Subpart A

What is the definition of a “facility”?

13

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? What if the four separate buildings are connected by above-ground or below-ground walkways/tunnels? What if an industrial campus has several different businesses on its property? Each business calculates their own? And if one of the businesses has several buildings, are they treated as a composite or individually? Additionally, the same would apply for a University that has buildings on one campus, or as in many urban settings, the buildings are located in various addresses in a city.
