Subject: NPDES Stormwater Permit Coverage Renewal
Air Systems Components
COC Number NCG030469
Edgecombe County
In response to your renewal application for continued coverage under stormwater General Permit NCG030000
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 (COC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (http:// op_rtal.ncdenr.org/web/wg/ws/sulcurrent-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
h_ttp://Portal.ncdenr.org/web/wq/ws/su/npdessw (click on `General Permits' tab) to review that information
for your specific General Permit carefully.

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 HOW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections 6, 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].
Sincerely,
for Charles Wakild, P.E.

VIA CERTIFIED MAIL, RETURN RECEIPT REQUESTED
Myrl Nisely
Acting Raleigh Regional Surface Water Quality Supervisor
North Carolina Division of Water Quality
1628 Mail Service Center
Raleigh, NC 27699-1628
RE: Notice of Violation, NOV-2006-PC-0258,
NPDES General Stormwater Permit NCG030469
Dear Mr. Nisely,
This letter is Air System Components LP's (ASC) response to the Notice of Violation
(NOV) dated June 21, 2006 and issued to ASC. While the NOV contains numerous
findings, ASC disputes the allegation that each finding constitutes a violation. The NOV
requested that ASC respond to the allegations contained in paragraphs 2-4 of the NOV.
During the June 15 stormwater inspection, there were no visible evidence of spills,
overflows or similar incidents in the system. The discharge was clear and free of
excessive solids or foam. The facility had conducted the qualitative inspections as
required in the.permit..Analytical testing had, a]so been conducted annually, even though
the permit only requires this during.the first year of thc-permit term: Both -the qualitative
inspections and analytical testing showed no signs of storm water pollution. Below are
the allegations contained in paragraphs 2-4 of the NOV and ASC's responses to those
paragraphs.
NOV Paragraph 2: There were a few items stored in the covered yard on the east side
of the facility. that caused some concern. There were 5-gallon buckets labeled as
coolants and lubricants, some of which were full, while others were partially full or
completely empty. Additionally, there were 5-gallon buckets of paint stored there.
Response: The items observed during the inspection have been placed on spill
containment pallets. The buckets of paint have been placed inside the plant in the paint
storage room. All items contain proper labels.
NOV Paragraph 3: There is a storage area on the far north side of the northern parking
lot where you are currently. storing a variety of items including storage shelving, plant
equipment, recyclable cardboard and 55-gallon drums.. Five of,the55-gallon' drums had"
something in them at the time of the inspection and were not appropriately labeled.
Unless these drums are still properly sealed as they were when originally received from
the manufacturer, they should -be placed under cover to protect them from precipitation.

4" }

Additionally, please ensure that these drums are properly labeled and that waste products
are properly disposed of in a timely manner to ensure that this storage area doesn't evolve
into a hazardous waste storage area.
Response: The drums in the finding have been labeled properly and subsequently
disposed of. Any drums of used oil that the plant produces will be stored on secondary
containment pallets under the covered are until disposal.
NOV Paragraph 4.a: The general location map (GLM) should show the conveyance by
which stormwater leaving your site reaches the Tar River. Also, please label the Tar
River on the GLM and show an accurate latitude and longitude for the SDO.
Response: The Area Map has been updated in Appendix A of the SWPPP. The
Tar River is labeled and the latitude and longitude is listed for the SDO.
NOV Paragraph 4.b.: Your site map must be drawn to scale. It should reflect the
separate drainage areas and indicate the direction of flow for each drainage area. The
drainage areas served by each outfall should be delineated on the plan and the plan
should specify the percentage of your site that is impervious surface.
Response: The site map is currently drawn to scale in Appendix B of the
SWPPP. The drainage ditches on the property have been added to the map along with
their flow direction. The percentage of paved surface has been added
NOV Paragraph 4.c.: There was no list of significant spills that have occurred at your
site over the past three years, in spite of the fact that you did have one small hydraulic
fluid spill last fall. Please ensure that all spills are recorded and reported as required.
Also, during those years that you have no spills, you may enter a short memo into the
SP3, perhaps as part of your annual review, that is signed and dated and states that no
spills have occurred over the past 12 months.
Response: The facility has not had a significant spill in the last 3 years.
Nonetheless, information regarding the small spill last fall has been entered into section 7
of the SWPPP. Information regarding any additional spills will be added as part of
annual review of the plan.
NOV Paragraph 4.d.: There was no list of potential pollutants. Please compile a list of
potential stormwater pollutants for the SP3. Alternatively, is such a list can be found in
another on -site program, please reference its location in the SP3 to facilitate a simpler
inspection process.
Response: Appendix C of the SWPPP currently lists potential stormwater
pollutants. The best management practices for these possible pollutants are contained in
Appendix D of the SWPPP. The Material Safety Data Sheets (MSDS) are also a source
for potential stormwater pollutants, and have now been referenced in section 6.0 of the
SWPPP.

NOV Paragraph 4.e.: There was no certification that your SDO has been evaluated for
the presence of non-stormwater discharges. Please make this evaluation and have it
signed by the appropriate individual. Ensure certification/signature are completed in
accordance with the signatory requirements found in Part III, Section B, Paragraph 5, of
your permit. Be sure to file the completed certification in the SP3 folder.
Response: The facility conducted the required qualitative inspections as required
on June 26, 2006.
NOV Paragraph 4.£: Your Spill Prevention and Response Plan (SPRP) is not fully
developed. You have not identified a spill response/cleanup team. Please ensure you
fully develop the SPRP and identify those individuals responsible for implementing the
plan. Also, please ensure the SPRP is site stormwater specific.
Response: A list of spill response team members has been added to section 9.1 of

Subject: Notice of Violation, NOV-2006-PG-0258, Resulting from
Stormwater Compliance Evaluation Inspection
Air System Components, Inc.
NPDES General Stormwater Permit NCG030469
Edgecombe County
Dear Mr. Hardison:
On 15 June 2006, Ronald Boone of the Divison of Water Quality's (DWQ) Raleigh Regional Office conducted a
stormwater Compliance Evaluation Inspection (CEI) of the subject facility. Your assistance and cooperation were
helpful and appreciated. Inspection checklists are attached for your review. Inspection findings are listed below.
INDUSTRY AND SITE DESCRIPTION
Air System Components, Inc. (ASC) manufactures components for air handling systems at this facility, placing it under
standard industrial classification code (SIC) 34, fabricating of metal products. Stormwater run-off generated at such
facilities is regulated by general NPDES stormwater permit NCG030000. DWQ has therefore issued ASC certificate of
coverage (COC) NCG030469, which became effective on 1 September 2002 and expires on 31 August 2007.
Stormwater generated at the site is collected via a system of in -ground drains and stormwater ditches that surround most
of the property. The drains and ditches convey stormwater to one stormwater discharge outfall (SDO) located at the
northeast corner of the property. Stormwater is discharged into the Tar River, a Class WS-IV, nutrient sensitive water
(NSW), in the Tar -Pamlico River Basin.
INSPECTION SUMMARY
SITE/FACILITY
1. The SDO was identified and inspected. There was no visible evidence of spills, overflows or similar incidents in
the system. No significant erosion was found. The discharge was clear and free of excessive solids and/or foam.
2. There were a few items stored in the covered yard on the east side of the facility that caused some concern. There
were 5-gallon buckets labeled as coolants and lubricants, some of which were full, while others were partially full
or completely empty. Additionally, there were 5-gallon buckets of paint stored there.
The majority of the materials are well organized and the cover would protect the items from all but the most violent
of storms. However, a spill on this pad could wash out from under the cover and end up in the stormwater drainage
system before it was contained and/or cleaned up, You should consider placing a concrete containment berm
around this storage pad that would contain any items that are accidentally spilled until cleanup crews were able to
recover the material.

Also, please ensure that these drums and buckets are properly labeled and that waste products are properly disposed
of in a timely manner to ensure that your storage pad doesn't evolve into a hazardous waste storage area.
3. There is a storage area on the far north side of the northern parking lot where you are currently storing a variety of
items including storage shelving, plant equipment, recyclable cardboard and 55-gallon drums. Five of the 55-gallon
drums had something.in them at the time of the inspection and were not appropriately labeled. Unless these drums
are still properly sealed as they were when originally received from the manufacturer, they should be placed under
cover to protect them from precipitation. Additionally, please ensure that these drums are properly labeled and that
waste products are properly disposed of in a timely mariner to ensure that this storage area doesn't evolve into a
hazardous waste storage area.
STORMWATER PROGRAM
4. Your stormwater pollution prevention plan (SP3) was reviewed and the following items were noted:
a. The general location map (GLM) should show the conveyance by which stormwater leaving your site reaches
the Tar River. Also, please label the Tar River on the GLM and show an accurate latitude and longitude for the
SDO.
b. Your site map must be drawn to scale. It should reflect the separate drainage areas and indicate the direction of
flow for each drainage area. The drainage areas served by each outfall should be delineated on the plan and the
plan should specify the percentage of your site that is impervious surface.
c. There was no list of significant spills that have occurred at your site over the past three years, in spite of the fact
that you did have one small hydraulic fluid spill last fall. Please ensure that all spills are recorded and reported
as required. Also, during those years that you have no spills, you may enter a short memo into the SP3, perhaps
as part of your annual SP3 review, that is signed and dated and states that no spills have occurred over the past
12 months.
d. There was no list of potential pollutants. Please compile a list of potential stormwater pollutants for the SP3.
Alternatively, if such a list can be found in another on -site program, please reference its location in the SP3 to
facilitate a simpler inspection process,
e. There was no certification that your SDO has been evaluated for the presence of non-stormwater discharges.
Please make this evaluation and have it signed by the appropriate individual, Ensure certification/signature are
completed in accordance with the signatory requirements found in Part III, Section B, Paragraph 5, of your
permit. Be sure to file the completed certification in the SP3 folder.
Your Spill Prevention and Response Plan (SPRP) is not fully developed. You have not identified a spill
response/cleanup team. Please ensure you fully develop the SPRP and identify those individuals responsible
for implementing the plan. Also, please ensure the SPRP is site stormwater specific.
g. You currently do not have a preventative maintenance and good housekeeping program. This program should
document schedules of inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspections and regular cleaning of material handling areas should be incorporated into this
Program.
h. Your employee -training program is not fully developed/implemented. Please develop a training program for all
personnel who, in the course of their duties, have the potential to contaminate stormwater run-off. The program
should include schedules and annual training on proper spill response and cleanup and preventative
maintenance activities. Also, those personnel responsible for developing and implementing the training
program must be identified.

i. The person/personnel responsible for the overall coordination, development, implementation and revision of the
SP3 have not been identified. Please develop a list of those responsible for each component of the SP3 and
keep it up to date and in the SP3 at all times.
The SP3 has not been reviewed and updated on an annual basis. Please ensure the SP3 is reviewed on an
annual basis and that it is updated appropriately.
k. The SP3 currently does not include a stormwater facility inspection program. Please develop such a program
and conduct the inspections semi-annually, once in the fall (Sep -Nov) and once in the spring (Apr -Jun).
Inspections and resulting maintenance activities must be documented in the SP3, along with the dates and times
of inspection, the name of the individuals making the inspections, and a narrative description of the planfs
stormwater control systems, plant equipment and systems. Analytical and qualitative monitoring of the
stormwater discharges must be accomplished in addition to these inspections, but can be accomplished
concurrently.
It is possible, with some modifications to your site, that you could self -certify for a no -exposure certificate. Please
review attachments 2 and 3 and consider whether you may wish to attempt self -certification. A no exposure certificate
would remove the burden of your stormwater discharge permit but would still leave you open to inspection by DWQ
and responsible for the proper management of your stormwater discharges.
Please be aware that the above -mentioned issues constitute violations of your stormwater discharge permit and that such
violations may result in the assessment of civil penalties in an amount of up to $25,000 per day per violation. Please
provide a response to the violations identified in paragraphs 2-4 above within 30 days of your receipt of this letter. Your
response should include a narrative as well as a tentative schedule for you to correct the identified violations. If you or
your staff has any questions regarding the inspection or this letter, please feel free to call Ron Boone for assistance at
919-7914200.

Storm Water Phase 11
Final Rule
Conditional No Exposure
Exclusion for Industrial Activi
Why Is the Phase I No Exposure Exclusion Addressed in the Phase 11 Final
Rule?
The 1990 storm water regulations for Phase I of the federal storm water program identify
eleven categories of industrial activities that must obtain a National Pollutant Discharge
Elimination System (NPDES ) permit. Operators of certain facilities within category eleven
(xi), commonly referred to as "light industry," were exempted from the definition of "storm
water discharge associated with industrial activity," and the subsequent requirement to obtain
an NPDES permit, provided their industrial materials or activities were not "exposed" to storm
water. This Phase I exemption from permitting was limited to those facilities identified in
category (xi), and did not require category (xi) facility operators to submit any information
supporting their no exposure claim.
In 1992, the Ninth Circuit court remanded to EPA for further rulemaking the no exposure
exemption for light industry after making a determination that the exemption was arbitrary
and capricious for two reasons. First, the court found that EPA had not established a record
to support its assumption that light industrial activity that is not exposed to storm water (as
opposed to all other regulated industrial activity not exposed) is not a "storm water discharge
associated with industrial activity." Second, the court concluded that the exemption
impermissibly relied on the unsubstantiated judgment of the light industrial facility operator to
determine the applicability of the exemption. This fact sheet describes the revised conditional
no exposure exclusion as presented in the Phase H Final Rule.
Who is Eligible to Claim No Exposure?
As revised in the Phase II Final Rule, the conditional no exposure exclusion applies to ALL
industrial categories listed in the 1990 storm water regulations, except for construction
activities disturbing 5 or more acres (category (x)).
What Is The Regulatory Definition of "No Exposure"?
he intent of the no exposure provision is to provide facilities with industrial materials and
activities that are entirely sheltered from storm water"a simplified way of complying with the
storm water permitting provisions of the Clean Water Act (CWA). This includes facilities that
are located within a larger office building, or facilities at which the only items permanently
exposed to precipitation are roofs, parking lots, vegetated areas, and other non -industrial areas
or activities. The Phase 11 regulatory definition of "no exposure" follows.
No exposure means all industrial materials and activities are protected by a
storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or
runoff. Industrial materials or activities include, but are not limited to, material
handling equipment or activities, industrial machinery, raw materials,
intermediate products, by-products, final products, or waste products.

Fact Sheet 4.4 — Conditional No Exposure Exclusion for Industrial Activity Page 2
A storm resistant shelter is not required for the following
industrial materials and activities:
❑ Drums, barrels, tanks, and similar containers that are
tightly sealed, provided those containers are not
deteriorated and do not leak. "Sealed" means banded
or otherwise secured and without operational taps or
valves;
C] Adequately maintained vehicles used in materials
handling; and
❑ Finai products, other than products that would be
mobilized in storm water discharges (e.g., rock salt).
The term "stone -resistant shelter," as used in the no exposure
definition, includes completely roofed and walled buildings
or structures, as well as structures with only a top cover but
no side coverings, provided material under the structure is not
otherwise subject to any run-on and subsequent runoff of
stone water, While the intent of the no exposure provision is
to promote a condition of permanent no exposure, EPA
understands certain vehicles could became temporarily
exposed to rain and snow while passing between buildings.
Adequately maintained mobile equipment (e.g., trucks,
automobiles, forklifts, trailers, or other such general purpose
vehicles found at the industrial site that are not industrial
machinery, and that are not leaking contaminants or are not
otherwise a source of industrial pollutants) can be exposed to
precipitation or runoff. Such activities alone would not
prevent a facility from certifying to no exposure. Similarly,
trucks or other vehicles awaiting maintenance at vehicle
maintenance facilities that are not leaking contaminants or are
not otherwise a source of industrial pollutants, are not
considered "exposed."
In addition, EPA recognizes that there are circumstances
where permianent no exposure of industrial activities or
materials is not possible and, therefore, under such
conditions, materials and activities can be sheltered with
temporary covers (e.g., tarps) between periods of permanent
enclosure. The no exposure provision does not specify every
such situation, but NPDES permitting authorities can address
this issue on a case -by -case basis.
The Phase II Final Rule also addresses particulate matter
emissions from roof stacks/vents that are regulated by, and in
compliance with, other environmental protection programs
(i.e., air quality control programs) and that do not cause storm
water contamination are considered not exposed. Particulate
matter or visible deposits of residuals from roof stacks and/or
vents not otherwise regulated (i.e., under an air quality
control program) and evident in storm water outflow are
considered exposed. Likewise, visible "track out" (i.e.,
pollutants carried on the tires of vehicles) or windblown raw
materials is considered exposed. Leaking pipes containing
contaminants exposed to storm water are deemed exposed,
as are past sources of storm water contamination that remain
onsite. General refuse and trash, not of an industrial nature,
is not considered exposed as long as the container is
completely covered and nothing can drain out holes in the
bottom, or is lost in loading onto a garbage truck. Industrial
refuse and trash that is left uncovered, however, is considered
exposed.
What is Required Under the No Exposure
Provision?
The Phase II Final Rule represents a significant expansion
in the scope of the original no exposure provision in
terms of eligibility (as noted above) and responsibilities
for facilities claiming the exclusion. Under the original no
exposure provision, a light industry operator was expected
to make an independent determination of whether there was
"exposure" of industrial materials and activities to storm
water and, if not, simply not submit a permit application.
An operator seeking to qualify for the revised conditional
no exposure exclusion, including light industry operators
(i.e., category (xi) facilities), must:
Q Submit written certification that the facility meets the
definition of "no exposure" to the NPDES permitting
authority once every 5 years.
The Phase 11 Final Rule includes a four -page
No Frposure Certification form that uses a series
of yes/no questions to aid facility operators in
determining whether they have a condition of
no exposure. It also serves as the necessary
certification of no exposure provided the operator
is able to answer all the questions in the negative,
EPA's Certification is for use 2"l by operators of
industrial activity located in areas where EPA is the
NPDES permitting authority.
• A copy of the Certification can be obtained from
the U.S. EPA Office of Wastewater Management
(OWM) web site, the Storm Water Phase II Final
Rule published in the Federal Register (Appendix
4), or by contacting OWM.
Submit a copy, upon request, of the Certification to the
municipality in which the facility is located.
a Allow the NPDES permitting authority or, if
discharging into a municipal separate storm sewer
system, the operator of the system, to; (1) inspect the
facility; and (2) make such inspection reports publicly
available upon request.
Regulated industrial operators need to either apply for a
permit or submit a no exposure certification form in order to
be in compliance with the NPDES storm water regulations.
Any permit held becomes null and void once a certification
form is submitted.

Fact Sheet 4.0 — Conditional No Exposure Exclusion for Industrial Activity Page 3
Even when an industrial operator certifies to no exposure,
the NPDES permitting authority still retains the authority to
require the operator to apply for an individual or general
permit if the NPDES permitting authority has determined that
the discharge is contributing to the violation of, or interfering
with the attainment or maintenance of, water quality
standards, including designated uses.
Are There Any Concerns Related to Water
Quality Standards?
Yes. An operator certifying that its facility qualifies for
the conditional no exposure exclusion may, nonetheless,
be required by the NPDES permitting authority to obtain
permit authorization. Such a requirement would follow
the permitting authority's determination that the discharge
causes, has a reasonable potential to cause, or contributes to
a violation of an applicable water quality standard, including
designated uses. Designated uses can include use as a
drinking water supply or for recreational purposes.
Many efforts to achieve no exposure can employ simple
good housekeeping and contaminant cleanup activities such
as moving materials and activities indoors into existing
buildings or structures. In limited cases, however, industrial
operators may make major changes at a site to achieve no
exposure. These efforts may include constructing a new
building or cover to eliminate exposure or constructing. .
structures to prevent run-on and storm water contact with
industrial materials and activities. Major changes undertaken
to achieve no exposure, however, can increase the impervious
area of the site, such as when a building with a smooth roof is
placed in a formerly vegetated area. Increased impervious
area can lead to an increase in the volume and velocity of
storm water runoff, which, in turn, can result in a higher
concentration of pollutants in the discharge, since fewer
pollutants are naturally filtered out.
The concern of increased impervious area is addressed in one
of the questions on the Certification form, which asks, "Have
you paved or roofed over a formerly exposed, pervious area
in order to qualify for the no exposure exclusion? If yes,
please indicate approximately how much area was paved or
roofed over." This question has no affect on an operator's
eligibility for the exclusion. It is intended only to aid the
NPDES permitting authority in assessing the likelihood
of such actions interfering with water quality standards.
Where this is a concern, the facility operator and its NPDES
permitting authority should take appropriate actions to ensure
that water quality standards can be achieved.
What Happens if the Condition of No Exposure
Is Not Maintained?
Under the Phase II Final Rule, the no exposure exclusion
is conditional and not an outright exemption. Therefore,
if there is a change in circumstances that causes exposure of
industrial activities or materials to storm water, the operator is
required to comply immediately with all the requirements of
the NPDES Storm Water Program, including applying for and
obtaining a permit.
Failure to maintain the condition of no exposure or obtain
coverage under an NPDES storm water permit can lead to
the unauthorized discharge of pollutants to waters of the
United States, resulting in penalties under the CWA. Where
a facility operator determines that exposure is Iikely to occur
in the future due to some anticipated change at the facility,
the operator should submit an application and acquire storm
water permit coverage prior to the exposed discharge to avoid
such penalties.

North Carolina No Exposure Certification Guidance
Black -NC no exposure form
Red -From EPA guidance
Blue -Recommended additions to Guidance Document
Submission of the NC No Exposure Certification form constitutes notice that the entity identified in the
Form does not require permit coverage from the state of North Carolina for its stormwater discharge
associated with one of the industrial activities identified in 40 CFR 122.26(b)(14) due to the existence of a
condition of no exposure.
A condition of no exposure exists at an industrial facility when all"indTti-iahmaterials and activities are
protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or runoff,
Industrial materials or activities include, but are not limited to, ritaterial handling equipment or activities,
industrial machinery, raw materials, intermediate products, by-pioducts,.final products, or waste products.

Material handling activities include storage, loading and unloading, transportation, or conveyance of any
raw materials, intermediate products, final product, or waste productfWhile the intent of the no exposure
exclusion is to promote a condition of permanent no exposure, a storm -resistant shelter is not required for
the following industrial materials and activities provided the facility has not had any releases in the past 3
years, the facility has developed an implemented A"SPCC"pia an inspection and maintenance program,
and site specific material handling procedure5:r�
Final products, other than products that'w ld mobilize in stormwater discharges (e.g., rock

otherwise secure and without operational taps or valves), provided those containers are not
deteriorated or damaged, and do not leak. Containers, such as drums, barrels, pails, and totes
must also meet all DDT specifications, including compatibility.
Any addition to or withdrawal from the containers while outdoors will not allow the facility to certify no
exposure.
For ASTs to be operational and qualify for no exposure:
• ASTs must be physically separated from and not associated with vehicle maintenance.
• There must be no piping, flanges, valves, pumps or other equipment leaking contaminants that
could contact stormwater.
• The tanks and piping must be protected from traffic lanes to minimize exposure.
• Wherever feasible, AST should be surrounded by some type of physical containment.
• ASTs are exempt form the prohibition against adding to or withdrawing material from containers,
provided the facility has not.had any releases in the past 3 years, the facility has developed an
implemented an SPCC plan, an inspection and maintenance program, and site specific loading
and unloading procedures.
A no Exposure Certification must be provided for each facility qualifying for the no exposure exclusion.
In :addition, the exclusion from NPDES permitting is available on a facility -wide basis only, not for
individual outfalss. If any industrial activity or materials are or will be exposed to stormwater runoff, the
facility is not eligible for the no -exposure.

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 NPDFS permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,0W per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 1 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.nc.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.
