(b) The statement of justification shall show that the request cannot be obviated by design changes to the proposed facility, the request is the minimum necessary, and the adverse impacts of granting the request are mitigated to the maximum extent practicable. The statement shall include a demonstration:

1. (1) for requests grounded in the existing technology, that there are technological limitations (including governmentally imposed technological limitations) related to necessary facility component bulk, layout, process or materials that make compliance by the applicant technically impossible, impracticable or otherwise unreasonable;
2. (2) for requests grounded in factors of costs or economics (likely involving economic modeling), that the costs to consumers associated with applying the local legal provision outweigh the benefits of applying such provision; and
3. (3) for requests grounded in the needs of consumers, that the needs of consumers for the facility outweigh the impacts on the community that would result from refusal to apply the local legal provision.
