I'm buying 40000 sq ft commercial contaminated warehouse. Has anyone dealt with contaminated commercial building before?

According to existing owner the site needs 500k in decontamination. But I would double it just being on the safer side. I'm doing Env Phase 1 and will be doing Phase 2 afyer phase one.

Main concerns that 4 gov agencies: MN pollution control, mn dept of agriculture, the City of Mpls and Hennepin county will send me some work orders for site clean up after I buy the building and it will cost me more $.

I know that I will be requesting a letter of release from liabilities from MN Polution control and no one at 3 other Gov agencies was not able to give me a clear answer what work orders will they require me to do after I purchse the property. Has anyone ever done anything like that?
