Q13

Subpart A

Can you please describe what constitutes a facility? For example, if a hospital has four buildings, does the rulemaking pertain to the four buildings as a composite, or to each individually?

Each business calculates their own? And if one of the businesses has several buildings, are they treated as a composite or individually?
