In this second installment of the Brownfield Braintrust Podcast, Matt Winefield discusses ten flaws with the Cal-EPA 0.03 attenuation factor (AF) in the Draft Vapor Intrusion Guidance Document. All parties agree that the AF should be based on best available science. Best available science dictates that Cal-EPA must use the AF developed in the 2020 DTSC attenuation factor study, which utilized California data exclusively and has been extensively peer reviewed.

Matt Winefield interviews Ignacio Dayrit, Director of Programs for the Center for Creative Land Recycling. CCLR is the oldest and only national non-profit working exclusively to champion land cleanup and reuse. It is an independent, third-party force for the sustainable and equitable reuse of land with expertise in cleaning up and redeveloping vacant or contaminated properties, sometimes referred to as "brownfields.” CCLR offers training and technical assistance for communities working to turn this land around, and it advocates for policy change at the federal, state and local levels to make land reuse possible in more places.
