| (5) A utility shall verify the department's right of
way line on the ground and procure any additional surveys required
by the department before installing the utility facility.
(6) As-built plans or certified as-installed construction
plans must include the installed location, vertical elevations, and
horizontal alignments of the utility facility based upon the department's
survey data, the relationship to existing highway facilities and the
right of way line, and access procedures for maintenance of the utility
facility. All as-built plans must comply with ASCE guidelines and
standards. As-installed construction plans certified by a utility
or its representative shall be submitted to the department for each
relocation or new installation. In the alternative, if approved by
the director of the Maintenance Division or Right of Way Division,
a district may require a utility to deliver either as-installed construction
plans that are certified by an independent party or final as-built
plans that are signed and sealed by an engineer or registered professional
land surveyor. In determining whether to authorize a requirement for
independently certified or signed and sealed plans, the director shall
consider:
(A) the amount of available right of way or the proposed
utility facility's proximity to department facilities and other utility
facilities that may be impacted;
(B) the type of utility facility; and
(C) past performance of the utility in providing accurate
location data and conformance with its certified as-installed construction
plans.
(7) If approved by the director of the Maintenance
Division or the Right of Way Division, a district may require a utility
to deliver plans that are signed and sealed by an engineer. In determining
whether to authorize a requirement for signed and sealed plans, the
director shall consider:
(A) the amount of available right of way or the proposed
utility facility's proximity to department facilities or other utility
facilities that may be impacted;
(B) the complexity of required traffic control plans;
(C) the type of utility facility;
(D) whether the installation or adjustment activity
requires a storm water pollution prevention plan; and
(E) the utility's past performance in providing accurate
location data and conformance with its construction plans.
(d) Tunnels and bridges.
(1) Fuel tanks, including storage tanks for petroleum
or compressed gases, may not be within 100 feet of a highway structure.
(2) In providing a utility tunnel or utility bridge,
the requirements in subparagraphs (A) - (I) of this paragraph apply.
(A) Mutually hazardous transmittants, such as fuels
and electric energy, shall be isolated by compartmentalizing or by
auxiliary encasement of incompatible carriers.
(B) The utility tunnel or utility bridge structure
shall conform in design, appearance, location, bury, earthwork, and
markings to the culvert and bridge practices of the department.
(C) Where a pipeline on or in a utility structure is
encased, the encasement shall be effectively opened or vented at each
end to prevent possible build up of pressure and to detect leakage
of gases or fluids.
(D) Where encasement is not provided for a pipeline
on or in a utility structure, additional protective measures shall
be taken, such as employing a higher factor of safety in the design,
construction, and testing of the pipeline than would be required for
cased construction.
(E) Broadband service, communication, and electric
power lines shall be insulated, grounded, and carried in protective
conduit or pipe from the point of exit from the ground to reentry,
and the cable carried to a manhole located beyond the backwall of
the structure.
(F) Carrier pipe and encasement for gas, liquid petroleum,
hazardous product, and water lines shall be insulated from electric
power line attachments.
(G) Sectionalized block valves shall be installed in
lines at or near ends of utility structures, pursuant to 49 CFR §192.179,
Transmission Line Valves, unless segments of the lines can be isolated
by other sectionalizing devices within a distance acceptable to the
department.
(H) Any maintenance, servicing, or repair of the utility
facilities is the responsibility of the utility.
(I) The utility shall notify the district 48 hours
in advance of any maintenance, servicing, or repair; however, in an
emergency situation, the utility shall notify the district as soon
as practicable.
(3) If a utility facility exists on the utility's own
easement and it would be more economical to the department to adjust
the utility facility across a highway by use of a utility tunnel or
bridge rather than to provide separately trenched and cased crossing,
consideration should be given to provision of such a structure. Where
the utility facility was placed through an approved use and occupancy
agreement and the adjustment of the utility facility is the sole responsibility
of the utility, the department may allow for the provision of a utility
structure without cost to the department, provided the conditions
outlined in subsection (a) of this section and all other pertinent
requirements are met. If a structure is to serve as a joint utility/pedestrian
crossing or a joint utility/sign support structure, the department
will participate to the extent necessary for accommodation of pedestrians
or highway signs only.
(e) Joint use of utility and highway structures.
(1) The attachment of utility facilities to bridges
and grade separation structures is prohibited if other locations are
feasible and reasonable.
(2) Where other arrangements for a utility facility
to span an obstruction are not feasible, the utility may submit a
request to the district for attachment of the utility facility to
a bridge structure through a bridge attachment agreement. Each attachment
will be considered on an individual basis, and permission to attach
will not be considered as establishing a precedent for granting of
subsequent requests for attachment.
(A) When it is impractical to carry a self-supporting
communication line across a stream or other obstruction, the department
may permit the attachment of the utility facility to its bridge. If
approved on existing bridges, the utility facility shall be enclosed
in a conduit and so located on the bridge structure as not to interfere
with stream flow, traffic, or routine maintenance operations. When
a request is made before construction of a bridge, if approved, suitable
conduits may be provided in the structure if the utility bears the
cost of all additional work and materials involved.
(B) If it is the department's responsibility to provide
for the adjustment of telephone lines or telephone conduits to accommodate
the construction of a highway and the adjustment provides for the
placement of telephone conduits in a bridge, the department will allow
a reasonable number of spare telephone conduits in the structure if
the spares are placed at the time of construction and the telephone
company bears the cost of the spare conduits.
(C) A utility may not attach a utility facility to
a bridge without the written approval of the executive director.
(D) Power lines carrying greater than 600 volts are
prohibited on bridges.
(E) When a utility is granted permission to attach
a utility facility to a proposed bridge prior to construction, any
additional costs associated with the design or construction to accommodate
the utility facility are the responsibility of the utility.
(F) A utility requesting permission to attach a utility
facility to an existing bridge shall submit sufficient information
to allow the department to conduct a stress analysis to determine
the effect of the added load on the bridge structure. The department
may require other details of the proposed attachment as they affect
safety and maintenance.
(G) A utility shall ensure that water and wastewater
facilities attached to a bridge are not susceptible to leaks and do
not damage the highway facility. The utility shall ensure that all
utility facilities attached to a bridge do not adversely affect the
serviceability of the bridge. As-built plans of the attached utility
facility must be signed and sealed by an engineer.
(f) Aesthetics. A utility shall notify the department
before removing, trimming, or replacing trees, bushes, shrubbery,
or any other aesthetic features. The department must approve the extent
and method of removal, trimming, or replacement of trees, bushes,
shrubbery, or any other aesthetic feature.
(g) Design and construction responsibility.
(1) The utility is responsible for the design of the
installation, adjustment, or relocation of a utility facility.
