Title 92 - TRANSPORTATION
Part 530 - ACCOMMODATION OF UTILITIES ON RIGHT-OF-WAY
Subpart D - SPECIFIC PERMIT CONDITIONS
Section 530.400 - Underground Facilities - Power and Communication Lines
Universal Citation: 92 IL Admin Code ยง 530.400
Current through Register Vol. 48, No. 12, March 22, 2024
a) General
1) Longitudinal lines shall be located as
near the right-of-way line as practicable and no more than eight feet from and
parallel to the right-of-way line.
2) Installation shall have a minimum cover of
30 inches except communication lines installed by the plowed method shall have
a minimum cover of 24 inches.
3)
Underground power cables must be grounded in accordance with the National
Electrical Safety Code (ANSI C2-1990).
b) Fully Access Controlled Highways
1) Longitudinal Lines
A) New underground power and communications
lines longitudinal to the centerline will not be permitted within the
access-control lines of fully access-controlled highways under the following
conditions:
i) When the installation of the
utility would require pavement cuts.
ii) When non-emergency repairs of the utility
would require the use of any part of the highway.
iii) When the installation of the utility
would endanger or impair other utility facilities already in place.
iv) When the installation of the utility
would be above-ground after installation.
v) When the utility would interfere with or
impair the present use or future expansion of the highway.
B) When new underground power and
communications lines are to be permitted longitudinally to the centerline of
fully access-controlled State highways, the following conditions will apply:
i) No above-ground appurtenances will be
allowed on State highway right-of-way.
ii) No utility facilities will be allowed
between the edge of pavement and the back of abutment of the intersecting
roadway at grade separation structures.
iii) Bridge attachments may be allowed as
specified in Subpart G.
2) Underground Crossings
Underground power and communication lines will be permitted to cross fully access-controlled highways under the following conditions:
A) The crossing provides a
transmission or distribution service to a general area or an expanding area. No
individual service crossings will be permitted to cross a fully
access-controlled highway except in cases involving isolated locations such as
landlocked areas.
B) The design,
materials and construction methods shall be those that can be expected to
provide maximum maintenance-free service life.
C) Encasement shall be provided between
jacking or bore pits, if the crossing is installed by boring or
jacking.
D) Encasement may be
eliminated under the following conditions:
i)
The crossing is installed by the use of "moles", "whip augers" or other
approved methods which compress the earth to make the opening for cable
installation.
ii) The installation
is by the open trench method. This method is only permitted prior to roadway
construction.
E)
Above-ground mounted appurtenances to electric power or communication lines
within the access-control lines of fully access-controlled highways will
normally not be permitted except in cases of extreme need. Where installations
are approved, they shall be located within one foot of the right-of-way line or
as near as practicable.
c) Conventional Highways
1) Longitudinal Lines
Underground power and communication lines may be permitted longitudinal to the centerline of conventional State highways under the following conditions:
A) Cable may be
installed by trenching or plowing with consideration given to boring to
minimizing the damages when crossing improved entrances and side
roads.
B) Above-ground
appurtenances constructed as component parts of underground communication or
electric power lines shall be located within one foot of the right-of-way line
or as near as practicable.
2) Underground Crossings
Underground power and communication lines will be permitted to cross conventional highways under the following conditions:
A) The design materials and construction
methods shall be those that can be expected to provide maximum maintenance-free
service life.
B) Encasement shall
be provided between jacking or bore pits, if the crossing is installed by
boring or jacking.
C) Encasement
may be eliminated under the following conditions:
i) The crossing is installed by the use of
"moles," "whip augers" or other approved methods which compress the earth to
make the opening for cable installation.
ii) The installation is by the open trench
method. This method is only permitted prior to roadway construction.
