FYI - just to give people an update.
I have 6 pines 20-25' tall affected. I received my resolution packet at the beginning of June which basically said replace 5 and do maintenance on 1. I sent back a counter one week later saying I'm Ok with everything except all 6 are dying so I'd like to replace all at once rather than replacing 5 and then waiting a year and replacing the 6th. It's been 4 months and just received a call from DuPont that there lawyers reviewed my counter and they want to send out one of their people to do a new review. Before they scheduled they did ask if I had retained an outside attorney-which I have not (yet).
