Plan of Correction and IDRs

Thanks for all the replies. Unfortunately, my corp. has decided against an IDR (Informal Dispute Resolution). I remain clueless as to why they would accept rather than fight a G tag, but they are not obligated to tell me why.
This is how they "help": I wrote most of the plan, my DSN added what she thought was right. One person from corporate came down and changed them and once I had those done, another corp. person came and changed them again! ...why don't they just send a team and do it themselves instead of wasting our time?!?! The good thing is we finished the POC yesterday and now can get back to regular...at least until the DPH comes back for re-survey.
