Releases: See "Henderson TRI RY2015 Calculations.xls" file for the assumptions and calculations
related to releases of cobalt.
Conclusion: The facility only processed cobalt at levels above the reporting thresholds in RY2015;
thus TRI reporting is required for this chemical. The annual reportable amount for cobalt is greater
than 500 lbslyear, so cobalt must be reported on the TRI Form R.
AECOM appreciates the opportunity to support the Henderson facility. Please do not hesitate to
contact me or Peter Kroll at [phone] if we can be of further assistance,

RE: Draft Stormwater Permit, NCS000171
Hi Robert,
Hope you are well. -Thanks for your questions. My answers below:
1. How can we determine that the rain falling from the clouds does not exceed the Benchmark discharge characteristics?
Has this ever been an issue in the past?
We've had this question regarding pH, but not any of the other parameters Kennametal has been asked to test
for, to my knowledge. Is pH what you are referring to? We have told permittees in the -past that if they are concerned
that the native rain is causing a SW benchmark exceedence in of itself, then to show that by testing and we would
consider that and incorporate that into the response.
2. 1 understand that we can petition for representative outfall status at some point after initial sampling and analysis.
The Regional Office indicated to me that the Representative sampling outfalls you had were appropriate. If they confirm
that, you do not need to request that again. Cheng -- can you please comment on that?
Can we also petition for annual sampling rather than semi-annual sampling?
Yes, with an individual permit you can petition for reduced sampling. if your sampling results consistently show your
samples are well below benchmark values we would gladly review a modification to your permit.
I have some idea of the costs associated with these sampling events (very expensive) and given the shaky economic
situation in NC we must all look for ways to conduct our business in a responsible manner but while holding costs to a
bare minimum.
I've pasted a quote (below) we received from Prism Labs a couple'of years'ago. While the pricing may have changed a
bit, we find these prices are pretty standard throughout NC. pH can be done onsite if you have a trained technician or
you yourself were able to do it, and samples can be taken by someone at your facility and sent to the lab or taken by the
lab or taken by a consultant. It appears from the prices below that the testing itself should be about $200-$300, every
six months.
These tests are very standard for industrial facilities with general and individual permits, as is the semi-annual testing
schedule. We have included these stormwater pollution prevention plan requirements for all individual and general
stormwater permits (about 3,000 permits) in North Carolina and in fact Kennametal's permit is oneof the last to have
made this change. If Kennametal needs to hire a consultant to. create a SPPP plan there are likely to be many qualified
companies and consultants in NC that would be able to bid on this work as there have been so many permittees that
have had this requirement. The Regional Office may be able.to tell you of some consultants who's work they have seen.
Please give me a tail if you have any further questions or comments —1'd be happy to answer them.
Thank you,
Jennifer Jones

Dear Permittee:
Division of Water Quality

August 3, 2009
Dee Freeman
Secretary
Subject: NPDES Stormwater Permit Coverage Renewal
Parkdale Mills Incorporated -Pit 8
COC Number NCG170340
Gaston County
In response to your renewal application for continued coverage under stormwater General Permit NCG170000 the Division of
Water Quality (DWQ) is forwarding herewith the reissued stormwater General Permit. This permit is reissued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007 (or as subsequently amended.)
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Permit NCG170000
• A copy of a Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all the
changes in the reissued permit.
The more significant changes in the General Permit since the your last Certificate of Coverage include the following:
• Permit cover page — Coverage is expanded to include industrial activities similar to the categorically identified industries.
• Part I Section A — This part explains that the No Exposure Exclusion from permitting option may be available to the permittee.
• Part II Section A — Several minor expansions and clarifications of the required content of the Stormwater Pollution Prevention
Plan have been added. Please be sure that your plan is updated to comply with the new requirements.
• Part II Section B — Qualitative monitoring must now be conducted during a representative storm event.
• Part II Section B —The permittee is required to keep a written record of his response to problems identified by his qualitative
monitoring observations.
• Part II Section C - For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month, new
provisions require that discharges from the vehicle maintenance areas be sampled twice per year, and that the sampling
results be compared to new numerical benchmark values. (The previous cutoff concentrations have been eliminated.)
• Part 11 Section C -- For facilities,with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require the permittee to execute Tier One and Tier Two response actions, based on the first benchmark
exceedence (Tier One) and the second consecutive benchmark exceedence (Tier Two). Tier Two requires that the permittee
institute monthly monitoring instead of twice -per -year monitoring, until three consecutive monitoring events show no
benchmark exceedences,
• Part II Section C — This part contains a new provision that four exceedences of any particular benchmark will trigger increased
DWQ involvement in the permittee's stormwater management and control actions. DWQ may direct the permittee to apply for
an individual permit, or may direct the implementation or installation of specific stormwater control measures.

Hi Jennifer,
I have been reading over the draft permit that was received on March 24th and have forwarded the draft to our corporate
office for their review as well.
At this point the questions that I have are:
1. How can we determine that the rain falling from the clouds does not exceed the Benchmark discharge characteristics?
Has this ever been an issue in the past?
2. 1 understand that we can petition for representative outfall status at some point after initial sampling and analysis. Can
we also petition for annual sampling rather than semi-annual sampling? I have some idea of the costs associated with

these sampling events (very expensive) and given the shaky economic situation in NC we must all look for ways to
conduct our business in a responsible manner but while holding costs to a bare minimum.
In my preliminary reading of the draft, it is also obvious that we will likely need to contract an engineering firm to satisfy
the additional requirements for the site maps, site plan, stormwater management plan and stormwater pollution prevention
plan.
Since we have strived for compliance and our data has shown good results, I guess I need help justifying the potential
expenditure of •>$10,000 in the first year of the new permit compared to <$1,000 for the last 5 years under the pending
permit renewal. In looking solely at the increased costs ( and this is exactly what most upper level management looks at,)
'one would think that we have been remiss in our stormwater requirements.

Robert

Dear Mr. McGhee:
Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
AnaIyttical monitoring changes:
1. Analytical monitoring parameters have been added to this permit.
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 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 outfaU 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.
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. Monitoring for TPH has replaced Oil & Grease. 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 II Section A.
More details regarding secondary containment are provided. 1
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. s
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 Tar -Pamlico Riparian Buffer Rule, all stormwater drainage from portions of
this site that have been constructed after January 1, 2000 must be discharged through a correctly designed
level spreader or another device that meets diffuse flow requirements per 15A NCAC 2B .0261. Diffuse
flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP Manual, available
at: http://portal.ncdenr.org/web/wq/ws/su/bmp-manual.
7. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Annual Summary
DMR copy must be submitted to the local DWQ Regional Office by March 1 of each year.
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.

SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which maybe expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map o� r 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 miap) 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.
(b) A narrative description of;storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal. practice`s. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate

2. Stormwaier Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In 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. Secondary containment is
required for: bulk storage of liquid maierials;,storage in any amount of Section
313 of Title III of the Superfund Amendments.and Reauthorization Act {SARA}
water priority chemicals; and storag in anyamount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanksd stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves -or other similar devices (which shall be secured
closed with a locking mechanism), and any stormwater that accumulates in the
containment area shall bye at a minimum visually observed for color,foam outfall
staining, vis&e`sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
.Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
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
Part II Page 4 of 10

Permit No. NCS000171
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 prevcntative
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 ecorded in writing and maintained
in the SPPP. // )n %
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 Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. • Within 30 days of such notice, the permittee shall
submit a time schedule, to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part II Page 5 of 10

Permit No. NCS000171
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.

part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part li B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall.include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, including'the log•of the sampling data and
of actions taken to implement BMPs associated witt t in activities, including

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

From Summary of BMPs (2004): Loading and unloading takes place via covered'docks. Plant is small quantity
generator of haz waste. Each floor drain inside milling room has sedimentation 'sump to separate powders
from wash water, then through more separation to city sewer line. No drainage water is discharged to
stormwater conveyances. Some empty drums and pallets are stored outside, and may be exposed to SW,
however drums are closed or positioned to preclude collection of SW. Collected metal powders from sumps
are stored in drums with lids to prevent exposure; they are dried in an enclosed steam heated oven located
outside. Drums of water treatment chemicals are on pads inside the building. Monthly visual inspections of
outfalls, them. Storage areas & other areas of concern is conducted by EHS admin. Outside bulk storage tanks
are enclosed inside concrete dike. Accumulated SW is removed after it is inspected and determined that no
sheen is present.

• 1999 there was an addition to the warehouse and powder milling departments
• November 1999 -- installation and start-up of the solvent recycling system.
From 1999-2004 there haven't been any changes to industrial activity.
3. Impairment:
Site is located in the Tar -Pam River basin nutrient sensitive waters (N&P).
In NC there is a statewide mercury TMDL.
There are no other TMDLs for the receiving waters and they are not on the 303D list.
4. Threatened and_Endangered:
o There are no threatened or endangered species in the area according to the NCDENR's Natural
Heritage Program.
5. Location:
o Location drains to z receiving waters, UTs to Joes Branch and Martin Creek. Both are in the Tar -
Pam River basin.
6. Iridustrial Changes Sin ce_Prev_ious_Permit:
o None from 1999-2004.
7. Analytical-Monitoring_Notes:
Sent in test information from 2003. Indicates that the previous permit stated that there was an indication to
monitor in the last year of the permit. Permittee tested for BOD, COD, TKN, NO2N, NO3 N, TP, TSS and pH., All
tests for parameters were below current benchmarks. Previous staff member wrote a draft permit and
included parameters for BOD, COD, Halogenated Hydrocarbons (1,1,1-Tricholroethane), Cobalt, TSS, and pH.
No indication in file as to why Halogenated Hydrocarbons (i,i,i-Tricholroethane), and Cobalt were added — only
indication is that file states they are added based on information and sample data. There is no other data in

Discussions with permittee: 2/3/m Robert McGhee, 252-492-4163 x303
1. Q. Please describe your manufacturing process?
ANSWER: We manufacture tungsten carbide powder. We receive an intermediate material,
process to make tungsten metal, and then add carbon black to make a tungsten carbide. That is
sent to other facilities where they bake it on to make blades etc. We do not make blades.
2. Q. Have you been doing analytical sampling since the last permit?
a. ANSWER: Not since the last year of the permit because in that permit it stated that the only
monitoring that had to be done was in the last year of the permit
3. Have you had any industrial changes since 2004?
a. He can't think of any off the top of his head. He will let me know if there is anything.
4. Q. In your BMP summary you stated that: "Some empty drums and pallets are stored outside, and may be
exposed to SW, however drums are closed or positioned to preclude collection of SW". Please describe if this
is still happening and if so, how.
a. Process still the same. Not noticed any issues or problems with that. When he does the monthly
report he would note it to the report and send it immediately to the responsible parties.
5. In your BMP summary you stated that you had "Monthly visual inspections of outfalls & chemical areas". Is
this still happening?
a. Yes. Sends out report to any problem areas and they are'to clean it up immediately.
6. In your BM P summary you stated that you had "collected metal powders from sumps are stored in drums with
lids to prevent exposure; they are dried in an enclosed steam heated oven located outside." Is that still
happening? Can you describe that process more? Is there any runoff from the oven are or around the oven?
a. Yes. Powder is very expensive and they need to reuse it. It happens just as described above.
7. Because your site is located in the Tar Pam Basin we are concerned about N & P. Do you have any chemicals
that have N or P in them?
a. - No.
8. Do you have a lot of paints or dyes on site for your process?
a. No
9. Do you have a lot of cobalt on site?
a. Cobalt is a metal powered and that binds the tungsten together. Yes it is in powered form.
10. What about the Halogenated hydrocarbons?
a. Halogenated hydrocarbons — solvent used on site and in process. Mostly in the form of Heptanes.
When they mill the powderthey use iot to suspend the mix heterogeneously. They reuse the solvent
because it is expensive. All of that process is done in the building. Solvent is stored outside in 2 above
ground double- walled tanks and have a cement dyke around them.
ii. What would happen if the tanks burst?
Page 7 of 11

NCS000171
a. If the inside one burst, there is -an alarm. If both are ruptured the cement dyke around the tank will
hold 15,000 gal (tank is io,000 gal). Have pneumatic tanks and would put it in a tank and put it in
distillation and reuse it because it is expensive.
12. What other metals and powders are stored onsite?
a. Tungsten carbide, Titanium, Cobalt, Niobium carbide, Tantalum carbide, Chromium carbide, and Nickel
carbide.
b. They are stored in the warehouse. They are transported to the facility by tractor -trailer. Loading/un-
loading dock is covered and loading is in the building.
c. Site says there is no potential for stormwater exposure.
d. If spilled, if touching the ground, it would go to the recycle system, if it is, not touching the ground it
would go into the process.
13. Have you had any significant spills of any type?
a. No.
14. What is your SIC code?
a. 3399
15. Do you have any other permits?
a. Air permit (NC), wastewater discharge permit (local permit with the city of Henderson), small quantity
generator of haz. waste (contract with a company to take away waste).
16. What monitoring have you done since the last renewal of your permit?
a. Have done the analytical monitoring in the last year of the permit and since then have done semi-
annual qualitative monitoring and monthly inspection of all the outfalls.
17. Why are you monitoring only outfalls 2 and 4?
a. They requested.representative outfall status. He has a letter and will send me a copy.
18. 1 was looking at your TRI and saw that you had releases of ammonia and formaldehyde on there. What are
those for, where are they used, -how are they stored on site and would it be possible for them to get into
stormwater?
a. We began dissociating ammonia to get hydrogen for our furnaces as a result of hurricane Katrina
and its effect on the plant that makes liquid hydrogen for us (and NASA). The ammonia is cracked
into hydrogen gas and nitrogen gas which we use as an atmosphere in our carburizing furnaces.
With electric heating elements in this atmosphere we are able to achieve the high temperatures
(2800 F) for the carbon to bind with the tungsten to make tungsten carbide. Anyway the releases
of ammonia (io lbs to air) is an good engineering estimate from typical transfer operations of
loading our tank from a tank truck. For TRI purposes I used the range code of 1- io lbs. and then
put the actual number as io for worse -case scenario. The releases were likely on the lower side of
this range.
Now, after having said all of that, we are removing this ammonia and tank from our site this
month. We now have an alternate means (up north) of acquiring liquid hydrogen in the event that
the Louisiana plant gets under water again.
The formaldehyde is the by-product of combustion of natural gas in our gas fired boilers which are
used for process heating. 1 believe this amounted to o.00185 lb. of emissions to the air last year and
Page 8 of 1 i

NCS000171
0.7o875 lb. the year before.
No stormwater issues with either of these.
19. Do you have ROS?
a. Yes. Required to monitoring only #z and #4. [See letter in permit file].
20. What form is the formaldehyde that is produced (i.e. gas or liquid), if it is in a liquid form is it stored on site,
and where and how is it disposed of?
a. The formaldehyde that is results from the combustion of natural gas in our boilers is in gas form
and is an air emission. This is reported each year in our emissions inventory to the DAQ.
21. Can you describe where the powders used in your process are stored or located on your site? At any time
are they located or their products located outside (i.e. waste products and if so, where).
a. We occasionally have some drums of secondary material in que [sic] for the dryer oven (back of
main building). These are either covered or have tight fitting lids on the containers or both. All of
the other powders are stored under roof(s). The materials that are involved in the transfer
operations from the metal storage buildings to the main building are in metal drums with tight
fitting lids.
Revised Permit Recommendations: Analytical Monitoring:
1. Adding Cobalt, Nickel, Chromium, pH, and TN. Removing TKN, NO2-HO3-N and TP.
z. All analytical monitoring has been set to semi-annually during a representative storm event as defined in.
Part II Section B..The permittee must also document the total precipitation for each event. if no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow"
within 3o days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 6o days apart, as specified in Table z.
3. 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 z 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.
4. The permittee is 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.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables
1, 4, and 5.
6. The flow reporting requirement has been removed per DWq revised strategy. (The total rainfall parameter
is in this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Page 9 of I

NCS000171
Other Proposed Changes to the Previous Permit:
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 11 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.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part 11 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.

PART 11 MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part ill, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map orappropriately drafted
AF
equivalent map), showing the facility's location to 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'amunicipal 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) Gst of;impaired waters) or is located in a
watershed for wh`ch�a TMDL !has, been established, and what the parameter(s)
of concern are.
(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
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
Part 11 Page 3 of 10

Permit No. NCS000171
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan,shaall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirementsi and. Records. Secondary containment is
required for: bulls storage of liquid matZrials;,storage in any amount of Section
313 of Title III of the Superfund Amendment's and Reauthorization Act (SARA)
water priority chemicals; and storage,in any/amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks`nd/stored materials and their associated secondary
containment areas shall lie"'maintained. If the secondary containment devices are
connected to storr�nwater 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 tie at a minimum visually observed for color, foam, outfall
staining, visiblesheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall -be released'if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
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
Part II_ Page 4 of 10

Permit No. NCS0o0171
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 corripliarice with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
_ in the SPPP. �
5. Employee Training. Training programs ishall be developed and training provided at a
minimum on an annual basis for facilitypersonnel with responsibilities for: spill response
and cleanup, preventative maintenance.activities, and for any of the facility's operations
that have the potential to contaminate•stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to. the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 11 Page 5 of 10

'4• Permit No. NC5000171
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made:
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part ll B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, including,t.he log -of the sampling data and
of actions taken to implement BMPs associated withlthe,industrial activities, including
vehicle maintenance activities. Such documentation shall`be kept on -site for a period of
five years and made available to the Director or the Director's authorized representative
immediately upon request. /'�{'` �.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative ,storm event is a storm event that measures greater than 0.1 inches of rainfall. The time between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

Dear Mr. Brainard:. 3 ti
Your request to sample the storrnwater discharge outfalls on the above referenced site for purposes
of NPDES stormwater permit monitoring requirements has been reviewed by Steve Ulmer of .the Water. J, `
Quality Section staff. Your request described six outfalls that discharged stormwater from the facility's
industrial areas
According Io`Ithe site maps that accom •anied our letters of request, outfalls #2 46 #4 and 45 are 1

Based upon your discussions with Steve Ulmer, the'storrnwater discharges from outfaIls # 2 and
#4 shall be,considered representative outfaus for stop 'water analytical monitoring. As mentioned in your't JI„
letter dated April 22, 1995,'continued progress in "'plugging" indoor floor drains that lead to these outfalls
is required. Elimination of the indoor floor drain connections to the storm sewers shall be completed by
November 1, 1995.:, .v
Visual observation shall be required at outfall M. If deemed necessary, analytical monitoring at
outfall #3 may be required in the future. The requested determination is warranted and in accordance with
Chapter 40 of the Code of Federal Regulation'part 122.21(g) (7). -We authorize you to sample at outfalls"
#2 and #4 as stormwater discharges representative of the runoff from the Kennametal, Inc., facility for

SUMMARY OF BEST MANAGEMENT PRACTICES
Efforts to minimize exposure to stormwater include the following best
management practices:
• Loading and unloading of materials and products to and from trucks takes place
directly into the building via covered docks.
• The plant is a small quantity generator of hazardous waste. Full drums of waste
are not stored on site. As soon as they are full they are taken off site by a licensed
transporter. There is no extented storage of hazardous wastes on site other than
satellite accumulation at the point of generation.
• Each of the floor drains inside the milling rooms has a sedimentation sump to
separate powders from wash water. Drainage then travels to the main sump for
/ additional opportunity for sedimentation, before it passes through the
✓ solvent/sludge separator, and on to the city sewer line. No drainage water is
discharged to stormwater conveyances from these areas.
LSome empty drums and used pallets are stored outside where they may be
exposed to stormwater. However, these drums are closed or are positioned to
preclude the collection of stormwater.
• Collected metal powders from the sumps are stored in drums with lids to
prevent exposure. These powders are dried in an enclosed steam heated oven
located outside.
• Drums of recirculating water treatment chemicals are placed on spill
containment pallets tin de_tle building.
• A monthly visual inspection of the, facility-outfalls, chemical-storage- areas,.and
other areas of concern is conducted by the EHS Administrator or his designate.
• Outside bulk solvent storage tanks are double steel wall tanks and are enclosed
inside a concrete dike. Accumulated stormwater is removed after it is inspected
and determined that no sheen is present.
• Secondary containment is present in the metal storage building in the location
where liquid chemicals are stored. This storage includes containers of kerosene
and various oils all of which are in 55 drums or smaller. The secondary
containment will hold approximately 300-500 gallons. A large spill containment
kit and overpack drum is located in this bay of the metal storage room.
Ethomeen (a mild corrosive) used in the manufacturing process (typically 4
drums or less) is stored in a separate bay of the metal storage room. These
drums are stored on a still containment pallet.

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES
The stormwater pollution prevention plan has been amended whenever there
was a change in the design, construction, operation or maintenance of chemical
storage systems, stormwater controls or conveyances, or production processes
affecting stormwater. The plan is also reviewed annually and updated if necessary.
The plan was developed and implemented in May 1995. Since that time the
plan has had four updates. The first update occurred in June of 1997 and was the
result of implementation of BMPs that were part of the development of the initial
plan. The second update occurred in March of 1998. This update was the result of
the annual review of the plan which showed that some personnel changes had
occurred and the address of the plant had been changed for emergence response
purposes. The third update occurred in March of 1999 and was the result of an
addition to the warehouse and powder milling departments. The fourth update
occurred in November of 1999 and was the result of the installation and start-up of
the solvent recycling system.
No significant changes in industrial activities have occurred recently. The
plan has been reviewed on three occasions since 1999. Only administrative and non-
significant changes to the plan were implemented.

During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. This Plan shall be considered public information in accordance with Part II, Standard
Conditions, Section E.8. of this permit. The Plan shall include, at a minimum, the following
items:
a. 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:
(1) 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.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area, building locations and impervious surfaces,
and the percentage of each drainage area that is impervious. For each outfall, a
narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill

prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. 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 with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. 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.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of
potential of sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
c . Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory

authorized representative immediately upon request.
2. Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
Page 6

l' 0611213.Y0=1411
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
c. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part H,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:.
(1) All other discharges that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and,wetlands.
(3) Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a
non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
8. VehicIe maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPH has replaced Oil & Grease. 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 H 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 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 Tar -Pamlico Riparian Buffer Rule, all stormwater drainage from portions of
this site that have been constructed after January 1, 2000 must be discharged through a correctly designed
level spreader or another device that meets diffuse flow requirements per 15A NCAC 2B .0261. Diffuse
flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP Manual, available
at: http://portal.ncdenr.org/web/wq/ws/su/bmp-manual. ,
7. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Annual Summary

Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters have been added to this permit.
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 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. � 2
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.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.

Permit No. NCS000171
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas whe a elimination of exposure is
not practical, the stormwater management pljWI document the feasibility of
diverting the stormwater runoff away f a 'as pote tial contamination.
(b) Secondary Containment Requirement ecor Secondary containment is
required for: bulk storage of liquid m e `-1 torage in any amount of Section
313 of Title III of the Superfund en a nd Reauthorization Act (SARA)
water priority chemicals; and st g yfamount of hazardous substances, in
order to prevent leaks and sp' I fr c aminating stormwater runoff. A table
or summary of all such to an o materials and their associated secondary
containment are s 11 a in d. If the secondary containment devices are
connected to stor a c v . ce systems, the connection shall be controlled
by manually activ s other similar devices (which shall be secured
closed with a I ing m nism), and any stormwater that accumulates in the
containment a shall at a minimum visually observed for color, foam, outfall
staining, visi le and dry weather flow, prior to release of the accumulated
stormwater. ulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMA) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
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
Part I Page 4 of 10

Permit No. NCS000171
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 Ix
g st uctural BMPs. The
program shall establish schedules of inspections, ma' nce, and housekeeping
activities of stormwater control systems, as we s ` -1 equi ment, facility areas, and
facility systems that present a potential for st w r or stormwater pollution.
Inspection of material handling areas and reg caning Y edules of these areas shall
be incorporated into the program. Timely coH with the established schedules for
inspections, maintenance, and housekeepi s ll° corded in writing and maintained
in the SPPP.
Employee Training. Training p&enctivities,
l�ia a developed and training provided at a
minimum on an annual fo onnel with responsibilities for: spill response
and cleanup, preventative at and for any of the facility's operations
that have the potential to rmwater runoff. Facility personnel (or team)
responsible for implerg, ting t ining shall be identified, and their annual training
shall be documented, the si ture of each employee trained.
6. Responsible Party. TWSWrmwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 11 Page 5 of 10

Permit No. NCS000171
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. mplementation of the Plan
shall include documentation of all monitoring, meas nts, inspections, maintenance
activities, and training provided to employeesSan

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a dischame be: -ins within 10 hours.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the Plan. This Plan
shall be considered public information in accordance with Part III, Standard Conditions, Section E, Paragraph 3 of
this individual permit. The Plan shall include, at a minimum, the following items:
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.
(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.
(c) A site map drawn to scale with the distance legend indicating location of industrial activities
(including storage of materials, disposal areas, process areas and loading and unloading areas),
drainage structures, drainage areas for each outfall and activities occurring in the drainage area,
building locations, existing BMPs and impervious surfaces, and the percentage of each drainage
area that is impervious. For each outfall, a narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3
previous years and any corrective actions taken to mitigate spill impacts.
(e) , Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the requirements found
in Part III, Standard Conditions, Section B, Paragraph 3.
Stormwater Management Plan. The stormwater management plan shall contain a narrative description of
the materials management practices employed which control or minimize the exposure of significant
materials to stormwater, including structural and nonstructural measures. The stormwater management
plan, at a minimum, shall incorporate the following:
(a) Feasibility Study. -A review of the technical acid economic feasibiliry•`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 Schedule. A schedule to provide secondary containment for bulk storage
of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals,, or storage.of.hazardous substances to
.-prevent leaks and spills from contaminating stormwater runoff.-4f the secondary containment
devices are connected directly to"stormwater conveyance systems, the connection shall be
Part lI Page I of 5 _

Permit Number NCS000171
controlled by manually activated valves or other similar devices [which shall be secured 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 narrative description shall be provided of Best Management Practices (BMPs)
to be considered such as, but not limited to, oil and grease separation, debris control, vegetative
filter strips, infiltration and stormwater detention or retention, where necessary. The need for
structural BMPs shall be based on the assessment of potential of sources to contribute significant
quantities of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an
assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel
(or team) responsible for implementing the SPRP shall be identified. A responsible person shall be on -site
at all times during facility operations that have the potential to contaminate stormwater runoff through spills
or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific.
Therefore, a SPCC plan may be a component of the SPRP, but may not be sufficient to completely address
the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be .
incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance program shall be
developed. The program shall document schedules of inspections and maintenance activities of stormwater
control systems, plant equipment and systems. Inspection of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training provided at a minimum on an
annual basis' on proper spill response and cleanup procedures and preventative maintenance activities for all
personnel involved in 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.
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.
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. The Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis.
The Director may notify the permittee when the Plan does not meet one or more of the minimum
requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the
Director for modifying the Plan to meet minimum requirements. The permittee shall provide certification in
writing (in accordance with Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the
changes have been made.

Subject. Request for Identical Outfall Exemption
NCS000171
KennameW, Inc.
Vance County
Dear Mr. Brainard:
Your request to sample the stormwater discharge outfalls on the above referenced site for purposes
of NPDES stormwater permit monitoring requirements has been reviewed by Steve Ulmer of the Water
Quality Section staff. Your request described six outfalls that discharged stormwater from the facility's
industrial areas.
According to the site maps that accompanied your letters of request, outfalls #2,#3,#4 and #5 are
primarily the outfalls of concern. Clearly outfalls #1 and #6 do not discharge stormwater from industrial
areas.
Based upon your discussions with Steve Ulmer, the stormwater discharges from outfalls # 2 and
#4 shall be considered representative outfalls for stormwater analytical monitoring. As mentioned in your
letter dated April 22, 1995, continued progress in "plugging" indoor floor drains that lead to these outfalls
is required. Elimination of the indoor floor drain connections to the storm sewers shall be completed by
November 1, 1995.
Visual observation shall be required at outfall #3. If deemed necessary, analytical monitoring at
outfall #3 may be required in the future. The requested determination is warranted and in accordance with
Chapter 40 of the Code of Federal Regulation part 122.21 (g) (7). We authorize you to sample at outfalls

Facility Name: Kenametal, Incorporated
NPDES No.: NCS 000171
Facility Location: SR 1.216 & SR1139
Henderson, NC
Vance County
Tyne of Activity: SIC 3399, Primary Metal Products, Not Elsewhere Classified
Recgiv,-ing Stream Name and Classification:
Joe's Branch, a class C NSW stream in the Tar -Pamlico River Basin and
Martin Creek, a class C NSW stream in the Tar -Pamlico River Basin
Proposed Permit Requirements: See attached draft permit
Compliance Schedule: See Part I, Section B of attached draft permit
Basis for Monitoring Requirements:
Review of the submitted monitoring data indicates that potential parameters of concern
include TKN, Nitrate plus Nitrite Nitrogen, BOD5, COD, TSS, and pH. A combination
of these parameters were reported at or above stormwater permitting benchmarks at
outfalls 002, 005, and 006. No samples for pH were reported for any of the 6 listed
outfalls. Monitoring with cut-off concentrations is recommended for each of the above
listed parameters, including pH.
The maximum reported Cobalt grab sample is 0.23 mgll and there is no benchmark
information available for that parameter. Discussions with Larry Ausley, Aquatic
Toxicology Lab, revealed that the maximum reported concentration of 0.23 mg/l would
not appear to be of concern in stormwater discharges. Since Nickel was also reported at
acceptable concentrations, no monitoring is recommended for either parameter.
Basis for Other Requirements: NIA

During the rain event of 9/25/92, reported previously, flow was measured at each outfall
using a one (1) liter container and a stopwatch. Total flow was estimated by taking'
the total plant area times the rainfall to determine total gallons collected. This
number was multiplied by 0.75, assuming 25% of the water is absorbed into the ground.

PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40
CFR § I22.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure
Certification must submit a No Exposure Certification NOI form to the Division; must receive
approval by the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit; and must reapply for the No Exposure Exclusion once
every five (5) years.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that has been
adequately treated and managed in accordance with the terms and conditions of this individual
permit. All stormwater discharges shall be in accordance with the conditions of this permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or approval.
The stormwater discharges allowed by this individual permit shall not cause or contribute to
violations of Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or
decree.

SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the 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.

2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In 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. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
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 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 any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural. Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
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
Part I Page 4 of 10

• • Permit No. NCS000171
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, stonnwater 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 Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of. the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part I I Page 5 of 10

0
• Permit No. NCS000171
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, including the log of the sampling data and
of actions taken to implement BMPs associated with the industrial activities, including
vehicle maintenance activities. Such documentation shall be kept on -site for a period of
five years and made available to the Director or the Director's authorized representative
immediately upon request.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.
