Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

RE: Kennametal, Inc., Henderson, NC; Stormwater DMR submittal Summer 2016; NPDES NCS000171
Kennametal was unable to collect storm water samples for the monitoring period ending October 31,
2016. Although rain forecasts were routinely monitored to predict a measureable and qualifying event, the
following obstacles prohibited the collection of samples:
• The precipitation did not materialized,
• The precipitation occurred when our contract laboratory was closed and holding times for samples
would be exceeded;
• Precipitation occurred without adequate time to mobilize to the site.
Therefore, we attempted to collect samples at the next available event which appeared as if it would
provide a measurable event. The event on November 3, 2016 however only resulted in 0.10 inches of
rain. Enclosed in this letter we are providing a discharge monitoring report for the facility representing no
flow for the monitoring period since this was not a measurable event. We will perform another sampling
event for the facility for the current monitoring period ending in April 2017.
Should you have any questions, please feel free to contact me at any time on my cell phone at
252.430.4498 or during regular business hours at my office phone of 252.430.3303. or via email at

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, If applicable.
A "representative storm event" is a storm event that measures greater than 0.1 Inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfaIl. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By this signature, I certify that, this rgpgrt is accurate and complete to the best of my knowledge:

HIGHLIGHTS: The general population is exposed to low levels of cobalt in air,
,t
water, and food.. Cobalt has both beneficial and harmful effects on "health.:.. At
low levels, it is part of vitamin 1312, which is essential ,for, good health. At high
levels, •It may harm the lungs and heart. This chemical has been found in at
least 426 of the 1,636 National Priorities List sites identified by the, ,
Environmental.Protection Agency (EPA).
What is cobalt?
Cobalt is a naturally occurring element found in rocks, soil,
water, plants, and animals. Cobalt is used to produce alloys
used in the manufacture of aircraft engines, magnets,
grinding and cutting tools, artificial hip and knee joints.
Cobalt compounds are also used to color glass, ceramics
and paints, and used as a drier for porcelain enamel and
paints.
Radioactive cobalt is used for commercial and medical
purposes. 'Co (read as cobalt sixty) is used for sterilizing
medical equipment and consumer products, radiation therapy
for treating cancer patients, manufacturing plastics, and
irradiating food. "Co is used in medical and scientific
research. It takes about 5.27 years for half of I Co to give
off its radiation and about 272 days for "Co; this is called
the hal f-I i fe.
What happens to cobalt when it enters the
environment?
❑ Cobalt enters the environment from natural sources and
the burning of coal or oil or the production of cobalt alloys.
❑ In the air, cobalt will be associated with particles that
settle to the ground within a few days.
❑ Cobalt released into water or soil will stick to particles.
Some cobalt compounds may dissolve.
Q Cobalt cannot be destroyed. It can change form or attach
to or separate ,from particles. Radioactive decay is a way of
decreasing the amount of radioactive cobalt in the
environment.
How might I be exposed to cobalt?
0 You can be exposed to low levels of cobalt by breathing
air, eating food, or drinking water. Food and drinking water
are the largest sources of exposure to cobalt for the general
population.
U Working in industries that make or use cutting or grinding
tools; mine, smelt, refine, or process cobalt metal or ores; or
that produce cobalt alloys or use cobalt.
❑ The general population is rarely exposed to radioactive
cobalt unless a person is undergoing radiation therapy.
However, workers at nuclear facilities, irradiation facilities, or
nuclear waste storage sites may be exposed to radiation from
these sources.
How can cobalt affect my health?
Cobalt can benefit or harm human health. Cobalt is
beneficial for humans because it is part of vitamin 1312.
Exposure to high levels of cobalt can result in lung and heart
effects and dermatitis. Liver and kidney effects have also
been observed in animals exposed to high levels of cobalt.
Exposure to large amounts of radiation from radioactive
cobalt can damage cells in your body from the radiation.

Page 2 COBALT
g CAS #7440-48-4
You might also experience acute radiation syndrome that
includes nausea, vomiting, diarrhea, bleeding, coma, and
even death. This would be a rare event.
How likely is cobalt to cause cancer?
Nonradioactive cobalt has not been found to cause cancer in
humans or animals following exposure in food or water.
Cancer has been shown, however, in animals that breathed
cobalt or when cobalt was placed directly into the muscle or
under the skin. Based on the laboratory animal data, the
International Agency for Research on Cancer (IARC) has
determined that cobalt and cobalt compounds are possibly
carcinogenic to humans.
Exposure to high levels of cobalt radiation can cause
changes in the genetic materials within cells and may result
in the development of some types of cancer.
How can cobalt affect children?
We do not know whether children differ from adults in their
susceptibility to cobalt. However, it is likely that health
effects in children would be similar those in adults. Studies
in animals suggest that children may absorb more cobalt than
adults from foods and liquids containing cobalt.
We do not know if exposure to cobalt will result in birth
defects or other developmental effects in people. Birth
defects have been observed in animals exposed to
nonradioactive cobalt. Exposure to cobalt radiation can also
result in developmental effects.
How can families reduce the risk of exposure to
cobalt?
Children should avoid playing in soils near hazardous waste
sites where cobalt may be present.
Is there a medical test to show whether I've been
exposed to cobalt?
Cobalt levels can be tested in the urine and blood within a
couple of days of exposure. Your doctor can take samples,
but must send them to a laboratory to be tested. The
amount of cobalt in your blood or urine can be used to
estimate how much cobalt you were exposed to. However,
these tests cannot predict whether you will experience any
health effects.
Two types of tests are available for radioactive cobalt. One
is to see if you have been exposed to a large dose of
radiation, and the other is to see if radioactive cobalt is in
your body. The first looks for changes in blood cell counts
or in your chromosomes that occur at 3 to 5 times the annual
occupational dose limit. It cannot tell if the radiation came
from cobalt. The second type of test involves examining
your blood, feces, saliva, urine, and even your entire body.
It is to see if cobalt is being excreted from or remains inside
your body. Either the doctor's office collects and sends the
samples to a special lab for testing, or you must go to the
lab for testing,
Has the federal government made
recommendations to protect human health?
The Occupational Safety and Health Administration (OSHA)
has set a limit of 0.1 milligrams of nonradioactive cobalt per
cubic meter of workplace air (0.1 mg/m3) for an 8-hour
workday and 40-hour work week.
The Nuclear Regulatory Commission limits radioactive cobalt
in workplace air to I x 10" microcurie per milliliter (µCi/mL) for
"'Co and 7x 10-1 µCi/mL for 'Co. EPA has set an average
annual drinking water limit of 1000 picocurie per liter (pCi/L)
for s'CO or 100 pCi/L for 'Co so the public radiation dose
will not exceed 4 millirem.

AND DISEASE REGISTRY
This fact sheet answers the most frequently asked health questions (FAQs) about nickel. For more
Information, call the ATSDR Information Center at 1-888-422-8737. This fact sheet is one in a series
of summaries about hazardous substances and their health effects. It is important you understand this
information because this substance may harm you. The effects of exposure to any hazardous substance
depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other

HIGHLIGHTS:." Nickel is a' naturally occurring element. Pure nickel .is'.a hard,
silvery -white metal used to make stainless steel and other metal alloys. Skin
effects are the most common" effects in people _who ,'are sensitive.: to"nickel
Workers who' breathed very large amountsof nickel compounds developed
chronic bronchitis and lung and, nasal sinus cancers.. Nickel has been found in ."
.at least, 882 of the 1,662 National Priority List sites identified by the -
Environmental Protection Agency (EPA)
What is nickel?
Nickel is a very abundant natural element. Pure nickel is a
hard, silvery -white metal. Nickel can be combined with other
metals, such as iron, copper, chromium, and zinc, to form
alloys. These alloys are used to make coins, jewelry, and
items such as valves and heat exchangers. Most nickel is
used to make stainless steel.
Nickel can combine with other elements such as chlorine,
sulfur, and oxygen to form nickel compounds. Many nickel
compounds dissolve fairly easy in water and have a green
color. Nickel compounds are used for nickel plating, to color
ceramics, to make some batteries, and as substances known
as catalysts that increase the rate of chemical reactions,
Nickel is found in all soil and is emitted from volcanoes.
Nickel is also found in meteorites and on the ocean floor.
Nickel and its compounds have no characteristic odor or
taste.
What happens to nickel when it enters the
environment?
❑ Nickel is released into the atmosphere by industries that
make or use nickel, nickel alloys, or nickel compounds. It is
also released into the atmosphere by oil -burning power
plants, coal -burning power plants, and trash incinerators.
❑ In the air, it attaches to small particles of dust that settle
to the ground or are taken out of the air in rain or snow; this
usually takes many days.
❑ Nickel -released in industrial waste water ends up in soil
or sediment where it strongly attaches to particles containing
iron or manganese.
Q Nickel does not appear to accumulate in fish or in other
animals used as food.
How might I be exposed to nickel?
❑ By eating food containing nickel, which is the major
source of exposure for most people.
❑ By skin contact with soil, bath or shower water, or metals
containing nickel, as well as by handling coins or touching
jewelry containing nickel.
❑ By drinking water that contains small amounts of nickel.
❑ By breathing air or smoking tobacco containing nickel.
❑ Higher exposure may occur if you work in industries that
process or use nickel.
How can nickel affect my health?
The most common harmful health effect of nickel in humans
is an allergic reaction. Approximately i 0-20% of the
population is sensitive to nickel. People can become
sensitive to nickel when jewelry or other things containing it
are in direct contact with the skin for a long time. Once a
person is sensitized to nickel, further contact with the metal
may produce a reaction. The most common reaction is a
skin rash at the site of contact. The skin rash may also

CAS # 7440-02-0
ToxFAQ011 Inlernet address is httpahrww.atsdr.cd'c.gra�Itoxfaq.ht[III
occur at a site away from the site of contact. Less
frequently, some people who are sensitive to nickel have
asthma attacks following exposure to nickel. Some sensitized
people react when they consume food or water containing
nickel or breathe dust containing it,
People working in nickel refineries or nickel -processing plants
have experienced chronic bronchitis and reduced lung
function. These persons breathed amounts of nickel much
higher than levels found normally in the environment.
Workers who drank water containing high amounts of nickel
had stomach ache and suffered adverse effects to their blood
and kidneys,
Damage to the lung and nasal cavity has been observed in
rats and mice breathing nickel compounds. Eating or
drinking large amounts of nickel has caused lung disease in
dogs and rats and has affected the stomach, blood, liver,
kidneys, and immune system in rats and mice, as well as their
reproduction and development.
How likely is nickel to cause cancer?
Cancers of the lung and nasal sinus have resulted when
workers breathed dust containing high levels of nickel
compounds while working in nickel refineries or nickel
processing plants. The Department of Health and Human
Services (DHHS) has determined that nickel metal may
reasonably be anticipated to be a carcinogen and that nickel
compounds are known human carcinogens. The
International Agency for Research on Cancer (IARC) has,
determined that some nickel compounds are carcinogenic to
humans and that metallic nickel may possibly be
carcinogenic to humans. The EPA has determined that nickel
refinery dust and nickel subsulfide are human carcinogens.
How can nickel affect children?
It is likely that the health effects seen in children exposed to
nickel will be similar to those seen in adults. We do not
know whether children differ from adults in their
susceptibility to nickel. Human studies that examined
whether nickel can harm the fetus are inconclusive. Animal
Studies have found increases in newborn deaths and
decreased newborn weight after ingesting very high amounts
of nickel. Nickel can be transferred from the mother to an
infant in breast milk and can cross the placenta.
How can families reduce the risks of exposure to
nickel?
❑ Avoiding jewelry containing nickel will eliminate risks of
exposure to this source of the metal.
❑ Exposures of the general population from other sources,
such as foods and drinking water, are almost always too low
to be of concern.
Is there a medical test to determine whether I've
been exposed to nickel?
There are tests available to measure nickel in your blood,
feces, and urine. More nickel was measured in the urine of
workers who were exposed to nickel compounds that dissolve
easily in water than in the urine of workers exposed to nickel
compounds that are hard to dissolve. This means that it is
easier to tell if you have been exposed to soluble nickel
compounds than less -soluble compounds. The nickel
measurements do not accurately predict potential health
effects from exposure to nickel.
Has the federal government made
recommendations to protect human health?
The EPA recommends that drinking water should contain no
more than 0.1 milligrams of nickel per liter of water (0.1 mg/L).
To protect workers, the Occupational Safety and Health
Administration (OSHA) has set a limit of i mg of nickel per
cubic meter of air (I mg/m) for metallic nickel and nickel
compounds in workplace air during.an 8-hour workday, 40-
hour workweek..

-HIGHLIGHTS. Exposure to chromium occurs from ingesting contammated,food,
or drinking water or breathing contaminated workplace air. Chromium(VI)'at high.
levels can damage the onosiand cause cancer. Ingesting high levels of chromium(VI)
may result inane mia or damage to the stomach or intestines. Chromium(III) is'an
essential nutr><ent..JChromium has been found in at least 1,127 of the.-1,669 National
Priorities List sit61dentified by the Environmental Protection Agency (EPA).','
What is chromium?
Chromium is a naturally occurring element found in rocks,
animals, plants, and soil. It can exist in several different
forms. Depending on the form it takes, it can be a liquid,
solid, or gas. The most common forms are chromium(0),
chromium(III), and chromium(VI). No taste or odor is
associated with chromium compounds.
The metal chromium, which is the chromium(0) form, is
used for making steel. Chromium(VI) and chromium(III)
are used for chrome plating, dyes and pigments, leather
tanning, and wood preserving.
What happens to chromium when it enters the
environment?
❑ Chromium can be found in airsoil, and water after release
from the manufacture, use, and disposal of chromium -based
products, and during the manufacturing process.
❑ Chromium does not usually remain in the atmosphere,
but is deposited into the soil and water .
❑ Chromium can easily change from one form to another
in water and soil, depending on the conditions present.
❑ Fish do not accumulate much chromium in their bodies
from water.
How might I be exposed to chromium?
❑ Eating food containing chromium(III).
❑ Breathing contaminated workplace air or skin contact
during use in the workplace.
❑ Drinking contaminated well water.-
0 Living near uncontrolled hazardous waste sites containing
chromium or industries that use chromium.
How can chromium affect my health?
Chromium(III) is an essential nutrient that helps the body
use sugar, protein, and fat.
Breathing high levels of chromiuin(VI) can cause
irritation to the lining of the nose, nose ulcers, runny
nose, and breathing problems, such as asthma, cough,
shortness of breath, or wheezing. The concentrations of
chromium in air that can cause these effects may be
different for different types of chromium compounds,
with effects occurring at much lower concentrations for
chromium(VI) compared to chromium(II1).
The main health problems seen in animals following
ingestion of chromium(VI) compounds are irritation and
ulcers in the stomach and small intestine and anemia.
Chromium(Ill) compounds are much less toxic and do
not appear to cause these problems.
Sperm damage and damage to the mate reproductive
system have also been seen in laboratory animals exposed
to chromium(VI).

Page 2 CHROMIUM
CAS # 7440-47-3
Skin contact with certain chromium(VI) compounds can
cause skin ulcers. Some people are extremely sensitive
to chromium(VI) or chromium(III). Allergic reactions
consisting of severe redness and swelling of the skin
have been noted.
How likely is chromium to cause cancer?
The Department of Health and Human Services (DHHS),
the International Agency for Reseach on Cancer (IARC),
and the EPA have determined that chromium(VI)
.compounds are known human carcinogens. In workers,
inhalation of chromium(VI) has been shown to cause
lung cancer. Chromium(VI) also causes lung cancer in
animals. An increase in stomach tumors was observed in
humans and animals exposed to chromium(VI) in drinking
water.
How can chromium affect children?
It is likely that health effects seen in children exposed to
high amounts of chromium will be similar to the effects
seen in adults.
We do not know if exposure to chromium will result in
birth defects or other developmental effects in people.
Some developmental effects have been observed in
animals exposed to chromium(VI).
How can families reduce the risks of exposure to
chromium?
U. Children should avoid playing in soils near uncontrolled -
hazardous waste sites where chromium may have been
discarded.
❑ Chromium is a component of tobacco smoke. Avoid
smoking in enclosed spaces like inside the home or car in
order to limit exposure to children and other family members.
❑ Although chromium(III) is an essential nutrient, you should
avoid excessive use of dietary supplements containing
chromium.
Is there a medical test to determine whether I've
been exposed to chromium?
Since chromium(III) is an essential element and naturally
occurs in food, there will always be some level of
chromium in your body. Chromium can be measured in
hair, urine, and blood.
Higher than normal levels of chromium in blood or urine
may indicate that a person has been exposed to
chromium. However, increases in blood and urine
chromium levels cannot be used to predict the kind of
health effects that might develop from that exposure.
Has the federal government made recommendations
to protect human health?
The EPA has determined that exposure to chromium in
drinking water at concentrations of 1 mg/L for up to
10 days is not expected to cause any adverse effects in a
child.
The FDA has determined that the chromium
concentration in bottled drinking water should not exceed
l mg/L.
The Occupational Health and Safety Administration
(OSHA) has limited workers' exposure to an average of
0.0005 mglm3 chromium(VI), 0.5 mg/m 3 chromium(III),
and 1.0 mg/m 3 chromium(0) for an 8-hour workday,
40-hour workweek.
