You can find all the feeral regs on-line. But that doesn't help much, because they're huge. Check the epa website for the RCRA orientation manual, and the CERCLA orientation manual. I think I posted links in here somewhere. Those give good overviews of those two. And of the two, I'd concentrate on RCRA - especially on how to determine what a hazardous waste is.
If you can find someone with paper copies of the CFRs, that's the best way to get the regs. But I wouldn't worry about it too much. There are really just too many CFRs to practicably take with you, so it's best to just find a decent textbook type rerference that glosses over the most important parts. For me, the different books I used all contained enough information related to the regulations for that particular subject (water, air, haz waste, etc) that I was able to pass, although I did miss a question or two directly because I didn't have a particular federal regulation.
Maybe VTE's book will work well, I just don't know. Does it cover regulations in addition to just the statutes?
