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, lubed, 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 whenever 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 through 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 that 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
SWPPP.
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 for each
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
vegetative swails and ditches are used for the conveyance of storm water to Outfalls 004 and 005.
All areas draining to these outfalls travel across sections of natural vegetation to help control
sedimentation runoff.

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 Incident/Release reports are kept on file.

Subject: RE: Elementis Chromium Stormwater Permit NCS000003
Hi Sean,
OK, I have pulled a copy of NCS000003 and can confirm that Table 2 of the permit identifies the sampling periods as
May through November (7 months) and December through April (5 months). However, I also note that footnote 2 to the
same table references a 'six-month sampling period'.
I think this internal inconsistency in the permit text is accidental, and should be resolved in favor of the six-month
footnote reference:
Our typical practice in other permits is to divide the year into two six-month periods.
There is no evidence in the permit development file to suggest a basis for this unusual arrangement.
o This arrangement is so unusual, that I would certainly expect the permit writer to have made a written
note of the basis for this arrangement when the permit was renewed. There is no such note in the file.
So, here's what I think Elementis Chromium you should do:
• Please consider that the sample you obtained in May 2012 is for Sampling Period 4 (erroneously noted as Dec
1, 2011— April 30, 2012 in Table 2 of the permit); do not send us your'No Discharge This Period' report.
• Please obtain a second semi-annual sample before the end of the year 2012.
• Please send us a written request to revise your sampling schedule to two six-month periods per year.
• Note: I've arranged these recommendations so that we can switch to a January —June period, and a July —
December period. I'm trying to take advantage of the provisions in North Carolina rule that give us the freedom
to make minor modifications to an individual stormwoter permit on two counts: in the case of an obvious minor
error like a typo, and in the case of minor modifications to a sampling program, without going through the whole
administrative processes that usually attend a permit modification. I'm trying to set you up with a corrected, and
easy to remember schedule.

• Once we receive your request, we will send you a letter amending your permit schedule through April of 2015;
and we will incorporate the corrected schedule into the revised text at the next renewal of your permit (in April
2015.)
• 1 would like to give Linda Willis the opportunity to object to these changes, if it turns out that she has
information suggesting that the permit sample periods were deliberately set up as 5 months and 7 months.
Linda, any objection/comment?

Ken,
We spoke earlier today retarding the Elementis Chromium Stormwater permit (NCS000003) monitoring schedule. I
recently noticed that the monitoring schedule listed in the permit has a 7 month monitoring period for odd sample
numbers and a 5 month monitoring period for even sampling numbers. According to the monitoring schedule, the
monitoring period for sample number 4 ended April 30. We collected sample number 3 at the end of the monitoring
period, so we only had three months to collect the sample because we are required to wait 60 days between samples. I
was going to report non -discharge for the period; however, we did collect a stormwater sample in May, so technically we
have collected a stormwater sample within a six month period. Can you please respond with your advice on how to
proceed (ie should we submit non -discharge for the period or should we submit the May sample as period 4 sample and
modify the monitoring schedule to reflect a 6 month monitoring period)? If you have any questions, please do not
hesitate to contact me on my cell phone [phone]). Thank you.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000003
Elementis Chromium Castle Hayne Kant
New Hanover County
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-atmually 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 specifies: 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 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.

Mr. Sean Coury
Elementis Chromium Castle Hayne Plant
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 II Section B. Qualitative monitoring is required regardless of
representative outfall�sfatus:'.:
6. You are responsible for all 'rnonitc ring 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. ( lie 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. 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 m—p 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 I1
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 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 Ainnual 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 botton; of this page. If no adverse comments are
received from the public or horn you, this permit will likely be issued in about two months.

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 LII, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum. the following items:
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 3.
3. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
Part It Page I of 6

Permit No. NCS000003
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 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) 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.
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
Part If Pagc 2 of 6

Permit No. NCS000003
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.
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 3) to the Director that the changes
have been made.
S. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in 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 It of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
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.

periods.
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.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 3. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
In the event an atypical condition is noted at a stormwater 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 Stormwater Pollution Prevention

RE: Elementis Chromium Stormwater Permit NCS000003
Thanks Linda and Ken,
I will proceed with submitting the sample collected in May as sample number 4 instead of no -discharge. Ken, how should
I proceed with getting the sample schedule modified in the permit?

Sean,
I don't have any concerns with Ken's recommendations. He's a great source of information and I use him as my think
tank quite often.

Hi Sean,
OK, I have pulled a copy of NCS000003 and can confirm that Table 2 of the permit identifies the sampling periods as
May through November (7 months) and December through April (5 months). However, I also note that footnote 2 to the
some table references a 'six-month sampling period'.
I think this internal inconsistency in the permit text is accidental, and should be resolved in favor of the six-month
footnote reference:
Our typical practice in other permits is to divide the year into two six-month periods.
There is no evidence in the permit development file to suggest a basis for this unusual arrangement.
o This arrangement is so unusual, that I would certainly expect the permit writer to have made a written
note of the basis for this arrangement when the permit was renewed. There is no such note in the file.
So, here's what I think Elementis Chromium you should do:
• Please consider that the sample you obtained in May 2012 is for Sampling Period 4 (erroneously noted as Dec
1, 2011— April 30, 2012 in Table 2 of the permit); do not send us your 'No Discharge This Period' report.
• Please obtain a second semi-annual sample before the end of the year 2012.
• Please send us a written request to revise your sampling schedule to two six-month periods per year.
• Note: I've arranged these recommendations so that we can switch to a January —June period, and a July —
December period. I'm trying to take advantage of the provisions in North Carolina rule that give us the freedom
to make minor modifications to an individual stormwater permit on two counts: in the case of an obvious minor
error like a typo, and in the case of minor modifications to a sampling program, without going through the whole
administrative processes that usually attend a permit modification. I'm trying to set you up with a corrected, and
easy to remember schedule.
• Once we receive your request, we will send you a letter amending your permit schedule through April of 2015;
and we will incorporate the corrected schedule into the revised text at the next renewal of your permit (in April
2015.)
• 1 would like to give Linda Willis the opportunity to object to these changes, if it turns out that she has
information suggesting that the permit sample periods were deliberately set up as 5 months and 7 months.
Linda, any objection/comment?
Ken

Subject: Elementis Chromium Stormwater Permit NCS000003
Ken,
We spoke earlier today retarding the Elementis Chromium Stormwater permit (NCS000003) monitoring schedule. I
recently noticed that the monitoring schedule listed in the permit has a 7 month monitoring period for odd sample
numbers and a 5 month monitoring period for even sampling numbers. According to the monitoring schedule, the
monitoring period for sample number 4 ended April 30. We collected sample number 3 at the end of the monitoring
period, so we only had three months to collect the sample because we are required to wait 60 days between samples. I
was going to report non -discharge for the period; however, we did collect a stormwater sample in May, so technically we
have collected a stormwater sample within a six month period. Can you please respond with your advice on how to
proceed (le should we submit non -discharge for the period or should we submit the May sample as period 4 sample and
modify the monitoring schedule to reflect a 6 month monitoring period)? If you have any questions, please do not
hesitate to contact me on my cell phone [phone]). Thank you.
