192.5—Class locations.
(a)
This section classifies pipeline locations for purposes of this part. The following criteria apply to classifications under this section.
(1)
A “class location unit” is an onshore area that extends 220 yards (200 meters) on either side of the centerline of any continuous 1- mile (1.6 kilometers) length of pipeline.
(2)
Each separate dwelling unit in a multiple dwelling unit building is counted as a separate building intended for human occupancy.
(b)
Except as provided in paragraph (c) of this section, pipeline locations are classified as follows:
(2)
A Class 2 location is any class location unit that has more than 10 but fewer than 46 buildings intended for human occupancy.
(ii)
An area where the pipeline lies within 100 yards (91 meters) of either a building or a small, well-defined outside area (such as a playground, recreation area, outdoor theater, or other place of public assembly) that is occupied by 20 or more persons on at least 5 days a week for 10 weeks in any 12-month period. (The days and weeks need not be consecutive.)
(4)
A Class 4 location is any class location unit where buildings with four or more stories above ground are prevalent.
(1)
A Class 4 location ends 220 yards (200 meters) from the nearest building with four or more stories above ground.
(2)
When a cluster of buildings intended for human occupancy requires a Class 2 or 3 location, the class location ends 220 yards (200 meters) from the nearest building in the cluster.
