It's not like the EPA does no testing, but what about the unknowns? For example, men's sperm counts have gone down 50% over the last 30 years and scientists have no solid explanation (despite >1000 journal articles on the topic).
Are you confident that pesticides play no role in this? Or autism? Or immune disorders?
The EPA doesn't even try do testing on long-term exposure to a low-dose of substances, which is exactly what is described in the article.
Calling the EPA "fallible humans" is laughable. The question is - is the EPA process systematically too trusting of new chemicals? I have my answer.
I recommend you start your education on this topic with "The precautionary principle." http://www.euro.who.int/__data/assets/pdf_file/0003/91173/E8...
