Volume 5: Response activity for the VIAP
Attachment B.5-3 – Operation, maintenance, and monitoring (OM&M) of a passive vapor mitigation system (PVMS)

The purpose of OM&M is to document and ensure the PVMS continues to function as designed until the vapor source(s) no longer poses an unacceptable risk to receptors. During the OM&M, the PVMS continues to be operated, maintained/repaired, and monitored in accordance with the performance metrics established during the Installation and Commissioning.

Repairs or modifications to PVMS should be handled in a manner consistent with contingency actions or a contingency plan established for non-performance of specific system components and the design performance requirements associated with each. Any new additions or significant modifications to the PVMS moves the PVMS back into Phase 2 – System Installation/Commissioning.
