Epa Registered

What is the EPA registered list for spot on flea and tick products about?
Is it a list of registered bad products or a list of good products?
I read the article about this in my local newspaper anf according to it, the EPA was pulling the list they originally posted listing flea products that were dangerous. Other papers reported it as well. Since then the list has been pulled. don’t know why. Follow the money.
