what specific chemicals are emitted by the facility and their
emission rates.

Some background reading may be helpful. We have some fact
sheets available:
What are VOCs and do Printing Related Materials
Contain Them, <>.
What is a Hazardous Waste?

dispersed by using a simple computer model available from the U.S.

regulators to give such a quick assesment. It can be obtained free,
complete with instructions, from

If you know the pollutants and their concentrations, you can
compare them with U.S. regulatory concentrations. I am familiar
with the regulations in my home state of Wisconsin. The emission
rates of hazardous chemicals which are deemed to be safe and thus
are allowed by my state are listed on the web in section NR445 of

This information can give you a basis to assess the situation for
