I was told today that the EPA stopped by the college and warned us they
would return in July to inspect the entire college.
Frank...
A couple of years ago, I received a frantic phone call from the art
department chair at the local college. The EPA inspectors were there,
visited the excess materials storeroom in the basement of one of the
buildings, and were having conniptions regarding the old bags of stored
clay and glaze materials. Some of this stuff is really old (like probably
half a ton of original Colemanite!). The EPA folks said they could not
find expiration dates on the bags, and they wanted to know how old
everything was so they could determine if it had to be disposed of, and if
dates could not be proven, everything had to go! The department chair
asked me, "We can't afford to lose all of this stuff! What do we tell
them?"
I told them to respond to the EPA folks that while we cannot provide an
exact date, all of the materials were at least several million years old!
The inspectors were not satisfied with that, so I explained to them that it
was all crushed dirt and rocks, and dirt and rocks do not "expire". I
asked them to show us the regulations covering expired dirt and rocks so
that we could comply. They made a few phone calls, finally said that they
had to discuss it with their supervisors, and we never heard from them
again.
A young friend of mine just inherited the ceramics program at a small
college. Their gas kiln is inside the studio proper, rendering the space
hot, noisy, and stinky. He wanted to move the kiln outside, but the
college didn't want to spend the money. He arranged for an EPA inspector
to come to the studio to look at the kiln and find a reason why it had to
be moved outside (fumes). I received a text, "EPA guy is here. Doesn't
know what he should be testing for. What do I tell him?"
I had a very similar experience early in my Wall Street career, when I was
managing a trading room at a good sized retail brokerage firm. We had our
annual SEC (Securities and Exchange Commission) audit. The inspector
interviewing me asked if we were in compliance with Rule ACB-123 (I don't
remember the specific rule number). I replied, "I don't know. What is
that rule about?" He said, "I don't know either, so we'll just say you
are"! Your government in action! Don't you feel secure?
I guess what I am trying to say is that the folks who arrive probably won't
have much of a clue, and will probably ignore real threats and focus on
trivialities. If it's an easy fix, just humor them. If it's something
daunting, politely ask for a rule number so that you can formulate a proper
compliance procedure. I'm guessing there won't be a rule at all regarding
ceramics materials, since they are pretty much all "natural", kind of like
our old local building inspector who would make up his own requirements,
knowing that no one would have the guts to challenge him..
Your mileage may vary, but for our local college it ended up being no big
deal. All of the ceramic materials, including colorants, are in plastic
containers on open shelving or in bulk tilt-out bins under the table in the
glaze lab. The only things labeled "Toxic" are a few of the particularly
nasty items I personally labeled about 10 years ago, on my own, just to
scare the kids away from them unless they knew what they were doing (mostly
some nasty chrome and nickel compounds). The EPA folks had no problem that
I know of with any of it. I did read somewhere a possibly apocryphal story
about another college that was forced to install all kinds of water
filtration stuff and particulate recovery nonsense. I don't believe it's
true, and I don't believe there are really such regulations, but I'm
certainly no expert.
Good luck!

There seems to be a BIG DIFFERENCE BETWEEN INSPECTORS.
I have a row of small plastic trash cans that I fill with glaze making
ingredients like F4 spar and potash etc. but no oxides/carbonates.
They are not covered. Will that be a problem? I place the scale in front of
them and can mix a bucket of glaze lickety split.
We use plastic lidded trash bins, 5 gallon lidded buckets, even plastic

brandon2@SUPPORTYOURLOCALPOTTER.COM on tue 15 may 12
We had an EPA visit last spring, the art dept was frantic. I made sure
that everything was labeled, and contained. No open bags, except for
clays in the mixing room. We all made sure to have MSDS sheets for every
last thing, and that they were accessible. When they showed up all they
seemed to care about were kiln fumes and what went down the sink. Our gas
kilns are outdoors and our electric kilns were properly vented. We only
had a clay trap on 1 out of 4 of the sinks, we were cited for that, was
happy to deal with that. The only big deal is that we are no longer
allowed to have ANY glaze material go down the sinks. We have to get a
haz-mat barrel for dealing with glaze residue(not sure how that's gonna
work.) The materials they were concerned with going down the sink were
zinc, chromium, copper...metals mostly. We were supposed to have
implemented these changes this last school year but haven't because I
can't understand how to deal with the glaze situation. I can't even
imagine how fast we'd go through those haz-mat barrels, and then having to
pay to have them hauled off. Sheesh. We'll probably set one up to
maintain the illusion, but it's just not an acceptable reality. Gotta
love the one size fits all regulation. Our inspectors were really nice
and made the process pretty painless, but I definitely feel their presence
was more of a nuisance to education than help to the environment.

epa shouldn't have anything to say about material storage unless it is
at risk of leaking into the ground water somehow. not likely in most
ceramics buildings. They might, however, be interested in what and
how much of it you are flushing down the drain. your risk management
and safety people ought to have told you about these limits 20+ years
ago, but it is possible you slipped through the cracks. Our hazardous
waste people only started stepping up their game about 5 years ago
with any sort of seriousness.
People working here were most concerned with stack and exhaust vent
emissions, but the epa decided we weren't an industrial pollution
source of any sort and moseyed on by. OSHA people, on the other hand,
they don't care so much goes into your waste stream, but they do care
very much about indoor air quality and safety systems, such as having
automatic flame shutoffs on your kilns, etc. Sadly for me as a state
employee, OSHA has no say at all in the workplace safety rules around
here.
As far as preparation for a visit from any safety people goes, you
should just do what you normally do, i.e. show them your clean and
orderly studio. Lids on glaze buckets, all raw materials stowed
safely, *EVERYTHING* with labels. you do this already right? Because
if you don't you should. If you don't keep lead, or uranium, or
cadmium around, they are probably not going to hassle you too much.
The key to dealing with these people is to come across as though you
know what you are talking about. Know that you have chrome (III)
oxide, not chrome (VI) oxide in your bins. that is what we use, after
all, but they see/hear chrome, and they think hexavalent chrome, and
then draw the false conclusion that everyone is going to die! Impress
them with the fact that you already have a safety oriented mindset
(which if you don't, you should), and point out improvements that you
have made to the place during your tenure there. Most importantly, as
when dealing with all other humans, and especially with humans who
happen to be bureaucrats, treat them with respect and kindness. This
works wonders, even if you are in gross violation of some safety
code. Don't bow down to them and put them in a power position, but
treat them as your equal and as well as you would any other person,
and you will have good dealings with them unless they are a total
arse. and at that point you ask for the name of their supervisor.

Several years ago our college safety official got all of us in the
sciences, automotive, the arts- anything dealing with materials or
potentially hazardous conditions together and said each of us were the
experts in our own areas and needed to learn about material handling,
labeling and safety.
I educated myself about proper hazard communication, handling and
labeling. We have ALL material containers labeled with haz mat lables
(example:
http://static.seton.com/media/catalog/product/Hazardous-Material-Poster-D58
-ba.jpg ), the entrance door to each room/studio has a haz mat label for
emergency responders and we keep up to date MSDS for everything stored at
the studio. I have a written communication plan and have even had the
settlement tanks next to the sinks tested (passed ok)for hazardous metals.
We have DEQ (the state arm of EPA) come through, walk with them, show them
signs, documents, answer questions, they smile, shake my hand and walk
away.
It's not hard, it's something every public studio should/must do - it's
for my own health and safety!

In the back of my head i remember reading something about the ceramics dept
at the University of Oregon doing research on fusing glaze waste into
pavers that could be used outdoors. (Hank Murrow mighht have a contact
there.)
This reminds me of the nuclear waste glassification project that's being
done at Hanford. there's sure to be public documents and other info. on
the internet that you could glean for your on purposes.

That is their mandate, environmental protection. they couldn't give a

others.

Can't you add cobalt and make a waste glaze? Easy enough to set up a
rinse barrel with overflow.

Indeed, the U of Oregon forms glaze waste with clay and fires it to form =

pavers that are used in the courtyard, which is a boon in our wet =3D

I was concerned that this was going to be an issue for us. It would
have been, but we cut out the thing that they didn't want going down
the drain, barium carbonate. this may not work for some people's
programs, but we find there are enough interesting things that we can
do without it. The only other requirement we were told was that
lithium carbonate could not make up more than 1% of our waste stream,
or it would be regulated. since most of our waste is in the form of
silica, alumina and iron oxide, this ended up not being a problem for
us with our safety people. Find out exactly what they don't want down
the drain, and in what maximum quantities will cause you waste to
become designated as hazardous wast and you can probably go back to
washing stuff down the drain if you comply. Though you shouldn't be
disposing of mass amounts of glaze down the drain, it clogs the pipes!
don't waste your energy trying to turn large quantities of waste glaze
into glass. you do far more environmental damage wasting all that
fuel trying to turn the glazes waste into glass. do what mel
sugested and throw a scoop in with your clay when you mix it if you
can't find a better way to get rid of it. Or just stop using toxic
ingredients. you'll get over them.
