Subject: [EXTERNAL] RE: Storm Water Permit
Hi Jerrell,
Thank you for following up on this. I apologize for not updating you on the status sooner. The dates on the draft permit
were approximate. I anticipate that the effective date for the renewed permit will be delayed, perhaps until August
1. We do still need to get some analytical monitoring data for this site, as noted in Item 4 in the cover letter that went
out with the draft permit.
Also, i wanted to allow time for Bill Moore, in our Washington Regional Office, to conduct a site visit and write up any
recommendations he has for the permit.
To help expedite the renewal, please send the requested monitoring data to my attention as soon as possible. You may
continue to operate under your expired permit until the renewal becomes effective.

of,
Please let me know if you have any questions.

o Addition of second outfall as a result of the construction.
3. Receiving Waters: Neither Mill Creek nor Granny Branch are listed as impaired.
4. Threatened and Endangered Species:
o No T&E aquatic species
5. Analydcal and f or Qualitative monitoring during this past permit cycle: See data provided
in renewal application. One exceedance of pH at 0utfall 001 in 2013.
b. Rationale for monitoring_parameters:
o The Oil & Grease parameter for Vehicle Maintenance is changed to Non -Polar Oil &
Grease for consistency with other permits.
o pH monitoring is no longer required for discharges only associated with vehicle
maintenance activities.
7. Permit. Facility. and Owner Contacts u d� ates:
® Confirmed contact information with permittee and updated RIMS if necessary.
® Obtained e-mail addresses for each contact and updated BIMS.
® Confirmed in BIMS that permittee does not owe fees.
Recommendations:
Based on the documents reviewed, the application information submitted on December 5,
2013 is sufficient to issue an Individual NPDES Stormwater Permit.
Central -Office recommends reissuance of this permit with the same monitoring as the
previous cycle except for standard revisions to VMA monitoring for consistency with other
permits. The proposed draft permit reflects the most recent individual stormwater permit
template and boiler plate language, incorporating revisions that are similar to the industrial
general permits issued during 2012-13.

Hey Julie,
Regarding Avoca & Airgas draft permits.
Avoca — due to revisit sometime this fall. No issue with this one; recommend issue permit.
Airgas — site visit 06/30. Found some minors issue & discussed some modifications with on -site rep, which he agreed to
implement. Based on my site observations, TSS definitely should be included in the new permit. Explained TSS to Rob &
he is expecting to see it in their new permit. Questions, let me know.

Hi Bill,
When it rains it pours — I've got 3 staff report requests for you:
NCS000211 Weyerhaeuser NR Company
NCS000134 Avoca
NCS000043 Airgas
I'm sending you the draft permits, cover letters, renewal applications, and staff report requests for each facility in a
separate email. I thought that might make it easier for you to sort through them. Also, I've dropped a hard copy of the
staff report request in the mail to you, along with some maps that were too big to scan.
I've sent draft permits to all the permittees for their comments as well.
Thanks!

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000043
Airgas USA, LLC—Goldsboro Regional Plant
Wayne County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review
the draft carefully to ensure thorough understanding of the conditions and requirements it
contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during -
"measurable storm events" as defined in Part II, Section B. This term is different from
the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part 11,
Section A.
3. Changes have been made to two monitoring parameters, including a change to one
benchmark. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
• The Oil & Grease parameter is changed to Non -polar Oil & Grease [EPA
Method 1664 (SGT-HEM)]; the benchmark for Non -polar Oil & Grease is 15
mg/L.
• Vehicle maintenance monitoring parameters have been revised as follows:

NCS000043
Page 2 of 2
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that perform
onsite vehicle maintenance activities. If the facility begins vehicle
maintenance during the permit cycle, the requirements shall apply.
o pH monitoring is no longer required for discharges only associated with
vehicle maintenance activities.
4. As noted in your renewal application, the facility has added a new outfall (Outfall
002) as a result of the construction of a new building. Please provide a copy of
analytical monitoring data collected at Outfa11001 and 002 in 2013, 2014, and 2015,
to date. Please send this data to my attention at the address listed at the bottom
of this letter within 30 days following receipt of this letter.
5. It is our understanding that the facility has a new wet pond associated with the new
construction that was completed in 2013. In accordance with the requirements of
your permit (Part II, Section A), you must review and update your Stormwater
Pollution Prevention Plan on an annual basis. This includes creating a written record
of changes to the physical facility and the rationale for installation of new BMPs.
Please review the draft permit and submit the requested data and comments to me no later than
30 days following your receipt of the draft. Comments may be emailed to me at
iulie.ventaloroe,,ncdenr.gov or mailed to my attention at NCDENR, Land Quality Section,

4.0 BEST MANAGEMENT PRACTICES
Airgas minimizes contact of significant materials with storm water by:
1. Applying paint with brushes and rollers to avoid overspray;
2. Practicing regularly scheduled preventative maintenance on mechanical equipment, and heating and air
conditioning equipment on -site;
3. Periodically inspecting and testing fire detection and suppression equipment including smoke detectors,
fire hoses, and sprinkler systems;
4. Practicing procedures for proper handling and storage of significant materials such as acetone, acetylene,
paint and paint thinner to prevent the incidence of fire;
S. Implementing procedures for responding to spills of significant materials; and
6. Annual spill response employee training.
Existing structural and non-structural control measures at Airgas to reduce pollutants in storm water discharges
Include:
1. Secondary containment of acetone;
2. Secondary containment of heating oil;
3. Storage of paint in an enclosed structure;
4. Detention pond for erosion and sedimentation control;
5. Covered loading docks;
6. Secondary containment for drum oil storage at compressors;
7. Curbing and secondary containment around lime decant tanks;
8. Inside storage of liquid chemicals;
9. Used oil (aside from outdoor compressor oil); and
10. Gravel covered roadway and storage area
The following BMPs were selected to minimize the impacts of the potential pollutants identified and are both
technically and economically feasible:

1. All outdoor liquid chemical/oil storage shall be inspected monthly for potential or existing leaks or spills.
2. The helium radiators will be inspected for cracks, leaks, spills or any signs of potential antifreeze
discharge.
3. The shot blasting machine roof vent will be inspected periodically for particulate break through. The
drum storage area at the field service building is covered to eliminate exposure to storm water and with
secondary containment.
4. The miscellaneous outdoor equipment is not presently considered a significant pollutant source.
Therefore, eliminating storm water exposure is not economically feasible or justified. This area will be
inspected for signs of pollutants.
5.0 SIGNIFICANT CHANGES
The facility is currently undergoing construction of a new building. The facility has added a new outfall (outfall 002)
as the result of this construction. Future analytical sampling and visual inspections will include this recently
Installed outfall.

Airgas National Welders — Loxco Division
Wayne County
Dear Mr, Harris:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft very
carefully fo 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 changes:
1. pH and Oil & Grease Monitoring have been added to the analytical monitoring requirements.
2. I've made the permit name and address change information you have requested. The legal owner is listed as
"National Welders Dba Airgas National Welders, 109 Hinnant Road, Goldsboro, NC 27530." The permit contact
is listed as "Jerrell G. Cook, 5313 Old Dowd Road, Charlotte, NC 28208". Please verify that this is correct.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in fart 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, as
specified in Table 2.
4. Benchmarks for analytical monitoring have 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. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. You are required to collect all of the analytical and qualitative monitoring samples during representative storm
events as defined in Part II Section B. Qualitative monitoring is required regardless of representative outfall
status.

National Welders DBA Airgas National Welders
Permit No. NCS000043
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4, and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it only applies
to facilities that do vehicle maintenance. If the facility begins vehicle maintenance during the permitted
timeframe then the requirements shall apply.
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.
2. Additional requirements for the Stormwater Management Plan have been specified in Part I1 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater management
controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may qualify for
a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information is
provided in Part I Section A.
6. Per the requirements of the Neuse Riparian Buffer Rule, all stormwater drainage from portions of this site
that have been constructed after July 22,1997 must be discharged through a correctly designed level
spreader or another device that meets diffuse flow requirements per 15A NCAC 2B .0233. Diffuse flow
requirements are described in Chapter 8 of the North Carolina Stormwater BMP Manual, available at:
ht!p://h2o.enr.state.nc.us/su/bmR—forms.htm.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft. Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from the public
or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing,,a discharge begins again within the
next-10 hours. A &

PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, hereinafter 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 general permit. The Plan'shall include, at a minimum,
the following items:
1. 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 facility's location in relation to transportation
routes and surface waters, the, name of the receiving water(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 point(s) of discharge. The
general location map (or alternatively the site map) shall identify whether each
receiving water is impaired (on the state's 303(d) list of impaired waters) or is
located in a watershed for which a TMDL has been established, and what the
parameter(s) of concern are.
North Carolina's 303(d) List can be found here:

(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating,or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the 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

Pen -nit No. NCS000043
(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 III, Standard Conditions, Section
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. Thestormwater 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 areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondarycontainment is
required for: bulk storage of liquid.materiais; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storagemany amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of'all such tanks and stored materials and their associated secondary
containment areas shall be. maintained. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar'devices (which shall be
secured closed with a locking mechanism), and any 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 the material stored within the containment area. 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.
Part It Page 2 of 10

3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials ,
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and -signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
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 areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs.- The
program shall establish schedules of inspections, maintenance, and housekeeping
activities of stormwater control systems, as well 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 shall be recorded in writing and maintained
in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to.contaminate 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
PolIution 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 re -certification that the stormwater outfalls have been evaluated for the presence .
..- ..- . .-of non-stormwater-discharges.-Each annual update shall include -a -re-evaluation of the --

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no - .
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

Notes on National Welders:
Email:
Hello,
I had given my comments to Mr. Al for his signature and I saw it on his desk today so I
would expect that you should receive it maybe tomorrow. My final statement was that
my recommendation was to renew the permit. I made comments about the there only
being one outfall and that the time ponds were still in service. FYI - APS gave them two
weeks to finalize their plan for the ponds. At that time David May will decide what
action they are going to take, to issue a violation for not following thru with cleaning up
and abandoning the ponds (switching to a closed recycle system for the Acetylene
production) or permitting the ponds in some form. I am not sure if you are interested in
information like that when I make an inspection, but I thought that not recording all that I
ran across, could stand a chance of losing information that may be of benefit in some
way, to someone. I did not know if possible changes in the process would affect how you
proceeded with the renewal. Please let me know if I should just get to the
recommendation on future sites.
Thanks,
Thom

will decide what action they are going to take, to issue a violation for not following thru
with cleaning up and abandoning the ponds (switching to a closed recycle system for the
Acetylene production) or permitting the ponds in some form
• David May in Aquifer Protection gave them 2 weeks
• Aquifer protection gave them 2
• APS had been there a year ago and told them they needed to shut down the ponds
• If they get an unacceptable answer they will issue an NOV.
• They will be soon being taken out of service.
• They are not discharging from those ponds.
• They had 2 people at the tour — one from the Charlotte plant.
• They didn't have a reason
• They had some monitoring wells onsite or close -by.
• I asked if I should issue the permit or should I wait until APS is issued?
• Going ahead and issuing the new permit at least has new permits.
• APS will ensure that the lime pond will be taken out of service anyway.
• The reaction produces water and lime.
• The new system will still require the same monitoring so that should be good for
that as well.
• it should be here any day — Al Hodge has already sent to me.

Hi Thom,
Sorry you didn't get it before then. Yes 2-3 weeks will be fine. Is March
18th (3 weeks from today) an adequate amount of time?
I have attached the staff report (one that is signed - please sign that as
well) and the draft permit.
Thank you and please let me know if you have any questions/concerns.
Thanks,

Hello,
Mr. Al cc'ed me on his response to you and that has been my first notice of
the project. Will you forward me the staff report, draft and any other
pertinent information. The cc did not include the attachments. I am
swamped right now but if this is something you need quickly I can probably
squeeze it in in the next 2 to 3 weeks. Will that -be adequate?
Thanks,

I Hi Al and Roger,
I hope you both are well and had a good holiday. I am reviewing
the individual permit renewal for National Welder's Loxco
Division in Goldsboro - Wayne County. I have attached a PDF of
the staff report and draft permit and will also send the
original by mail to you.
This review should be pretty straightforward and easy to review.
I have added pH and Oil and Grease to their permit.
• Outfall is on the west and north side of the facility. Looks
like they have two outfalls going to different rivers.
• *Has 2 Lime ponds* (acetelyne manufacture by-products) that
are going to be closed in the near future with an overflow pit
near it. These pits are earthen, no lining and have a berm
around them I was told.
• *Only is noted to have 1 outfall but it appears there may be
another from the grass off to the SW of the site - this is where
the basic water .from the lime ponds would flow if there was any.
WaRO is requested to please check outfalls.*
• Owner should be *Airgas National Welders, Inc.*
• *A site visit is reconmended* to ensure outfalls are described
appropriately.
If you have any questions or need more time please let me know
but it seems pretty straightforward as so much is going to the
WWTP.

Q
Propene, also known as propylene, is an unsaturated organic compound having the chemical formula
C3H6. It has one double bond, and is the second simplest member of the alkene class of hydrocarbons,
and it is also second in natural abundance.
At room temperature, propene is a colourless, odourless gas, though when used as a fuel, it is mixed with
minute quantities of foul-smelling sulfurous compounds (mercaptans) so that gas leaks can be readily
detected.
Propene has a higher density and boiling point than ethylene due its greater size. It has a slightly lower
boiling point than propane and is thus more volatile. It lacks strongly polar bonds, yet the molecule has a
small dipole moment due to its reduced symmetry (its point group is Cs).
Propene has the same formula as cyclopropane but a different connectivity of atoms, making these
molecules structural isomers.
e There is not much stored outside according to Jerrell Cook. Only gas containters. Everything else is
under cover.
3. Impairment: 303(d), Basinwide Plan recommendations...
o Not on 303D list or has TMDL
o Stoney Creek —1.3 miles to the south — for impaired biological integrity. However I don't
believe it flows there. It goes to Granny Branch and Mill Creek. Neither have TMDL or are
303D listed.
4. Threatened and Endangered:
o None appear to be near site.

Revised Permit Recommendations: Analytical Monitoring:
1. Oil and grease has been added due to the trucks, compressors, tanks, and oil and grease on site.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
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,
as specified in Table 2.
4. Benchmarks for analytical monitoring have 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. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 1I Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. The permittee is responsible for all monitoring until the renewal permit is issued. - See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
S. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I. 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.
2.- Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 11 Section A.
The plan must also be updated annually to, include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges. 11
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information

Calcium carbide is produced industrially in an electric arc furnace loaded with a mixture of lime and coke at
approximately 2000 *C. This method has not changed since its invention in 1888:
CaO + 3C •-+ CaC2 + CO
A. edit Production of acetylene
The reaction of calcium carbide with water was discovered by Friedrich Wohler in 1862.
CaCZ + 2H20 —► C2H2 + Ca(OH)2
This reaction is the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium
carbide. In China, acetylene derived from calcium carbide remains a feedstock for the chemical industry, in
particular for the production of polyvinyl chloride, PVC. Locally produced acetylene is more economic than using
imported oil.2 Production of calcium carbide in China has been increasing. In 2005 output was 8.94 million tons with

capacity to produce 17 million tons.Ll In the USA, Europe and Japan consumption is generally declining.21
Production levels in the USA in 1990 were 236,000 tons pa.l1
The principal raw materials for acetylene manufacture are calcium carbonate (limestone) and coal. The calcium
carbonate is first converted into calcium oxide and the coal into coke, then the two are reacted with each other to
form calcium carbide and carbon monoxide:
CaO +X—CaCz+CO
Calcium carbide (or calcium acetylde) and water are then reacted by any of several methods to produce acetylene
and calcium hydroxide. This reaction was discovered by Friedrich Wohler in 1862.
CaC2 + 2H2O —> Ca(OH)2 + C2H2
They may be cut, crushed or pulverized and chemically altered. "Burning" (calcination) converts them into the highly caustic
material quicklime (calcium oxide, CaO) and, through subsequent addition of water, into the less caustic (but still strongly
alkaline) slaked lime or hydrated lime (calcium hydroxide, Ca(OH)2), the process of which is called slaking of lime.

Hi Al and Roger,
I hope you both are well and had a good. holiday. I am reviewing the individual pen -nit renewal for National Welder's Loxco Division in
Goldsboro - Wayne County. I have attached a PDF of the staff report and draft permit and will also send the original by mail to you.
This review should be pretty straightforward and easy to review. I have added pH and Oil and Grease to their permit.
Outfall is on the west and north side of the facility. Looks like they have two outfalls going to different rivers.
Has 2 Lime ponds (acetelyne manufacture by-products) that are going to be closed in the near future with an overflow pit near it.
These pits are earthen, no lining and have a berm around them I was told.
Only is noted to have 1 outfall but it appears there may be another from the grass off to the SW of the site - this is where the basic water
from the lime ponds would flow if there was any. WaRO is requested to please check outfalls.
Owner should be Airgas National Welders, Inc.
A site visit is recommended to ensure outfalls are described appropriately.
If you have any questions or need more time please let me know but it seems pretty straightforward as so much is going to the WWTP.
If you can please read,sgn and return this staff report to me within 30 days (February 23, 2009) that would be great.
Thanks and hope you have a great holiday!

Dear Mr. Carver:
Your facility's NPDES stormwater permit, NCS000043, expired on March 31, 2005. A request
for renewal was sent on September 20, 2004, though no subsequent renewal package was
received. Since your permit expired you have been essentially operating without a valid
stormwater permit, which constitutes a violation of NCGS 143-215.1.
A search of our billing database also showed that no annual fee was received from your facility
in 2005. Therefore, in order to get your permit into compliance you will need to remit 2005's
annual fee of $715 along with the enclosed renewal. materials. Filing the application form along
with the requested supplemental information will constitute your application for renewal of your
permit. `
Failure to request renewal by Friday, April 27, 2007 may result in a civil assessment of at least
$500.00. 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 $25,000 per day.
If you have any questions regarding the permit renewal procedures please contact Aisha Lau of
the Stormwater Permitting Unit at [phone], ext. 578.

Alan . Klimek,-P.E.
