Re: Perc bans


Using perc is a PROBLEM for those users.  They should be trying to get at the 
ROOT CAUSE of their problem and not trying to find "right answers" and "safe" 
alternative chemicals.  As you know, the cause and effect diagram is a great 
tool for looking at the perc use at each site.  You can download a paper on 
this topic from my web site in PDF format (Practical Pollution Prevention 
Reprints-Using a Cause and Effect Digram).  It is provided below.  I suggest 
this to you because it simultaneously examines technology, materials, methods, 
and the people themselves.  The State of New Mexico is sponsoring some training 
on this and other related tools on October 22-23, 1998.  You may wish to 
contact Pat Gallagher (505/827-0677) for more information.  

There have been a couple of papers written lately that show that safe 
substitutes (aqueous-based machine coolants and isopropyl alchol cleaners) may 
improve the environment, but they pose a safety threat (harboring Legionnaires 
Disease and flammability, respectively) to the workers.  We cannot tolerate a 
shift from environmental excellence to serious degradation in the welfare of 
workers and people living close to the facility.  We cannot tolerate a shift in 
the environmental impact from the facility to another point in the lifecycle 
(using ultrasonic cleaners with more energy to a power plant) without taking 
note of this shifting in impact.  Cause and effect diagrams (the most commonly 
used problem-solving tool in the world) can help you do just this.

By the way, there is a problem-solving and decision-making guide on my web site 
that was developed on an EPA Environmental Justice Grant.  It is designed to 
help micro-businesses (one or two people) use the tools in the Systems Approach 
to Pollution Prevention.  The State of New Mexico has adopted this guide to use 
in their new Environmental Excellence Program (Green Zia).  It will work great 
for those small industries that you note in your e-mail message.

Let me know if I can answer any questions that you may have on this important 
P2 tool.

So if I was using PERC, and wanted to get away from it, what would I
do?  The sites I looked at said "we are redesigning the process...working
on changing the industry etc..."  It sounds like there aren't many
alternatives out there for a shop, but I know there must be some specific

Specificly, we are working with some facilities that need to clean grease
off employee uniforms.  They want to use "an environmentally friendly
soap."  These facilities are south of the border, and probably won't make
large capital investments.  

Any ideas?
