RE: Response to the NPDES Stormwater Compliance Evaluation Inspection, COC Number NCG140042;
Ready Mixed Concrete— Knightdale, Plant 1; NCG14000 General Permit for Ready Mixed Concrete;
Wake County
This letter is in response to the items needing our attention and a response back to you from the
stormwater compliance inspection at our Knightdale facility on June 5, 2015. First of all, I want to
explain to you about the length of time it has taken for us to respond to you. Your letter was dated June 8,
2015, but it was in a packet that was postmarked July 2, 2015. Because of the holiday and some internal
delays, I did not get your letter until late afternoon on July 9, 2015. We have taken to this time to respond
so I could review the items noted and the inspection with our Operations Manager, Jay Watkins. We -have
also went to the Knightdale plant and reviewed the site again ourselves and with our plant supervisor.
Our plant supervisor, Dwight Mitchell, resigned at the end of May to take another job, but came back at
the first of July and is supervising the plant and activities again. Below are the actions we have taken and
our responses to the items noted.
The stormwater plan was reviewed and certified. From the review, it was found that the plan did
not need modifying and the site plan did not need to be updated/changed. The annual employee
training has been completed and documented.
Where the unmonitored stormwater discharge was observed at the driveway heading onto Wake
Stone road, we have put in a berm at corner of ditch by drain pipe and we have raised the grade at
the driveway to try to push the water into the ditch and into the drain pipe. More importantly, we
cleaned out some blockage at the opening to the drain pipe and feel this will allow the flow from
the ditch to flow more freely into the pipe without blockage. We will visually monitor the flow at
this driveway to try to avoid creating an SDO here.
I apologize for the way our pit looked during your inspection. The pit at this plant has never been
that full in the 8 years I have been here, but our person responsible for cleaning the pits out was
working from behind, we had an acting plant supervisor for a month, and we had a unique
situation with the construction repairs which should not have been placed in the pit. Based on
observations since I have been here, the pit has never been within 5 feet of being full and 1 do not
feel that water gets out of our pit during a rain event. Even if it did, it would flow to the ditch
outside of our fence at the backside and into the ditch that leads to our settlement basin. Looking
at our site plan this is accounted for on the plan and is monitored in our analytical sampling from
our SDO. We have dug the pit out and it is probably 15 feet deep now. We will monitor to make
sure it does not reach the close to full level that was observed in vour inspection. 1 have not had

our environmental firm come out to provide calculations for 25 year storm but I will schedule no
later than August 3, 2015, unless you notify me that it is not required of us to do so anymore. I
have provided a picture of the pit now that it has been dug out.
4. There was evidence of a spill or leak that was probably old around the compressors behind the
storage building. The area was cleaned up and the compressors have been inspected and were not
showing any evidence of a current leak as inspected.
I want to thank you for taking the time to inspect our facility and communicate your concerns with our
Operations Manager. I am disappointed in particular about the way our pit looked at this particular
inspection. We want to convey our concern for our environmental responsibilities to our state
environmental agencies when they come out for inspections. We have tried to implement corrections for
compliance based on your comments and our knowledge ofour facility at Knightdale. With that being
said, we do battle a difficult situation in our industry daily in that trucks have to be rinsed regularly and
concrete returned from jobsites has to be dealt with daily and inmost cases with limited space. We hope
that you can see this also and understand what we deal with also regularly with pits and clean out from
pits. Just to let you know we try our best to sell returned concrete, put it in blocks, and we have just
recently starting using a product that helps convert returned concrete into basically stone to be resold or
used to produce concrete. We just started doing this at Knightdale and have about 75-100 tons of it on
hand.
Our plants are generally open based on daily production requirements. Please feel free to contact Jay
Watkins, Raleigh/Durham Operations Manager, the local Plant Supervisor or myself when you would like
to perform an inspection of any of our facilities. Jay and/or I can be reached at 919-790-1520.
Very truly yours,

Dear Mr. Tart:
Staff from the Department of Environment and Natural Resources conducted a stormwater compliance
inspection on June 8, 2015 for permit no. NCG 140242 as part of a multimedia inspection of your facility.
We appreciate the assistance provided by Jay Watkins and Bruce Creech during the inspection. Please
reference the attached inspection report checklist and summary in addition to the comments provided
below.
The facility appeared to be in compliance with a majority of permit requirements and a stormwater
management program has been implemented, however, a number of items do require your attention as
follows:
The stormwater pollution prevention plan appeared to best modified in 2011 and contained
most of the required components however, it should b pdate C nd certified annually, and
® employee training must be documented for each year. Likewise, t site plan or map should be
reviewed and updated as appropriate to match existing conditions.
AtIQ(nmonitored stormwater discharge outfall (SDO) location was observed at the southwest
corner driveway/ ditch crossing and should be brought up in grade to convey stormwater into the
adjacent ditch, effectively eliminating this SDO location as discussed with facility personnel.
Alternatively, if no changes are made, the SDO shall be monitored for analytical and qualitative
parameters in accordance with the permit. .
The earthen truck wash pit occasionally overflows and commingles with stormwater flowing to
the existing SDO. This wastewater effluent does not have pH control measures in place and is
not currently monitored/sampled as a process wastewater. Facility staff explained that pit water
is sprayed on a large waste pile to soak in as a means to manage freeboard level rather than

Inspection Summary:
A multi -media pilot program inspection was conducted by Division staff from Water Resources, Energy, Mineral and Land
Resources, Air Quality, and Solid Waste on June 5, 2015 to evaluate compliance with NPDES stormwater and air quality
permits issued to the facility. The stormwater inspection results for NCG140242 are presented below.
The stormwater pollution prevention plan (SPPP) was reviewed and contained most of the required components however, it
needs to be updated and certified annually, and employee training must be documented for each year. Likewise, the site
plan should be reviewed and updated as appropriate to match existing conditions. Secondary containment is provided for
the bulk storage of liquid products onsite.
Qualitative monitoring is performed semi-annualiy in accordance with the permit. Vehicle maintenance is not conducted
onsite other than minor greasing or topping off oil levels. Analytical monitoring for stormwater has been conducted twice
per year at the ditch SDO location at the southeast corner of the site prior to discharge to a pond which overflows to the
creek. Results indicated compliance with stormwater benchmark concentrations. However, the earthen wash pit which
occasionally overflows and commingles with stormwater flowing to the SDO, is not sampled as a process wastewater, nor
does it have pH control.
Further, the pit has been partially filled from both concrete deposition and utility construction/repairs, and does not have
sufficient volume to operate as a recycle pit and contain the 25-year, 24-hour storm for its existing drainage area. Facility
staff explained that pit water is not currently recycled back into concrete production but is sprayed on a large waste pile to
soak in as a means to manage freeboard level. As such, pit effluent must be sampled going forward or reconfigured to
capture and hold the 25 year storm with supporting calculations provided to the Division.
A potential SDO location was observed at the southwest corner driveway/ ditch crossing and should be brought up in grade
to force stormwater into the adjacent ditch, effectively eliminating this SDO location. Alternatively, it may be monitored as
another SDO. Significant oil residue was observed around two large air compressors and must be addressed and cleaned
up.
Air quality inspection results are covered under separate report. No solid waste or land resource program violations were
observed.

Knightdale, North Carolina, Wake County
Facility ID Number: 9200584
Air Permit Number: 08352 R07
Fee Class: Small
Dear Mr. Walters:
June 5, 2015, Maureen Conner and Lori Phillips of the North Carolina Division of Air Quality (DAQ)
along with Ray Williams (DWM), Cory Larsen (DWQ), and John Holley (DEMLR) conducted a multimedia
compliance inspection of the subject facility. At that time, it was learned that there was a violation of Air
Permit Stipulation B.6. This stipulation states:
In accordance with 15A NCAC 2Q .0309, this permit is subject to revocation or modification
by the DAQ upon a determination that information contained in the application or presented
in the support thereof is incorrect, conditions under which this permit was granted have
changed, or violations of conditions contained in this permit have occurred. In accordance
with G.S. 143-215.108(c)(1), the facility shall be properly operated and maintained at all
times in a manner that will effect an overall reduction in air pollution. Unless otherwise
specified by this permit, no emission source may be operated without the concurrent
operation of its associated air cleaning device(s) and appurtenances.
The air permit authorizes the facility to construct and operate a specific list of air emission sources
and/or air cleaning devices and appurtenances as described in Air Permit No. 08352R07. Emission source 1D
TLP-01.1, truck loading point has a baghouse control system ID 131-1-01.1 installed as an air cleaning device.
However, based on statements by facility personnel and observations during the June 5, 2015 compliance
inspection, it was noted that there was excess visible emissions above 20 percent opacity being emitted. It was
also observed by the inspector that your baghouse's magnehelic gauge was reading 5 inches water column, even
though facility records indicated two days prior to the inspection it was reading 3 inches water column.
According to your facility staff the increased reading could indicate that bags need to be replaced. Facility staff

also noted to the inspectors that it appeared the ductwork was filled with material. Therefore, it appears the
truck loading point and associated air pollution control device were not operating in a manner that would reduce
overall air pollution.
This Notice of Violation is hereby issued to Southern Equipment Co (dba RMCC) - Knightdale — Plant # 1
for failure to comply with the above air permit condition. It is also requested that a written response to this
Notice of Violation indicating actions taken to ensure permit compliance be submitted to this Office as
quickly as possible, but no later than June 30, 2015. This violation and/or any future violations are subject to
the assessment of civil penalties as per the authority of North Carolina General Statute 143-215.114.
Our office recommends that you or a company representative conduct a complete inventory of all air
emission sources and/or air cleaning devices at your facility and assure that all sources are permitted that are
required to be. Also, you are advised to review your Air Permit and become familiar with the record keeping
and reporting requirements.
Your cooperation is this matter is appreciated. If you have any questions, please do not hesitate to call Maureen
Conner, Environmental Engineer, or Steve Hall, Compliance Supervisor, at [phone].

Dear Permittee:
Division of Water Quality
Coleen H. Sullins
Director
August 1, 2011
Dee Freeman
Secretary
Subject: NPDES Stormwater Permit Coverage Renewal
Ready Mixed Concrete - Knightdale, Plant 1
COC Number NCG140242
Wake County
In response to your renewal application for continued coverage under stormwater General Permit NCG140000
the Division of Water Quality (DWQ) is forwarding herewith the reissued General Permit. 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).
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of General Permit NCG140000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form for Stormwater
• Two copies of the DMR Form for Wastewater
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater and/or wastewater, 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 the changes in the reissued permit. If your Certificate of Coverage (COC) restricts
authorization to discharge stormwater only (or other limited terms), you must contact the Stormwater Permitting
Unit if you would like to request a modification to your COC.
The first sample period of your permit begins July 1, 2011. However, because of the delayed mail -out of permit
packages, your facility is expected to attempt to sample during the first sampling period, and must comply with
sampling requirements beginning during the second sampling period. Your facility must sample a representative
storm event between January 1 and July 30, 2012 (for stormwater sampling), and/or sample wastewater between
October 1, 2011 and December 31, 2011 (or, if applicable, report "No Flow", as outlined in Part V, Section E).
Additionally, your facility has 6 months from the time of receipt of the permit to update SPPP to current standards.
The more significant changes in the General Permit since your last Certificate of Coverage include the following
(please note the names and numbers of sections have been changed from the previous permit revision):
Part II:
• Authorization to Construct (ATC) language was added to the permit and adapted to fit NCG140000.
Part III:
• The Stormwater Pollution Prevention Plan (SPPP) section has been updated to the most current
language of our permits. Some additional conditions specific to this industry have been added to the
SPPP language.
Part IV:
• Sections A & B: Revised provisions require stormwater discharges be sampled twice per year (instead of
annually), and sampling results shall be compared to new benchmark values. (The previous cut-off
concentrations have been removed).

• Sections A & B: Revised provisions require the permittee to execute Tier One, Two & Three response
actions: Tier One requirements for a first benchmark exceedence, and/or Tier Two response for a second
consecutive benchmark exceedence, if applicable. Tier Two requires that the permittee institute monthly
monitoring (reported to the appropriate Regional Offices) instead of twice -per -year monitoring. Monthly
monitoring shall be done until three consecutive monitoring events show no benchmark exceedences.
• Sections A & B: This permit now contains a provision that four exceedences of any benchmark will trigger
increased DWQ involvement in the permittee's stormwater management and control actions (Tier Three).
DWQ may direct the permittee to apply for an individual permit, institute specific monitoring, or may direct
the implementation or installation of specific stormwater control measures.
• Sections A & B: Failure to perform analytical stormwater monitoring requires that the permittee begin a
monthly sampling scheme for both industrial stormwater discharges and/or stormwater discharges from
VMA areas (where applicable). After 6 months of monthly sampling, the permittee may return to semi-
annual sampling, unless otherwise specified by DWQ.
• Sections A & B: A lower TSS benchmark of 50 mg/I for HOW, ORW, PNA and Tr Waters was added to
this permit for these more sensitive waters.
• Section B: The monitoring parameter Oil & Grease has been replaced by the parameter Total Petroleum
Hydrocarbons.
• Sections A, B & C: Inability to sample due to adverse weather must be reported in the SPPP.
• Sections A, B & C: The terminology "Representative Storm Event" has been replaced by "Measurable
Storm Event" in response to comments from industry groups. A measurable storm event is a storm event
that results in an actual discharge from the permitted site outfall. The previous measurable storm event
must have been at least 72 hours prior, unless the permittee is able to document that a shorter interval is
representative for local storm events during the sampling period, and obtains written approval from the
local DWQ Regional Office.
• Section C: Qualitative monitoring must now be conducted semi-annually and is tied to the same
measurable storm event as the analytical monitoring.
• Section C: If the permittee fails to respond effectively to problems identified by qualitative monitoring, the
permittee may be required by DWQ to perform corrective action.
• Section D: This section has now been consolidated to one section with one set of combined tables for all
types of authorized wastewater discharges.
• Section D: The wastewater analytical monitoring schedule has been set to quarterly.
• Section D: TSS limits have been revised for PNA, Trout and HOW waters per rule requirements in 15A
NCAC 02B .0224.
• Section D: 7010-based flow limits have been set for PNA waters per regulations in 15A NCAC 02B.
• Section D: TPH monitoring requirements have been added to wastewater monitoring when stormwater
runoff from VMA areas commingles with wastewater.
• Section D: This wording in the permit has been removed: "For facilities which route stormwater and all
process wastewater to a recycle system, no analytical monitoring of process wastewater discharges is
required if that recycle system discharges as a result of a 10-year 24-hour (or larger) precipitation event."
Part V:
• Section A: For existing facilities previously permitted and applying for renewal under this General Permit:
New elements of the Stormwater Pollution Prevention Plan for this permit renewal shall be developed and
implemented within 6 months of the effective date of the initial Certificate of Coverage issued pursuant to
this General Permit and updated thereafter on an annual basis.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit does
not affect the legal requirements to obtain other permits which may be required by DENR, 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
these members of the Stormwater Permitting Unit: Jennifer Jones [phone], Ken Pickle [phone], or
Bethany Georgoulias [phone].
Sincerely,
far Coleen H. Sullins

My mistake on lab results, had this Pt. confused with Garner, which we
did twice. As you saw in your visit, landscape has created over 150' of
vegetative sheetflow before the settlement area surrounded by riprap.
Storm water seeps through and around rocks to vegetated swale which
travels to Wake Stone Lake.
In reference to other years' Analytical testing, with change of Plant
managers in 2005, Dwight Mitchell has done the Qualitative Monitoring,
but only listed "No Discharge" on the 2006 reports while the sheetflow
and vegetation restictions have been applicable for several years.
Thank you,

Dear Mr. Austin:
Michael F. Easley, Governor
William G. Ross, Jr., Secretary
North Carolina Department of Environment and Natural Resources
Coleen 11. Sullins, Director
Division of Water Quality
On June 25, 2008, Ms. Stephanie Brixey of the Raleigh Regional Office conducted a stormwater evaluation
inspection of Ready Mixed Concrete Co. facilities located on Unicon Drive, Forestville Road and Old Garner
Road. The assistance of James Walters, Region 1 Manager, Dexter Tart, Asset Manager, and yourself was ,
appreciated as it eased the inspection process.
The following observations were made:
Ready Mixed Concrete Co. - 5025 Unicon Drive - NPDES Permit Number NCG140216
The facility does have a Stormwater Pollution Prevention Plan (SPPP) on site. ;The Facility Inspection
program includes monitoring the outfall, semi-annual housekeeping inspections, and secondary
containment inspections semi-annually, annual inspection of the dust filter system and inspecting for
spills and releases. Employee training is documented.
The process water is contained in a closed loop system and the water is recycled and mixed with
concrete. The water enters in to a four -pit area, goes through a filtering system; pH adjustment and a
CO2 system before being stored for re -use.
The area is bermed and ditched in such a way that all stormwater will pond on -site near the pit. It
appears that a discharge would only occur if there were continuous heavy rainfall over a period of time.
At his time no analytical monitoring has been conducted due to no discharge. Section C of the General
Permit No. NCG140000 states, "For facilities which route stormwater and all process wastewater to a
recycle system, no analytical monitoring of process wastewater discharges is required if that recycle
system discharges only as a result of a 10 year - 24 hour precipitation event."

NPDES Stormwater Permit NCG140242

Dear Mr. Spence:
Alan W. Klimek, P.E., Director
Division of Water Quality
On December 29, 2004 Myrl Nisely of the Raleigh Regional Office of Division of Water Quality made a
compliance inspection at the Knightdale facility. The help provided by Donny McHenry was appreciated.
See the attached checklist. Comments are:
The SPPP manual contained all the required components. Significant Spills -data sheets had no entry for
2004, so needs to be updated. The record near the beginning of the manual had a 2002 date, but in the
data filed at the back, there was an entry for 2003. The entire manual needs to have a documented
annual review.
2. The manual had no analytical sampling data for 2004. Mr. McHenry said there had been no flow. Yet,
our later discussion and observations during a site tour showed that water regularly leaves the washout
pit. There may be confusion about sampling for various parts of the permit and whether rain is required
for sampling to take place.
The permit can be thought of as having two parts, one for "pure" stormwater, and one for process water
discharges. The stormwater section requires sampling during a rain event. The test results are compared
to cutoff concentrations and, if low enough, can exempt the plant from further sampling of stormwater
until the last year of the permit cycle. In contrast, the process water in Section C can be sampled
anytime there is runoff occurring because a process is taking place, and does not have to be done during
a rain storm, unless a completely closed loop recycle system is involved. Permit limits must be met to
have an allowable discharge. This testing must be done every year — there is no cutoff exemption.
So in the case at Knightdale, the pit overflows with some regularity and should have been sampled
during 2004. The series of stone barriers in the overflow channel is apparently successful in attenuating
solids to desired levels. However, pH may still require some kind of neutralization procedure.

Ready Mixed Knightdale CEI
December 29, 2004
The ditch around the right side of the site (viewed as one comes in the driveway) probably can be
certified as a stormwater outfall free of process water. A judgment will be needed by Ready Mixed to
verify whether this is true. A second sample point for that flow needs to be established near the fence,
much like the other sample point for the pit overflows.
The two flows combine soon after they enter land owned by the Quarry, then travel through vegetation
before entering a large pond owned by the Quarry. This pond overflows into Beaverdam Creek, or an
unnamed tributary of that creek. Please take steps to see that in the future the limits are met at the fence
line for the pit overflow release.
3. It was noted that the manual contains a data reporting form for the five-year permit cycle that began in
August 2004. Older blank forms with dates for the cycle just ended can (should) be discarded.
If you have any questions or comments about this inspection, please contact me at 919-471-4700.
