I represent a number of lenders on environmental issues. if you have solvents migrating off-site, you may not only possibly become a responsible party but also could become subject to toxic tort suit for property damage. your lawyer should advise you on the wisdom of enrolling in the state brownfield or voluntary cleanup program. to maintain liability protection, you need to exercise "appropriate care". doing work pursuant to a state agreement will generally provide you with such protection. you probably wont be able to get insurance coverage for on-site cleanup but might be able to get coverage for off-site claims.

Figure out what kind of role you envision for yourself.

Chris, rather than just preaching at us all weekend, shakes it up a bit and we do some role playing and we do a fun exercise designed to make us ask better questions.
