Not really an issue here to speak of unless you're close to the water.

Ocal is fairly common where the environment is an issue.

I've seen and heard horror stories in the bay area though (SF) from the use of PVC, especially on roofs. Lots of fires and lawsuits over the use of PVC.

It's done, just not a common practice here from what I've seen.
