Dear Secretary Abruzzo,

I am writing in regard to decisions that your office will be making about unconventional natural gas extraction (UGE). Some of these decisions may relate specifically to children, such as decisions about setbacks between UGE sites and schools. Other decisions may relate to UGE in a broader sense. As a physician with significant expertise in environmental health*, I want to point out that there is no information in the medical or public health literature to indicate that UGE can be implemented with a minimum of risk to human health.
