Long Agribusiness LLC
111 Fairview Street,
Tarboro, NC 27886
Subject: Notice of Violation (NOV-2006-PC-0077)
Resulting from Compliance Evaluation Inspection
on 9 March 2006, on NPDES General Stormwater
Certificate of Coverage (COC) NCG030292
Long Agribusiness LLC, Tarboro
Edgecombe County
Dear Mr. Elliott,
Mr. Ronald Boone, of the North Carolina Division of Water Quality, Surface Water Protection Section,
conducted a compliance evaluation inspection (CEI) for the permit referenced above at Long
Agribusiness LLC's Tarboro, NC plant on 9 March 2006. Thank you for your assistance and
cooperation in providing him a tour of the site, as well as an interview to review your stormwater
management program.
Your permit/COC was issued on 31 August 2002 by authority of North Carolina General Statute
(NCGS) 143-215.1. This permit is intended to help prevent pollution of state waters that receive
stormwater discharges from your facility. Compliance with this permit, as observed during Mr. Boone's
inspection at your plant, is discussed below. Please use the permit references listed throughout this
report for further explanation of each item cited.
SITE SUMMARY
• This plant is a metal products fabricating facility dealing primarily with the assembly of farm
equipment and the fabrication of attachments for such equipment.
• Stormwater generated at your site is collected via a system of in -ground drains. All stormwater is
discharged via one of ten outfalls identified in your current Stormwater Pollution Prevention Plan
(SP3).
• Stormwater is discharged from your plant to either an unnamed tributary to Hendrick's Creek, a class
C nutrient sensitive water (NSW), or to Tarboro's municipal separate storm sewer system (MS4),
which ultimately discharges through the east Tarboro canal into the Tar River, also a class C NSW.
Both receiving streams are located in the Tar -Pamlico river basin.

INSPECTION FINDINGS
• In general the site was clean and well maintained.
• The number of outfalls identified on the general location map in your SP3 is inaccurate. The outfalls
shown were correct as of the date of your SP3 (2002), but you have since made changes to the
outfalls. Please change your SP3 and all related materials to reflect the correct number of outfalls,
with each outfall's exact location, latitude/longitude, and receiving stream. Also, ensure that you
show the conveyance between the outfall and the receiving stream, if applicable. Faifure to do so
places you in violation of Part 11, Section A, Paragraph la.
• The site map does not delineate drainage areas for each outfall and does not include a list, or a
reference to a list, of potential stormwater pollutants on site. Also, please ensure the map is drawn to
scale and that you keep it updated. It is currently out-of-date because you still show parcel 3 to be a
part of your property, but you actually sold parcel 3 to another party some time ago (Part IT, Section
A, Paragraph lc).
• The list of significant spills you have had at your site in the previous three years is outdated (Part II,
Section A, Paragraph ld).
• Stormwater discharges have not been certified for the presence of non-stormwater discharges as
required in Part II, Section A, Paragraph 1e.
• You stated that the personnel responsible for your Spill Prevention and Response Plan (SPRP - Part
II, Section A, Paragraph 3) are also responsible for your Contingency Plan and Spill Prevention,
Control and Countermeasure (SPCC) plan required by the EPA. This is acceptable only if you
ensure these programs meet the site -specific nature of your SPRP and that all SPRP required
components that are kept in the other plans are properly referenced so personnel using your SPRP
know where to go to find those required components. Please ensure each plan is updated
accordingly, so in the end it provides you with the most effective means of responding to and
cleaning up spills.
• Your SP3 had a Preventative Maintenance and Good Housekeeping Plan but neither program had
been implemented. Schedules of the required maintenance and housekeeping and forms showing
that the maintenance and housekeeping had been accomplished were not available. Please ensure
you update your SPYs maintenance and housekeeping programs and then implement the programs
fully (Part U, Section A, Paragraph 4).
• Your employee -training program had not been properly implemented. There were no training
records or schedules available for inspection. Please implement this important program immediately
according to the guidelines found in Part IT, Section A, Paragraph 5.
• The person(s) responsible for the overall coordination, development, implementation, and revision of
the SP3 were not identified in the SP3 as required in Part II, Section A, Paragraph 6.
• Your SP3 has not been reviewed and updated on an annual basis as required in Part 11, Section A,
Paragraph 7.
• Semi-annual inspections of your facility, as required in Part 11, Section A, Paragraph 8, are not being
accomplished.
• Your SP3 has not been fully implemented as required in Part II, Section A, Paragraph 9.
• Neither analytical monitoring nor qualitative monitoring results were available for inspection,
suggesting that the required monitoring is not being accomplished as required in Part II, Section A
and Section B.
The above -mentioned conditions and/or practices demonstrate mismanagement of your stormwater
program and/or a misunderstanding of the requirements of your permit. Please be aware that violations

•Lpng Agribusiness LLC, Compliance Evaluation inspection, 9 March 2006, NCG030292 Page 3 of 3
of the conditions of your permit could result in the assessment of civil penalties in an amount of up to
$25,000 per day per violation.
Please reply within 30 days of your receipt of this letter with a narrative of your plan to achieve full
compliance with your permit and your schedule for doing so. If you need assistance with understanding
any aspect of your permit, please do not hesitate to contact Mr. Boone for assistance at 919-791-4259.

Subject: NPDES Stormwater Permit Renewal
LONG AGRIBUSINESS LLC
COC Number NCG030292
Edgecombe 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 I I 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.html
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 Joe Albiston of the Raleigh
Regional Office at 919-571-4700 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548

PERMIT TO DISCHARGE STORMWATER
Permit No. NCG030000 Date: April 28, 1997
l . TYPES OF DISCHARGES COVERED
a. Industrial Activities Covered by this General Permit
Coverage under this general permit is applicable to all owners or operators of stormwater point
source discharges associated with activities classified as establishments primarily engaged in
the rolling, drawing, and extruding of nonferrous metals [standard industrial classification
(SIC) 335], fabricating of metal products (SIC 34), manufacturing of industrial and
commercial machinery (SIC 35), manufacturing of electronic equipment (SIC 36),
manufacturing of transportation equipment (SIC 37), and the manufacturing of measuring and
analyzing instruments (SIC 38).
This permit does not cover the building and repairing of ships (SIC 373), which is covered by
the general stormwater permit NCG 190000 instead.
Facilities with the SIC codes of 34 (except 3441), 35, 36, 37, and 38 are exempted from the
requirements to obtain a stormwater permit if they do not have areas where material handling
equipment or activities, raw material, intermediate products, final products, waste materials,
by-products, or industrial machinery exposed to stormwater. Exposure includes the following
activities;
i) Dumpsters containing trash associated with the manufacturing process that are exposed to
rainfall and subsequent runoff. Compaction dumpsters that are loaded from inside a
building with the dumpster itself fully enclosed are not considered exposure.
ii) Wood pallets that have been used to store or transfer materials associated with the
industrial manufacturing operations which are stored outside are considered materials
exposed. The same interpretation applies to any type of racking system that is used to store
materials associated with the industrial activity.
iii) Bulk storage of liquid products that has no secondary containment or that has secondary
containment with a direct, uncontrolled connection to the stormwater conveyance system.
iv) Drums, full or empty, that are stored outside, such that stormwater can wash through
the storage area without control and discharge to the stormwater conveyance system.
b. Types of Operations Covered
This permit covers any stormwater discharges that leave any of the industrial activities
described above. The practice of most concern at these types of activities is the storage of raw
and waste materials outside where they may come into contact with stormwater runoff, thereby
contaminating it. Another concern is any storage tanks or drums of solvents or paints used to
treat various metal products that could spill into the stormwater system if they were to leak.
Page I of 10

c. Characteristics of Discharged Stormwater
Data submitted to the U.S. Environmental Protection Agency (EPA) during the group
stormwater permit application process included quantitative analyses of grab samples for
various pollutants in stormwater runoff from metal fabrication facilities throughout the country
was examined. Data received from the analytical monitoring conducted for the existing
NCG030000 general stormwater permit was also reviewed. Analyses of these data indicated
that pollutant parameters of particular concern in this industry are Lead, pH, Total Suspended
Solids, and various toxic organics that are used at some facilities. A narrative explanation of
the data analysis is provided in the Appendix.
d. Geographic Area(s) Covered by this General Permit
Discharges covered by this General Permit are located at any place within the political boundary
of the State of North Carolina. Discharges located on the Cherokee Indian Tribal Reservation
are subject to permitting by the US Environmental Protection Agency and are not covered by
this General Permit.
e. Receiving Waters
Receiving waters include all surface waters of North Carolina or municipal separate storm
sewer systems conveying stormwater to surface waters:

The draft permit provides for the use of cut-off concentrations in order to minimize the required
analytical monitoring for facilities which are not significant contributors to stormwater pollution.
These cut-off concentrations are not intended to be effluent limits, but provide guidelines for
determining which facilities may be major contributors to stormwater pollution and need further
monitoring. The arithmetic mean of all monitoring data collected during the term of the permit
must be calculated for each parameter and compared to the cut-off concentration. If the mean is
less than the permitted cut-off concentration, then the facility may discontinue analytical monitoring
for that parameter at that outfall until the final year of the permit. This approach prohibits facilities
from using the cut-off concentrations as target concentrations.
Stormwater must further be controlled by the development and implementation of a Stormwater
Pollution Prevention Plan (Plan). The following are specific requirements of the Plan:
1. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
Page 2 of 10

(c) 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.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 5.
2. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the
following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulls storage of liquid materials, storage of Section 313 of Title III 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 am connected directly to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices [which shall be secured with a locking
mechanism] and any stormwater that accumulates in the containment area shall be at
a minimum visually observed for color, foam, outfall staining, visible sheens and
dry weather flow, prior to release of the accumulated stormwater. Accumulated
stormwater shall be released if found to be uncontaminated by 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.
Page 3 of 10

(d) Inspection Schedule. Schedules for inspection of stormwater conveyances,
controls, and measures to be taken to limit or'prevent erosion associated with the
stormwater systems.
3. Spill Prevention and Response PIan. 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 tunes 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 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 at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all Versonnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. 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.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the 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 that the changes have
been made.
8. Facility Inspections Program. Facilities are required to inspect all 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 a narrative description of the facility's stormwater control systems, plant
equipment and systems. 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.
Page 4 of 10

9. Implementation. The permittee shall document all monitoring, measurements, inspections
and maintenance activities and training provided to employees, including the log of the
sampling data and -of activities taken to implement BMPs associated with the industrial
activities, including vehicle maintenance activities. Such documentation shall be kept on -
site for a period of five years and made available to the Director or his authorized
representative immediately upon request.
3. MONITORING AND REPORTING REQUIREMENTS
The draft permit specifies monitoring and reporting requirements for both quantitative and
qualitative assessment of the stormwater discharge and operational inspections of the entire facility.
Specific pollutant parameters for which sampling must be performed and the frequency of the
sampling are based upon the types of materials used and produced in the manufacturing processes
and the potential for contamination of the stormwater runoff at these facilities. The draft permit
proposes specific monitoring requirements for the following parameters: Lead, pH, Total
Suspended Solids, and various tonic organics that are used at some facilities, Total Rainfall, Event
Duration, and Total Flow. The rationale for selecting these parameters is discussed in the
Appendix.
In addition to analytical monitoring, the draft permit specifies qualitative (visual) monitoring of
each stormwater outfall for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan and assessing new sources of stormwater pollution. Qualitative monitoring
parameters include color, odor, clarity, floating and suspended solids, foam, oil sheen, and other
obvious indicators of stormwater pollution.
Additional monitoring and reporting requirements include:
a. The Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis.
Implementation of the plan shall include documentation of all sampling, measurements,
inspections and maintenance activities and training provided to employees. Such
documentation shall be kept on -site for a period of five years and made available to DWQ
immediately upon request. If DWQ determines that a Plan does not meet requirements of the
permit, the permittee must give DWQ a time schedule for modifying the Plan and certify that
the Plan has been so modified.
b . Self -inspections of the facility and all stormwater systems shall occur at a minimum on a
semiannual schedule. The inspections and any subsequent maintenance activities performed
shall be documented, recording date and time of inspection, individual(s) making the inspection
and a narrative description of the facility's stormwater control system, plant equipment and
systems. Records of these inspections shall be incorporated into the Plan.
c. A log of the sampling results and activities taken to implement BMPs associated with the
vehicle maintenance activities shall be maintained and incorporated into the Plan.
d. Sample collection and qualitative monitoring shall be performed at all stormwater discharge
outfall locations. A facility with multiple discharge locations which are substantially identical
may petition DWQ to allow sampling of a reduced number of outfalls. Visual observations
shall be,recorded for all outfall locations.
e. For purposes of stormwater sampling, all samples shall be collected from a discharge resulting
from a representative. storm event. If the stormwater runoff is controlled by a detention pond, a
grab sample of the discharge from the pond shall be collected within the first 30 minutes of
discharge. If the detention pond discharges only in response to a storm event exceeding a ten
Page 5 of 10

year design storm, then no analytical monitoring is required and only qualitative monitoring
shall be performed.
If the detention pond detains the runoff generated by a one inch rainfall for 24 hours,
collect a grab sample of the discharge from the pond within the first 30 miriutes of the
discharge.
ii If the detention pond discharges only, in response to a ten-year design storm, visual
observation is required but analytical sampling shall not be. required.
iii. If the detention pond discharges only in response to a storm event exceeding a 25-year,
24-hour storm, the pond is considered to be a non -discharging stormwater control system
and not subject to NPDES permitting unless the discharge causes a violation of water
quality standards.
4. EFFECTIVE DATE OF PROPOSED COMPLIANCE SCHEDULE
Permittees covered by this General Permit shall comply with Final Limitations and Controls
specified for stormwater discharges in accordance with the following schedule:
Existing Facilities: The Stormwater Pollution Prevention Plan shall be developed and
implemented within 12 months of the effective date of the initial certificate of coverage
issued pursuant to this general permit and updated thereafter on an annual basis.
Secondary containment, as specified in Pan II, Section A, Paragraph 2(b) of this permit,
shall be accomplished within 12 months of the effective date of the initial certificate of
coverage.
Proposed Facilities: The Stormwater Pollution Prevention Plan shall be developed and
implemented prior to the beginning of discharges from the operation of the industrial
activity and be updated thereafter on an annual basis. Secondary containment, as specified
in Part II, Section A, Paragraph 2(b) of this permit shall be accomplished prior to the
beginning of discharges from the operation of the industrial activity.
5. PROPOSED SPECIAL CONDITIONS
If a facility that is required to perform the Total Toxic Organics MO) monitoring develops a
solvent management plan and make the certification detailed in the permit they will not be required
to perform the TTO monitoring.
6. BASIS FOR PROPOSED CONTROLS AND L511TATIONS
The conditions of this draft general permit have been designed using best professional judgment to
achieve water quality protection through compliance with the technology -based standards of the
Clean Water Act (Best Available Technology [BAT] and Best Conventional Pollutant Control
Technology [BCT]). Where the Director determines that a water quality violation is occurring and
water quality -based controls or effluent limitations are required to protect the receiving waters,
coverage under the general permit shall be terminated and an individual permit will be required.
Based on a consideration of the appropriate factors for BAT and BCT requirements, and a
consideratioq of the factors discussed below in this fact sheet for controlling pollutants in
stormwater discharges associated with the activities as described in Item 1 (Types of Discharge
Covered), the draft permit proposes a set of requirements for developing and implementing
stormwater pollution prevention plans, and proposes specific requirements for monitoring and
reporting on stormwater discharges.
Page 6 of 10

The draft permit conditions reflect the Environmental Protection Agency and the North Carolina
pollution prevention approach to stormwater permitting. The quality of the stormwater discharge
associated with an industrial activity will depend on the availability of pollutant sources. This draft
general permit proposes that implementation of Best Management Practices (BMPs) and traditional
stormwater management practices which control the source of pollutants meets the definition of
BAT and BCT. The draft permit conditions are not numeric effluent limitations, but rather are
designed to be flexible requirements for developing and implementing site specific plans to
minimize and control pollutants in the stormwater discharges associated with the industrial activity.
Title 40 Code of Federal Regulations (CFR) Part 122.44(k)(2) authorizes the use of BMPs in lieu
of numeric effluent limitations in NPDES permits when the agency finds numeric effluent
limitations to be infeasible. The agency may also impose BMP requirements which are
"reasonably necessary" to carry out the purposes of the Act under the authority of 40 CFR
122.44(k)(3). The conditions of the draft permit are proposed under the authority of both of these
regulatory provisions. The pollution prevention requirements (BMP requirements) in this permit
operate as limitations on effluent discharges that reflect the application of BAT/BCT. This is
because the BMPs identified require the use of source control technologies which, in the context of
this general permit, are the best available of the technologies economically achievable (or the
equivalent BCT finding).
All facilities covered by this stormwater general permit must prepare, retain, implement, and (at a
minimum of annually) update a stormwater pollution prevention plan. The term "pollution
prevention" distinguishes this source reduction approach from traditional pollution control
measures that typically rely on end -of -pipe treatment to remove pollutants in the discharges. The
plan requirements are based primarily on traditional stormwater management, pollution prevention
and BMP concepts, providing a flexible basis for developing site -specific measures to minimize
and control the amounts of pollutants that would otherwise contaminate the stormwater runoff.
The pollution prevention approach adopted in the stormwater pollution prevention plans in the draft
permit focuses on two major objectives: 1) to identify sources of pollution potentially affecting the
quality of stormwater discharges associated with industrial activity from the facility; and 2) to
describe and ensure that practices are implemented to minimize and control pollutants in stormwater
discharges associated with industrial activity from the facility and to ensure compliance with the
terms and conditions of this permit.
The Division believes that it is not appropriate, at this time, to require a single set of effluent
limitations or a single design or operational standard for all facilities which discharge stormwater
associated with industrial activity. Rather, this permit establishes a framework for the development
and implementation of site -specific stormwater pollution prevention plans. This framework
provides the necessary flexibility to address the variable risk for pollutants in stormwater
discharges associated with the industrial activities that are addressed by this permit, while ensuring
procedures to prevent stormwater pollution at a given facility are appropriate given the processes
employed, engineering aspects, functions, costs of controls, location, and age of facility (as
discussed in 40 CFR 125.3). This approach allows flexibility to establish controls which can
appropriately address different sources of pollutants at different facilities.
In 1979, EPA completed a technical survey of industry best management practices (BMPs) which
was based on a review of practices used by industry to control the non -routine discharge of
pollutants from non -continuous sources including runoff, drainage from raw material storage
areas, spills, leaks, and sludge or waste disposal. This review included analysis and assessment
of published articles and reports, technical bulletins, and discussions with industry representatives
through telephone contacts, written questionnaires and site visits.
Page 7 of 10

The technical survey identified two classes of pollution control measures. The first class of
controls are those management practices which are generally considered to be essential to the
development of an effective and efficient BMP program, low in cost, and applicable to broad
categories of industries and substances. These controls include the following: developing a Spill
Control Committee and implementing spill reporting, material inventorying and compatibility
reviews, employee training, visual inspections, preventative maintenance programs, good
housekeeping, and addressing security issues. These practices are broadly applicable to all
industries and can be implemented by each facility independent of the category of industry,
ancillary sources, specific chemicals used at different sites, and/or plant site locations. The survey
concluded that these controls should be minimum requirements for any effective BMP program.
The second class of controls are management practices which provide for a second line of defense
against the release of pollutants. These controls include prevention measures, containment
measures, mitigation and cleanup measures and treatment methods. The types of chemicals,
industrial operations and various ancillary sources specify the controls applicable to an individual
facility.
The EPA and NPDES States have, on a case -by -case basis, imposed BMP requirements in
NPDES permits. The EPA has also continued to review and evaluate case studies involving the
use of BMPs and the use of pollution prevention measures associated with spill prevention and
containment measures for oil. The development of the NPDES permit application requirements for
stormwater discharges associated with industrial activity resulted from the evaluation and
identification of the potential contaminants and the resultant water quality impacts of stormwater
discharges from industrial sites. Public comments received during the rule making provided
additional insight regarding stormwater risk assessment, as well as appropriate pollution
prevention and control measures and strategies. During that time EPA again reviewed stormwater
control practices and measures. These experiences have shown the Division that pollution
prevention measures such as BMPs can be appropriately used and that permits containing BMP'
requirements can effectively reduce pollutant discharges in a cost-effective manner. BMP
requirements are being appropriately imposed in general permits in lieu of numeric effluent
limitations pursuant to 40 CFR 122.44(k)(2).

Rationale for NCG030Ws Monitoring Requirements
When the NCG030000 general stormwater permit was initially developed and issued
back on September 1,1992 there was no stormwater monitoring data to use for permit
development. Therefore, the permit writers used the only data available at the time to monitor
from, EPA's Effluent Guidelines for the process wastewater at these operations. The
parameters that were required to be monitored in the original draft came directly from the
parameters listed for these types of facilities in their effluent guidelines.
Soon after the Federal stormwater permitting program began the EPA gave groups of
industries the option of filing group stormwater applications. These applications were required
to contain extensive stormwater monitoring data. The EPA used this data to help them develop
the multi -sector permit. It is a compilation of this data from various metal fabrication industries
through the country in the following EPA Group Data Monitoring Data Sununary.
This data in combination with the data that the North Carolina DWQ collected over the
years from the monitoring reports received from the facilities that have been permitted was
examined to determine exactly which parameters were of concern coming from the stormwater
discharging from metal fabrication facilities.
As can be seen from the data, TSS and Lead appeared in the monitoring data at
concentrations that exceeded the benchmark concentrations, and will therefore continue to be
monitored for in the renewed NCG030000 stormwater general permit. pH will also continue to
be monitored for because it is an easily performed analysis whose results may indicate the
presence of other pollutants in the stormwater discharge.
Total Toxic Organics (TTO) will also continue to be monitored because there was not
enough data collected to make a determination. Permittees will continue to be given the option
not to monitor for TTO's if they implement a solvent management plan. The Division would
prefer that permittees follow a solvent management plan because a properly followed plan
reduces the potential of these solvents getting into stormwater.

03 State Comparison
Following is a comparison of what parameters were required to be monitored for in the initial
NCG030000 general stormwater permit, Alabama's general stormwater permit,
the revised NCG030000 general stormwater 26rmit, and EPA's multi -sector pe It.
Mississippi's stormwater permit was also examined, and they had no monitoring requirements.
Alabama's list of parametersto monitor for is much more extensive because the
also Include stormwater from rime metal facilities in their general stormwater permit.
The EPA's cutoff concentrations also differ slightly from our benchamarks, which accounts for these
differences. The rationale for the difference between the initial NCG030000
permit and
the renewed
permit is discussed in the previous section.

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 .0100, stating the reasons supporting the request. Any application for an individual permit
should be made at least 180 days prior to commencement of discharge.
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.
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. Such
discharges shall be controlled, limited and monitored as specified in this permit.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater 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.
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.
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:
1. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(c) 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.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 5.
2. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the
following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
Part II Page 1 of 7

Permit No. NCG030000
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, the stormwater management plan shall document the feasibility of
diverting 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 III 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 are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices [which shall be secured with a locking
mechanism] and any stormwater that accumulates in the containment area shall be at
a minimum visually observed for color, foam, outfall staining, visible sheens and
dry weather flow, prior to release of the accumulated stormwater. Accumulated
stormwater shall be released if found to be uncontaminated by 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) BAP 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 stor nwater
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.
(d) Inspection Schedule. Schedules for inspection of stormwater conveyances,
controls, and measures to be taken to limit or prevent erosion associated with the
stormwater systems.
3. 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 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 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 that have the potential to contaminate stormwater runoff. Facility personnel (or
team) responsible for implementing the training shall be identified.
Part II Page 2 of 7

Permit No. NCG030000
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.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the 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 that the changes have
been made.
8. Facility Inspections.. Inspections of the facility and all stormwater systems shall occur at a
minimum on 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)
malting the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part U of this permit shall be
performed in addition to facility inspections.
9. Implementation. Implementation of the plan shall include documentation of all monitoring,
measurements, inspections and maintenance activities and training provided to employees,
including the log of the sampling data and of activities taken to implement BMPs associated
with the industrial activities, including vehicle maintenance activities. Such documentation
shall be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
During the period beginning on the effective date of the permit and lasting until expiration, the Permittee is
authorized to discharge stormwater. 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.

1 Measurement Frequency: Once per year during a representative storm event. A year is defined as the 12 month period
beginning on the month and day of issuance of the Certificate of Coverage.
2 If the stormwater runoff is controlled by a stormwater detention pond a grab sample of the discharge from the pond shall be
collected within the first 30 minutes of discharge. If the detention pond discharges only in response to a storm event
exceeding a ten year design storm, then no analytical monitoring is required and only qualitative monitoring shall be
performed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall
status has been granted
4 For each sampled representative storm event the total precipitation, storm duration, and total flow must be monitored.
Total flow shall be either; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the
amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the measurement of flow at
20 minute intervals during the rainfall event.
Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations,
manufacture semiconductors, manufacture electronic crystals, or manufacture cathode ray tubes. For purposes of this
permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the
facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for
semiconductor mai[ufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the
definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in
40 CFR 469.31).
Facilities that develop a solvent management plan to be 'incorporated into the Stormwater Pollution Prevention Plan
may make a request to DWQ that monitoring of total toxic organics be waived. The solvent management plan shall
include a list of the total toxic organic compounds used; the method of -disposal used instead of dumping, such as
reclamation, contract hauling, or incineration; and the procedures for assuring that toxic organics do not routinely spill
or leak into the stormwater. ' For those facilities allowed such a waiver, the discharger shall include the following
signed certification statement on the discharge monitoring report:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit
monitoring requirement for total toxic organics (ITO), I certify that to the best of my knowledge and belief, no
Part II Page 4 of 7

Permit No. NCG030000
dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater runoff
has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the
solvent management plan included in the Stormwater Pollution Prevention Plan."
6 TTO monitoring must only be performed during the first year that the permit is obtained and the last year before the
permit is renewed.

SECTION D: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
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 4. 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 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 5. 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.
