Inspection Summary:
On May 10, 2018 this facility was inspected for compliance. Inspection was conducted with Robert Canipe and Jeff Lamm
on site. During the inspection, the following items were noted.
1) The drainage swale leading to outfall 1 is filling up at several of the "check dams" and requires maintenance.
2) The drainage swale may need to be extended, or a diversion berm added to allow the Swale to properly capture all
stormwater on site (as discussed).
3) The wastewater management system on site should be finished and implemented as soon as possible to prevent
contamination of stormwater with wastewater.
4) Analytical and Qualitative monitoring has not been conducted on site. This should immediately be addressed. A sample
should be obtained with the next rain event. If analytical data is above benchmark or outside the accepted parameters,
please contact this office as soon as possible to discuss alternatives.
If you have any questions, please contact me at [phone],
Thank you

Permit: NCG140407 owner -Facility-. Roger Kerr
Inspection Date: 07l28/2016 Inspection Type . compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Present during the inspection were Robert Canipe with Kerr Concrete, Linda Wggs with DWR, and Richard Morris with
DAQ. This inspection was performed as a multimedia inspection. Note: this is the first inspection ever conducted for the
stormwater permit NCG140407 at this Kerr facility, and the site was not in operation at the time of inspection. Items noted
below need immediate attention in order for the facility to come into compliance with the NCG140407 stormwater permit.
Stormwater Pollution Prevention Plan (SPPP or SWPP):
Part Ili, 1-10: The SPPP appears to be a good document put together for Kerr, however it has not been completely
implemented. It is a permit requirement and an essential component for compliance that all aspects of the SPPP be
implemented. Please carefully review Permit NGG14DDDD Part III 1-10 and the SPPP and implement all required items.
Some items are specifically noted below that need your attention.
1. Implement the SPPP onsite and update it annually.
2. Maintain all inspection records. BMP Summary is to be reviewed and updated annually.
3. Develop and maintain log books for employee training.
4. Confirm that responsible parties and all signature pages are current.
5. Analyze site for spill and leak potential and keep emergency spill cleanup kits near area with high spill or leak potential
i.e. cargo containers that store the concrete additives.
6. Keep a list onsite of all detergents, additives, polymers, brighteners and any other solvent, cleaning agents, or like
chemicals used onsite with respective volumes and MSDS sheets (NCG140000 Part II Section 8.9).
7. Revise the site map to clearly identify the required items (NCC 140000 Part III, 1.c.),
8 Much of the Wastewater and storm water leaving this site currently has no treatment.
9 Wastewater pit is not what is on plans. What is onsite appears considerably undersized and is not a proper wastewater
system as designed on the plans.
Analytical Monitoring:
Part IV Section D: Analytical monitoring for process wastewater is required 4 times a year and shall be reported on the
Process Wastewater -Quarterly Discharge Monitoring Report form provided to Robert Canipe via email on 5/3/2016. This
requirement is noted in' Part V table 9 of the Stormwater Pollution Prevention Plan (SPPP or SWPP).
Analytical monitoring has not been taking place. Wastewater -Quarterly Discharge Monitoring Report as required in Part V
Section E. Since sampling has not taken place, Part IV Section D Page 10 of 11 to institute monthly monitoring for at least
6 months is in effect immediately.
Qualitative Monitoring:
Part IV Section C: Qualitative Monitoring is required twice a year at all outfalls and shall be reported on the Qualitative
Monitoring Report form provided to Robert Canipe via email on 5/312016.
Outfalls:
Possible outfalls were observed during the inspection; one is the outfall approximately 150 feet south of the office building to
the edge of the property where the grass is maintained. Tree line marks where outfall begins. Two other possible outfalls
are located in the center of the property. One is on the east side at the bottom of a grassy slope and drains into the main
drain for the stream diversion pipe line. The other is on the center west side of the stream diversion pipe line. Both lines
appear to feed into the main line carrying the stream beneath the entire property.
All outfalls need to be determined and marked on map and sampled according to the permit.
This facility needs to perform a comprehensive evaluation of all outfalls, in particular the two outfalls with grates on the East
and West center side emptying into the diverted stream underneath the property.
Secondary Co ntainment/Spills:
The shipping containers being used for chemical storage will not require secondary containment as long as the inside area
is provided with sufficient leak proofing to avoid liquid leaving the containers. A secondary containment is required for two
containers with a combined storage capacity of greater than 1,320 gallons. There was chemical residue noted in the
pumpldistribution area of the container; better housekeeping and/or spill documentation is needed. Note SPPP 8.4 and Log
Cl and C2 in Appendix C, and Log E in Appendix E of the SPPP.

3) Pre -inspection Conference: On July 28, 2016,1, Linda Wiggs with DWR and Richard
Morris with DAQ met onsite with Robert Canipe with Kerr Concrete. Based on our
conversations with him, we discussed the following:

' a) Verified the contacts based on FACFiNDER.
b) I examined their bag filter logbook that is kept in the dispatchers control room.
They keep a very good log with recent entries of maintenance and bag change out.
Last annual inspection for all control devices was performed on February 10, 2016
and April 13, 2016.
4) Process Description: (AP-42)
Concrete is composed essentially of water, cement, sand (fine aggregate), and coarse aggregate.
Coarse aggregate may consist of gravel,'crushed stone, or iron blast furnace slag. Some specialty
aggregate products could be either heavyweight aggregate (of barite, magnetite, limonite,
ilmenite, iron, or steel) or lightweight aggregate (with sintered clay, shale, slate, diatomaceous
shale, perlite, vermiculite, slag, pumice, cinders, or sintered fly ash). Concrete hatching plants
store, convey, measure, and discharge these constituents into trucks for transport to a jab site. In
some cases, concrete is prepared at a building construction site or for the manufacture of
concrete products such as pipes and prefabricated construction parts. The raw materials can be
delivered to a plant by rail, truck, or barge. The cement is transferred to elevated storage silos
pneumatically or by bucket elevator. The sand and coarse aggregate are transferred to elevated
bins by front end loader, clam shell crane, belt conveyor, or bucket elevator. From these
elevated bins, the constituents are fed by gravity or screw conveyor to weigh hoppers, which
combine the proper amounts of each material. Truck mixed (transit mixed) concrete involves
approximately 75 percent of U. S. concrete batching plants. At these plants, sand, aggregate,
cement, and water are all. gravity fed from the weigh hopper into the mixer trucks. The concrete
is mixed on the way to the site where the concrete is to be poured. Central mix facilities
(including shrink mixed) constitute the other one-fourth of the industry. With these, concrete is
mixed and then transferred to either an open bed dump truck or an agitator truck for transport to
the job site. Shrink mixed concrete is concrete that is partially mixed at the central mix plant and
then completely mixed in a truck mixer on the way, to the job site. Dry.batching, with concrete. _
mixed and hauled to the construction site in dry form, is seldom, if ever, used.
5) Inspection: The plant was not operating on the day of the inspection. Robert Canipe stated,
last year this facility only operated 50% of the year.
a. ES4 Truck load out: Not Operating.
b. ES1 and ES2: Not Operating.
6) Stipulation Review:
A.3 2D.0515 — Particulate Control (process weight). In compliance. Last
engineering review by indicated compliance with bagfilter control.
A.4 2D.0521 —Visible Emissions. In. compliance. Not Operating.
A.6 2D.0540 — Fugitive Dust Control. In Compliance. No fugitive dust observed.

A.7 . 2D.0611 -- Bagfilter Requirements. In compliance. I reviewed the facility log
book and found recent entries of system maintenance and bag change. out. Latest
entry dates were February 10, 2016 and April 13, 2016.
7) Reporting requirements:
There are no reporting requirements in the current permit.
8) 112R Status: Based on the facility's inventory, it was decided that they are not subject to
112R reporting requirements.
9) Comments and Compliance Statement:
Kerr's Ready -Mixed Concrete Co., Lenoir Inc. appeared to be in compliance by
inspection on July 28, 2016,
10) 5 Year Compliance History:
No violations in past 5 years.

Linda,
I'm sending you a copy of the add. info. I received for the subject application. I'm satisfied that the submitted info
meets the requirements of the permit. I just need to get sealed plans sent to me (I'll send you a copy when I get them).
The plans they submitted this time were not sealed.
Does ARO has any concerns with issuing the COC for the subject facility?
Thanks.

Dear Mr. Patterson:
On behalf of Kerr Concrete (KERR), CP Engineering and Environmental Solutions (CPEES) is
pleased to respond to your additional information request dated March 29, 2011. The responses
to your questions are as follows:
1) The calculations for the recycle system do not include a water balance analysis. How
will all the captured water from the 25 yr storm event he reused so that the system does
not overflow?
Response
KERR had decided to reuse the water collected in the pits in their batch operations. As per
the attached calculations (40 to 50 batched per year and 250 gals/batch), approximately 8.9
days are required to use the collected water (98,736 gals) in the plant.
2) Please clarify the size of the drainage area (DA) going to the recycle system. The
narrative states 22,216, but the calculations state 20,473 sf
Response
The size of the drainage area is 0.616 acres (0.576 ac + 0.04 ac) or 26833 sff., including the
stockpile wetted area. The drum wash and the recycling pits areas are also included in the
above area calculations. The area boundary shown in the drawing is either re -contoured or
raised (bermed) in order to control the process water to the designated area. Any area not
included in the drainage area calculations will not contribute to the process water to be
recycled.
3) Recycle Pit Design:
a. The weirs for the flow through the differentpits are not shown or detailed.
b. The calculations and plan view show 60' long pits but the details show only 25'
long pits.

c. The calculations and footing sections show 5 ' deep pits, but the other details
show only 3' deep pits.
Response
a. The weirs (drain slots) are shown on the attached Figure 3.
b. The pit details are shown on the attached figures, Figure 3 and Figure 4. Based on the
calculations, CPEES has arrived at 4 pits (70ft long x 12ft wide x 5ft deep) and a sludge
drying area for the Lenoir Plant.
c. The pits are 5 feet deep and the details are shown on Figure 4.
4) Plans:
a. Please clearly show and identify the drum washout area and the stockpile
wetting area.
b. The DA delineation does not appear to include the recycle pit area, but needs to.
c. It is not clear how the area to the east of the plant will not drain into the plant
and then into the recycle system. It appears it will be based on the contours.
d. It appears that a portion of the delineated DA to the northwest will instead go to
the drop inlet shown and then bypass the recycle system.
e. Please clearly identify any stormwater only outfalls.
Response
a. The drum wash area and the stockpile wash area are identified in the attached Figure 3.
The process water from these two areas goes to the Pit # 1 in the recycle system.
b. The new DA includes the pit system. The DA included in this area equals to 0.616 acres
and the pit system is designed to hold 25-yr storm event for 0.616 acres.
c. The delineated areas are either raised (bermed) or re -contoured to avoid any non process
water going into the pit system.
d. The drop -inlet will be removed from this area and regarded to eliminate process water
reaching the underground pipe system.
e. Only one outfall is identified on the property and it was denoted on Figure 3.
It is my pleasure to complete this important project for Kerr Concrete and please call me at (704)
541-4042 if you have any questions or comments on this A to C permit application package.

4) Plans:
a. Please clearly show and identify the drum washout area and the stockpile
wetting area.
b. The DA delineation does not appear to include the recycle pit area, but needs to.
c. It is not clear how the area to the east of the plant will not drain into the plant
and then into the recycle system. It appears it will be based on the contours.
d. It appears that a portion of the delineated DA to the northwest will instead go to
the drop inlet shown and then bypass the recycle system.
e. Please clearly identify any stormwater only outfalls.
Response
a. The drum wash area and the stockpile wash area are identified in the attached Figure 3.
The process water from these two areas goes to the Pit #1 in the recycle system.
b. The new DA includes the pit system. The DA included in this area equals to 0.616 acres
and the pit system is designed to hold 25-yr storm event for 0.616 acres.
c. The delineated areas are either raised (bermed) or re -contoured to avoid any non process
water going into the pit system.
d. The drop -inlet will be removed from this area and regarded to eliminate process water
reaching the underground pipe system.
e. Only one outfall is identified on the property and it was denoted on Figure 3.
It is my pleasure to complete this important project for Kerr Concrete and please call me at (704)

Your facility's Notice of Intent (NOI) for permit NCG140000 was received by the Stormwater
Permitting Unit on February 24, 2011. However, a review of the application package showed that
the application is incomplete. Before the NOI can finish being processed please provide
information regarding the following:
1. The calculations for the recycle system do not include a water balance analysis. How will all
the captured water from the 25-yr storm event be reused so that the system does not overflow?
2. Please clarify the size of the drainage area (DA) going to the recycle system. The narrative
states 22,216 A, but the calculations state 20,473 sf.
3. Recycle Pit Design:
a. The weirs for the flow through the different pits are not shown or detailed.
b. The calculations and plan view show 60' long pits, but the details show only 25' long
pits.
c. The calculations and footing sections show 5' deep pits, but the other details show only
3' deep pits.
4. Plans:
a. Please clearly show and identify the drum washout area and the stockpile wetting area.
b. The DA delineation does not appear to include the recycle pit area, but needs to.
c. It is not clear how the area to the east of the plant will not drain into the plant and then

Hickory, Maiden, and Morganton Plants:
Application Returns (Return #s 1263, 1264, & 1265)
Catawba and Burke Counties
On February 24, 2011, the Division of Water Quality received the following application packages:
• Notice of Intent (NOI) requesting coverage and an Authorization to Construct (ATC) under general
stormwater and wastewater permit NCG140000 for the Lenoir Concrete Plant. We have accepted this
application, and it will be assigned to a Stormwater Permitting Unit (SPU) staff member for review.
• A request for an Authorization to Construct (ATC) only for modifications to the wastewater treatment
system at the Hickory Concrete Plant. [Please note this facility is already covered under NCG140000
by Certificate of Coverage No. NCG140104.] A preliminary review indicated some application copies
for this facility contained incorrect NOI forms from other plants and/or typos. Your consultant, Mr.
Chuck Pakala, requested the entire application package be returned directly to him to correct these
problems. Therefore, we are returning all three copies to Mr. Pakala (Return #1263).
There is no application fee for an ATC only. For that reason, check number 054747 is being returned to
you directly.

Application Returns (#1263, 1264, 1265)
March 2, 2011
Notice of intent (NOI) requesting coverage and an Authorization to Construct (ATC) under NCG140000
for the Maiden Concrete Plant. A preliminary review indicated some application copies for this facility
contained incorrect NO1 forms from other plants and/or typos. Your consultant, Mr. Chuck Pakala,
requested the entire application package be returned directly to him to correct these problems.
Therefore, we are returning all three copies to Mr. Pakala (Return #1264).
Notice of Intent (NO]) requesting coverage and an Authorization to Construct (ATC) under general
stormwater and wastewater permit NCG140000 for the Morganton Plant. A preliminary review
indicated some application copies for this facility contained incorrect NO1 forms from other plants
and/ortypos.
After further review, the Stormwater Permitting Unit (SPU) has determined the submitted materials
are insufficient for us to continue processing this application. Therefore, we are returning the entire
application package to you (Return #1265). A summary of items is included below to help you address
deficiencies so that you can resubmit the application:
1. Plans and Specifications: No plans and specifications for the recycle system were included with the
application package. The detail for the Temporary Sediment Trap is not relevant to the NCG140000
application. No detailed plans or As -Built drawings were included for what was described as a five pit
recycle system. In addition, the plans submitted for the site map only show four pits. As -Built
drawings of the recycle pit system with current dimensions should be provided.
2. Site Map: The site map provided was difficult to read, was not accurate, and did not show the detail to
substantiate information in the appendices of the application. Please verify the map includes all the
information requested in the NOI final checklist. For example, the map:
a. did not delineate drainage areas DA-1 through DA-4 discussed in the text, or any drainage
areas, or show direction of flow;
b, did not show a five pit recycle system (inconsistent with other information in the application).
c. did not show the location of stormwater discharge outfalls;
d. did not show where materials are stored (e.g., aggregate piles) or industrial activities occur;
e. did not clearly label the stormwater wet detention basin or show the flow it captures.
3. Recycle System Design Calculations: The calculations for the recycle system capacity do not include
the drainage area from the stockpile areas (we were unable to confirm without sufficient As -Built
plans). The NOI application indicates that stockpiles are wetted down. It is not clear whether or not
that wastewater flows to the recycle system. If that flow is not captured by the recycle system,
process wastewater is commingling with stormwater and being discharged elsewhere.
Please verify that any plans and/or calculations prepared by previous consultants adequately support
the NO1 if they are included as supporting documents. Attachments prepared by Mr. Nathan Turner indicated
his documents had been submitted to the Stormwater Permitting Unit in August 2008; however, our Unit has
no record of receiving or returning this project application as part of an NPDES NCG140000 application. Could
you provide information about when/if this project was submitted to the SPU?

The return of these applications 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.
The NOI application package for the Morganton Plant is being returned to you with this letter. The NOI
application packages forthe Hickory and Maiden Plants are being forwarded to your consultant, per his
request, to address the needed NOI corrections in a timely fashion. However, the check included with the ATC
request for the Hickory Plant is being returned to you directly because no fee applies. If you have any

Permit Application for Authorization to Construct
(A to Q a Process / Stormwater Recycling System
Kerr Concrete— Lenoir Plant
Lenoir North Carolina
NPDES General Permit No.: NCG140000
Certificate of Coverage: Not Yet Issued
1.0 FACILITY DESCRIPTION
Kerr Concrete -Lenoir Plant located at 1190 Bradford Mtn., Road, Lenoir, Caldwell County,
North Carolina, is a dry batch ready mix concrete plant for commercial supply. The primary
Standard Industrial Classification (SIC Code) for the facility is 3273 (Ready Mixed Concrete).
The approximate location of the facility on a US Geological Survey Map is provided on
Figure 1. The geographic site location can also be given as 350 52' 59.18" North Latitude and
810 33' 27.2" West Longitude. The subject facility is surrounded by light manufacturing and
residential areas and stormwater from the facility drains to Millers Creek located south of the
property. The stormwater from Millers Creek flows to Lower Creek and eventually to
Catawba River located south of the site. The details of surrounding properties are displayed
on an Aerial Map, Figure 2, attached with this report. The Lenoir Plant occupies
.approximately 4.37 acres of land and the paved area for operations. However, approximately
0.51 acres of area will be exclusively used for washwater/recycle operations. Stormwater
from this property flows to Millers Creek located south of the pro property, Figure 1. The
stormwater from Millers Creek flows to Lower Creek and eventually to Catawba River located
south of the site. Based on my review with NC Division of Water Quality web site, it is our
understanding that Millers Creek is classified as Class C (see attached table obtained from NC
DENR — Division of Water Quality Section web site for details -Attachment B). The
Stormwater from the facility is carried to Millers Creek via swales and sheet flow (Figure 3).
The Lenoir Plant will consist of an office building, a ready mix concrete plant next to the
office building, cement and fly -ash silos, a temporary pit system for washwater, and gravel
storage areas, and a concrete truck drum wash area. Lenoir Plant will have approximately 2 to
10 trucks and operates 8 hrs/day, 5 days/wk and 30 to 50 wks/year, depending upon the
weather and business conditions.
2.0 FACILITY OPERATIONS
The facility operations will include: a dry batch concrete plant, cement and fly -ash silos with a
dust control central vacuum system, sand and a small portion of gravel storage areas with
limited water sprinkler system (taken into process water consideration) and a truck washing
area.
CP Engineering and Environmental Solutions 1 A to C Permit Application
Tel: [phone] Kerr HRM Concrete - Lenoir
Email: cvpakala(a�carolina.rrxom 1190 Bradford Mtn. Road

Based on the request from the user, typical operations from this plant include: loading the
sand, gravel, and cement and fly -ash into a weigh scale which drops the dry mix into cement
trucks as a dry batch concrete mix. The dust extracted from the cement silo will be processed
through a NC DENR Division of Air Quality permitted bag filter system before released into
the atmosphere.
The loaded cement truck with concrete mix will be brought to a truck washing area for a
surficial wash before it goes out for the delivery. Occasionally, any left over concrete in the
concrete drum will be either used in making blocks or washed of at the plant in a truck
washing bay. Thus, process water will be generated at the plant for either recycling or
disposal. Based on our understanding of the facility operations, wash chemicals are located
near the wash pit area to collect any potential spills from these storage vessels. The oil storage
tank was kept far from the pits and it is secondary contained. Therefore, no oily water or
stormwater contaminated with chemicals will be released to the environment from the facility.
The facility has not applied for a NPDES General Permit (NCG140000) in the past and
therefore, applying now to obtain the NPDES permit and be complaint with the State Division
of Water Quality regulation. To meet the NPDES General Stormwater Permit requirements, a
Stormwater Pollution Prevention Plan (SWPP Plan) with Best Management Practices for
40 potential stormwater pollutant sources shall be prepared and implemented at the site.
All truck drums and drum chutes will be washed at the end of the day before parked for good.
Therefore, the locations where process washwater will be generated at the plant are:
• Surficial cleaning of the drum before leaving the site,
• Cement drum washing if left over concrete is brought back to the plant; and
• Drum and drum chutes cleaning at the end of the day.
3.0 PROCESS WASHWATER CALCULATIONS
Based on our discussions with the Lenoir Plant Manager, it is our understanding that
approximately 25 to 40 batches per day will be completed in the summer time and 25 batches
per day will be completed in the winter time using 10 trucks. Approximately 5 to 10 gals of
water will be used for surficial washing of the truck per batch. Approximately 5 to 10 gals of
water will be used to wash drum chutes per truck per day at the end of the day.
Approximately 200 gals per day per drum will be used to wash at the end of the day.

4.0 STORMWATER RUNOFF CALCULATIONS FOR A 25 YEAR AND
24-HR RAIN EVENT
According NC DENR-Division of Water Quality NPDES General Stormwater Permit
requirements, recycle systems are considered wastewater treatment per 15A NCAC 2H .0203
and all wastewater discharges must meet a total suspended solids (TSS) limit of 30 mg/I, a
settleable solids (SS) limit of 5 m1/l, and pH between 6-9 SU or must demonstrate that the
recycle system has sufficient capacity to contain 25-year, 24-hr rainfall event plus one foot of
freeboard under the design operating conditions.
To obtain an economic and workable solution to the proposed recycling system design, the
truck washing operations and process washwater generating points are all brought to one
location to reduce the drainage area for 25-yr, 24-hr calculations. Approximately 22,216 sq ft
or 0.51 acres of area including the small area for gravel washing is expected to contribute to
the process washwater from the facility (Figure 3). All washing operations beyond this
designated area are prohibited at the facility and the drivers will be trained to adhere to this
new policy for meeting the Stormwater regulations. CPEES has performed stormwater
calculations for a 25-yr, 24-hr rain event for 0.51 acres and approximately 10,738 cubic feet
(cft) of runoff capacity is required to hold the designed rain event. The runoff volume and
weir design calculations are provided in Attachment A.
Please note, during a rain event, no plant operations will be conducted. Therefore, no
washwater is accounted for in the proposed recycle system design when 25-yr, 24-hr rain
event for stormwater is considered.

5.0 STORMWATER / PROCESS WASHWATER RECYCLE SYSTEM
DESIGN AND CONSTRUCTION DETAILS
The proposed recycle system is designed to capture all process washwater and stormwater
from a 25-yr, 24-hr rainfall event from the subject plant wash areas. The recycle system is
designed to hold entire runoff amount from the designed storm event. The approximate
drainage area involved in the process washwater is estimated to be 0.51 acres (Figure 3). The
25 year, 24-hr runoff volume from this drainage area is estimated to be 10,738 cft. A recycle
system designed for the estimated runoff is a four pit system with a drying bed for the waste
materials removed from the pit (Figure 3). The total volume of all the three pits were
designed to be sufficient to hold the entire 25 year, 24-hr run off volume. Please note KERR
strives very hard to control and mitigate migration of any contaminated stormwater from the
facility to the waters of US. Appropriate slopes/berms/walls are proposed to isolate the 0.51
acres of drainage area for the washwater / stormwater recycling operations (Figure 3).
All the four pits in the recycling system are sloped at the entrance in order for a front-end
loader to go into the pit for a periodic cleanup. However, a berm or a slope away from the pit
is placed in front of the second, the third and the fourth pit in order to divert the wash
wastewater entry into these pits. The cross -sectional and construction details of the pits are
shown on Figure 4.
CPEES designed a pit sludge storage area next to the truck washing operations in order to
control stormwater flow that is in contact with the pit sludge. The slopes of the truck washing
operations and the pit sludge storage area are directed toward the first pit of the four pit
recycling system in order to control and mitigate migration of stormwater contamination from
the washing operations.
The location of the recycling system along with stormwater flow directions and wash areas are
displayed on Figure 3. The construction details for the recycling system are displayed on
Figure 4. The 25 year, 24-hr stormwater runoff calculations are provided in Table l of this
report.
A sump pump with a level switch will be provided to pump water from the fourth pit as
required either to the plant or to the truck washing operations. This would help empty the
third pit to accommodate any possible rain event.
6.0 A to C CONSTRUCTION PERMIT APPLICATION
Based on our consultants' discussions with the State DWQ, it is our understanding that we
need to file a NCG 140000 Notice of Intent (NOI) Form to obtain A to C Permit to construct
the proposed process washwater / stormwater recycle system at the Lenoir Plant. A copy of
the NCG 140000 NOI is attached with the A to C Report for an approval.

NOTE: The designer must use judgment to select the appropriate C value
within the range for the appropriate
land use. Generally, larger
areas with
permeable soils, flat slopes, and dense vegetation should have
lowest C
values. Smaller areas with slowly
permeable soils, steep slcpes,
and
sparse vegetation should
be assigned highest C values.

The overland flow portion of flow time may be determined from Figure 8.03a.
The flow time (in minutes) in the channel can be estimated by calculating the
average velocity in feet per minute and dividing the length (in feet) by the
average velocity.
Step 4. Determine the rainfall intensity, frequency, and duration (Figures 8.03b
through 8.03g—source: North Carolina State Highway Commission,, Jan.
1973). Select the chart for the locality closest to your location. Enter the
"duration" axis of the chart with the calculated time of concentration, TC. Move
vertically until you intersect the carve of the appropriate design storm, then
move horizontally to read the rainfall intensity factor, i, in inches per hour.
Step 5. Determine peak discharge, O 00/sec), by multiplying the previously
determined factors using the rational formula (Sample Problem 8.03a).

Note:
Use nomograph Tc for natural basins with well-defined channels, for overland
flow on bare earth, and for mowed -grass roadside channels.
For overland flow, grassed surfaces, multiply Tc by 2.
For overland flow, concrete or asphalt surfaces, multiply Tc by 0.4,
For concrete channels, multiply Tc by 0.2.

s To obtain runoff depths
for CN's and other
rainfall
amounts not shown
in this table, use an arithmetic interpolation.
The volume of runoff from the site can be calculated by multiplying the
area of the site by the runoff depth.
Step 4. Detemune the peak rate of runoff for the design storm by adjusting for
watershed shape as follows:
a. Determine an "equivalent drainage area" from the hydraulic length of the
watershed using Figure 8.03n. Hydraulic length is the length of the flow
path from the most remote point in the watershed to the point of discharge.
b. Determine the discharge (cfsAnch of runoff) for the equivalent drainage
area from Figure 8.03o through 8.03q:
Figure 8.03o - for average watershed slopes 0-3%
Figure 8.03p - for average watershed slopes 3-7%
Figure 8.03q - for average watershed slopes 8-50%
Calculate the peak discharge, Q1, of the equivalent watershed by multi-
plying equivalent watershed area by runoff from Table 8.03c in Step 3b.

Dear Mr. Kerr:
Dee Freeman
Secretary
This letter is in follow-up to a site visit and file review of Stormwater Permits for Ready Mix
facilities. You have two facilities in the Asheville Regional Office regulatory area for the Division
of Water Quality; one facility in Caldwell County and one in Burke County. File review indicates
that these facilities are not covered under the required stormwater permit for ready mix industrial
activities. The following items need to be addressed:
Stormwater Permit Application
The Caldwell County facility needs to be permitted through the Notice of Intent (NOI), application
process. Please see the attached application.
Stormwater Permit Plan Review
The Burke County facility engineered plans need to be reviewed to determine if the design is
sufficient to avoid permitting that facility. Send a copy of the plans to the following address:
Stormwater Permitting Unit, Division of Water Quality, 1617 Mail Service Center, Raleigh NC
27699-1617; include a letter to Ken Pickle with this submittal asking for a courtesy review. Also
send a copy of the plans to my attention at the Division of Water Quality -Asheville Regional
Office at 2090 US HWY 70, Swannanoa NC-28778.
Required Response
The above noted submittals should be received by February 25, 2011.
Please contact me at [phone] or linda.wig sAnederingov, if I can be of any further
assistance.

Permit Application for Authorization to Construct
(A to Q a Process /Stormwater Recycling System
Kerr Concrete— Lenoir Plant
Lenoir, North Carolina
NPDES General Permit No.: NCG140000
Certificate of Coverage: Not Yet Issued
1.0 FACILITY DESCRIPTION
Kerr Concrete -Lenoir Plant located at 1190 Bradford Mtn., Road, Lenoir, Caldwell County,
North Carolina, is a dry batch ready mix concrete plant for commercial supply. The primary
Standard Industrial Classification (SIC Code) for the facility is 3273 (Ready Mixed Concrete).
The approximate location of the facility on a US Geological Survey Map is provided on
Figure 1. The geographic site location can also be given as 35' 52' 59.18" North Latitude and
810 33' 27.2" West Longitude. The subject facility is surrounded by light manufacturing and
residential areas and stormwater from the facility drains to= Milleis-Greek located south of the
property. The stormwater from Millers Creek flows to Lower Creek and eventually to
Catawba River located south of the site. The details of surrounding properties are displayed
Is on an Aerial Map, Figure 2, attached with this report. The Lenoir Plant occupies
approximately 4.37 acres of land and the paved area for operations. However, approximately
0.51 acres of area will be exclusively used for washwater/recycle operations. Stormwater
from this property flows to Millers Creek located south of the pro property, Figure 1. The
stormwater from Millers Creek flows to Lower Creek and eventually to Catawba River located
south of the site. Based on my review with NC Division of Water Quality web site, it is our
understanding that Millers Creek is classified as Class C (see attached table obtained from NC
DENR — Division of Water Quality Section web site for details -Attachment B). The
stormwater from the facility is carried to Millers Creek via swales and sheet flow (Figure 3).
The Lenoir Plant will consist of an office building, a ready mix concrete plant next to the
office building, cement and fly -ash silos, a temporary pit system for washwater, and gravel
storage areas, and a concrete truck drum wash area. Lenoir Plant will have approximately 2 to
10 trucks and operates 8 hrs/day, 5 days/wk and 30 to 50 wks/year, depending upon the
weather and business conditions.
2.0 FACILITY OPERATIONS
The facility operations will include: a dry batch concrete plant, cement and fly -ash silos with a
dust control central vacuum system, sand and a small portion of gravel storage areas with
limited water sprinkler system (taken into process water consideration) and a truck washing
area.

Email: cvpakala(a,carolina.rr.com 1190 Bradford Mtn. Road

Based on the request from the user, typical operations from this plant include: loading the
sand, gravel, and cement and fly -ash into a weigh scale which drops the dry mix into cement
trucks as a dry batch concrete mix. The dust extracted from the cement silo will be processed
through a NC DENR Division of Air Quality permitted bag filter system before released into
the atmosphere.
The loaded cement truck with concrete mix will be brought to a truck washing area for a
surficial wash before it goes out for the delivery. Occasionally, any left over concrete in the
concrete drum will be either used in making blocks or washed of at the plant in a truck
washing -bay. Thus, process water will be generated at the plant for eithenrecycling or
disposal. Based on our understanding of the facility operations, wash -chemicals are located
near the wash pit area to collect any potential spills from these storage vessels. The oil storage
tank was kept far from the pits and it is secondary -contained. Therefore, no oily water or
stormwater contaminated with chemicals will be released to the environment from the facility.
The facility has not applied for a NPDES General Permit (NCG140000) in the past and
therefore, applying now to obtain the NPDES permit and be complaint with the State Division
of Water Quality regulation. To meet the NPDES General Stormwater Permit requirements, a
Stormwater Pollution Prevention Plan (SWPP Plan) with Best Management Practices for
® potential stormwater pollutant sources shall be prepared and implemented at the site.
All truck drums and drum chutes will be washed at the end of the day before parked for good.
Therefore, the locations where process washwater will be generated at the plant are:
Surficial cleaning of the drum before leaving the site,
v Cement drum washing if left over concrete is brought back to the plant; and
s Drum and drum chutes cleaning at the end of the day.
3.0 PROCESS WASHWATER CALCULATIONS
Based on our discussions with the Lenoir Plant Manager, it is our understanding that
approximately 25 to 40 batches per day will be completed in the summer time and 25 batches
per day will be completed in the winter time using 10 trucks. Approximately 5 to 10 gals of
water will be used for surficial washing of the truck per batch. Approximately 5 to 10 gals of
water will be used to wash drum chutes per truck per day at the end of the day.
Approximately 200 gals per day per drum will be used to wash at the end of the day.

4.0 STORMWATER RUNOFF CALCULATIONS FOR A 25 YEAR AND
24-HR RAIN EVENT
According NC DENR-Division of Water Quality NPDES General Stormwater Permit
requirements, recycle systems are considered wastewater treatment per 15A NCAC 2H .0203
and all wastewater discharges must meet a total suspended solids (TSS) limit of 30 mg/l, a
settleable solids (SS) limit of 5 ml/l, and pH between 6-9 SU or must demonstrate that the
recycle system has sufficient capacity to contain 25-year, 24-hr rainfall event plus one foot of
freeboard under the design operating conditions.
To obtain an economic and workable solution to the proposed recycling system design, the
truck washing operations and process washwater generating points are all brought to one
location to reduce the drainage area for 25-yr, 24-hr calculations. Approximately 22,216 sq ft
or 0.51 acres of area including the small area for gravel washing is expected to contribute to
the process washwater from the facility (Figure 3). All washing operations beyond this
designated area are prohibited at the facility and the drivers will be trained to adhere to this
new policy for meeting the Stormwater regulations. CPEES has performed stormwater
calculations for a 25-yr, 24-hr rain event for 0.51 acres and approximately 10,738 cubic feet
(cft) of runoff capacity is required to hold the designed rain event. The runoff volume and
weir design calculations are provided in Attachment A.
Please note, during a rain event, no plant operations will be conducted. Therefore, no
washwater is accounted for in the proposed recycle system design when 25-yr, 24-hr rain
event for stormwater is considered.

5.0 STORMWATER / PROCESS WASHWATER RECYCLE SYSTEM
DESIGN AND CONSTRUCTION DETAILS
The proposed recycle system is designed to capture all process washwater and stormwater
from a 25-yr, 24-hr rainfall event from the subject plant wash areas. The recycle system is
designed to hold entire runoff amount from the designed storm event. The approximate
drainage area involved in the process washwater is estimated to be 0.51 acres (Figure 3). The
25 year, 24-hr runoff volume from this drainage area is estimated to be 10,738 cft. A recycle
system designed for the estimated runoff is a four pit system with a drying bed for the waste
materials removed from the pit (Figure 3). The total volume of all the three pits were
designed to be sufficient to hold the entire 25 year, 24-hr run off volume. Please note KERR
strives very hard to control and mitigate migration of any contaminated stormwater from the
facility to the waters of US. rAppropriate�slo es/bertnslwalls,are propose :to=i� so ate:the:0 5
All the four pits in the recycling system are sloped at the entrance in order for a front-end
loader to go into the pit for a periodic cleanup. However, a beam.or-a=siopomway-romthe=pit

shown on Figure 4.
CPEES designed a pit sludge storage area next to the truck washing operations in order to
control stormwater flow that is in contact with the pit sludge. The slopes.of the truck washing
operations and the pit sludge storage area are directed toward the first pit of the four pit
recycling system in order to control and mitigate migration of stormwater contamination from
the washing operations.
The location of the recycling system along with stormwater flow directions and wash areas are
displayed on Figure 3. The construction details for the recycling system are displayed on
Figure 4. The 25 year, 24-hr stormwater runoff calculations are provided in Table 1 of this
report.
A sump pump with a level switch will be provided to pump water from the fourth pit as
required either to the plant or to the truck washing operations. This would help empty'the
third pit to accommodate any possible rain event.
6.0 A to C CONSTRUCTION PERMIT APPLICATION
Based on our consultants' discussions with the State DWQ, it is our understanding that we
need to file a NCG 140000 Notice of Intent (NOI) Form to obtain A to C Permit to construct
the proposed process washwater / stormwater recycle system at the Lenoir Plant. A copy of
the NCG 140000 NOI is attached with the A to C Report for an approval.

NOTE: The designer must use judgment to select the appropriate C value
within the range for the appropriate
land use. Generally, larger
areas with
permeable soils, flat slopes, and dense vegetation should have lowest C
values. Smaller areas with slowly
permeable soils, steep slopes, and
sparse vegetation should
be assigned highest C values.

The overland flow portion of flow time may be determined from Figure 8.03a.
The flow time (in minutes) in the channel can be estimated by calculating the
average velocity in feet per minute and dividing the length (in feet) by the
average velocity.
Step 4. Determine the rainfall intensity, frequency, and duration (Figures 8.03b
through 8.03g—source: North Carolina State Highway Commission; Jan.
1973). Select the chart for the locality closest to your location. Enter the
"duration" axis of the chart with the calculated time of concentration, Tc. Move
vertically until you intersect the curve of the appropriate design storm, then
move horizontally to read the rainfall intensity factor, i, in inches per hour.
Step 5. Determine peals discharge, Q (f?/sec), by multiplying the previously
determined factors using the rational formula (Sample Problem 8.03a).

Note:
Use nomograph Tc for natural basins with well-defined channels, for overland
flow on bare earth, and for mowed -grass roadside channels.
For overland flow, grassed surfaces, multiply Tc by 2.
For overland flow, concrete or asphalt surfaces, multiply Tc by 0.4.
For concrete channels, multiply Tc by 0.2.

To obtain runoff depths
for CN's and other rainfall amounts not shown
in this table, use an arithmetic interpolation.
The volume of runoff from the site can be calculated by multiplying the
area of the site by the runoff depth.
Step 4. Determine the peak rate of runoff for the design storm by adjusting for
watershed shape as follows:
a. Determine an "equivalent drainage area" from the hydraulic length of the
watershed using Figure 8.03n. Hydraulic length is the length of the flow
path from the most remote point in the watershed to the point of discharge.
b. Determine the discharge (cfs/inch of runoff) for the equivalent drainage
area from Figure 8.03o through 8 03q:
Figure 8.03o - for average watershed slopes 0-3%
Figure 8.03p - for average watershed slopes 3-7%
Figure 8.03q - for average watershed slopes 8-50%
Calculate the peak discharge, Q1, of the equivalent watershed by multi-
plying equivalent watershed area by runoff from Table 8.03c in Step 3b.
