Vapor Intrusion - 5 Factors of Successful Remediation

VI remedies can be expensive and time-consuming. The best approaches balance state regulatory requirements, assessment costs, mitigation technology, financial incentives, and the property owner’s business needs.

SME has helped identify VI issues and develop remediation plans at numerous sites across Indiana, Michigan and Ohio. Our team can help you navigate all of the complexities of your VI challenge.

Regulatory requirements – Regulatory requirements have been in a state of flux for several years. A complete understanding of the regulatory requirements that govern VI requires a general understanding of how environmental regulations develop and are implemented; a specific understanding of the ways in which VI regulations have changed over the past several years; and the current status of Michigan law, as adopted in late 2018.

Assessment Costs – Every VI project needs assessment, but what kind do you do, how much do you do, when do you do it? Predevelopment or preacquisition activities are especially costly, so it’s essential to avoid unnecessary work. At the same time, inadequate scopes that can lead to costly corrections later.

Mitigation Technology – What solution is the right one for your problem? Do need a vapor barrier and/or a subslab depressurization system? Would source removal make sense? Or maybe you don’t have an issue at all, and you can demonstrate due care through monitoring.

Financial Incentives – Grants, eligible cost reimbursement, and low-interest loans are available to support vapor mitigation. Each incentive takes time and comes with a cost, so you need to fully understand the programs and select the incentive that is best for your project. Does the potential benefit of an incentive outweigh the cost and time to apply? And, how do you evaluate uncertainty?

Business Needs – Every project has its own needs and objectives. When does the owner need the site to be operational? How intrusive can solutions be? Does The Owner have the capacity to fund? Are there tenants? What types of activities will be conducted onsite? What is the likelihood of renovation and repairs over time? What is the capacity for operations and maintenance? All of these questions need to be answered and evaluated in order to ensure the VI solution makes business sense for the property owner.

Watch for upcoming blogs that will explore each of these factors and provide valuable insight into VI best practices.
