any activity involving a regulated substance, including any use, storage,
manufacturing, handling, or on-site movement of the substance or any
combination of these activities. Any group of vessels that are interconnected,

substance potentially could be involved in a release,
are considered a single process. (31)(32) "Produced water"
means water extracted from the earth from an oil or natural gas production

means off-site residences, institutions such as schools or hospitals,
industrial, commercial, and office building, parks, or recreational areas

release. (34)(35) "Regulated
substance" means a toxic or flammable substance listed in rule
the Administrative Code. (35)(36) "Replacement in
kind" means a replacement that satisfies the design specifications. (36)(37)

plan " or "RMP" means a risk management plan required in rule
of the Administrative Code. (38)(39) "Stationary
source" means any buildings, structures, equipment, installations, or
substance-emitting stationary activities that belong to the same industrial
group as described in the standard industrial classification manual, 1987, that
are located on one or more contiguous properties under the control of the same
person or persons (or persons under common control), and from which an
accidental release may occur. Properties shall not be considered contiguous
solely because of a railroad or pipeline right-of-way.

"Vessel" means any reactor, tank, drum, barrel, cylinder, vat, kettle, boiler,
pipe, hose, or other container. (41)(42) "Worst-case
