of excavation to all owners of underground facilities through a one-number locator service. All owners of
underground facilities within a one-number locator service area shall subscribe to the service. One
number locator service rates for cable television companies will be based on the amount of their
underground facilities. If no one-number locator service is available, notice shall be provided individually
to those owners of underground facilities known to or suspected of having underground facilities within
the area of proposed excavation. The notice shall be communicated to the owners of underground
facilities not less than two business days or more than ten business days before the scheduled date for
commencement of excavation, unless otherwise agreed by the parties.
Upon receipt of the notice provided for in this section, the owner of the underground facility shall provide
the excavator with reasonable accurate information as to its locatable underground facilities by surface-
marking the location of the facilities. If there are identified but un-locatable underground facilities, the
owner of such facilities shall provide the excavator with the best available information as to their locations.
The owner of the underground facility providing the information shall respond no later than two business
days after the receipt of the notice or before the excavation time, at the option of the owner, unless
otherwise agreed by the parties. Excavators shall not excavate until all know facilities have been marked.
Once marked by the owner of the underground facility, the excavator is responsible for maintaining the
markings. Excavators shall have the right to receive compensation from the owner of the underground
facility for costs incurred if the owner of the underground facility does not locate its facilities in accordance

appurtenances if the presence of existing service laterals or appurtenances on the site of the construction
project can be determined from the presence of other visible facilities, such as buildings, manholes, or

fulfill an obligation under this chapter, the party failing to perform that obligation shall be liable
for any damages. Any clause in an excavation contract which attempts to allocate liability, or

provisions of the chapter is against public policy and unenforceable. Nothing in this chapter
prevents the parties to an excavation contract from contracting with respect to the allocation
of risk for changed or differing site conditions.
