Environmental Remediation Deal near Ashland Ohio

[Pace J.]

I've got a unique project and hope for some feedback:

A client of mine is trying to figure out what to do with some land in Loudonville Ohio (Ashland County OH) that is currently undergoing environmental remediation (undertaken by the previous owners).  My client already sold off the most valuable parcels that included manufacturing facilities (not residential), but this 6+ acres of land remain. Note that any development of the 6+ acres of land is restricted to industrial or commercial use, and any new construction on the land will have to be approved by the Ohio EPA.  

Loudonville is a small town (pop. 2500).  Any thoughts as to how the owner can best utilize the land if she doesn't sell?  If not, would you know someone in the area who might have experience with environmentally remediated properties? I'm happy to provide more details.

Any advice is much appreciated. Thanks.
