1.4
Confirm complete understanding of the scope, objectives and timeline for the audit.
1.5 Prior to any work at each refinery, the Auditor
must satisfy any contractor requirements for entry such as Contractor orientation
training, drug screening or any other mandated requirements. Time to meet these
requirements will be built into the audit.
1.6 Prior
to the start of the audit, the auditor will conduct an opening conference to outline
the work that will be conducted during the audit. As part of this conference a
daily update time will be announced so interested parties can listen to a summary

provide a final update on the audit prior to the Auditor leaving the site.
1.7
The Auditor shall provide the monitoring equipment to be used for the comparative
monitoring activity. The Facility shall be informed of the type of equipment to
be used prior to the audit. Only intrinsically safe rated equipment will be acceptable.
The Auditor shall also have a backup plan for providing replacement-monitoring
equipment should the original equipment fail.
1.8
An agreement on calibration gases shall be reached prior to the audit. If the
Auditor is to provide the gases they must be on site and ready for use prior to
the audit. An internal approval process may be required prior to bringing these
gases on site.
1.9 Establishment of a monitoring
plan for the comparative monitoring will be agreed upon prior to the audit.

FIELD ACTIVITIES
12.1 Comparative Monitoring:
As part of the LDAR audit, comparative monitoring shall be conducted on the following
equipment. This is a suggested method. The Facility will entertain any suggestions
by the auditor for more appropriate methods based on auditor's experience and
benchmarking with industry standards. The Facility may, at their discretion, have
the contract LDAR technician monitor the same components as the auditing team.
Valves and Control Valves- Ten (10) percent of the total valves in the LDAR program.
Pumps- Ten (10) percent of pumps in the LDAR program

inspecting those selected areas, reviewing all light and heavy components within
those areas, verify proper identification by comparing field information with
P&ID and stream data. Approximately three (3) percent of each process unit will
be randomly reviewed. If an alternative monitoring plan is agreed upon, a complementary
method of reviewing components may be suggested by the Auditor and approved by
the Facility.
