PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Perrnittee 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
stormwater discharges. The site plan shall contain the,following:
(a) A general location map (USGS quadrangle,map or appropriately drafted
equivalent map), showing the facilitys'location in relation to transportation routes
and surface waters, the name of the--receivi g.ater(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 points) of discharge. The general location
map (or alternativelythe•site`map) shall identify whether each receiving water is
impaired (on the state''s,303(0)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 des`` ption 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 stormwater 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.
(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 11I, Standard Conditions, Section

Permit No. NCS000030
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
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 stormwater, 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 permittee shall
prevent exposure of all storage areas, material"handling operations, and
manufacturing or fueling operations. In area's. where elimination of exposure is
not practical, the stormwater management plan shall -document the feasibility of
diverting the stormwater runoff away fro areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of ligdid 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 stormwater runoff. A table
nks wand stored materials and their associated secondary
or summary of all such,-ta
containment areas shall;be,mi-intained. 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 4ocking: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 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.
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 II Page 2 of 10

Permit No. NCS000030
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, 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,
material handling areas, disposal areas, process areasploa'ding and unloading areas, and
haul roads), all drainage features and structures; and�existing structural BMPs. The
program shall establish schedules of inspections, maintenance;rand housekeeping
activities of stormwater control systems, as welh as facility equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater 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 sha11'be recorded in writing and maintained
in the SPPP. Ot�f

5. Employee Training. Training programs, shall be developed and training provided at a
g .�� p� gr�p
minimum on an annual basis -far -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 stormwater 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 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. 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,

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 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.

This site discharges to impaired waters experiencing problems with ecolo0cal/biological
integrity and benthos (aquatic life). Additionally, a Total Maximum Daily Load (TMDL) is
approved for this segment of Little Troublesome Creek for pollutants including lead, cyanide,
cadmium, chromium, chlorine, fluoride, MBAS, and fecal colifonn. As such, the permittee may
be required to monitor for the pollutants of concern in the future and submit results to the
Division of Water Quality if it is determined that the permittee is a potential contributor of any of
the TDML pollutants to the impaired waterbody. The Division will consider the monitoring
results in determining whether additional BMPs are needed to control the pollutants of concern to
the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the permitted Stormwafe;,Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection ofeach'stormwater outfall regardless of
representative outfall status and shall be performed as.specif ed in Table 4, during the analytical
monitoring event. [If analytical monitoring is not,required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualita ivefmonito i g is for the purpose of evaluating the
effectiveness of the StormwaterTollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.
In the event an atypical condition is noted.a't a stormwater discharge outfall, the permittee shall
document the suspected cause/'of the condition and any actions taken in response to the
discovery. This documentatio n-will'b'e maintained with the SPPP.

2. All analytical monitoring has been set to semi-annual 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. .
3. A tiered response system 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.
4. All analytical and qualitative monitoring samples must be collected during representative storm events
as defined in Part II Section B.
5. The permittee is responsible for all monitoring until the renewal permit is issued.
6. Vehicle maintenance monitoring has been revised to semi-annually and requires the collection of Non -
polar oil & grease I TPH with a revised benchmark value of 15 mg/L. This requirement appears in all
Individual Stormwater permits; however it only applies to facilities that perform vehicle maintenance.
7. An annual DMR.summary is due to the Winston-Salem Regional Office by•March 1 of each year.
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.

NCS000167
Revised Permit Recommendations: Analytical Monitoring:
1. Proposed strategy: Frequency to remain -at semi-annual. Modifying parameters as follows:
a. Removing parameters:
i. COD — tiio benchmark e�ceedances. Previous permit allowed tol' discolltintlatlon of COD
monitoring so COD will be formally removed from monitoring requirements.
b. Maintaininparameters:
i. TN"— TKN was mistakenly monitored instead of'TN so this parameter cannot be removed
xvithout further data. Nutrients are problematic for receiving water and watershed in general.
Liquid nitrogen produced onsite - potential source.
c. AddinY� parameters:
i. pH — standard addition plus one hcrichmark esceedance observed with vehicle maintenance
monitoring.
2. The Tiered monitoring system has been added to this draft permit.
3. Analytical and qualitative monitoring required during representative storm events. Qualitative monitoring
required regardless of representative outfall status. Qualitative monitoring to be performed semi-annually.
4. Annual summary DMR will be due to RO in March of every year
5. Updated vehicle maintenance monitoring to reflect change in TPH nomenclature to Non -Polar Oil and Grease
[EPA Method 1664 (SG-l'-HPM)].
Other Proposed Changes to the Previous Permit:
1. See draft permit for full details.
Discussion with Permittee: Joseph Sebia, Facility Contact, May 10, 2010, sebiaj u,airproducts.com
Please provide an owner contact name for this facility.
o See email correspondence in tile.
Why was TKN monitored (according to the analytical summary) when TN was specified in the permit?
o This resulted from a miscommunication between the Iacility and laboratory and was not corrected
until now.

Dear Permittee:
Dee Freeman
Secretary
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000030. This permit expires on
September 30, 2010. To assure consideration for continued coverage under your individual permit, you must apply to
the Division of Water Quality (DWQ) for renewal of your permit. Enclosed you will find an individual permit Renewal
Application Form, Supplemental Information request, and Stormwater Pollution Prevention Plan Certification for your
facility.
Filing the application form along with the requested supplemental information will constitute your application for
renewal of this permit. Until your permit renewal is completed and you receive a new permit, please continue to
comply with all conditions and monitoring requirements in your expired NPDES stormwater permit.
The application and supplement must be completed and returned to DWQ by May 1, 2010. Failure to request renewal
within this time period will result in delay of your permit renewal and may result in a civil assessment. Discharge of
stormwater from your facility without coverage under a valid Stormwater NPDES permit would constitute a violation
of NCGS 143-215.1 and could result in assessments of civil penalties of up to S25,000 per day.
If you have any questions regarding permit renewal procedures please contact Brian Lowther of the Stormwater
Permitting Unit at (919)-807-6368 or [e-mail].

8. MEASURES AND CONTROLS
The most effective method to prevent pollution of surface water or ground water is to implement
Best Management Practices (BMPs). BMPs are measures or practices used to reduce the
amount of pollution entering surface water, air, land or ground water. BMPs may take the form of
a process, activity or physical structure. There are three types of BMPs implemented at APCI
industrial gas facilities:
• Baseline BMPs
• Advanced Generic BMPs
• Advanced Site -Specific BMPs
If a particular advanced BMP is implemented at this facility, the location where it is implemented
is identified in Worksheet B2. For example, if the BMP described in Section 8.2.1 is implemented
at a bulk storage container, the entry for the storage container in Worksheet B2 will identify "BMP
8.2.1 - Secondary Containment" in the BMP column of the worksheet. Any other applicable
advanced BMPs should also be identified in Worksheet B2. Baseline BMPs will not be identified
in Worksheet B2 since they generally apply to the entire facility and not necessarily to a specific
source.
8.1 BASELINE BEST MANAGEMENT PRACTICES
Baseline BMPs are general practices that apply to most industrial sites, independent of the types
of materials used, processes employed, products manufactured, or site location. Baseline BMPs
are relatively simple, inexpensive, and cost-effective because they emphasize prevention of
pollution rather than treatment of pollutants. The baseline BMPs listed in Section 8.1 are
employed across the entire facility and are not necessarily associated with any specific source of
significant materials listed in Worksheet B2 of Appendix B.
8.1.1 GOOD HOUSEKEEPING
Good housekeeping involves a common sense approach to improve and maintain a clean and
orderly work environment by implementing the following practices:
• Sweeping parking lots
• Storing chemicals in a neat and orderly manner
• Clean up discharges promptly
• Regular refuse pickup and disposal
• Good storage and material inventory practices, including labeling of all containers
• Schedule routine cleanup efforts
• Discuss and promote good housekeeping practices with employees
mull asXL4i1tGIVL41fllk1k941V1, [qQ
A preventive maintenance program is an effective BMP for preventing surface water or ground
water pollution. A preventive maintenance program should include:
• Timely inspection and maintenance of storm water management devices (e.g., cleaning
oil/water separators, catch basins, etc.)
• Inspection and testing of facility equipment and systems to uncover conditions that could
cause breakdowns or failures resulting in discharges of pollutants to surface water and

Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
ground water (including pipes, pumps, storage containers and bins, pressure vessels,
pressure release valves, and process and material handling equipment)
• Proper maintenance of facility equipment and systems
8.1.3 RELEASE RESPONSE AND REPORTING PROCEDURES
Effective discharge and release response and reporting procedures are important because they
provide for rapid response to mitigate the impact of the release. Release response and reporting
procedures for this facility are described in more detail in Section 9. These procedures describe
the following measures that will be implemented upon discovery of a significant release:
• Access the risk
• Control the release to the extent possible
• Report the release to management and government agencies
• Clean up the impacted area as soon as possible
• Follow up with preventive measures '
8.1.4 INSPECTIONS
This facility is required to conduct a formal, documented inspection on a semiannual basis during
the spring (April -June) and the fall (September -November) using a copy of Worksheet B2.
Inspection criteria are listed in the instructions to Worksheet B2.
In addition to documented inspections, regular observations of process and material storage
areas are encouraged to ensure that discharges are detected and responded to as in a timely
manner. Observations can be conducted during employees' regular "rounds" of the facility
grounds and need not be formally documented.
8.1.5 OIL HANDLING PERSONNEL TRAINING
Pollution prevention training for oil handling personnel must be held at least annually. Training
must be documented in the facility's training database or in employee records located at the
facility. Personnel are trained in the following areas, with drivers receiving awareness training:
• Release Prevention, Reporting, and Response - a review of emergency procedures,
communications, and reporting and cleanup techniques.
• Pollution Prevention - a review of the purpose, goal, content, and regulatory requirements of
this Plan, potential sources of oil pollution at the site, BMPs implemented at the site, and the
role personnel fulfill in pollution prevention.
• General facility operations
• Operation and maintenance of equipment to prevent oil discharges
• Corporate EH&S Training Package -- entitled "Preventing Accidental Pollution of Surface
Waters"
• Discharge Briefings — a discussion of any known discharges or failures, malfunctioning
components, and any recently developed precautionary measures.

8.1.6 RECORDKEEPING AND INTERNAL REPORTING PROCEDURES
Good record keeping and reporting procedures help to identify and communicate information
about potential sources of surface water and ground water contamination and assure that
appropriate measures are taken. This Plan includes procedures for recording incidents, such as
spills or other discharges, along with other information describing the quality and quantity of
potential pollution sources. All pertinent information regarding a discharge will be documented
and records maintained for three years. Pollution prevention record keeping and reporting are
integrated into current management systems and include:
• The use of the Resource Management System (RMS) preventive maintenance system, or an
equivalent system, for scheduling applicable preventive maintenance tasks and inspections.
• Required reporting of discharges to Line Management, Field EH&S Specialist, and Corporate
EH&S.
• Recording of incidents via the APCI Incident Tracking System
• The periodic review of significant safety and environmental issues or incidents and corrective
action progress by a Line and Staff Management Safety Committee.
8.1.7 SPILL CLEANUP KITS AND MATERIALS
Spill cleanup kits are maintained at the facility. They are routinely inspected to keep them in good
working order. These kits are composed of absorbent sheets, pillows and booms, as appropriate.
In addition, sorbent materials such as oil-dri or vermiculite should be available at all times.
Alkaline neutralizing kits or materials such as soda ash or lime should also be available onsite
from a nearby chemical distributor, for those facilities that use sulfuric acid for cooling water
treatment. Spill cleanup kits or materials are typically maintained within a reasonable distance of
the following areas:
• Truck fueling area and tractor staging/parking
• Truck terminal
• Air Separation Unit (ASU) compressor area/Air Separation Process
• Maintenance buildings and storage areas
• A dedicated spill kit on each truck tractor
• Process equipment with liquid materials in service
• Material loading and unloading areas
8.1.8 EMERGENCY RESPONSE CONTRACTORS
In the event of a discharge, outside assistance for cleanup may be required. Worksheet B4 in
Appendix B lists emergency response contractors located within a reasonable response time from
this facility. The primary emergency response contractor has provided information regarding
qualifications (availability of the necessary personnel and equipment within appropriate response
time). Worksheet B10 in Appendix B has been completed by the response contractor and has
been inserted in the Plan.
8.1.9 EMERGENCY PREPAREDNESS AND COMMUNICATIONS
This facility shall have a Site Emergency Plan prepared in accordance with the Gases and
Equipment Group (GEG) EH&S Procedure 01.08.02, "Site Emergency Planning". Additionally,
GEG EH&S Procedures 01.08.05.A.M., "Crisis Management" and 01.08.16.A.M., "HAZWOPER"

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
address emergency preparedness. These procedures can be found in the GEG Worldwide
Operations and Distribution Manual.
8.1.10 SECURITY
This facility is completed surrounded by a security fence. Access to the site is controlled through
a main gate. Entry through this gate can be made only by a security access code or through
permission received from the Control Room. Storage containers, secondary containment
systems, process areas and piping systems are confined within the fence line. The area is
lighted and is subject to typical facility security measures, including restricted vehicular traffic.
8.2 ADVANCED GENERIC BEST MANAGEMENT PRACTICES
Advanced generic BMPs are generic measures or practices that are employed to address specific
sources, materials, or activities that may be present at the facility. They include generic
prevention, containment, and mitigation practices that can be applied to specific sources (e.g.,
fueling stations) commonly found at APCI industrial gas facilities. Section 82 provides a
reference list of generic BMPs that may be used at industrial gas facilities. Those source -specific
BMPs that are actually implemented at this facility, and the locations where they are
implemented, are listed in Worksheet B2 of Appendix B.
8.2.1 SECONDARY CONTAINMENT
Secondary containment systems are effective in controlling discharges. To be most effective,
secondary containment systems and diversionary structures should meet the following standards.
• The systems block possible routes by which discharged materials could reasonably be
expected to flow, migrate, or escape into surface waters or upon the land from within the
containment areas. Manually operated valves are normally in a closed position and locked.
• The secondary containment systems have sufficient capacity to contain the largest probable
discharge that could occur in the containment area plus an additional capacity to compensate
for anticipated normal accumulation of rainwater.
• The secondary containment system is sufficiently impermeable to contain discharged
material for a duration necessary for the cleanup or recovery of the discharged substance.
• The secondary containment system is routinely inspected for accumulated liquids, debris, or
incompatible materials.
• No transfer area, curbed storage area, or secondary containment system is drained into a
watercourse or public sewage treatment plant unless provision is made to retain, by secured
valves or other means, any accumulated rainwater until its condition can be determined.
Adequate records are to be kept for discharges of uncontaminated rainwater.
• No incompatible materials are stored within the same containment area.
8.2.2 LOADING AND UNLOADING OPERATIONS
The following measures are key to preventing the release of significant materials during transfer
operations:
Rev.:3, Date: 03/16/2010 17

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
Training - Prevention of the release of materials during transfer operation is accomplished
through implementing procedures discussed during personnel training programs, regular
safety meetings, and briefings.
• Vehicle positioning - Whenever possible, vehicles should be positioned within spill
containment areas during transfer. Positioning near or over storm drains or sewer drains
should be avoided. Wheel blocks and emergency brakes should be used to avoid sudden
movement of the vehicle. If the vehicle is positioned near a traffic corridor, traffic barriers
should be placed to avoid collisions.
• Pre -positioning of spill kits, booms, or sewer block mats - If secondary containment is not
available during loading or unloading, spill kits must be readily available and spill mats or
booms should be pre -positioned to seal any nearby catch basins that could lead directly to
surface water or sewer systems. The discharge diversionary measure should be capable of
containing the maximum capacity of a single compartment of the vehicle being loaded or
unloaded.
• Pre -inspection of connections, fittings, and hoses - Prior to each transfer operation,
connections, hoses, gaskets and fittings must be checked to ensure they are in good working
condition. Loading and unloading areas must be well illuminated if material transfer occurs at
night.
Drip pans - Drip pans or buckets must be used to catch small volume leakage from transfer
hoses or fittings during transfer operations. Captured materials should be reused or properly
disposed.
• Overfill prevention - During a delivery, tank truck operators must be instructed to remain with
the vehicle along with at least one qualified facility employee. Before a delivery, the liquid
level in the receiving container is checked. Employee training procedures include instructing
operators not to leave the delivery area prior to checking and disconnecting the transfer line.
Prior to material transfer, qualified facility personnel and the driver are instructed to:
♦ Predetermine the maximum volume of material that can be transferred without overfilling
the container.
♦ Check the liquid level in the container(s) during transfer to avoid overfilling the container.
• Prior to departure — Qualified personnel and the driver are instructed to:
♦ Inspect the area for any sign of discharge. Control, report and clean up discharges
immediately.
♦ Ensure that all outlets from both the delivery vehicle and container have been tightened,
adjusted, or replaced to prevent a discharge.
8.2.3 ABOVEGROUND BULK STORAGE CONTAINERS
The following practices should be implemented for aboveground bulk storage containers
(specifically aboveground tanks):
• All pipes leading to and from aboveground bulk storage container(s) that enter the
container(s) below liquid level are equipped with valves sufficiently close to the container so
as to prevent the contents of a container from escaping the confines of the secondary
containment area in the event of a pipe rupture outside of the containment area. Any valves
Rev.:3, Date: 03/16/2010 18

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
that permit the direct outward flow of container contents are kept in the closed position when
in non -operating or standby status.
• In heavy traffic areas, protective guards or bollards should be placed around tanks and piping
to prevent vehicle or forklift damage. Piping runs are above standard truck height and behind
barriers.
• Containers, associated valves and piping should be clearly labeled to reduce human error.
• Containers are compatible with the material stored and the conditions of storage.
• Containers, associated piping, supports, and foundations must be routinely inspected for
integrity. Integrity testing is any means to measure the strength of the container shell and
may include leak testing to determine whether the container will discharge oil. Visual testing
in conjunction with another method of testing is required. Monthly visual inspections alone
might suffice in accordance with the deviation provision in section 112.7(a)(2), subject to
good engineering practice if :
0 Internal corrosion poses minimal risk
0 Visual inspections conducted at least monthly
0 All sides are visible, and
0 Containers have no contact with the ground
• Containers in contact with the ground must be evaluated for integrity in accordance with
industry standards and good engineering practice.
8.2.4 . FUELING STATIONS
The following practices should be implemented at fueling stations:
• Avoid toppin off - To minimize overfilling of truck fuel tanks, special fill procedures must be
followed to ensure that there is adequate room for expansion of cooler diesel fuel drawn from
underground tanks when it is placed in the truck saddle tanks and cryogenic delivery pump
engines. Hot summer weather greatly increases the potential for overflow of vehicle fuel
tanks that have been overfilled. To avoid this condition, the fuel tank should not be filled
above the neck on the fuel tank.
• Avoid unattended filling - When refueling vehicles, the driver must hold the fuel nozzle in
hand during the entire refueling operation, even if the fuel nozzle has an automatic shutoff
device.
• Avoid hosing down - Cleaning the fueling area with running water should be avoided because
the wash water will pick up fuel, oil and grease. Use dry clean-up methods whenever
possible. Control and clean up petroleum discharges immediately.
• Keep spill kits accessible - An adequate supply of spill kit materials should be available
before fueling vehicle. Control, report and clean up petroleum discharges immediately.
• Minimize storm water run-on - Minimize storm water run-on to the fueling area through flow
diversion around the fueling station and using roofs over the fueling area when feasible.

8.2.5 VEHICLE MAINTENANCE AND REPAIR
Many vehicle and equipment maintenance operations use materials that can be harmful to the
environment. The following practices should be followed at vehicle and equipment maintenance
operations to reduce or eliminate potential sources of pollution:
• Parts washing - Clean without using liquids (e.g., scraper, wire brush) whenever possible. Do
all liquid cleaning at a centralized station so solvents and residues stay in one area.
• Use nontoxic or low toxicity solvents - Minimize the number and volume of hazardous
materials used. Avoid chlorinated solvents. Choose cleaning agents that can be recycled.
• Control discharges - Collect leaking fluids in drip pans. Keep a drip pan under the vehicle
while unclipping hoses, unscrewing filters, or removing parts. Control discharges from
wrecked or damaged equipment that may be stored outdoors. Promptly transfer used fluids
to proper waste or recycling containers. Do not leave full drip pans lying around.
• Drain oil filters - Used oil filters disposed of in trash cans can leak oil and contaminate surface
water. Place used oil filters in a funnel over the waste oil recycling or disposal collection tank
to drain excess oil before disposal. Whenever possible, crush and recycle oil filters.
• Never pour liquid wastes into drains or onto the_ground - Do not pour liquid waste to floor
drains, sinks, outdoor storm drains, or sewer connections.
• Recycle materials - Whenever possible, recycle degreasers, used oil and oil filters,
antifreeze, cleaning solutions, automotive batteries, hydraulic fluid and tires.
• Searegate and label wastes - Separating wastes allows easier recycling and may reduce
treatment costs. Locate waste and recycling containers in clearly marked and controlled
areas.
8.2.6 VEHICLE AND EQUIPMENT WASHING
Washing vehicles and equipment outdoors or in areas where wash water can flow onto the
ground can pollute surface waters or ground waters. Wash water can contain high
concentrations of oil and grease, phosphates, and suspended solids. To reduce or eliminate
these potential sources of pollution:
• Use designated cleaning areas only. Wash water is regulated as a process waste water. It
can only be discharged to a properly permitted sanitary sewer or process sewer line.
• If a permitted sewer line is not available, wash water should be collected in bermed areas or
sumps for offsite disposal.
• As an alternative, offsite commercial washing facilities can be used.
8.2.7 WASTE MANAGEMENT AREAS
Wastes discharged, leaked or lost from waste management areas may build up in soils or be
carried away by rainfall. To reduce the potential for pollution, the following practices should be
implemented:
• Minimize the amount of waste managed on -site.
Rev.:3, Date: 03/16/2010 20

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
• Prevent run-off and run-on from contacting waste management areas.
• Keep waste containers closed or securely covered.
8.2.8 TRANSFORMERS
The following practices should be implemented in transformer yard areas:
• Transformers should be inspected periodically for evidence of discharges.
• Discharges must be cleaned up as soon as possible.
• Adequate spill kit materials should be available to prevent a discharge from reaching a
waterway.
8.2.9 OILIWATER SEPARATORS
The following practices should be implemented to assure proper operation of an oil/water
separator unit:
• The level of oil captured in the unit should be routinely monitored and removed by a properly
permitted used oil vendor.
• Any associated oil skimmers should be checked for proper operation.
• The waste water effluent from the unit should be routinely observed or monitored to
determine if the unit is functioning properly.
• The unit should be periodically cleaned to remove accumulated solids on the bottom of the
unit and on any coalescing plates.
• Discharges must be cleaned up as soon as possible.
• The discharge of solids and detergents to the oil/water separator should be minimized.
8.2.10 GREASE TRAPS AND GRIT CHAMBERS
The following practices should be implemented to assure proper operation of grease traps and
grit chambers:
• The levels of accumulated oil and solids should be routinely monitored and removed for
proper disposal.
• Any associated oil skimmers should be checked for proper operation.
• The waste water effluent from the unit should be routinely observed or monitored to
determine if the unit is functioning properly.
• Discharges must be cleaned up as soon as possible.
8.2.11 DRUMS AND BULK CONTAINER STORAGE AREAS
The following practices must be implemented at drum and bulk container ("drums") storage areas:
• The contents of all drums must be properly identified by a label.
Rev.:3, Date: 03/16/2010 21

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
• Drums that are stored in a horizontal position must be tightly sealed to avoid seepage
through the bung. Drip pans should be placed beneath horizontal drums that have a
dispensing valve installed.
• Drums should be kept closed except when material is being added or withdrawn.
• For drums stored outdoors, drums caps must be used to avoid accumulated rainwater on the
top lip of the drum causing contamination of the product. Outdoor drums must be stored off
of the ground to prevent bottom corrosion and possible leakage from the drum. Wooden
pallets may be used if an impervious surface is not available.
• Drums should be neatly stored with sufficient access and aisle space.
• Because empty drums often contain residual product, they must be managed according to
the practices listed above, unless they have been thoroughly cleaned.
• Leaking drums must be immediately moved to a containment area, placed in a salvage drum,
plugged, or the contents transferred into another drum. Discharged product must be cleaned
up immediately.
• Drums must be routinely inspected for integrity. Integrity testing is any means to measure the
strength of the container shell and may include leak testing to determine whether the
container will discharge oil. Visual testing in conjunction with another method of testing is
required. Monthly visual inspections alone might suffice in accordance with the deviation
provision in section 112.7(a)(2), subject to good engineering practice if:
0 Internal corrosion poses minimal risk
0 Visual inspections conducted at least monthly
0 All sides visible and/or drum storage area is located away from vehicular traffic, and
where discharges would be visible would not readily enter into a waterway conveyance
(i.e. surface water, sewer system)
0 Containers have no contact with the ground
• Containers in contact with the ground must be evaluated for integrity in accordance with
industry standards and good engineering practice.
8.2.12 SEDIMENT AND EROSION PREVENTION
The following practices should be implemented in areas of high soil erosion potential or during
construction periods:
• Preserve existing vegetation or revegetate disturbed soil areas.
• Stabilize stream banks.
• Install interceptor dikes and swales.
• Use fabric filter fences around disturbed areas.
• Maintain storm water retention/detention ponds in good operating condition.
8.2.13 SARA 313 WATER PRIORITY CHEMICALS
Facilities subject to reporting under SARA Section 313 for water priority chemicals may be
required to implement special BMPs for storm water pollution prevention. Any applicable, special
BM Ps are further described in Sections 10.5.2.through 10.5.7. They must be implemented in
areas where storm water can come in contact with SARA Section 313 water priority chemicals.

8.3 ADVANCED SITE SPECIFIC BEST MANAGEMENT PRACTICES
Advanced site -specific BMPs are measures or practices that are implemented at specific
locations at this facility. They include such BMPs for oil/water separators, bulk storage
containers, operating and electrical equipment, or underground storage tank leak detection
monitoring. Any deviations from the SPCC requirements will be documented, explaining the
nonconformance and providing equivalent environmental protection by some other means.
Examples may include measures for containment or diversionary structures and integrity testing.
Site -specific BMPs implemented at this facility are described in Section 8.3 and the locations
where they are implemented are identified in-Worksheet B2 of Appendix B.
8.3.1 TRUCK FUEL UNDERGROUND STORAGE TANK SYSTEM
The truck fuel underground storage tank system consists of two 10,000 gallon diesel fuel
underground storage tanks (USTs), submersible pumps with underground pressurized piping,
leak detection system, spill and overfill prevention devices, and an associated fuel dispensing
island. The tanks were installed in 1992.
The red jacket pump for the diesel oil system is equipped with an automatic line leak detector flow
restrictor that dramatically cuts the flow through the piping when the unit senses a leak. The
double walled fiberglass piping has an interstitial leak detection monitor in the form of a piping
sensor.
Tank Level Monitorino Svstem
The ATG is a Veeder-Root TLS-350 equipped with a continuous statistical leak detection (CSLD)
tank level monitoring system. The system includes a sensing probe in the tank and a remote
monitor with printer. The system provides continuous monitoring of product level, water level,
and product temperature. Whenever the fueling system is idle, the TLS-350 collects data and
performs a statistical analysis to detect leaks as small as 0.2 gallons per hour. There is no need
to shut down the fueling system for the leak detection test. Leak tests are constantly being
performed, and test results are automatically provided every 24-hour period, or on demand from
the console printer.
In addition to serving as a leak detection device, the Veeder-Root TLS-350 level monitor also
serves as a high level alarm. A red alarm light is remotely mounted at the fueling island to
indicate an overfill condition.
Shill Containment and Overfill Protection
To prevent surface spills and tank overfills, each tank is equipped with a catchment basin, overfill
alarm, and automatic shutoff device.
The catchment basin is an OPW 1 Spill Container with 5 gallons capacity. A manual drain in the
spill container can be used to drain spilled product back into the tank. If water is present, the spill
container will be manually bailed out.
An 0PW 61-SO two -stage overfill prevention valve serves as both an overfill alarm and automatic
shutoff device. The first stage alerts the transfer operator by reducing the flow rate to
approximately 2 to 5 gallons per minute through a bypass valve. The second stage will
completely cut off flow into the tank by closing the bypass valve if the level approaches a critical
overfill condition. The valve resets itself when the tank level drops -below the critical level.

In addition, the wastewater from the truck wash area (1,170 square feet) is collected and
discharges to the oil/water separator. Any oil or grease picked up by the washwater would be
removed in the oil/water separator before discharging to the sanitary sewer for off -site
treatment.
8.3.3.2 OIL/WATER SEPARATOR
The oiUwater separator is designed to handle 100 gallons per minute (gpm) of wastewater flow.
The oil/water separator has a maximum oil storage capacity of 2,500 gallons and will act as a
containment device to capture accidental oil discharges occurring at the equipment. After oil is
removed in the oil/water separator, the effluent is discharged to the sanitary sewer.
The oil/water separator is installed underground inside a concrete vault. This vault serves as a
secondary containment device to capture any oil discharge from the separator. Any leakage from

Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
8. MEASURES AND CONTROLS
The most effective method to prevent pollution of surface water or ground water is to implement
Best Management Practices (BMPs). BMPs are measures or practices used to reduce the
amount of pollution entering surface water, air, land or ground water. BMPs may take the form of
a process, activity or physical structure. There are three types of BMPs implemented at APCI
industrial gas facilities:
• Baseline BMPs
• Advanced Generic BMPs
• Advanced Site -Specific BMPs
If a particular advanced BMP is implemented at this facility,.the location where it is implemented is
identified in Worksheet B2. For example,. if the BMP described in Section 8.2.1 is implemented at
a bulk storage container, the entry for the storage container in Worksheet 32 will identify "BMP
8.2.1 - Secondary Containment' in the BMP column of the worksheet. Any other applicable
advanced BMPs should also be identified in Worksheet B2. Baseline BMPs will not be identified
in Worksheet B2 since they generally apply to the entire facility and not necessarily to a specific
source.
8.1 BASELINE BEST MANAGEMENT PRACTICES
Baseline BMPs are general practices that apply to most industrial sites, independent of the types
of materials used, processes employed, products manufactured, or site location. Baseline BMPs
are relatively simple, inexpensive, and cost-effective because they emphasize prevention of
pollution rather than treatment of pollutants. The baseline BMPs listed in Section 8.1 are
employed across the entire facility and are not necessarily associated with any specific source of
significant materials listed in Worksheet B2 of Appendix B.
8.1.1 GOOD HOUSEKEEPING
Good housekeeping involves a common sense approach to improve and maintain a clean and
orderly work environment by implementing the following practices:
• Sweeping parking lots
• Storing chemicals in a neat and orderly manner
• Clean up discharges promptly
• Regular refuse pickup and disposal
• Good storage and material inventory practices, including labeling of all containers
• Schedule routine cleanup efforts
• Discuss and promote good housekeeping practices with employees
8.1.2 PREVENTIVE MAINTENANCE
A preventive maintenance program is an effective BMP for preventing surface water or ground
water pollution. A preventive maintenance program should include:
• Timely inspection and maintenance of storm water management devices (e.g., cleaning
oil/water separators, catch basins, etc.)
Rev.:3, Date: 06/23/2008 14

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
• Inspection and testing of facility equipment and systems to uncover conditions that could
cause breakdowns or failures resulting in discharges of pollutants to surface water and
ground water (including pipes, pumps, storage containers and bins, pressure vessels,
pressure release valves, and process and material handling equipment)
• Proper maintenance of facility equipment and systems
8.1.3 RELEASE RESPONSE AND REPORTING PROCEDURES
Effective discharge and release response and reporting procedures are important because they
provide for rapid response to mitigate the impact of the release. Release response and reporting
procedures for this facility are described in more detail in Section 9. These procedures describe
the following measures that will be implemented upon discovery of a significant release:
• Access the risk
• Control the release to the extent possible
• Report the release to management and government agencies
• Clean up the impacted area as soon as possible
• Fallow up with preventive measures
8.1.4 INSPECTIONS
This facility is required to conduct a formal, documented inspection on a semiannual basis during
the spring (April -June) and the fall (September -November) using a copy of Worksheet 82.
Inspection criteria are listed in the instructions to Worksheet B2.
In addition to documented inspections, regular observations of process and material storage
areas are encouraged to ensure that discharges are detected and responded to as in a timely
manner. Observations can be conducted during employees' regular "rounds" of the facility
grounds and need not be formally documented.
8.1.5 OIL HANDLING PERSONNEL TRAINING
Pollution prevention training for oil handling personnel must be held at least annually. Training
must be documented in the facility's training database or in employee records located at the
facility. Personnel are trained in the following areas, with drivers receiving awareness training;
• Release Prevention, Reporting, and Response - a review of emergency procedures,
communications, and reporting and cleanup techniques.
• Pollution Prevention - a review of the purpose, goal, content, and regulatory requirements of
this Plan, potential sources of oil pollution at the site, BMPs implemented at the site, and the
role personnel fulfill in pollution prevention.
• General facility operations
• Operation and maintenance of equipment to prevent oil discharges
• Corporate EH&S Training Package — entitled "Preventing Accidental Pollution of Surface
Waters"
• Discharge Briefings — a discussion of any known discharges or failures, malfunctioning
components, and any recently developed precautionary measures.
Rev.:3, Date: 06/23/2008 15

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
8.1.6 RECORDKEEPING AND INTERNAL REPORTING PROCEDURES
Good record keeping and reporting procedures help to identify and communicate information
about potential sources of surface water and ground water contamination and assure that
appropriate measures are taken. This Plan includes procedures for recording incidents, such as
spills or other discharges, along with other information describing the quality and quantity of
potential pollution sources. All pertinent information regarding a discharge will be documented
and records maintained for three years. Pollution prevention record keeping and reporting are
integrated into current management systems and include:
• The use of the Resource Management System (RMS) preventive maintenance system, or an
equivalent system, for scheduling applicable preventive maintenance tasks and inspections.
• Required reporting of discharges to Line Management, Field EH&S Specialist, and Corporate
EH&S.
• Recording of incidents via the APCI Incident Tracking System
• The periodic review of significant safety and environmental issues or incidents and corrective
action progress by a Line and Staff Management Safety Committee.
8.1.7 SPILL CLEANUP KITS AND MATERIALS
Spill cleanup kits are maintained at the facility. They are routinely inspected to keep them in good
working order. These kits are composed of absorbent sheets, pillows and booms, as appropriate.
In addition, sorbent materials such as oil-dri or vermiculite should be available at all times.
Alkaline neutralizing kits or materials such as soda ash or lime should also be available onsite
from a nearby chemical distributor, for those facilities that use sulfuric acid for cooling water
treatment. Spill cleanup kits or materials are typically maintained within a reasonable distance of
the following areas:
• Truck fueling area and tractor staging/parking
• Truck terminal
• Air Separation Unit (ASU) compressor area/Air Separation Process
• Maintenance buildings and storage areas
• A dedicated spill kit on each truck tractor
• Process equipment with liquid materials in service
• Material loading and unloading areas
8.1.8 EMERGENCY RESPONSE CONTRACTORS
In the event of a discharge, outside assistance for cleanup may be required. Worksheet B4 in
Appendix B lists emergency response contractors located within a reasonable response time from
this facility. The primary emergency response contractor has provided information regarding
qualifications (availability of the necessary personnel and equipment within appropriate response
time). Worksheet B10 in Appendix B has been completed by the response contractor and has
been inserted in the Plan.
8.1.9 EMERGENCY PREPAREDNESS AND COMMUNICATIONS
This facility shall have a Site Emergency Plan prepared in accordance with the Gases and
Equipment Group (GEG) EH&S Procedure 01.08.02, "Site Emergency Planning". Additionally,
GEG EH&S Procedures 01.08.05.A.M., "Crisis Management" and 01.08.16.A.M., "HAZWOPER"
Rev.:3, Date: 06/23/2008 16

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
address emergency preparedness. These procedures can be found in the GEG Worldwide
Operations and Distribution Manual.
8.1.10 SECURITY
This facility is completed surrounded by a security fence. Access to the site is controlled through
a main gate. Entry through this gate can be made only by a security access code or through
permission received from the Control Room. Storage containers, secondary containment
systems, process areas and piping systems are confined within the fence line. The area is lighted
and is subject to typical facility security measures, including restricted vehicular traffic.
8.2 ADVANCED GENERIC BEST MANAGEMENT PRACTICES
Advanced generic BMPs are generic measures or practices that are employed to address specific
sources, materials, or activities that may be present at the facility. They include generic
prevention, containment, and mitigation practices that can be applied to specific sources (e.g.,
fueling stations) commonly found at APCI industrial gas facilities. Section 8.2 provides a
reference list of generic BMPs that may be used at industrial gas facilities. Those source -specific
BMPs that are actually implemented at this facility, and the locations where they are implemented,
are listed in Worksheet B2 of Appendix B.
8.2.1 SECONDARY CONTAINMENT
Secondary containment systems are effective in controlling discharges. To be most effective,
secondary containment systems and diversionary structures should meet the following standards:
• The systems black possible routes by which discharged materials could reasonably be
expected to flow, migrate, or escape into surface waters or upon the land from within the
containment areas. Manually operated valves are normally in a closed position and locked.
• The secondary containment systems have sufficient capacity to contain the largest probable
discharge that could occur in the containment area plus an additional capacity to compensate
for anticipated normal accumulation of rainwater.
• The secondary containment system is sufficiently impermeable to contain discharged material
for a duration necessary for the cleanup or recovery of the discharged substance.
• The secondary containment system is routinely inspected for accumulated liquids, debris, or
incompatible materials.
No transfer area, curbed storage area, or secondary containment system is drained into a
watercourse or public sewage treatment plant unless provision is made to retain, by secured
valves or other means, any accumulated rainwater until its condition can be determined.
Adequate records are to be kept for discharges of uncontaminated rainwater.
No incompatible materials are stored within the same containment area.
8.2.2 LOADING AND UNLOADING OPERATIONS
The following measures are key to preventing the release of significant materials during transfer
operations:
Rev.:3, Date: 06/23/2008 17

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
• Training - Prevention of the release of materials during transfer operation is accomplished
through implementing procedures discussed during personnel training programs, regular
safety meetings, and briefings.
• Vehicle positioning - Whenever possible, vehicles should be positioned within spill
containment areas during transfer. Positioning near or over storm drains or sewer drains
should be avoided. Wheel blocks and emergency brakes should be used to avoid sudden
movement of the vehicle. If the vehicle is positioned near a traffic corridor, traffic barriers
should be placed to avoid collisions.
• Ere -positioning of spill kits booms or sewer block mats - if secondary containment is not
available during loading or unloading, spill kits must be readily available and spill mats or
booms should be pre -positioned to seal any nearby catch basins that could lead directly to
surface water or sewer systems. The discharge diversionary measure should be capable of
containing the maximum capacity of a single compartment of the vehicle being loaded or
unloaded.
• Pre -inspection of connections fittings, and hoses - Prior to each transfer operation,
connections, hoses, gaskets and fittings must be checked to ensure they are in good working
condition. Loading and unloading areas must be well illuminated if material transfer occurs at
night.
• Drip pans - Drip pans or buckets must be used to catch small volume leakage from transfer
hoses or fittings during transfer operations. Captured materials should be reused or properly
disposed.
• Overfill prevention - During a delivery, tank truck operators must be instructed to remain with
the vehicle along with at least one qualified facility employee. Before a delivery, the liquid
level in the receiving container is checked. Employee training procedures include instructing
operators not to leave the delivery area prior to checking and disconnecting the transfer line.
Prior to material transfer, qualified facility personnel and the driver are instructed to:
♦ Predetermine the maximum volume of material that can be transferred without overfilling
the container.
♦ Check the liquid level in the container(s) during transfer to avoid overfilling the container.
• Prior to departure — Qualified personnel and the driver are instructed to:
♦ Inspect the area for any sign of discharge. Control, report and clean up discharges
immediately.
♦ Ensure that all outlets from both the delivery vehicle and container have been tightened,
adjusted, or replaced to prevent a discharge.
8.2.3 ABOVEGROUND BULK STORAGE CONTAINERS
The following practices should be implemented for aboveground bulk storage containers
(specifically aboveground tanks):
• All pipes leading to and from aboveground bulk storage container(s) that enter the
container(s) below liquid level are equipped with valves sufficiently close to the container so
as to prevent the contents of a container from escaping the confines of the secondary
containment area in the event of a pipe rupture outside of the containment area. Any valves
Rev.:3, Date: 06/23/2008 18

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
- - Storm Water Pollution Prevention Plan
that permit the direct outward flow of container contents are kept in the closed position when
in non -operating or standby status.
In heavy traffic areas, protective guards or bollards should be placed around tanks and piping
to prevent vehicle or forklift damage. Piping runs are above standard truck height and behind
barriers.
• Containers, associated valves and piping should be clearly labeled to reduce human error.
• Containers are compatible with the material stored and the conditions of storage.
• Containers, associated piping, supports, and foundations must be routinely inspected for
integrity. Integrity testing is any means to measure the strength of the container shell and
may include leak testing to determine whether the container will discharge oil. Visual testing
in conjunction with another method of testing is required. Monthly visual inspections alone
might suffice in accordance with the deviation provision in section 112.7(a)(2), subject to good
engineering practice if:
0 Internal corrosion poses minimal risk
0 Visual inspections conducted at least monthly
0 All sides are visible, and
0 Containers have no contact with the ground
• Containers in contact with the ground must be evaluated for integrity in accordance with
industry standards and good engineering practice.
8.2.4 FUELING STATIONS
The following practices should be implemented at fueling stations:
• Avoid topping off - To minimize overfilling of truck fuel tanks, special fill procedures must be
followed to ensure that there is adequate room for expansion of cooler diesel fuel drawn from
underground tanks when it is placed in the truck saddle tanks and cryogenic delivery pump
engines. Hot summer weather greatly increases the potential for overflow of vehicle fuel
tanks that have been overfilled. To avoid this condition, the fuel tank should not be filled
above the neck on the fuel tank.
• Avoid, unattended filling - When refueling vehicles, the driver must hold the fuel nozzle in hand
during the entire refueling operation, even if the fuel nozzle has an automatic shutoff device.
• Avoid hosing down - Cleaning the fueling area with running water should be avoided because
the wash water will pick up fuel, oil and grease. Use dry clean-up methods whenever
possible. Control and clean up petroleum discharges immediately.
• Keen mill kits accessible - An adequate supply of spill kit materials should be available before
fueling vehicle. Control, report and clean up petroleum discharges immediately.
• Minimize storm water run-on - Minimize storm water run-on to the fueling area through flow
diversion around the fueling station and using roofs over the fueling area when feasible.

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
8.2.5 VEHICLE MAINTENANCE AND REPAIR
Many vehicle and equipment maintenance operations use materials that can be harmful to the
environment. The following practices should be followed at vehicle and equipment maintenance
operations to reduce or eliminate potential sources of pollution:
• Parts washing - Clean without using liquids (e.g., scraper, wire brush) whenever possible. Do
all liquid cleaning at a centralized station so solvents and residues stay in one area.
• Use nontoxic or low toxicity solvents - Minimize the number and volume of hazardous
materials used. Avoid chlorinated solvents. Choose cleaning agents that can be recycled,
• Control discharges - Collect leaking fluids in -drip pans. Keep a drip pan under the vehicle
while unclipping hoses, unscrewing filters, or removing parts. Control discharges from
wrecked or damaged equipment that may be stored outdoors. Promptly transfer used fluids
to proper waste or recycling containers. Do not leave full drip pans lying around.
• Drain oil filters - Used oil filters disposed of in trash cans can leak oil and contaminate surface
water. Place used oil filters in a funnel over the waste oil recycling or disposal collection tank
to drain excess oil before disposal. Whenever possible, crush and recycle oil filters.
• Never pour liquid wastes into drains or onto the ground - Do not pour liquid waste to floor
drains, sinks, outdoor storm drains, or sewer connections.
• Fiecyale materials - Whenever possible, recycle degreasers, used oil and oil filters, antifreeze,
cleaning solutions, automotive batteries, hydraulic fluid and tires.
• Segregate and label wastes - Separating wastes allows easier recycling and may reduce
treatment costs. Locate waste and recycling containers in clearly marked and controlled
areas.
8.2.6 VEHICLE AND EQUIPMENT WASHING
Washing vehicles and equipment outdoors or in areas where wash water can flow onto the
ground can pollute surface waters or ground waters. Wash water can contain high. concentrations
of oil and grease, phosphates, and suspended solids. To reduce or eliminate these potential
sources of pollution:
• Use designated cleaning areas only. Wash water is regulated as a process waste water. It
can only be discharged to a properly permitted sanitary sewer or process sewer line.
• if a permitted sewer line is not available, wash water should be collected in bermed areas or
sumps for offsite disposal.
• As an alternative, offsite commercial washing facilities can be used.
8.2.7 WASTE MANAGEMENT AREAS
Wastes discharged, leaked or lost from waste management areas may build up in soils or be
carried away by rainfall. To reduce the potential for pollution, the following practices should be
implemented:
• Minimize the amount of waste managed on -site.
• Prevent run-off and run-on from contacting waste management areas.
Rev.:3, Date: 06/23/2008 20

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water Pollution Prevention Plan
Keep waste containers closed or securely covered.
8.2.8 TRANSFORMERS
The following practices should be implemented in transformer yard areas:
• Transformers should be inspected periodically for evidence of discharges.
• Discharges must be cleaned up as soon as possible.
• Adequate spill kit materials should be available to prevent a discharge from reaching a
waterway.
8.2.9 OIL/WATER SEPARATORS
The following practices should be implemented to assure proper operation of an oil/water
separator unit:
• The level of oil captured in the unit should be routinely monitored and removed by a properly
permitted used oil vendor.
• Any associated oil skimmers should be checked for proper operation.
• The waste water effluent from the unit should be routinely observed or monitored to determine
if the unit is functioning properly.
• The unit should be periodically cleaned to remove accumulated solids on the bottom of the
unit and on any coalescing plates.
• Discharges must be cleaned up as soon as possible.
• The discharge of solids and detergents to the oil/water separator should be minimized.
8.2.10 GREASE TRAPS AND GRIT CHAMBERS
The following practices should be implemented to assure proper operation of grease traps and grit
chambers:
• The levels of accumulated oil and solids should be routinely monitored and removed for
proper disposal.
• Any associated oil skimmers should be checked for proper operation.
• The waste water effluent from the unit should be routinely observed or monitored to determine
if the unit is functioning properly.
• Discharges must be cleaned up as soon as possible,
8.2.11 DRUMS AND BULK CONTAINER STORAGE AREAS
The following practices must be implemented at drum and bulk container ("drums") storage areas:
• The contents of all drums must be properly identified by a label.
Rev.:3, Date: 06/23/2008 21

Reidsville, NC Facility
Spill Prevention Control and Countermeasure Plan
Storm Water_ Pollution Prevention Plan
• Drums that are stored in a horizontal position must be tightly sealed to avoid seepage through
the bung. Drip pans should be placed beneath horizontal drums that have a dispensing valve
installed.
• Drums should be kept closed except when material is being added or withdrawn.
• For drums stored outdoors, drums caps must be used to avoid accumulated rainwater on the
top lip of the drum causing contamination of the product. Outdoor drums must be stored off
of the ground to prevent bottom corrosion and possible leakage from the drum. Wooden
pallets may be used if an impervious surface is not available.
• Drums should be neatly stored with sufficient access and aisle space.
• Because empty drums often contain residual product, they must be managed according to the
practices listed above, unless they have been thoroughly cleaned.
• Leaking drums must be immediately moved to a containment area, placed in a salvage drum,
plugged, or the contents transferred into another drum. Discharged product must be cleaned
up immediately.
• Drums must be routinely inspected for integrity. Integrity testing is any means to measure the
strength of the container shell and may include leak testing to determine whether the
container will discharge oil. Visual testing in conjunction with another method of testing is
required. Monthly visual inspections alone might suffice in accordance with the deviation
provision in section 112.7(a)(2), subject to good engineering practice if:
0 Internal corrosion poses minimal risk
0 Visual inspections conducted at least monthly
0 All sides visible and/or drum storage area is located away from vehicular traffic, and
where discharges would be visible would not readily enter into a waterway conveyance
(i.e. surface water, sewer system)
0 Containers have no contact with the ground
• Containers in contact with the ground must be evaluated for integrity in accordance with
industry standards and good engineering practice.
8.2.12 SEDIMENT AND EROSION PREVENTION
The following practices should be implemented in areas of high soil erosion potential or during
construction periods:
• Preserve existing vegetation or revegetate disturbed soil areas.
• Stabilize stream banks.
• Install interceptor dikes and swales.
• Use fabric filter fences around disturbed areas.
• Maintain storm water retention/detention ponds in good operating condition.
8.2.13 SARA 313 WATER PRIORITY CHEMICALS
Facilities subject to reporting under SARA Section 313 for water priority chemicals may be
required to implement special BMPs for storm water pollution prevention. Any applicable, special
BMPs are further described in Sections 10.5.2.through 10.5.7. They must be implemented in
areas where storm water can come in contact with SARA Section 313 water priority chemicals.

8.3 ADVANCED SITE SPECIFIC BEST MANAGEMENT PRACTICES
Advanced site -specific BMPs are measures or practices that are implemented at specific
locations at this facility. They include such BMPs for oil/water separators, bulk storage containers,
operating and electrical equipment, or underground storage tank leak detection monitoring. Any
deviations from the SPCC requirements will be documented, explaining the nonconformance and
providing equivalent environmental protection by some other means. Examples may include
measures for containment or diversionary structures and integrity testing. Site -specific BMPs
implemented at this facility are described in Section 8.3 and the locations where they are
implemented are identified in Worksheet B2 of Appendix B.
8.3.1 TRUCK FUEL UNDERGROUND STORAGE TANK SYSTEM
The truck fuel underground storage tank system consists of two 10,000 gallon diesel fuel
underground storage tanks (USTs), submersible pumps with underground pressurized piping,
leak detection system, spill and overfill prevention devices, and an associated fuel dispensing
island. The tanks were installed in 1992.
The red jacket pump for the diesel oil system is equipped with an automatic line leak detector flow
restrictor that dramatically cuts the flow through the piping when the unit senses a leak. The
double walled fiberglass piping has an interstitial leak detection monitor in the form of a piping
sensor.
Tank Level Monitoring Svstem
The ATG is a Veeder-Root TLS-350 equipped with a continuous statistical leak detection (CSLD)
tank level monitoring system. The system includes a sensing probe in the tank and a remote
monitor with printer. The system provides continuous monitoring of product level, water level, and
product temperature. Whenever the fueling system is idle, the TLS-350 collects data and
performs a statistical analysis to detect leaks as small as 0.2 gallons per hour. There is no need
to shut down the fueling system for the leak detection test. Leak tests are constantly being
performed, and test results are automatically provided every 24-hour period, or on demand from
the console printer.
In addition to serving as a leak detection device, the Veeder-Root TLS-350 level monitor also
serves as a high level alarm. A red alarm light is remotely mounted at the fueling island to
indicate an overfill condition.
Spill Containment and Overfill Protection
To prevent surface spills and tank overfills, each tank is equipped with a catchment basin, overfill
alarm, and automatic shutoff device.
The catchment basin is an OPW 1 Spill Container with 5 gallons capacity. A manual drain in the
spill container can be used to drain spilled product back into the tank. If water is present, the spill
container will be manually bailed out.
An OPW 61--SO two -stage overfill prevention valve serves as both an overfill alarm and automatic
shutoff device. The first stage alerts the transfer operator by reducing the flow rate to
approximately 2 to 5 gallons per minute through a bypass valve. The second stage will
completely cut off flow into the tank by closing the bypass valve if the level approaches a critical
overfill condition. The valve resets itself when the tank level drops below the critical level.

Storm Water Pollution Prevention Plan
Any spills that occur on the'concrete fueling station pad drain to the 14.50 Oil/Water Separator
where the spilled product is captured -and can be removed. (See Section 8.3.3)
Dispensing System
The fuel dispenser is mounted on a Total Containment dispenser sump to contain any spills or
leaks from the dispenser or associated piping. It serves as a termination point for the double -
walled fiberglass piping from the submersible sump pump to the fuel dispenser.
8.3.2 HEATING OIL UST
The Heating oil tank was installed in 1992 and is a 2,500 gallon UST with a submersible pump
with pressurized piping.
8.3.3 OILY WATER CONTROL SYSTEM -
8.3.3.1 POLLUTANT SOURCES
Contaminated rainwater run-off from the foundations of the following equipment discharges to the
oil/water separator for treatment prior to discharge from the facility:
• Truck Fueling Station (See Section 8.3.1)
• 1CP-K111 Main Air Compressor, Motor, Lube Oil System (665 gals.)
• 1 CP-K301 /321 Recycle/Make-up LOS (565 gals.)
• 1 CS-T361 Compander (250 gals)
• 01.16F Main Air Compressor (300 gals)
• 01.30F Recycle (300 gals)
• 01.46F Recycle (1,000 gals)
• 01.14A Com pander (450 gals)
In addition, the washwater from the truck wash area (1,170 square feet) is collected and
discharges to the oil/water separator. Any oil or grease picked up by the washwater would be
removed in the oil/water separator before discharging to the sanitary sewer for off -site
treatment.
8.3.3.2 OILIWATER SEPARATOR
The oiVwater separator is designed to handle 100 gallons per minute (gpm) of wastewater flow.
The oil/water separator has a maximum oil storage capacity of 2,500 gallons and will act as a
containment device to capture accidental oil discharges occurring at the equipment. After oil is
removed in the oil/water separator, the effluent is discharged to the sanitary sewer.
The oil/water separator is installed underground inside a concrete vault. This vault serves as a
secondary containment device to capture any oil discharge from the separator. Any leakage from

Storm Water Pollution Prevention Plan
the unit is unlikely. In the event of a small leakage into the concrete vault, sorbent materials shall
be used to clean up the oil. The concrete vault should be monitored weekly to check for any
leakage of oil.
Oil will periodically be removed from the side -oil storage reservoir for proper disposal in
compliance with environmental regulations. Any small spills related to a waste oil vendor pumping
the stored oil from the oil/water separator would be cleaned up using sorbent materials. A large
spill could be prevented from reaching a storm drain through the use of oil booms.
8.3.4 COOLING WATER TREATMENT BUILDING
A small building adjacent to the cooling tower houses a small tank and drums of water treatment
chemicals. Floor drains that lead to the sanitary sewer should be plugged under normal
conditions. Major discharges of water treatment chemicals should be recovered and reused in the
cooling tower. The majority of these treatment chemicals do not contain petroleum products or
oils and are not required to be covered by this SPCC Plan.
8.3.5 ABOVEGROUND BULK STORAGE OIL CONTAINERS
8.3.5.1 SHOP FABRICATED TANKS
There is a 375 gallon double -walled aboveground storage tank for temporary storage of used
motor oil from the routine maintenance of the truck fleet. This tank is located outdoors at the west
end of truck garage bay. This tank was installed in 1992.
The container is a lube cube oil container and is UL 142 listed and meets fire code requirements,
including NFPA 30 for flammable and combustible liquid storage. The double -walled container is
UL listed as integral secondary containment and therefore does not require a dike for leak
containment.
The welds of the primary container are continuous, and the material of construction is ASTM A-
569 or A-36 carbon steel. The primary container is pressure tested in the factory to UL 142 specs
(3 PSI). The primary tank exterior is painted with one coat of shop primer. There is a minimum of
2 support feet.
The secondary (double -wall) container is UL 142 listed, and welds are continuous. The double -
wall provides a minimum of 110% secondary containment. The exterior and portion of the
exposed primary container is painted with one coat of shop primer. The secondary containment is
tank pressure tested at the factory to UL 142 specs.
8.3.5.2 OIL DRUMS
Oil containers are of carbon steel construction. The tight -head unlined drums meet UN packaging
standards (UN 1AVY1.8/300) for shipping of hazardous materials and are ambient air tested to
reject leaking containers. Two expanded rolling hoops provide freight utilization and vacuum
resistance. Surfaces are prepared for optimum paint adhesion and are tested for resistance to
heat and abrasion, color stability, impact and corrosion resistance.

Dear Mr. Eberle:
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.
The draft permit contains the following significant changes from this facility's current permit:
• Analytical monitoring frequency for all parameters has changed to semi-annual (once in the
spring and once in the fall). This change reflects the Division's revised strategy for renewal
permits and makes stormwater sampling frequency consistent with qualitative monitoring.
Semi-annual monitoring is in both Sections B and D (Vehicle Maintenance) of Part H.
• The Division has incorporated benchmark values into the permit. These benchmarks are not
permit limits but should be used as guidelines for your facility's Stormwater Pollution Prevention
Plan (SPPP). If any measurements exceed benchmark values, your facility should evaluate the
effectiveness of its Best Management Practices (BMPs), review and/or update its SPPP, and
document any efforts to address stormwater contamination (see Part 11, Sections B and D).
• In Part H, Section B, Total Phosphorus (TP) and TSS monitoring have been removed. COD
monitoring is required for at least two more years (See footnote 4 under Table 1).
• TMDL (Total Maximum Daily Load) language has been incorporated into the same section under
Table 3 (Part II, Section B) because Little Troublesome Creek is on the 303(d) list of impaired
waters and has an approved TMDL for fecal coliform bacteria. No special monitoring is required
at this time.
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount and
Rainfall Event Duration be recorded for each sampling event. This change is also based on the
Division's revised strategy for stormwater monitoring in renewal permits. Please note that the
Stormwater Pollution Prevention Plan (SPPP) site map must include drainage area for each
outfall in acres and the percentage of each drainage area that is impervious (see Part II, Sec. A).

documentingividual 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.

This site discharges to impair waters experiencing problems with fecal coliform and impaired
biological integrity, and to waters upstream of the Haw River Arm of the Jordan Reservoir,
experiencing problems with nutrients and chlorophyll a violations (indicative of excessive
nutrient loads). A Total Maximum Daily Load (TMDL) for fecal coliform was approved in May
2002 for Little Troublesome Creek, but the Permittee was not allocated a load for stormwater
discharge and is not required to monitor for fecal coliform at this time.
If additional TMDLs are approved for this segment of Little Troublesome Creek, the Permittee
may be required to monitor for the pollutant(s) of concern in the future and submit results to the
Division of Water Quality. The Division will consider the monitoring results in determining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level of control, the Permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the permitted Stormwater Pollution Prevention
Plan.

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 4. 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 is performed when stormwater
discharge occurs but 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
Plan. & ,e
All qualitative monitoring will be performed twice per yeg"OiceTin. tffe spring (April - June) and

footnote explains that if all values below 120 mg/l, site may
discontinue monitoring for remainder of the permit.
All monitoring has changed to Semi -Annual (spring and fall). This
change is based on the Division's revised strategy for stormwater
monitoring in renewal permits and makes stormwater discharge
L�sampling frequency consistent with qualitative monitoring. In
addition, DWQ has incorporated benchmark values into the permit.
These benchmarks are not permit limits but should be used as
guidelines for the facility's Stormwater Pollution Prevention Plan
(SPPP). New language specifies that if any measurements exceed
benchmark values, the facility should evaluate the effectiveness of its
BMPs, review and/or update its SPPP, and document any efforts to
address stormwater contamination (see Part 1I, Sec. B & D).
Total Flow monitoring has been removed per DWQ revised strategy
(Total Rainfall and Event Duration parameters retained). Instead, Part
H. Sec. A clarifies that SPPP site map include drainage area for each
outfall in acres and percent impervious area in each drainage area
(should flow ever need to be estimated).
Basis for Other Requirements: T`MDL language added in Part II, Section B---impaired stream

DOCUMENTS REVIEWED
NPDES Stormwater Permit Application Materials
S/W Permit File
Analytical &Qualitative Monitoring Results summary
Cape Fear Basinwide Plan (rev. July 2000) & Draft Plan (rev. March 2005, out for
Central Office Review Summary:
Since last renewal, the company has had no significant changes in industrial activities. This site compresses,
liquefies, and distills components of the incoming air stream into liquid nitrogen, oxygen, and argon.
Facility discharges stormwater into impaired waters. Little Troublesome Creek was added to the 303(d) list
because of impaired biological integrity (and further downstream of Reidsville WWTP, fecal coliform). The
potential sources noted are urban runoff and storm sewers. A fecal TMDL for Little Troublesome Creek was
approved in May 2002, but no loads were allocated to any permitted point source dischargers (would include
NPDES Stormwater discharges), and activities at this site should not be a significant source of the bacteria.
The Draft 2005 Cape Fear Basinwide Plan cites the November 2002 WARP Study that identified toxicity, organic
enrichment, and habitat degradation from impervious surface runoff, urban development, unpaved roads, road
construction, and cropland and streambank erosion as the biological community stressors in the stream. Also,
Stormwater discharges throughout this sub -basin potentially contribute nutrients downstream to the Haw River
Arm of Jordan Lake Reservoir, impaired from chlorophyll a violations. The Jordan Reservoir and Haw River
Nutrient Sensitive Waters (NSW) Management Strategy and TMDL for the Upper New Hope Arm resulted in
nitrogen and phosphorus loading limits for the Reidsville WWTP wastewater discharge. Current recommendations
are also for all local governments in the Haw River Arm watershed to meet NPDES Phase II Stormwater
requirements and to achieve stormwater TN & TP export performance goals for new and existing development.
This is important for the Air Products facility for two reasons: It is located in Reidsville, a municipality not
automatically designated in Phase II, but one that will probably be brought in as a result of NSW Management
Strategy requirements for the Cape Fear Basin; also, the activities at this site are a potential source of nitrogen.
Qualitative Monitoring Results: Permittee sent results from 1999-04. No problems observed.
Analytical Monitoring: See attached Monitoring Data Analysis. Permittee's outfall 001 was granted
representative status in 1995 (letter attached). Recommend removing TP (not a significant source of phosphorus)
but retaining TN monitoring (maximum close to benchmark of 30 mg/1) because of nutrient concerns in this
watershed. Also removed TSS monitoring because values were well below benchmark (1999 permit reviewer noted
more data needed to definitely rule out need for monitoring). Probably not necessary to include pH monitoring for
this site.
For this industry sector, the EPA Multi -Sector permit includes monitoring for total recoverable Aluminum and
Iron, but these are not pollutants of concern at this facility. Nitratefnitrite monitoring would also not apply.
Monitoring frequency will increase to semi-annually. This change ensures at least nine data points are collected
through the permit term and makes monitoring frequency consistent with qualitative monitoring. Also, benchmark
values for all parameters have also been added to the permit as a guide for the permittee to check the effectiveness
of BMPs (and document efforts) when necessary. Because TN monitoring is based on a potential source, a
benchmark concentration for this nutrient is included (would not be if only monitoring to collect data).
COD levels decreased markedly since I999 (from 142 to <25 mg/I). Facility has made significant efforts to
eliminate several chemicals on site and improved storage practices the past few years, though it's not certain if
anything specifically removed the source. Because quarterly monitoring during 2002-03 recorded four values,
reviewer recommends keeping COD monitoring (semi-annual) for at least two more years to collect four
additional data points. Site may discontinue monitoring if no values are above the benchmark.

NCS000030
Follow-up with the company contact (David Eberle, 336-342-231 I) on 5/ 17/2005:
+ There are vehicle maintenance activities at this site with oil usage exceeding 55 gal/mo. (tractor
maintenance); however, any spilled oil or other runoff in this area drains to the oil/water separator
and into the sanitary sewer. All used oil is collected by a vendor. No stormwater runoff contacts
residue from these activities.
• COD was in the 100s back in 1994 and 1999 (116 and 142 mg/l, resp.), but 2002-03 monitoring showed
substantial decrease (<30 mg/1). Any particular reason or different BMPs?
Not sure. [Talked with Environmental Engineer for the site, Damian Marcinek (610-48I -5766) on 5/ 17.
Company has been in the process of eliminating several chemicals on site and has re-examined its storage
practices the past few years. Probably no one particular change, but reinforcing BMPs already in place has
hopefully made the difference. Site was concerned when COD jumped up in 1999.]
+ Any other chemicals stored outside besides diesel fuel and liquid N2, 02, and Ar?
No. All diesel fuel tanks are now underground and monitored around the clock.
Recommendation: Based on the documents reviewed, the application information submitted on October 22, 2004
is sufficient to issue an Individual Stormwater Permit.

Dear Mr. Evans;
Enclosed please find the storm 'water permit renewal package for our facility at 225 Equity Road,
Reidsville, NC. There have not been any significant changes in the industrial activities at the site -
since our previous permit application. One change that has occurred is that we no longer store or
use sulfuric._acid fort industrial water-,treatrnent'at
The monitoring summary enclosed contains data from 2 monitoring events, the initial monitoring
conducted in 1994 and the recent monitoring in 1999. Our initial monitoring event met the
specified cutoff concentrations and no additional samples were taken until the current year, Also,
we were unable to locate the visual monitoring results for 1995, the results from the.other years are
included in the summary. The monitoring was conducted at outfall 001 as we were granted a
identical outfall exemption and were authorized to sample only that outfall as representative of
runoff at our site. A copy of that authorization letter is enclosed.

Your request to sample the stormwater discharge outfall 001 on your site fo"r puiposes of NPDES
stormwater general permit monitoring requirements has been reviewed by members of the Water Quality
Section staff. Your request described two (2) outfalls of which are associated with substantially identical
industrial activities and runoff from non -industrial areas.
Based upon staff review of your letter dated January 16, 1995, and attached site map, we have
concluded that the requested determination is warranted and in accordance with Chapter 40 of the Code of
Federal Regulation part 122.21 (g) (7). We authorize you to sample at outfall 001 as stormwater
discharges representative of the runoff from the Air Products and Chemicals, Inc.; facility for your
NPDES stormwater general permit monitoring requirements.
If you have any questions concerning this authorization, please contact Steve Ulmer at (919) 733-
5083

1.1 BASELINE BEST MANAGEMENT PRACTICES
Baseline BMPs are general practices that apply to most industrial sites, independent of the types
of materials used, processes employed, products manufactured, or site location. Baseline BMPs
are relatively simple, inexpensive, and cost-effective because they emphasize prevention of
pollution rather than treatment of pollutants. The baseline BMPs listed in Section 8.1 are
employed across the entire facility and are not necessarily associated with any specific source of
significant materials listed in Worksheet B2 of Appendix B.
1.1.1 GOOD HOUSEKEEPING
Good housekeeping involves a common sense approach to improve and maintain a clean and
orderly work environment by implementing the following practices:
• Sweeping parking lots
• Storing chemicals in a neat and orderly manner
• Clean up small spills promptly
• regular refuse pickup and disposal
• Good storage and material inventory practices, including labeling of all containers
• Schedule routine cleanup efforts
• Discuss and promote good housekeeping practices with employees
1.1.2 PREVENTIVE MAINTENANCE
A preventive maintenance program is an effective BMP for preventing surface or ground water
pollution_ A preventive maintenance program should include:
• Timely inspection and maintenance of storm water management devices (e.g.. cleaning
oil/water separators, catch basins, etc.)
• Inspection and testing of facility equipment and systems to uncover conditions that could
cause breakdowns or failures resulting in discharges of pollutants to surface water and
ground water (including pipes, pumps, storage tanks and bins, pressure vessels, pressure
release valves, and process and material handling equipment)
• Proper maintenance of facility equipment and systems
1.1.3 RELEASE RESPONSE AND REPORTING PROCEDURES
Effective spill and release response and reponing procedures are important because they provide
for rapid response to mitigate the impact of the release. Release response and reporting
procedures for this facility are described in more detail in Section 9. These procedures describe
the following measures that will be implemented upon discovery of a significant release:
• Access the risk
• Control the release to the extent possible
• Report the release to management and government agencies
• Clean up the impacted area as soon as possible
• Follow up with preventive measures

1.1.4 INSPECTIONS
This facility is required to conduct a formal, documented inspection on a semiannual basis using
a copy of Worksheet B2. Inspection criteria is listed in the instructions to Worksheet B2_
In addition to documented inspections, regular observations of process and material storage
areas are encouraged to ensure that spills are detected and responded to as in a timely manner.
Observations can be conducted during employees' regular "rounds" of the facility grounds and
need not be formally documented.
1.1.5 EMPLOYEE TRAINING
Pollution prevention training for employees should be held annually. Training should be
documented in the facility's training database or in employee records located at the facility.
Employees are trained in the following areas:
• Release Prevention, Reporting, and Response - a review of emergency procedures,
communications, reporting and cleanup techniques.
• Pollution Prevention - a review of the purpose and goal of this Plan, potential sources of storm
water oollution at the site, BMPs implemented at the site, and the role employees fulfill in
pollution prevention.
1.1.6 RECORDKEEPING AND INTERNAL REPORTING PROCEDURES
Good recordkeeping and reporting procedures help to identify and communicate information
about potential sources of surface water and ground water contamination and assure that
appropriate measures are taken. This Plan includes procedures for recording incidents, such as
spills or other discharges, along with other information describing the.quality and quantity of
potential pollution sources. Ail pertinent information regarding a spill will be documented and
records maintained for three years. Pollution prevention recordkeeping and reporting are
integrated into current management systems and include:
• The use of the RMS preventive maintenance system, or an equivalent system, for scheduling
applicable preventive maintenance tasks and inspections.
• Required reporting of spills and leaks to Line Management, Facility Environmental
Coordinator, and Corporate EH&S_
• The periodic review of significant safety and environmental issues or incidents and corrective
action progress by a Line and Staff Management Safety Committee_
1.1.7 SPILL CLEANUP KITS AND MATERIALS
Spill cleanup kits are maintained at the facility. They are routinely inspected to keep them in good
workino order. These kits are composed of absorbent sheets, pillows and booms, as appropriate.
In addition, sorbent materials such as oil -dry or vermiculite should be available at all times.
Alkaline neutralizing kits or materials such as soda ash or lime should also be available onsite
from a nearby chemical distributor, for those facilities that use sulfuric acid for cooling water
treatment. Spill cleanup kits or materials are typically maintained within a reasonable distance of
the following areas:
• Truck fueling area
• Truck terminal

• Air Separation Unit (ASU) compressor area/Air Separation Process
• Maintenance buildings or areas
• A dedicated spill kit on each truck tractor
1.1.8 SPILL CLEANUP CONTRACTORS
In the event of a spill, outside assistance for cleanup may be required_ Worksheet B4 in Appendix
B lists emergency response contractors located within a reasonable response time from this
facility.
1.1.9 EMERGENCY PREPAREDNESS AND COMMUNICATIONS
This facility shall have a Site Emergency Plan prepared in accordance with GEG EH&S Procedure
01.08.02.A, "Site Emergency Planning". Additionally, GEG EH&S Procedures 01.08.05.A.M.,
"Crisis Management" and 01.08.16.A.M., "HAZWOPER" address emergency preparedness.
These procedures can be found in the GEG EH&S Manual.
1.1.10 SECURITY
This facility is completed surrounded by a security fence. Access to the site is controlled through
a main gate. Entry through this gate can be made only by a security access code or through
permission received from the Control Room. Storage tanks, secondary containment systems,
process areas and piping systems are confined within the fenceline. The area is lighted and is
subject to typical facility security measures, including restricted vehicular traffic.
1.2 ADVANCED GENERIC BEST MANAGEMENT PRACTICES
Advanced generic BMPs are generic measures or practices that are employed to address specific
sources, materials, or activities that may be present at the facility. They include generic
prevention, containment, and mitigation practices that can be applied to specific sources (e.g.,
fueling stations) commonly found at Air Products industrial gas facilities_ Section 9_2 provides a
reference list of generic BMPs that may be used at industrial gas facilities. Those source -specific
BMPs that are actually implemented at this facility, and the locations where they are implemented,
are listed in Worksheet B2 of Appendix B.
1.2.1 SECONDARY CONTAINMENT
Secondary containment systems are effective in controlling spills. To be most effective,
secondary containment systems and diversionary structures should meet the following standards:
• The systems block possible routes by which spilled materials could reasonably be expected to
flow, migrate, or escape into surface waters or upon the land from within the containment
areas.
• The secondary containment systems have sufficient capacity to contain the largest probable
spill that could occur in the containment area plus an additional capacity to compensate for
anticipated normal accumulation of rainwater.
• The secondary containment system is sufficiently impermeable to contain spilled material for
a duration necessary for the cleanup or recovery of the spilled substance.
• The secondary containment system is routinely inspected for accumulated liquids, debris, or
incompatible materials.

No transfer area, curbed storage area, or secondary containment system is drained into a
Watercourse or public sewage treatment plant unless provision is made to retain, by valves or
other means, any accumulated rainwater until its condition can be determined.
• No incompatible materials are stored within the same containment area.
1.2.2 LOADING AND UNLOADING OPERATIONS
The following measures are key to preventing the release of significant materials during transfer
operations:
• Training - Prevention of the release of materials during transfer operation is accomplished
through implementing procedures discussed during personnel training programs, regular
safety meetings, and briefings.
• Vehicle positioning - Whenever possible, vehicles should be positioned within spill
containment areas during transfer. Positioning near or over storm drains or sewer drains
should be avoided. Wheel blocks and emergency brakes should be used to avoid sudden
movement of the vehicle. If the vehicle is positioned near a traffic corridor, traffic barriers
should be placed to avoid collisions.
• Pre -positioning of spill kits booms or sewer block mats - It secondary containment is not
available during loading or unloading, spill mats or booms must be readily available or pre -
positioned to seal any nearby catch basins that could lead directly to surface water or sewer
systems.
• Pre -inspection of connections, fittings, and hoses - Prior to each unloading operation,
connections, hoses and fittings should be checked to maker sure they are in good working
condition. Unloading areas should be well illuminated if material transfer occurs at night.
• Drip pans - Drip pans or buckets should be used to catch small volume leakage from transfer
hoses or fittings during transfer operations. Captured materials should be reused or properly
disposed.
• Overfill prevention - During a delivery, tank truck operators should be instructed to remain with
the vehicle along with at least one qualified facility employee. Before a delivery, the liquid
level in the receiving tank is checked. Employee training procedures include instructing
operators not to leave the delivery area prior to checking and disconnecting the transfer line_
Prior to material transfer, qualified facility personnel and the driver are instructed to:
Predetermine the maximum volume of material that can be transferred without overfilling
the tank.
e Check the liquid level in the tank(s) during transfer to avoid overfilling the tank.
12.3 ABOVEGROUND STORAGE TANKS
The following practices should be implemented for aboveground storage tanks:
• All pipes leading to and from aboveground storage tank(s) that enter the tank(s) below liquid
level are equipped with valves sufficiently close to the tank(s) so as to prevent the contents of
a tank from escaping the confines of the secondary containment area in the event of a pipe
rupture outside of the containment area. Any valves that permit the direct outward flow of
tank contents are kept in the closed position when in non -operating or standby status.

• in heavy traffic areas, protective guards should be placed around tanks and piping to prevent
vehicle or forkifft damage.
• Tanks, associated valves and piping should be clearly labeled to reduce human error.
• Tanks and associated piping should be routinely inspected for integrity.
1.2.4 FUELING STATIONS
The following practices should be implemented at fueling stations:
• Avoid togging off - To minimize overfilling of truck fuel tanks, special fill procedures must be
followed to ensure that there is adequate room for expansion of cooler diesel fuel drawn from
underground tanks when it is placed in the truck saddle tanks and cryogenic delivery pump
engines. Hot summer weather greatly increases the potential for overflow of vehicle fuel
tanks that have been overfilled. To avoid this condition, the fuel tank should not be filled
above the neck on the fuel tank.
• Avoid unattended fillip - When refueling vehicles, the driver should hold the fuel nozzle in
hand during the entire refueling operation, even if the fuel nozzle has an automatic shutoff
device.
• Avoid hosincj down - Cleaning the fueling area with running water should be avoided because
the wash water will pick up fuel, oil and grease. Use dry clean-up methods whenever
possible. Control and clean up petroleum spills immediately.
• Keen shill kits accessible - An adequate supply of spill kit materials should be available before
fueling vehicle. Control, report and clean up petroleum spills immediately.
• Minimize storm_ water run-on - Minimize storm water run-on to the fueling area through flow
diversion around the fueling station and using roofs over the fueling area when feasible.
1.2.5 VEHICLE MAINTENANCE AND REPAID
Many vehicle and equipment maintenance operations use materials that can be harmful to the
environment. The following practices should be followed at vehicle and equipment maintenance
operations to reduce or eliminate potential sources of pollution:
• Parts washing - Clean without using liquids (e.g., scraper, wire brush) whenever possible_ Do
all liquid cleaning at a centralized station so solvents and residues stay in one area.
• Use nontoxic or low toxicity solvents - Minimize the number and volume of hazardous
materials used. Avoid chlorinated solvents. Choose cleaning agents that can be recycled.
• Control leaks and dHos - Collect leaking fluids in drip pans. Keep a drip pan under the vehicle
while unclipping hoses, unscrewing filters, or removing parts. Control leaks from wrecked or
damaged equipment that may be stored outdoors. Promptly transfer used fluids to proper
waste or recycling containers. Do not leave full drip pans lying around.
• Drain oil filters - Used oil filters disposed of in trash cans can leak oil and contaminate surface
water. Place used oil filters in a funnel over the waste oil recycling or disposal collection tank
to drain excess oil before disposal. Whenever possible, crush and recycle oil filters.

• Never oour li uid wastes into drains or onto the ground - Do not pour liquid waste to floor
drains, sinks, outdoor storm drains, or sewer connections.
• Recycle_ materials - Whenever possible, recycle degreasers, used oil and oil filters, antifreeze,
cleaning solutions, automotive batteries, hydraulic fluid and tires.
Segreaate and label wastes - Separating wastes allows easier recycling and may reduce
treatment costs. Locate waste and recycling containers in clearly marked and controlled
areas.
1.2.6 VEHICLE AND EQUIPMENT WASHING
Washing vehicles and equipment outdoors or in areas where washwater can flow onto the ground
can pollute surface or ground waters. Washwater can contain high concentrations of oil and
grease, phosphates, and suspended solids. To reduce or eliminate these potential sources of
pollution:
* Use designated cleaning areas only. Washwater is regulated as a process wastewater. It
can only be discharged to a properly permitted sanitary sewer or process sewer line.
If a permitted sewer line is not available, washwater should be collected in bermed areas or
sumps for offsite disposal.
• As an alternative, offsite commercial washing facilities can be used.
1.2.7 WASTE MANAGEMENT AREAS
Wastes spilled, leaked or lost from waste management areas may build up in soils or be carried
away by rainfall. To reduce the potential for pollution, the following practices should be
implemented:
• Minimize the amount of waste managed on -site.
• Prevent run-off and run-on from contacting waste management areas.
• Keep waste containers closed or securely covered.
1.2.8 TRANSFORMERS
The following practices should be implemented in transformer yard areas:
• Transformers should be inspected periodically for evidence of leaks.
• Leaks should be cleaned up as soon as possible.
• Adequate spill kit materials should be available to prevent a leak from reaching a waterway.
1.2.9 OILIWATER SEPARATORS
The following practices should be implemented to assure proper operation of an oil/water
separator unit:
• The level of oil captured in the unit should be routinely monitored and removed by a properly
permitted used oil vendor.
Any associated oil skimmers should be checked for proper operation.

• The wastewater effluent from the unit should be routinely observed or monitored to determine
if the unit is functioning properly.
• The unit should be periodically cleaned to remove accumulated solids on the bottom of the
unit and on any coalescing plates.
• Spills and leaks should be cleaned up as soon as possible.
• The discharge of solids and detergents to the oil/water separator should be minimized,
1.2.10 GREASE TRAPS AND GRIT CHAMBERS
The following practices should be implemented to assure proper operation of grease traps and grit
chambers,
• The levels of accumulated oil and solids should be routinely monitored and removed for
proper disposal.
• Any associated oil skimmers should be checked for proper operation.
• The wastewater effluent from the unit should be routinely observed or monitored to determine
if the unit is functioning properly.
• Spills and leaks should be cleaned up as soon as possible.
1.2.11 CHLORINE CYLINDERS
The chlorine handling practices and emergency response procedures found in the Site
Emergency Plan should be followed.
1.2.12 DRUM AND CONTAINER STORAGE AREAS
The following practices should be implemented at drum and container ("drums") storage areas:
• The contents of all drums should be properly identified by a label.
• Drums that are stored in a horizontal position must be lightly sealed to avoid seepage through
the bung. Drip pans should be placed beneath horizontal drums that have a dispensing valve
installed,
• Drums should be kept closed except when material is being added or withdrawn.
• For drums stored outdoors, drums caps should be used if accumulated rain water on the top
lip of the drum can cause contamination of the product. Outdoor drums should be stored off
of the ground to prevent bottom corrosion and possible leakage from the drum. Wooden
pallets may be used it an impervious surface is not available.
• Drums should be neatly stored with sufficient access and aisle space.
• Because empty drums often contain residual product, they should be managed according to
the practices listed above, unless they have been thoroughly cleaned.

• Leaking drums should be immediately moved to a containment area, placed in a salvage
drum, plugged, or the contents transferred into another drum. Spilled product should be
cleaned up immediately.
1.2.13 SEDIMENT AND EROSION PREVENTION
The following practices should be implemented in areas of hiah soil erosion potentiat or during
construction periods:
• Preserve existing vegetation or revegetate disturbed soil areas.
• Stabilize stream banks.
• Install interceptor dikes and swales.
• Use fabric filter fences around disturbed areas.
• Maintain storm water retention/detention ponds in good operating condition.
1.2.14 SARA 313 WATER PRIORITY CHEMICALS
Facilities subject to reporting under SARA Section 313 for water priority chemicals may be
required to implement special BMPs for storm water pollution prevention. Any applicable, special
6MPs are further described in Sections 10.5.2 through 10.5.7. They must be implemented in
areas where storm water can come in contact with SARA Section 313 water priority chemicals.
1.3 ADVANCED SITE -SPECIFIC BEST MANAGEMENT PRACTICES
Advanced site -specific BMPs are measures or practices that are implemented at specific
locations at this facility. They include such BMPs as oil/water separators or underground storage
tank leak detection monitoring. Site -specific BMPs implemented at this facility are described in
Section 8.3 and the locations where they are implemented are identified in Worksheet B2 of
Appendix B.
1.3.1 TRUCK FUELIHEATING OIL UNDERGROUND STORAGE TANK SYSTEM;USED OIL
ABOVEGROUND STORAGE TANK
The truck fuel underground storage tank system consists of two 10,000-gallon diesel fuel
underground storage tanks (USTs), submersible pumps with underground pressurized piping,
leak detection system, spill and overfill prevention devices, and an associated fuel dispensing
island. The tanks were installed in 1992. The Heating oil tank was installed in 1992 and is a 2500
gallon UST with a submersible pump with pressurized piping.
Fuel releases to groundwater or surface waters may occur through the leaking of the underground
tanks or underground piping system, or during fuel transfer at the fuel island, and possibly during
fuel vendor deliveries. The underground tank system is equipped with the following features to
prevent such leaks or spills.
• Corrosion protection
• Leak detection for tank and piping
• Spill and overfill control
• Automatic line leak flow restrictor
The ATG is a Veeder-Root TLS-350 equipped with a continuous statistical leak detection (CSLD)
tank level monitoring system. The system includes a sensing probe in the tank and a remote

monitor with printer. The system provides continuous monitoring of product level, water level, and
product temperature. Whenever the fueling system is idle, the TLS-350 collects data and
performs a statistical analysis to detect leaks as small as 0.2 gallons per hour. There is no need
to shut down the fueling system for the leak detection test. Leak tests are constantly being
performed, and test results are automatically provided every 24-hour period, or on demand from
the console printer.
The red jacket pump for the diesel oil system is equipped.with an automatic line leak detector flow
restrictor that dramatically cuts the flow through the piping when the unit senses a leak. The
double walled fiberglass piping has an interstitial leak detection monitor in the form of a piping
sensor.
To prevent surface spills and tank overfills, each tank is equipped with a catchment basin, overfill
alarm, and automatic shutoff device.
The catchment basin is an OPW 1 Spill Container with 5 gallons capacity. A manual drain in the
spill container can be used to drain spilled product back into the tank. If water is present, the spill
container will be manually bailed out.in addition to serving as a leak detection device, the Veeder-
Root TLS-350 level monitor also serves as a high level alarm. A red alarm light is remotely
mounted at the fueling island to indicate an overfill condition.
An OPW 61-SO two -stage overfill prevention valve serves as both an overfill alarm and automatic
shutoff device. The first stage alerts the transfer operator by reducing the flow rate to
approximately 2 to 5 gallons per minute through a bypass valve. The second stage will
completely cut off flow into the tank by closing the bypass valve if the level approaches a critical
overfill condition. The valve resets itself when the tank level drops below the critical level.
Any spills that occur on the concrete fueling station pad drain to the 14.50 Oil/Water Separator
where the spilled product is captured and can be removed.
The fuel dispenser is mounted on a Total Containment dispenser sump to contain any spills or
leaks from the dispenser or associated piping. It serves as a termination point for the double -
walled fiberglass piping from the submersible sump pump to the fuel dispenser.
There is a 375 gallon double wall aboveground storage tank for temporary storage of used motor
oil from the routine maintenance of the truck fleet. This tank is located outdoors al the west end
of truck garage bay. This tank was installed in 1992.
1.3.2 OILY WATER CONTROL SYSTEM
1.3.2.1 POLLUTANT SOURCES
Contaminated rainwater run-off from the foundations of the following equipment discharges to the
oil/water separator for treatment prior to discharge from the facility:
• Truck Fueling Station (See Section 8.3.1)
01.10 Main Air Compressor, Motor, Lube Oil System (600 gals.)
• 01.30 Nitrogen Make-up Compressor, Motor, Lube Oil Systern (300 gals.)
• 01.40 Nitrogen Recycle Compressor, Motor, Lube Oil System (1,200 gals.)
In addition, the wastewater from the truck wash area (1.170 square feet) is collected and
discharges to the oil/water separator. Any oil or grease picked up by the washwater would be
removed in the oil/wager separator before discharging to the sanitary sewer for off -site
treatment.

1.3.2.2 OILIWATER SEPARATOR
The oif/water separator is designed to handle 100 gallons per minute (gpm) of wastewater
flow. The oil/water separator has a maximum oil storage capacity of 2,500 gallons and witf act
as a containment device to capture accidental oil spills and/or leakage occurring at the
equipment. After oil is removed in the oil/water separator, the effluent is discharged to the
sanitary sewer.
The oii/water separator is installed underground inside a concrete vault. This vault serves as
a secondary containment device to capture any oil spill or leakage from the separator. Any
leakage from the unit is unlikely. In the event of a small leakage into the concrete vault,
sorbent materials shall be used to clean up the oil. The concrete vault should be monitored
weekly to check for any leakage of oil.
Oil will periodically be removed from the side -oil storage reservoir for proper disposal in
compliance with environmental regulations. Any small spills related to a waste oil vendor
pumping the stored oil from the oil/water separator would be cleaned up using sorbent
materials. A large spill could be prevented from reaching a storm drain through the use of oil
booms.
1.3.3 COOLING WATER TREATMENT BUILDING
A small building adjacent to the cooling tower houses a small tank and drums of.water treatment
chemicals. Floor drains which lead to the sanitary sewer should be plugged under normal
conditions. Major spills of water treatment chemicals should be recovered and reused in the
cooling tower.

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.

This site discharges to impair d waters experiencing problems with fecal coliform and impaired
biological integrity, and to waters upstream of the Haw River Arm of the Jordan Reservoir,
experiencing problems with nutrients and chlorophyll a violations (indicative of excessive
nutrient loads). A Total Maximum Daily Load (TMDL) for fecal coliform was approved in May
2002 for Little Troublesome Creek, but the Permittee was not allocated a load for stormwater
discharge and is not required to monitor for fecal coliform at this time.
If additional TMDLs are approved for this segment of Little Troublesome Creek, the Permittee
may be required to monitor for the pollutant(s) of concern in the future and submit results to the
Division of Water Quality, The Division will consider the monitoring results in determining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level of control, the Permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the permitted Stormwater Pollution Prevention
Plan.

representative outfall status and shall be performed as specified below in Table 4. 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 is performed when stormwater
discharge occurs but 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
Plan. A //

for your annual fee.) A copy of the new fee schedule is enclosed in this package.
Failure to request renewal within the time period indicated may result in a civil assessment of at least S250.00.
Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from
your facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS
143-215.1 and could result in assessments of civil penalties of up to S10,000 per day.
If you have any questions regarding the permit renewal procedures please contact Tony Evans of the Stormwater
and General Permits Unit at [phone], ext. 584.
Sincerely,
Bradley Bennett, Supervisor
