NC DENR Raleigh Regional office
In response to your letter dated February 17, 2016 and the associated site inspection, the following addresses the concerns
that you listed.
Item #1. USGS general location maps were added to the SPPP Plan for all our locations on or about December 7, 2015, In
addition, we reviewed and updated the spill prevention and response plan, the preventative maintenance & good
housekeeping plan and added a site specific Environmental Manual for each of our sites
Item #2. We are in the process of expanding the number of trained personnel in the proper storm water collecting
procedures per the permit requirements. This will better allow us to collect a sample during a qualified rain event.
Item #3. We are in the process of retrieving the RAP from below the retaining wall and expect it will be complete by the end
of April. None of the RAP is off of Sunrock property. We have also retrained our employees on proper stockpiling
techniques to ensure this does not happen again.
Please contact us if you need further information or if this does not meet your requirements.
Sincerely,
Carolina Sunrock, LLC

right onto Ebenezer Church Road (at CarMax). Travel another % mile and turn left on Barefoot Industrial Road; the
facility will be ahead, directly before the road bears left. There are 'DO NOT ENTER' signs on both sides of the
gate; however, this is the correct entrance. The other entrance has tire spikes which will not pierce large truck tires
but may damage the state vehicle tires.
(II) FACILITY DESCRIPTION: Carolina Sunrock Corporation operates'a facility that produces batch mixed
asphalt, truck mixed concrete, and crushed stone from old concrete. Each part of the operation has its own manager
who is responsible for his own records. The crushing operation at the site does not require a permit and is
considered temporary and mobile:; _. .
(III) SPECIAL SAFETY NEEDS: Standard Safety Equipment. Recommended PPE includes hard hat, safety
glasses, steel toed boots and hearing protection..
(IV) INSPECTION SUMMARY: On December 3, 2015, I, Maureen Conner along with Ray Williams (DWM)
and Cory Larsen (DWR) as part of multimedia pilot inspection program,,conducted an inspection at Carolina
Sunrock, LLC- RDU distribution center. I did not observe any odor off site, nor any fugitive dust during the site
visit. Neither the facility or DAQ has received any complaints against the facility in the last year. We meet with,the
Plant Supervisor, Mike Heitzman and Tony Sample, Compliance Manager for the inspection. We reviewed the
permit conditions and recordkeeping. They took us on a tour of the asphalt and concrete plant; both were operating

NCG 140000 General Permit for Ready -Mixed Concrete
Wake County
Dear Mr. Pohl:
Staff from the Department of Environmental Quality (DEQ) conducted a stormwater compliance
inspection on December 3, 2015 for permit no. NCG140251 as part of a multimedia inspection of the
subject facility. We appreciate the assistance provided by Tony Sample and other plant personnel during
the inspection. Please reference the attached inspection report checklist and summary in addition to the
comments provided below.
The facility appeared reasonably well -managed and a stormwater management 'program has been
implemented; however, a number of items do require your attention to achieve full compliance as follows:
The stormwater pollution prevention plan (SPPP) was available electronically but was found to
be missing items such as a USGS general location map, a spill prevention and response plan, and
a preventative maintenance & good housekeeping plan, as required by Part III of the permit.
Please update the SPPP to include these items immediately.
2. This facility is required to monitor combined wastewater and stormwater discharges from the
detention basin on a quarterly basis but has performed qualitative and analytical monitoring only
once since 2014 citing difficulty with the permit requirement of a 72-hour period separating
measurable storm events. At the time of inspection, no freeboard was observed indicating a
recent discharge which likely could have been sampled for'analytical parameters. DEQ fully
expects that greater efforts will be made to sample in accordance with the permit -required
monitoring program. Please note that continued inaction will result in future compliance and
enforcement actions.
3. Inspectors observed rap spilling over the containment wall and offsite into surface water buffers
in a couple areas adjacent to the detention basin. This material must be removed immediately and
maintained onsite as discussed with your personnel.

Inspection Date: 12f03/2015 Inspection Type : Compliance Evaluation Reason for Visit Routine
Inspection Summary: I- .
A multi -media program compliance inspection was conducted by staff from the Division of Water Resources, Air Quality,
and Waste Management on December 3 2015 to evaluate compliance with NPDES stormwater and air quality permits
issued to the facility. The stormwater inspection results for NCG140251 are presented below.
The stormwater pollution prevention plan (SPPP) was reviewed electronically and contained most components, and appears - -
accurate, however a few items were missing including a USGS general location map, spill prevention and response plan,
and a preventative maintenance and good housekeeping plan, as required by Part III of the permit.
The facility has one outfall location in the southwest corner of the property and discharge occurs from a concrete detention
basin designed to treat combined stormwater and wastewater flows. No freeboard was observed at the time of inspection
indicating a recent discharge event. Water levels are managed during summer months through the use of treated effluent as
makeup process water (concrete batching). pH control (CO2 bubbler) was present and read 7.46 units. The facility has -
performed qualitative and analytical monitoring only once since 2014 but cited difficulty with the permit re4quirement of a
period of at least 72 hours separating measurable storm events and has petitioned for a change to the permit at renewal.
Division staff instructed the permittee's representative to make greater efforts in meeting current monitoring program. -
Secondary containment is provided where necessary, and Vehicle maintenance is not conducted on the property. Overall,
the site is reasonably well -managed from a stormwater perspective. Some areas adjacent to the detention basin were
observed with rap spilling over the containment wall and offsite into surface water buffers:. This material must be removed
and maintained onsite as discussed:. -

Subject: NPDES Stormwater Compliance Evaluation Inspection
COC Number NCG 160053
ST Wooten— Sims Plant
NCG 160000 General Permit for Asphalt Paving Mixtures and Blocks
Wilson County
Dear Mr. Washburn,
Staff from the Department of Environmental Quality (DEQ) conducted a stormwater compliance
inspection on December 4, 2015 for permit no. NCG160053 as part of a multimedia inspection of the
subject facility. We appreciate the assistance you and other plant personnel provided during the
inspection. Please reference the attached inspection report checklist and summary in addition to the
comments provided below.
The facility was not operating the day of the inspection but appeared reasonably well -managed and a
stormwater management program has been implemented; however, a number of items do require your
attention to achieve full compliance as follows:
1. The stormwater pollution prevention plan (SPPP) was complete based on the presence of all
essential elements but will require revision based on the finding of the inspection and items
below. Update the site plan, stormwater monitoring program, and all other affected SPPP
components as necessary.
2. Walkthrough of the site revealed several massive rap, shingle, and/or waste piles in the southern
half of the property that were not depicted on the SPPP site plan (reference the enclosed aerial
photography). These areas are part of your industrial activity must be added to.the site plan and
maintained under the SPPP. One low-lying area was observed acting as a discrete stormwater
conveyance along the fence line near a shingle pile and is not currently monitored. Unless the
area is regraded and stabilized with vegetation to promote sheet flow off the property, this
stormwater discharge outfall (SDO) location must be monitored for analytical and qualitative
parameters.
3. Two other discharge points (sediment basins) were observed that must be accounted for in the
SPPP. Only two (2) outfall locations have been properly identified and monitored so far out of a
possible five (5). All outfalls must be monitored going forward as discussed during the
inspection. A request for representative outfall status will be considered by DEQ if you wish to
pursue that option.

Inspection Summary:
A multi -media program compliance inspection was conducted by staff from the Division of Water Resources, Air Quality,
and Waste Management on December 4 2015 to evaluate compliance with NPDES stormwater and air quality permits
issued to the facility. The stormwater inspection results. for NCG160053 are presented below:
.P P P (SPPP)
__ -. .. ... .._ .. ..
The stormwater pollution revention Ian SPPP was reviewed and was complete based on the presence of all essential
elements, however, the SPPP will need be revised based on the findings of the site walk-through. A review of analytical
monitoring included one tier 1 response due to 220 mg/L TSS at SDO 2 in 2015. Result from next event was below
benchmark:
The existing site plan does not depict massive rap, shingle, and/or waste piles in the rear of the site. These areas must be
added to the site plan and maintained under the SPPP. One low-lying area was observed acting as an outfall along the
fence line near a shingle pile and is not currently monitored. If not monitored going forward, it may be regraded and
vegetated to promote sheet flow off the property.
Two other sediment basins were observed that appear to discharge and should be added to the SPPP. Division staff
discussed the possibility of representative outfall status (ROS) and explained that the request must be made in writing if,
desired. Only 2 of 4outfall locations have been properly identified and monitored so far. ROS maybe an option otherwise
all outfalls must be monitored going forward. The site appeared reasonably well kept and maintained and was not operating
at the time of inspection.

Dear Mr. Pohl:
Secretary
S. JAY ZIMMERMAN
Staff from the Department of Environmental Quality (DEQ) ,conducted a stormwater, compliance
inspection on December 3, 2015 for permit no. NCG140251 as part of a multimedia inspection of the
subject facility. We appreciate the assistance provided by Tony Sample and other plant personnel during
the inspection. Please reference the attached inspection report checklist and summary in addition to the
comments provided below.
The facility appeared reasonably well -managed and a stormwater management program has been
implemented; however, a number of items do require your attention to achieve full compliance as follows:
1. The stormwater pollution prevention plan (SPPP) was available electronically but was found to
be missing items such as a USGS general location map, a spill prevention and response plan, and
a preventative maintenance & good housekeeping plan, as required by Part III of the permit.
Please update the SPPP to include these items immediately.
2. This facility is required to monitor combined wastewater and stormwater discharges from the
detention basin on a quarterly basis but has performed qualitative and analytical monitoring only
once since 2014 citing difficulty with the permit requirement of a 72-hour period separating
measurable storm events. At the time of inspection, no freeboard was observed indicating a
recent discharge which likely could have been sampled for'analytical parameters. DEQ fully
expects that greater efforts will be made to sample in accordance with the permit -required
monitoring program. Please note that continued inaction will result in future compliance and
enforcement actions.
3. Inspectors observed rap spilling over the containment wall and offsite into surface water buffers
in a couple areas adjacent to the detention basin. This material must be removed immediately and
maintained onsite as discussed with your personnel.

Inspection Summary:
A multi -media program compliance inspection was conducted by staff from the Division of Water Resources, Air Quality,
and Waste Management on December 3 2015 to evaluate compliance with NPDES stormwater and air quality permits
issued to the facility. The stormwater inspection results for NCG140251 are presented below.
The stormwater pollution prevention plan (SPPP) was reviewed electronically and contained most components, and appears
accurate, however a few items were missing including a USGS general location map, spill prevention and response plan,
and a preventative maintenance and good housekeeping plan, as required by Part III of the permit.
The facility has one outfall location in the southwest comer of the property and discharge occurs from a concrete detention
basin designed to treat combined stormwater and wastewater flows. No freeboard was observed at the time of inspection
indicating a recent discharge event. Water levels are managed during summer months through the use of treated effluent as
makeup process water (concrete batching). pH control (CO2 bubbler) was present and read 7.46 units. The facility has
performed qualitative and analytical monitoring only once since 2014 but cited difficulty with the permit re4quirement of a'
period of at least 72 hours separating measurable storm events and has petitioned for a change to the permit at renewal.
Division staff instructed the permittee's representative to make greater efforts in meeting current monitoring program.
Secondary containment is provided where necessary, and Vehicle maintenance is not conducted on the property. Overall,
the site is reasonably well -managed from a stormwater perspective. Some areas adjacent to the detention basin were
nhserved with raD soillina over the containment wall and offsite into surface water buffers. This material must be removed
and maintained onsite as discussed.

Dear Permittee:
Division of Water Quality
Coleen H. Sullins
Director
August 1,2011
Dee Freeman
Secretary
Subject: NPDES Stormwater Permit Coverage Renewal
Raleigh RDU Facility
COC Number NCG140251
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. 1,
• Section 8: The monitoring parameter Oil & Grease has been replaced by the parameter Total Petroleum
Hydrocarbons.
• Sections A, 8 & C: Inability to sample due to adverse weather must be reported in the SPPP.
• Sections A, 8 & 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: 7Q10-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].

PART 1 INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of Water
Quality (DWQ) by the filing of a Notice of Intent (N01) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any point source discharge of stormwater
and/or authorized discharge of process wastewater associated with industrial activity.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H
.0100, stating the reasons supporting the request. Any application for an individual permit should
be made at least 180 days prior to commencement of discharge and must be secured prior to
commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an individual permit but which could be covered by this General Permit may request
that the individual permit be revoked and coverage under this General Permitbe provided.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater discharges is established. A TMDL sets a pollutant
loading limit that affects a watershed, or portion of a watershed, draining to an impaired water.
For stormwater discharges to watersheds affected by a TMDL, coverage under this permit
may depend on the facility demonstrating it does not have reasonable potential to violate
applicable water quality standards for those pollutants as a result of discharges. If the
Division determines that discharges have reasonable potential to cause water quality standard
violations, the facility shall apply for an individual permit 180 days prior to the expiration date of
this General Permit. Once that permit is effective, the permittee will no longer have coverage under
this General Permit. [Note the facility must identify impaired waters (scheduled for TMDL
development) and waters already subject to a TMDL in the Site Plan, as outlined in the Stormwater
Pollution Prevention Plan, in Part III].
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge stormwater and authorized process wastewater associated
with industrial activity. Such discharges shall be controlled, limited, and monitored as specified in
this permit.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires, is modified, or is revoked, the permittee is authorized to discharge
stormwater and authorized process wastewater to the surface waters of North Carolina or separate
storm sewer system which has been adequately treated and managed in accordance with the terms
and conditions of this General Permit. All discharges shall be in accordance with the conditions of
this permit.
The types of authorized discharges are dependent upon DWQ approval and are detailed in the
permittee's individual Certificate of Coverage (COC). Where applicable, the CDC also details DWQ's

pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(a) . A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters, the name
of the receiving water(s) to which the stormwater outfall(s) discharges, or if the discharge is to a
municipal separate storm sewer system, the name of the municipality and the ultimate receiving
waters, and latitude and longitude of the point(s) of discharge. The general location map (or
alternatively the site map) shall identify whether the receiving water is impaired (on the state's
303(d) list of impaired waters) or is located in a watershed for which a TMDL has been
established, and what the parameter(s) of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor process
areas, crushing activities, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge from each outfall. A narrative description of handling and
storage of Fly ash, ash by-products, and recycled materials.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary, the
stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial
activity areas (including storage of materials, spill kits, disposal areas, process areas, loading
and unloading areas, and haul roads), site topography, all drainage features and structures,
drainage areas for each outfall, direction of Flow in each drainage area, industrial activities
occurring in each drainage area, buildings, existing BMPs, and impervious surfaces. The site
map shall include a distance legend and must indicate the percentage of each drainage area that
is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility during the three
(3) previous years and any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The certification statement will be signed in accordance with the
requirements found in Part V, Standard Conditions, Section B, Paragraph S. The permittee shall
re -certify annually that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practical, the permittee shall prevent exposure of all
storage areas, material handling operations, and manufacturing or fueling operations. In areas
where elimination of exposure is not practical, the stormwater management plan shall
document the feasibility of diverting stormwater runoff away from areas of potential
contamination.
Part III Page 1 of 3

Permit No. NCG140000
(b) Secondary Containment Requirements and Records. Secondary containment is required
for: bulk storage of liquid materials, storage in any amount of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, and storage
in any amount of hazardous substances, in order to prevent leaks and spills from contaminating
stormwater runoff. A table or summary of all such tanks and stored materials and their
associated secondary containment areas shall be maintained. If the secondary containment
devices are connected to stormwater conveyance systems, the connection shall be controlled by
manually activated valves or other similar devices (which shall be secured closed with a locking
mechanism), and any stormwater that accumulates in the containment area shall be at a
minimum visually observed for color, foam, outfall staining, visible sheens and dry weather Flow,
prior to release of the accumulated stormwater. Accumulated stormwater shall be released if
found to be uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices
(BMP) shall be provided. The installation and implementation of BMPs shall be based on the
assessment of the potential for sources to contribute significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater discharges. The
BMP Summary shall include a written record of the specific rationale for installation and
implementation of the selected site BMPs. The BMP Summary shall be reviewed and updated
annually.

identified in a written list incorporated into the SPRP, and signed and dated by each individual
acknowledging their responsibilities. A responsible person shall be on site at all times during
facility operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC) may be a
component of the SPRP, but may not be sufficient to completely address the stormwater aspects
of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by
reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and
good housekeeping program shall be developed and implemented. The program shall list all
stormwater control systems, stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including material storage areas, material
handling areas, disposal areas, process areas, cement crushing areas, loading and unloading
areas, ash storage areas, and haul roads), all drainage features and structures, and existing
structural BMPs. The program shall address and maintain a record of the handling and storage
of fly ash, ash by-products, and recycled materials. The program shall establish schedules of
inspections, maintenance, and housekeeping activities of stormwater control systems, as well as
facility equipment, facility areas, and facility systems that present a potential for stormwater
exposure or stormwater pollution. Inspection of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program. Timely compliance with the
established schedules for inspections, maintenance, and housekeeping shall be recorded in
writing and maintained in the SPPP. All such inspections must be documented with printed
name, date and signature of the individual performing the inspection(s).
S. Employee Training. Training programs shall be developed and training provided at least once a
year for facility personnel with responsibilities for: spill response and cleanup, preventative
maintenance activities, and for any of the facility's operations that have the potential to
contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the

Permit No. NCG140000
training shall be identified, and the annual training shall be documented by the signature of each
employee that participates.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and revision
to the SPPP. Responsibilities for all components of the SPPP shall be documented and position
assignments provided. See signatory requirements in Part V Section B.5 of permit.
Plan Amendment The permittee shall amend the SPPP whenever there is a change in design,
construction, operation, or maintenance which has a significant effect on the potential for the
discharge of pollutants to surface waters. All aspects of the Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. The annual update shall
include an updated list of significant spills or leaks of pollutants for the previous three years, or
the notation that no spills have occurred. The annual update shall include written re-
certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. Each annual update shall include a documented re-evaluation of the
effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management Plan. The
annual update shall be documented with the printed name, date and signature of the individual
performing the review, as well as a detailed description of the changes necessary to keep the
SPPP updated.
8. The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit
a time schedule to the Director for modifying the SPPP to meet minimum requirements. The
permittee shall provide certification in writing (in accordance with Part V, Standard Conditions,
Section B, Paragraph 5) to the Director that the changes have been made.
9. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of
the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual
schedule, according to the schedule in Table 2. These inspections shall have at least 30 days
separating inspection dates, unless inspections are required more frequently by DWQ as part of
the Tiered Response. These facility inspections are different from, and in addition to, the
stormwater discharge characteristic monitoring required in Part IV of this permit.
10. Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan.
Implementation of the SPPP shall include documentation of all monitoring, measurements,
inspections, maintenance activities, and training provided to employees, including the log of the
sampling data and of actions taken to implement BMPs associated with the industrial activities,
and including vehicle maintenance activities. Such documentation shall be kept on site for a
period of five (5) years and made available to the Director or the Director's authorized
representative immediately upon request.

This General Permit authorizes the discharge of process wastewater associated with three distinct
activities: 1) vehicle and equipment cleaning- external surfaces, 2) wetting of raw material
stockpiles, and 3) mixing drum cleanout. The authorization to discharge wastewater is specifically
identified on each permittee's COC. Process wastewater discharges generated by any other
activity are not authorized under this permit, except allowable non-stormwater discharges
permitted by 15A NCAC2H.0106(f). Authorized process wastewater commingled with stormwater
shall be considered process wastewater.
1. Process Wastewater Associated with Vehicle and Eauinment Cleanin
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge process wastewater associated with vehicle and equipment
cleaning, subject to the provisions of this permit. For the purposes of this permit, vehicle and
equipment cleaning is limited to the rinsing of the external surfaces of vehicles and equipment.
2. Process Wastewater Associated with Raw Material Stockpiles'
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge process wastewater associated with wetting of raw material
stockpiles, subject to the provisions of this permit.
3. Process Wastewater Associated with Mixing Drum Cleanout
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge process wastewater associated with mixing drum cleanout
subject to the provisions of this permit
All Authorized Process Wastewater Discharges
Analytical monitoring of the above authorized process wastewater discharges shall be performed
as specified in Table 7.
If authorized process wastewaters commingle prior to discharge, sampling the combined discharge
will meet the monitoring requirements of this permit. Sampling shall be performed during
discharge; these events may or may not be associated with rainfall.
Authorized wastewater treatment facilities may include some wastewater recycling as a means of
volume management.
Surface water discharges from authorized wastewater treatment facilities are subject to the
provisions, monitoring requirements, and limits of this permit. Authorized wastewater treatment
facilities with Vq wastewater discharges to surface waters are exempt from the requirements of

Raleigh, NC
Wake County
Dear Mr. Sample:
On December 22, 2005 Myrl Nisely and Ron Boone of the Raleigh Regional Office of Division
of Water Quality made a compliance inspection at Sunrock's RDU facility on Barefoot Industrial
Rd. We greatly appreciated the assistance given by Brian Birdsall and Fred Blankenship. A
follow-up visit was made on January 10, 2006 by Ken Schuster and Myrl Nisely.
At first look, the site appears to be non -discharge regarding process wastewaters, but appe<u's to
have one Stonnwater (SW) outfall. Upon further consideration, both ideas are incorrect, as
discussed below. The asphalt and ready mix plants are integral to each other. so this inspection
covered stornnvater concerns for both. In fact, where a site contains both asphalt and concrete
such as this, only one SW permit is needed. We ask that Sunrock file a request for rescission of
the asphalt permit, NCG 160138
There were a number of improvements needed in the Stormwater Pollution Prevention Plan. The
one SP3 can serve both industrial activities if modifications are made to tables and descriptions
to include all industrial activities. As a result of this inspection, the Division is also requiring a
re -definition of releases from the plant.
The flow of stormwater on the north end of the site is commingled with runoff from the last two
aggregate piles. This mixing causes that release to fall under the wastewater portion of the
permit, so must meet permit limits. The company should investigate a Best Management
Practice (BMP) to improve that release point, perhaps using a retention basin to assure TSS is
below 30 mg/I, assuming pH falls within the 6 to 9 limits.
This site is uniquely designed with the retaining wall along the entire west side, with industrial
activities directing water to a section of the plant located over several feet of aggregate. At first

observation, this arrangement would suggest that no process waters leave the site. However,
water percolates through the surface and emerges from under a layer of stone outside the wall.
Engineering principles suggest that a series of toe drains likely exist in the base of the wall to
relieve the water, but these are covered by uniform aggregate banked against the outside of the
wall. At several places the water travels from the rocks into the weedy area on its way to a
stream channel. Therefore, this facility does have releases of wastewater, albeit attenuated by
the material it must pass through before reaching the stream.
'file Division feels that one of the larger release points, probably in the vicinity of the point
Where the wall bends further to the west, could be chosen as a sample point. The similar release
points along the wall could be handled under representative outfall status. They would not have
to be individually sampled, once that status is established. Regulations require Sunrock to apply
to the Division for representative outfall status by sending a letter of request for our review.
On 1/10/06 during a follow-up visit by DWQ, washdown from the asphalt plant was exiting
through an opening in the curbed section meant to protect the grate From industrial runotl. This
was brought to Nil% Birdsall's attention at the time for immediate corrective action.
Our detailed comments on the Stormwater manual are as follows (also see attached checklist):
1. Part II Section A(1)(a) requires a USGS map zoomed to an appropriate level to show
transportation routes and surface waters. Please add a colored line from your SW outfall to
Where it eventually enters a named stream. Label the stream, i f the map does not make that
clear. Add the latitude and longitude of the outfall where it leaves the property.
2. For Part If Section A(1)(d), the site map, please calculate and note the'yo impervious portion
Of the site. Crushed stone areas are considered impervious, in addition to paved areas.
Clearly identify the SW outfall on the map, as well, assuming a decision is made to continue
its existence rather than funneling that water to the recycle cell area.
3. Part II Section A(l)(e) requires recording significant spills ofany kind. This could not be
located in the manual. Each year the report should note and be initialed if no spills occurred.
4. Part 11 Section A(1)(0 asks for certification (best during a rain) that no process wastewaters
from either the asphalt or the concrete plantjoin with rainwater before exiting the SW outfall.
5. Admixture chemicals and fuel at the concrete facility were inside containment structures.
However, the admixture containment drain valve was open and had no lock.. See Part 11
Section A(2)(b). Improved employee training shoulCI help correct this.
6. A summary of BMPs was absent, Part II Section A(2)(c). Please describe in some cletail how
the drum washout pit and settling cells are used, how large rains are handled, and how water
is recycled or reused. This narrative should describe every BNIP throughout the plant.
Drum washouts take place in a pit surrounded on three sides by concrete blocks. It was not
clear to this observer whether water escaped through cracks between blocks or not. It would
appear that an overflow during heavy rains (or heavy use) would likely move into the water
recycle cells. Please describe in the manual how this BMP can be counted on to keep the

Sumock RN-1 CLI 12/22/05
Pugr i oC+
contents on the site. As observed above, much of this water travels downward thrai1'11 the
surface and to the stream outside the wall
7. A separate Spill Prevention and Response Plan, in addition of the SPCC manual on file,
needs to be written. Describe how contaminated SW will he handled. Part II Section
S. A description of your preventative maintenance program (to avoid broken hydraulic oil lines,
for example) and general housekeeping should be added, Part II Section A(4).
9. The Division has not received annual analytical data since the Sunrock takeover from Blaloc.
In light of the discussion above, a sample point for process wastewater traveling fi-om the
retaining wall should be established as one outfall. The outfall that has so far been
considered the Stonnwater outfall is to be sampled annually as a process wastewater as well,
because of the high load of silt washed down the asphalt drive and from the aggregate piles
nearby. See the permit for details about parameters to be tested at these two outfalls.
A follow-up visit will be made in March to see the above revisions to the SP3 manual Please
submit a request for rescission of permit NCG 160133 right away. Please also send a request for
representative outfall status for releases along the wall.
