"Cover" The depth of earth or backfill over buried utility pipe or conductor.


"Department" The Illinois Department of Transportation.


"Department Approved" The approval of the Department requires compliance with this Part. The Department's approval shall be consistent with commonly recognized and accepted traffic control and construction principles, including material selection, and with sound engineering judgment.


Unless otherwise provided in the permit or in this Part, the following Departmental publications shall serve, inclusively and not exclusively, as examples of such principles and standards:


Standard Specifications for Road and Bridge Construction


Supplemental Specifications and Recurring Special Provisions


Highway Design Manual


Highway Standards Manual

If the Department finds a discrepancy between differing principles, it shall determine which principles apply. If requested, the Department shall state what standard will apply to the construction, maintenance, or operation of a facility in the future.


The Department's determination will not be changed unless it finds that the determination was incorrect or that a new standard is clearly superior to the earlier standard. If the Department makes such a finding, it shall notify in writing all parties to whom it had given its earlier determination.
