Dear Mr. Scavone:
Dee Freeman
Secretary
Enclosed please find a copy of the Compliance Evaluation Inspection Report for the inspection conducted at the
subject facility on July 22, 2009 by Ms. Donna Hood and 1\4s. Marcia Allocco of this Office.
The facility site modifications observed at the time of the inspection had eliminated the discharge of exposed
stormwater to Outfall 001. All exposed stormwater had been re-routed to the recycle pond. Please be advised that
site modifications in the future that allow exposed stormwater to discharge into the floodplain through Outfall 001
and/or any current or newly constructed outfall will require a modification to the Certificate of Coverage.
The recycle pond had been modified between the inspection performed in November /December 2008 and
July 2009. No authorization to construct (ATC) had been issued prior to wastewater recycle pond
modification. Please be advised, per 15A NCAC 2H .0106, that recycle system modifications must receive an
ATC prior to construction. Please send in as -built plans showing all demensions, associated appurtunances,
inlets, and outlets by November'l, 2009. In responding, please address your comments to the attention of
Ms. Marcia Allocco.

The previous inspections, performed on November 20, 2008 and December 9, 2008, revealed exposure
of Outfall 001 to stormwater runoff contaminated by the industrial process at the facility as well as the
presence of additional stormwater outfalls. The inspection was issued as Notice of Violation (NOV)
2009-PC-0095 due to the conditions found on site at the time of those inspections. NOV-2009-PC-0095
required the permittee to apply to NC DWQ Stormwater Permitting for permit modification as well as
remediation of the areas affected by the contaminated stormwater. As a response to NOV-2009-PC-
0095, the permittee made major site modifications, clean-up, and requested a follow-up inspection.
The follow-up inspection was performed on 07.22.2009. Specifically addressing the permittee's NOV
response received 03.23.2009 are the following comments as well as conditions found on the day of the
inspection:
i. Waste Concrete observed at Outfall 001
a) Conditions on the day of the inspection: The waste concrete solids had been removed and the
area's stability significantly improved. The entire length of pipe had been cleaned starting at the
drop inlet where solids from truck washout entered the stormwater system to the discharge
point in the flood plain.
b) Reply to the NOV response: Please be advised that the permittee, in this case, Southern
Equipment Company, Inc. (Ready Mixed Concrete Company) is ultimately responsible for the
site and any associated operator activities
2. Point Source Discharge from Outfall 001
a) Conditions on the day of the inspection: All other outfalls (003, 004, and 005) had been
removed at the time of the follow-up inspection. Truck washout now discharges to the
wastewater recycle system. Outfall 001 is not currently exposed to stormwater runoff
contaminated by the industrial activity. Major site modifications have rerouted stormwater
with industrial exposure into the recycle pond.
b) Reply to the NOV response: Please be advised that if current conditions at the site are modified
and stormwater exposed to the industrial process is allowed to discharge through a discrete
conveyance into the flood plain the Division will require modification of the CoC to include
stormwater monitoring.
c) As response to Outfall 002 not being a voint source: Whether flow from this outfall sheet flows
or is confined to a discrete conveyance is irrelevant. Flow from this outfall is a wastewater. It is
also irrelevant that flow entering this pond is comingled with stormwater_ Comingling with
stormwater does not make this a stormwater pond. There has been a basic misunderstanding
of the difference between stormwater and wastewater in regards to this outfall. No wastewater
is allowed to discharge without a permit regardless of whether it sheet flows or follows a
discrete conveyance per North Carolina General Statute (G.S.) 143-215.1.

3. Implementation of the SPPP
a) Conditions on the day of the inspection: The facility has begun implementation of the SPPP.
The last outfall inspection was performed on 3.20.2009.
b) Reply to the NOV response: This is required regardless of the presence of a stormwater outfall
exposed to the industrial process. it is part of the basic permit text in Part II Section A 8.

NCG140348_NOVresp_response20090504.doc
Hi Donna,
It's finally Friday of what's been a really long week for me, and it was only four days!
Do you still have the draft reseponse to the NOV Response that I wrote up for the Hebron site? (Apr 13, 2009 -
attached) I'm looking back at that. It sounds to me like you confirmed Outfall 001 no longer receives SW associated
with industrial activity (although why they went around their elbow to get to their thumb on that one I'll never
understand.) So I guess they don't need their COC modified if they don't discharge SW, but you could always take the
opportunity to remind them that if they ever discharge SW associated with industrial activity at this site, they will be in
violation of the conditions of coverage of the COC under this GP NCG14. For now, I'd say that's where we have to leave
it.
Sounds like they're implementing their SPPP, which they still need to do as part of the permit they are covered under.
Great.
Under the second bullet in that write-up, we pointed out they never applied for an ATC. Sounds like they modified the
treatment system without applying. Point out the information on the back of the Technical Bulletin that directs them to
do this (I think it cites the rule requirements as well). [As a side note, I still have my concerns that we should allow any
of these places just dig unlined pits for this kind of thing, but I'm not sure what APS has to say about it. Something we
plan to look more into for renewal in a couple of years.] Notice them of Violation there as you and NPSCOA see fit.
As to their third assertion about sheet flow: I still stand behind what I wrote there. I explained that to them in the
beginning when they thought they didn't need any kind of permit.
At the end, in the summary, the second bullet talks about Outfall 002 being subject to WW monitoring per the
conditions of the permit. I would maybe qualify that with "in the event of discharge and in accordance with the
conditions of the permit." I say that because (1) the permit acknowledges that we should not see routine discharges
from a closed -loop recycle system and (2) the permit also says " If the recycle system only discharges in response to a
10-yr 24-hr precipitation event, no monitoring is required." What does all that have to do with their statement?
Basically, if the discharge dissipates as sheet flow, we're presuming that it's a rare occurrence that it discharges anyway
and is probably not subject to sampling when it does. However, if it is subject to sampling, they are not excused just
because it's sheet flow of a wastewater. They either (1) sample according to the permit, or (2) figure out another permit
to get that allows them to dispose of wastewater.
Maybe they just don't understand the permit requirements clearly in that respect.
Hopefully this will help you wrap things up for now at this site. Sounds like they don't necessarily need to modify their
COC (though good to remind the them they should be inspecting visually to assure no wastewater is going
anywhere it shouldn't), but they should have gotten an ATC for the mods they made to the treatment/recycle system.
If it helps to talk more about it, just give me a call. They've made this hard for everybody, really. If RM Concrete Co
wanted to relieve themselves of SW NPDES obligations at Hebron under the argument of no SW discharges, but still
wanted to operate a recycle system, they should have pursued a non -discharge permit from LAU (which they aren't

their proximity to the floodplain, we could argue that overflows from that system do have the potential to reach surface

Donna,
I'll get back to you later this week - I'm up at Water Quality Committee for a presentation tomorrow and will be tied up
with that and EMC the next two days, I will go back and look, and then get back to you hopefully by Friday. I remember
that they did extensive modifications to the treatment system without an RTC, which they should have applied for first,
but that's the only place I remember leaving off when we talked. They may not have any SW outfalls to monitor per se
now (did they ever fix that problem of the solids drying bed at the back corner?), but if they're doing qualitative anyway,
then great. They are still subject to the SPPP all the same because they're under NCG14 in some form or fashion, so glad
to hear they're implementing.
Will try to refresh my memory bank more by the end of the week!

Bethany,
With the entire reworking of the Hebron site, where do we sit with allowing them to keep things the way they are? They
have implemented the SPPP and started qualitative monitoring. (doing everything in the permit, without actually having
it?) The outfall in question is only exposed to normal parking lot runoff now. I am issuing the inspection ( finally) and
don't really know if we can tow the line here. Thoughts?

Dear Ms. Allocco,
In response to the above referenced Notice of Violation:CD
Q,
I,
1. Waste Concrete observed at outfall.001. it
Upon our inspection and remediation of outfall "001" we found
evidence of silt, gravel and mud discharging at outfall 001. The
chunks of concrete observed in your photos appear to be remnants
from the former operator of the site. Nevertheless, we still recognize
this as a problem. In response to this issue, the existing truck parking
area has been moved as indicated on the enclosed site plan. The area
above drain "A" has been isolated from all truck traffic and industrial
activity by rerouting all truck traffic to the upper gate (shown on site
plan). These steps should effectively route all wastewater and storm
water associated with industrial activities to the recycle pond and
significantly reduce the amount of fines discharging out outfall 001.
2. Point source discharge from outfall "001"
We have eliminated the potential point source discharges at outfalls
003, 004 and 005 by removing pipes and/or implementing measures to

f

allow all water to enter recycle pond. The pipe identified in the
conveyer tunnel has always discharged into the recycle pond. We
disagree that a point source discharge occurs at Outfall 002. It is still
our contention that any overflow from the recycle pond dissipates as
sheet flow. Although in your judgment there is a potential for a point
source discharge at Outfall 001, we have eliminated the area
discharging to this outfall from our industrial process, thereby
eliminating storm water that impinges on industrial activities from this
discharge.
3. implementation of the SPPP
Although we may have been deficient in some areas, we disagree that
we had not implemented our SPPP. It is our plan to have an updated
site map for the facility and the SPPP signed by a corporate official no
later than the end of March. We will also conduct the required
stormwater training before the end of the year. Since there are no
point source discharges that discharge wastewaters or stormwater
associated with industrial activities off site, evaluation of outfalls for
non stormwater discharges and qualitative monitoring are not
necessary. However, we will carefully monitor these areas in the event
something changes.
In summary, with the steps outlined above we do not feel that a
modification to our COC is necessary. We appreciate your assistance
with this matter. Please do not hesitate to contact me with any questions.

Dear Mr. Scavone:
Dee Freeman
Secretary
Enclosed please find a copy of the Compliance Evaluation Inspection Report for the inspection conducted at the
subject facility on November 20, 2008 and December 9. 2008 by ivls. Donna Hood and Ms. ivlarcia Allocco of this
Office.
On both days of the inspection, waste concrete was observed at Outfall 001 and for a distance of approximately
150 feet into the floodplain of Kings Branch (please see enclosed map). Therefore, the discharges being conveyed
from the site are deemed as potential point source discharges, and a permit for both stormwater and wate-,vater
discharges is necessarv. Evidence of a discrete conveyance of stormwater from the outfall was observed both
days, as well.
Because point source discharges of stormwater are not authorized in this facility's current Certificate of
Coverage (COC), you must submit a request for modification of your COC to include stormwater, as referenced in
the COC cover letter dated April 11. 2008. You must apply to the Stormwater Permitting Unit for a
modification to the COC by March 13, 2009.
We recognize that a site visit by our office in 2006 concluded that there were not likely point source discharges
of stormwater from the edge of the property or directly into surface waters. However, observations during Our
inspections last Year clearly showed this facility requires an NPDES permit for both hpes of discharges. This
means that all parts of General Permit NCG140000 are applicable, including stormwater monitoring.

Permit: NCG140348 Owner - facility: Southern Equipment Company Inc
Inspection Date: 12/09/2008 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
On November 20, 2008 a compliance inspection was performed at 325 E. Hebron Street facility to determine its eligibility
for no exposure. During the facility site review, wastewater was found in Outfall 001 and had made a discrete
.conveyance through the floodplain. (please see enclosed pictures and map) The wastewater had been allowed to
discharge through the stormwater outfall without proper treatment or monitoring as required by NCG140348. As a result
of improper treatment, approximately 6° of concrete solids accumulated at the outfall, with solids being found
approximately 150' from the outfall. The facility had a stormwater pollution prevention plan, dated 6.09.2008, but had not
implemented it. In addition to the plan not being implemented, it was missing the following items:
1. Signature of the SPPP by a Corporate Officer
2._Mapofall outfall locations
3. Evaluation of stormwater outfalls__ for_non_�stormwater�__ discharges
4. No employee training provided or documented
5. No qualitative monitoring
On December 9, 2008, a follow-up inspection was performed and the same discharge of concrete solids was observed
at Outfall 001.
During this inspection other outfalls with exposure to wastewater were observed.
1. Outfall 005 (Pipe at the concrete sludge drying pad)
2. Pipe in the bottom of the pit with the conveyor belt
3. Outfalls 003 and 004 (corrugated pipes receiving runnoff from the production area)
Neither Outfall 002 (which receives overflow from the recycle pond) nor Outfall 001 (stormwater pipe receiving wastewater
flow) were included in the aboe list. All outfalls are to be visually monitored twice a year with the first monitoring occuring
concurrently with the first sampling event as stated in Part II Section F. No monitoring has been done at any outfall. All
outfalls receiving wastewater should monitored and meet limits according to permit requirements stated in Part II Section
C. Accumulation of waste concrete being discharged into a stormwater conveyance was also observed on 12.09.2008.
(please see enclosed pictures and map) This is prohibited on page one of the permit.

Good Morning Bethany,
I am glad to put this matter behind us and thank you for your hard work in dealing
with these two sites (It pays finally). I am most happy with this paragraph below

for a job well done!! We have no additional comments for the issuance of these two
permits. Good Day

Samar,
I received add. info. from consultant Darin McClure on both the Reams Rd and
Hebron St Ready Mixed Concrete Plants this week. We now have a good picture of
what is on the ground at these sites (I think they did an excellent job pulling
together a description and schematic), and I'm moving ahead with the COCs to wrap
these up.
I'm attaching the COCs and cover letters as well. If you're okay with them, I'll
schedule issuance for this Friday.
Thanks for all your help with this!

Dear Ms. Georgoulias:
As discussed in our phone conversation on February 28, 2008, Mid -Atlantic submits, for
each of the facilities listed above, a site drawing and a schematic drawing of the
recycling system.
On March 10, 2008, Mid -Atlantic met with Rick Alexander of Ready Mixed Concrete to
gather information for the preparation of a Stormwater Pollution Prevention Plan and to
construct a schematic drawing of the recycling system. The results of our site visits are
summarized below and are based on field observations and information provided by Mr.
Alexander.
East Hebron Street Facility
■ Stormwater and process water flows into a settling pond and is then recycled in
the production of concrete. A portion of the truck parking area and employee
parking area flows into a storm drain which discharges into a wooded area.
■ The settling pond shape is semi -oval with the circumference measuring
approximately 275 feet. It is sloping at an approximate 2 to 1 slope with a flat
bottom at a depth of 18' below land surface. The maximum storage capacity of
the pond is approximately 638,000 gallons.

Water entering the settling pond is first collected in a detention pit (measuring
25' x 12' and sloping to a depth of 22.5"). Water is drained from the detention
pit through a weir into the settling pond. Water is piped via a 2 inch pipe using a
7.5 horse power electric pump underground to a 1,200-gallon holding tank,
which is gravity fed into a water scale hopper and loaded directly into trucks.
■ If this pond were to overflow it would discharge into a wooded area. Based on
our visual observations, it appears the water would then dissipate and
discharge off the property as sheet flow.

■ Stormwater and process water flowing into the settling pond is recycled in the
production of concrete.
■ The settling pond shape is semi -oval with the circumference measuring
approximately 247 feet. It is sloping at an approximate 2 to 1 slope with a flat
bottom at a depth of 20' below land surface. The maximum storage capacity of
the pond is approximately 546,000 gallons.
Water is piped via a 3 inch pipe using a double diaphragm pump underground
to a 600-gallon water tank, located in the first loading area, which directly loads
to concrete trucks. The water is also piped to a series of three ASTs (one
4,000-gallon AST and two 10,000-gallon ASTs) that are piped together for a
total storage capacity of 24,000 gallons. Water is pumped from these tanks to
the truck wash areas and into the building (to be heated by the boiler) and then
to the second loading area.
• In the event the settling pond were to overflow, it appears that water would
discharge into the stream which originates (by a spring) on the property and
would discharge at the property boundary as a point source discharge.

Subject: NPDES Stormwater General Permit
Additional Information Request
NCG140348 COC — Hebron Street Plant
Mecklenburg County
Dear Mr. Alexander:
On February 28, 2006, The Division of Water Quality's Stormwater Permitting Unit received a request
for a site visit from the Mooresville Regional Office (MRO) to evaluate the presence of a point source
discharge at this site. After conferring with Mr. Samar Bou-Ghazale of the MRO, the Division is
requesting additional information to proceed with the appropriate permitting action.
After a site visit and discussions with the Central Office, MRO staff concluded that the stormwater
discharge from this site would not be considered a point source discharge as it leaves the property. This
means an NPDES permit to discharge stormwater may not be applicable to this site. However, because
a wastewater treatment system is being operated at this facility, a permit is still required.
North Carolina General Statute § 143.215. I (a)(2) stipulates that a permit is required to construct or
operate any treatment works. That means that at a minimum, an authorization to operate (ATO) the
existing wastewater system is required. Furthermore, the recycle system at this site does not meet
criteria to be permitted by rule under the Non -Discharge rules for closed -loop recycle systems (found in
15A NCAC 2T .1000) and therefore requires some kind of permit.
This facility has two permitting options: (1) either a modification to the Certificate of Coverage (COC)
for this site to include an authorization to operate a wastewater treatment/recycle system and discharge
wastewater (in the event of overflow) must be approved, or (2) a separate Non -Discharge permit from
the Aquifer Protection Section to operate this recycle system is required. The Stormwater Permitting
Unit would only rescind COC No. NCG 140348 once all other appropriate permits are finalized.
Information about the Non -Discharge application and permitting process is available on-line from the
Land Application Unit in the Aquifer Protection Section: http,.Hh2o.erLr.state.nc.us/lau/main.html
In a letter to you dated November 30, 2005, Ms. Aisha Lau of the Stormwater Permitting Unit requested
plans and calculations to demonstrate the washout pit capacity. No plans or design calculations were
ever submitted to demonstrate the pit discharges only in response to storms greater than the 25-year, 24-
hour storm event. We are unable to sufficiently process a modification to the COC without information
about the design basis of this system.

Additional Information Request
January 28, 2008
Since October 2005, the Notice of Intent (NOI) Form for NCG140000 (which is also an ATC or ATO
request for existing facilities) has specified review criteria for recycle systems. A copy of the current
version of this form is, attached for your reference. An application may be considered complete if
calculations demonstrate the capacity of a recycle system to contain the 25-year, 24-hour storm plus one
foot of freeboard. Please understand that demonstrating a recycle system is designed for these
conditions is not a basis for exemption from a permit. In fact, consider that periods of chronic rainfall
(two successive two-year storms, for example) may bring the same volume of water in some areas, if not
more, into the system.
Please notify us of your intention to either (1) modify the NCG140348 COC to include an ATO and
authorization for wastewater discharge or (2) pursue a separate Non -Discharge permit from the Aquifer
Protection Section of DWQ no later than February 29, 2008. If you choose to modify your current
COC for NCG140000, please submit plans and calculations sealed and dated by a P.E. that demonstrate
compliance with effluent limits or sufficient capacity to hold the 25-year storm with a foot of freeboard,
including a water balance with all assumptions, as well as a management plan for solids accumulation.
Please refer to the enclosed NCG140000 NOI form for help in submitting a complete request for
modification and reference your current NPDES permit number. If you have any questions or would
like to discuss this matter further, please contact me at [phone], extension 529.

Mr. Tart,
Attached are two additional information letters that should go out in the mail
today. I noticed from the file you were copied on previous correspondence, so I have
copied you on these as well. I understand from the Mooresville Region that one of
these sites may not have a point source discharge of stormwater, but that the other
does. However, both sites have wastewater treatment facilities that must be
permitted (regardless of whether they discharge). There seems to have been some
confusion in the past about these sites not needing a permit at all. The letters
clarify permitting requirements and explain the additional information that is needed
to conclude action. If you have any questions, please let me or my supervisor
Bradley Bennett know.
Regards,
Bethany Georgoulias

Bradley,
I am attaching 3 pictures for the above site. storm water discharge
from the site will qualify for sheet flow discharge. 1 walked
downstream of the discharge and there are no evidence of any
concentrated flow. Also, the area downstream is vegetated and almost flat.
Please let me know if you need any additional info.
I will send pictures and comments regarding NCG140349 in a different e-mail.

Aisha,
I was hoping to complete my letter to you this morning concerning the matters we discussed on the two Ready Mixed
sites yesterday. However, I was unable to get the Engineer letter on Hebron Rd. scanned until this afternoon. As I am
out of the office at NC DMV's office and working on my Blackberry to get this to you, please excuse the briefness of
my text. To reiterate what our intentions are on both the Reames Rd. Plant and the Hebron Rd: Plant, which is the
subject of the attached letter, we would like for the Mooresville DWQ office to schedule a time to meet myself and or
Andy Stankwytch at each site to confirm there is no point source discharge leaving our property. I may be reached by
e-mail or by calling [phone]. At the time this is conffrmed(positive thinking), we would then submit a formal
request from our office, asking to have the original NO[ from Carolina Concrete returned and a status of no SWP
required for both sites. Thank you for help and patience in this matter.
Sincerely,

Carolina Concrete II — Hebron St.
Proposed COC NCG 140348
Mecklenburg County
Dear Mr. Alexander:
The Division received a NOI for the Carolina Concrete II — Hebron St. facility on
December 22, 2004. Due to some back logged permits on my plate I was unable to begin my
review of the application until August 9, 2005.
In September of 2005 I was able to speak to Ms. Sandra Yarbrough, who informed me
that all of the wastewater discharges from the facility drain to a large centralized pit that only
discharges in response to storms larger than the 25 year/ 24 hour storm. I also wrote the COC to
only include stormwater leaving the site, and stated that if wastewater did leave the site the COC
would have to be amended and proper wastewater controls employed.
In order to substantiate the fact that the pit only discharges in response to storms
equal to or greater than the 25 year/ 24 hour storm please send me drawings and
calculations that show this.
It has also come to my attention that the ownership of this facility has changed.
Please complete the enclosed name/ownership change form as well.
Please get this information to my attention by January 13, 2006.
Thank you -for your cooperation, and if you have any questions please call me at

Dear. Andy:
At your request, Mid -Atlantic Associates. P.A. visited the aforementioned site to evaluate
the storm waterlprocess wastewater flow characteristics at the site. As you are aware,
ready mixed concrete facilities which discharge stormwater and/or process wastewater off -
site through point source discharges are required to be covered under the North Carolina
Department of Environment and Natural Resources, Division of Water Quality, General
Permit No. 140000. If the stormwater and/or process wastewater generated at a facility
dissipates and leaves the site as sheet flow, coverage under this permit is not required.
Mr. Kerry Cooper of Mid -Atlantic visited the site on July 12, 2000 while the site was
under construction. Based on our observations, review of the site drawings and
discussions with you, it appears that there will be no paint. source discharges off of the
site once construction is complete and the facility is operational. Although there are
several slope drains an site and the two sediment ponds discharge over broad crested
weirs, there is a large, heavily vegetated and gently sloping buffer zone between these
discharge features and the -property boundary. It appears that the discharge from these
features will dissipate into sheet flow prior to leaving the site.
This determination was made based on the information available and site conditions at the
time of our site visit. If flow characteristics at the site change once operations begin and
result in point source discharges at the property boundaryisi, we recommend that you take
steps to- eliminate the point source discharges or apply for coverage under General Permit
140000. As a precaution, it may be beneficlal to eliminate the slope drains after
construction and route all stormwater and process wastewater to the sediment ponds. We
also recommend you obtain from your design engineer detailed design and construction
drawings/specifications for the sediment ponds in the' event the need arises to apply for
coverage under the general permit.

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any discharge of stormwater associated
with industrial activity that has a point source discharge to the surface waters of the state.
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 .0I00, stating the reasons supporting the request. Any application for an individual
permit should be made at least 180 days 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 Permit be
provided.
Facilities submitting NOIs for coverage under this permit, prior to establishment or approval of a
Total Maximum Daily Load (TA4DL) for a priority pollutant(s) for stormwater discharges (i.e.
wet weather flows), may be covered under this permit during its term. For such facilities
continued coverage under the reissuance of this permit is subject to the facility demonstrating
that it does not have a reasonable potential to violate applicable water quality standards for such
pollutants due to the stormwater discharge(s). For facilities that do have a reasonable potential
for violation of applicable water quality standards due to the stormwater discharge(s) the facility
shall apply for an individual permit 180 days prior to the expiration of this general permit. Once
the individual permit is issued and becomes effective the facility will no longer have coverage
under the general permit. A list of approved TMDLs for the state of North Carolina can be found
at http://h2o.enr.state.ne.us/tmdl/General_TMDLs.htm
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater and/or process wastewater associated with
industrial activity as defined in this permit. Such discharges shall be controlled, limited and
monitored as specified in this permit. Although this permit requires submittal of analytical
monitoring results annually, discharges occurring throughout the year must meet the conditions
and limitations of this permit.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater and 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.
Part I Page I of 2

Permit No. NCG140000
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization or approval.
The discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.
SECTION C: PERMIT RENEWAL
Dischargers covered by general permits need not submit new Notices of Intent or renewal
requests unless so directed by the Division. If the Division chooses not to renew a general
permit, all facilities covered under that general permit shall be notified to submit applications for
individual permits or notified to take other appropriate actions at the discretion of the Director.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this general permit. The Plan shall include, at a minimum,
the following items:
Site Plan. The site plan shall provide a description of the physical facility. 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 accurate latitude and
longitude of the point(s) of discharge.
(b) A list of the potential pollutant sources which may be expected to contribute to
contamination of stormwater discharges .
(c) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(d) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(e) A list of significant spills or leaks of pollutants (see definitions) that have
occurred at the facility during the 3 previous years and any corrective actions
taken to mitigate spill impacts.
(1) 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 III, Standard Conditions, Section
B, Paragraph 5.
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
Part II Page 1 of I I

Permit No. NCG 140000
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 storrwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title IIl of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, -or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices have a
drain, the drain shall be controlled by manually activated valves or other similar
devices, which shall be secured with a locking mechanism. If there is no drain, the
containment shall be observed and pumped out as needed to maintain adequate
capacity. Any stormwater that accumulates in the containment area shall be at a
minimum visually observed for color, foam, outfall staining, and visible sheens,
prior to release of the accumulated stormwater. Accumulated stormwater shall be
released if found to be uncontaminated by the material stored within the
containment area. 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 narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. 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, a SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
Part I1 Page 2 of 11

Permit No. NCG 140000
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training provided for all
employees at a minimum on an annual basis on proper spill response and cleanup
procedures and preventative maintenance activities for all personnel involved in any of
the facility's operations. Facility personnel (or team) responsible for implementing the
training shall be identified.
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 Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan 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. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. Revision dates should
be included on the pages changed.
The Director, or his designee, may notify the permittee when the Plan does not meet one
or more of the minimum requirements of the permit. Within 34 days of such notice, the
permittee shall submit a time schedule to the Director, or his designee, for modifying the
Plan to meet minimum requirements. The permittee shall provide certification in writing
(in accordance with Part III, Standard Conditions, Section B, Paragraph 5) to the Director,
or his designee, that the changes have been made.
$. Facility Inspection Program. Facilities are required to inspect all BMP's and stormwater
systems on at least a semiannual schedule, once in the fall (September -November) and
once during the spring (April - June). The inspection and any subsequent maintenance
activities performed shall be documented, recording date and time of inspection,
individual(s) making the inspection, and any comments. Records of these inspections
shall be incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the

SECTION B: ANALYTICAL MONITORING REQUIREMENTS - STORMWATER
DISCHARGE
I . Storrnwater associated with industrial activity that is not combined with process
wastewater
During the period beginning on the effective date of the permit and lasting until
expiration, the Permittee is authorized to discharge stormwater associated with industrial
activity that is not combined with process wastewater subject to the provisions of this
permit. Analytical monitoring of stormwater discharges shall be performed as specified
below in Table 1.
For each parameter, the arithmetic mean of all analytical sampling results collected
during the term of the permit shall be calculated for each individual outfall. The
computed arithmetic mean is then compared to the cut-off concentrations listed below in
Table 2. If the arithmetic mean is less than the specified cut-off concentration for a given
parameter, then the facility is not required to continue annual analytical monitoring for
that parameter (at that outfall) during the remaining term of the permit unless a significant
change in facility operations or configuration occurs. If a cut-off concentration results in
discontinued analytical monitoring at an individual discharge outfall, the permittee is
required to maintain facility operations that ensure the continuation of stormwater runoff
quality.
The nermittee must perform analvtical samolina of stormwater discharges during the first
and last Year of the vermit coverage regardless of cut-off concentration conditions.
Analytical results from sampling during the final year of the permit coverage must be
submitted with the permit renewal application. All analytical monitoring shall be
performed during a representative storm event.

Facilities which have any vehicle maintenance activity occurring on -site which uses more
than 55 gallons of new motor oil per month when averaged over the calendar year shall
perform analytical monitoring as specified below in Table 3. This monitoring shall be
performed at all outfalls which discharge stormwater runoff from the vehicle maintenance
areas.
For each parameter, the arithmetic mean of all analytical sampling results collected
during the coverage of the permit shall be calculated for each individual outfall. The
computed arithmetic mean is then compared to the cut-off concentrations listed below in
Table 4. If the arithmetic mean is less than the specified cut-off concentration for a given
parameter, then the facility is not required to continue annual analytical monitoring for

SECTION C. ANALYTICAL MONITORING REQUIREMENTS - PROCESS
WASTEWATER
This general permit authorizes the discharge of process wastewater associated with four distinct
activities: 1) Vehicle and equipment cleaning - external surfaces; 2) Overflow from recycle
systems that receive stormwater runoff; 3) Wetting of raw material stockpiles; 4) Mixing drum
cleaning. Discharge of process wastewater generated by any other activity is not authorized
under this permit. In the event that authorized process wastewaters commingle prior to
discharge, sampling the combined discharge will meet the conditions of this permit for those
separate activities, with respect to the annual sample. In the case of commingled process
wastewater, the most stringent of the applicable limits will apply.
Note: 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.
Process Wastewater Associated with Vehicle and Equipment Cleaning
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.
If detergents are used, they must be biodegradable and the pH adjusted to 6 to 9 standard units.
With or without the use of detergents, wastewater released to the waters of the State must meet
the requirements of Table 5
Analytical monitoring of process wastewater associated with vehicle and equipment cleaning
discharges shall be performed as specified below in Table 5. Annual analytical monitoring shall
be performed during a process wastewater discharge event associated with vehicle and
equipment cleaning.
