§ 73.609 Zones.
(a) For the purpose of allotment and
assignment, the United States is divided
into three zones as follows:
(1) Zone I consists of that portion of
the United States located within the
confines of the following lines drawn
on the U.S. Albers Equal Area Projection
Map (based on standard parallels
29 1/2° and 45 1/2 °; North American datum):
Beginning at the most easterly point
on the State boundary line between
North Carolina and Virginia; thence in
a straight line to a point on the Virginia-
West Virginia boundary line located
at north latitude 37°49' and west
longitude 80°12'30"; thence westerly
along the southern boundary lines of
the States of West Virginia, Ohio, Indiana,
and Illinois to a point at the junction
of the Illinois, Kentucky, and Missouri
State boundary lines; thence
northerly along the western boundary
line of the State of Illinois to a point
at the junction of the Illinois, Iowa,
and Wisconsin State boundary lines;
thence easterly along the northern
State boundary line of Illinois to the
90th meridian; thence north along this
meridian to the 43.5° parallel; thence
east along this parallel to the United
States-Canada border; thence southerly
and following that border until it again
intersects the 43.5° parallel; thence east
along this parallel to the 71st meridian;
thence in a straight line to the intersection
of the 69th meridian and the
45th parallel; thence east along the
45th parallel to the Atlantic Ocean.
When any of the above lines pass
through a city, the city shall be considered
to be located in Zone I. (See Figure
1 of § 73.699.)
(2) Zone II consists of that portion of
the United States which is not located
in either Zone I or Zone III, and Puerto
Rico, Alaska, Hawaiian Islands and the
Virgin Islands.
(3) Zone III consists of that portion of
the United States located south of a
line, drawn on the United States Albers
Equal Area Projection Map (based on
standard parallels 29.50 and 45.50 North
American datum), beginning at a point
on the east coast of Georgia and the
31st parallel and ending at the United
States-Mexican border, consisting of
arcs drawn with a 241.4 kilometer (150
mile) radius to the north from the following
specified points:
North latitude West longitude
(a) ........ 29°40'00" 83°24'00"
(b) ........ 30°07'00" 84°12'00"
(c) ........ 30°31'00" 86°30'00"

(h) ........ 28°43'00" 96°39'30"
(i) ........ 27°52'30" 97°32'00"
When any of the above arcs pass
through a city, the city shall be considered
to be located in Zone II. (See Figure
2 of § 73.699.)

In certain instances an interpretation of this data was made
which may not reflect the legal position of the United States.
