FAQ

Q: What is the purpose of Form EQP4470?
A: The purpose of Form EQP4470 is to assess precluding factors for petroleum vapor intrusion (PVI) lateral inclusion zones in Michigan.

Q: What is petroleum vapor intrusion (PVI)?
A: Petroleum vapor intrusion (PVI) refers to the migration of petroleum vapors from contaminated soil or groundwater into buildings or other enclosed spaces.

Q: What is a lateral inclusion zone?
A: A lateral inclusion zone is an area identified around a petroleum release site where PVI may occur due to lateral movement of vapors.

Q: Why is it important to assess precluding factors for PVI lateral inclusion zones?
A: Assessing precluding factors helps determine potential risks and the need for mitigation measures to prevent PVI in affected areas.

Q: Who is responsible for conducting the precluding factors assessment?
A: The responsibility for conducting the precluding factors assessment lies with the party responsible for addressing the petroleum release site.

Q: What are some examples of precluding factors?
A: Precluding factors can include the presence of an effective vapor intrusion barrier, distance from the contamination source, soil type, and building characteristics.

Q: Are there any regulations or guidelines for PVI assessments in Michigan?
A: Yes, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) provides guidelines and regulations for conducting PVI assessments, including the use of Form EQP4470.

Q: What happens if precluding factors are not adequately addressed?
A: If precluding factors are not adequately addressed, there is an increased risk of petroleum vapors entering buildings, potentially posing health risks to occupants.

Q: Can the precluding factors assessment be used for other types of vapor intrusion?
A: The precluding factors assessment on Form EQP4470 is specifically designed for petroleum vapor intrusion (PVI) lateral inclusion zones.

Q: How often should the precluding factors assessment be conducted?
A: The precluding factors assessment should be conducted as part of the initial site investigation and whenever there are significant changes at the petroleum release site that may affect PVI risks.
