Sec. 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:
    (1) A Class 1 location is:
    (i) An offshore area; or
    (ii) Any class location unit that has 10 or fewer buildings intended 
for human occupancy.
    (2) A Class 2 location is any class location unit that has more than 
10 but fewer than 46 buildings intended for human occupancy.
    (3) A Class 3 location is:
    (i) Any class location unit that has 46 or more buildings intended 
for human occupancy; or
    (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.
    (c) The length of Class locations 2, 3, and 4 may be adjusted as 
follows:
    (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.
