ADDENDUM
The National Pollutant Discharge Elimination System (NPDES) program was established under the federal
Clean Water Act and then delegated to the Division of Water Quality for implementation in North Carolina. The
NPDES permitting program for stormwater discharges was established in 1990. Phase I focuses on site and
operations planning to reduce pollutant sources.
Through the NPDES permitting program industrial facilities that fall into one of the subject ten categories are
required to obtain permit coverage under a general permit or an individual permit, depending upon the
facilities SIC code and the industrial activity occurring at the facility. There are currently 19 active general
stormwater permits in North Carolina. One condition that is applicable to both the general permits and
individual stormwater permits is the requirement to develop and implement site -specific comprehensive
Stormwater Pollution Prevention plans (SPPP). These plans are required to include a comprehensive
evaluation of the site and operations to reduce pollutant sources and prevent pollutant discharge.
Copies of the general permits and accompanying documents can be accessed from the following webpage:
http://portal.nedenr.org/webfwq/ws/su/npdessw#General_Permits_NPDES. Permit text, technical bulletins,
discharge monitoring forms, and a Notice of Intent [which is the application for coverage under a NPDES
General Stormwater Permit] can be found on this website.
The following items are a subset of permit requirements and are listed to assist you and help bring your
attention to certain permitting issues, process and condition requirements of your. permit. Please see the
above mentioned website to obtain a copy of the permit so you may fully comply with all the conditions therein.
Failure to properly comply with conditions of the permit, like those bulleted below, is a violation(s) of
the permit and subject to civil penalty assessment(s) of up to $25,000.00 per day.
• Industrial facilities that fall into one of the subject ten categories are required to obtain permit coverage
under a general NPDES stormwater permit or an individual NPDES stormwater permit
• All persons desiring to have facilities covered by a General Permit must register with the Division of
Water Quality (DWQ) by filing of a Notice of Intent (NOI) and Applicable Fees.
• This Notice of Intent (NOI) must be submitted and a Certificate of Coverage issued prior to any
discharge of stormwater associated with the industrial activity, process wastewater, and/or mine
dewatering.
• Once the Notice of Intent is received, DWQ will review and determine whether a Certificate of Coverage
(COC) may be issued. If this Certificate of Coverage is issued the facility is covered by the General
Permit. That is, the permittee is authorized to discharge stormwater, process wastewater, and/or mine
dewatering pursuant to the type of General Permit until the permit expires or is modified or revoked.
• 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.
• There are currently 19 active general permits. Permit conditions vary accordingly-, however, most of the
permits have the following condition requirements (you must read your entire permit to ensure full
compliance):
o Development and compliance with the Stormwater Pollution Prevention Plan
o Collection, reporting, and recording of Analytical Monitoring

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C: A lower TSS benchmark of 50 mg/I for HQW, ORW, PNA and Tr Waters applies to these
.more sensitive waters.
• Sections B, C. The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
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 the Division's Stormwater Permitting Unit at [phone].

COC Number NCG030391
Mecklenburg County
Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 11 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state.ne.us/su/stormwater.htm]
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548

Inspection Summary. -
Facility Description:
Contech Construction Products specializes in bridge, drainage, earth stabilization, and stormwater solutions. The
Charlotte Plant manufactures corrugated metal pipe and fittings and distributes other highway construction products.
Corrugated metal pipe is made from coils of galvanized steel, aluminized steel, polymeric coated steel, and aluminum.
Fittings, bands, culvert end sections, and other products related to corrugated pipe are also manufactured and/or
stored on site. Other products not manufactured at this location but stored on site are geotextiles, geogrids, and plastic
pipe and fittings.
The facility is located on approximately 6.5 acres consisting of two manufacturing buildings and an office building. The
facility is comprised of approximately 99% impervious area that includes concrete and gravel. This facility does not
conduct vehicle washing on site nor does it conduct its own vehicle maintenance. An outside company is contracted to
come to the facility to conduct any required maintenance on the facility's small equipment. All used oil and filters are
taken off site.
Compliance History:
Ms. Erin Hall of Charlotte -Mecklenburg Storm Water Services CMSWS inspected the facility on May 7, 2008). The
Division of Water Quality issued a Notice of Deficiency on June 20, 2008.
Industrial Operations/City of Charlotte Stormwater Ordinance Review:
Arching Machine -
The initial inspection found that accumulated rainwater within the engine's secondary containment was at full capacity
and it was recommended that the accumulated rainwater be pumped out and properly disposed.
The follow-up inspection on August 6, 2008, found that accumulated rainwater had been pumped out and properly
disposed.
Reroll Machine — The initial inspection found that accumulated rainwater within the sump area beneath the machine is
pumped out and filtered via a 5-filter system setup that includes filters ranging from 5 — 15 microns and discharged to
the ground. It was recommended the facility cover the reroll machine area to avoid pumping and discharging
accumulated rainwater from the sump.
The follow-up inspection conducted on August 6, 2008 revealed that the reroll machine is now being covered with a
tarp to prevent rainwater accumulation. The tarp appeared to be in good condition.
Outdoor Paint Area — The initial inspection found that pipe painting was conducted intermittently on the concrete pad
adjacent to the reroll machine, which resulted in a significant amount of excess dried paint in this area. In addition, two
possible stormwater catch basins for Outfall 001 were observed within in the area that were not indicated on the
facility's SPPP site map. It was recommended that the permittee cease its current painting process and either conduct
painting inside away from stormwater exposure, cover the outside painting area, or place a tarp down to catch excess
paint and avoid stormwater contamination. The tarp would need to be taken inside when not in use and disposed of
properly when replaced.
The follow-up inspection conducted on August 6, 2008, revealed that the permittee is no longer painting within the
outside paint area. Painting now occurs inside the Fabricating Building and a tarp is available within this area if
painting needs to be conducted outdoors due to oversized product

it is water-cooled and a significant amount of oil -dry on the concrete area around the machine. It was recommended
that the permittee properly dispose of used oil -dry immediately after the spilled product been absorbed to prevent
stormwater contamination.
The follow-up inspection conducted on August 6, 2008 revealed that housekeeping around the yard saw had improved
and that no significant amounts of oil -dry were observed within the area.

Compliance History:
The permitteelfacility does not have any prior compliance issues with either the NC Division of Water Quality or
Charlotte -Mecklenburg Storm Water Services,
Industrial Operations/City of Charlotte,Stormwater Ordinance Review;
Aboveground Storage Tank (AST) —
One 9,000-gallon diesel fuel AST is located to the southeast of the property next to the fence. It is located in a covered
area and has secondary containment. It is not double -walled. The secondary containment is not equipped with a valve. If
a spill occurs, then FCC Environmental would respond and dispose of the spilled material. The AST is locked when not in
use. A spill kit is located in the immediate area.
Open -top Dumpsters —
Two open -top metal dumpsters were located to the southeast and northeast of the property. Both dumpsters contain
scrap metal and are picked up from an outside company on an as needed basis. The dumpsters are covered with tarps
when not in use and they appeared to be in good condition.
Hopper —
A small hopper was observed to the north of the property. It contained small pieces of scrap metal. Per facility personnel,
the hopper is taken inside the fabricating building at the end of the day. Scrap material is picked up by an outside
company on an as needed basis.
Fabricating Building —
The Fabricating Building is located to the southeast of the property. No floor drains are inside the building. No significant
amounts of chemicals are stored in this area.
Outdoor Storage Area —
Approximately five 55-gallon drums are stored on pallets on a concrete pad. They are located in a covered area adjacent
to the Fabricating Building. Drums contain metal parts that are used for construction jobs off site. No chemicals are stored
in this area. Final products are stored outside throughout the facility grounds.
Arching Machine —
This machine arches pipe into pipe -arch shapes. It is located outside on a concrete pad adjacent to the Fabricating
Page- 2

Permit: NCG030391 owner - Facility: Ccntech Construct Prod
Inspection Date: 05/07/2008 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Building. A sump area is located beneath the machine. No drains or valves are connected to the sump area, The engine
of the machine has a small secondary containment. Accumulated rainwater from this containment area as well as the
sump area is pumped out and disposed of by FCC Environmental. It was observed at the time of inspection that
accumulated rainwater within the engine's secondary containment was at full capacity.
The permittee should have accumulated rainwater pumped out and properly dispose of it.
Main Building —
The Main Building is located to the south of the property. A spill kit and supplies were observed at the entrance of the
building. Floor drains inside the building are not connected to any type of sewer system. They currently act as a sump
area if a spill would occur. Some drains have been filled in. Per facility personnel, future plans are to fill in and cap off all
floor drains. A parts washer is located inside the Main Building. US Filter is responsible for manifesting wastewater.
Material Storage —
Chemicals are stored inside the Main Building. A 250-gallon hydraulic AST, a 250-gallon new motor oil AST, a 200-gallon
waste oil AST, and approximately three 55-gallon drums of mineral spirits are stored within a concrete secondary
containment structure. This structure does not have a valve. If a spill occurs, then FCC Environmental would respond and
dispose of the spilled material. Two 25=gallon and two 55-gallon drums of mineral spirits and lubricant products are stored
in this area on portable spill containers. In another area within the Main Building, approximately five 5-gallon buckets of oil
were stored on a portable spill container,
Reroll Machine —
This machine recorrugates the ends of the pipe to allow the connection of the pipe with bands. It is located outside on a
concrete pad adjacent to the Main Building. A sump area is located beneath the machine. No drains or valves are
connected to the sump area. Per facility personnel, accumulated rainwater is pumped out and filtered via a 5-filter system
setup that includes filters ranging from 5 — 15 microns. Filtered rainwater is then discharged to the ground.
It is recommended the facility cover the Reroll machine area to avoid pumping and discharging accumulated rainwater
from the sump.
Outdoor Paint Area —
An outside area on the concrete pad adjacent to the Reroll machine is used by facility personnel to paint the ends of pipes
using a galvanized paint. Paint is applied using a sprayer and is conducted approximately every other month.
Approximately five gallons of paint is used over a week when painting occurs. A significant amount of excess dried paint
was observed in this area. Two possible stormwater catch basins were observed within this area. These were not
indicated on the facility's site map. It did appear that they may tie into stormwater piping that would discharge from Outfall
001.
The permittee should cease its painting process in the way it is currently being conducted. Recommendations include
painting inside away from stormwater exposure, covering the outside area, or putting a tarp down to catch excess paint.
The tarp would need to be taken inside when not in use and disposed of properly when replaced.
Yard Saw —
The yard saw is located to the south of the property next to the fence. A moderate amount of water was observed on the
ground around the machine_ Per facility personnel, the machine is water cooled thus the reason for the excess water
within this area. The water is potable water. A significant amount of oil -dry was observed on the concrete area around the
machine.
The facility should properly dispose of used oil -dry immediately after the spilled product has soaked in completely

and longitude coordinates for the points of discharge and does not identify whether the
receiving stream is impaired or located in a watershed for which a TMDL has been
established as required by the general permit issued in November of 2007. The SPPP
contains a detailed site map, but does not include the percentage of each drainage area
that is impervious or a narrative description of the potential pollutants that might be
present in the stormwater discharge from each autfall.
The permittee could not provide documentation that employee training was conducted
for 2003 and 2005 or that the SPPP had been reviewed and updated on an annual
basis. The permittee conducted a Stormwater Facility Inspection on 4/21108, but no other
documentation could be provided for previous inspections. The permittee has not fully
implemented the SPPP due to the lack of monitoring, training, and inspections for the
past five years.

# Is a copy of the Permit and the Certificate of Coverage available at the site?
# Were all outfalls observed during the inspection?
# If the facility has representative outfall status, is it properly documented by the Division?
# Has the facility evaluated all illicit (non stormwater) discharges?
Comment: Stormwater from the southwest portion of the site flows to either a catch
basin that discharges from Outfall 001 or as sheet flow to a stormwater conveyance
ditch_ Stormwater from the southeast flows to either a catch basin that discharges to
Outfall 002 or as sheet flow to a stormwater conveyance ditch. The stormwater
conveyance ditch is located to the south of the property on the other side of the facility's
fence next to a railroad track. Outfalls 001 and 002 discharge to this stormwater
conveyance ditch as well. Stormwater from the north side of the property flows as sheet
flow to Raleigh Street into the City of Charlotte's municipal separate storm sewer
system. All stormwater discharges from the property flow to an unnamed tributary to
Little Sugar Creek.

They will be properly disposed when replaced. We have included the named catch basins on our site
map.
Issue — Yard Saw — Properly dispose of oil dry immediately after use.
Response — Area is cleaned and swept after use daily. Oil dry is properly disposed.

Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the I 1 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state.ne.us/su/stormwater.htmi
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548
