USE OF RECORDS
PRACTICE STATEMENT:
Facility locators use on-site facility records at all
times. The order for relying on records should be:
1.
On site records
2.
Archive records
3.
When no records are available, alternative save methods (i.e.
electromagnetic or vacuum excavation)
PRACTICE DESCRIPTION:
Facility locators use on-site records at all times.
Facility records can indicate approximate location, number of facilities, and
access points for buried facilities within a requested area. The use of facility
owner/operator supplied accurate records is an effective method of identifying
facilities as part of the locating process.
It may be necessary to delay the completion of the locate while archives are
accessed, requiring immediate notification of all parties, under the following
circumstances:
Ÿ
Records are not available on-site and electromagnetic techniques cannot be
used (for example, no tracer wire), and
Ÿ
As-built/as-constructed records are available on-site but there exists no
electromagnetic or alternative technique to physically locate the facility.
When as-built/as-constructed records are not available on-site but there exists
an electromagnetic or alternative technique to physically locate the facility, the
locate should be completed by the available technique and verified where
possible with the facility owner/operator.
It can be useful for the locator to have a locate process checklist to prompt the
use of records at all times when on site.
