If you have chemical run off, your neighbor could be drinking it...I assume that they are going to have you fill it with different layers of clean dirt in order to provide filtration and not just gravel.

Same thing for some wanna-be areas zoned industrial that are languishing since no one is dumb enough to do industrial close in (nasty chemical and logisitics affected by ZERO investment in freeways).3.

I have a sales job in the chemical industry where I've been employed 17 years that I can run remotely for a week to a month at a time.   

@Nathan SmithDude go to Ohio State and major in mechanical/electrical/chemical/software engineering.

@Perry Livingston I just closed an Indy refi with Chemical Bank.
