Central Office Review Summary:
Owner's Other Permits:
• NC0003875 - Elcmcntis Chromium L P Castle- 1 MGD
CAA — 3712900055, NE144629
2. General Observations:
• TRI'releases include Chromium Compound, Load, and Mcrcury.
• 2 Outfalls — Natural vegetative swalcs and ditches are used to convey storniwater to Outfalls 004 and
005.
• Quarry on -site dug by nearby company fin' building materials.
• Stonnwater that falls in process areas of the plant is either collected and used in the process or drained
to an internal storm water system for treatment before being discharged through permitted industrial
discharges. Process areas are designed to contain any stormwater that falls on them. 'These designs include
curbed process areas, lined trench systems, paved roadways and areas beneath pipe racks, an internal
stormwater collection system, and grading designed to prevent runoff.
• Materials are stored to prevent leaks and reduce the possibility of runoff to stormwater discharges.
This includes adequate secondary containment for all product, fuel, and process storage tanks and storing all
containers, drums, and bags in covered warehouses to prevent exposure to the weather.
• Chromium exists in three distinct forms or valency states,metallic, trivalent and hexavalent. The
hazards and practices relating to managing the risk vary depend ng on the form present. Metallic chromium,
present in chromium -plated objects and alloys such as stainless steels, is essentially inert. Trivalent
compounds occur naturally in the environment in mineral ores, are the most stable and are not classified as
hazardous. Commercial uses include pigments, refractories and leather tanning.
• Notes show they want to change fuel source. Currently use fuel oil and chrome ore to heat. furnace.
They want to change to coal. So they will have to store coal on -site. From the site visit we learned they have
no current plans for coal because the price of fuel oil went down. They understand that their SPIT plan
must hrchrde coal piles if they do store coal. WiRO Nov 2006: Inspection. No objections to coal storage.
There is a rail spur on property that the coal will be stored near. They used coal in the early 90s. The is a
concrete pad and conveyor belt in place. Drains to detention pond and dischages with stormwater (from
BG notes 5/30/08 Michelle Mayfield URS Corp. ('919) 461-1355.)
• From httf)://www.elementiscliromium.com/hse/benefits.litm
licxavalent chromium compounds do have recognized hazards and are regulated accordingly. They occur in
the primary manufacturing process and are used in some downstunm process industries, such as chromium
plating. F,lementis Chromium works to manage these hazards responsibly during manufacture and for the
purposes of distribution.
• Our chromium chemicals can be found in a wide range of everyday items:
o plumbing fixtures, car accessories and domestic appliances such as kettles and toasters are chrome
plated
o ingredient of products applied to protect timber used to build bridges, utility poles, marine piles and
many other indttstrial applications.
o super -alloys used in aircraft engines and land based turbines contain
o chromium metal made from chromic oxide. In addition chromic oxide is used in applications to
colour ceramics, surface coatings, cosmetics, plastics and construction products
o chrome sulphate tans leather used to make clothing and shoes
o sodium sulphate is an ingredient in washing powders
3. Impairment: The Northeast Cape Fear River is on the 2006 303(d) list for a Mercury Fish Advisory and the
Northeast Cape Fear River (18-74-(25.5)) is on the 2008 draft 3003d list for impaired ccological/biological
integrity. The 2010 draft 303d list does not include the Northeast Cape Fear River 18-74-(47.5). The 2005
Basinwide Plan recommendations putting the Northeast Cape Fear River on the 303d list for the fish
consumption category. Tire river from NC210 to Ness Creek is not rated for aquatic life because dissolved

oxygen was below 4mg/I in 23 and 10 percent ofsemples. The Northeast Cape Pcar River is classified as B; Sw,
which acknowledges natural characteristics of swamps such as low dissolved oxygen.
4. Threatened and Endangered: Based on the Natural Heritage virtual workroom there are no federal protected
aquatic species within two miles of the facility. The only endangered species the Picoidcs borealis (Red -
cockaded Woodpecker).
5. Location: B; Sw
6. Industrial Chances Since Previous Permit: Changes included with the application included:
Quarry Stormwater Management Improvements- The elevation of the dike around Quarry
Section 42 was increased. The project was issued a Stormwater Project Permit No. SW8970922
Modification.
2. Elimination of Outfall 003- Outfall 003 was an outfall from rinsing dust and dirt from
employees' vehicles. The rinse water is now being collected in a sump and pumped to the
industrial wastewater treatment plant.
Analytical Monitoring, Notes: There were five samples included in the renewal application from 12/4/02 to
10/25/03 for outfalls 004 and 005, All of the samples were below the current benchmarks. Chromium was
below the detection limit for all of the samples.
Current outfalls are located in swampy areas and are not truly representative of stormwater leaving the site.
Based on the site visit (2/3) another outfall should be added to do the analytical monitoring. The outfall is
located by one of the chromium ore pills and the capped lagoon.
Total Chromium will remain in the permit because of the ore stored onsite. Chromium IV was considered bill
since all the stormwater in the process area is collected in the waste water it was not added. It should be
included in their wastewater permit.
This industry (SIC 2819) is covered in the EPA General Muhi-Scctor Permit under Subscctor C2. Industrial
Inorganic Chemicals. The pcnnit recommends monitoring ibi- Total Ahnninunt, Total Iron, and Nitrate plus
Nit ite Nitrogen. Total Aluminum and Total Iron will not be added into the renewal permit because they are not
a potential pollutant on the site. Nitrate plus Nitrite Nitrogen will be maintained in the permit.
Qualitative Monitoring Notes: Visual monitoring was done nine times at both outfalls. Outfall 004 was
clear/brown but showed no signs of pollutants. The color of Outfall 005 looked to have tannins in it and had
some leaves in the discharge.

Revised Permit Recommendations: Analytical Monitoring:
I. Maintain monitoring for total Chromium and Nitrate plus Nitrite Nitrogen. See rational above.
2. pl-I has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section B. The pennittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the pennittee must submit a monitoring report indicating "No Plow" within 30 clays
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the pennittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part lI Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
S. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A. -
2. Additional requirements for the Stormwater Management Plan have been specified in Part I1 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CPR § I22.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information
is provided in Part I Section A.

Site Visit on February 3, 2010 with Linda Willis (Wilk 0), Brian Lowther (CO) and Scan Coury [phone]
Sean Coury showed us the two outfalls, the Cape Fcar River, and some of the industrial activities onsitc. We walked
the perimeter of the site. As the application stated, almost all of the stormwater in the production area is collected
and goes to their wastewater outfall. Oulfalls 004 and 005 were both located in swampy areas. Another potential
outfall was located on the site new one of the chromium ore piles and the capped lagoon. We recommended he add
that outfall for analytical monitoring and stop sampling 004 and 005 because they are commingled in the swamp
water.

B, Paragraph 5. The pemnittee shall re -certify annually that the stonnwater
outfalls have been evaluated for the presence of non-stonnwater discharges.
3. Stonnwater 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 stonnwater, including structural and
nonstructural measures. The stonnwater 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 pennittee shall
prevent exposure of all storage areas, material0handling operations, and
manufacturing or fueling operations. In�a`reasgrhere elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away fro ;areas of p tential contamination.
(b) Secondary Containment RequiremerSYs.atnd Records. Secondary containment is
required for: bulk storage of ligpid matefals; storage in any amount of Section
313 of Title lll of the Superfudd Amenam nts and Reauthorization Act (SARA)

containment areas shall;be.5naintained. if the secondary containment devices are
connected to stormwate conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with ail' ckingmechanism), and any stonnwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
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 the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part 11 Page 2 of 9

Permit No. NCS000003
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 stonnwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,

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.
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. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The 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

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous stonn event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producink a discharge begins within 10 hours.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stonnwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stonnwater Pollution Prevention Plan (SPPP) and assessing new sources of
stonnwater pollution.
In the event an atypical condition is noted at a stonnwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the SPPP.

SECTION C: OPERATION ANDtN AINTENANCE OF POLLUTION CONTROLS
Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment and
control (and related appurtenances) which are installed or used by the pennittee to achieve compliance with
the conditions of this individual permit. Proper operation and maintenance also includes adequate
laboratory controls and appropriate quality assurance procedures. This provision requires the operation of
back-up or auxiliary facilities or similar systems which are installed by a pernittee only when the operation
is necessary to achieve compliance with the conditions of this individual permit.
2. Need to Halt or Reduce Not a Defense
It shall not be a defense for a pennittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this individual permit.
3. Bvpassine of Stormwater Control Facilities
Bypass is prohibited and the Director may take enforcement action against a pennittee for bypass unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Pennittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public ii formation in accordance with Part 111, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
I . Site Plan. The site plan shall provide a do scription 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 stonnwater
outfall(s) discharges, or if the discharge is to a municipal separate stone sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the point(s) of discharge. The general location
map (or alternatively the site map) shall identify whether each receiving water is
impaired (on the state's 303(d) list of impaired waters) or is located in a
watershed for which a TMDL has been established, and what the parameter(s)
of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stonnwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(c) 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
Part II Page 1 of

Permit No. NCS000003
B, Paragraph 5. The pennittee shall re -certify annually that the stonnwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stonnwater 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 stonnwater, including structural and
nonstructural measures. The stonnwater 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 stonmvater. Wherever practical, the pctmittec 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 stonnwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary, containment is
required for: bulk storage of liquid materials; storage in any amount of Section
31-3 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances;•in
order to prevent leaks and spills from contaminating stormwater runoff. A table.
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a locking mechanism), and any stonnwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stonnwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stonnwater discharges and data collected
through monitoring of stonnwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be.performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the tens of
the permit at each stormwater discharge outfall (SDO)..
A representative storm event is a storm event that measures greater lh"ui 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greatej . than0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be.collected if the next rain
producing a discharge begins within 10 Hours.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000003
Elementis Chromium Castle Hayne Plant
New Hanover County
Dear Mr. Coury:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
A site visit was conducted on February 3, 2010. The two current sampling locations are taken "in stream"
and are therefore diluted and not representative of stormwater leaving the site. During the site visit another
outfall was identified that was not in the SPPP. This outfall appears to be the one that should be
representative of stormwater on the site. We recommend discontinuing of monitoring at the previous two
outfalls.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters, Chromium and Nitrate plus Nitrite Nitrogen, have been added to this
permit.
2, pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. If the
sampling results are above a benclunark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If during the tern of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter at a specific discharge outfall two times in a row (consecutive), then the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier 1 and also immediately institute
monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.

Permit No. NCS000003
5. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part It Section B. Qualitative monitoring is required regardless of
representative outfall status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If the
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. 1-tie plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Armual Summary
DMR copy must be submitted to the local DWQ Regional Office by March 1 of each year.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should.be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at (919) 807-.6368 or

order to prevent leaks and spills rfrom contaminating stormwater runoff. A table
or summary of all sucfi�tanks and stored materials and their associated secondary
containment areas -shall be•maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a((locking.mechanism), and any stormwater that accumulates in the
containment area -shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stonnwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stonnwater discharges and data collected
through monitoring of stonnwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
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 the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part 11 Page 2 of 9

Permit No. NCS000003
person shall be on -site at all times during facility operations that have the potential to
contaminate stonnwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stonnwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) maybe a component of the SPRP,
but may not be sufficient to completely address the stonnwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stonnwater control systems, stornwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,

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.
Plan Amendment. The pennittce 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. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stonnwater outfalls have been
evaluated for the presence of non-stonnwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stonnwater Management Plan.

BEST MANAGEMENT PRACTICE (BMP) IDENTIFICATION
The Castle Hayne Plant is dedicated to prevent, mitigate, or eliminate storm water pollution
through the use of Best Management Practices (BMP's) for reducing or eliminating pollutant loads
in storm water discharges from the plant. The following sections describe the Castle Hayne
Plant's BMP approach.
Currently Employed Best Management Practices
1) Good Housekeeping
The Castle Hayne Plant employs the use of Good Housekeeping practices to maintain areas,
which may contribute pollutants to storm water, discharges in a clean and orderly manner. Good
housekeeping practices are stressed in all employee training programs. The following paragraphs
describe what Castle Hayne does to insure the site is kept clean:
Operation and Maintenance: All plant personnel strive to maintain dry and
clean floors and ground surfaces in their work areas. Plant crews regularly pick
up and dispose of garbage and waste material. As part of their daily routine, all
plant personnel make sure that equipment is working properly and inspected for
leaks or conditions which could lead to discharges of chemicals or contact of
storm water with raw materials, intermediate materials, waste materials, or
products.
Employee Participation: Safe Work Permits are utilized as a means to ensure
good housekeeping standards are maintained and followed. Clean up is part of
every job and the Work Permit is not signed by Operations if the job site is not
cleaned satisfactory. Employees are also involved in the S. A. F. E. Sample
program and are encouraged to observe routine tasks and make suggestions on
improving the safety and housekeeping of those tasks.
Communications: Good housekeeping is also stressed at both informal daily
meetings. All employees are instructed to make sure their work areas are kept
clean and inspected for leaks or other conditions which might affect the quality of
storm water run-off and report such items to supervision as noted.
Inspections: Routine housekeeping inspections are made by supervision on a
regular basis though the Planned Inspection Program and random S. A. F. E.
Samples (Castle Hayne's job observation program). The inspection results are
documented and sent to the HSE Department.
2) Preventive Maintenance
The Castle Hayne Plant has a preventive maintenance program in place for its plant operations
which involves the regular inspection and testing of plant equipment and operational systems to
uncover conditions which could result in discharges of chemicals to the plant storm water
conveyance system and to the surrounding surface waters. More specifically, the Castle Hayne
Plant's preventive maintenance program includes the following areas:
Scheduled Routine Preventive Maintenance: All essential equipment such as
pumps, motors, power supply equipment, control devices, sensing and analyzing
devices, and rotating equipment are routinely tested, tubed, calibrated and

otherwise inspected to ensure their proper operation. Critical transfer piping is
routinely tested. Results are documented and noted defects are corrected as
required.
• Identification Of Equipment To Test: Various plant programs or regulatory
requirements call for the routine inspection of pipes, pumps, storage tanks and
bins, pressure vessels, pressure relief valves, process and material handling
equipment, and the process wastewater treatment facility.
• Mobile Equipment Inspections: Routine daily inspection reports are completed
on all moving equipment, including cranes, towmotors, lifts, and the switch
engine. Needed repairs made accordingly to ensure against leakage of fuel and
lubricants which might otherwise enter the Plant storm water system.
• Inspections: Scheduled, as well as unscheduled inspections, are conducted to
inspect and examine for leaks, corrosion, support or foundation distress signs, or
other form or signs of deterioration, spills, or leaks.
• Equipment Repair or Replacement: Castle Hayne's program provides for the
prompt and timely repair or replacement of any equipment found to be defective
during its inspection and testing.
• Records of Preventive Maintenance: As part of its on -going program, the
Castle Hayne Plant keeps detailed records of its maintenance operations, which
include the maintaining of a record system to schedule tests and document
inspection results. These records are retained on -site.
3) Removal, Cover, or Control of Industrial Activities
The Castle Hayne_Plant=strives_to_eliminate_wheneyer_possible=the=inclusion=of-process-area
rainfall -and runoff_from_entering=storm-water discharges. Storm water that falls in process areas
of the plant is either collected and used in the process or drained to an internal storm water
system for treatment before being discharged—throughh=permitted—industrial=discharges. To
accomplish these goals, the following practices are employed:
Process Area Design: To reduce the chances for release of materials and
chemicals which can cause storm water run-off pollution, process=areas=are
designed_to-contain=any storm=water_lhat_falls_on-them. These designs include
curbed process areas, lined trench systems, paved roadways and areas beneath
pipe racks, an internal storm water collection system, and grading designed to
prevent runoff.
Material Storage Practices: The Castle Hayne Plant employs measures to
insure the safe storage materials to prevent leaks and reduce the possibility of
runoff to Storm water discharges. These measures include providing adequate
secondary containment for all product, fuel, and process storage tanks; storing all
containers, drums, and bags in covered warehouses to prevent exposure to the
weather, providing clearly marked aisle space to facilitate easy access for
inspections; storing products away from direct traffic routes to prevent accidental
spills; stacking containers according to manufacturers' instructions to avoid
damaging containers from improper weight distribution, and storing containers on
pallets or similar devices to prevent corrosion of the containers which can result
when containers come in contact with moisture on the ground.

Material Transportation within the Plant: All hazardous material piping is run
above ground, so leaks are readily detectable and less difficult to remediate.
Areas beneath overhead piping are paved and curbed whenever possible to
catch potential leaks and prevent them from reaching groundwater or storm water
discharges. Regular inspection of this piping is an integral part of the plant's
process safety mechanical integrity program designed to prevent pipe failures.
Material Inventory Procedures: The use of sound material tracking and
inventory practices is an integral part of the Castle Hayne Plant's Stormwater
Pollution Prevention Plan (SWPPP). Such practices include identifying all
chemical substances present in the workplace, maintaining an up-to-date set of
Material Safety Data Sheets (MSDS) for each chemical; labeling all containers to
show the name and type of substance contained, clear identification and marking
on the inventory of hazardous materials using Hazardous Material Identification
System (HMIS).
4) Visual Inspections
Regular visual inspections are performed to insure that all the elements of the SWPPP are in
place and working properly. Such inspections are meant to be a routine look -over of the facility to
identify conditions, which may give rise to contamination of storm water run-off with pollutants
from the plant. Items covered by the visual inspections include areas around all process and
maintenance equipment; areas where spills and leaks have occurred in the past; material storage
areas; material handling areas; outdoor material processing areas; and waste generation,
storage, treatment and disposal areas. Formal inspections of the stormwater conveyances are
also conducted at least twice annually.
Implementation of Visual Inspection Plan: As part of its plant operations,
Castle Hayne has an on -going visual inspection program which every employee
carries out during the normal course of their duties at the plant. This program
has been expanded to cover storm water considerations.
Stormwater Conveyance Inspections: Stormwater conveyances and outfall
locations are inspected twice per year at a minimum. These inspections are
performed in conjunction with and recorded in the field notebook along with the
spring and fall visual monitoring. If erosion or other problems are found,
notifications are generated to correct any deficiencies in a timely manner. The
results of the stormwater conveyance inspection are also documented in the
SW PPP.
5) Spill Prevention and Response
The Castle Hayne Plant has developed the SPCC plan for the plant, which addresses the subject
of spill prevention and response. The purpose of the plan is to prevent and control discharges of
oil from spill events that have the potential to reach navigable waterways of both the State of
North Carolina and the United States. It details the duties and responsibilities of both trained and
non -trained responders. The plan is reviewed at least once every three years and will be
amended as necessary to include more effective spill prevention and control technology.
Highlights of the SPCC plan include:
Facility Spill History and Potential: The SPCC Plan reviews the history of
previous spills at the facility and the actions taken to prevent their recurrence.
Locations of the plant with the potential for fuel spills are also identified and spill

scenarios are described. Steps taken to reduce or eliminate such potential spills
from reaching storm water discharges are outlined.
• Storm Water Drainage, Management, and Control: The storm water drainage
locations are identified and the areas of the facility, which drain to each of them,
are defined. Measures to control the drainage patterns and prevent the
possibilities of spills reaching the storm water discharges are listed.
• Bulk Storage Tanks: All the fuel storage tanks are identified and described in
detail. Their design criteria and measures to insure their continued integrity are
outlined, as_well.as_a.description-of the-secondary_containment,provided foreach
vessel:,
• Drum Storage and Management: Drums used for the storing and dispensing of
oils and oil related materials could adversely impact the environment if they are
not managed properly. The SPCC plan describes procedures for managing
drums at the plant by defining their storage locations, secondary containment
measures, and spill cleanup plans for each transfer point.
• Unloading and Transfer Operations: The SPCC plan outlines the unloading
and transfer of fuels throughout the plant. The containment for unloading and
pumping operations are described in detail, as well as methods for inspecting
their condition, maintaining their integrity, and defining the potential for leaks and
spills throughout the system.
Inspections and Records: Two inspection programs have been developed for
the purpose of preventing releases of oil and other related petroleum products.
The first is a weekly visual inspection of the bulk storage tank, drum storage area,
and fuel transfer locations to check the physical condition of the storage vessels,
check for leaks and spills, and drain the containment structures of storm water as
needed. The second is a random maintenance inspection of the bulk storage
tanks and support structures which includes visual as well as non-destructive
testing methods. Other plant inspection programs designed to address the
operational, safety, environmental, and general working conditions of the plant's
key operating equipment are also included on a regular basis.
6) Sediment and Erosion Control
Plant areas that may be subject to routine vehicular traffic are covered with stone to minimize
erosion potential, while areas that are not exposed are grassed. Areas outside the main
production areas that have not been developed remain naturally wooded. Areas under
construction contain silt fences as needed to control sedimentation runoff.
7) Management of Runoff
All storm water falling in the process areas of the plant is either processed within the area or
collected and sent to the wastewater treatment area to be treated before discharging. Natural

s e d i m e n to d o n: ru n off

8) Employee Training
Facility personnel responsible for managing hazardous wastes, materials, and oil are required to
attend hazardous waste training. In addition, each site employee undergoes annual stormwater
pollution prevention training annually. Employee training records are maintained on site.
9) Recordkeeping
Records are maintained on site for all formal inspections, preventative maintenance work,
employee training, and visual storm water inspections. In addition, copies of all agency
correspondence and IncidenURelease reports are kept on file.

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES AT ELEMENTIS CHROMIUM
The significant changes that have occurred at the Elementis Chromium Castle Hayne Plant since the last
permit application are as follows:
1) Quarry Stormwater Management Improvements
A project was completed that increased the elevation of the dike surrounding Quarry Section #2 in order to
improve stormwater management surrounding the quarry areas and provide a greater degree of
environmental protection during extreme natural disasters, such as hurricanes. The project was issued a
Stormwater Project Permit No. SW8 970922 Modification.
2) Elimination of Outfall 003
A project was completed which eliminated Outfall 003. Outfall 003 was essentially drinking water used to
rinse dust and dirt from employees' automobiles. The rinse water is now being collected in a sump and
pumped to the industrial wastewater treatment plant. The rinse water combines with the normal
wastewater influent and is discharged after treatment to Outfall 001 (Wastewater Treatment Plant effluent
stream). The project was issued as a permit modification under NPDES Permit No. NC0003875.

PART I
MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
ECTION A: FINAL LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGE
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 below.
1. 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 II, Standard
Conditions, Section EX of this permit. The Plan shall include, at a minimum, the following
items:
a. 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:
(1) 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.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) . 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 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.
(4) 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.
(5) 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 ff, Standard Conditions, Section
B .9.

Permit No. NCS000003
b. Stonnwater 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:
(1) A study addressing 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 practicable the permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) 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
materials 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, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. 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.
(3) 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.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory
of the facility. Facility personnel (or team) responsible for implementing the plan shall be
identified in the plan. 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.
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.
e. 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
Page 5

Permit No. NCS000003
operations that have the potential to contaminate stormwater runoff. Facility personnel (or
team) responsible for implementing the training shall be identified in the Plan.
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(s) assignments provided.
Plan Ammendment. 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
II, Standard Conditions, Section B, #9) to the Director that the changes have been made.
h. Facility Inspections. Inspections of the facility and all• toimwater 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)
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.
Visual monitoring as required in I.A.2.g.(3) shall be performed in addition to facility
inspections.
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.

Permit No. NCS000003
2 Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
a. If a facility has multiple discharge locations with substantially identical stonnwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge our all locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
c. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part 11,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stonnwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant tlushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting
Page 7

Permit No. NCS000003
If the storm event monitored and reported in accordance with this permit coincides with a
non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

a. Definitions
(1) 'Bypass" means the known diversion of stormwater from any portion of a
stormwater control facility including the collection system, which is not a
designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property,
damage to the control facilities which causes them to become inoperable, or
substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does
not mean economic loss caused by delays in production.
b. Bypass Not Exceeding Limitations.
The perminee may allow any bypass to occur which does not cause limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d.
of this section.
Notice
p) Anticipated bypass. If the permittee knows in advance of the need for a
bypass, it shall submit prior notice, if possible at least ten days before the
date of the bypass; including an evaluation of the anticipated quality and
affect of the bypass.

Individual Stormwater Page Al2
(2) Unanticipated bypass. The permittee shall submit notice within 24 hours of
an unanticipated bypass as required in Part fl, E. 5. of this permit. (24-
hour notice).
Prohibition of Bypass
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury or severe
property damage;
(2) There were no feasible alternatives to the bypass, such as the use of
auxiliary control facilities, retention of stormwater or maintenance during
normal periods of equipment downtime or dry weather. This condition is
not satisfied if adequate backup controls should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which
occurred during normal periods of equipment downtime or preventive
maintenance; and
(3) The permittm submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
effects, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.

a. Definition
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset does
not include noncompliance to the extent caused by operational error, improperly
designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
Effect of an Upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met. No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
C. Conditions Necessary for a Demonstration of Upset
A permittee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other
relevant evidence that: .
(1) An upset occurred and that the permittee can identify the cause(s) of the
upset;

Individual Stormwater Page A13
(2) The permitted facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 5. (b)
(B) of this permit
(4) The permittee complied with any remedial measures required under Part II,
A. 2. of this permit.
d. Burden of Proof
In any enforcement proceeding the permittee seeking to establish the occurrence of
an upset has the burden of proof.
Samples collected and measurements taken, as required herein, shall be
characteristic of the volume and nature of the permitted discharge. Samples shall be
taken on a day and time that is characteristic of the discharge. All samples shall be
taken before the discharge joins or is diluted by any other waste stream, body of
water, or substance. Monitoring points shall not be changed without notification to
and approval of the Director.
Duplicate signed copies of all reports required herein, shall be submitted to the
following address:
Division of Environmental Management
Water Quality Section
ATTENTION: Central Files
Post Office Box 29535
Raleigh, North Carolina 27626-0535
Where required, appropriate flow measurement devices and methods consistent
with accepted scientific practices shall be selected and used to ensure the accuracy
and reliability of measurements of the volume of monitored discharges.
Test procedures for the analysis of pollutants shall conform to the EMC regulations
published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality
Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC
1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40
CFR 136.
To meet the intent of the monitoring required by this permit, all test procedures
must produce minimum detection and reporting levels that are below the permit
discharge requirements and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure. If no approved

Individual Stormwater Page A14 L
methods are determined capable of achieving minimum detection and reporting
levels below general permit discharge requirements, then the most sensitive
(method with the lowest possible detection and reporting level) approved method
must be used.
Penalties for Tampering
The Clean Water Act provides that any person who falsifies, tampers with, or
knowingly renders inaccurate, any monitoring device or method required to be
maintained under this permit shall, upon conviction, be punished by a fine of not
more than $10,000 per violation, or by imprisonment for not more than two years
per violation, or by both. If a conviction of a person is for a violation committed
after a first conviction of such person under this paragraph, punishment is a fine of
not more that $20,000 per day of violation, or by imprisonment of not more than 4
years, or both.
Records Retention
The permittee shall retain records of all monitoring information, including all
calibration and maintenance records and all original strip chart recordings for
continuous monitoring instrumentation, copies of all reports required by this
