Section 1. Facility Activities and Process:
Air Products & Chemicals, Inc. produces liquid oxygen, liquid nitrogen, and liquid argon
by compressing air from the environment. These liquid gases are sold for use in a variety
of manufacturing, construction and business trades. If there ever were a spill, the gases
would evaporate instantly and return to the air. All storage tanks have secondary
containment or are double walled. A truck maintenance garage is also onsite.
Since the last permit renewal, the facility added a HYDRA (hydrogen transfill)
operations area in the southwest section of the facility (Outfall 002). Hydrogen stored in
this area is not expected to impact stormwater, however, liquids associated with tractor
trailer operations will be used in the area (diesel fuel, hydraulic and crankcase oils, DEF
fluid, etc.). Additionally, in 2017, a LIN (liquid nitrogen) pipeline was installed to supply
LIN to the 15,000-gallon customer stations tank. Included in this are the transfer pumps,
metering equipment, cooldown system, and 3" VJ Pipeline. This installation will not
introduce any new pollutants to the facility.
A Duke Energy substation is on the property. The transformers at this substation inside
the Reidsville ASU are filled with non -PCB oil.
Outfall SW001: Drains the eastern side of the facili
Drainage area includes material handling and storage (raw material and finished product
storage), solid waste management (roll offs and bins for storage of office trash,
cardboard, wood, and metal), loading and unloading operations (raw material and fuel
unloading, finished product [hydrogen, nitrogen, oxygen, argon] loading), and
manufacturing operations (production of industrial gases, oil filled operational
equipment, build storage and transfers, cooling tower and associated chemical storage).
Page 1 of 7

Outfall SWO02: Drains the western side of the
Drainage area includes material handling and storage (raw material and finished product
storage), vehicle fueling and maintenance (truck terminal fueling station; mechanic
garage and shop), and loading and unloading operations (raw material and fuel unloading,
finished product [hydrogen, nitrogen, oxygen, argon] loading).
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES
regulations define stormwater discharge associated with industrial activity in 40 CFR
§ 122.26 (b)(14) as: "the discharge from any conveyance that is used for collecting and
conveying storm water and that is directly related to manufacturing, processing or raw
materials storage areas at an industrial plant. The term does not include discharges from
facilities or activities excluded from the NPDES program under this part 122. For the
categories of industries identified in this section, the term includes, but is not limited to,
storm water [sic] discharges from industrial plant yards; immediate access roads and rail
lines used or traveled by carriers of raw materials, manufactured products, waste
material, or byproducts used or created by the facility; material handling sites; refuse
sites; sites used for the application or disposal of process waste waters (as defined at part
401 of this chapter); sites used for the storage and maintenance of material handling
equipment; sites used for residual treatment, storage, or disposal; shipping and receiving
areas; manufacturing buildings; storage areas (including tank farms) for raw materials,
and intermediate and final products; and areas where industrial activity has taken place in
the past and significant materials remain and are exposed to storm water. For the
purposes of this paragraph, material handling activities include storage, loading and
unloading, transportation, or conveyance of any raw material, intermediate product, final
product, byproduct or waste product. The term excludes areas located on plant lands
separate from the plant's industrial activities, such as office buildings and accompanying
parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
Per a DEQ letter dated 2/22/1995 (cited again in letter dated 12/29/2005), ROS was
granted, therefore only monitoring for Outfall SW001 was required.

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities
and data was submitted for July 2010 to April 2022. Quantitative sampling included pH,
Total Nitrogen, oil and grease, and TSS.
Unlike most stormwater permits in its program, the Division is proposing a permit
structure with outfall-specific monitoring for discharges. Parameters are based on
potential pollutants in the drainage area, sampling results, and in some cases, dependent
upon future activities (e.g., ash removal through the drainage area). Below is a table of
the proposed monitoring for each outfall at the Air Products & Chemicals, Inc. site.

Stormwater Benchmarks and Tiered Response: Rather than limits, North Carolina
NPDES Stormwater permits contain benchmark concentrations. Stormwater benchmarks
are numerical action levels for stormwater monitoring. Benchmarks are not effluent
limits, and benchmark exceedances are not permit violations. Benchmarks provide
facilities a tool for assessing the significance of pollutants in stormwater discharges and
the effectiveness of best management practices (BMPs). Benchmark concentrations are
intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Page 3 of 7

Benchmark exceedances require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater BMPs in a tiered
program. The permit establishes a tiered approach to specify actions the permittee must
take in response to analytical results above benchmark concentrations. The tiered
structure of the permit provides the permittee and DEMLR wide flexibility to address
issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the
guidance of DWR. NC DWR follows established federal procedures for calculating acute
standards when developing the benchmarks. Just like the acute standards, metals
benchmarks normally reflect one half of the calculated Final Acute Value (the "1/2
FAV"). In most cases, translation into total recoverable values is based on an assumed
hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L. Acute
standards protect aquatic life from negative impacts of short-term exposure to higher
levels of chemicals where the discharge enters a waterbody. The Stormwater Permitting
Program applies this approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some
outfalls is adequate to characterize potential pollution or BMP effectiveness. For
example, one or more metals or other parameters may serve as an adequate tracer for the
presence of ash pollution during disturbance or ash removal in specific drainage areas at
this site. For parameters that do not have a stormwater benchmark, the Division may
develop a benchmark value if appropriate toxicity data become available or if rising
trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the
EPA and NC's pollution prevention approach to stormwater permitting. The Division's
maintains that implementation of Best Management Practices (BMPs) and traditional
stormwater management practices that control the source of pollutants meets the
definition of Best Available Technology (BAT) and Best Conventional Pollutant Control
Technology (BCT). The permit conditions are not numeric effluent limitations but are
Page 4 of 7

designed to be flexible requirements for implementing site -specific plans to minimize and
control pollutants in stormwater discharges associated with the industrial activity. Title
40 Code of Federal Regulations (CFR) § 122.44(k)(2) authorizes the use of BMPs in lieu
of numeric effluent limitations in NPDES permits when the agency finds numeric
effluent limitations to be infeasible. The agency may also impose BMP requirements
which are "reasonably necessary" to carry out the purposes of the Act under the authority
of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included under
the authority of both of these regulatory provisions. In essence, the pollution prevention
and BMP requirements operate as limitations on effluent discharges that reflect the
application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee
to propose an alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive
exceedances, exercise the option of contacting the DEMLR Regional Engineer as
provided below in Tier Three. The Regional Engineer may direct the response
actions on the part of the permittee as provided in Tier Three, including reduced
or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee
may propose an alternative monitoring plan for approval by the Regional
Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring
changes sooner than Tier Three (upon any four benchmark exceedances) and gives
guidance on one option to take. For example, the permittee may request that mercury
only be monitored semi-annually under the tiers, or that only parameters over the
benchmark be monitored more frequently. In this way, changes to the monitoring scheme
for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan (SWPPP) requirements to
include an annual certification that stormwater outfalls have been evaluated for
the presence of non-stormwater discharges, and if any are identified, how those
discharges are permitted or otherwise authorized.
• Requirement to submit a request for permit modification if the facility identifies
or creates any new outfalls, removes outfalls, or alters any drainage area that
changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and
consider the safety of its personnel in fulfilling sampling obligations under the
permit.
• Federal regulations require electronic submittal of all discharge monitoring
reports (DMRs). If a state does not establish a system to receive such submittals,
then permittees must submit DMRs electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls
throughout year.
Page 5 of 7

Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters
(qualitative and quantitative)
• "No discharge" clarifications made
• 'No
requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer
attached
• Benchmarks updated for parameters per guidance from DWR Standards group on
stormwater benchmarks
• Monitoring added for COD and BOD as monitoring requirements to check
pollutant potential in discharge
Section 5. Changes from draft to flnal:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility made: 4/28/2022
• Initial contact with Regional Office: 6/2/2022
• Draft sent to CO peer review: 9/15/2022 (review not completed due to program
process change)
• Draft sent to Mooresville Regional Office: 10/12/2022
• Final permit sent for supervisor signature: 12/6/2022
Section 7. Comments received on draft permit:
• Ben Kirby (WSRO PWS, via email 10/19/2022): I concur with the issuance of
this permit provided the facility is operated and maintained properly, any stated
effluent limits are met prior to discharge, and the discharge does not contravene
the designated water quality standards.
• Trisha Leib (SHEG Manager, via email 10/26/2022):
o Can you please clarify why the monitoring was increased from semi-
annually to quarterly for all parameters? Air Products' historical
performance demonstrates our ability to manage stormwater discharge to
maintain values significantly below the benchmark values per the previous
permit.
■ DEMLR response: The shift from semi-annual to quarterly
monitoring is a programmatic change. All individual industrial
stormwater permits now require quarterly monitoring for all
pollutants of concern. More frequent monitoring allows for a more
accurate characterization of the effluent and protects water quality.
Page 6 of 7

o The state had previously granted representative outfall status to the second
stormwater outfall at this site. Does that status remain in effect for this
new permit?
■ DEMLR response: Representative outfall status (ROS) resets with
each renewal cycle. If you wish to maintain current ROS, please
fill out the ROS form on our website (available at
https:Hdeq.nc.gov/media/9720/download) and submit the form as
directed. This request cannot be handled during the permit renewal
process.
o Section G-9 references Annual Administrative and Compliance
Monitoring Fees. Can you please provide more detail as to when these
fees/invoices will be issued and an estimate of the cost? Air Products
would like to build this requirement into our compliance system to ensure
it gets paid within the necessary timeframe.
■ DEMLR response: The period for NCS000030 begins on August
lst of each year and the annual fee due is $860. Invoices are mailed
out by Division staff approximately 30 days prior to the invoice
due date. Air Products & Chemicals, Inc. is currently paid up to
date on annual permit fees.
o This permit is likely to be issued in late November 2022. Can we ask the
state that any tasks subject to the monitoring period of October I —
December 31 be waived and Air Products' will start in January 2023?
Since the permit is likely to be issued close to the end of the Oct - Dec
monitoring period, it will be difficult to get everything in place in time to
meet the 31 Dec. deadline.
■ DEMLR response: Please follow all monitoring requirements in
the permit active at the time samples are collected. If samples are
taken before the new permit becomes effective, then monitoring
required in the current permit should be followed. If samples are
taken after the new permit's effective date, then monitoring
required in the newly issued permits must be followed. As of right
now, I do not anticipate the new permit's effective date to be
before January 1, 2023.

Good afternoon,
Thank you for submitting comments on the draft permit. Please see below for responses.
Can you please clarify why the monitoring was increased from semi-annually to quarterly for all parameters? Air
Products' historical performance demonstrates our ability to manage stormwater discharge to maintain values
significantly below the benchmark values per the previous permit.
The shift from semi-annual to quarterly monitoring is a programmatic change. All individual industrial stormwater
permits now require quarterly monitoring for all pollutants of concern. More frequent monitoring allows for a more
accurate characterization of the effluent and protects water quality.
The state had previously granted representative outfall status to the second stormwater outfall at this site. Does that
status remain in effect for this new permit?
Representative outfall status (ROS) resets with each renewal cycle. If you wish to maintain current ROS, please fill out
the ROS form on our website (available at https://deg.nc.gov/media/9720/download) and submit the form as directed.
This request cannot be handled during the permit renewal process.
Section G-9 references Annual Administrative and Compliance Monitoring Fees. Can you please provide more detail
as to when these fees/invoices will be issued and an estimate of the cost? Air Products would like to build this
requirement into our compliance system to ensure it gets paid within the necessary timeframe.
The period for NCS000030 begins on August 1" of each year and the annual fee due is $860. Invoices are mailed out by
Division staff approximately 30 days prior to the invoice due date. Air Products & Chemicals, Inc. is currently paid up to

This permit is likely to be issued in late November 2022. Can we ask the state that any tasks subject to the monitoring

be issued close to the end of the Oct - Dec monitoring period, it will be difficult to get everything in place in time to
meet the 31 Dec. deadline.
Please follow all monitoring requirements in the permit active at the time samples are collected. If samples are taken

RE: Draft NPDES Stormwater Permit
NPDES Permit NCS000030
Air Products & Chemicals, Inc.
Rockingham County
Dear Brianna Young:
Thank you for sending the draft of the NPDES Permit NCS000030. Air Products have the
following questions/comments regarding this draft permit:
1. Can you please clarify why the monitoring was increased from semi-annually to quarterly
for all parameters? Air Products' historical performance demonstrates our ability to
manage stormwater discharge to maintain values significantly below the benchmark values
per the previous permit.
2. The state had previously granted representative outfall status to the second stormwater
outfall at this site. Does that status remain in effect for this new permit?
3. Section G-9 references Annual Administrative and Compliance Monitoring Fees. Can you
please provide more detail as to when these fees/invoices will be issued and an estimate of
the cost? Air Products would like to build this requirement into our compliance system to
ensure it gets paid within the necessary timeframe.
4. This permit is likely to be issued in late November 2022. Can we ask the state that any
tasks subject to the monitoring period of October 1— December 31 be waived and Air
Products' will start in January 2023? Since the permit is likely to be issued close to the
end of the Oct - Dec monitoring period, it will be difficult to get everything in place in time
to meet the 31 Dec. deadline.
Sincerely,

I have no comments for this permit. I concur with the issuance of this permit provided the facility is operated and

Good afternoon,
I apologize for the additional email, I have one more question: a site map submitted with the permit application shows a
Duke Power Company substation present on the property. Is this substation still present on the site and operational? Do
you know if this substation uses PCBs or mineral oil (now and historically)?

Brianna, here is a summary of changes and list of industrial activity. The operation of the facility has not significantly
changed since the 2015 NOI submittal. The materials and activities are the same at the site. As mentioned in the
attached summary, the site added a liquid hydrogen loading/unloading station and installed a liquid nitrogen transfer
pipeline to provide nitrogen to our customer next door.
Let me know if this satisfies the remaining data and information required for your review of our application for renewal.

Brianna, a little behind on our target to supply this information within 30 days. Here is some of the information
requested for our permit renewal. We are working to complete the remainder by early next week.
• Outfall coordinates for each discharge location;
o Outfall# 001 Latitude: 36.32500 Longitude:-79.652500
o Outfall #:002 when looking on the map says the location is the exact same as outfall#: 001, outfall #2 is
about 150 feet east of outfall#1.
• Summary of industrial activity in each outfall drainage area;
o Will provide next week
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
o See attached spreadsheet
• Verification that the information in the renewal application is still complete and correct;
o Reviewed the Stormwater Permit Summary report
■ Updated the Billing party contact information
■ All other information looks correct
■ The site completed steps 1 and 2 of the eDMR Six step process in early 2021
■ Visited the Stormwater e-payment site - No outstanding fees
An explanation of any operational changes since the renewal application was submitted.
o Will provide next week
Let me know if any questions.

Good afternoon,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000030.
Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the Air Products & Chemicals, Inc.
(NCS000030). I need additional information in order to 1) confirm that the information I have is correct and 2)
make sure the permit adequately serves the needs of the facility. Please provide the following:
• Outfall coordinates for each discharge location;
• Summary of industrial activity in each outfall drainage area;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
o The permit billing party has been updated
o All other information looks correct
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s) for the
facility. Please review the facility information to make sure it is correct. Information can be updated using the links
provided below, where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact

• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form

• Facility address only: Email Bethany og ulias
• Stormwater outfall information: Email Bethany Georgoulias

Visit the eDMR Six Steps website and complete Steps 1 and 2.
Pay outstanding permit fees: Stormwater ePayment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

Brianna, here is a summary of changes and list of industrial activity. The operation of the facility has not significantly
changed since the 2015 NOI submittal. The materials and activities are the same at the site. As mentioned in the
attached summary, the site added a liquid hydrogen loading/unloading station and installed a liquid nitrogen transfer
pipeline to provide nitrogen to our customer next door.
Let me know if this satisfies the remaining data and information required for your review of our application for renewal.

Changes in Industrial Activities
From the 2015 renewal application:
This change was implemented and is in operation. This activity occurs in the outfa11OO2
drainage area.
The facility is in the process of adding a HYDRA (Hydrogen transfill) OPERATIONS AREA. It is anticipated
that the operations will commence early spring 2015. The area includes an approximate 42' x 75' (3150
ft2) area for tube trailer staging area; an 8'x10' (80 ft2) shed ; a 10'x 62' (620 ft2) loading bay; and a 10'
x 36' (360 ft2) work area. Total area =4210 ft2
The area will be located in the southwest corner of the facility. Hazardous Materials and quantities
stored in the area will be: a) 3 tube trailers of Hydrogen.
Various liquids associated with tractor trailer operations will be used in the area (diesel fuel, hydraulic
and crankcase oils, DEF fluid etc) in quantities commonly used in the vehicles while operational. No
storage of materials supporting tractor trailer operations is anticipated in this area.
The facility currently has a truck maintenance garage and has procedures and policies in place to handle
emergencies and minor spills of oils etc. Hydrogen is a gas at ambient temperatures and will not impact
stormwater.
For the updates to the renewal application:
This change was implemented in 2017.
A LIN ( liquid nitrogen) pipeline was installed to supply LIN to the customer stations tank that supplies
Keystone Foods. Keystone is adjacent (west boundary)to the Reidsville facility. The transfer line is — 500
ft in length. The LIN pipeline will transfer LIN from the 16.20 LIN flat bottom storage tank to the 15,000
gallon customer stations tank. The customer station tank sits at the property line between Air Products
Reidsville facility and Keystone. The equipment installed was the transfer line from the outlet of the
16.20 flat bottom LIN tank to the valve at the fill point of the customer stations tank. Included in this are
the transfer pumps (including installed spare), metering equipment, cooldown system, and the 3" VJ
Pipeline. The transfer process will be fully automated and will not require operator assistance under
normal circumstances.
This installation will not introduce any new pollutants to the facility. The pipeline spans from the east
side of the facility to the west boundary where our customer Keystone is located next door.

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 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
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.)
Inspection and testing of facility equipment and systems to uncover conditions that could —9ttP
cause breakdowns or failures resulting in discharges of pollutants to surface water and

Changes in Industrial Activities
The facility is in the process of adding a HYDRA (Hydrogen transfill) OPERATIONS AREA. It is anticipated
that the operations will commence early spring 2015. The area includes an approximate 42' x 75' (3150
ft2) area for tube trailer staging area; an 8'x10' (80 ft2) shed ; a 10'x 62' (620 ft2) dock; and a 10' x 36'
(360 ft2) work area. Total area =4210 ft2
The area will be located in the southwest corner of the facility. Hazardous Materials and quantities
stored in the area will be: a) 3 tube trailers of Hydrogen.
Various liquids associated with tractor trailer operations will be used in the area (diesel fuel, hydraulic
and crankcase oils, DEF fluid etc) in quantities commonly used in the vehicles while operational. No
storage of materials supporting tractor trailer operations is anticipated in this area.
The facility currently has a truck maintenance garage and has procedures and policies in place to handle
emergencies and minor spills of oils etc. Hydrogen is a gas at ambient temperatures and will not impact
stormwater.

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 1310 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"

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 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 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.
• 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 fillers,
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, offeite 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 filler 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 Monitorina 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.

Spill Prevention Control and Countermeasure Plan
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 Systom
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.)
• 1CP-K301/321 Recycle/Make-up LOS (565 gals.)
• 1CS-T361 Compander (250 gals)
• 01.16F Main Air Compressor (300 gals)
• 01.30F Recycle (300 gals)
• 01.46F Recycle (1,000 gals)
• 01.14A Compander (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 oil/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 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

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.
*** BMP must include discussion on integrity testing (i.e. explain why monthly visual inspection
are sufficient) and if any additional secondary containment provisions must be implemented.
8.3.5.2 OIL DRUMS
Oil containers are of carbon steel construction. The tight -head unlined drums meet UN
packaging standards (UN 1A1/Y1.8/300) 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.
