Annual Implementation Audit
This audit determines whether the written program has been developed according to the guidelines in API RP 1162 and assesses whether the program has been implemented as described in the written program. API RP 1162 §8.3 lists 3 options for conducting the implementation audit:
- Internal working group
- Third-party
- Federal or State pipeline safety regulator
The clearinghouse review of programs that occurred from October 2006 through October 2007 cannot be counted as an implementation audit, since the clearinghouse did not review the implementation of the program.
