Green Cleaning Plan Compliance

I understand the use of the EBOM green cleaning requirements to establish your plan for an NC ID credit. However, an intrinsic part of an EBOM plan is the compliance metrics. So does that mean that our NC Green Cleaning plan only needs to demonstrate 20% compliance with the chemicals and equipment being used? And what about the standards being used? EBOM reviewers will not permit any compliance standards that are not listed in the reference manual. Can an NC green cleaning plan elect to use an industry standard other than GreenSeal or Environmental Choice?
