5-4 OWNER / OPERATOR RESPONSIBILITIES AND USE OF MAPPING
PRACTICE STATEMENT: The facility owner or operator collects detailed
location information on existing and newly constructed facilities and provides
mapping data to the one-call centre and locator on a consistent basis.
PRACTICE DESCRIPTION: The facility owner/operator is to provide the one-
call center and locator with data (i.e. electronic or paper records, fiche, or other
indexing of underground facilities), which should enable the following actions:
Ÿ Proper ticket creation and notification of excavation activities near the
facility owner/operator's infrastructure, and
Ÿ The locator to accurately mark the underground facility
Facility owners are encouraged to provide digital information.
The facility owner/operator should ensure as-built drawings are of sufficient
detail. The drawings should also show an accurate relationship to some defined
reference system so that the location of the plant can be re-established at a
later date (i.e. physical permanent structure, survey monuments, and horizontal
and vertical coordinates).
Facility owners are be responsible for verifying any discrepancies reported to
them as part of editing their mapping databases.
The facility owners/operators should apply the mapping system standards
consistently across their facilities. Various plant owners/operators, however,
have standards that may differ from each other.
The facility owner/operator should capture the following information to ensure
project safety in the plan, design, construction, documentation, location, and
maintenance of his or her longitudinal utility:
Ÿ Any new construction into the electronic mapping database in an as-built
state at the time of installation.
Ÿ The location of abandoned or sold facilities is retained in the database.
Ÿ The electronic mapping database includes the following detailed
information:
Engineering stationing and milepost/marker post location, with
latitude and longitude co-ordinates. Common mapping coordinate
systems that allow conversion to latitude and longitude are used.
