I find it interesting that all states prohibit use on non porous surfaces and some are picky about when you can apply it, if you're allowed to do so, to frozen ground. Hello? Why would anyone waste money trying to green up their driveway or feed sleeping plants? Chemicals applied with common sense should not result in substantial runoff problems; the plant needs the "bad stuff" and will use that if the proper quantity is applied. (Saving the Bay in MD was/is a huge deal; large scale chicken farms/houses deposited manure for years too close to waterways and caused major issues.)
