can be issued effective July 1, 2017. Upon
issuance of the final general permit, your coverage will be renewed, and we will send you a new
Certificate of Coverage (COC) with the new effective and expiration dates.
In conjunction with this renewal process, two items require your action no later than May 31, 2017:
(1) You must review your permit contact information and notify us of any changes.
(2) You must submit outfall information on-line for this site in preparation for electronic data
monitoring report (eDMR) requirements.
Permit Contact Information
Please review the permit contact information enclosed. Ensure that Owner Affiliation and Permit
Contact are accurate, and that e-mail addresses are provided wherever possible. Your new COC will be
mailed to both of these contacts once the General Permit is renewed.

To update contact information for your permit: You may simply e-mail us changes to contact
information, unless there is a change to the Owner Affiliation. Because Owner Affiliation is the person
legally responsible for the permit, we require a hard copy of the signed Owner Affiliation Change Form
(enclosed) to make this change. (A change in company Name or Ownership requires a different form, so
please contact us if necessary.) Changes to other contacts can be e-mailed to Laura Alexander at
[e-mail].
Submitting Outfall Information for E-Reporting
The U.S. Environmental Protection Agency (EPA) finalized the National Pollutant Discharge Elimination
System (NPDES) Electronic Reporting Rule in December 2015. The rule requires NPDES regulated
facilities to report certain information electronically, instead of filing written paper reports. EPA is
phasing in the requirements of the rule over a 5-year period. The first phase requires regulated entities
to submit Data Monitoring Reports (DMRs) electronically starting on December 21, 2016,
While that deadline has passed, EPA is aware that NC is working on expanding the State's eDMR System
(currently available to NPDES Wastewater Permit -holders) to include Stormwater Program DMR
reporting. As soon as eDMR is available for your permit, we will notify you. In the meantime, we must
collect information about the discharge outfalls at your facility to prepare the system to flow data to
EPA as the new federal rule mandates.
To submit outfall information to DEQ: You must go to the following website and enter the
discharge outfall number, type of discharge, receiving water information, representative outfall status
information, and other details no later than May 31, 2017. The website will walk you through all steps.
The website is, https://deg.nc.gov/about/stormwater-program/stormwater-outfall-collection
The reissued general permit will include new electronic reporting requirements. For more information
on EPA's NPDES Electronic Reporting Rule, visit http://www2.epa,goy/compliance/final-national-

equipment traffic.
III. FACILITY/PROCESS DESCRIPTION: Hildreth Ready Mix #2 is a small concrete batch plant with
one cement silo and one fly ash silo. Cement and fly ash (if needed) is mixed with aggregate and Sand
(both stockpiled on site), which is mixed with water inside a cement truck. The cement and fly ash silos,
weigh hopper, and truck mix loading are all controlled by a central dust collector with bagfilters. Facility
is operated on an as -needed basis.

IV. INSPECTION SUMMARY: On 08 September 2016,1, Mike Lawyer with FRO DEMLR, and Josh
Harris with FRO bDAQ, arrived on situ to'conduct a Multimedia Inspection of Hildreth :Ready Mix #2. We
met with Avery Hildreth, Karl Hildreth's son, who was going to be operating the plant that day. When
asked about maintenance of the plant's bagfilters, Avery relayed that bags are repaired or replaced as
needed and that maintenance records should be at the Wadesboro plant office. Avery records production
amounts on a notepad. Avery said he was not aware of any complaints and that there have been no
changes to the facility. Facility has a propane tank for an office heater. We observed the loading of a
cement truck, which resulted in some fugitive dusting that dissipated quickly and did not cross the
property boundary. After loading, the truck was pulled forward and the exterior rinsed off before leaving
the plant.
Upon completing the inspection at Hildreth Ready Mix #2 in Richmond County, Mike Lawyer and Josh
Harris traveled to the Hildreth Ready Mix, LLC plant in Anson County to meet with Karl Hildreth and
conduct a Multimedia Inspection for the Anson County plant. When discussing the current process DAQ
is using regarding inspections for facilities that have rescinded their air permits, Mr. Hildreth stated that
he did not want to rescind his permit. Josh informed him that a letter requesting rescission had been
received and that the permit had already been rescinded. Copies of the original request. documents for
registration and rescission along with a copy of a signed letter for rescission that had been submitted to
DAQ were located within the facility's files. Mr. Hildreth reiterated that he did not want to rescind the
permit, that the letter was submitted by mistake and that he would like to have the permit reinstated.
V. EQUIPMENT ON SITE:
A. One weigh hopper and loadout operation;
B. One silo for cement storage, one silo for fly ash; and
C. Sand and aggregate stockpiles and handling equipment.

VI. APPLICABLE AIR QUALITY REGULATIONS:
A. 15A NCAC 2D .0515 - PARTICULATES FROM MISC. INDUSTRIAL PROCESSES -
Particulate emissions shall not exceed allowable emission rates as calculated by the following
equations:
E = 4.10 * (P) 0•6' for P < 30 tons/hr, or
E = 55 * (P) 40 for P >30 tons/hr
APPEARED IN COMPLIANCE: These calculations were made when the facility was permitted,
and the previous permit reviews indicated that that facility, when controls are properly maintained
and operated, would not exceed these limits. The facility's particulate emissions are controlled by
bagfilters. Each bagfilter appeared to have regular maintenance conducted, and there were no dust
accumulations near their exhaust points which would indicate an operational problem.
B. 15A NCAC 2D .0521- CONTROL OF VISIBLE EMISSIONS -Visible emissions shall not
exceed 20% opacity.
APPEARED IN COMPLIANCE: During loading of a cement truck, visible emissions were
observed, however nothing left the property boundary. DAQ has not received any recent complaints
pertaining to this facility.
C. 15A NCAC 2D .0535 - NOTIFICATION REQUIREMENT - Notify DAQ in the event of excess
emissions lasting longer than 4 hours resulting from malfunctions, breakdowns, or abnormal
conditions.
APPEARED IN COMPLIANCE: There are no indications of any excess emissions, which would
require a notification by the facility. There have been no recent complaints received by the facility or
DAQ.
D. 15A NCAC 2D .0540 - PARTICULATES FROM FUGITIVE DUST EMISSION SOURCES -
Fugitive dust emissions shall not contribute to substantive complaints, or excessive dust emissions
across the property boundary.
APPEARED IN COMPLIANCE: Observed one truck loadout, which did result in fugitive dusting,
however dust did not cross the property boundary. DAQ has not received any complaints regarding
this facility.
VII. NON-COMPLIANCE HISTORY SINCE 2010:
03/28/16 NOV issued for late annual reporting.
04/13/15 NOV issued for late annual reporting.
05/28/10 NOV issued for late annual reporting.
VIH. RISK MANAGEMENT (112r): This facility does not use or store any 112(r) subject materials above
threshold limits. Therefore, it is not required to maintain a written Risk Management Plan (RAP).

IX. CONCLUSION AND RECOMMENDATIONS:
Hildreth Ready Mix #2 appeared to be IN COMPLJANCE with applicable air quality regulations
on the date of inspection.

4. Please confirm a correct e-mail address for the Permit Contact. It is important! This is also
the e-mail address that will receive the electronic confirmation upon submittal.
5. After you submit the survey, the confirmation page will direct you to a map link. On that map,
you can search for your permit COC number to locate your facility. Click on the permit
location point and review the information in the pop-up box window. Please let us know if
anything is incorrect.
6. if you have any questions, or you wish to request a paper renewal package instead of receiving
your COC electronically next year, please contact us at [e-mail] or by calling
[phone].
We ask that you submit your renewal request no later than June 30, 2016. This will allow us to
communicate to all permittees ahead of final permit actions this year and next year.
What's next? Please check our website for updates (www.swpernlits.gov). We will also communicate
updates by e-mail, including when a revised General Permit is proposed for issuance. Next year, when
NC DEQ has renewed the General Permit and your new COC is ready, we will direct you to this same on-
line map to print the documents for your records. We will contact you by e-mail to let you know the new
permit is ready, or if you requested a paper package, we will mail you that package instead. We
encourage all permittees to provide an e-mail address for the most efficient communication time.
What about the new Electronic Reporting Requirements? This past December, the new NPDES
Electronic Reporting Rule became effective. This rule will phase in requirements for permittees to report
outfall monitoring data and other information over a five-year period. By December 2016, permittees
must begin submitting data monitoring reports (DMRs) electronically either to the state or to EPA
directly. NC DEMLR is working with the Division of Water Resources (DWR) to implement a system to
receive DMR data electronically from our permittees. In the coming months, we will need to collect
information about the outfall locations at your facility. As we develop a process for complying with the
new federal requirement, we will contact you with more guidance.
Discharge of stormwater without coverage under a valid stormwater NPDES permit constitutes a
violation of N.C. General Statute 143-215.1 and may result in the assessment of civil penalties of up to
$25,000 per day. Please follow these steps as soon as possible to ensure a timely renewal.
If you have questions, please contact Stormwater Permitting Program staff at [phone].

Re: DWQ Letter of December 23, 2008
NCG140378 — Hildreth Redi-Mix #2
Dear Ms. Jones:
As discussed with you Thursday, January 15, 2009, I am responding to your comments in
your letter of December 23, 2009.
Inadequate design Basis, Please address in your next submission:
✓ 1. As discussed January 15, 2009, Cell number 3 is not complete. Cell 3 will be
constructed as shown on sheet 4 of 4 of the attached plans.
u 2. As discussed January 15, 2009, Hildreth Redi-Mix will not be utilizing Anson County
pretreatment Department.
As discussed January 15, 2009, see sheet 1 of 4 bottom left side — Notes: Bullet 5..
Cell 1 is allowing 6" settlement, which will be pumped and carried to an approved
disposal area.
u 4. We have elected to use your 6.5 inches as addressed in you r letter of December 23,
2008.
v 5. We have elected your 6041 Cu. Ft. as address in your letter of December 23, 2008.
C67 As discussed January 15, 2009, we have elected to utilize your runoff depth of 6.5
J inches and your volume of 6041 Cu. Ft. As noted in No. 3 above, we are allowing 6
inches of settlement in cell 1. Our calculations show the storage capacity to be
exceeds.
Additionally, we found the following points were deficient in your application.
1. We discussed this issue in our conversation of January 15, 2009. It is possible that an
out fall previously noted as a ditch which is not on the Hildreth property. Out fill #2
is a' ditch {swell} which was existing at the time of the site visit. Out fall #2 will be
carried to basin 2 as noted on sheet 3 or 4.

2. Outfall #1 is the intermittent stream seen on the south end of the property. Storm
Water runoff from on site will be sampled before the onsite runoff reaches outfall #1.
3. As discussed January 15, 2009, sub -drain area t is located to the north, west and cast
of the bulk head for the aggregate stockpile. Sub -drain area 1 drains to the north-east
side of the site and will drain to basin 1 as noted on sheet 3 of 4. All washout
discharge will be carried to cell 1 and is part of the 75 gallons as noted on sheet 4 of
4, `Desian Calculation and Basis for Recycle System'.
4. A copy of the application to DEWR-Land Resources is submitted, herewith, as proof
that a submission was made for erosion and sediment control plan.
Transmitted, herewith, are 3 copies of submittals. There is no check in amount of 5100.00
enclosed.

On September 24, 2008 the NC Division of Water Quality's Stormwater Permitting Unit received your
third Notice of Intent (NOI) to be covered under North Carolina's General Permit NCG140000.
After review of the submitted material, we are requesting additional information for an NPDES General
Permit as your application is deficient in significant supporting information. Please ask your engineer to
contact me for an explanation of minimum submittal requirements.
Inadequate Design Basis. Please address these issues in your next submission:
1. In your initial submission cell 3 was stated as having 7' total depth from the bottom of the cell"
to the top of the wall. This gave a 6' total storage depth and a volume of 3795 W.
In the current submission you stated that the total depth = 7.7', with a 6.7' storage depth and a
total volume equal to 4238 ft3. This appears to be an additional storage volume of 442 ft3 (3312
gal).
As the cell is already constructed, please state how you will create this additional storage area,
or make your drawings and storage area consistent with the actual storage cells. Please also
reconcile this with storage of settled material within cells and a material clean -out schedule.
2. In your submission letter you state that you can carry the additional water to Anson County
Pretreatment Facility. However this letter only states that they have taken samples and that
Hildreth Ready Mix can apply.
If you intend on using the Anson County Pretreatment Department to dispose of wastewater,
please submit an approval letter stating that Anson County Pretreatment Department will

accept waste water from your facility, how much volume and for what time period (i.e. until
what date). Please also state if this acceptance has any conditions placed upon it.
3. Cell 1 calculations should include an additional storage depth for settled solids that would
accumulate in this cell. Please submit the depth has been allotted for additional storage of
settled solids in the bottom of cells and the procedure and schedule for cleaning out the cells.
✓ 4. Q (the runoff depth for the 25-year 24-hour storm) was submitted as 6.31". I calculated this to
be 6.5 inches using your submitted numbers and the NRCS runoff depth equation. Please
show how you calculated the number you submitted.
5. The Runoff Volume from the 25-year 24-hour storm, VR, was submitted as 5801 W.
I calculated a
v/ greater amount (6041 ft3) using the previous Q and the equation V=DA*Q. Please show how
your runoff volume Viz was calculated or reconcile your calculations with a larger number.
6. You calculated that the freeboard in your wastewater treatment system would be 1' after
receiving flow from a 25-year 24-hour storm when the pump was working fully. However, no
volume was allotted for solids accumulation in the cells. Additionally I found that a larger
storm volume of water would be sent to the cells (see Item 5).
Please provide additional volume for the cells than you have provided, matching the volumes
I have shown above, or clearly show the equations for the calculation of Q and VR. As stated
above, please demonstrate how additional volume will be added to these cells as they are
already constructed.
Additionally, we found the following points were deficient in your application. Please address these
points.
1. Outfalls have been more clearly marked in comparison to your previous submission, however,
we believe there is an additional/different outfall that is not shown on the site plans. Outfall 2
appears to be leaving the site in the Center -West of the lot. This follows the topography and
was seen in the site visit.
2. Outfall 1 appears to be the stream that runs on site. You may not perform in -stream sampling,
only from stormwater runoff on -site. The location for this outfall is up the bank from the
stream where stormwater leaves your property.
3. Additionally, sub -drainage area 1 appears to drain to the northeast side of the site. This
drainage area may contain sand and other materials and materials from the north end;
however, this is not mentioned nor clearly delineated. In your submission letter, Jimmy
Dennis states that "the runoff would go to basin L ..". There is no basin 1 at the site however.

Mr. Karl Hildreth

December 23, 2008
All cleanout materials and wastewater will be expected to be sent to the wastewater recycling
system.
4. You must include documentation that your Erosion and Sedimentation Control Plan
application to the NC Division of Land Resources was submitted. Stating on your application
that the site was previously graded is not sufficient. Please address this or your submission
will be considered to be deficient.
As before please submit originals and copies in the same manner as was previously requested.
Please submit the requested information by February 24, 2009. If you require additional time please

Dear Ms. Jones:
I take this opportunity to thank you and your, associates for the site visit of July 17, 2008. I will
answer each of the issues in your letter of June 17, 2008 and each of the bullets in your email of
July 18, 2008.
Issues of Letter of June 17, 2008 —
1 . Inadequate Design Basis:
a. Orifices shown on sheet 4 of 4 of the plans, number and size with elevations shown.
b. Calculations on plan sheet 4 of 4 of the plans indicate the capacity of the cells and the
required capacity for the 25 year storm as well as working capacity. Ct&1-Jt- ' °` tv
c. Plan sheet 4 of 4 indicates the correct National Weather Services estimate of the 25 year
`' 24 hour storm.
d. Any additional wastewater discharge not accounted for in the calculations can be taken
care of with the onsite recycle design and the fact that on site wastewater can be carried
t'' to the Anson County Wastewater Treatment Facility (Anson County Wastewater
Treatment is an option).
e. The material is shown on sheet 1 of 4 of plans
Wastewater will enter cell 1 (see sheet l or 4 of plans)
'J, !g. Contour elevations are shown on sheets 1, 2, & 3 with related elevations shown on sheet
4 of 4 of the plans
2. Inadequate Site Plan:
a. Outfalls shown on sheet 1 of 4 of plans (this is also bullet from July 17, 2008 meeting).
b. Adequate Stormwater topographic features.
A Please see sheets 1-3 of 4 of plans.
I[.' This area should only contain surface runoff and runoff from any y excessive
concrete washout waste after production. The runoff would go to basis, 1 as seen on
sheet 3 of 4 of plans.

III. There is a 4' x 6' reinforced concrete box culvert(RCBC) located at this location
and is shown on the plans.
c. Topographic elevations and contours shown on the plans. See sheets 1-4 of plans for
contours and elevations to determine stormwater flow.
d. The vertical and cross slope of sub -drain area 5 does not justify curb around the area. An
asphalt/concrete-berm was added to the west and an asphalt berm was added to the west
of the cells to direct flow to cell no. 1.
e. Sediment basins as shown on sheet 3 of 4 will be utilized in —definitely. The basins will
7 naturally develop into minor wet lands if left in place. 7 A ,
3. Incomplete Submital:
a. Three copies of the following are submitted herewith.
I. Plan sheets I — 4 (3 sets)

On March 18, 2008 the NC Division of Water Quality's Stormwater Permitting Unit received your
second Notice of Intent (NOI) to be covered under North Carolina's General Permit NCG14O000.
After review of the submitted material, we are returning your request for an NPDkS General'
Permit as your" application is deficient in significant supporting information. Please ask your
engineer to contact me for an explanation of minimum submittal requirements.
The submittal is deficient in the following particulars:
1. Inadequate Design Basis: You have applied for a permit to discharge stormwater and for an
Authorization to Construct treatment or recycle facilities. North Carolina rules require DWQ
to conduct an engineering review of your application.
In reviewing any permit we evaluate whether or not engineering calculatiins will predict
compliance. The following issues were present:
a. No orifices were shown (nor'their elevation) leading from cell 2 to 3. Without this
complete information we cannot accurately evaluate these plans.-. -
b. The design must show that.the recycle system will hold water from your industrial
processes, plus the 25-year 24-hour storm for your location, plus 1 foot of additional
Freeboard. The submitted design appears to take into account the minimum amount
of water that may be present if your recycle system is working at that time. Design
operating conditions'should be calculated as a conservative'estimate of the maximum
level of water present when operating at any time.: We believe this system cannot
reasonably be expected to hold the water level shown in your submission at all times.
c. We found a discrepancy.between the NOAA, National Weather Service's estimate of
the 25-year, 24-hour storm depth and this depth you reported for your site. This
.change significantly affects the amount of water needed to be held by the storage
system. Please reference the NOAA's website to fihd the most current rain depths
and intensities: http://hdsc.;nws.noaa.gov/hdsc/pfds/orb/nc—pfds.html.

d. In your site plans you did not account for an additional wastewater discharge: the
wash water from washing under the cement silo and the course of its discharge.
e. You do not specify the material (i.e., cement or other?) for the base of wastewater
cell holding tanks 1 through 3.
f. Cell 1 calculations should include an additional storage depth for settled solids that
would accumulate in this cell.
g. It is unclear how wash water is entering the system. We were concerned about
routes of water entry - specifically with the orifice dimensions in cell 1 and possible
water entry through ramps. These ramps appear to allow water to enter the system
into cells 1 and 2; however, this point is unclear in your submission.
h. The relationship of the treatment system's elevation to the surrounding topography is
unclear as you have neither shown any topographical elevations in your plans nor
have you shown the relationship of the cells elevation to the surrounding area.
Additionally, we found the following points were deficient in your application:
2. inadequate Site Plan:
a. Outfalls are neither clearly shown on plans, nor are they numbered.
b. Adequate stormwater topographical features are not properly shown, nor how those
features affect drainage.
i. There are no topographical features shown delineating sub -drainage areas (for
instance sub -drainage areas 2 and 3), such as break-points at the ends of bulk
heads.and a possible berm at the northwest side of the site.
ii. Additionally, sub -drainage area 1 appears to drain to the northeast side of the
site. This drainage area may contain sand and other materials and materials
from the north end; however, this is not mentioned nor clearly delineated.
iii. It appears there may be a discharge off the south end of the site. We could
-see no outlet from this "undisturbed" area. Please indicate if there is a pipe
flowing beneath the highway or another type of outfall.
c. No topographical elevation levels are present on site drawings. These levels are
needed to determine stormwater flow from the site.
d. In your site plans'we could not find a curb or other method delineating the concrete
sub -drainage area - SD# 5. In order to -delineate the drainage area this curb should
surround the entire area.
e. Please indicate if sediment basins are intended to be permanent structures. You do
not include a permanent stormwater drainage map (only a hybrid between EMIS and
final stormwater plans).
3. Incomplete Submittal:
a. You must include three copies of all materials for submittal. In your second
application letter and plans you referenced information from your,first submittal.
This information did not appear in your second: application plan set or calculations.
.-You must submit all site data on plans to be considered for approval as one complete
package. We do not keep previously submitted materials.
b. _You must include documentation that your Erosion and Sedimentation Control Plan
application to the NC Division of land Resources was submitted. Stating on your
application that the site was previously graded is not sufficient. It appears that

Jennifer,
In your absence today I took a call from Jimmy Dennis, the engineer that we met on
Hildreth's site last year. He called with questions on your recent add -info letter.
I advised that I had conferred with you on the letter, but that I couldn't speak for
you as to the sufficiency of any potential responses from him/Hildreth. I did not
have the letter in hand as we spoke. He continued our conversation, anyway, on these
subtopics:
a) I•advised that we have never been receptive to the proposal that the wastewater
from a ready -mix concrete site be tested, treated if necessary, and manually released
on a batch basis as a regular operating mode. We have uniformly advised others that
an automated pH control system is a necessary degree of reliability in the
circumstances that prevail at most ready -mix facilities.
b) He reported that Mr. Hildreth has already built the third basin, which he believed
you were not aware of at the time of the add -info letter.
c) He also suggested that they would install a Faircloth skimmer (a floating discharge
device, typically with a constant discharge) in th—e -bird chamber, with discharge to
the receiving water. We did not get into the specifics of how the constant discharge
device reconciled with his report that they would only discharge wastewater in the
event of a 25-year storm. (Valved, perhaps?) I understood from his comments that the
volume in the third chamber would be used as recycled mix water.
d) He reported that Mr. Hildreth has given up on the option of transporting the'
wastewater to a local POTW due to the costs involved. His response to your add -info
request about this option will be to the same effect.
e) I clarified-the-perm9:.t_requirement-tr t=the-pe—rmi,tt ee_is oob.li�ated"to-sampleaeve,ry
stormwate o tfall,3and eve ky, w s.tewa.ter ou.t.ftw' ce> -per-yearo. -I relayed our
provisions for granting representative outfall status for stormwater-only outfalls.
f) He asked about my on -site comments about wasting excess concrete in the flat area
in the northeast corner of the site. My comments on that topic on that day apparently
led to a misunderstanding. I apologized to him for my faulty communications, and I
clarified that I didn't specifically remember what I said, but that I hoped what I
said was:
- 1. Many producers waste small amounts of concrete to the ground, and reclaim it as
fill materiai�or�agg•r'eg�te; or=wast'e=it=into=forms•; lace=highway=divider=£oxms;,:;fs�x
sybsequent=use-ful purposes.
2. Any flow generated from the wet=dumped=concr-ete=woud-d=be-a=wa's-tewa.ter, and would
have to be-t-rea.ted_as_ c�a �h.before-di's'chzrge�f-r.om.the;sdste—Ihe' drum-washout-wa-s•tewa,ter
is .t;ypieally--the-st'ror�g wastewate (ham° h pH) generated'on-s-,ibte. Any flow from the
dried concrete would presumably be a stormwater.
- 3. Specifically, it is unlikely that,_we would conclude that any such runoff from the
wet material had been adequately treated to within permit limits by simply ru g it
through the sedimentation basin propose or e nor eas corner o -the site. It
would have to be treated for pH, too. It does not appear to make sense for Hildreth
to buy two pH correction units. He should encourage his client to just get the one
unit, adjacent to the 3 wastewater, treatment chambers. Hildreth needs to develop
operating procedures that will insure that any to -the -ground wasting of excess
concrete will not result in an inadequately treated wastewater discharge.

in the site visit.
b. Adequate stormwater topographical features are not property shown, nor how those
features affect drainage.
There are no topographical features shown delineating sub -drainage areas (for
instance sub -drainage areas 2 and 3), such as break-points at the ends of bulk
heads and a possible berm at the northwest side of the site.

4. They also do not show any runoff coming off their cement roadway
even though it must be coming off there.
5. Outfall 2 looks diverted into outfall 1 which is not the case - it leaves
via a stream to the SW.
6. Outfatt 1 may have sand and other materials - this appears it may run
off down the slope if there was a large storm.
ii. Additionally, sub -drainage area 1 appears to drain to the northeast side of the
site. This drainage area may contain sand and other materials and materials
from the north end; however, this is not mentioned nor clearly delineated.
1. In his return letter. Jimmv Dennis states that "the runoff would eo to
basin 1...". There is no basin 1 at the site however.
iii. It appears there may be a discharge off the south end of the site. We could
see no outlet from this "undisturbed" area. Please indicate if there is a pipe
flowing beneath the highway or another type of outfall.
1. OK
c. No topographical elevation levels are present on site drawings. These levels are
needed to determine stormwater flow from the site.
1. Very minimal - only 2 shown as every 20 vertical feet but technically present
so O.K.
In your site plans we could not find a curb or other method delineating the concrete
sub -drainage area - SD# S. In order to delineate the drainage area this curb should
surround the entire area.
I. OK - submission states that the asphalt berm was added. No curb however
but a berm is ok.
ii. Ask Mike to Check this at the site.
Please indicate if sediment basins are intended to be permanent structures. You do
not include a permanent stormwater drainage map (only a hybrid between EHM and
final stormwater plans).
I. Their submission states "sediment basins... will be utilized in definitely. The
basins will naturally develop into minor wetlands if left in place".
ii. They are not currently present and not constructed.
iii. Thev will not likely develop into anv kind of wetland as such.
iv. Address in resubmittat letter
Incomplete Submittal:
a. You must include three copies of all materials for submittal. In your second
application letter and plans you referenced information from your first submittal.
This information did not appear in your second application plan set or calculations.
You must submit all site data on plans to be considered for approvat as one complete
package. We do not keep previously submitted materials.
b. You must include documentation that your Erosion and Sedimentation Control Plan
Application to the NC Division of Land Resources was submitted. Stating on your
application that the site was previously graded is not sufficient. It appears that
Erosion and Sedimentation Control Basins will need to be created, and your site may
need to be additional grading and stormwater measures installed.
Because of the above deficiencies, we are returning your application submitted as such.

This is the same site that we all met at back in the summer right? And not Mr. Hildreth's other site in Anson County?
Has he submitted an NCI for the Anson County facility yet? We issued an NOV to him for operating the Anson County
site without appropriate permit coverage. You should have a copy of the NOV as well as further correspondence from us
to him concerning his response to the NOV. I've attached a scanned copy of the last response we received, which is
from his consultant. I don't know if we can hold off on issuing coverage for the Richmond County site until he has
submitted for coverage of the Anson County site, but that's what I would recommend. Otherwise, if the engineering
looks good to you, then proceed with issuance_

1_ Hi Mike,
We've received an NOI from Hildreth Ready Mix #2 for their facility in Rockingham (Richmond County) for coverage
of their ready mix facility under. The site discharges stormwater into a UT to Hitchcock Creek (C). They are
stating that they are designing for the 25-year 24-hour storm so they will not have a WI discharge. The NOI is
attached.
Does the Fayetteville Regional Office have any concerns about issuing this facility a COC for this general

I have written an add info letter and attached it. I will send you the complete information by mail when it comes

Hi Jimmy,
Thank you for taking the time to show us around your site yesterday. To follow up I wanted to recap some
of the points we talked about.
• Please show all aggregate piles on site.
• Please show all outfalls - we saw on one the West side, one to the North, and Ken said he saw one
that was your stream on the South side. There may be others that we did not see. You may show
outfalls with an arrow and numbering.
• You may put in stormwater treatment basins as you have shown on page 3 of your previous site plan
submission. These are not required for the permit but would be an additional stormwater protection.
• Mr. Hildreth must direct all wastewater to his treatment cells and preferably this would be done at the
cells when possible - this includes any water from washing out trucks, washing off trucks, misting
trucks, and any water that has contacted aggregate piles if you are irrigating them.
• Please show that there is a dirt basin but you will be taking it out.
• Please show your new calculations and sizing of cell 3 for the 25-year 24-hour storm.
• Please show any pump and haul - as we discussed on site you will need to provide a letter for this.
• Please address the waste water running off from the misting/cement loading area - not all of this
water appears to be capture by the cells.
• Please show how wastewater will be moving from cell to cell, show the orifices and describe any
barriers diverting wastewater from the outside to cell 1 - all in detail.
It may be beneficial to either meet with us or have a conference call with us before you submit plans.
Please let me know if you would like to do this.
The text of the permit can be found at: http://h2o.enr.state.nc.us/su/documents/NCG14000O-2004 OOO.pdf
and our technical bulletin can be found at: httpalh2o.enr.state.nc.us/su/documents/NCG14 Cover 2006.pdf

One other quick note. You'll notice in the follow-up letter that I sent to Mr.
Ilildreth in 106 that he was given a time frame of 30 daysto.submit the NOI to avoid
the issuance of an NOV. I must admit that I had lost track of this issue until
recently and neglected to issue an NOV after the 30 day allotment. It has now
obviously been 2 years since then and I have no excuses for not: following through. My
apologies all around.

All,
Our office received a complaint today concerning Mr. Hildreth's other concrete
plant in Wadesboro, Anson County. This one he has been operating for at least a
couple of years without appropriate permit coverage. His business used to invoive
making concrete septic tanks and he had coverage under the NCGC70000 permit for
concrete products. He switched over to redi--mix sometime in 2006 and I had received
a complaint back then concerning runoff into the roadside ditch, r had met: with Mr.
Hildreth and expressed the need for him to rescind coverage under NCG07 and obtain
coverage under NCG19. I even followed up with a letter by Certified Mail including
a copy of the NOI that he signed for. on 6-7-06, which I have attached for your
reference. I brought this issue back up during our recent site visit-- to his new
plant in Richmond County to which he replied that he wanted to get permitting
settled for the new plant prior to dealing with the existing plant.in Anson County.
I'm not sure how we want to handle the issues with the new plant, considering that
we have not necessarily observed any runoff and he claims that the new plant is not
operating yet, but I feel we should definitely address the Anson County plant with
an NOV/keco mendati.orn for Enforcement- for constructing a plant wI.thout submitting
an NOI/ATC as well as discharging wastewater and stormwater without a permit.
The complaint we received today is from a Mr. Shannon Hildreth (relative of some
kind) who laves near the plant in Anson County. His complaints involve the
following: 1) an above ground fuel tank withoui any containment that is leaking
fuel onto the ground near a cemetery (could be addressed by the Inactive Hazardous
Sites Branch, which 1 understand now deals with any and all releases or spills of
petroleum products onto the ground), runoff from washing of trucks entering a basin
of some kind (earthen pit from what I remember) that then goes into a city pond
from where Anson County gets some of its drinking water, and house demolition
debris being dumped behind the owner,'s residence, which is on the same site as the
fuel tank and concrete plant (probably addressed by the Solid Waste Section). After
speaking to the complainant, he also expressed that runoff has entered another
neighbor's fishing pond leaving the surface of the pond a' gray color.
I know that the regional offices typically issue NOVs for such activities, but I
would like to get some assistance from the SPO and NPSACOU on the appropriate
language to put into the NOV. Any thoughts, comments, suggestions, and/or
assistance would be greatly appreciated.

Dear Mr. Hildreth:
On September 24, 2008 the NC Division of Water Quality's Stormwater Permitting Unit received your
third Notice of Intent (NOI) to be covered under North Carolina's General Permit NCG140000.
After review of the submitted material, we are requesting additional information for an NPDES General
Permit as your application is deficient in significant supporting information. Please ask your engineer to
contact me for an explanation of minimum submittal requirements.
Inadequate Design Basis. Please address these issues in your next submission:
1. In your initial submission cell 3 was stated as having 7' total depth from the bottom of the cell
to the top of the wall. This gave a 6' total storage depth and a volume of 3795 W.
In the current submission you stated that the total depth = 77, with a 6.7' storage depth and a
total volume equal to 4238 W. This appears to be an additional storage volume of 442 ft3 (3312
gal).
As the cell is already constructed, please state how you will create this additional storage area,
or make your drawings and storage area consistent with the actual storage cells. Please also
reconcile this with storage of settled material within cells and a material clean -out schedule.
2. In your submission letter you state that you can carry the additional water to Anson County
Pretreatment Facility. However this letter only states that they have taken samples and that
Hildreth Ready Mix can apply.
If you intend on using the Anson County Pretreatment Department to dispose of wastewater,
please submit an approval letter stating that Anson County Pretreatment Department will

accept waste water from your facility, how much volume and for what time period (i.e. until
what date). Please also state if this acceptance has any conditions placed upon it.
3. Cell 1 calculations should include an additional storage depth for settled solids that would
accumulate in this cell. Please submit the depth has been allotted for additional storage of
settled solids in the bottom of cells and the procedure and schedule for cleaning out the cells.
4. Q (the runoff depth.for the 25-year 24-hour storm) was submitted as 6.31". I calculated this to
be 6.5 inches using your submitted numbers and the NRCS runoff depth equation. Please
show how you calculated the number you submitted.
5. The Runoff Volume from the 25-year 24-hour storm, VR, was submitted as 5801 ft3.
I calculated a
greater amount (6041 ft3)using the previous Q and the equation V=DA*Q. Please show how
your runoff volume VR was calculated or reconcile your calculations with a larger number.
6. You calculated that the freeboard in your wastewater treatment system would be 1' after
receiving flow from a 25-year 24-hour storm when the pump was working fully. However, no
volume was allotted for solids accumulation in the cells. Additionally I found that a larger
storm volume of water would be sent to the cells (see Item 5).
Please provide additional volume for the cells than you have provided, matching the volumes
I have shown above, or clearly show the equations for the calculation of Q and VR. As stated
above, please demonstrate how additional volume will be added to these cells as they are
already constructed.
Additionally, we found the following points were deficient in your application. Please address these
points.
1. Outfalls have been more clearly marked in comparison to your previous submission, however,
we believe there is an additional/different outfall that is not shown on the site plans. Outfall 2
appears to be leaving the site in the Center -West of the lot. This follows the topography and
was seen in the site visit.
2. Outfall 1 appears to be the stream that runs on site. You may not perform in -stream sampling,
only from stormwater runoff on -site. The location for this outfall is up the bank from the
stream where stormwater leaves your property.
3. Additionally, sub -drainage area 1 appears to drain to the northeast side of the site. This
drainage area may contain sand and other materials and materials from the north end;
however, this is not mentioned nor clearly delineated. In your submission letter, Jimmy
Dem-tis states that "the runoff would go to basin 1...". There is no basin 1 at the sitehowever.

4. You must include documentation that your Erosion and Sedimentation Control Plan
application to the NC Division of Land Resources was submitted. Stating on your application
that the site was previously graded is not sufficient. Please address this or your submission
will be considered to be deficient.
As before please submit originals and copies in the same manner as was previously requested.

There are a few points of clarification which 1 need to be able to complete the application.
1.Inadequate Design Basis:
1) In b. of your letter, last sentence you state "We believe this system cannot reasonably be expected
to hold the water level shown in your submission at all times." I would like to have a better
understanding of the meaning. We have tried to show that the overall storage wi11 hold the 25
year/24hour event and that the cells will be able to hold in addition the waste water from the washouts
and wash off as well as the one foot freeboard. The Pump activates as soon as there is 0.5 foot water in
cell 3 and all the preliminary storage in cells 1 and 3 is accounted for.
2) In c. when I. go to the'NWS site I find P=6.59 and I use Q=6.31 for the 25 yr./24:hour event.
Would you confirm this or advise the Q you may use.
3) In f. you ask for additional storage depth for settled solids. Cell 1 allows for 1:58 feet, deep of
storage being wastewater or solids, the transmittal letter of March 11,2008 addresses the solids to be
pumped out when ,6 inches of settlement has accumulated (see 4.-d of letter.) Do .you want this stated on
the plans? Unle.ss'the pump stops working I see no reason why the cells can't.hold the quantity. from all
operations and the:25yr/24hr. event. ;
3. Incomplete Submittal:
1) In b. you state "It appears that Erosion and Sedimentation Control Basins will need to be created,
and your site may
need to be additional grading and stormwater measures installed. -Please clarify this statement. I
think we would want
grading to a minimum"and to keep ground disturbance to a minimum.
Your assistance will be greatly appreciated. If you like, we would be most happy to have an on site
meeting.

Dear Mr. Hildreth:
Coleen H. Sullins Director
Division of Water Quality
On March 18, 2008 the NC Division of Water -Quality's Stormwaterr-Permitting Unit received your
second Notice of Intent (NOI) to be covered under North Carolina's General Permit NCG140000.
After review of the submitted material, we are returning your request for an NPDES General
Permit as. your application is deficient insignificant supporting information. Please ask your
engineer to contact me for an explanation of minimum submittal requirements.
The submittal is deficient in the following particulars:
1. Inadequate Design Basis: You have applied for a permit to discharge stormwater-and for an
Authorization to Construct treatment or recycle facilities. 'North Carolina rules require DWQ
to conduct an engineering review of your application.
In reviewing any permit we evaluate whether or not engineering calculations will predict
compliance. The following issues were present:
a. No orifices were shown (nor their elevation) leading from cell 2 to 3. Without this'
complete information we cannot accurately evaluate these plans.
b. The design must show that -the recycle system will hold water from your industrial
processes, plus the 25-year 24-hour storm for. your location, plus 9 foot of additional
freeboard. The submitted design appears to take into account the minimum amount
of water that may be present if your recycle system is working at that time. Design
operating conditions should be calculated, as a conservative estimate of the maximum
level of water present when operating at any. time. We believe this system cannot
reasonably be expected to hold the water level shown in your submission at all times.
c. We found a discrepancy between the NOAA,,,National Weather Service's estimate of
the 25-year, 24-hour storm depth and. this depth you reported for your site. This
change significantly affects the amount of water needed to be held by the storage
system. Please reference the NOAA's website to find the most current rain depths
and intensities: http://hdsc.nws.noaa.gov/hdsc/pfds/orb/nc_pfds.htmi.

d. In your site plans you did not account for an additional wastewater discharge: the
wash water from washing under the cement silo and the course of its discharge.
e. You do not specify the material (i.e., cement or other?) for the base of wastewater
cell holding tanks 1 through 3.
f. Cell 1 calculations should include an additional storage depth for settled solids that
would accumulate in this cell.
g. It is unclear how wash water is entering the system. We were concerned about
routes of water entry - specifically with the orifice dimensions in cell 1 and possible
water entry through ramps. These ramps appear to allow water to enter the system
into cells 1 and 2; however, this point is unclear in your submission.
h. The relationship of the treatment system's elevation to the surrounding topography is
unclear as you have neither shown any topographical elevations in your plans nor
have you shown the relationship of the cells elevation to the surrounding area.
Additionally, we found the following points were deficient in your application:
2, inadequate Site Plan:
a. OutfaRs are, neither clearly shown on.plans, nor are they numbered.
b. Adequate stormwater topographical,features are not properly shown, nor how those
features affect drainage. 7.1
i. There are no topographical features shown delineating sub -drainage areas (for
instance sub -drainage areas ._21and 3), such as break-points at the ends of bulk
heads and a possible berm at.the northwest side of the site.
ii. Additionally, sub -drainage aea 1 appears to drain to the northeast side of the
site. This drainage area may contain sand and other materials and materials
from the north end; however, this is not mentioned nor clearly delineated.
iii. It appears there may be a discharge off the south end of the site. We could
see no outlet from this "undfsturbed" area. Please indicate if there is a pipe
flowing beneath the highway, or_another type of outfall.
c. No topographical elevation levels4re present on site drawings. These levels are
needed to determine stormwater flow from the site.
d. In your site plans we could not find -a curb or other method delineating the concrete
sub -drainage area - SD# 5. In order to -delineate the drainage area this curb should
surround the entire area.
e. Please indicate if sediment basins are intended to be permanent structures. You do
not include a permanent stormwater drainage map (only a hybrid between EH&S and
final stormwater plans).
3. Incomplete Submittal:
a. You must include three copies of sil materials for submittal. In your second
application letter and plans you referenced information from your.first submittal.
This information did not appear in your second application plan set or calculations.
-You must submit all site data on plans to be considered for approval as one complete
package.. We do not keep previously submitted materials.
b. You must include documentation that your Erosion and Sedimentation Control Plan

Dear Mr. Hildreth:

Division of Water Quality

Subject: Second Return of NCG140378
Application Return #1185
Hildreth Redi-Mix #2
518 West U.S. Highway 74
Rockingham, NC 28379
Richmond County
On March 18, 2008 the NC Division of Water Quality's Stormwater Permitting Unit received your
second Notice of Intent (NOI) to be covered under North Carolina's General Permit NCG140000.
After review of the submitted material, we are returning your request for an NPDES General
Permit as your application is deficient in significant supporting information. Please ask your
engineer to contact me for an explanation of minimum submittal requirements.
The submittal is deficient in the following particulars:
1. inadequate Design Basis: You have applied for a permit to discharge stormwater and for an
Authorization to Construct treatment or recycle facilities. North Carolina rules require DWQ
to conduct an engineering review of your application.
In reviewing any permit we evaluate whether or not engineering calculations will predict
compliance. The following issues were present:
a. No orifices were shown (nor their elevation) leading from cell 2 to 3. Without this
complete information we cannot accurately evaluate these plans.
b. The design must show that the recycle system will hold water from your industrial
processes, plus the 25-year 24-hour storm for your location, plus 1 foot of additional
—freeboard. The submitted design appears to take into account the minimum amount
of water that may be present if your recycle system is working at that time. Design
operating conditions should be calculated as a conservative estimate of the maximum
level of water present when operating at any time. We believe this system cannot
reasonably be expected to hold the water level shown in your submission at all times.
c. We found a discrepancy between the NOAA, National Weather Service's estimate of
the 25-year., 24-hour storm depth and this depth you reported for your site. This
change significantly affects the amount of water needed to be held by the storage
system. Please reference the NOAA's website to find the most current rain depths
and intensities: http://hdsc.nws.noaa.gov/hdsc/pfds/orb/nc—pfds.htmi.

Mr. Karl Hildreth
Hildreth Redi-Mix #2.

d. In your site plans you did not account for an additional wastewater discharge: the
wash water from washing under the cement silo and the course of its discharge.
e. You do not specify the material (i.e., cement or other?) for the base of wastewater
cell holding tanks 1 through 3.
f. Cell 1 calculations should include an additional storage depth for settled solids that
would accumulate in this cell.
g. It is unclear how wash water is entering the system. We were concerned about
routes of water entry - specifically with the orifice dimensions in cell 1 and possible
water entry through ramps. These ramps appear to allow water to enter the system
into cells 1 and 2; however, this point is unclear in your submission.
h. The relationship of the treatment system's elevation to the surrounding topography is
unclear as you have neither shown any topographical elevations in your plans nor
have you shown the relationship of the cells elevation to the surrounding area.
Additionally, we found the following points were deficient in your application:
2. Inadequate Site Plan:
a. Outfalls are neither clearly shown on plans, nor are they numbered.
b. Adequate stormwater topographical features are not properly shown, nor how those
features affect drainage.
i. There are no topographical features shown delineating sub -drainage areas (for
instance sub -drainage areas 2 and 3), such as break-points at the ends of bulk
heads and a possible berm at the northwest side of the site. • _ ..
ii. Additionally, sub -drainage area 1 appears to drain to the northeast side of the
site. This drainage area may contain sand and other materials.and materials
from the north end; however, this is not mentioned nor clearly delineated.
iii. It appears there may be a discharge off the south end of the site. We could
see no outlet from this "undisturbed" area. Please indicate if there is a pipe
flowing beneath the highway or another type of outfall.
c. No topographical elevation levels are present on site drawings. These levels are
needed to determine stormwater flow from the site.
d. In your site plans we could not find a curb or other method delineating the concrete
sub -drainage area - SD# 5. In order to delineate the drainage area this curb should
surround the entire area.
e. Please indicate if sediment basins are intended to be permanent structures. You do
not include a permanent stormwater drainage map (only a hybrid between EH&S and
final stormwater plans).
3. Incomplete Submittal:
a. You must include three copies of all materials for submittal. In your second
application letter and plans you referenced information from your.first submittal.
This information did not appear in your second application plan set or calculations.
You must submit all site data on plans to be considered for approval as one complete
package. We do not keep previously submitted materials.
b. You must include documentation that your Erosion and Sedimentation Control Plan
application to the NC Division of Land Resources was submitted. Stating on your
application that the site was previously graded is not sufficient. It appears that

Mr. Karl Hildreth`
'4;, ildreth Redi-Mix #2.

Erosion and Sedimentation Control Basins will need to be created; and your site may
..need to be additional grading and stormwater measures installed.
Because of the above deficiencies, we -are returning your application submitted as such.
If you have any questions or concerns regarding your application or these forms, please contact
me at [phone] ext. 591.

NCG 140000 Application—
Hildreth Redi-Mix #2
Application Return (Return #1152)
Richmond County
Dear Mr, Hildreth:
On August 30, 2007, 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 NCG 140000. 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.
1. Site Plan: The site plan provided was not sufficient. Please provide a site plan with
better detail. For example, the following information is not clear on the plan:
a. Drainage areas for portions of the site outside the recycle system (these should be
delineated).
b. Exactly where the Swale up -slope of the recycle basin begins and ends.
c. What part of the drainage area to the recycle system is concrete and what .is not.
d. Which areas of the plant site are paved or gravel (impervious) and which are not.
e. What the notation above the silo says, and what the structure next to the silo is.
f. Stormwater and wastewater discharge points from the property.
The site map should very clearly outline drainage areas, stormwater and/or wastewater
discharge points that correspond to those drainage areas, treatment structures, runoff
conveyance structures, material storage areas, impervious areas, and site property lines.
2. Plans and Specifications: Diagrams and specifications were included for the pump and
recycle basin; however, no.details about the temporary storage basin, piping from the
recycle system to the temporary storage basin, or how the water would be recycled back
to the plant were included with the application. Please provide more detailed plans and
specifications about these treatment components.

3. Aggregate Pile Irrigation: The application indicated no discharges from wetting of raw
material stockpiles would occur at this site (Question 14.); however, the site map shows a
storage basin "to spray on sand and aggregate piles." The stockpile area is situated
behind a retaining wall and does not drain into the recycle system. Any drainage from
this area is considered a wastewater discharge, and if that water is not routed into the
recycle system, it must be treated to meet effluent limits in NCG140000. Please (1)
explain how the water will be treated, and/or provide calculations or other information to
demonstrate that the discharge will meet permit effluent limits when discharged from the
property, or (2) redesign the recycle system to capture and treat this water, and revise the
site plan accordingly.
4. Design Calculations and Basis for Recycle System
a. There is no water balance calculation provided for the recycle system. What
amount of water will go into the basin from drum washouts (and other inputs),
and what are the assumptions daily input is based on? What amount of water will
be drawn out for concrete manufacture and temporary storage? A water balance
should show all Inputs - Outputs = No Accumulation.
b, As currently designed, this is not a closed -loop recycle system because some
water is routed to a storage basin and then sprayed onto aggregate piles, which do
not drain back to the recycle basin.
c. As currently designed, the recycle basin does not capture the runoff from a 25
year, 24-hour storm and maintain one foot of freeboard at design operating
conditions. If the design is not a closed -loop recycle system capable of
maintaining that capacity, the design calculations must demonstrate compliance
with total suspended solids (TSS) and settleable solids (SS) permit limits (see the
bottom of page 3 on the NOI application form). No calculations that show that
settling and retention time will be sufficient to meet TSS and SS effluent limits in
the event of a discharge were included.
d. What is the design operating water.depth of the recycle basin? The design storm
depth is included in the volume calculation, but this volume does not account for
how much water is likely to be present at the time of rainfall. Also, will sufficient
volume be available to maintain freeboard when solids have accumulated, prior to
clean -out? At what level will solids be cleaned out?
e. There is no information about the temporary storage basin. How much water can
this basin hold, and what will be the maximum level of water under operating
conditions? What is the drainage area to that basin, and what size storm will it be
able to contain without overflowing?
5. pH Adjustment: There is no pH -adjustment mechanism designed into any of these
treatment systems. Please address.how pH will be controlled.
a. Even if lowering pH is not critical for reusing the water in concrete manufacture,
then unless a closed -loop recycle system is designed to contain the 25-year, 24-
hour storm (with one foot of freeboard) under design operating conditions, the
treatment facility must include pH adjustment to meet effluent limits of a pH
between 6-9 S.U. in the event of discharge. DWQ prefers.to see an automated
pH -adjustment system (for example, chemical or COz feed).

b. The current design routes water from the recycle system to a storage basin used
for wetting down aggregate piles,•and that water does not drain back into the
recycle system. It is likely that any water draining from the aggregate piles will
not meet pH limits unless treated.
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.
In communications with DWQ staff, you indicated that treatment systems at this site were built
prior to application for this general permit and ATC. It is important to apply for coverage under
the NCG140000 permit and an ATC before constructing treatment systems because alterations to
the system that may be required after installation can cost your operation unnecessary delays and
money, including fines for noncompliance with North Carolina General Statutes and rules.
Please keep this 90-day timeframe in mind for any future projects that involve wastewater
treatment or recycle systems.
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. Please be advised that on September 1,
2007, the application fee for a general permit increased to $100.00.
The NOI application is being returned to you with this letter. If you have any questions
concerning this matter, please contact Bethany Georgoulias at [phone], extension 529.
Sincerely,
for Coleen H. Sullins

In an eight (8) hour.day of production, the niaximwn yardage will be'240 cubic

yards of concrete produced with 8400 gallons of water used. This means the 6000
gallon storage tank will not support all the water used; therefore, a public ater
su 1 will supplement the recycle supply. See design calculations in No. 4 to
follow.
3. Agaresate Pfle Irripation: This operation is eliminated as water will be added as
needed at the batching operation. Moisture test will be performed on the aggregate
a minimum of twice a day to determine the need of added water in the batching
operation.
a. Design Calculations and Basis for Recycle System:
a. Each washout will generate an amount of water equal to 75 gallons and this
75 gallons will go into the wastewater basin which will hold 820 Cu. Ft., of
water in cell 1 before it spills into cell 2. 820 Cu. Ft. of water will be 4298
gallons of storage area in cell 1. The estimated maximum number washouts
will be 24 trucks times 75 gallons which will be 1800 gallons of water
going into cell 1 of the basin. When cell 1 fills with 4298 gallons it will
begin to spill into cell 2 which will be allowed to accumulate six inches of
water, or 1806 gallons at which time cell 2 will spill into cell 3, before the
pump will activate and send the waste water to the 6000 gallon storage tank.
The water in the storage tank, supplemented with public water, will used in
the production process.
