Dear Dr. Frederickson, 
Enclosed you will find a copy of my written testimony for the 
Advisory Committee hearings of last December. I hope it will be 
helpful to you as you are making your final decisions about the new 
guidelines. 
You and your staff should feel quite satisfied for having 
conducted such educational and stimulating hearings. Even in spite 
of the marathon-like duration of the sessions, I think most people 
remained interested and became better informed right up to the end. 
I especially benefited from discussions with committee members and 
other witnesses both in the hearings themeselves and at breaks. 
I am, of course, extremely grateful for your inviting me to 
participate in the hearings. They were a welcome opportunity for 
me to represent the Sierra Club in this important issue and to 
present my views. In addition, it was encouraging to see that public 
or non-science oriented input into science-policy discussions can be 
successful and beneficial to both the parties involved and the policy 
questions themselves. I hope you will continue and even make more 
frequent such discussions in the future. 
Again, many thanks. 
Sincerely 
Nancy Pfund
