Developing an Effective Vapor Intrusion Mitigation System (VIMS) Operations, Maintenance and Monitoring Plan (OM&M)
Post mitigation OM&M programs are typically proposed as part of the commissioning report, but even in states where these programs are required very few are ever implemented. Many existing systems have become orphaned artifacts of commercial real estate transactions. Building owners and occupants are often unaware of the VIMS-intended function and why it is in a building. An upswing in Litigation and Long-Term Liability concerns has caused consultants and regulators to take a fresh look at this long overlooked but important component of vapor intrusion mitigation.
This presentation will:
• Explain the purpose of an OM&M program, how to incorporate OM&M components into the VIMS design and achieve regulatory requirements.
• Discuss the essential elements of an effective program, the integration of riser pipe, indoor air sampling, reporting formats and timetables.
• Demonstrate how to integrate the OM&M program into the extended stewardship plan and the importance of establishing a reserve escrow account that includes projected OM&M support costs.
• Look at the integration of electronic motoring and accrued cost savings of response driven controls and how those savings can mitigate extended stewardship cost.
• Conclude with strategies for decommissioning systems and how those strategies can be integrated into an OM&M program.
