Narrative Description
Storage Practices
Materials are stored in bulk storage tanks and in a variety of portable container types.
a. Bulk Storage Tanks
Product, intermediate, and raw material storage tanks are located in diked tank
farms. There are six main tank farm areas: Plant 1, Plant 2, Plant 3, Plant 4, Plant
5, and Area 190. There are also two dedicated tank storage areas: one for
ethylene oxide (EO) and one for propylene oxide (PO). Also, there are four
petroleum -based fuel storage tanks located throughout the site; these are not in
diked areas but they are double -walled tanks.
b. Containers
Solid and liquid materials are stored in a variety of container types. The most
common are 275-gallon totes and 55-gallon drums. There are also other drum
sizes as well as several types of bags, supersacks, and buckets. Container storage
locations can be virtually anywhere on site, the most common being inside the
Warehouse, inside of or outside near any of the production buildings (Plant 1,
Plant 3, Plant 4, Plant 5), and outside along the site roadways. Materials in bags
or other containers that could be damaged by rain are not stored outside.
Hazardous wastes are stored separately in designated areas.
Loading and Unloading Activities
Materials are loaded into and/or unloaded from rail cars, tank trucks, and trailers.
There are four rail car loading/unloading areas: Plant 1, Area 190, Plant 4 CFA/SI, and
EO/PO. There are seven tank truck loading areas: Plant 1, Plant 2, Plant 3, Plant 4,
Plant 5, Plant 4 IPF, and Area 190. All of these areas utilize loading racks designed for
that purpose. Containers are loaded into trailers at Warehouse loading docks and Plant
5 loading docks.
3. Outdoor Process Areas
Revision 5 page 3 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
Process areas are mostly covered or inside of buildings. There is some process piping
outside that is connected to the storage tanks in the diked areas. Also there is some
transfer piping outside between different buildings. Some notable examples of outside
process piping are wastewater piping and transfer Iines from Plant 1 to Plant 4. Also,
the entire wastewater treatment plant (WWTP) is located outside.
4. Dust and Particulate Generating Processes
The SCI process in Plant 3 generates a solid flake product. Several processes use
powders or solids as raw materials. All solid material handling is done inside the
process buildings: Plant 3, Plant 4, and Plant 5.
5. Waste Disposal Practices
The MHW Plant has well -established practices that assure the proper handling and
disposal of waste. The following is a brief description of how the most common waste
types are managed.
a. Trash
Generic non -hazardous trash is placed trashcans or small dumpsters, which are
collected daily. The trash is emptied daily, compacted, and placed into a roll -off
container. The roll -off container is removed weekly by a local waste company
and taken to a Clariant-approved Subtitle D landfill. This trash category includes
empty chemical bags, chemical gloves, non -regulated samples, non -regulated
filter pads, foodstuffs, non -recyclable office materials, and miscellaneous
household trash.
b. Chemicals
All chemical wastes are placed in compatible DOT containers. Only personnel
with proper training are authorized to handle chemical waste. The person who
generates a waste obtains the samples and information necessary to characterize
the waste. They then submit the waste, along with a completed Waste Inventory
Sheet (WIS), to the Waste Department. The Waste Department stores the waste
in a designated storage area. The Waste Department then determines the proper
classification and disposal method for the waste. Non -hazardous chemical waste
is typically disposed in a Clariant-approved Subtitle D landfill. Hazardous waste,
and some non -hazardous waste, is sent to a Clariant-approved permitted TSDF.
All chemical waste is tracked by manifest.
C. Recyclable Materials
Various types of containers are staged throughout the MHW site for the
collection of recyclable materials. These materials include paper, cardboard,
wood, and scrap metal. Scrap metal is cleaned prior to recycling and evaluated
by the Waste Department to ensure that it meets the definition of scrap metal and
is managed properly.
d. Universal Waste
Revision 5 page 4 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
Universal wastes such as bulbs, batteries, and mercury -containing devices are
collected as they are generated, secured in appropriate containers, and stored in a
designated area. Universal wastes are periodically picked up and taken to a
Clariant-approved facility.
e. Soil
The MHW Plant has an excavation permit process that ensures that all excavated
soil is properly evaluated, managed, and disposed. The Waste Department
determines the classification of the soil and the appropriate disposal options. If
necessary, soil samples are sent to a certified lab for analysis. if a designated
Solid Waste Management Unit (SWMU) is involved, proper documentation is
developed. Any soil that is determined to be hazardous waste is sent to a
Clariant-approved Subtitle C landfill or other TSDF, as appropriate.
f. Wastewater Residuals
Sludge from the WWTP is collected in a sludge storage building. Approximately
every two weeks, it is Hauled off and land applied according to the site's Land
Application permit. Sometimes if there is no permitted field available the sludge
is disposed in a Clariant-approved Subtitle D landfill-
C. Site Map
Attachment 2 is a map of the industrial areas of the MHW site. All items required to be in the
site map are either shown in Attachment 2 or are described below in this section.
Storage of Materials
Bulk tank storage locations are shown on the site map. Outside areas most commonly
used for storage of materials in containers are also shown on the site map. Inside
storage areas are not specifically indicated, other than designated hazardous waste
storage areas. Inside storage is mainly in the Warehouse.
2. Disposal Areas
There are no disposal areas on site. All wastes are accumulated, stored, and sent off
site for disposal.
3. Process Areas
Process areas are indicated on the site map. The main areas are: Plant 1 (Building 151),
Plant 3 (Building 153), Plant 4 (Building 154), Plant 5 (Building 155), Pilot Plant
(Building 159), and WWTP (Area 163).
4. Loading and Unloading_ Areas
Loading and unloading areas are shown on the site map.
Drainage Structures
Revision 5 page 5 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
The MHW Plant has a network of stormwater sewers and industrial sewers. The
sewers are generally separate systems, although there are locations where stormwater
can be transferred into the industrial sewers. The stormwater system includes not only
sewers but also sumps, curbs, containment walls, a retention pond, and outfall valves.
All of these structures are shown on the site map.
6. Draina a Areas for Each Outfall
The approximate drainage areas for each outfall are indicated on the site map. Note
that Outfall 006 receives a substantial portion of its drainage from public streets and
neighborhoods; these off -site sources of drainage are not on the site map.
Activities Occurring in Each Drainage Area
Activities throughout the M14W Plant have already been described and are indicated on
the site map.
Buildiniz Locations
Building locations are shown on the site map.
9. Existing BMPs
Some of the more significant Best Management Practices (BMPs) are as follows:
a. Secondary containment is provided for the bulk storage of chemicals.
b. Loading and unloading operations are conducted in paved areas that drain into
the industrial sewer.
C. Secondary containment is provided around the truck scale.
d. Process areas utilize written procedures for all chemical -handling tasks.
e. Containment curbing is provided for most of the site, to provide additional
protection for areas having the greatest risk of loss of containment.
£ Outfall valves and containment area valves are normally kept closed. Only
authorized employees open them after inspection of the stormwater.
g. Outfalls and containment structures are inspected regularly.
h. All employees who work in chemical process areas receive training in operating
procedures, spill prevention, and spill response.
i. The site has an emergency response team (EAT) on site, trained in spill
containment and mitigation.
j. Major construction contractors are required to have an erosion control plan.
k. 5S program has been implemented to clean and organize work areas.
10. Impervious Surfaces
Most of the active portion of the site has impervious surfaces. All chemical storage,
handling, loading, and unloading activities are in impervious areas, except the
following areas are gravel: Area 190, Plant 4 CFA/SI, and EO/PO rail car loading
areas; the storage area for roll -off containers of non -hazardous waste drums; and the
WWTP.
Revision 5 page 6 of 15 January 30, 2009

Drainage Area Surfaces
The percentage of each drainage area that is impervious can be determined from the
following estimates:
a. Outfall 001
b. Outfall 003
C. Outfall 004
d. Outfall 005
e. Outfall 006
f. Outfall 007
� h1l)
Note that (i) the Outfall 006 estimates include only the on -site drainage areas but not
the public drainage areas and (ii) the Outfall 007 estimate is based only on the truck
dike that drains into it.
Potential Pollutants
Permeable area: 146,800 ft2
Permeable area: 83,700 ft2
Permeable area: 91,200 ft2
Permeable area: 45,000 ft2
Permeable area: 176,400 ft2
Permeable area: 0 ft2

Impervious area: 43,800ft2
Impervious area: 5,700ft2
Impervious area: 327,700ft2
Impervious area: 1,400ft
Normally, no pollutants are discharged through any of the MHW Plant's stormwatcr
outfalls. The potential pollutants described in this section could be present only in the
event of an unplanned release that enters the stormwater sewer system.
a. Outfall 001
Most of the chemical process areas on site are within the stormwater drainage
area for this outfall. There are more than 400 chemical raw materials and
products on site, and virtually all of them could potentially enter Outfall 001.
Some of the major categories include: fuels, heat transfer fluids, fatty alcohols,
fatty acids, alkylphenols, EO & PO, caustic, acids, amines, resins, phenols,
xylene, formaldehyde, DEET, and biocides. Detailed lists are available in the
site's annual Tier 2 report or in the chemical inventories for each building.
b. Outfall 003
Drainage to this outfall is mainly from Area 190, Plant 1, and the roads south and
east of the Warehouse. There is also the possibility of receiving overflow from
the Outfall 001 drainage area or from the industrial sewer system. Because
virtually any chemical on site could find its way to Outfall 003 from at least one
of these source areas, the list of potential pollutants is the same as for Outfall
001.
C. Outfall 004
This outfall receives overflow from the Outfall 003 drainage area, the Outfall 005
drainage area, and some on -site roads. While there are some chemicals unlikely
to flow all of the way to Outfall 004 (e.g. EO & PO), the chemical transport
vehicle traffic on the on -site roads and the proximity several loading areas makes
it possible for the most of the chemicals described for Outfall 001 to be
considered potential pollutants at Outfall 004. Also, gravel can potentially wash
down from any of several sloped areas into Outfall 004.
Revision 5 page 7 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
d. Outfall 005
The WWTP is the main activity within the drainage area for this outfall.
Potential pollutants from the WWTP include treated wastewater, wastewater
residuals (sludge), liquid polymers, defoamers, phosphoric acid, and urea.
Occasionally some non -hazardous waste is stored near the trash compactor,
which is also located in the Outfall 005 drainage area.
Outfall 006
The drainage area for this outfall includes Plant 5 and the road west of the
WWTP. There are potentially more than 100 chemical raw materials and
products in the Plant 5 area, and virtually all of them could potentially enter
Outfall 006. Some of the major categories include: fatty alcohols, fatty acids,
alkylphenols, caustic, acids, amines, resins, phenols, xylene, and formaldehyde.
Detailed lists will be available in the site's annual Tier 2 report or in the chemical
inventory for Plant 5. Wastewater from the WWTP is another possible pollutant.
Outfall 006 also receives all stormwater flow from Outfall 007. And also,
Outfall 006 receives a large volume a stormwater from the public stormwater
system. Clariant has no knowledge of potential pollutants from sources outside
of its control.
f. Outfall 007
Outfall 007 receives stormwater from the back parking lot, the lawn beside the
Administration Building, the roads around the parking lot, and the truck scale.
The main potential for pollutants comes from the truck scale. Most chemicals on
site are weighed on the scale at some point, so again, with some exceptions, most
of the potential Outfall 001 pollutants are also potential Outfall 007 pollutants.
D. Sinificant Spills
There have been two significant releases to the Catawba River within the past three years.
1. The first occurred on August 21, 2007, when a rupture disk operated in Plant 3,
releasing the contents of a reactor. The reactor contained a mixture of raw materials
used for manufacturing a soap ingredient, Hostapon SCI 65. Approximately 10,000 lbs
were released, with an estimated 500 lbs landing in the river. The raw materials in the
reactor were coca hydrogenated fatty acid (550/6), Hostapon SI 57% (450/0), and zinc
oxide (0.03%). A film of this material developed on top of the river. The incident was
reported to the National Response Center and several local agencies, and the material
was cleaned out of the river within 24 hours. Note that this incident did not actually
involve the site's stormwater system, although it did cause materials to enter the river.
The site's containment systems functioned effectively to prevent any materials landing
on the site property from entering the river through stormwater. The incident report
can be found in Clariant's Incident Management System (IMS) in the Lotus Notes
database, report number 20070045.
2. The second release was discovered on June 3, 2008. A Plant 5 chemical sump pump
malfunctioned and overflowed into the storm sewer during a rain event. The storm
Revision 5 page 8 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
sewer leads to Outfall 006. Residue samples taken from the storm sewers and the
outfall showed evidence of sodium hydroxide and n,n-dimethyl alkyl (C12-C1 S)
amines. These are both production materials that were used in Plant 5 prior to the _
incident discovery. A working committee was convened and as a result there have d
been numerous improvements made to the Plant 5 sewer system. Another incident
identical to the one that occurred is no longer a feasible event. The committee remains
active, with several more stormwater system improvements planned.
Reports of minor spills can also be found in IMS.
U. STORMWATER MANAGEMENT PLAN
A. Feasibility Study
1. Storage Areas
a. Bulk Storage
There is no identified need to change methods of operation to reduce exposure of
bulls storage tanks to stormwater. Although product and raw material storage
tanks are exposed to stormwater, they are all located within secondary
containment. Fuel tanks are not located in secondary containment but they are
double -walled tanks that are inspected regularly.
b. Container Storage
Some chemical containers are stored inside the Warehouse where they are not
exposed to stormwater. However, many chemical containers are stored outside
where they are exposed to stormwater. Except for Plant 5, stormwater runoff
from container storage areas is controlled procedurally through the use of the
outfall valves. In the event of a release from a container, all applicable outfall
valves will be closed and the stormwater will be contained and/or diverted to the
industrial sewer. (The stormwater valves are normally kept closed most of the
time). Plant 5, instead of relying on outfall valves, is set up so that containers are
only stored in locations that drain to the chemical sewer, which does not
discharge to any outfall. Sitewide efforts in 2006 and 2007 successfully
eliminated several outside container storage areas. Further improvements have
been identified to provide covers and/or containment for several remaining
outside container storage areas. In particular, a large contained storage area is
eventually planned for the former Plant 2 location.
2. Material Handling erations
All loading (and unloading) areas are exposed to stormwater. These loading areas have
a variety of secondary containment provisions, ranging from some areas that have the
capability of containing a full tanker load of material, to other areas that do not have
secondary containment at all. Stormwater runoff from loading areas is controlled
procedurally through the use of the outfall valves. All loading activities are attended.
In the event of a release during loading activities, all applicable outfall valves will be
closed and the stormwater will be contained and/or diverted to the industrial sewer.
(The stormwater valves are normally kept closed most of the time). The feasibility of
Revision 5 page 9 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
providing additional protection by constructing full secondary containment for all of
the loading areas will continue to be evaluated. One notable improvement planned for
2009 is the installation of an automated pump to pump out the Plant 4 tanker loading
sump into the contained Plant 4 tank farm dike area.
Manufacturing Operations
There is no identified need to change methods of operation to reduce exposure of
manufacturing processes to stormwater. Virtually all process operations take place
either inside buildings or within contained areas.
4. Fueling Operations
The only fueling operations occur at the gasoline tank, where a few gasoline -fueled
vehicles are fueled. Fueling occurs relatively infrequently. The fueling area is exposed
to stormwater and it does not have secondary containment. Stormwater runoff is
controlled procedurally by ensuring that the Outfa11001 valve is closed while fueling.
The feasibility of providing additional protection by constructing secondary
containment or relocating the gasoline tank is being evaluated.
B. Secondary Containment Schedule
1. Bulk Storage of Liquid_ Materials
Bulk storage areas already have adequate secondary containment. Containment areas
are either pumped to the industrial sewer or drained to the stormwater sewer. Drainage
to the stormwater sewer is controlled by manual valves that are normally kept closed.
Only W WTP employees are authorized to open these valves and release accumulated
stormwater. Before releasing any stormwater, WWTP personnel visually observe the
water for color, foam, staining, sheens, and evidence of dry weather flow. Records of
each inspection and stormwater release are documented and kept in the WWTP. There
is a written WWTP procedure detailing the steps described here.
2. Storage of SARA 313 Water Priority Chemicals
The following SARA 313 water priority chemicals are stored on site: benzyl chloride,
formaldehyde, hydrochloric acid, maleic anhydride, naphthalene, phosphoric acid,
propylene oxide, sulfuric acid, and toluene. Chemicals stored in bulk are within
secondary containment areas. Chemicals stored in containers are generally stored in
the Warehouse but could be stored in any inside or outside storage area. Inside storage
areas, including the Warehouse, have adequate secondary containment. Outside
storage areas do not have local secondary containment. Secondary containment is
provided by the outfall valves as described earlier, and also by the Plant 5 layout as
described earlier. A schedule for providing local secondary containment for additional
protection will be developed.
3. Hazardous Substances
Bulk storage areas already have secondary containment as described above. Containers
of hazardous substances could be stored in any inside or outside storage area. Inside
storage areas have adequate secondary containment. Outside storage areas do not have
Revision 5 page 10 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
local secondary containment. Secondary containment is provided only by the outfall
valves as described earlier, and also by the Plant 5 layout as described earlier. A
schedule for providing local secondary containment for additional protection will be
developed.
C. BMP Summary
The MHW Plant currently uses numerous BMPs to prevent and/or minimize the potential for
pollutants to reach surface waters. These BMPs have been developed and implemented based
on many years of experience, and have taken into consideration the types, volumes, and
locations of potential pollutant sources. A long history of stormwater monitoring data has
affirmed the effectiveness of these BMPs.
l . 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.
3. Secondary containment is provided around the truck scale.
4. Process areas utilize written procedures for all chemical -handling tasks.
5. Containment curbing is provided for most of the site, to provide additional protection
for areas having the greatest risk of loss of containment.
6. Outfall valves and containment area valves are normally kept closed. Only authorized
employees open them after inspection of the stormwater.
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, trained in spill containment
and mitigation.
10. Major construction contractors are required to have an erosion control plan.
II1. SPILL PREVENTION AND RESPONSE PLAN
A. Assessment of Potential Pollution Sources
Potential pollution sources are described in detail in the Sections I and II of this Stormwater
Pollution Prevention Plan (SPPP)_ All areas of chemical operations, loading, and storage are
potential pollution sources. All chemicals handled on site are potential pollutants. In relative
terms, the most significant potential sources are those that do not have complete secondary
containment in the immediate vicinity. These areas include process sewers, certain loading
areas, and certain outside chemical container storage areas.
B. Responsible Personnel
Spill prevention and response is the responsibility of all employees working inside the plant.
Some specific responsibilities are detailed within the following two sections of this SPPP.
C. SPW Prevention
Spill prevention is accomplished by the use of standard operating procedures. All employees
who handle chemicals are responsible for following established procedures. Spill prevention
is also effected by properly maintaining equipment in good working condition. Area owning
Revision 5 page 11 of 15 January 30, 2009
Stormwater Pollution Prevention Plan
departments and Maintenance are jointly responsible for ensuring the mechanical integrity of
equipment designed to containment chemicals or prevent spills.
D. Spill Control
Many spills can be controlled without a major "response" effort if proper procedures are
followed to utilize the site's secondary containment facilities_ Employees who handle
chemicals are primarily responsible for ensuring proper use of such facilities in the event of a
spill. Waste Department personnel also have a role in managing certain spill containment
areas. Area supervision is responsible for ensuring the adequacy of the procedures and
containment in their areas.
D. Spill Response
Spill response procedures, equipment, training, and responsibilities are described in detail in
the site's Emergency Response Plan (ERP) and Spill Prevention Control and
Countermeasures (SPCC) Plan. These plans are not duplicated within this SPPP, but they are
incorporated by reference. Both referenced plans describe in detail the responsibilities for
initial response, small spill response, and major spill response.
IV. PREVENTIVE MAINTENANCE AND GOOD HOUSEKEEPING
A. Stormwater System IIISpecWQns
System Inspections
All stormwater systems are formally inspected twice per year. These inspections are
documented using a checklist. These inspections provide a means of systematically
assessing the condition of stormwater facilities. Completed checklists are filed in the
Waste Department.
2. Daily Inspections
WWTP operators visually inspect all stormwater outfalls and stormwater containment
areas at least once per shift. These inspections are intended to identify any obvious or
critical problems.
Correction of Deficiencies
If a deficiency is noted during an inspection, the owning department is notified and
becomes responsible for ensuring that the necessary repairs are completed. The
Environmental Team Leader is responsible for any revisions to this SPPP. Resolution
of corrected deficiencies will be noted on a subsequent inspection checklist.
B. Process Equipment Inspections
Mechanical Integrity Inspections
In accordance with the site's preventive maintenance and mechanical integrity
programs, each production area works with Maintenance to assure that all critical

C. Maintaining clean conditions around trash dumpsters.
d. Ensuring that dust and powder levels near building vents are kept to a minimum.
e. Proper labeling of all containers.
f. Prompt cleanup of spills.
g. Maintaining adequate aisle space.
h. Storing containers out of the path of common traffic routes.
i. 5S program has been implemented to clean and organize work areas.
2. Monthly Inspections
Monthly safety and housekeeping inspections are conducted by each department.
These inspections are documented on a checklist. Each department is responsible for
correcting deficiencies identified by these inspections.
V. EMPLOYEE TRAINING
A. Training Schedule
All employees whose jobs have the potential to affect stormwater are trained at least once per
calendar year.
B. Training Content
Annual training includes: proper spill response and cleanup procedures, housekeeping
practices, maintenance and inspection requirements, spill containment facilities and
procedures, and a review of the stormwater sewers and stormwater outfalls at the site.
Additional topics of emphasis are often added each year.
