SUPPLEMENTAL INFORMATION REQUIRED FOR RENEWAL OF INDIVIDUAL
NPDES STORMWATER PERMIT
Two copies of each of the following shall accompany this submittal in order for the application
to be considered complete:
(Do not submit the site Stormwater Pollution Prevention Plan)
Initials
1. A current Site Map ftom the Stormwater Pollution Prevention Plan. The location of
industrial activities (including storage of materials, disposal areas, process areas and
loading and unloading areas), drainage structures, drainage areas for each outfall,
building locations and impervious surfaces should be clearly noted.
T 2. A summary of Analytical Monitoring results during the term of the existing permit
(if your permit required analytical sampling). Do not submit individual lab reports.
The summary can consist of a table including such items as outfall number,
parameters sampled, lab results, date sampled, and storm event data. H
3. A swinilary of the Visual Monitoring results. Do not submit individual monitoring
reports. The summary can consist of a table including such items as outfall number,
parameters surveyed, observations, and date monitoring conducted.
�- 4. A summary of the Best Management Practices utilized at the permitted facility.
Summary should consist of a short narrative description of each BMP's in place at
the facility. If the implementation of any BMP's is planned, please include
information on these BMP's.
5. A short narrative describing any significant changes in industrial activities at the
permitted facility. Significant changes could include the addition or deletion of
work;processes, changes in material handling practices, changes in material storage
practices, and/or changes in the raw materials used by the facility.
-S- 6. Certification of the development and implementation of a Stormwater Pollution
Prevention Plan for the permitted facility (Sign and return attached form).
If the final year analytical monitoring of the existing permit term has not been completed
prior to filing the renewal submittal, then the last years monitoring results should be submitted
within 30 days of receipt of the laboratory reports. (i.e. do not withhold renewal submittal
waiting on lab results)
Representative storm sampling may now be conducted anytime during the year (tire April
to November window has been eliminated) and the representative rainfall event is now defined
as a storm event that measures greater than 0.1 inches and is preceded by at least 72 hours in
which no storm event measuring greater than 0.1 inches has occurred.

Item # 1
Site Map
The site map is enclosed separately due to its size.
Please note: The site map shows seven outfalls, numbered 1 through 7. Only five of
these outfalls actually discharge to the river, and only these five will be monitored.
Outfall 2 is not in use acid has been disconnected from all sources. Outfall 7 discharges
into Outfall 6, and so only Outfall 6 is an actual discharge point.

Item # 2

Rest Management Practices

Summary of Best Management Practices
As described in our Stormwater Pollution Prevention Plan (SPPP), the following Best
Management Practices (BMPs) are utilized at Clariant's Mount Holly West (MHW)
facility.
1. Secondary containment is provided for the bulk storage of chemicals.
2. Loading and unloading operations are conducted in paved areas that drain into the
industrial sewer, or into sumps that are pumped into the industrial sewer.
3. Secondary containment is provided around the truck scale.
4. Process areas utilize written procedures for all chemical -handling tasks.
5. Perimeter containment curbing is provided for most of the site, to provide an
additional level of protection in the event of a loss of containment.
6. Stormwater outfalls and stormwater containment areas have valves that are
normally kept closed. Only authorized employees open them, and they do so only
after inspecting the stormwater for evidence of contamination.
7. Outfalls and containment structures are inspected regularly.
8. All employees who work in chemical process areas receive training in operating
procedures, spill prevention, and spill response.
9. The site has an emergency response team (ERT) on site at all times, trained in spill
containment and mitigation.
10. In the event of any major construction activities, construction contractors are
required to have an erosion control plan.
11. A 5S program has been implemented to clean and organize work areas. This
program emphasizes housekeeping and minimizes accumulations of excess
chemicals and clutter.
12. The site has implemented a Spill Prevention Control and Countermeasures Plan
(SPCC).

Item # 5
Significant Changes in Industrial Activities

Description of Significant Changes in Industrial Activities
Activities at Clariant's Mount Holly West (MHW) facility have been relatively consistent
during the duration of the facility's existing stormwater discharge permit. Very few
changes have taken place that would be considered "significant" in terms of site activities
or their effect on stormwater.
Clariant's existing stormwater permit became effective on June 1, 2003. The following
are the most notable changes since that date.
Changes in production:
A production area, Building 190, was shut down, decommissioned, and partly
demolished. This area was formerly used to manufacture a detergent additive.
The product was discontinued.
Production activities in our area known as Plant 2 were shut down and moved into
our area known as Plant 5. Plant 5 had been vacant for several years. After the
move, Plant 2 was demolished. There are no significant changes in products or
quantities; just a change in location. Stormwater from the vicinity of Plant 5
discharges to Outfall 006, whereas Plant 2 stormwater discharged to Outfall 001.
Changes in storage practices:
- Outside storage of chemical -containing totes and drums has been reduced by
about 10%. This was accomplished by improvements in inventory management,
and by clearing space inside our Warehouse. Several outside storage areas have
been eliminated.
Changes in stormwater control systems:
- A barricade of rip rap was put in place east of our Building 190 area, to intercept
gravel from being washed into stormwater Outfall 004.
- A gate was installed at Outfall 006 for emergency use to contain any spills that
might appear headed for that outfall. Also, emergency spill supplies were
permanently placed at the Outfall 006 location.
- Secondary containment was installed at a rail car loading and unloading station at
our Plant 1 area. The containment system drains into our on -site wastewater pre-
treatment plant (WWTP).
- Spill diversion curbing and road humps were constructed in selected locations on
the east side of our plant. (Specific locations include: near and to the south and
east of our wastewater lift station and Outfall 003 containment area; and in the

road southwest of our wastewater pretreatment facility). These enhance our
capability to manage certain spills that might potentially head towards Outfall 004
or Outfall 006.
- Floor drains in our production buildings were rebuilt and/or sealed off to prevent
the possibility of seepage from process sewer drains into stormwater systems.
- The stormwater containment area at Outfall 003 was provided with the installed
capability to pump stormwater into our wastewater lift station. This facilitates our
ability to send stormwater, if contaminated, into our WWTP instead of releasing it
through the outfall.
- Two cooling towers located at Plant 3 had their blowdown piping modified to
Allow the option of discharging blowdown water into our WWTP instead of
Outfall 001, if necessary (for example, due to contamination).
- Process wastewater and stormwater systems in the Plant 5 area were upgraded to
reduce the chance of crossover contamination or overflow. For example, a curb
was constructed between different types of sumps to separate containment areas.
Piping cross connections were physically disconnected to eliminate any
possibility of process wastewater for entering stormwater through shared piping.
High level alarms were installed on all wastewater and stormwater sumps in the
Plant 5 area.
