Working with chunks before generation

I've been on a hiatus for a while, I was hoping someone could point me in the right direction. I am attempting to catch chunks before they are generated and set their biome. I've looked into creating a new world with WorldCreator, but it requires me having multiple worlds or doing fancy work to remove the default world. Is there an event I can catch and a method I can use to grab chunks right before they generate, including the initial chunk?

 

Why do you want to modify them before they are created? Why not right after?

Try the ChunkLoadEvent
http://jd.bukkit.org/rb/doxygen/df/d41/ChunkLoadEvent_8java_source.html
It can check if new chunk and can get the chunk object for you.

I want to modify information about the chunk like biome and height before it was made/placed, and I assumed that I would have to therefore catch it, cancel the event, and make the chunk with my settings instead.

Looks like a good place for me to start. Thanks!
