I have a professional question that falls outside of my planning knowledge. I am looking at a project near my work and home that is proposing a zone change from a formerly industrial site (lumber related industries) to residential townhouses. The applicant has submitted a letter from the state environment department's underground petroleum storage tank division stating that remediation has been completed and cites a number of reasons why (differnet monitoring devices, etc.). That is the extent of information provided as far as contamination and cleanup at the site which was known for serious airborn and ground pollution.
The organization I work for has developed sites on adjacent tracts and we did produce additional documentation from the state environment department related to groundwater contamination. The current applicant has not produced any such document and we have concerns that they are trying to skirt this issue in their application. I have left three messages in the last week with the state environment department, but have not received a call back so I am trying to educate myself as best I can otherwise.
My questions are:
1) are there different standards of remediation required for residential versus industrial use? Are there names for these (I see things like tier 1, 2, 3, etc but don't really know what they mean) that are likely to translate from state to state? I want to be able to ask them "have you done a XXXX assessment on the site?" but I need to knwo what I am talking about.
2) if someone was doing what I describe above in your municipality, do you know what sort of documentation would be required to allow residential development on a formerly contaminated industrial site?
I realize some fo this information is likely to be state or city-specific, but I thought I would cast my net and see what I catch.
Thanks for any help you all can provide!
