PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The'Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this 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
stonnwater 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 storm 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 slate'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 [nap drawn to scale (including a distance legend) showing: the site property
boundary, the stonnwater 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.
(e) Certification that the stonnwater 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 Ill, Standard Conditions, Section
Part II Page 1 of 9

Perniit 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. 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 stonnwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the pennittee 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 stonnwater 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
313 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 stonnwater 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 stonnwater 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 stonnwater 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
PartII Page 2 ot9

Permit No. NCS000003
person shall be on -site at all times during facility operations that have the potential to
contaminate stornwater 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 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, stonnwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural.BMPs. The
program shall establish schedules of inspections, maintenance, and housekeeping
activities of stonnwater control systems, as well as facility equipment, facility areas, and
facility systems that present a potential for stonnwater exposure or stonnwater pollution.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stonnwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained..
6. Responsible Party. The Stonnwater 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 pennittee 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-stornnvater 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 pennittee when the Plan does not meet one or more of the
minimum requirements of the pennit. Within 30 days of such notice, the pennittee shall
Part I I Page 3 of 9

Permit No. NCS000003
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permitter shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, including the log of the sampling data and
of actions 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 the Director's authorized representative
immediately upon request.

Permit No. NCS000003
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stonnwater 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 stonnwater 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 storm 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
producing a discharge begins within 10 hours.

Permit, the permittee has submitted an application for renewal of coverage before the submittal deadline,
the pennittee will be considered for renewed coverage. The applicant must continue semi-annual
monitoring until the renewed pennit is issued.
2 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.
The pennittee shall report the analytical results from each sample within the monitoring period. The
pennittee shall compare monitoring results to the benchmark values in Table 3. The benchmark
values in Table 3 are not permit limits but should be used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP). Exceedences of benchmark values require the
pennittee to increase monitoring, increase management actions, increase record keeping, and/or
install stonnwater Best Management Practices (BMPs) in a tiered program. See below the

the date and value of the benchmark exceedence, the inspection date, the personnel conducting the
inspection, the selected actions, and the date the selected actions were implemented.
Tier Two
If: During the term of this permit, the first valid sampling results from two consecutive monitoring periods
are above the benchmark values, or outside of the benchmark range, for any specific parameter at a
soecific discharge outfall:
Then: The permittee shall:
1. Repeat all the required actions outlined above in Ticr One.
2. Immediately institute monthly monitoring for all parameters at every outfall where a sampling result
exceeded the benchmark value for two consecutive samples. Monthly (analytical and qualitative)
monitoring shall continue until three consecutive sample results are below the benchmark values or
within the benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Maintain a record of the Tier Two response in the Stonnwater Pollution Prevention Plan.
During the term of this pennit, if the valid sampling results required for the permit monitoring periods
exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any specific
outfall on four occasions, the permittee shall notify the DWQ Regional Office Supervisor in writing within
30 days of receipt of the fourth analytical results. DWQ may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for the remainder
of the permit;
• require the pennittec to install structural stom ater controls;
• require the pennittee to implement other stonnwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure Exclusion.

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 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
stormwater pollution.
In the event an atypical condition is noted at a stonnwater discharge outfall, the penmittee 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.

Permit: NCS000003 Owner • Facility: Elementis Chromium L P
Inspection Date: 02/03/2010 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
The site has an outfall not identified on the SWP3 map. The outfall is located on the northeast corner of the impervious
area (north of rxr tracks). The area is used for staging area for chrome ore for processing. The impervious area can hold
a significant amount of stormwater (it is in a depression) before discharging through a swale covered with scrap metal.
Behind the scrap metal (wetland side) the area drains out a discrete discharge point that would be a better location for
sampling. The Central Office permit writer (Brian Lowther) agreed with RO representative that this should be the only
outfall monitored as the other two that are currently being monitored are sampled with the comingling of surface waters or
discharges from the adjacent Martin Marietta mine. Elementis is hereby authorized to sample this new outfall and
eliminate sampling at the two existing. There may be another outfall draining the parking area. Due to TSS issues from
the impervious parking area, this outfall should not be sampled but the outfall should be located on monitored
qualitatively. Qualitative monitoring is required at all outfalls regardless of representative outfall status.
Compliance sampling was conducted at the two outfalls presently being monitored. Hexavalent chrome was monitored.
None was detected.
The facility was very clean, no evidence of illicit discharges at any of the outfalls.

Comments: NOTE: Linda thanks for calling to let us know in advance about the collection of the sample and its estimated delivery
time. However, the following is for your information only: as you know the analysis holding time is 24-hour however, samples
delivered to our receiving unit at 8:20 (2/4/10). It took about an hour (very reasonable time) in processing and checking at receiving
—unit prior to samples-actually-received-at-its-final-destination-W et-Chem-group-Finally,-we-have-left-with-I-hour-and-40 min -to -meet
the holding time but with these types of analysis includingjust preparation and analysis with no time to waste, it will take about 4 to
4.5 hours. As you can see, there is no way we could have met that with about 98% of analysis accuracy.
Corrective Action:)) If it is possible, please collect these types of samples late in the afternoon perhaps make special
arrangement with your carrier or avalible delivery recourses.

Comments: MOTE: Linda thanks for calling to let us know in advance about the collection of the samples and its estimated delivery
time. However, the following is for your information only: as you know the analysis holding time is 24-hour however, samples
delivered to our receiving unit at 8:20 (2/4/10). It took about an hour (very reasonable time) in processing and checking at receiving
—unit-prior to samples -actually-received-at-its-final-destination-W et -Chem -group -Final ly-we-have-left-with-2-hour-and-l2-min-to-meet
the holding time but with these types of analysis including just preparation and analysis with no time to waste, it will take about 4 to
4.5 hours. As you can see, there is no way we could have met that with about 98% of analysis accuracy
Corrective Action:1) If it is possible, please collect these types of samples late in the afternoon perhaps make special
arrangement with your carrier or avalible delivery recourses.
2) Sample will be qualified with Q2.
❑Samples were rejected by DWQ Lab. Authorized by: Date:

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.
