Those are from a just release addition to the latest AP-42.  Those
particular numbers look about the same as the last time I looked
at a large bark boiler (pulp and paper mill).  On the other hand,
the new residential wood fire place section has some new additions 
which show the differences from a convential, cat and prefad system.
Its interesting.  Bark boilers make significant impact on an air
increment, so I think that the EPA and the Pulp and Paper industries
have updated the numbers.  Although emissions from residential
fireplaces need
to be included as an area source model, CO maybe the only pollutant
where
they make a difference, since fireplaces are not regulated after
installation there wouldn't seem to be much of need to reevaluate the
factors.  Since I work only in the southeast or rustbelt, which doesn't
have any CO nonattainment areas, I'm not that sure of need for these
factors.  For ozone nonattainment area, residential heating is not a 
large concern, as the exceedances occur during hot weather, not alot
of fireplace going in August.
I suppose that certain large cities have restricted woodfires.  I think
that SouthCoast Air District (LA) has restricted emission from char.
grills.  Glad I don't live out there anymore.

Yes, I agree.  But, sometimes a lower PQL/MDL is a double edged sword.  
Several states that I work with have a "clean til its clean" requirement
for reportable releases, (or do risk analysis) .  Whenever they are
trying to do a clean closure
type actions, why the only anal. test method is a 20 year old SW-846
method.  When risk analysis is needed, then its a state of the art
HPLC with magic gnomes.  Sometimes you just have to laugh.  Imagine,
industry bending science to fit its objective.

Which is exactly how the AP-42 manual works.  It is a high average
guidance, if you need to prove less emissions you pay for a source
testing company to do the work.  Often the 10 to 50K pays for itself in
reducing the need for unnecessary control equipment.  Although alot
of EPA and state regulators are alittle stubborn and pigheaded, they
tend to come around to appropriate science.
Alot of the information in AP-42 is cosponsored by the industry that is
being regulated.  After all, they have a stake in accurate and fair 
information.  Anyone who thinks that the U.S. EPA is some big bully that
pushes the poor weak refining industry around. well they probally also
think that pro wrestling is real.
You know, I have no understand of why the subjest should be the subject
of flames, and rant and raves.  I simply responded with some pointers
to emission estimates for woodsmoke.  Made not comments about it being
a good or bad thing.

There goes Joshua again, trying to pretend to scientific knowledge he
does not possess.  Molecular chlorine does not breakdown into Cl atoms
in the atmosphere.  In addition, atomic chlorine is highly reactive,
and would not "eventually" react, it would immediately react with
almost anything around.
Molecular chlorine is soluble in water, and reacts readily with
atmospheric moisture to form HCl.

Nomenclature problem here.  Ionic chlorine (Cl- as you wrote it) is
not a radical.  A radical is a chemical species with an unpaired
electron.  Ionic chlorine has all paired electrons.
To clear up a misconception you appear to have, it is absolutely
certain, known for sure, that ozone in the stratosphere decomposes.
Further, that decomposition is accelerated by chlorine.  Also, while
it is clear that natural sources of troposheric chlorine are some five
orders of magnitude greater than man-made sources, these are generally
in a form which is not not going to reach the stratosphere, due
primarily either to a high solubility or reactivity.
If you have read my posts, you know I am not an "ozone alarmist", and
I would not lead you astray on this point.
There are weak points in the popular vision of the "ozone alarmist",
but the question of CFC contributing to ozone decomposition in the
stratosphere is not one of them.

Wouldn't work.  The most expensive public works project in the US
right now is the Big Dig at $7.8B and counting for 7 miles of road and
tunnel.  Even the most optimistic projections say that this will not
solve the traffic problems (though it will ease them a bit).
Some 15,000, IIRC, cars and trucks are using the billion-dollar Ted
Williams tunnel (first completed segment of the Big Dig, it connects
South Boston to the airport and will connect, in several years, to the
Mass Pike).
For a relative pittance, the entire Old Colony Railway is being
restored for commuter rail use.  Less than $200M if I remember my
numbers correctly.  They're looking at serving over 12,000 riders a
day on the 3 branches of this line.
Locally, it was estimated that rail service extensions from Lowell to
Nashua NH would cost anywhere from $26M to $80M.  This would hopefully
alleviate the incredible congestion along US-3.  The NHCH
(Nashua-Hudson Circumferential Highway) was originally designed as a
12-mile bypass through Nashua whose cost was running upwards of $200M.
Now, it has been cut back (only 2 of the 3 segments will be built, it
appears) and I have a hard time believing current statements about how
eliminating 1/3 of the highway is supposed to save half the cost when
that one third was the easiest part to build (lowest density
population, no bridges, etc).

If you live in a major city, imagine how bad the traffic jams would be
if, for example, commuter rail just stopped.
In NY it was a nightmare when there was a transit strike.
In Boston, you'd be flooding the already overcrowded highways with
over 50,000 more cars.
As I recall, you're in the Chicago area.  Can you imagine what would

For the record, if I took transit, I double my commute time.  In
addition, I still ahve to drive 15 miles into the center of a
drug-ridden city to GET to transit.
While other arguments may be real or ephemeral (go ahead, try to put a

every time.  It boils down to me being able to spend an extra 10 hours
per week with my family.  No amount of reading a newspaper on a train
can make up for that.
..and mind you, I like taking the train and did so for years until I
had to economize my time.

About half of the 0.56 deg C increase in the past one hundred years
can be explained by variations in solar irradiance alone.  The
remaining approx one quarter degree may indeed be due human activity.
I do not recall denying that.
But unlike you, I don't think we can know yet.  We are looking for a
small long term trend in the face of a large natural variation, always
very hard to do.

First, you demonized the AP-42 table, which is not a
rules table but an emissions estimate reference.  It
has nothing to do with the USEPA justifying its 
existance but in giving industry a way to estimate
their emission impact without spending a whole lot
of their own money.
Second, you thought that these quantities were in 
AP-42 were not there 10 years ago, which is untrue.
The data for AP-42 stretches back well over 10 years.
You failed to respond to either point . . . running
outside the baseline.

You confusing safe with relatively insignificant.  The concept
is one which a lot of Greenpeace folks hate to look at ,the
overall stance of Greenpeace is to block any new fossil fuel
plant.
Almost (if not all) fossil fuel burning leads to some emissions.
Natural gas has products of incomplete combustion (PICs), along
with the production of carbon monoxide (CO) and oxides of 
nitrogen (NOx).  Coal does also, but I'd rather be burning 
natural gas all things considered.  Burning fuel produces 
pollution - bottom line.  Can't get away from it (at least now).
We can minimize its impact - catalytic converters from cars,
improved combustion controls, and air pollution control tech. Or
we can choose cleaner fuels (such as natural gas).  But don't
absolve the argument of a fundamental problem - burning fossil
fuels produces pollution.  And that includes wood.  You have
repeatedly hailed to natural forest fires as some placebo in the
debate, but the problem is not the background level pollution.
It IS ALL THE OTHER BURNING by people, particularly around people,
or for the sake of farmland (in developing countries) that is
increasing the pollution levels.  And it can be looked at either 
locally (in cities and in concert with other emission sources) or
globally (savannah burning yielding a huge impact in greenhouse
gas emissions).
Is it "safe."  Sure, everything is relatively safe (insignificant)
when burned in small amounts, but MAY become a problem when other
of the same or different air pollution problems are considered.
So when residential wood fires are controlled, it isn't because 
we have discovered anything new, or minute quantities of stuff we
didn't think existed before, or are claiming huge differences
between residential and natural.  What is being claimed is that
burning wood, combined with other folks burning wood, localized
industrial sources, and cars, is bad (no brainpower required).
This is why we have the rules and why we have smog watches, etc.

First, the overall emissions of CO and NOx end up being huge
when considered from singular sources like boilers and power 
plants, or an aggregate of all the cars, localized sources,
and woodfires, lawnmowers, etc.  The toxics (those with
relatively small numbers per ton) are likewise treated.  One
source no problem - a lot of sources, then all those compounds
start to have an impact.  Particularly IN A CITY before 
everything disperses - comparing this to forest fires is
a huge mistake (freshman high school level) because we are
talking about immediate exposure to folks living next to the
source.  The only way you can ignore this is with tobacco 
comany research (that research that says statistics mean 
nothing in the face of overwhelming research that says 
otherwise).
Second, some extremists or others whose only exposure is
to extremists (see anti ditto-head) think any exposure is
too much.  Again, only education can resolve the lack of
knowledge some have about their lifestyle (consuming) and
industry's role in it, and what is reasonable - e.g. you
can't have a dishwasher or cars and expect no emissions. But
the current conservative platform is to disband education,
disembowel student loans and grants, instead of SOLVING the
problem - which is probably a problem with education also. :<)

Again, you are failing to realize that finding lower levels
of pollutants is actually good for industry.  It also allows
us to measure and research actual numbers instead of theorizing
about low levels.  There are insignificant risks associated with
the consumption of fossil fuel, but it is not always the case
and when combined with other sources it can lead to problems.  
And I wasn't the one who demonized the AP-42 tables (this is 
really funny to those of us in this business), so I think the 
idea of "scare tactics" is in your court, not mine.  And burning
wood in your fireplace during times of ozone/smog alerts or
during seasonal bans when impacts are worse is a personal 
failing of yours in not considering the health of the people you 
live next to - and if you have children I think you need to
reevaluate your priorities in life, they don't have a say in
the matter.

They are run by a mechanical linkmage to the engine, which requires a shaft seal; also, there 
are multiple connections between the compressor and the hot and cold coils. Your refrigerator is 
totally sealed; no hoses, connections, or seals.
If your car  A/C was a sealed 12 volt unit, it would help. It could be all-copper tubing with no

The only source that I'm going by is the "draft" EPA report on dioxin.
There where several references that I did not follow-up on.  I have
seen these numbers used as a reason not to use controls for a pulp
paper plant, as the predicted release of dio/fur would be much less than
a 100 acrea fire.  I have little professional reason to follow-up on
forest fire numbers, I've never had a client that needed help in getting
a permit for a forest fire.  As pro environmentalist as that dioxin
paper was, I tend to believe that the numbers would be conservative.  I
was shocked at how slanted the draft was, which might be why its not

You mean creosote, the Aromatic ladden witches brew that forms inside my
chimneys.  All of the PCDD/F formation is a surface activated formation,
the PCDD/F forms on the fine particulates in the flue stream.  Surface
quench should not form dioxin.  
I ran a sample of creosote through a RCRA characterization test once. 
You 
don't want to know how bad is was.  Needless to say, I wear good gloves
and wash them twice afterwards.  Also wear my dust mask.

Now, as you seem to have some familarity with the chemistry of PCDD/F
formation, you know that a hotter combustion temperature may increase
formation. Its tricky chemistry and well nigh impossible to accurately
estimate formation rates.  If I had to guess, I would say that the
U.S.EPA compliant woodstoves might produce more that a colder older
flue.  But, it would be a guess.
But, it don't really matter.  No one that I know of whats to regulate
residential wood stoves and fireplaces.  It would be plain silly.  There
are a set of U.S.EPA new source performance standards that regulated the
amount of CO and particulates in a new unit, but that is for a
completely
and totally different reason.  As suprising as this is to me, a bunch of
people do not like to see thick gray hazes in the morning skies.  Some
people dislike the smell of wood smoke.  Me, I grew up around it.  It
makes me remember my childhood and better days.  A thick cloud of wood
smoke makes me happy.  I have met many people who crinkle their nose and 
complain about the stink.  Oh well, one of the drawbacks of democracy.
I have been out in the Rockies when the cumlative haze from all of the 
woodburning causes visibillity problems.  Have also seen the Denver
air modeling that indicates that part of the problem with them exceeding
CO levels is from the wood burning.  
Now, bark boilers and industrial waste wood boilers are different
matters.
There have been some high profile permit/constructions.  Testing has
been done, by an independent contractor of course, that show detectable
and significant dioxin production (U.S. EPA method 24), from a waste
wood
boiler(no added source of chlorine, no bark).  I make no comments nor
imply any about any elevated risk that this imposes.  A majority of the
local citizens where concerned about these projects.  This being a
democracy, when a majority is concerns action is taken.
Damn, my shoulder hurts,. been cutting wood for winter most of the

Very little.  How many coal or oil fired plants prior to the last half
century, compared to now?  How many automoblies?
There has been an approximate 0.56 deg C warming since 1610.  Almost
half of that may be explained by simply variations in solar
irradiance.  It may be that CO2 from human activity is contributing to
the approx one quarter degree not explained in this way, but there are
probably other contributors as well.
I don't think we can say that yet.

Perhaps. If you didn't avoid factual evidence so much we might know what you're

I agree that my neighborhood has been overrun with humans. I an most others
don't agree that our parks (with a few exceptions) are overrun with humans. 
Most of the time I go to our nearby parks I see, at most, two or three people 
in the course of a couple of hours. I have a hard time believing that wildlife 
sanctuaries are overrun, but I'm not a biologist so I've never actually been 
to one. I've just seen hundreds (perhaps thousands) of acres where no one ever 
goes, and wonder why you call those "overrun".

Of course you realize that most people don't agree with you. Your web page
is littered with recollections of park rangers and major organizations (i.e. Sierra
Club) that haven't agreed with you. Even your REFERENCES don't agree with you 
(I'll get the specific quote if you wish).  Just because have extremist views doesn't
make you Gandhi.What I'm saying is that SOME progress (what we've made) is better
than no progress at all (what you've made). Failure for the right reasons is still

Five years ago, I got roped into doing the stats on contaminants in 
Northern Ontario fish (lake trout) for people doing sport fish consumption
guidelines.  There were no detectable PCDD/F TEQs in fish, except in fish 
taken from waters downstream of paper mills. There have been some
other analyses of northern Canadian biota that show only negligible
PCDD/Fs.  So where does all the forest fire dioxin/furan go, if it's
created in the first place?
Looking at the various numbers cooked up for forest fires, all I see
are indirect inferences based on old total PCDD data from certain
kinds of controlled burns.  I have yet to find a report from someone
that went out and systematically measured PCDD/Fs in soils, sediments, and
biota from areas where forest fires have occurred sometime in the
recent, say 1-25 year, past. Until I see some hard direct evidence, I'll 
remain skeptical about the significance of forest fires as major PCDD/F 
sources.

...its certainly true in the models. Temperature changes in the tropics are the most
significant (measured as change divided by s.d.). Other variables (mslp, for example)
are different.

Now why should people owning forests wish to cover them with concrete?
And why should states owning forests wish to cover them with concrete?
I know a lot of people owning and caring about forests, about half of
the forests in Sweden are private property. I have also noted that the
state and state owned companies has not hesitated for a moment to
build things replacing forests ore much worse use and by law enforce
on others ways to run the foirests that hurt their ability to sustain

This has to be true since Vandeman himself hasn't responded and called

Nope, bacterial destruction does very little to destroy CFCs.  There

Harold my child, I was doing photochemistry of small molecules
while you were sucking on your thumb,  any Cl2 exposed to

Another fate.  Guess I missed that one., but it still depends on the
solubility and the relative humidity and time of day as to
what the fate of the Cl2 is.

If I were an environmentalist, I wouldn't want a semi-natural source
like
forest fires being the largest single source of dioxin.  It would seem
to
be an industiral side point (our emissions small in comparison).
I concur, that estimating has to be suspect.  Would a high moisture
softwood fire produce anything at all like a dry hardwood forest fire
like we would have here.  Would they compare at all to the widspread
Amazon area fires.  I wouldn't bet my license on it.
It would seem that by measuring the dioxin in a pm10 grab sample in an
ambient air sample after a large area fire, like the California fires,
you could get a fair estimation.  But, like I said, its not an area that 
concerns me much.  No money in helping with those permit for a forest
fire.  Contrary to Rush limberger, the EPA does not require a permit
before your volcano can blow.  Area source, not a point source. 
Huh, what detection level were you looking at in fish fat?  I would have
expected getting a detection on almost all samples.  I know everything 
caught out of the Ohio has detectable levels, not enough to issue an
advisery but detectable. Because of Fecal Coliform, heavy metals, and
PCB's we do have warnings.

Subject: Q: Wind-emission vs air-'stripping'-emission in waste water bassin
From: RITS@XS4ALL.NL (Richard Ritsma)
Date: Mon, 07 Oct 1996 18:06:35 GMT
Dear readers,
I'm looking for some answers about the above subject
(Wind-emission vs air-'stripping'-emission in waste water basin)
I'm doing a measurement above a waste water basin (400 sq meters and 4
meters high) The waste water is mixed with air "bubbles", with a compressor
(500 cubic meters per hour).
The measurements concerns the amount of stripped solvents, like toluene and
dichloromethane. I've placed a 'hood' over a big bubbled area, that
contains enough air for my sample-pump (ca 5 liter/min). The assumption is
made that the concentration of solvents in the airbubbles are the same in
the whole basin.
The measurement is done with a FT-IR spectrometer.
The concentration of solvents in the water before and after the basin are
being monitored with a gaschromatograph with purge and trap.
The scope of the measurement, is to what degree;
1 is the decay of the solvents, (biological decay)
2 is the emission (and wind emission) 
Now I like to know what the contribution of the wind will be on the total
solvent emission by an average wind speed of 5 meters/second.
Because the wind emission is difficult to measure, is this higher than the
emission of the stripping by air? Or is it predictable low?

  Ignore the fact that people have already made hindcast runs.
  What would you accept as a predicted variable, and what
degree of precision would you require before you agreed that
the prediction was successful?
  For example: 
  Variable:  Average global surface temperature as measured by the
thermometer network for the year 2010.
  Precision of agreement: 0.01 C (or whatever it is you like).
  Of course, in making the requirement of a prediction, rather than
retrodiction or hindcast, you also are requiring that the people
conducting the runs have a perfect knowledge of future solar
variability, the future of greenhouse gas releases, and the future
volcanic emissions among many other things.

   Tom Steegmann will reply to you by saying that Tom Steegmann
wouldn't vote for Bob Dole if he came to Tom Steegmann's house and did
Tom Steegmann's laundry for Tom Steegmann.  It also makes Tom
Steegmann very uncomfortable when 'the others' refer to 'themselves'
in the third person.  It is as if Bob Dole is not actually in the body
that you see on TV, but rather is just a brain floating in a
laboratory somewhere in Shawnee Mission, Kansas.  The thing you see on
TV is a complex bio-mechanical body substitute built and programmed by
newt gingrich and his minions.  Tom Steegmann eagerly awaits your
reply.  Tom Steegmann says have a nice day.
