INTERNATIONAL JOINT COMMISSION
1999 GREAT LAKES WATER QUALITY FORUM
MILWAUKEE, WISCONSIN
SEPTEMBER 24-26, 1999
LIGHTLY EDITED, VERBATIM TRANSCRIPT
SATURDAY MORNING, SEPTEMBER 25
QUESTIONS AND DISCUSSION
Hy Schwartz, Sierra Club
Harvey Shear is a neighbour of mine, but the purpose of my talk is very difficult. Very simple, I
am delighted. Ten years ago, when I first came to one of these meetings my hair was still
colored blond, we had all kinds of pickets screaming like mad at the government. Over the years
you have done a very, very good job. You've really encouraged us that the Great Lakes can be
rebuilt. It is a wonderful thing for me to hear and to congratulate you all of that. However, as
the story goes on the tv, that's only half the story.
What happens to the garbage? What happens to the toxins? What happens to the PCB and the
mercury? And all the other sediments that you pick up. What are you doing with garbage? Ten
years down the line the kids are gone. Ten, twenty years down the line they'll have a new
problem. Where are you dumping it? How are you reprocessing it? Are you re-using it? This is
a very major problem. It is the result of a good clean-up, but you still have to get rid of the
garbage, and how are you getting rid of it? Are you storing it in mines? Are you storing for 20
years down the line for a new set of problems? How to dispose of salvaged mercury, spent
nuclear fuel, all the other good stuff. It's a hard question. I don't expect an answer now, but I
just want a commitment that somebody will look into this. Are you going to put it into a garbage
box, an old mine place? What are you doing with it? How are you going to clean it up 20 - 25
years down the line?
Mr. Lyons
Before we respond to that, I'd like to ask Dave Cowgill to respond to Elaine's last question
regarding the funding, demonstrating the economic cost-benefit analysis.
Dave Cowgill, U.S. Environmental Protection Agency
Just a couple of things. One report that was released by the Water Quality Board, it's a draft
report on economic benefits of sediment remediation, is available and is also on the IJC Website.
The Northeast Midwest Institute out of Washington, D.C. has been conducting a Great Lakes
economics evaluation project. They have a panel of economists who are looking economic tools
for trying to work on techniques for providing values or estimating values of different
components of the Great Lakes ecosystem. It's a step in that direction. There are also a few
projects that have been undertaken. The Thunder Bay example was mentioned and where we
were going to provide some funding to the Northeast Midwest Institute to look at three Great
Lakes Areas of Concern to try to work on, and scope out, what techniques might be used to
estimate the economic benefit of sediment clean-up in some Areas of Concern. I think there are
lot of people who share your interest in this and are trying to make some headway on it. It is
very difficult.
Mr. Lyons
Thank you Dave.
Unidentified Speaker
Maybe I can just start by responding, at least preliminarily, to Hy's comments, and thank you
very much for those comments and questions. The question you raised about what are we doing
with the garbage is really a big challenge. Absolutely. There is no doubt that ...
Mr. Schwartz
Sorry if I put this a terrible, but it's a good challenge ...
Unidentified Speaker (Continued)
It certainly is. When you think about it from the point of view of contaminated sediment and
what we do when we take that out, each one of those, in some cases those situations are unique.
Some of them, we can look at remediating the sediment itself. We are doing that through buyer
remediation, as the Thunder Bay example that we used. Others, it may, containment may be the
best answer.
Mr. Schwartz
Where?
Unidentified Speaker (Continued)
Well in a secure facility in some fashion. The point I am making, Hy, is that each of those
situations are somewhat unique and we need to take a look at them and see what is best and
feasible for that situation. You also raised the issue of general household garbage. Certainly all
municipalities around the basin are struggling with how they handle that. This speaks to both the
amount that is going into the stream when each of us put it out every week to be picked up and
how we handle it at the receiving end. My only point is that I totally agree with you. It is a big
challenge and one that continues to keep us quite active.
Mr. Schwartz
When I said garbage, I meant the general term, PCBs, mercury, toxic chemicals. Are they
broken down or are you going to just keep them in a box somewhere, or can you take them apart
and re-use them?
Mr. Cowgill
Maybe I can ask John Carey to talk to some specifics about the toxics.
John Carey, Environment Canada
Well, I just would like to point out from the research side, because that is the side that I'm
coming from, the Great Lakes Program in both countries is sponsoring a lot of research and in
situ treatment, which is rather new. Rather than digging things up and moving them somewhere
-- if you don't want them here, move them over there -- what we are trying to do is find ways to
treat them while they are where they are. In fact, in Randall Reef, for example, in Hamilton
Harbour, that project that was mentioned before that's contaminated with PAHs, we are looking
at how we can inject nutrients to stimulate biological remediation while it's right in the
sediments, so we don't have to move it and create another problem somewhere else. I think that
the Great Lakes Program in terms of the research side, this is not, there's a few of these that have
been patented and are operational now and I can tell you that technology developed in the past is
part of the Great Lakes Research Program. It has been used in Boston Harbour, Hong Kong
Harbour, Hong Kong Airport to do in situ remediation. We are trying that but it's still an
evolving art. That is, we think, one of the directions for the future, just to address the issue that
you meant. It is still a research issue.
